DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 2 - Figure 4 The utility model provides an embodiment of an air suction type residual film recovery device, comprising an air bin 1, a positioning plate 2 is fixedly connected to the interior of the air bin 1, an air suction component is arranged inside the air bin 1, a collecting plate 3 is slidably connected to the inner wall of the positioning plate 2, a mounting plate 4 is fixedly connected to the top of the collecting plate 3, a special-shaped connecting block 5 is fixedly connected to the upper surface of the air bin 1, a fixing rod 7 is fixedly connected to the interior of the special-shaped connecting block 5, an L-shaped clamping block 6 is rotatably connected to the outer wall of the fixing rod 7, a torsion spring 8 is sleeved on the outer wall of the fixing rod 7, one end of the torsion spring 8 is fixedly connected to the inner wall of the special-shaped connecting block 5, the other end of the torsion spring 8 is fixedly connected to the interior of the L-shaped clamping block 6, a screw 9 is threadedly connected to the interior of the special-shaped connecting block 5, one end of the screw 9 is fixedly connected to a limiting block 10, and the limiting block 10 is arranged inside the special-shaped connecting block 5;

[0027] Specifically, first operate the L-shaped block 6 and pull the L-shaped block 6 to both sides to reverse the torsion spring 8. The torsion spring 8 is deformed when the L-shaped block 6 is pulled. Next, align the collecting plate 3 with the preset through hole on the top of the wind bin 1 and insert it. During this process, the collecting plate 3 needs to be accurately guided to the inner wall of the positioning plate 2 to ensure that the collecting plate 3 can be accurately placed in the correct position of the wind bin 1. Once the collecting plate 3 is completely moved to the inside of the wind bin 1, release the L-shaped block 6. At this time, due to the absence of external force, the torsion spring 8 begins to release and rotates, driving the L-shaped block 6 to be stuck on the top of the mounting plate 4, thereby fixing the collecting plate 3. In order to ensure the stability of the collecting plate 3 And safety, by driving the screw rod 9 to rotate inside the special-shaped connecting block 5, the rotation of the screw rod 9 will drive the limit block 10 to press against one side of the L-shaped block 6, which can prevent the L-shaped block 6 and the aggregate plate 3 from moving at will. When it is necessary to remove the aggregate plate 3 or the residual film on the outer wall of the aggregate plate 3, the limit block 10 can be pulled back by rotating the screw rod 9 in the opposite direction, so that the L-shaped block 6 is no longer fixed by the limit block 10 and can be pulled again. After pulling the L-shaped block 6, the aggregate plate 3 and the residual film on the outer wall of the aggregate plate 3 can be taken out together through the mounting plate 4, thereby realizing quick and easy installation and disassembly of the aggregate plate 3, and also achieving the effect of collecting and recycling the residual film, thereby improving work efficiency and resource utilization.

[0028] Reference Figure 1 and Figure 5 The air suction component includes a fan 11, the outer wall of the fan 11 is fixedly connected to the inside of the wind bin 1, a plurality of exhaust holes 13 are opened inside the wind bin 1, a filter screen 12 is fixedly connected to the inner wall of the wind bin 1, and a feeding bin 14 is fixedly connected to the outer wall of the wind bin 1;

[0029] Specifically, when the fan 11 is driven to start working, it will absorb air from the external environment through the feeding bin 14. In this process, the strong suction force of the fan 11 not only inhales air, but also brings in the surrounding residual film. Driven by the airflow, the residual film will naturally adhere to the outer wall of the aggregate plate 3. As time goes by, the residual film on the aggregate plate 3 will gradually accumulate. When the mixture of air and residual film enters the internal system through the feeding bin 14, it first encounters the filter 12. The filter 12 captures and isolates various debris in the air, such as dust, particles, etc., thereby ensuring that the fan 11 can operate continuously and stably to avoid damage and malfunctions caused by the entry of debris. After being purified by the filter 12, the pure air will continue to flow and finally be discharged through the exhaust hole 13. In this process, the design of the exhaust hole 13 ensures that the air can flow out smoothly and avoids any obstruction and accumulation, which not only realizes the effective collection and cleaning of the residual film, but also ensures the safe and stable operation of the fan 11.

