Description

Technical Field

[0001] This application relates to the field of pickup machine technology, specifically a forced-feed residual film pickup machine. Background Technology

[0002] Forced-feed residual film collectors are agricultural machines that collect waste film residue from the surface and shallow soil layers in farmland, then "feed" it into collection bins or other collection mechanisms via a conveying device, thus achieving efficient recycling of residual film. Mulching is an effective means and measure to increase yield and efficiency for many crops and has been widely used in agricultural production for many years. Because different crops often have different agronomic requirements, mechanized collection operations place varying demands on the adaptability of the machinery.

[0003] However, in recent years, while we have developed a corn stubble residue pickup machine, this model has encountered a problem with soil accumulation when picking up mulched crops such as cucurbits. Large amounts of straw, weeds, and soil clods accumulate in front of the machine, preventing it from operating properly. To solve this problem, our company, based on the working conditions of mulched crops such as cucurbits, vegetables, and corn in northern regions, has developed a forced-feed residue pickup machine. Because the straw is quite tall at harvest, this planting pattern is widespread and covers a large area. When using a residue pickup machine, soil accumulation is very likely to occur, causing conventional residue pickup machines to malfunction.

[0004] Therefore, it is necessary to provide a forced-feed residual film pickup machine to solve the above problems. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a forced-feed residual film pickup machine that can quickly clean up straw and other debris.

[0007] Furthermore, the main frame is equipped with an lifting chain conveyor, which is similar to the working mode of a belt conveyor. The lifting chain conveyor has gaps, and a telescopic toothed film winding assembly is installed at the end of the main frame away from the feed roller. The lifting chain conveyor can temporarily hold straw and debris that are crushed and rolled by the feed roller.

[0008] Furthermore, a film winding assembly frame is provided on the main frame near the telescopic toothed film winding assembly. A tilting hydraulic cylinder is fixedly installed on the input end of the film winding assembly frame. The tilting hydraulic cylinder is positioned on the main frame. The film winding assembly frame can perform a tilting movement. A telescopic toothed control oil pipe is fixedly installed on the film winding assembly frame.

[0009] Furthermore, a gearbox is fixedly installed on the main frame. The gearbox can transmit torque from the tractor's rear output shaft to itself. In addition to ensuring the transmission function of the pickup assembly, the gearbox can also drive the telescopic toothed film roll assembly.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] like Figures 1-3 As shown, this application provides a forced-feed residual film collection machine, including a collection machine assembly 10. The collection machine assembly 10 is used to collect waste residual film from the surface and shallow soil layer in farmland, and then "feed" into the collection machine assembly 10 through a conveying device, thereby achieving efficient recycling of residual film. The collection machine assembly 10 is powered by a four-wheel tractor during transportation and adopts a three-point suspension connection method, which can quickly connect or disconnect the collection machine assembly 10 from the external tractor, improving the efficiency of work preparation and conversion.

[0023] Furthermore, when transporting the pickup assembly 10, the pickup assembly 10 can be lifted for transport by the hydraulic system of the tractor. On the one hand, this increases the height of the pickup assembly 10 off the ground, preventing damage caused by friction and collision between the components of the pickup assembly 10 and the ground during transportation, and also reducing the impact on the road surface. On the other hand, the raised pickup assembly 10 reduces the resistance during travel, making it easier for the tractor to pull, and making the transportation process safer and smoother.

[0024] During operation, the pickup assembly 10 is lowered via the hydraulic control of the tractor, allowing it to contact the ground and move forward. The pickup assembly 10 includes a main frame 11 with several sets of moving wheels 18 mounted on bearings. These wheels 18 can contact the ground. A hydraulic motor 26 is mounted on the main frame 11 and can be driven by the external tractor hydraulic system. A feed roller 25 is mounted on one end of the main frame 11, and the input end of the feed roller 25 is connected to the output end of the hydraulic motor 26, allowing the feed roller 25 to rotate via the hydraulic motor 26. The surface of the feed roller 25 can be fitted with a specially designed rake tooth structure, which can hook up and gather residual film on the ground during rotation.

[0025] Furthermore, several sets of toothed film-lifting shovels 27 are fixedly installed at the bottom of one end of the main frame 11. These film-lifting shovels 27 can be placed in the soil. When the entire pickup assembly 10 moves forward via the moving wheels 18, the film-lifting shovels 27 will move synchronously on the land. When the film-lifting shovels 27 enter the soil and move with it, the soil layer containing straw, weeds, waste film and other debris will be shoveled up and will pass over the rotating feed roller 25. Since the feed roller 25 is equipped with a specially designed rake tooth structure, the feed roller 25 can perform preliminary sorting and separation of debris during rotation.

