Invention Patent descriptive report of "COMBINE WITH FLEXIBLE SUSPENSION AND TURNING SHOE HEADER".

This invention refers to a cereal Combine intended to provide a new layout for manufacturing this type of equipment and it will count on a Frame endowed with flexible suspension. Front mobile steering. Bringing the innovation of a huller Set with cylinder of three hammer phases and sieves that work with tracks system and hammers in a snail shape. Everything linked to a harvest header with a bowing system of the reel set and feeding shaft and with side oscillation provided by pendulum fitting systems. The Combines known in the market are very efficient; however, they have some inconveniences that impair their work efficiency to be totally explored. There are still some inconveniences in mounting the operation devices so that besides rendering the operation for the workers they also present risk for security and quality losses of the cereals harvested. Some of these inconveniences may be mentioned as an example, such as the existing Combines unload system which is installed beside the cabin entrance (left), so that, when making the unload of the cereals harvested, the operator has too much difficulty with the dust excess formed in the cabin entrance. Another remarkable inconvenience is that the existing Combines sieves system relies only on one or two falls and does not offer regular forms to increase them, which are responsible for the first phase of separation of the cereals already threshed by the impurity thresher cylinder, such as rests of dust, little pod fragments, straws, etc. There is also the inconvenience that become a security matter, which is the fact that the cereals unload is made by shafts with endless thread, both in the containers under the sieves and in the internal part of the bulk carrier, and there are even cases of people who lost hands or arms in these shafts with endless thread which work like mincers, and in addition to this the system ends up spoiling, even minimally, the cereals, which lose their quality.

The existing Combines are not manufactured with the hydraulic Cylinder system in the front suspension and that has been introduced in

this invention, so that they don't have a damping system and a system of vertical movement of the front wheels, which provides a suspension flexibility; therefore eliminating this problem.

Another common aspect of the existing Combines refers to the sieves Set in the lower part of the thresher cylinder where it is impossible to proceed with the adjustment in certain parts of the sieves, considering that the sieves (concave) of the existing combines contain only one phase and start in the Combine's intermediate part and the entire parts are formed by big trays or sieves, causing big inconveniences in the harvesting of some kinds of harvests, such as corn and wheat etc, since as it is impossible to adjust the height of the sieves or the trays, the quality control of the grains threshed is made difficult.

Headers that enable a suspension vertical bowing system are not known and they allow the harvest cutting and feeding devices to have a bowing in shape of suspension and we also don't know that Headers move vertically by means of pendulums like this claim.

Considering all these difficulties and inconveniences and attempting to overcome them, we have developed this Combine, object of the claims, and it will be better understood by means of the figures attached, where: Figure 1 represents the Combine duly mounted with a perspective sight.

As the figures enclosed illustrate we consider that this invention is composed by the cereal Combine (01) mounted with a grains separator Set (02); a thresher Cylinder Set (03) which is covered by a higher cover (04) with a retrack return Opening (05) This Combine will still count upon a harvest Header (06) endowed with a creeping Reel (07), one operation cabin (13) installed in its soil (08), with the installation of the bulk carrier Tank in its higher part (23) the grains Elevator in the right side (12) and the retrack Elevator in the left side (30), also containing a back Cowl (14) which is driven like an opening and closing door by means of the Hinges (16) and of the Lock (17) for the internal maintenance, by the back part of the thresher Cylinder (03) and the sieves Set (47/56), and also the side protection Walls (31) that have maintenance Windows (32).

The harvest Header (06) is linked to the Straw

Elevator (302) through the engagement Support (335) which is endowed with Fitting (336) and head movement Guide (318) with guide Pin (317) and is composed by the higher Frame (304) so as to free the hydraulic Pistons (307-A), besides containing the side suspension Guides (321), forming the set sustaining Frame responsible for the harvesting, which are: The Reel Set (07), the snail Shafts (312) and the feeding Shaft (313), all fitted to the intermediate Frame (303) which in turn is fixed to the inner Frame (347) composed by at least one Longeron (348) fixed in the lower part of the hydraulic Pistons (307-A) and that has a frontal formation with a sufficient number of Shoes Set (306) that receive the adjustment Plates (310) and are developed so as to flex themselves in the frontal part due to their division formed by the joining (322).

