Description

Technical Field

[0001] This application relates to the field of waste film recycling technology, and in particular to a residual film pickup machine. Background Technology

[0002] After the use of plastic film, it is necessary to collect the plastic film from the soil surface in a unified manner to ensure soil quality. If the residual film is not completely removed when the plastic film is collected from land that has been covered with plastic film for a long time, it will be difficult to degrade and will cause soil pollution. On the one hand, it will harm the health and safety of crops, and on the other hand, it will cause a decline in soil fertility and crop yield reduction.

[0003] The residual film recycling machines in related technologies can only clean and recycle residual film in shallow soil, but cannot clean and recycle residual film in deep soil. The residual film recycling rate of the machines does not meet the expected results. Year after year, the residual film in the soil accumulates more and more, causing soil pollution and seriously affecting the planting of crops. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a residual film collection machine, which can effectively solve the problem of the inability to clean and recycle residual plastic film in deep soil, making the cleaning and recycling of residual plastic film more thorough.

[0005] This application provides a residual film pickup machine, including: a frame, a primary residual film pickup machine and a secondary residual film pickup machine, wherein the primary residual film pickup machine is disposed on the frame, the secondary residual film pickup machine is disposed at the bottom of the frame, and the secondary residual film pickup machine is disposed close to the primary residual film pickup machine;

[0006] The primary residual film pickup machine includes a film pickup belt assembly, multiple film pickup rods, and at least three functional rollers. Each of the functional rollers is mounted on the frame. The film pickup belt assembly is wrapped around each of the functional rollers. The multiple film pickup rods are arranged sequentially and evenly on the film pickup belt assembly, and the film pickup belt assembly has a polygonal ring structure.

[0007] The secondary residual film pickup machine includes a pickup roller, a chain drive device, and two roller shaft fixing discs. The pickup roller includes a roller frame formed by multiple evenly arranged roller support rods. Each roller support rod has a spring tooth fixing groove. Multiple film picking spring teeth are arranged side by side in each spring tooth fixing groove. Each film picking spring tooth includes a vertical part and a bending part. One end of the vertical part is located in the spring tooth fixing groove, and the other end of the vertical part extends out of the corresponding spring tooth fixing groove and is set perpendicular to the roller support rod. The other end of the vertical part is connected to the bending part. The included angle between the vertical part and the bending part is greater than 135°.

[0008] The chain drive device includes a first roller shaft, a second roller shaft, a first drive chain, and a second drive chain. Both ends of the first and second roller shafts are respectively mounted on two roller shaft fixing discs. Both ends of the first and second roller shafts are respectively provided with drive sprockets. Multiple positioning elements are arranged side-by-side on both sides of the first and second drive chains. Each roller support rod has locking plates at both ends that match the positioning elements. The first drive chain meshes with the drive sprockets at one end of the first and second roller shafts, and the second drive chain meshes with the drive sprockets at the other end of the first and second roller shafts. The locking plate at one end of each roller support rod is locked to the positioning elements on both sides of the first drive chain, and the locking plate at the other end of each roller support rod is locked to the positioning elements on both sides of the second drive chain.

[0009] The residual film picking machine according to the embodiments of this application has at least the following beneficial effects: By combining the three functional rollers in the primary residual film picking machine with the film picking belt assembly and the film picking rod, the machine achieves the picking, removal, and removal of residual mulch film and agricultural weeds, thereby realizing the picking operation of shallow mulch film in a mechanized manner; the locking plates at both ends of each roller support rod and the corresponding positioning parts on the first and second transmission chains are mutually locked, realizing the connection between the roller support rod and the first and second transmission chains; by controlling the first and second roller shafts to move counterclockwise simultaneously, the first and second roller shafts drive the multiple roller support rods through the first and second transmission chains. The pickup roller rotates counterclockwise, which in turn drives multiple film-picking springs to rotate counterclockwise. When the roller support rod drives the corresponding multiple film-picking springs to rotate to the lowest point, the film-picking springs penetrate vertically into the ground and pick up the deep film during continuous rotation. The film-picking springs then continue to move counterclockwise during the rotation of the roller support rod to the position corresponding to the film-picking rod in the primary residual film pickup machine. The primary residual film pickup machine then transports the deep film picked up by the film-picking springs out. By setting the film-picking springs to have vertical and bending parts, after picking up the film and transporting it to the position corresponding to the film-picking rod, it is prevented that the film-picking springs will carry the film backward. By coordinating primary and secondary residual film collection machines, not only can the primary machine clean up residual film in shallow soil, but the secondary machine can also clean up residual film in deeper soil layers. This effectively removes residual film from deeper areas, reducing soil pollution and playing a vital role in maintaining sustainable agricultural development. The roller frame, formed by multiple evenly arranged roller support rods, has multiple film-picking spring teeth arranged side-by-side in each of its spring tooth fixing slots. This significantly increases the working area of ​​the picking spring teeth during film picking, preventing incomplete film removal due to insufficient picking spring teeth. When the picking spring teeth pick up residual film from deeper layers, it's equivalent to loosening the soil while separating the residual film, thus saving labor costs. This design effectively solves the problem of inability to clean and recycle residual film in deep soil layers, making the cleaning and recycling of residual film more thorough.

