2. Description of the Prior Art Traditionally, persons have sought to remove sediments and debris from soggy ground or wetlands for a variety of reasons; the objects removed have been rocks, trash, sediments, or excess vegetation. The method used for removing the debris has been to have workers or a mechanical hoe move through the area in question and dig up the sediments and debris and place the sediments and debris in a truck. When filled, the truck was driven to a dump or base station and emptied. The traditional methods have many draw backs, the most prominent of which is that trucks are not specifically designed to move over soggy ground or wetlands. Further trucks require a driver and persons to stand on the truck bed and receive the debris, if collected by hand.

Accordingly, effort has been expended to improve this system.

Such a device is disclosed in US Patent No. 4,363,725 issued to Morita et al. Morita et al. disclose a self propelled apparatus that is used to remove stone and gravel from excavated soil.

This device consists of a first conveyor belt, which guides the excavated soil and gravel to the sieving area, and a second conveyor which aids in the transportation of the soil and gravel through the sieving mechanism. This device, though efficient in removing stone and gravel from excavated soil, does suffer some drawbacks. The combination of sieve mechanism, a first conveyor and a second conveyor provides for an apparatus that is bulky, difficult to maneuver, and expensive to operate. Additionally, this apparatus is not designed nor configured to travel through wetlands or the like.

Another device is disclosed in US Patent No. 4,590,739 issued to Abatti et al. Abatti et al. disclose a self propelled crop harvester which includes wing conveyors. The wing conveyors received the picked crop (i. e. melons, squash, or the like) and transport these items to a processing area. Though efficient, this harvester does include some shortcomings. The apparatus disclosed still requires individuals to pick up the crop and load the items onto the wing conveyor.

This task is time consuming and is also strenuous on the individual. Further, Abatti et al. utilizes trucks or the like, thereby providing for a device that is not applicable for wetlands or the like. In addition, Abatti et al. provides for an apparatus that requires the use of several employees, including at least one driver for the truck, or the like, in order to successfully employ the apparatus.

Another device is disclosed in US Patent No 4,965,993 issued to Butler et al. which discloses a crop harvester for vine crops. The harvester includes an operator station and a conveyor belt that is adapted to receive and transport the vine crops. This harvester further includes vine cutters that are anchored to caster wheels. The design and configuration of the harvesters disclosed in Bultler et al. provides for a device that is not versatile, and as such, cannot be utilized in wet ground.

As seen, none of these previous efforts provide the benefits intended with the present invention. Additionally, prior techniques do not suggest the present inventive combination of component elements as disclosed and claimed herein. The present invention achieves its intended purposes, objectives and advantages over the prior art device through a new, useful and unobvious combination of components which are simple to use, utilizes a minimum number of functioning parts, at a reasonable cost to manufacture, assemble, and by employing only readily available materials.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As illustrated through the various views of the drawings (figs 1-8), the self propelled conveyor device 20 of the present invention comprises a support frame 9 and a conveyor belt system 22.

As illustrated in figures 1,2,4,7, and 8 the support frame 9 is provided with endless tracks 10 which allow the device 20 to be self-propelled. The endless tracks 10 can include treads or cleats in order to provide for a multi-terrain device which can adequately be utilized in any environment, including wet or boggy ground.

The endless tracks engage rollers 24 (illustrated in figures 1,4, and 7, but labeled only in figure 7). These rollers 24 are powered via a first motor (not illustrated). This will enable the device 20 to move in a desired direction once the rollers 24 are rotating, inherently causing the endless track 10 to rotate. This motor is powered by the power unit 14 which is mounted on the support frame 9. This power unit 14 is a hydraulic system and includes a pump that is power via a second motor. This second motor can be a diesel, gasoline, or electrically operated motor.

The support frame 9, illustrated in figs. 1 and 2, is located between the endless tracks 10.

This support frame 9 maintains the transport assembly. The transport assembly enables the vertical, horizontal, angular, and rotational movement of the conveyor belt assembly 22.

Secured above the frame 9 and between the endless track 10 is the conveyor belt assembly 22. The conveyor belt assembly 22, as seen in figs. 1, 2,4 and 6a-8, includes a conveyor frame 3.

Located in the proximity of the front end or delivery end of the conveyor frame 3 is a first or header roller 2a, while located in the proximity of the back end or receiving end of the conveyor frame 3 is a second roller or footer roller 2b.

A standard conveyor belt 26 extends around the header roller 2a and the footer roller 2b.

This conveyor belt 26 can be fabricated from a mesh material, so as to provide for a conveyor that includes a plurality of perforations. This will enable the desired material, i. e. water, to escape while enabling the non-desired material (material to be collected), i. e. debris or the like, to remain on the conveyor. It is noted that the sized and shape of the perforations, if used, can be designed so as to conformed to the particular item to be removed.