The Reel Set (07) is fixed to the lower Frame, through the side sustaining Arms (330), directly in the suspension guide Supports (305), is formed by the mounting of the vertical Supports (325) and the side Arches (349), so that between the vertical Supports (325) and the side Arches (349) we have the mounting of the thrust Bushing (328) and the fixing joining (329) inserting with the side Arches (349) until we obtain the formation of the desired length of the Reel Set which is responsible for working in a turning steering provided by hydraulic systems or by mechanical or manual motive power allowing the regulation of the height, of advance or rearward or even of leveling so that the, when turning, the Reel Set (07) pulls the branches of the crop harvested over the Cutting Bar (350) so that for pulling

the plants the Clamps (327) are installed in the vertical supports (325) by a thread fitting by means of a lower Guide (326) which is fixed in the lower part of the vertical Supports (325) and is intended to enable the pressure adjustment of the Clamps (327) that can be positioned back and forth or even in the middle of the vertical Supports (325).

The snail Shafts (312) that have maintenance opening (314) are responsible for taking the cut and harvested plants up to their center due to their endless thread system so that the branches or plants (straws) are collected to inside the straw Elevator (302), after getting in the center, through the feeding Shaft (313) which has Fingers (313-A).

The intermediate Frame (303) is responsible for receiving both the reel Set (07), through its sustaining Arms (330) and the feeding set formed by the snail Shafts (312), as well as by the feeding Shaft (313) so that this feeding Shaft (313) is fixed in the center and by the sides of the snail Shafts (312) which in turn are side fixed in the intermediate Frame by means of the lower sustaining Arms (331), and all these devices are fixed in the suspension guides Supports (305) which are fixed on the Shoes Sets (306) and are introduced by free fitting into the sustaining Guide (321 ) and this intermediate Frame has a protecting soil that is formed by a pruning soil Plate (309) endowed, in its internal higher part, with cleaning Reeds (344) intended to avoid straw losses with cereals outside the header and are installed in the lower protection Plates (308) intended to protect the back along with the lower protection Plate (308-A) to avoid letting the plants or cereals that are being transported by the Snails (312) towards the straw Elevator (302) come out. The lower Frame consists of a great innovation in the harvest Headers system due to its totally innovating system which is composed of mounting, through Longeron (348) which is fixed in the lower part of the hydraulic Pistons (307-A), of the Shoes Set (306) that are manufactured with at least two parts, that is, one frontal Tip (306-A) and one back Part (306), and they are both endowed with connection opening (324 and 323), which will allow for their union by fixing internal pins and the frontal Tip will turn both to the left and to the right, so that we will mount on these Shoes sets, on the frontal Tips (306-A) and in the lower part,

adjustment Plates (310) that will keep direct contact with the terrain, and will automatically adjust the cutting Bar height (350) so that it doesn't maintain contact with the ground, thus, this lower Frame (347), for being fixed in the lower part of the hydraulic Pistons (307-A), will have a floating upwards and downwards following the unlevelling of the terrain without however change the adjustment of the Reel set functioning height (07) regarding the cutting Bar (350) and of the snail Shafts (312) regarding feeding, without the need for the Combine operator to have to stop and make the Header height adjustment when there is a terrain unlevelling.

