Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a combined equipment for recycling and packaging residual film. Background Technology

[0002] With the popularization of large-scale and mechanized farming, plastic film mulching technology has been widely used in the cultivation of various crops such as cotton, corn, and vegetables. However, if the plastic film is not recycled in a timely and thorough manner after use, the residual film left in the soil will damage the soil structure, hinder crop root development, and cause environmental pollution.

[0003] Currently, the core function of existing residual film recycling equipment is to collect residual film from the field through a picking mechanism and then form it into neat bales through subsequent processes such as conveying, compression, and packaging. However, existing equipment still has significant technical shortcomings in practical applications, with low purity of recycled residual film and poor packaging quality being particularly prominent issues.

[0004] Specifically, the main problems with the contamination of residual film in existing recycling equipment are: firstly, the residual film easily adheres to the soil, making it difficult to separate effectively during subsequent recycling, resulting in a large amount of soil entering the baling process along with the residual film; secondly, the equipment lacks a targeted pre-sorting structure, allowing large impurities such as straw, weeds, and gravel left in the field to easily enter the recycling channel directly. After mixing with the residual film, these impurities not only affect the density of the bale but may also cause equipment jamming, wear, and other malfunctions.

[0005] In summary, existing combined equipment for recycling and baling residual film is insufficient to meet the demands of modern agriculture for efficient and high-quality recycling of residual film. There is an urgent need to address the problem of impurity contamination through technological optimization to improve the purity of recycled residual film and the quality of baling. Summary of the Invention

The scraper assembly includes a bushing and a plate. The bushing is coaxially arranged with the axle of the traveling wheel, and the plate is installed on the side wall of the bushing. The scraper assembly is configured to use the axle of the traveling wheel to drive the plate to make a circular motion, forming a channel for peeling off residual film at the intersection of the plate and the picking unit, and using the plate to guide the residual film to the transport unit. The inlet end of the conveying unit is located below the scraper assembly and is used to receive residual film. The conveying unit is configured to convey the residual film to the packaging unit. The packaging unit is located at the outlet end of the conveying unit and is used to collect and package the residual film.

[0008] Preferably, the pickup unit includes a fixed base and pickup teeth. The fixed base is fixedly connected to the rotating shaft, and the pickup teeth are arranged to extend outward along the radial direction of the fixed base.

[0009] Preferably, multiple pickup units are evenly spaced in the circumferential direction of the rotating shaft, and the pickup teeth of adjacent pickup units are staggered in the axial direction of the rotating shaft.

[0010] Preferably, the conveying unit includes a conveying frame, a driving roller, a driven roller, and a conveyor belt; the conveying frame is fixedly installed on the machine frame, the driving roller and the driven roller are rotatably installed at both ends of the conveying frame, the driving roller is connected to the driven roller through the conveyor belt, and the conveyor belt is provided with a waste removal hole.

[0014] Preferably, a soil loosening structure is provided in front of the picking component. The soil loosening structure includes soil loosening wheels, and multiple soil loosening wheels are arranged in a linear array along the axis of the rotating shaft.

[0015] Compared with existing technologies, the residual film recycling and baling equipment provided by this utility model has the following substantial features and advancements: This residual film recycling and baling equipment, through the coordinated operation of a scraper assembly and a picking unit, can efficiently remove residual film adhering to soil and pre-intercept large impurities such as straw, significantly improving the purity of the recycled residual film; the pure residual film combined with a continuous conveying design ensures that the baled packages are compact, neat, and highly dense, reducing downtime due to malfunctions; by intercepting impurities, it reduces equipment jamming and wear; relying on the walking wheel drive simplifies the structure, reduces energy consumption and maintenance costs, and improves operational stability; the integrated process shortens the operation cycle; it is compatible with various traction agricultural machinery and crop fields, meeting the needs of large-scale planting; it lowers the barrier to entry for farmers and reduces residual film pollution.

[0022] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, a residual film recycling and packaging combined equipment includes a frame 1 for connecting a traction device, a traveling wheel 6 on the frame 1, and a picking component 2, a scraper component 3, a conveying unit 4 and a packaging unit 5 arranged sequentially along the traveling direction of the traction device on the frame 1.

[0024] like Figure 2 As shown, the pickup assembly 2 includes a rotating shaft 21 and pickup units 22, with multiple pickup units 22 arranged in a ring around the axis of the rotating shaft 21. Figure 4 As shown, the picking component 2 is configured to use the walking wheel 6 to drive the rotating shaft 21 to rotate through the transmission structure 23, thereby driving multiple picking units 22 to pick up residual film in the field.

