Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, specifically referring to a residual film picking and recycling device based on electrostatic adsorption. Background Technology

[0002] Mechanized recycling of residual film has become a future trend, and the recycling of residual film mainly involves granulation, which requires low impurity content. However, existing recycled residual film contains a large amount of impurities, mainly soil and straw. Therefore, the removal of impurities has become the key to restricting the reuse of residual film.

[0003] In addition, existing residual film recycling equipment has the following problems: because straw and stubble are picked up together during recycling, and mechanical separation mechanisms are sensitive to stubble entanglement, separation failure is easily caused, leading to drum blockage and machine shutdown. For devices that use gravity screening, the film-soil separation rate is low, and the soil content of the recycled residual film is high. Utility Model Content

[0004] The technical problems to be solved by this invention are the problems of machine downtime caused by the entanglement of residual film and stubble in the prior art, and the defects of incomplete separation caused by using gravity to clean impurities.

The surface of the drum is provided with spiral auger blades, and the drum is divided into a coaxial left drum and a right drum. The right drum is provided with an electrostatic adsorption layer, which can be made by combining copper electrodes with an insulating substrate. The outside of the right drum is also provided with a separation rod arranged perpendicular to the axial direction for peeling off the root stubble.

The output shaft of the motor is connected to the rotating shaft on one side of the left roller, and the generating end of the electrostatic generator is rotatably connected to the electrostatic adsorption layer on the right roller through a bearing.

[0013] Preferably, the shovel head includes a mounting part fixed to the shovel frame and a separating part fixed to the separating component.

[0039] Example 1

[0040] Please see Figure 1 and Figure 2 As shown, the present invention proposes a residual film picking and recycling device based on electrostatic adsorption, including a support mechanism 1. The support mechanism 1 includes a frame 11, which is assembled with a mobile vehicle such as an agricultural tractor to provide the power for movement. The bottom of the frame 11 is provided with a discharge rack 12, which includes a downwardly arched separation area 101 and an inlet area 102 connected to one side of the bottom of the separation area 101 and arranged horizontally. The side of the separation area 101 away from the inlet area 102 is provided with a back plate area 103, which is arranged perpendicular to one end of the separation area 101.

[0041] As further explanation: A tilting shaft 14 is also provided on the top of the frame 11 and is rotatably connected to the moving vehicle body. It is equipped with a motor 35 or a telescopic rod for driving and adjusting the angle between the discharge rack 12 and the soil.

[0042] This application also includes a shovel lifting device 2 located at the front end of the discharge rack 12, which includes a shovel frame 21 fixed to the bottom of the front end of the inlet area 102 and shovel heads 22 evenly distributed on one side of the shovel frame 21, with a separator 23 connecting the shovel heads 22.

[0043] refer to Figures 5-7 As shown, the shovel head 22 includes a mounting part 201 fixed to the shovel frame 21 and a separating part 202 fixed to the separating member 23. The mounting part 201 is U-shaped and fixed to the back of the shovel frame 21. The separating part 202 extends downward about the bottom sides of the mounting part 201 and forms a groove structure with a J-shaped cross section. The separating member 23 is located between the mounting part 201 and the separating part 202, and the outer side of the separating member 23 is provided with an inclined separating strip 203. Adjacent separating strips 203 form a triangular separating surface 204. The bottom of the separating part 202 is pointed.

[0044] When using this structure, the workflow for residual film pickup is as follows:

[0045] After being attached to the tractor frame 11, the machine begins to move. The shovel head 22 is preferably flush with the soil or penetrates 3-5 cm into the soil. Triangular baffles 13 are provided on both outermost sides of the shovel head 22. It is important to note that the shovel head 22 is ideally tilted towards the soil, with the front end in contact with the soil and the rear end suspended in the air. During movement, the residual film is scooped up, and simultaneously, the separating cut surface 204 of the shovel head 22 forms a triangular shearing surface. This part wedges into the soil, cutting grass roots, weeds, etc., and then the residual film and impurities enter the separation zone 101. A filter screen is provided at the bottom of the separation zone 101. During this process, due to the bottom filter screen, smaller diameter soil impurities pass through the filter screen and return to the soil under the influence of gravity. Because the cutting is performed before feeding, the possibility of entanglement is reduced.

