Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a ridge film recycling machine adapted for wide and narrow row ridging, mulching, and dense planting in dry land. Background Technology

[0002] Wide-narrow row ridge planting with mulch is a common agricultural planting method in arid and semi-arid regions of Northwest my country. This technique effectively inhibits soil moisture evaporation, increases soil temperature, and suppresses weed growth through mulch, significantly increasing crop yield. However, after fulfilling its mission of conserving moisture and increasing soil temperature, if the mulch is not removed in time, the residual mulch will damage soil structure, hinder crop root growth, affect agricultural machinery operations, and cause serious "white pollution."

[0003] Currently, existing film recycling machines on the market mainly use a simple winding recycling method, which has the following technical defects in actual use: Incomplete removal of impurities: During the recycling process, soil clumps, residual straw fragments, gravel, and other impurities often adhere to the surface of the plastic film. Traditional recycling machines lack effective film surface cleaning devices, causing impurities to be rolled into the winding rack along with the plastic film. This not only increases the impurity content of the plastic film roll, affecting subsequent resource utilization, but also scratches or punctures the plastic film during winding, causing secondary damage.

[0004] The cleaning methods are limited and the results are poor: Although some improved recycling machines have added fixed brushes or simple tapping devices, the brush bristles cannot generate high-frequency vibrations, making it difficult to remove firmly attached impurities; the tapping action is mostly passive or intermittently driven and is not synchronized with the winding action, resulting in low cleaning efficiency.

[0005] Redundant structure and high energy consumption: Existing recycling machines with cleaning functions often require additional independent drive motors, cylinders or hydraulic systems to achieve brushing, slapping or blowing, resulting in complex overall structure, high manufacturing cost and additional power consumption, which is not suitable for energy-saving requirements in field operations.

[0006] Inconvenient film roll removal after winding: In traditional machines, there is no quick separation structure between the winding shaft and the film roll. After the operation is completed, tools are needed to disassemble the shaft or damage the film roll to remove it, which is cumbersome, time-consuming and labor-intensive.

[0007] Therefore, those skilled in the art have provided a ridge film recycling machine adapted for wide and narrow row ridging, mulching, and dense planting in dry land to solve the problems mentioned in the background art. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides a ridge film recycling machine adapted for wide and narrow row ridging, mulching, and dense planting in dry land, thus solving the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a ridge film recycling machine adapted for wide and narrow row ridging, mulching, and dense planting in dryland, comprising a recycling machine body, a winding frame for winding mulch film rotatably connected inside the recycling machine body via a central shaft, a film inlet on the recycling machine body, a connector at one end of the recycling machine body, and a connecting arm fixedly connected to one side of the recycling machine body, the connecting arm being provided with: Guide rollers are used to guide the mulch film into place; The movable slot has a movable block slidably connected inside it; The slapping assembly includes two rotating plates arranged symmetrically at the top and bottom, and slapping blades fixedly connected to the adjacent surfaces of the two rotating plates; The drive assembly includes a connecting disk fixedly connected to one side of the rotating plate and a drive gear fixedly connected to the connecting disk, wherein the drive gear extends out of the moving block and meshes with a tooth groove formed in the moving slot; The linkage mechanism includes a rotating disk fixedly connected to one end of the central shaft, a limiting post eccentrically arranged on the rotating disk, and a connecting rod fixedly connected to the moving block at one end. The other end of the connecting rod is fixedly connected to a limiting frame, which is sleeved on the limiting post. When the central shaft drives the winding frame to rotate and take in the film, the rotating disk drives the connecting rod to reciprocate through the limiting post and the limiting frame, thereby driving the moving block to slide back and forth in the moving groove. At the same time, the driving gear rotates under the action of the tooth groove, and drives the two rotating plates to open and close periodically through the connecting disk, so that the beating blades intermittently beat the surface of the film.

[0010] As a further technical solution of the present invention, the connecting arm is also provided with a cleaning component, the cleaning component comprising: Two symmetrically arranged connecting plates are slidably connected between the two moving blocks, and the two connecting plates are connected by a spring; Multiple cleaning bristles are fixedly connected to the adjacent surfaces of the two connecting plates for contact with the upper and lower surfaces of the mulch film; Multiple first extrusion blocks are fixedly connected to the edge of the connecting disc, and multiple second extrusion blocks are fixedly connected to the end of the connecting plate; When the connecting disc rotates, the first pressing block intermittently presses the second pressing block, driving the two connecting plates to move relative to each other, causing the cleaning brush bristles to vibrate.

[0011] As a further technical solution of the present invention, both the first extrusion block and the second extrusion block are designed to be spherical.