[0025] like Figure 3 and Figure 4 As shown, the scraper assembly 3 includes a bushing 31 and a plate body 32. The bushing 31 is coaxially arranged with the axle of the traveling wheel 6, and the plate body 32 is mounted on the side wall of the bushing 31. Figure 5 As shown, the scraper assembly 3 is configured to drive the plate body 32 to make a circular motion using the axle of the walking wheel 6, forming a channel for peeling off the residual film at the intersection of the plate body 32 and the picking unit 22, and using the plate body 32 to guide the residual film to the transport unit.

[0026] like Figure 3 As shown, the inlet end of the conveying unit 4 is located below the scraper assembly 3 and is used to receive residual film. The conveying unit 4 is configured to convey the residual film to the packaging unit 5.

[0027] like Figure 3 As shown, the packaging unit 5 is located at the outlet end of the conveying unit 4 and is used to collect and package the residual film.

[0028] Specifically, the frame 1 constitutes the main framework of the entire residual film recycling and baling combined equipment. It is usually made of high-strength steel and is formed into a rectangular or irregularly shaped multi-segment frame structure by welding or bolting. The front end of the frame 1 is equipped with a traction connection point, through which it is rigidly connected to agricultural traction equipment (such as a tractor), thereby enabling the entire equipment to move in the field.

[0029] The overall dimensions and strength of the frame 1 are designed to withstand the weight of the components and the impacts and vibrations generated during operation. The frame 1 is connected to the wheels 6 via bearing seats at the bottom.

[0030] The traveling wheels 6 provide support for the movement of the equipment. They are typically made of rubber tires, either inflatable or solid, and have high wear resistance and puncture resistance. The hub surface of the traveling wheels 6 is finely engraved with multiple anti-slip patterns, which significantly improve the traction performance and driving stability of the equipment in complex field conditions and prevent slippage by increasing the coefficient of friction with the ground, especially muddy or loose soil.

[0031] To facilitate the synchronous rotation of the picking components, the axle of the walking wheel 6 passes through the bearing housing and is rigidly connected to the drive sprocket of the transmission mechanism 8.

[0032] like Figure 2 As shown, a soil loosening structure 7 is arranged at the front end of the frame 1 along the direction of travel of the traction equipment. The soil loosening structure 7 includes multiple soil loosening wheels 71, which are arranged in a linear array and uniformly distributed along an axis parallel to the direction of travel of the frame 1, maintaining a certain axial distance from each other.

[0033] For example, each tiller 71 has multiple tiller teeth on the outer edge of its rim. These tiller teeth are typically forged from high-strength wear-resistant alloy steel. The tiller teeth are not simply arranged radially, but rather are evenly distributed in a spiral pattern along the rim surface of the tiller 71, forming a spiral soil-breaking structure.

[0034] As the equipment moves through the field, the loosening wheel 71 rolls on the ground, and its spiral loosening teeth use a combination of rotation and cutting to deeply loosen and turn over the soil, breaking up the compacted soil layer. This allows the residual film that was originally buried deep in the soil to be effectively turned over and exposed to the soil surface, thus creating favorable conditions for the subsequent picking-up component 2 to pick up the residual film, significantly improving the exposure rate and recyclability of the residual film.

[0035] like Figure 3 As shown, the pickup component 2 is arranged immediately behind the loosening soil structure 7. Figure 4 As shown, the pickup assembly 2 consists of a main rotating shaft 21 and multiple pickup units 22. The rotating shaft 21 is typically a solid or hollow cylindrical steel shaft, which is rotatably mounted on the support structures on both sides of the frame 1 via bearings, and its axis is parallel to the axle of the traveling wheel 6.

[0036] like Figure 3 Combination Figure 5 As shown, multiple pickup units 22 are evenly arranged in a ring on the circumferential surface of the rotating shaft 21, with the axis of the rotating shaft 21 as the center. The pickup assembly 2 is mechanically connected to the traveling wheel 6 through a transmission structure 23, such as through a chain, gear, or belt drive. When the traveling wheel 6 rotates, the transmission structure 23 transmits power to the rotating shaft 21, driving the rotating shaft 21 to rotate continuously around its own axis, thereby driving the multiple pickup units 22 on it to perform synchronous circular motion.

[0037] like Figure 4 As shown, each pickup unit 22 includes a mounting base 221 and multiple pickup teeth 222. The mounting base 221 is typically a rectangular or arc-shaped metal block, which is securely fixed to the radial outer surface of the rotating shaft 21 by means of welding, bolts, or keyways.