[0010] According to some embodiments of this application, each of the film-picking spring teeth is provided with a spring at one end connected to the corresponding spring tooth fixing groove.

[0011] According to some embodiments of this application, each of the roller fixing discs is provided with a corresponding connecting plate, and the two roller fixing discs are respectively located near the bottom of both sides of the frame, and the roller fixing discs are connected to the frame through the corresponding connecting plates.

[0012] According to some embodiments of this application, each of the locking plates includes a bolt fastener and a locking plate, the locking plate being disposed close to a corresponding positioning member, and the locking plate being connected to the positioning member via the corresponding bolt fastener.

[0013] According to some embodiments of this application, the three functional rollers are a film-collecting roller, a blemish-removing roller, and a film-removing roller. The frame includes a front end, a middle end, and a rear end, which are connected sequentially. The blemish-removing roller and the film-removing roller are fixedly mounted on the top of the middle end of the frame, and the film-collecting roller is fixedly connected to the bottom of the middle end of the frame. The film-collecting belt assembly is wrapped around the film-collecting roller, the blemish-removing roller, and the film-removing roller. The film-collecting roller is located below the blemish-removing roller and the film-removing roller, and the film-collecting roller, the blemish-removing roller, and the film-removing roller are arranged axially parallel.

The traction frame is connected to the front end of the frame. The film lifting mechanism includes a film lifting frame and a plurality of film lifting rods. The film lifting frame is arranged laterally at the front end of the frame. The plurality of film lifting rods are arranged perpendicular to the film lifting frame. Each film lifting rod is provided with a corresponding film lifting tooth. The film lifting tooth is connected to the end of the film lifting rod away from the film lifting frame.

[0036] After the use of plastic film, it is necessary to collect the plastic film from the soil surface in a unified manner to ensure soil quality. If the residual film is not completely removed when the plastic film is collected from land that has been covered with plastic film for a long time, it will be difficult to degrade and will cause soil pollution. On the one hand, it will harm the health and safety of crops, and on the other hand, it will cause a decline in soil fertility and crop yield reduction.

[0037] The residual film recycling machines in related technologies can only clean and recycle residual film in shallow soil, but cannot clean and recycle residual film in deep soil. The residual film recycling rate of the machines does not meet the expected results. Year after year, the residual film in the soil accumulates more and more, causing soil pollution and seriously affecting the planting of crops.

[0038] To address the aforementioned problems, this application proposes a residual film pickup machine. The embodiments of this application will be further described below with reference to the accompanying drawings.