[0046] Example 2

[0047] See Figures 1-4 As shown, in order to improve the effect of residual film separation, this embodiment also includes an adsorption separation device 3 located in the middle section of the discharge rack 12, which includes a roller 31. The roller 31 has rotating shafts on both sides that are rotatably connected to the side wall of the separation zone 101. The surface of the roller 31 is provided with spiral auger blades 32, and the roller 31 is divided into a coaxial left roller 301 and a right roller 302. The right roller 302 is provided with an electrostatic adsorption layer 33, wherein the electrostatic adsorption layer 33 can be made by combining copper electrodes with an insulating substrate. The outside of the right roller 302 is also provided with separation rods 34 arranged perpendicular to the axial direction. The separation rods 34 are distributed in a cross shape on the outer periphery of the roller 31 and are evenly distributed in multiple sets along the axial direction for peeling off the root stubble.

[0048] The roller 31 has a motor 35 and an electrostatic generator 36 respectively installed on both sides of the outer side of the separation zone 101. The output shaft of the motor 35 is connected to the rotating shaft on one side of the left roller 301, and the generating end of the electrostatic generator 36 is rotatably connected to the electrostatic adsorption layer 33 on the right roller 302 via a bearing. The spiral auger blades 32 are continuously arranged across the left roller 301 and the right roller 302, and their surfaces are covered with a 0.5mm thick alumina ceramic insulating layer.

[0049] Preferably, the right roller 302 occupies 60%-80% of the axial length of the roller 31, and the left 10% area of ​​the right roller 302 is not provided with an electrostatic adsorption layer 33 to form a buffer zone. The electrostatic adsorption layer 33 is provided on the inner surface of the right roller 302 for adsorption of residual film.

[0050] As a further example:

[0051] The rear end of the support mechanism 1 is also provided with a conveying mechanism 4 that communicates with the back plate area 103. The conveying mechanism 4 includes a conveying cavity 41 that is arranged in an inclined shape. A conveying hole is provided at the lower end of the conveying cavity 41. The conveying hole is connected to the end of the right roller 302 that is away from the left roller 301. A fan 5 is provided on one side above the conveying hole. The exhaust end of the fan 5 is provided corresponding to the right roller 302 below.

[0052] This structure illustrates the workflow of residual membrane separation:

[0053] The tractor continues to move forward at a constant speed. The switch of motor 35 is turned on, and the left drum 301 rotates in the forward direction to push the material. The shoveled material is conveyed to the right drum 302 through the spiral auger blades 32. The external separating rod 34 is used to break up roots, soil and other impurities, and some impurities fall from the filter screen.

[0054] Then, the electrostatic generator 36 is switched on, and the electrostatic adsorption layer 33 is energized to adsorb the residual film. After a period of time, the blower 5 is switched on, and the exhaust end of the blower 5 is perpendicular to the end face of the right roller 302. Together with the right roller 302 rotating towards the conveying hole, the airflow blows the residual film into the conveying cavity 41. The air discharged by the blower 5 can further dry the residual film that is contaminated with moisture from the damp soil, further improving the efficiency of separating the residual film from impurities. A conveyor belt can be set in the conveying cavity 41 to transport it upwards, and a compression structure can be set to compress the residual film, making it easier to collect, improving the degree of film-soil separation, and enhancing the effect of residual film transfer and detachment.

[0055] In addition, a discharge hole is provided on the side of the separation zone 101 near the left roller 301. Manual cleaning can be performed periodically after the machine is stopped.

[0056] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
