Technical Field
[0001] This utility model belongs to the technical field of residual film picking and bundling integrated machine, specifically a high-efficiency residual film picking and bundling integrated machine. Background Technology
[0002] With the widespread application of plastic film mulching technology in agricultural production, a large amount of residual film remains in the soil for extended periods. This not only damages soil aggregate structure and hinders crop root development and water and nutrient absorption, but also leads to a decline in arable land quality and reduced crop yields. Furthermore, the residual film is difficult to degrade in the natural environment, creating "white pollution" that causes continuous harm to the ecological environment. Therefore, efficient recycling of residual agricultural film is a key measure to promote green agricultural development and ensure food security. The integrated residual film collection and bundling machine, as the core equipment for residual film recycling, directly determines the efficiency and quality of residual film recycling.
[0003] However, current residual film picking and baling machines on the market still face many technical bottlenecks in actual operation: First, the separation effect between residual film and impurities is poor. Existing equipment mostly adopts a single lifting structure, which makes it difficult to effectively separate large plant roots and stems (such as corn rootlets), large soil clods, stones and other impurities mixed in the residual film. This results in the impurity content of the residual film generally exceeding 10%, which not only increases the difficulty and cost of subsequent residual film processing, but also easily causes jamming and wear of internal components of the baling box, significantly increasing the equipment failure rate. Second, the adaptability is limited. The height of the traditional film lifting component is fixed, and it cannot be flexibly adjusted according to different laying methods such as flat film and furrow film. This often leads to problems such as missed picking or excessive soil penetration, affecting the integrity of picking. Third, the continuity of operation is insufficient. The film unloading mechanism of the baling box of some equipment relies on manual operation or simple mechanical transmission. The film unloading process is time-consuming and laborious, and the residual film bundles are prone to jamming, which seriously restricts the overall operation efficiency.
[0004] Therefore, a high-efficiency residual film picking and bundling machine is proposed to address the above problems. Utility Model Content
[0005] To address the problems mentioned in the background art, this utility model provides a high-efficiency residual film picking and bundling machine, which has the advantages of efficient picking of various residual films, accurate separation of impurities, low mechanical failure rate, convenient film unloading, high operating efficiency, and contributing to the green development of agriculture.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency residual film pickup and bundling machine, comprising a trailer tractor, an adjustable film shovel, a primary lifting conveyor assembly, a secondary lifting conveyor assembly, a front end of a bundling box, a rear end of a bundling box, a hydraulic cylinder, ground wheels, and depth-limiting wheels. The rear end of the trailer tractor is connected to a traction bridge, and the rear end of the traction bridge is connected to a gearbox. The adjustable film shovel is located below the front end of the primary lifting conveyor assembly, and a height adjustment mechanism is provided between the adjustable film shovel and the primary lifting conveyor assembly to adjust the height of the adjustable film shovel relative to the primary lifting conveyor assembly. The mechanism includes a primary lifting chain assembly with its discharge end connected to a secondary lifting chain assembly with its feed end. The secondary lifting chain assembly has film-lifting teeth. The feed end of the front end of the bundling box is connected to the discharge end of the secondary lifting chain assembly. The rear end of the front end of the bundling box is connected to the front end of the rear end of the bundling box via a hinge structure. One end of the hydraulic cylinder is hinged to the outer wall of the front end of the bundling box, and the other end is hinged to the outer wall of the rear end of the bundling box. The ground wheels are connected to both sides of the bottom of the machine via axles. The depth-limiting wheels are connected to the machine frame next to the adjustable film-lifting shovel via brackets.
[0007] Preferably, the output end of the gearbox is connected via sprockets to the secondary lifting drive sprocket of the secondary lifting chain assembly, the front drive sprocket of the bundling box, and the primary lifting drive sprocket of the primary lifting chain assembly.
[0008] Preferably, the lifting angle of the first-stage lifting chain assembly is 30° relative to the ground, the lifting angle of the second-stage lifting chain assembly is 63.5° relative to the ground, and the minimum horizontal gap between the first-stage and second-stage lifting chain assemblies is 170mm.