[0026] The main frame 11 is equipped with a lifting chain conveyor 13, which is similar to a belt conveyor. The lifting chain conveyor 13 has gaps, and a telescopic toothed film winding assembly 16 is installed at the end of the main frame 11 away from the feeding roller 25. Straw and other debris are crushed and rolled by the feeding roller 25 and then conveyed to the lifting chain conveyor 13. Under the action of the lifting chain conveyor 13, some soil falls and separates using its gaps, while straw and waste film are conveyed to the telescopic toothed film winding assembly 16 for collection and then wound onto the telescopic toothed film winding assembly 16. The straw is thrown out, and the waste film is wound on the film winding shaft of the telescopic toothed film winding assembly 16. The telescopic toothed film winding assembly 16 can further collect or process these debris.

[0027] The main frame 11 is equipped with a film winding assembly frame 14 near the telescopic toothed film winding assembly 16. A tilting hydraulic cylinder 15 is fixedly installed on the input end of the film winding assembly frame 14. This tilting hydraulic cylinder 15 is positioned on the main frame 11. After the pickup assembly 10 has worked on a certain area of ​​land, the waste film on the film winding shaft of the telescopic toothed film winding assembly 16 needs to be unloaded. This requires controlling the tilting hydraulic cylinder 15 via the external tractor hydraulic system, enabling the film winding assembly frame 14 to tilt. The entire telescopic toothed film winding assembly 16 is rotated from a horizontal state to a vertical state. The telescopic toothed control oil pipe 17 is fixedly installed on the frame 14 of the film winding assembly. The telescopic toothed control oil pipe 17 transmits hydraulic oil through the oil pipe and uses the hydraulic principle to realize the extension and retraction action. Thus, the telescopic toothed film winding assembly 16 can rotate continuously. During operation, film can be wrapped. In the unwrapping state, the waste film wrapped on the telescopic toothed film winding assembly 16 can be detached under the action of gravity and centrifugal force to achieve the film unloading effect.

[0028] The main frame 11 is fixedly equipped with a gearbox 12, which can transmit torque from the tractor's rear output shaft to itself. In addition to ensuring the transmission function of the pickup assembly 10, the gearbox 12 can also drive the telescopic toothed film winding assembly 16. When the gearbox 12 transmits torque to the telescopic toothed film winding assembly 16, it can operate in a set manner, such as the telescopic toothed film winding assembly 16 rotating to wind and collect the processed residual film, thereby completing the entire residual film pickup process. The pickup assembly 10 is controlled by the tractor's hydraulic system, which can effectively crush and roll straw, weeds and other foreign objects. When there are small pieces, the pickup assembly 10 can also float.

[0029] Both ends of the main frame 11 are fixedly installed with connecting blocks 22, and small holes are opened on the connecting blocks 22. The connecting blocks 22 are installed with push rods 21 through the small holes, and springs 23 are installed on the film-lifting shovel 27. The springs 23 are fixedly connected to the connecting blocks 22. The springs 23 can continuously and elastically push the film-lifting shovel 27 out, while the film-lifting shovel 27 is also tilted downward. Through this elastic design, when the film-lifting shovel 27 encounters greater resistance in the soil, such as hitting hard soil clods or stones, the elasticity of the springs 23 can play a buffering role, avoiding damage to the film-lifting shovel 27 due to rigid collision and extending its service life. At the same time, the elastic pushing out keeps the film-lifting shovel 27 always exerting a certain force on the soil, which can more effectively insert into the soil and scoop up soil layers containing straw, weeds, waste film and other debris.

[0030] Meanwhile, connecting rods 24 are fixedly installed at both ends of the main frame 11. Bearing blocks 241 are installed on the bearings of the connecting rods 24. The feed roller 25 can be located on the connecting rods 24 and the bearing blocks 241. The connecting rods 24 can provide a stable support structure for the operation of the feed roller 25. The bearing blocks 241 installed on the bearings can reduce the friction of the feed roller 25 during operation, thereby ensuring the efficient rotation of the feed roller 25. The teeth on the feed roller 25 can improve friction and effectively crush straw and other debris.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