[0039] Reference Figures 1 to 6This application provides a residual film pickup machine, including a frame 400, a primary residual film pickup machine 200, and a secondary residual film pickup machine 100. The primary residual film pickup machine 200 is mounted on the frame 400, and the secondary residual film pickup machine 100 is located at the bottom of the frame 400, close to the primary residual film pickup machine 200. The primary residual film pickup machine 200 includes a film pickup belt assembly, multiple film pickup rods 220, and at least three functional rollers. Each functional roller is mounted on the frame 400, and the film pickup belt assembly wraps around each functional roller. The multiple film pickup rods 220 are evenly arranged sequentially on the film pickup belt assembly, and the film pickup belt... The components have a polygonal ring structure; the secondary residual film pickup machine 100 includes a pickup roller, a chain drive device, and two roller shaft fixing discs 110. The pickup roller includes a roller frame formed by multiple evenly arranged roller support rods 120. Each roller support rod 120 has a spring tooth fixing groove 121. Multiple film picking spring teeth 122 are arranged side by side in each spring tooth fixing groove 121. Each film picking spring tooth 122 includes a vertical part 123 and a bending part 124. One end of the vertical part 123 is located in the spring tooth fixing groove 121, and the other end of the vertical part 123 extends out of the corresponding spring tooth fixing groove 121 and is perpendicular to the ground. The roller support rod 120 is provided, and the other end of the vertical part 123 is connected to the bending part 124. The included angle between the vertical part 123 and the bending part 124 is greater than 135°. The chain drive device includes a first roller shaft 111, a second roller shaft 112, a first drive chain 113, and a second drive chain 114. Both ends of the first roller shaft 111 and the second roller shaft 112 are respectively passed through two roller shaft fixing discs 110. Both ends of the first roller shaft 111 and the second roller shaft 112 are respectively provided with drive sprockets. Both sides of the first drive chain 113 and the second drive chain 114 are respectively provided with multiple positioning elements 1 arranged side by side. 16. Each roller support rod 120 has a locking plate 117 at both ends that matches the positioning member 116. The first transmission chain 113 meshes with the transmission sprockets at one end of the first roller shaft 111 and the second roller shaft 112 respectively. The second transmission chain 114 meshes with the transmission sprockets at the other end of the first roller shaft 111 and the second roller shaft 112 respectively. The locking plate 117 at one end of each roller support rod 120 is locked to the positioning members 116 on both sides of the first transmission chain 113. The locking plate 117 at the other end of each roller support rod 120 is locked to the positioning members 116 on both sides of the second transmission chain 114.

[0040] It should be noted that the film picking rod 220 and the film picking belt assembly form a toothed structure. Each functional roller is equipped with a corresponding drive motor, which is connected to the corresponding functional roller. The four functional rollers are arranged in parallel along the axis. The film picking belt assembly includes multiple film picking belts 210, which are sequentially wrapped around the three functional rollers and are arranged side by side with intervals.

[0041] It should be noted that the included angle between the vertical part 123 and the bent part 124 is greater than 135° and less than 180°.

[0042] It should be noted that during the forward movement of the residual film pickup machine, the pickup roller rotates clockwise. When the film-picking spring 122 is at its lowest point, it is perpendicular to the ground, and the residual film is in contact with it. The film-picking spring 122 has a certain degree of elasticity and will not break even when it collides with hard materials such as stones. As the pickup roller rotates, when the film-picking spring 122 moves to the front of the pickup roller, it is in a slightly downward horizontal position. At this time, impurities slide out of the residual film. As the pickup roller continues to rotate, when the film-picking spring 122 moves to the closest point to the film-picking rod 220, the film-picking rod 220 picks up the residual film, thus separating the residual film from the film-picking spring 122. As the first roller shaft 111 and the second roller shaft 112 continue to rotate, the pickup roller and the film-picking spring 122 on the pickup roller rotate under the action of the first transmission chain 113 and the second transmission chain 114, so that the film-picking spring 122 is perpendicular to the pickup roller when it approaches the ground, and continues to pick up the residual film.