[0009] Preferably, a film rolling roller is rotatably connected inside the front end of the bundling box, and a rear end drive sprocket and a rear end driven sprocket are rotatably connected inside the rear end of the bundling box, and the rear end drive sprocket and the front end drive sprocket of the bundling box are connected by chain drive.
[0010] Preferably, the cylinder body of the hydraulic cylinder is hinged to the front end of the bundling box, and the piston rod of the hydraulic cylinder is hinged to the rear end of the bundling box. When the hydraulic cylinder retracts, the rear end of the bundling box rotates and rises around the hinge structure with the front end of the bundling box.
[0011] Preferably, a height adjustment screw that can adjust the height of the depth limiting wheel relative to the ground is connected between the depth limiting wheel and the bracket.
[0012] Preferably, the primary lifting chain assembly further includes a primary lifting transmission sprocket and a primary lifting tension sprocket that cooperate with the primary lifting drive sprocket. The primary lifting transmission sprocket and the primary lifting tension sprocket are rotatably connected to the machine frame via a rotating shaft, and the primary lifting chain is wound around the outside of the primary lifting drive sprocket, the primary lifting transmission sprocket, and the primary lifting tension sprocket. The secondary lifting chain assembly also includes a secondary lifting driven sprocket that cooperates with the secondary lifting drive sprocket. The secondary lifting driven sprocket is rotatably connected to the machine frame via a rotating shaft, and the secondary lifting chain is wound around the outside of the secondary lifting drive sprocket and the secondary lifting driven sprocket. The film picking teeth are evenly fixed on the outer chain plate of the secondary lifting chain.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves efficient pickup of residual film and precise separation of impurities through the coordinated design of an adjustable film shovel and a two-stage lifting chain assembly. The adjustable film shovel can be flexibly adjusted in height to adapt to different residual film laying methods such as flat film and furrow film, ensuring the integrity of residual film pickup from the source. The two-stage lifting chain assembly adopts differentiated lifting angles and a minimum horizontal gap of 170mm. After the first-stage lifting chain transports the residual film together with large roots, soil clods, stones and other impurities, the second-stage lifting chain uses a large-angle lifting and film-picking teeth to "selectively lift" the residual film, causing the impurities to fall off due to their own weight. This not only reduces the burden of subsequent residual film processing, but also avoids large impurities causing jamming and wear in the bundling box, significantly reducing the overall mechanical failure rate of the machine and extending the service life of the equipment. 2. The hydraulic linkage film unloading mechanism and adjustable structure of this utility model greatly improve the convenience and continuity of operation. The hydraulic cylinder drives the rear end of the baling box to rise around the hinge point, realizing the rapid and smooth unloading of residual film bundles without manual intervention, significantly improving the film unloading efficiency. The height adjustment function of the depth limiting wheel can flexibly control the film lifting depth according to the soil texture and the burial depth of the residual film, further optimizing the picking effect. The gearbox precisely transmits the transmission of each stage of the lifting chain and the baling box sprocket group through the sprocket, ensuring the synchronous operation of each component, making the entire process of picking, lifting, baling and unloading film efficiently connected. The overall operation efficiency is improved compared with traditional equipment, providing reliable support for large-scale farmland residual film recycling and contributing to the green and sustainable development of agriculture.