[0012] As a further technical solution of the present invention, the connecting arm is also provided with a purging assembly, the purging assembly comprising: A piston cylinder is fixedly connected to the connecting arm, and its piston rod extends into the moving groove and contacts the moving block. A hollow tube is mounted on the rotating plate above, and multiple high-pressure nozzles are embedded in the hollow tube; A connecting pipe connects the air outlet of the piston cylinder to the hollow tube; The reciprocating motion of the moving block drives the piston rod to reciprocate, causing the piston cylinder to generate high-pressure gas, which is then sprayed onto the surface of the ground film through the high-pressure nozzle.

[0013] As a further technical solution of the present invention, a cover plate is connected to one side of the main body of the recycling machine via a hinge, and a connecting block is fixedly connected to one end of the central shaft. The connecting block is connected to a movable rod via a spring. When the cover plate is closed, it presses the movable rod to make it abut against and limit the winding frame. When the cover plate is opened, it releases the movable rod to separate it from the winding frame.

[0014] As a further technical solution of the present invention, one end of the main body of the recycling machine is connected to a limiting roller through a driving component. The limiting roller can move horizontally under the action of the driving component to limit the mulch film during the film collection process.

[0015] As a further technical solution of the present invention, the winding frame is provided with clamping springs for clamping the ends of the mulch film.

[0016] As a further technical solution of the present invention, the guide roller is connected to the connecting arm via a universal joint, and limit frames are provided on both sides of the guide roller.

[0017] This invention provides a ridge film recycling machine adapted for wide and narrow row ridging, mulching, and dense planting in dry land, which has the following advantages compared with the prior art: First, crush; then, blow; finally, tap – a three-stage cleaning process for high membrane surface cleanliness: A three-stage sequential cleaning process is designed, consisting of "vibrating brush bristle crushing + high-pressure airflow blowing + intermittent tapping and shaking." The cleaning brush bristles physically crush and peel off firmly attached impurities such as soil clumps and straw pieces under high-frequency, small-range vibration. The piston cylinder compresses air using the reciprocating motion of the moving block, and the resulting high-pressure airflow blows the crushed impurities away from the membrane surface. The flapping blades periodically close to intermittently tap the membrane surface, further shaking off residual fine particles.

[0018] The synergistic effect of these three factors significantly reduces the impurity content of the plastic film rolls, prevents the plastic film from being scratched by impurities during the winding process, and ensures the integrity and reuse value of the recycled plastic film.

[0019] Multi-functional and energy-efficient: By setting up a linkage mechanism consisting of a central shaft, rotating disk, eccentric limit post, limit frame, and connecting rod, the power of the winding frame rotating to take in the film is synchronously transmitted to the moving block, drive gear, and connecting disk. Without adding any independent power source, it simultaneously drives the beating component, cleaning component, and blowing component to operate sequentially. It achieves "winding is driving", has a compact structure, low energy consumption, and is suitable for field operation environments without external power.

[0020] Purely mechanical linkage ensures high reliability and low maintenance costs: all cleaning actions, such as tapping, brushing vibration, and air blowing compression, are powered and converted through purely mechanical structures such as gears, eccentric wheels, connecting rods, and cams, requiring no electronic sensors, controllers, or external air / hydraulic sources. It exhibits enhanced adaptability to harsh field environments, a low failure rate, and simple maintenance.

[0021] The quick-release mechanism ensures convenient operation: By incorporating a spring-loaded movable rod at the end of the central shaft, combined with the opening and closing control of the cover plate, the mechanism automatically limits the movement of the film roll during winding and automatically separates the rod from the film roll after the cover is opened. Operators can quickly retrieve the wound film roll without tools, greatly improving operational efficiency. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-8 This invention provides a technical solution for a ridge film recycling machine adapted for wide and narrow row ridging and dense planting in dryland: it includes a recycling machine body 1. The recycling machine body 1 has a frame structure, and a winding frame 5 is rotatably connected to its center via a central shaft 36. The winding frame 5 is used to wind the recycled mulch film. The front end of the recycling machine body 1 (with reference to the direction of mulch film travel) has a film inlet 6 for allowing the mulch film to enter the body. The rear end of the recycling machine body 1 is provided with a connector 10 for connecting to the suspension system of an external mobile device (such as a tractor).

[0026] A connecting arm 2 is fixedly connected to the right side of the main body 1 of the recycling machine. The connecting arm 2 is a horizontally extending beam structure. The front end of the connecting arm 2 is connected to a guide roller 4 via a universal joint 3. The guide roller 4 can adaptively deflect within a small range in multiple directions with the universal joint 3 to adapt to the slight undulations of the field ground. Limit frames 7 are provided on both the left and right sides of the guide roller 4 to prevent the plastic film from slipping laterally when entering.

