[0037] Example, refer to Figures 1-4This invention provides an embodiment of an automatic unloading machine for recycling residual film, stubble, and weeds. The machine includes a frame 1, a front plowshare 2, front harrow teeth 3, and rear harrow teeth 4. The upper end of the front plowshare 2 is mounted on the frame 1. There are multiple front plowshares 2, all arranged in a left-right direction. The front end of the front harrow teeth 3 is mounted on the frame 1, and the rear end of the front harrow teeth 3 bends downward and extends behind the front plowshare 2. There are multiple front harrow teeth 3, all arranged in a left-right direction. The front end of the rear harrow teeth 4 is mounted on the frame 1, located between the front and rear ends of the front harrow teeth 3. The rear end of the rear harrow teeth 4 bends downward and extends behind the rear end of the front harrow teeth 3. There are multiple rear harrow teeth 4, all arranged in a left-right direction and staggered with the front harrow teeth 3.

[0038] In this embodiment, the recycling machine is installed at the rear of a tractor. The tractor drives the recycling machine forward, and the front plowshare 2 performs preliminary soil breaking operations, preparing for subsequent removal of plastic film, stubble, and weeds. The front harrow teeth 3 can initially harrow and clear residual plastic film, stubble, and weeds in the broken soil, loosening them and moving them forward. The rear harrow teeth 4 further harrow the soil, working in conjunction with the front harrow teeth 3 to improve the removal of residual plastic film, stubble, and weeds, ensuring a more thorough cleanup. The synergistic effect of multiple front plowshares 2, front harrow teeth 3, and rear harrow teeth 4 can effectively remove most of the residual plastic film from the soil, reducing the amount of residual plastic film in the field, thereby reducing the adverse effects of plastic film on the ecological environment, such as reducing soil pollution, maintaining soil aeration and water permeability, and preventing the accumulation of plastic film over the years from affecting crop yields, creating a good soil environment for crop growth. The raking action of the front harrow teeth 3 and the rear harrow teeth 4 can loosen the underground stubble and pull it out of the soil, solving the problem that the underground stubble cannot be removed and affects spring sowing. This provides clean soil conditions for spring sowing, which is conducive to seed germination and growth. It can improve the emergence rate and growth quality of crops, reduce damage to sowing equipment caused by stubble, and reduce agricultural production and maintenance costs.

[0039] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it also includes a rear breaking plowshare 5. The upper end of the rear breaking plowshare 5 is mounted on the frame 1 and is located between the rear end of the front harrow teeth 3 and the front breaking plowshare 2. There are multiple rear breaking plowshares 5, all arranged in a left-right direction and staggered with the front breaking plowshare 2. After the front breaking plowshare 2 performs the initial soil breaking operation, the rear breaking plowshare 5 performs the breaking operation again, which can improve the soil breaking effect. Moreover, the staggered arrangement of the rear breaking plowshare 5 and the front breaking plowshare 2 can increase the soil breaking range.

[0040] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it also includes a push-pull drive mechanism 6, a push-pull main rod 7, a front positioning beam 8, a rear positioning beam 9, a front push-pull rod 10, and a rear push-pull rod 11. The front end of the push-pull drive mechanism 6 is hinged to the frame 1; the front end of the push-pull main rod 7 is hinged to the rear end of the push-pull drive mechanism 6; the front positioning beam 8 is located below the push-pull main rod 7, and the length direction of the front positioning beam 8 is set along the left-right direction. The front positioning beam 8 is hinged to the frame 1, and the front ends of all the front rake teeth 3 are set on the front positioning beam 8; the rear... The positioning beam 9 is located below the push-pull main rod 7 and behind the front positioning beam 8. The length direction of the rear positioning beam 9 is set along the left and right direction. The rear positioning beam 9 is hinged to the frame 1. The front ends of all the rear rake teeth 4 are set on the rear positioning beam 9. The upper end of the front push-pull rod 10 is hinged to the middle of the push-pull main rod 7, and the lower end of the front push-pull rod 10 is connected to the front positioning beam 8. The upper end of the rear push-pull rod 11 is hinged to the rear end of the push-pull main rod 7, and the lower end of the rear push-pull rod 11 is hinged to the rear positioning beam 9.

[0041] Both the front positioning beam 8 and the rear positioning beam 9 are hinged to the frame 1 via hinges. The hinge axis of the hinges is set in the left-right direction. The hinge between the front positioning beam 8 and the frame 1 is located in front of the front positioning beam 8, and the hinge between the rear positioning beam 9 and the frame 1 is located in front of the rear positioning beam 9. When raking is required, the push-pull drive mechanism 6 extends, pushing the push-pull main rod 7 backward. The push-pull main rod 7 lowers the rear ends of all the front harrow teeth 3 to the ground via the front positioning beam 8, and simultaneously lowers the rear ends of all the rear harrow teeth 4 to the ground via the rear positioning beam 9. The tractor drives the recovery machine forward, and the front breaking plowshare 2 performs preliminary soil breaking operations. The front harrow teeth 3 and rear harrow teeth 4 rake the remaining plastic film, stubble, and weeds in the broken soil. After reaching the designated position, the tractor stops moving, the push-pull drive mechanism 6 retracts, and pulls the push-pull main rod 7 forward. The push-pull main rod 7 lifts the rear ends of all the front harrow teeth 3 via the front positioning beam 8, and simultaneously lifts the rear ends of all the rear harrow teeth 4 via the rear positioning beam 9, so that the plastic film, stubble, and weeds rake by the front harrow teeth 3 and rear harrow teeth 4 are separated from the front harrow teeth 3 and rear harrow teeth 4 and fall off for easy centralized processing. When raking is needed again, the push-pull drive mechanism 6 extends again, causing the rear ends of the front harrow teeth 3 and the rear harrow teeth 4 to fall back onto the ground, allowing the tractor to drive the recycling machine forward again. Compared to manually separating the plastic film, stubble, and weeds from the front harrow teeth 3 and the rear harrow teeth 4, mechanized automatic unloading saves more time and labor.