As shown by the mounting of the lower Frame (347) the Shoes (306) will have in their whole extension some level Plates (306-B) that will be in charge of the level adjustment, so that when the terrain is uneven and its back part touches the hydraulic Piston tip (307-A) the Piston will be driven automatically making the float, that is, the suspension of the whole set over itself, avoiding that the operator has to make the Header height adjustment (06), thus, in the Shoes (306), and more specifically on the frontal Tip (306-A) the cutting Bar will be mounted (350) and it is another functional innovation when it comes to Combine Header, where it will be mounted by complying with the following order: on the front part we will have the cutting razor set (315) and on the back part the mounting of individual Plates (311) with hinges (342) on the for sides. As to this cutting bar, according to the aforesaid, it is a great innovation, considering that its mounting will happen in the whole Header length (06) by the mounting of individual Plates (311) fixed to one another by the sides, through their Hinges (342), so as to have a mounting of straps of individual Plates (311) totally flexible and the side Hinges (342), thus, we have on detail "E" of figure 51 the amplification of the frontal part of a cutting Bar column (350) formed by the seat Guide (338), and the cutting razor (339) will be fixed on the Chain (337) which will work within the channel (351) formed by the higher Guide joint (340) and the Seat Guide (338). The aforesaid Chain (337) will be in charge of providing a continuous come and go side move regarding the cutting Knifes (339), which will enable that it makes the cutting of the branches of the plantation that is being harvested, thus, these devices that form the cutting Razor (315) will be interconnected to the individual Plates (311) through the connection Plate (341)

which will have Hinges (342) only in the sides and in the back part to connect the other individual Plates (311 ) that will form the cutting Bar set (350).

Therefore, the lower Frame (347), duly mounted and installed in the higher Frame (304) that will have a back guide Arch (319), will be fixed in the engagement Support (335) and consequently connected to the straw elevator (302), and this fixing will allow that this harvest Header (06) makes a vertical move due to the pendulum higher Pins (316) that will connect the higher Rod (352) of the higher Frame (304) to the higher Fitting (335) and also by the lower Pin (317) which will be fitted to the back guide Arch (319) and the above mentioned higher Frame (304) will have a security reinforced through its fixing behind the thrust Supports (353).

Likewise, this invention brings an innovation that consists of a functional improvement applied to the straw Elevator (302), considering that all the existing Headers use this Straw Elevator, because it is responsible for receiving the plantations with the cereals cut by the cutting Bar (350) and feeding the internal part of the Combine so that the cereals are threshed, thus, the claim includes this straw Elevator (302) a Sieve (334) that will make the first cleaning of impurities harvested together with the plants, that is, little pieces of earth, etc. besides bringing another innovation that consists of the plants creeping system through the creeping feeders mounting system (332) in diagonal line (D) inserted, considering that the creeping system is only known in straight lines inserted, which causes a disproportional blocking of the plantations creeping steering and a clogging in the Combine entry.

Therefore, in this straw Elevator (302) there is the formation in diagonal line (D) of the creeping feeders (332) to work in an intercalate way, avoiding the accumulation of straws both in the inner part of the Elevator and in the Combine entry, and these Feeders are mounted on Chains (343) and with driving by means of motive power and with hydraulic system for the creeping rotation speed adjustment. The grains and impurities separator Set (02) that is an innovation of this invention is installed right below the thresher Set formed by the cylinder (03) and the Sieves (26 and 29) so as to receive the cereal grains that are

threshed right in the entry of the thresher Cylinder, and to run all the extension of the thresher Set and pass by the front (26) and back (29) Sieves so that its composition begins in a first phase of separation through the mounting of a higher peeling Plates layer (46, 47, 48, 49, 50, 51 and 52) as we can view in figure 10, that is mounted on the adjustment Supports (57) in the internal sides of the side Walls (58) so as to enable the regulation of the peeling Plates in at least six or seven falls, so that, with the vibrating functioning of the separator Set (02), the cereal grains will be separated from the impurities, that is: earth, little stones, little pieces of straw, etc., so that these residues will be falling in a lower Sieve (53) and the cereal grains will fall on the second separation phase through the lower peeling Plate (54). The impurities that fall in the lower Sieve (53) will be filtered by the holes and will fall on the impurities Plate (28), while the cereals that also fall on this sieve (53) will follow, due to its vibrating move, until they fall in the lower peeling Plate (54) so that this is the last step for separation and the clean cereals will finally fall on the draining Plate (55) and will slip directly to the grains Container (09) to be unloaded within the grains Elevator (12) and to be unloaded in the bulk carrier Tank (23) through the unload Pipe (21).