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figures 1 to 3As shown, this utility model provides a high-efficiency residual film pickup and baling integrated machine, including a trailer tractor 1, an adjustable film shovel 2, a primary lifting chain assembly 3, a secondary lifting chain assembly 4, a baling box front end 5, a baling box rear end 6, a hydraulic cylinder 7, a ground wheel 8, and a depth-limiting wheel 9. The rear end of the trailer tractor 1 is connected to a traction bridge 10 for transmitting tractor traction power and providing a foundation for implement power connection. The rear end of the traction bridge 10 is connected to a secondary lifting drive sprocket 41 that drives the secondary lifting chain assembly 4, the baling box front end drive sprocket 51, and the primary lifting drive sprocket 31 of the primary lifting chain assembly 3, respectively, through sprockets, ensuring the smooth operation of each transmission component. A gearbox 11 synchronizes power to coordinate the "pick-up-lift-bundle" process; an adjustable film shovel 2 is located below the front end of the primary lifting chain assembly 3, and a height adjustment mechanism is provided between the adjustable film shovel 2 and the primary lifting chain assembly 3 to flexibly adapt to different residual film laying forms such as flat film and furrow film, improving the integrity and adaptability of residual film pickup; the discharge end of the primary lifting chain assembly 3 is connected to the feed end of the secondary lifting chain assembly 4, and the lifting angle of the primary lifting chain assembly 3 is 30° relative to the ground, which can stably transport residual film, large plant roots, large soil clods, stones and other materials dug up by the film shovel to the secondary lifting chain assembly 4; the lifting of the secondary lifting chain assembly 4... The angle relative to the ground is 63.5°, and the minimum horizontal gap between the primary lifting chain assembly 3 and the secondary lifting chain assembly 4 is 170mm. Utilizing the angle difference between the two stages of lifting, large plant roots, stones, and large clods of soil cannot be lifted by the secondary lifting chain assembly 4 due to their own weight and thus fall off, achieving separation of residual film and impurities. The secondary lifting chain assembly 4 is equipped with film-picking teeth 12 that can precisely "grab" and lift the residual film, further ensuring efficient delivery of the residual film to the bundling box and reducing the impurity content of the residual film to about 3%. The feed end of the front end 5 of the bundling box is connected to the discharge end of the secondary lifting chain assembly 4, and the rear end of the front end 5 of the bundling box is connected to the front end of the rear end 6 of the bundling box via a hinge. The hydraulic cylinder 7 is hinged at one end to the outer wall of the front end 5 of the bundling box and at the other end to the outer wall of the rear end 6 of the bundling box. When the hydraulic cylinder 7 retracts, the rear end 6 of the bundling box rotates and rises around the hinged structure, realizing the rapid and smooth unloading of residual film bundles without manual intervention, thus improving the unloading efficiency. The ground wheel 8 is connected to both sides of the bottom of the machine through axle, providing walking support for the machine and ensuring its stability. The depth limiting wheel 9 is connected to the machine frame next to the adjustable film shovel 2 through a bracket, and there is a height adjustment screw between the depth limiting wheel 9 and the bracket, which can flexibly control the soil depth of the adjustable film shovel 2 according to the soil texture and the burial depth of the residual film, thus optimizing the residual film picking effect.
[0018] Specifically, the output end of the gearbox 11 is connected to the secondary lifting drive sprocket 41 of the secondary lifting chain assembly 4, the front drive sprocket 51 of the front end of the bundling box 5, and the primary lifting drive sprocket 31 of the primary lifting chain assembly 3 via sprockets, thereby providing power to the secondary lifting chain assembly 4, the sprocket group of the front end of the bundling box 5, and the primary lifting chain assembly 3, ensuring the synchronous operation of each component.
[0019] Furthermore, the lifting angle of the primary lifting chain assembly 3 is 30° relative to the ground, and the lifting angle of the secondary lifting chain assembly 4 is 63.5° relative to the ground. The minimum horizontal gap between the primary lifting chain assembly 3 and the secondary lifting chain assembly 4 is 170mm. This differentiated angle and gap design is the key to achieving efficient separation of residual film and impurities. It ensures that the residual film is effectively lifted by the film picking teeth 12 on the secondary lifting chain assembly 4, while preventing large impurities from entering the bundling box due to their angle and weight, thus reducing bundling box malfunctions.