[0027] like Figure 2 , Figure 3 and Figure 7As shown, the left end of the central shaft 36 penetrates the side wall of the main body 1 of the recycling machine and is fixedly connected to a rotating disk 19. The rotating disk 19 is disc-shaped, and a limit post 20 is fixedly installed at its non-center position (eccentric position). A limit frame 21 is movably fitted on the limit post 20. The limit frame 21 is a rectangular frame with its long side horizontally positioned. A connecting rod 22 is fixedly connected to the right side of the limit frame 21. The connecting rod 22 extends horizontally to the right, and its right end is fixedly connected to the moving block 12.

[0028] The upper and lower surfaces of the connecting arm 2 are respectively provided with moving grooves 11 extending along their length, and a moving block 12 is slidably installed in the moving groove 11. The right end of the connecting rod 22 is fixedly connected to the moving block 12. When the central shaft 36 drives the winding frame 5 to rotate, the rotating disk 19 rotates synchronously, and the eccentrically set limiting post 20 makes a circular motion within the limiting frame 21, pushing the limiting frame 21 and the connecting rod 22 to make periodic reciprocating linear motion in the horizontal direction, thereby driving the moving block 12 to slide back and forth in the moving groove 11.

[0029] Please see Figure 3 , Figure 5 and Figure 8 The movable block 12 has a hollow interior with two symmetrically extending shaft ends on its upper and lower sides. A drive gear 18 is rotatably mounted on the shaft ends of the movable block 12 via a connecting disc 17. A portion of the teeth of the drive gear 18 extend outside the movable block 12 and mesh with the tooth grooves 13 formed on the inner wall of the movable groove 11. The connecting disc 17 is coaxially and fixedly connected to the drive gear 18 and can rotate together with the drive gear 18.

[0030] Two rotating plates 14 are fixedly connected to the upper and lower connecting plates 17 respectively, forming a symmetrical arrangement. Multiple beating blades 16 are fixedly connected to the adjacent surfaces (i.e., opposite surfaces) of the two rotating plates 14. The beating blades 16 can be made of flexible and wear-resistant materials (such as rubber or polyurethane) to reduce damage to the mulch film.

[0031] When the moving block 12 slides back and forth in the moving groove 11, the drive gear 18 rotates alternately in both directions due to meshing with the tooth groove 13, and drives the two rotating plates 14 to perform periodic opening and closing movements through the connecting plate 17. When the two rotating plates 14 are closed to the minimum distance, the upper and lower beating blades 16 apply intermittent beating to the surface of the mulch film passing between them.

[0032] like Figure 5 , Figure 8As shown, two connecting plates 28 are symmetrically arranged between the two movable blocks 12. The horizontal ends of the two connecting plates 28 are connected to the inner walls of the movable blocks 12 by springs (not marked in the figure), allowing the two connecting plates 28 to slide relative to each other in a small range in the horizontal direction. Multiple cleaning bristles 29 are fixedly arranged on the adjacent surfaces of the two connecting plates 28, with the ends of the cleaning bristles 29 contacting each other to ensure that they fit tightly against the upper and lower surfaces of the mulch film.

[0033] Multiple first pressing blocks 30 are uniformly fixed circumferentially along the edge of the connecting plate 17. Correspondingly, multiple second pressing blocks 31 are fixed to the end of the connecting plate 28 facing the connecting plate 17. Both the first pressing blocks 30 and the second pressing blocks 31 are spherical in design to reduce wear and jamming risks during contact.

[0034] When the connecting disc 17 rotates, the first pressing block 30 intermittently presses the second pressing block 31, driving the two connecting plates 28 to move relative to each other against the spring force. After the first pressing block 30 passes the second pressing block 31, the spring resets and drives the connecting plates 28 back to their original positions. This process repeats, causing the cleaning brush bristles 29 to vibrate at high frequency and small amplitude, crushing and peeling off firmly attached impurities on the surface of the mulch film.

[0035] Please see Figure 4 and Figure 6 A piston cylinder 23 is fixedly mounted on the upper surface of the connecting arm 2. The piston rod 24 of the piston cylinder 23 extends into the moving groove 11 and remains in contact with the side of the moving block 12. When the moving block 12 slides back and forth, it repeatedly pushes the piston rod 24, causing compressed air to be generated inside the piston cylinder 23.

[0036] The air outlet of the piston cylinder 23 is connected to the hollow tube 26 via the connecting pipe 25. The hollow tube 26 is embedded and fixed inside the upper rotating plate 14, and multiple high-pressure nozzles 27 are embedded on the lower surface of the hollow tube 26 (towards the mulch film). Compressed air is ejected at high speed through the high-pressure nozzles 27, forming a fan-shaped airflow to blow away and remove impurities after the cleaning brush bristles 29 have been crushed.