It's important to note that this separator Set is endowed with two air turbines or fans (27) that will be working constantly during the impurity separation process to blow through the peeling Plates and the Sieves so that the pieces of straw or plantation branches that manage to overcome the threshing will get out by the bottom of the separator Set (02) which is open, differently from those existing nowadays, and it's also important to stress that in the lower part of this separator Set (02) we have the retrack draining Plate (56), which on purpose, is manufactures with a extension bigger than the others, providing a size difference (60) that will enable that the combs or pods, with the most resisting cereals that have not been threshed, are drained to the retrack Housing (11) and return by the retrack elevator (30) up to the entry (05) of the Cover (04) passing by the retrack unload Pipe (21 -A), likewise, this separator Set will have back opening, differently from the current machines, which will allow for the exit of the impurities accumulated that will be blown by the action of the air turbine (27).

One important innovation that this invention brings is the fact that the grains Housing (09), of the retrack Housing (11), of the higher

draining Channel (36), of the lower draining Channel (37) and of the unload Pipes (38 and 40) are internally endowed with the grains transport system, through a tracks Set (43) that will work on the guide Rollers (42) in constant circulation provided by motive power, directly on the side Pins (45) which in turn will turn the guide Rollers (42) that due to their format and for the spaced installation of the division Supports (44) on the Track (43) will form little trays that will carry the cereal grains softly, eliminating the traditional system used composed by a Shaft with endless thread, which remains solely in places totally closed and that don't offer risks to the operators for being inside the clean grains unload Pipes (21) and the retrack unload Pipe (21-A) which will internally have an endless thread Shaft (22).

The lower unload Pipe (38) and the higher unload

Pipe (40) will be interconnected by a connector Knee (39) which will be manufactured with internal gear so as to enable its side and frontal upwards and downwards moving in order to enable an easy, quick unload and in any place reached by the higher unload Pipe (40) which will still count, in its exit tip, on unload Guides (41) that in their lower part will have male fittings to receive by fitting other unload Guides (41 ) in order to enable the mounting of as many Guides as one wishes.

The Elevators also present internal transport systems of the grains to avoid spoiling the cereals and enable their transportation up to the unload within the Internal Housing (24) of the bulk carrier Tank (23), considering that these Elevators are formed by a system of Chains (19) that work in a rotating manner through the crowns installed internally, so that in these Chains (19) the Collectors (20) will be fixed and they, for having a cup shape, will eliminate the little spoils caused to the cereal grains as shown in detail "A" amplified in figure 3, in order to improve the quality of the cereals harvested, increasing the production of the internal transport which is also made through endless thread shafts.

The Frame in the figure through the Frame (101) of the frontal suspension Set (102) and the back suspension Set (103) interconnected by sustaining Feeders (142) in both the sides that lie on the sustaining Bars (106) and the back sustaining Bar (128) form the Combine sustaining Frame.

This front Suspension (102) is composed by the sustaining Bars (106) that are fixed by flexible frontal Supports (105) that in turn are

interconnected through the bowing Shaft (118) forming two sets interconnected by the Differential (119) and by the gear Box (117); this Differential (119), in turn, interconnects the steering Boxes (107) through the support Shaft (120).