[0020] Furthermore, a film rolling roller is rotatably connected inside the front end 5 of the bundling box, and a rear end drive sprocket 61 and a rear end driven sprocket 62 of the bundling box are rotatably connected inside the rear end 6 of the bundling box. The rear end drive sprocket 61 and the front end drive sprocket 51 of the bundling box are connected by chain drive, so that the sprocket groups at the front and rear ends of the bundling box operate synchronously, providing stable power for bundling residual film.
[0021] It is worth noting that the cylinder body of the hydraulic cylinder 7 is hinged to the front end 5 of the bundling box, and the piston rod of the hydraulic cylinder 7 is hinged to the rear end 6 of the bundling box. When the hydraulic cylinder 7 retracts, the rear end 6 of the bundling box rotates and rises around the hinge structure with the front end 5 of the bundling box. This hydraulic linkage unloading method is more efficient and convenient than the traditional manual unloading method, ensuring the continuity of the operation process.
[0022] It is worth noting that there is an adjustable screw connecting the depth limiting wheel 9 to the support, which can adjust the height of the depth limiting wheel 9 relative to the ground. By rotating the screw, the height of the depth limiting wheel 9 can be flexibly adjusted, thereby precisely controlling the soil penetration depth of the adjustable film shovel 2 and adapting to the needs of residual film collection under different farmland conditions.
[0023] It is worth mentioning that the primary lifting chain assembly 3 also includes a primary lifting transmission sprocket 32 and a primary lifting tension sprocket that cooperate with the primary lifting drive sprocket 31. Both the primary lifting transmission sprocket 32 and the primary lifting tension sprocket are rotatably connected to the machine frame via a rotating shaft. The primary lifting chain is wound around the outside of the primary lifting drive sprocket 31, the primary lifting transmission sprocket 32, and the primary lifting tension sprocket, ensuring stable transmission and tension of the primary lifting chain and preventing chain loosening from affecting material conveying. The secondary lifting chain assembly 4 also includes... The secondary lifting drive sprocket 41 is matched with the secondary lifting driven sprocket. The secondary lifting driven sprocket is rotatably connected to the machine frame via a rotating shaft. The secondary lifting chain is wrapped around the outside of the secondary lifting drive sprocket 41 and the secondary lifting driven sprocket. The film picking teeth 12 are evenly fixed on the outer chain plate of the secondary lifting chain. This allows the secondary lifting chain to operate stably while efficiently "grabbing" and lifting the residual film through the film picking teeth 12, achieving precise separation of residual film and impurities. This ensures that the residual film entering the bundling box has a low impurity rate and reduces the risk of bundling box failure.
[0024] Working principle and process: The trailer 1 is connected to the tractor. The tractor's power is transmitted to the gearbox 11 via the traction bridge 10. The gearbox 11 drives the secondary lifting drive sprocket 41 of the secondary lifting chain assembly 4, the front drive sprocket 51 of the baling box front end 5, and the primary lifting drive sprocket 31 of the primary lifting chain assembly 3 to operate synchronously. The adjustable film shovel 2, with the cooperation of the depth limiting wheel 9, picks up the residual film on the ground. Then, the residual film and mixed large plant roots, large soil clods, etc. are transported to the primary lifting chain assembly 3. The primary lifting chain assembly 3 transports the material to the secondary lifting chain assembly 4 at a 30° angle. The chain assembly 4 operates at a 63.5° angle. The film-picking teeth 12 on its chain grab the residual film and lift it upwards, while large impurities fall down because they cannot be lifted due to the large angle and their own weight. This achieves the separation of residual film and impurities. The separated residual film enters the front end 5 of the bundling box. It is bundled by the cooperation of the internal film-winding roller and the rear end drive sprocket 61 and the rear end driven sprocket 62 of the bundling box. Finally, the hydraulic cylinder 7 retracts, driving the rear end 6 of the bundling box to rise around the hinge structure with the front end 5 of the bundling box, unloading the residual film bundle. The ground wheel 8 supports the stable movement of the whole machine, completing the complete operation process of "picking up - lifting and separating - bundling - unloading film".