The rollers (2a, 2b) are controlled and powered by the conveyor belt drive assembly 19.

This conveyor belt drive assembly 19 includes a third motor and a gear box. Hence, the activation of the third motor will provide for the activation of the first and second rollers 2a and 2b, respectively, via the drive belt. The use of the gear box will enable the motor to step up or to step down, when necessary, in order to provide for an adequate amount of torque for enabling the transportation of items regardless of weight and size. This conveyor belt drive assembly 19 is powered via the power unit 14.

Extending outwardly from the conveyor frame 3 are a plurality of evenly spaced and laterally aligned rollers 4. These rollers 4 are used to assist the relocation or repositioning of the conveyor assembly 22. Secured to the conveyor frame 3 and in the proximity of the back end of the frame 3 is a loading hopper 1. This loading hopper 1 extends upwardly from the conveyor frame 3 and will permit the loading of the material onto the belt 26. As seen in fig. 1, the loading hopper 1 can includes an access door 29 which is located on one of the side walls of the hopper.

This access door 29 will enable the user an easier means of depositing items onto the assembly.

As illustrated in fig. 1, the access door 29 is hingedly secured to the side wall of the hopper.

Located above the upper surface of the support frame 9 is the turntable plate 8. This turntable plate is designed to rotate. This turntable plate is illustrated in further detail in figures 2 and 3a-3d. As shown, attached to the upper surface of the turntable plate 8 via bearings 7 is a sun gear 30. Hydraulic cylinders 31 engage the teeth of the sun gear 30 inherently causing the turntable plate to rotate. This will provide for the sun gear 30 and the cylinders 31 to act as the turntable plate actuator 11. This will provide for the conveyor system 22 to rotate.

A plurality of clamps 16 are used to assists in maintaining the turntable plate 8 on the support frame 9. Anti-friction pads 17 are located between the turntable plate 8 and the clamps 16 in order to provide protection to the plate 8 and clamps 16 and can also be utilized as a damper in order to absorb vibrations of the device 20.

Attached to the lower surface of the conveyor frame 3 is a hitch assembly 6. This hitch assembly, seen in figs. 1-5 and 8, will enable the conveyor assembly 22 to be adjusted to a desired position or location. Accordingly, the hitch assembly 6 is part of the transport assembly and is also designed and configured to maintain the conveyor assembly 22.

A lateral slide frame 13 is secured to the hitch 6 via an extension 32. This extension, once secured, is considered a component of the hitch assembly 6. As seen in figs. 1,2,4 and 8, the lateral slide frame 13 further includes a receiving means 28 that is adapted to receive and maintain guide rollers 4. Affixed to the lateral guide frame and the turntable hold down clamp 16 are hydraulic cylinders 5. These hydraulic cylinders 5 are used for the adjustment of the tilt angle of the conveyor assembly 22. A leveling switch is used to level the assembly, thereby providing a means of raising the height while enabling the conveyor assembly to remain in a horizontal position with respect to the ground.

Horizontally secured on the lateral slide frame 13 are horizontal hydraulic cylinders 18.

These horizontal hydraulic cylinders 18 are used to adjust the horizontal positioning of the conveyor assembly 22. As seen in figure 1, the horizontal hydraulic cylinders 18 include opposite ends. The first end is secured to the conveyor the front end 2a of the conveyor frame 3. The second end of the horizontal hydraulic cylinder is secured to the lateral slide frame 13. Once the horizontal hydraulic cylinders are activated, the rollers 4 roll within the receiving means 28. The combination of the horizontal cylinders, rollers, and receiving means allows for smooth horizontal displacement.

It is noted that the combination of the hitch 6, turntable assembly, hydraulic cylinders 5, horizontal cylinders 18, and lateral slide frame 13 provide for the transport assembly.

The device can be controlled and operated via a remote control panel device 15. This remote control panel 15 device may be connected to the device 20 by way of a cable 33. By utilizing a remote control panel device 15 will eliminate the need to use a driver for operating the apparatus 20.

For utilizing the device, a user or operator would activate the device via the remote control panel device 20. This enables the device to be transported to a desired location or designation via the endless tracks 10. These endless tracks 10 move once the rollers are rotating.

Once the device 20 is at a desired location, adjustments can be done to the conveyor assembly 22.

This adjustment will permit for the conveyor assembly 22 to be lifted, lowered, tilted, rotated, or horizontally adjusted via the transport assembly as defined above.

Once adjusted, the conveyor assembly is activated to provide for continuous movement of the conveyor belt. This will permit for the optimum utilization of the apparatus of the present invention 20. The undesired items will be loaded into the hopper 1 to permit for its transportation from the location of the footer roller to the header roller, and then to the desired location for removal and dumping.

While the invention has been particularly shown and described with reference to an embodiment thereof, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention.