[0030] Reference Figure 1 and Figure 6 The feeding bin 14 is fixedly connected with a motor 15, the output end of the motor 15 is fixedly connected with a rotating rod 16, the outer wall of the rotating rod 16 is fixedly connected with a plurality of blades 17, the outer wall of the rotating rod 16 is fixedly connected with a cam 18, the outer wall of the cam 18 is provided with a transmission belt 19, the inner wall of the transmission belt 19 is provided with a cam 20, the transmission belt 19 and the cam 20 are both arranged inside the feeding bin 14, the cam 20 is fixedly connected with a rotating column 21, the outer wall of the rotating column 21 is fixedly connected with a film-forming tooth 22, the rotating column 21 and the rotating rod 16 are both arranged inside the feeding bin 14;

[0031] Specifically, the output end of the motor 15 is used to drive the rotating rod 16 to start rotating, which not only drives the rotation of the blade 17, but also makes the cam wheel 18 rotate synchronously. The sharp edge of the blade 17 rotates at high speed to quickly and accurately cut the residual film on the ground, effectively preventing the problem that the residual film area is too large to be naturally absorbed by the soil. At the same time, the rotation of the cam wheel 18 is closely connected with the cam wheel 20 through the transmission belt 19, so that the cam wheel 20 also rotates. The rotation of the cam wheel 20 further drives the rotation of the rotating column 21. The film-removing teeth 22 on the outer wall of the rotating column 21 scrape the cut residual film from the ground during the rotation process, which not only realizes the rapid recovery of the residual film, but also ensures the efficiency and quality of the recovery process.

[0032] Working principle: when it is necessary to use the air-suction residual film recovery device, first drive the L-shaped block 6 to pull to both sides, so that the torsion spring 8 is reversed, and then the collecting plate 3 is inserted into the preset through hole on the top of the wind bin 1, so that the collecting plate 3 moves to the inner wall of the positioning plate 2, and when the collecting plate 3 is completely moved to the inside of the wind bin 1, the L-shaped block 6 is released, and at this time, the torsion spring 8 is no longer subjected to force to rotate, thereby driving the L-shaped block 6 to be stuck on the top of the mounting plate 4 to fix the collecting plate 3, and then the screw rod 9 is driven to rotate inside the special-shaped connecting block 5, thereby driving the limit block 10 to press against one side of the L-shaped block 6 to prevent it from moving at will, thereby realizing the installation of the collecting plate 3, and then the limit block 10 is pulled back by rotating the screw rod 9 in the opposite direction, and then the L-shaped block 6 is pulled again, and the residual film on the collecting plate 3 and the outer wall of the collecting plate 3 can be taken out through the mounting plate 4, thereby achieving the effect of collecting and recovering the residual film;

[0033] In addition, the fan 11 is driven to absorb external air through the feeding bin 14, and in this process, the residual film is also absorbed inward, so that the residual film is hung on the outer wall of the collecting plate 3, and finally discharged through the exhaust hole 13. In this process, the air can be further filtered through the filter 12 to prevent the debris in the air from causing damage to the fan 11;

[0034] Finally, the output end of the motor 15 drives the rotating rod 16 to rotate, thereby driving the blade 17 and the cam wheel 18 to rotate through the rotating rod 16, and the residual film is cut by the rotation of the blade 17 to prevent the residual film area from being too large to be absorbed. At the same time, the rotation of the cam wheel 18 drives the cam wheel 20 to rotate through the transmission belt 19, thereby driving the rotating column 21 to rotate, and then the film is removed through the film removing teeth 22 on the outer wall of the rotating column 21, thereby achieving more efficient residual film recovery.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
