[029] According to what is shown by the above related figures, the "DEVICE INTRODUCED IN AGRICULTURAL MACHINE ", object of this patent application, has its functional system connected to the rotational output of an agricultural tractor, which can be at rear or front side.

[030] Through the couplings and cardans shafts, the rotation for the transmission shaft is directed (3), where it is divided for the right and left sides through the transmission shafts (5) where they command a deflection roller (6) that can to be of 5 and 4 straps (8) according to the kind of equipment (equipment for thinning or heavy cutting 5 straps for light cutting 4 straps), these straps (8) transmit the rotation for other lower deflection rollers (7) also located on each side of the cutting rotor (9) where the effective cutting is processed.

[031] This cutting rotor (9) is manufactured from one pipe (10) CC NBR 5590 GRA 8 "SCH40 (8.7 mm) thickness in length that varies according to the machine size (between 1720 and 2280 mm). Between the ends in an internal diameter, there is a welded flange (1 1) with a diameter of approximately 203 mm, welded for the fixation of the rotor axis.

[032] The rotor axis (12) aims to make the cutting rotor (9) spin providing support to it through the roller; placed in the cube with retainers and lock rings system that allows the functioning with lightness with the aid of grease.

[033] The rotor has two side plates in the shape of flange (23) with a diameter of approximately 540 mm and 450 mm and thicknesses of 12.7 and 9.5 approximately, correspondents. [034] The rotors have a system with cutting semi-rotors for providing the equipment balancing, in quantities of 16 to 12 parts, according to the size of the rotor, with thickness of 9.5 to 12.7, according to the size and use of equipment if for light line or heavy line (aligned to two rods in round steel inlaid on the sides and in each semi-rotor).

[035] The cutting rotor (9) has a system where one support of knife is used, on which the cutting knives (15) are placed in line by a square rod (16) also inlaid on the sides and in each support, whose sizes and quantities vary according to each equipment model. All of them are affixed with two screws in each knife (15).

[036] The knives (15) have one cutting angle of approximately 35 degrees.

[037] To ensure the alignment with the support system and a right sharpening that guarantees right cutting while keeping the balancing of the rotor system.

[038] The equipment also has two arm in "L" (21) and the third one denominated as the third point composed by a frame in“U” shape, one hood in steel thickness 6,35 mm, where the eyebolts and the arms are placed for supporting and for the work of the whole equipment.

[039] A system of antecedent arms background allows the shrubs, pens and trees of medium sized to lean for the grinder to do its job.

[040] For safety on the released debris by the rotor, chains curtain (24) in joints 8 mm in length and about 350 mm, prevents the debris danger.

[041] More exactly, the agricultural machine (1), object of this patent application is composed by a horizontalized chassis (2), which has at the center of its upper side a transmission shaft (3), which has an input axis (4) on the front side, which receives movement and torque for power receiving from the tractor and two output axes, one on each side, in which the transmission axes are connected (5), to whose ends deflection rollers are coupled (6), to which lower deflection rollers are connected (7) through straps (8). [042] The referred lower deflection rollers (7) are connected at the ends of a cutting rotor (9), which is placed at lower side of the chassis (2).

[043] The referred cutting rotor (9) is composed from a pipe (10), which has on each end one internal flange (11 ), from which an axis is placed (12), from its center where the referred lower deflection roller is connected (7).

[044] At the cutting rotor (9) two sets of linear knives have been planned (14), diametrically opposites, where each set of linear knife (14) is comprised by multiple knives (15) fixed on one rod (16) of a quadrangular transversal section, whose ends are coupled to external flanges (23); which are placed at 90 ° from the linear knives (14) rods of circular transversal section are planned (17), whose ends are coupled to external flanges (23) and throughout their length have multiple semi-disks (18), which are connected to the pipe (10) and to the rods (16).

[045] The axis (12) is coupled to chassis (2) through a bearing support (13) and the set of deflection rollers and straps are protected by fairings (19) that have lids (20).

[046] Above the chassis and at the ends two arms have been planned in "L" shape (21), opposed and at the center, a frame of "U" shape (22).

[047] At the top of chassis there is a chains curtain (24) and below, on each end there is a support base (25) sort of ski.

[048] The frontal system prevents the tractor operator to drive while the equipment is in a rear position, which is an operational discomfort for a normal working system. At the same time, it increases and optimizes the productivity of the equipment, managing to work out more hectares at the end of the day.

[049] It is a completely new product, it can clean in a short time many hundreds or thousands of hectares, pens, bush, plantations of tea, coffee, orange, cleaning electrical transmission lines with maximum safety for the workers and high productivity and Yield.

[050] From the description provided above, it can be verified that the referred "DEVICE INTRODUCED IN AGRICULTURAL MACHINE " is characterized as an equipment of great utility, having all practical and functionality qualities that fully justify the patent application of a Utility Model.

[051] The rotor is composed by six - 6 - nozzle or hammer lines and twelve - 12 - cutting lines, half of the nozzles are forwarded and the other half are delayed. The cutting lines are, therefore, alternated. The number of nozzles are proportional to the model and machine dimension (it might have 48, 54 and 66)

Advantages and Competitive Advantages of this Rotor