[0037] like Figure 2 and Figure 7 As shown, a cover plate 9 is connected to the left side of the main body 1 of the recycling machine via a hinge 8. A connecting block 34 is fixedly connected to the central shaft 36 on the left side of the main body 1 of the recycling machine. The connecting block 34 is rotatably connected to a movable rod 35 via a spring (not shown). When the cover plate 9 is closed, its inner wall presses against the movable rod 35, causing the free end of the movable rod 35 to abut against the end of the winding frame 5 or the side of the wound mulch film roll, forming a limit to prevent the film roll from loosening or axially shifting during winding. After the cover plate 9 is opened, the movable rod 35 automatically rotates outward under the action of the spring, separating from the winding frame 5 and releasing the limit. At this time, the operator can directly pull the wound mulch film roll out of the central shaft 36.

[0038] Please see Figure 1 and Figure 7 The front end of the main body 1 of the recycling machine (on the same side as the connecting arm 2) is also equipped with a drive component 32, which can be a manual screw, an electric push rod, or a cylinder. The movable end of the drive component 32 is connected to a limit roller 33, which can move horizontally under the drive of the drive component 32 to adjust its limiting position according to the actual width of the mulch film, ensuring that the mulch film remains centered before entering the film inlet 6 and avoiding skewed winding.

[0039] A clamping spring 15 is fixedly installed on the outer circumferential surface of the winding frame 5. When inserting the film for the first time, the end of the film can be inserted under the clamping spring 15, and the elasticity of the spring will be used to clamp the end of the film onto the winding frame 5 to prevent slippage in the early stage of winding.

[0040] The working principle of this invention is as follows: When it is necessary to recycle the mulch film, first pull one end of the mulch film out from the ground, pass through the two limiting frames 7, the upper surface of the guide roller 4, and the cleaning brush 29 between the two connecting plates 28 in sequence, and finally extend into the body 1 of the recycling machine through the film inlet 6 and be wound on the winding frame 5. The end of the mulch film is fixed by the clamping spring piece 15.

[0041] The central shaft 36 that drives the winding frame 5 to rotate can be connected to the wheels of an external mobile device (such as a tractor) via a pulley. When the mobile device moves, the central shaft 36 drives the winding frame 5 to rotate to take in the film. At the same time, the rotating disk 19 at the end of the central shaft 36 rotates synchronously. The eccentrically set limiting post 20 drives the limiting frame 21 and the connecting rod 22 to move horizontally back and forth, thereby causing the moving block 12 to slide back and forth in the moving groove 11.

[0042] Step 1: Crush impurities When the moving block 12 slides, the drive gear 18 rotates under the action of the tooth groove 13, which drives the two rotating plates 14 to rotate relative to each other through the connecting disc 17. The first pressing block 30 on the edge of the connecting disc 17 intermittently presses the second pressing block 31 at the end of the connecting plate 28, which, together with the spring, causes the two connecting plates 28 to generate high-frequency, small-amplitude relative motion, thereby driving the cleaning brush bristles 29 to vibrate and rub against the upper and lower surfaces of the ridge film, crushing and peeling off firmly attached impurities such as soil clumps, straw pieces, and stones adsorbed on the film surface, while simultaneously flattening and tidying the ridge film.

[0043] Step 2: High-pressure blowing During the reciprocating motion of the moving block 12, it continuously pushes the piston rod 24 to compress the piston cylinder 23, generating high-pressure gas. The high-pressure gas is transported to the hollow tube 26 through the connecting pipe 25, and finally ejected at high speed from multiple high-pressure nozzles 27, completely blowing away the crushed impurities from the surface of the ridge film and preventing secondary adhesion.

[0044] Step 3: Intermittent tapping Driven by the connecting disc 17, the two rotating plates 14 periodically close to their maximum extent, causing the beating blades 16 fixed on their adjacent surfaces to intermittently beat the upper and lower surfaces of the mulch film. The beating action can further shake off residual fine impurities and ensure that the mulch film remains flat and clean before being rolled up.

[0045] After winding is completed, open the cover plate 9. At this time, the cover plate 9 no longer squeezes the movable rod 35. The movable rod 35 rotates under the action of the spring and separates from the winding frame 5, releasing the restriction on the mulch film roll, and the wound mulch film can be taken out directly.

[0046] Meanwhile, the position of the limiting roller 33 can be adjusted under the action of the driving component 32, so that it can limit the film and ensure that it can be better recycled and wound up.

[0047] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