[0043] In this application, the three functional rollers of the primary residual film pickup machine 200, combined with the film pickup belt assembly and the film pickup rod 220, are used to pick up, remove, and remove agricultural weeds from residual mulch film, thereby achieving the pickup operation of shallow mulch film in a mechanized manner. The locking plates 117 at both ends of each roller support rod 120 and the corresponding positioning parts 116 on the first transmission chain 113 and the second transmission chain 114 are mutually locked to achieve the connection between the roller support rod 120 and the first transmission chain 113 and the second transmission chain 114. By controlling the first roller shaft 111 and the second roller shaft 112 to move counterclockwise at the same time, the first roller shaft 111 and the second roller shaft 112 drive the pickup roller composed of multiple roller support rods 120 through the first transmission chain 113 and the second transmission chain 114. The counterclockwise movement causes multiple film-picking spring teeth 122 to move counterclockwise. When the roller support rod 120 drives the corresponding multiple film-picking spring teeth 122 to rotate to the lowest point, the film-picking spring teeth 122 are vertically inserted into the ground and pick up the deep film during the continuous rotation. The film-picking spring teeth 122 continue to move counterclockwise during the rotation of the roller support rod 120 to the position corresponding to the film-picking rod 220 in the primary residual film picking machine 200. Then, the primary residual film picking machine 200 transports the deep film picked up by the film-picking spring teeth 122 out. By setting the film-picking spring teeth 122 to a vertical part 123 and a bending part 124, when the film is picked up and transported to the position corresponding to the film-picking rod 220, it is prevented that the film-picking spring teeth 122 will carry the film backward. By cooperating with the primary residual film picker 200 and the secondary residual film picker 100, not only can the primary residual film picker 200 clean the mulch film in the shallow soil, but the secondary residual film picker 100 can also clean the mulch film residue in the deeper soil. This effectively removes the mulch film residue that was not cleaned in the deep layers, reducing soil pollution and playing a vital role in maintaining the sustainable development of agricultural production. The roller frame formed by multiple evenly arranged roller support rods 120 has multiple film-picking spring teeth 122 arranged side by side in the spring tooth fixing groove 121 of each roller frame. This greatly increases the working area of ​​the film-picking spring teeth 122 when picking up the film, avoiding the problem of incomplete cleaning of residual film due to insufficient film-picking spring teeth 122. When the film-picking spring teeth 122 pick up the residual film in the deep layers, it is equivalent to loosening the soil at the same time as separating the residual film, thus saving labor costs. This application, through this setup, can effectively solve the problem of the inability to clean and recycle plastic film residue in deep soil, making the cleaning and recycling of plastic film residue more thorough.

[0044] Reference Figure 2 and Figure 4 It is understandable that each of the membrane spring teeth 122 is provided with a spring 125 at the end connected to the corresponding spring tooth fixing groove 121.

[0045] It should be noted that by adding a spring 125 to the film-picking spring tooth 122, the force of the spring 125 can cause the film-picking spring tooth 122 to move upward a certain distance when it encounters a hard object during field operations, effectively reducing rigid collisions, realizing the self-protection of the film-picking spring tooth 122, and improving the service life of parts and the operational reliability of the whole machine.

[0046] It should be noted that the residual film collection machine in this application has a simple structure and is easy to operate. By setting up a primary residual film collection machine 200 and a secondary residual film collection machine 100, residual film of different sizes can be collected separately, avoiding the omission of residual film. Furthermore, by adding a spring 125 to the film picking spring tooth 122, the film picking spring tooth 122 can adapt to changing land conditions, resulting in good residual film collection effect.

[0047] Reference Figures 1 to 4 It is understood that each roller fixing plate 110 is provided with a corresponding connecting plate 115. The two roller fixing plates 110 are respectively located near the bottom of both sides of the frame 400, and the roller fixing plates 110 are connected to the frame 400 through the corresponding connecting plates 115.

[0048] It should be noted that by setting the connecting plate 115, the roller fixing plate 110 is connected to the frame 400, thereby connecting the secondary residual film pickup machine 100 to the frame 400.

[0049] Reference Figure 2 and Figure 4 It is understood that each locking plate 117 includes a bolt fastener and a locking plate 117. The locking plate 117 is set close to the corresponding positioning member 116, and the locking plate 117 and the positioning member 116 are connected by the corresponding bolt fastener.

[0050] It should be noted that the connection between the roller support rod 120 and the first transmission chain 113 and the second transmission chain 114 is achieved through the combination of bolt fasteners, locking plate 117 and positioning member 116. This allows the first transmission chain 113 and the second transmission chain 114 to rotate simultaneously when driven by the transmission sprocket, thereby driving the roller support rod 120 and the film picking spring teeth 122 in the spring tooth fixing groove 121 opened in the roller support rod 120 to rotate at the same time.