The steering, mounted in the frontal Suspension Set (102), is equally composed by the steering Boxes (107) and interconnected by the adjustment Boxes (113) that receive the right adjustment Tip (109) and the left adjustment Tip (110), both of them are interconnected by the back steering Cylinder (108), so that these mechanisms will be driven by a steering hydraulic system that will drive, through the frontal cylinder Support (126), the frontal steering Cylinder (112), which interconnects the steering Box (107) through the Tip Cap (111), so that all these devices will drive the transmission shaft Cardan (114) which is protected by the steering box Cover (121), so that, the aforesaid Cardan (114) is in charge of bringing rotation to the frontal wheels cubes (116), which in turn make the front wheels movements to the right and to the left as illustrated in figures 33 and 34. Likewise, the back suspension Set (103) is composed by the back sustaining Bar (128) that lies on the higher back Flexible Support (127), that is in turn connected between the lower back flexible Supports (129) through the back bowing Shaft (115). The Flexible Supports mentioned (129) are fixed in the Longeron (134) that makes the link between the right and left back wheels, besides receiving the double steering Arm (140) in one side and the simple steering Arm (141) in the other side, and in the double steering Arm (140), are fitted in one side the right steering Tip Cap (133) and in the other side the back hydraulic Cylinder (136) and this back hydraulic Cylinder (136) is driven through the double steering Arm (140) by the hydraulic cylinder Tip Cap (135), which is interconnected in the back cylinder Support (125), directly by the operator in the control cabin hydraulic steering command, in the same frontal steering drive system, so that the double steering Arm (140) is fixed to the Longeron (134) through the left shaft Tip (137), while the simple steering Arm (141) is fixed through the right shaft Tip (138) also in the Longeron (134). When driven by the operator, the hydraulic steering system will drive the back cylinder Support (125) which in turn will drive the double steering Arm (140) that will also drive the Shaft and the wheel cube (116) and also

the right steering Tip Cap (133) that, for being interconnected to the back steering Bar (131) will drive, on the other side the left steering Tip Cap (132) and in turn will drive the simple steering Arm (141) that will also drive the Shaft and the wheel cube (116) so as to move the back steering both to the right and to the left, however always in the opposite steering of the frontal wheel motion, that is, when the operator drive the hydraulic steering to the right the front steering will be driven to the right and the back steering will be driven to the left, therefore enabling a convergent move.

The frontal suspension Set (102) will contain the suspension Supports (124) which will receive the Combine Harvest Header and will have the drive hydraulic cylinders (130) that will make the motion upwards and downwards of this harvest Header.

This frontal suspension Set (102) is interconnected to the sustaining Feeders (142) through the side Supports (122) and the hydraulic Cylinders (123), which allows the Suspension vertical bowing, due to the fact that these hydraulic Cylinders (123) work so as to support the bowing felt by the Suspension when there is terrain oscillation.

The Cylinder Cover (04) that contain internally higher Rings (212) that will form, after the mounting, circular channels for the forwarding of the straw mix with cereals, and also a retrack return Opening (05). Likewise, we count of the three stages thresher Cylinder (03) which is manufactured with a conic Tip (202) one frontal pin Shaft (203), one back Cover (204) one back pin Shaft (227) and also maintenance Windows (218); their three thresh phases start by the frontal Wing (205) which will receive the hammers in "L" (206) with the thresher Teeth (207). The second phase of hammers is composed by the thresher Hammers (208) with thresher Finger (208-A) while the third phase of thresher Hammers is formed by lower Wing (209), which will have helicoidally triangular form to receive the back thresher Teeth in its higher part (210).

The sieves Set is formed by sustaining Arches (214) fixed laterally by separators (220) so as to keep structured and able to receive in the first phase the thresh Sieve (26) and in the second phase the thresher Pipes (219) which are fitted in the arches through the holes (219-A) along every sustaining Arch (214) so as to enable the level adjustment of a phase regarding another phase, thus,

the phases comprised in this Sieves set can even be alternated, i.e., it is possible to work with the Sieve (26) in the first or in the second phase by only making the change of the helicoidally Hammers sets in the cylinder (03). The handling of the Arches that form the first or second phase sieve structure are enabled by the introduction of the regulator Arm (219-B) which will be inserted in the adjustments Supports (215) fixed in the head of each sieves set so as to give resistance for the Arches adjustment (214) upwards and downwards, moving the second phase regarding the first one as we can see in figure 44 and in figure 46, or even make the adjustment of the two phases as illustrated in figure 47, enabling a major spacing of the sieves Set regarding the Cylinder (03) both to adjust the type of thresh and to proceed with the maintenance in the Cylinder (03).