[0038] Multiple pickup teeth 222 are made of highly elastic and wear-resistant materials, such as spring steel or high-strength engineering plastics, and are elongated or hook-shaped. One end of each pickup tooth 222 is securely mounted on the mounting base 221 and extends outward along the radial direction of the mounting base 221.

[0039] To optimize pickup performance and increase coverage, the pickup teeth 222 on adjacent pickup units 22 are designed to be staggered rather than aligned in a straight line along the axial direction of the rotating shaft 21. This staggered arrangement allows different pickup teeth 222 to sequentially contact and comb the ground during the rotation of the rotating shaft 21, forming a continuous pickup trajectory with a wider axial coverage. This effectively captures residual film at different locations and depths, greatly improving the pickup efficiency and thoroughness of residual film.

[0040] like Figure 5 As shown, a scraper assembly 3 is arranged above and behind the pickup assembly 2. The scraper assembly 3 includes a bushing 31 and multiple plates 32. The bushing 31 is a cylindrical metal structure whose inner diameter is precisely matched with the outer diameter of the axle of the traveling wheel 6. Through splines, keyways, or interference fits, the bushing 31 is made coaxial with the axle of the traveling wheel 6 and rigidly arranged to ensure that it rotates synchronously with the axle of the traveling wheel 6.

[0041] Multiple plates 32, typically made of high-strength wear-resistant steel plates or polymer composite materials, are securely mounted on the circumferential sidewalls of the bushing 31 with their longer sides, forming a radially outward extending structure.

[0042] The plate 32 is arc-shaped, and its curvature precisely matches the trajectory of the pickup teeth 222 on the pickup unit 22 during circular motion. When the equipment is operating, the axle of the traveling wheel 6, through its connection with the bushing 31, directly drives the bushing 31 and the arc-shaped plate 32 mounted on it to perform circular motion. In the area where the movement trajectories of the plate 32 and the pickup teeth 222 of the pickup unit 22 intersect, a preset, precisely calculated gap is always maintained between the edge of the plate 32 and the pickup teeth 222. This gap forms a dedicated channel for the effective peeling of residual film from the pickup teeth 222.

[0043] When the pickup unit 22 carrying the residual film rotates to the intersection area with the arc-shaped plate 32, the arc-shaped plate 32 exerts a continuous and stable scraping force on the residual film on the pickup teeth 222. The scraping force causes the residual film to quickly detach from the surface of the pickup teeth 222 and, under the action of gravity and the arc-shaped guidance of the plate 32, smoothly slide down the smooth surface of the plate 32. The lower outlet direction of the scraper assembly 3 is precisely pointed to the inlet end of the conveying unit 4, thereby effectively guiding the peeled residual film to the conveying unit 4, ensuring the smooth transfer of the residual film and avoiding scattering and secondary contamination.

[0044] like Figure 3 and Figure 5 As shown, the inlet end of the conveying unit 4 is precisely located below the scraper assembly 3, and has a funnel-shaped or open trough-shaped structure. Its geometry and size are adapted to the outlet end of the scraper assembly 3 to effectively receive the residual film peeled off and guided down from the scraper assembly 3.

[0045] like Figure 5 As shown, the main components of the conveying unit 4 include a conveyor frame 41, a drive roller 42, a driven roller 43, and a conveyor belt 44. The conveyor frame 41 is a rectangular or trough-shaped support frame, usually welded from steel profiles, and is firmly installed in the designated position on the frame 1 by bolt connection, providing stable support for the conveying unit 4.

[0046] Both the driving roller 42 and the driven roller 43 are cylindrical drums, which are rotatably mounted at both ends of the conveyor frame 41 via bearings, and their axes are parallel to each other. The conveyor belt 44 wraps around the driving roller 42 and the driven roller 43 to form a continuous circulating conveying surface.

[0047] The conveyor belt 44 is typically made of high-strength, wear-resistant rubber or polyurethane material. Its inner surface is driven by friction or toothed meshing with the outer surfaces of the drive roller 42 and the driven roller 43. The drive roller 42 is powered by a motor, and its rotation drives the conveyor belt 44 to move continuously, thereby conveying the collected residual film along the length of the conveyor belt 44 from the inlet end to the outlet end.

[0048] To improve the purity of the residual film and effectively separate impurities, the surface of the conveyor belt 44 is precisely equipped with multiple impurity removal holes. These holes are evenly distributed in a matrix across the entire working surface of the conveyor belt 44. Each hole is typically circular, elliptical, or grooved, and its diameter is optimized to be precisely smaller than the typical size of residual film fragments, but larger than the size of major soil particles and small stones.