[0042] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it also includes a support rod 12, the lower end of which is mounted on the frame 1, and the front end of the push-pull drive mechanism 6 is hinged to the upper end of the support rod 12. The support rod 12 can provide a stable support point for the push-pull drive mechanism 6. Compared with directly hinged to the frame 1, this invention, by setting the support rod 12, can reduce the extension length of the push-pull drive mechanism 6, reduce the stroke requirement of the push-pull drive mechanism 6, and save costs.

[0043] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it also includes a reinforcing rod 13. The front end of the reinforcing rod 13 is connected to the support rod 12, and the rear end of the reinforcing rod 13 is inclined downward and connected to the frame 1. The reinforcing rod 13, the support rod 12, and the frame 1 form a stable triangular structure, which can effectively prevent the support rod 12 from deforming or being damaged due to excessive force during operation. It can further enhance the stability and reliability of the support rod 12 and the entire frame 1, making the recycling machine more stable during operation, reducing vibration and shaking, and improving the cleaning effect.

[0044] Furthermore, such as Figure 5 As shown, it also includes a front pressure plate 14, which is arranged along the left-right direction along its length. The front pressure plate 14 is positioned above the front positioning beam 8 and forms a detachable connection with the front positioning beam 8. The front pressure plate 14 has a front receiving groove 15, and the front end of the front rake tooth 3 is inserted into the front receiving groove 15 and clamped between the front pressure plate 14 and the front positioning beam 8. The front pressure plate 14 can be locked to the front positioning beam 8 with bolts, pressing the front rake tooth 3 onto the front positioning beam 8. This ensures that the front rake tooth 3 is firmly fixed to the front positioning beam 8 during operation, preventing loosening or falling off, thus improving the cleaning effect. Furthermore, when the front rake tooth 3 is damaged, it can be easily disassembled and installed, facilitating maintenance and replacement, and reducing equipment maintenance costs.

[0045] Furthermore, such as Figure 5 As shown, there are multiple front pressure plates 14, all arranged in a left-right direction. Each front pressure plate 14 has at least two front receiving slots 15, and all the front receiving slots 15 are arranged in a left-right direction. In this invention, each front pressure plate 14 has three front receiving slots 15 arranged in a left-right direction. Installing one front pressure plate 14 can fix three front rake teeth 3, making installation simpler and more convenient. Moreover, when a front rake tooth 3 is damaged, only the corresponding front pressure plate 14 needs to be removed and the front rake tooth 3 replaced, without affecting other front rake teeth 3 and front pressure plates 14, thus improving work efficiency. In addition, by changing the number of front rake teeth 3 on each front pressure plate 14, the spacing between two adjacent front rake teeth 3 can be adjusted to adapt to different cleaning needs.

[0046] Furthermore, such as Figure 5 As shown, it also includes a rear pressure plate 16, which is arranged along the left-right direction along its length. The rear pressure plate 16 is positioned above the rear positioning beam 9 and forms a detachable connection with the rear positioning beam 9. The rear pressure plate 16 has a rear receiving groove 17, and the front end of the rear rake teeth 4 is inserted into the rear receiving groove 17 and clamped between the rear pressure plate 16 and the rear positioning beam 9. The rear pressure plate 16 can be locked to the rear positioning beam 9 with bolts, thereby pressing the rear rake teeth 4 onto the rear positioning beam 9. This ensures that the rear rake teeth 4 are firmly fixed to the rear positioning beam 9 during operation, preventing loosening or falling off, thus improving the cleaning effect. Moreover, when the rear rake teeth 4 are damaged, they can be easily disassembled and installed, facilitating maintenance and replacement, and reducing equipment maintenance costs.

[0047] Furthermore, such as Figure 5 As shown, there are multiple rear pressure plates 16, all arranged in a left-right direction. Each rear pressure plate 16 has at least two rear receiving slots 17, and all the rear receiving slots 17 are arranged in a left-right direction. In this invention, each rear pressure plate 16 has three rear receiving slots 17 arranged in a left-right direction. Installing one rear pressure plate 16 can fix three rear rake teeth 4, making installation simpler and more convenient. Moreover, when a rear rake tooth 4 is damaged, only the corresponding rear pressure plate 16 needs to be removed and the rear rake tooth 4 replaced, without affecting the other rear rake teeth 4 and rear pressure plates 16, thus improving work efficiency. In addition, by changing the number of rear rake teeth 4 on each rear pressure plate 16, the spacing between two adjacent rear rake teeth 4 can be adjusted to adapt to different cleaning needs.

[0048] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it also includes a traction plate 18, which is located at the front end of the frame 1 and has a connection hole 19. Bolts are installed at the connection hole 19, and the traction plate 18 is connected to a tractor or other traction equipment by the cooperation of bolts and nuts, thereby connecting the recycling machine to the traction equipment, realizing the traction and movement of the recycling machine. The structure is simple, the connection is firm and reliable, and the disassembly and assembly are convenient and quick, saving time and effort.