The thresher Cylinder (03) manufactured with the conic Tip (202) allows that the caption of the straw mix with the cereals is make always by the front, facilitating the thresh development for having provided a less compact caption and the mounting of three phases of hammers for the thresh allows for a better efficiency of the equipment that will be able to be used for almost types of cereal harvesting, providing a more uniform and efficient thresh. The three Hammers phases are mounted to keep in the same alignment of height and in helicoidally form, that is, in a snail form, which enables that when the straw mix is cached by the front, it passes by the first phase where the "L" hammers will make the first thresh for the most sensitive and ripe grains so the straw mix is made into a ball inside the Sieve (26) and the Cylinder (03) causing a lighter work for the Cylinder and making the less sensitive grains thresh, so that the straw mix with the more resistant or smaller cereals, that have not been threshed until this second phase, will follow to the third phase completing the thresh cycle, where it is made by rubbing friction provided by the thresher Teeth (210) in the thresher Pipes (219) and in the Arches (214) that form a semi-open Sieve that provides the final thresh of the more resistant and smaller grains also completing the general sorting of the cereal grains since their entrance by the Cylinder front until the end of the sieves Set (concave). In addition to improving the Cylinder (3) functioning work, this system will allow for a height and rotation speed adjustment according to the type of grain to be harvested, since it will be driven by motive power and will have

a light work rotation through their frontal pin Shafts (203) and back shaft Pin (227) both fixed in the frontal Feeders (225) and the back Feeder (226).

The maintenance of the aforesaid thresher Cylinder

(03) is also facilitated due to the fact that it's kept by the frontal and Back (227) Shafts respectively in the frontal Feeder (225) and in the back Feeder (226) which allow its unfitting to be easily removed by a creeping carter which will run on the right and left Tracks (221 and 221 -A) in addition to containing the maintenance Windows (218).

There fore this Combine will provide, as mentioned before, an improvement both in the operational use and in its work efficiency and productivity by time worked, so that it will use some of the systems already described of the state-of-the-art claimed by the own inventor so as to obtain a front and back wheel steering system that function in opposite steering, that is, when the front steering points to the right the left steering will point to the left and vice-versa, the Header harvest system in work position in an alignment of the straight ground level (NS) and consequently a working straight angle (AR) and with a left angle turn (AE) regarding the ground level (NS), as well as of a right angle turn (AD) regarding the ground level (NS), besides providing a work position in an unleveled Ground (SD) so that its right Wheel (RD) follows the lower part of the ground while the left Wheel (RE) follows the ground higher part due to the suspension activity provided by the hydraulic Cylinder (64), as well as contrarily the ground unlevelling work so that the unleveled Ground (SD) demands a major lower drive in the left Wheel (RE) and the right Wheel (RD) and follows the higher part of the ground due to the suspension provided by the Hydraulic Cylinder (64). This Combine (01) will have frontal suspension, allied to a frontal wheels steering system that will work in convergence with the back wheel steering and will enable a quicker and more efficient maneuver in less space and obviously will be driven by force Engine (33) will have fuel Tank (34); the bulk carrier Tank will have a higher Cover (35); the Combine frontal Suspension will be possible due to its installation on the Frame with the suspension already mentioned as the estate-of-the-art so that the mounting will occur on the frame Feeder *(59) and on the hydraulic Cylinders (64) with hydraulic Pistons (63) installed on the fixing

Support (62) and in the frame sustaining Bar (65) on the Combine differential Shaft, interconnecting the steering Box (66) of both sides as illustrated in detail "B" amplified in figure 5.

This cereal Combine with such a utility and practicity is sure to be manufactured with size and capacity variations of harvesting to meet all kinds of cereal crops.