[0051] Reference Figure 1 , Figures 5 to 8It is understood that the three functional rollers are film picking roller 230, impurity removal roller 240, and film stripping roller 250. The frame 400 includes a front end, a middle end, and a rear end, which are connected sequentially. The impurity removal roller 240 and the film stripping roller 250 are fixedly installed at the top of the middle end of the frame, and the film picking roller 230 is fixedly connected to the bottom of the middle end of the frame. The film picking belt assembly is wrapped around the film picking roller 230, the impurity removal roller 240, and the film stripping roller 250. The film picking roller 230 is located below the impurity removal roller 240 and the film stripping roller 250, and the film picking roller 230, the impurity removal roller 240, and the film stripping roller 250 are arranged in parallel axial direction.

[0052] It should be noted that the impurity removal roller 240 has several annular impurity removal grooves parallel to each other on its roller surface, and the film removal roller 250 has several annular film removal grooves parallel to each other on its roller surface. The film picking belt assembly includes multiple film picking belts 210, which pass over the annular impurity removal grooves of the corresponding impurity removal roller 240 and the annular film removal grooves of the film removal roller 250. The diameter of the impurity removal roller 240 is smaller than the diameter of the film removal roller 250, the depth of the annular impurity removal groove is smaller than the length of the film picking rod 220, and the length of the film picking rod 220 is smaller than the depth of the annular film removal groove.

[0053] Specifically, when the film-collecting rod 220 hooks up the residual film, the residual film is generally caught at the end of the film-collecting rod 220. At the same time, residual crop branches and leaves, mixed soil clods and other agricultural debris are also hooked up by the film-collecting rod 220 and are generally hooked onto the rod body of the film-collecting rod 220. As the film-collecting belt assembly operates, the film-collecting rod 220 passes through the impurity removal roller 240 and through the annular impurity removal groove of the impurity removal roller 240. At this time, because the depth of the annular impurity removal groove is less than the length of the film-collecting rod 220, the residual film hanging at the end of the film-collecting rod 220 is not removed, but only the agricultural debris on the rod body of the film-collecting rod 220 is removed. As the film-collecting belt 210 continues to operate, the film-collecting rod 220 passes through the annular film removal groove of the film removal roller 250. At this time, because the length of the film-collecting rod 220 is less than the depth of the annular film removal groove, the residual film hooked on the film-collecting rod 220 falls off.

[0054] Reference Figures 7 to 8 It is understandable that the residual film picking machine also includes a traction frame 300 and a film lifting mechanism 700. The traction frame 300 is connected to the front end of the frame. The film lifting mechanism 700 includes a film lifting frame 710 and multiple film lifting rods 720. The film lifting frame 710 is arranged horizontally at the front end of the frame. The multiple film lifting rods 720 are arranged perpendicular to the film lifting frame 710. Each film lifting rod 720 is provided with a corresponding film lifting tooth 730. The film lifting tooth 730 is connected to the end of the film lifting rod 720 away from the film lifting frame 710.

[0055] It should be noted that the film lifting teeth 730 are used to lift the film, and then the film picking rod 220 cooperates with the film lifting teeth 730 to ensure that the residual film scooped up by the film lifting teeth 730 is continuously picked up by the film picking rod 220 and transported to the film picking belt assembly; the residual film picking machine is connected to the external traction device through the traction frame 300. The whole machine is driven by mechanical transmission, which is output by the output shaft of the traction device and the whole machine works through transmission.

[0056] Reference Figures 7 to 8 It is understandable that the residual film picking machine also includes a film roll recovery device 600 and a moving mechanism 500. The film roll recovery device 600 is located at the tail end of the frame, and the moving mechanism 500 is located at the bottom of the tail end of the frame. The film roll recovery device 600 is located near the stripping roller 250.

[0057] It should be noted that the waste film can be recycled by the cooperation of the film recycling device 600 and the primary residual film picking machine 200, thereby reducing the impact of residual film on crop planting.

[0058] In some embodiments, the rear output shaft of the traction device is sequentially connected to the impurity removal roller 240, the film removal roller 250, the film roll recovery device 600, and the film roll recovery device 600 via sprocket and chain drive, thereby enabling the primary residual film pickup machine 200, the film roll recovery device 600, and the secondary residual film pickup machine 100 to move via the rear output shaft of the traction device.