[0049] As the residual film moves on the conveyor belt 44, small impurities such as soil, sand, and pebbles attached to or mixed in the residual film can naturally fall off through these discharge holes during the movement and vibration of the conveyor belt 44, while larger fragments of the residual film are retained on the surface of the conveyor belt 44 and continue to be conveyed forward.

[0050] The conveying unit 4 further includes a vibration mechanism. This vibration mechanism is integrated into the structure of the conveying unit 4. The vibration mechanism mainly consists of an eccentric wheel and a drive shaft. The eccentric wheel is interference-fitted or keyed to the drive shaft via its central hole, thus securely fixed to the outside of the drive shaft. The center of gravity of the eccentric wheel is offset from its rotation center. When the drive shaft rotates at high speed under the drive of the motor, the eccentric wheel generates a periodic unbalanced force. This unbalanced force is transmitted to the conveyor frame 41 through the support structure, and then acts on the conveyor belt 44, causing the entire conveyor belt 44 to vibrate periodically up and down or left and right. This applies additional kinetic energy to the residual film on the conveyor belt 44, promoting further separation of the residual film from soil, dust, and other impurities adhering to its surface, enhancing the effect of impurities falling off through the discharge holes, and significantly improving the purity of the residual film.

[0051] like Figure 5As shown, the packaging unit 5 is located at the outlet end of the conveying unit 4, behind the frame 1, and is mainly composed of a support frame 51 and a packaging box 52.

[0052] The bottom of the support frame 51 may optionally be equipped with multiple casters 53. These casters 53 are typically omnidirectional or directional casters, with their bodies made of wear-resistant rubber or polyurethane material, and are connected to the bottom of the support frame 51 by pins or bolts. The arrangement of the casters 53 allows the packaging unit 5 to be moved or its position adjusted within a small range relative to the frame 1, facilitating unloading operations.

[0053] The packing box 52 is a rectangular or square container with a certain volume, usually welded from high-strength steel plates, with an opening at the top for receiving residual film. The packing box 52 is securely installed on top of the support frame 51 by bolting or welding.

[0054] The packing box 52 contains an internal compression mechanism. This mechanism includes a hydraulic cylinder and a pressure plate. The hydraulic cylinder, typically a double-acting cylinder, is securely mounted on the center of the top inner wall of the packing box 52 via bolts or welding. The piston rod of the hydraulic cylinder extends vertically downwards. The pressure plate, typically a rectangular or square thick steel plate matching the cross-sectional shape of the packing box 52, has its upper surface rigidly connected to the lower end of the piston rod of the hydraulic cylinder via threaded connections, pin connections, or flange connections.

[0055] When hydraulic oil is supplied to the hydraulic cylinder and the piston rod extends downwards, it drives the pressure plate downwards, applying tremendous downward pressure to the residual film accumulated inside the packaging box 52, thereby compressing the residual film into a dense package. When the hydraulic cylinder piston rod retracts, the pressure plate returns to its original position.

[0056] On the side wall of the packing box 52, typically at its bottom or middle, there is an openable unloading door. The unloading door is usually a hinged or sliding structure, and when closed, it tightly engages with the opening edge of the packing box 52 via a latch, latch, or hydraulic locking device to achieve a seal and secure fixation. After the residual film is compressed and packed, the unloading door can be opened to easily and quickly remove the packed residual film package from the packing box 52, facilitating subsequent transportation and storage.

[0057] When the residual film recycling and packaging equipment proposed in this embodiment is used, the rotating wheel 6 drives the rotating shaft 21 of the picking component 2 to rotate through the transmission structure 23. Multiple ring-shaped picking units 22 move synchronously with the rotating shaft 21. During the contact with the ground, they hook up and roll up the residual film in the field, completing the initial collection of residual film. The traveling speed needs to be controlled at 1.5-3km / h to avoid the picking unit 22 missing or the residual film getting tangled due to excessive speed.

[0058] Furthermore, as the equipment moves forward, the bushing 31 of the scraper assembly 3 rotates synchronously with the axle of the traveling wheel 6, causing the plate 32 to rotate continuously. When the picking unit 22 carrying the residual film rotates to the intersection with the plate 32, the edge of the plate 32 comes into close contact with the surface of the picking unit 22, forming a peeling channel. On the one hand, it scrapes off the soil particles adhering to the surface of the residual film, allowing the soil to fall directly back into the field. On the other hand, it guides the residual film after removing impurities to the inlet of the conveying unit 4 below, avoiding the accumulation of residual film.

[0059] This utility model is not limited to the specific technical solutions described in the above embodiments. Besides the above embodiments, this utility model may have other implementation methods. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
