Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, specifically to an integrated machine for recycling residual film and returning straw to the field. Background Technology

[0002] Due to its advantages such as high yield, increased temperature and moisture retention, plastic film mulching technology has been widely promoted and applied in Xinjiang. However, the residual film after use has not been effectively recycled year after year, causing serious residual film pollution in farmland.

[0003] In order to solve the serious white pollution problem caused by the increased use of plastic film, more and more people have begun to develop and research machinery for picking up and recycling residual film in order to solve the problems of low efficiency, low recovery rate, high labor intensity and high cost of manual recycling.

[0004] In addition, returning crushed crop straw to the field helps increase soil organic matter and nutrient content, improves soil physical properties, and enhances soil biological activity, resulting in a significant yield increase. However, returning crushed crop straw to the field is a labor-intensive, time-consuming, and highly seasonal operation. If crop straw is not processed in a timely manner, it will affect autumn plowing and restrict spring sowing the following year. Currently, straw crushers are used to crush crop straw and return it to the field, which is then plowed and buried in the soil.

[0005] After crop harvest, residual plastic film on the ground needs to be removed promptly to facilitate the growth of crops the following year. Currently, the main method used is a toothed mulch rake, which uses the principle of a straw rake to gather the residual film into piles or strips, and then loads it onto trucks for removal from the field. This method easily removes the crushed straw that has been returned to the field at the same time, negating the effect of straw return, and also has a low residual film removal rate and productivity.

[0006] In existing technologies, the tasks of cleaning the plastic film and crushing and returning straw to the field are performed separately, resulting in numerous operations and high power consumption. To achieve the combined operation of straw crushing and returning to the field and residual plastic film recycling in a single operation, reducing operational steps and lowering production costs, this invention provides a machine that combines residual plastic film collection, baling and recycling with straw crushing and returning to the field, enabling integrated operation and multi-purpose functionality. Summary of the Invention

[0007] The purpose of this invention is to provide a structurally sound and economically practical integrated machine for recycling residual film and returning straw to the field. It can achieve combined operations of picking up, recycling, and baling residual film, as well as crushing and returning straw to the field, making it a multi-purpose machine. During use, the residual film picking roller, with its lighter load during the picking process, effectively increases the overall flexibility of the picking roller, greatly improving the efficiency of residual film picking. The dedicated suspension traction frame solves the problem of the small angle between the power input and the drive shaft, which is detrimental to the rearward transmission of the machine, allowing for flexible connection, steering, and transmission between the traction machine and the operating agricultural machinery. The multiple gearbox design and clutch sprocket design in the transmission device result in rapid deceleration and stable transmission, ensuring the coordinated and normal operation of all components of the machine.

[0008] This invention discloses an integrated machine for recycling residual film and returning straw to the field, including a main frame, a traction frame, and traveling wheels. The main frame is equipped with a lever device, a residual film picking roller, a baling device, and a transmission device. The residual film picking roller includes a track plate device, a roller body, a central transmission shaft, a shaft plate, roller side plates, a film picking spring tooth assembly, a film picking crank, and a crank roller. The roller body has roller side plates on both sides and a shaft plate in the middle. The film picking spring tooth assembly has multiple sets, spaced circumferentially around the outer ring of the roller body. The track plate device has an annular track. One end of the film picking crank is connected to the spring tooth main shaft in the film picking spring tooth assembly, and the other end is connected to the crank roller. The crank roller is placed in the annular track and can roll within the annular track.

[0009] Each group of film-picking spring teeth includes a spring tooth main shaft, a spring tooth connecting shaft, and film-picking spring teeth. One end of the spring tooth main shaft is connected to the shaft disk through a bearing, and the other end is connected to the roller side plate through a bearing. Each spring tooth main shaft is provided with a spring tooth connecting shaft, and each spring tooth connecting shaft is provided with multiple film-picking spring teeth at intervals.

[0010] The track plate device mainly includes an end plate, an inner rail assembly, and an outer rail assembly. The inner rail assembly and the outer rail assembly are both fixedly connected to the end plate. The inner rail assembly is located inside the outer rail assembly. The inner rail assembly and the outer rail assembly are spaced apart to form an irregularly shaped ring track.

[0011] In the structure of the track plate device, the inner rail assembly includes an upper inner rail plate and a middle inner rail plate. The upper inner rail plate and the middle inner rail plate have the same shape, both being irregular ring-shaped plates. The middle inner rail plate, the upper inner rail plate, and the end plate are fixed together by bolts, and spacer sleeves are provided on the bolts, so that the middle inner rail plate, the upper inner rail plate, and the end plate are spaced apart by a distance.

[0012] The outer rail assembly includes an upper outer rail plate and a middle outer rail plate. The upper outer rail plate and the middle outer rail plate have the same shape, both being irregular ring-shaped plates. The middle outer rail plate, the upper outer rail plate, and the end plate are fixed together by bolts, and spacer sleeves are provided on the bolts, so that the middle outer rail plate, the upper outer rail plate, and the end plate are spaced apart by a distance.

[0013] In the aforementioned track plate device structure, the bolts are divided into long mounting bolts and short mounting bolts. The long mounting bolts extend outward for fixing the end plate to the main frame.

[0014] The aforementioned traction frame mainly comprises a main support, a suspension connecting frame, and a U-shaped connecting support. One end of the U-shaped connecting support is hinged to the middle of the suspension connecting frame, and the other end of the U-shaped connecting support is hinged to the main support. The U-shaped connecting support is provided with a "п"-shaped slide block above it, and the "п"-shaped slide block is provided with a strip-shaped sliding groove. The main support is provided with a transmission support near the end of the U-shaped connecting support. The transmission support is divided into an upper support and a lower support. Both the upper support and the lower support are tubular cylinders. The lower support is provided with a rotating shaft. The upper part of the rotating shaft is connected to the lower support through a bearing, and the lower part of the rotating shaft is fixedly connected to the main support. The upper support is arranged horizontally and is provided with a transmission coupling inside. The transmission coupling is connected to the upper support through a bearing.

[0015] The transmission support has a forward-extending sliding wall at the front, and a pulley at the front end of the sliding wall. The pulley extends into the strip groove on the "п"-shaped slide block, and the pulley can slide back and forth in the strip groove.

[0016] The transmission support is provided with a shock-absorbing seat at the rear, and a shock-absorbing block is provided at the front end of the shock-absorbing seat. The shock-absorbing block extends forward and makes elastic contact with the outer wall of the lower support.

[0017] In the aforementioned traction frame structure, reinforcing ribs are provided on the sliding wall; the shock-absorbing seat is a tubular cylinder, the shock-absorbing block is connected to a block seat, the block seat is slidably connected to the inner wall of the shock-absorbing seat, and the upper and rear parts of the shock-absorbing seat are provided with tightening nuts, the tightening nuts pass through the outer wall of the shock-absorbing seat, contact the block seat, and tighten the block seat downward and forward.

[0018] In the aforementioned traction frame structure, the shock-absorbing block is made of elastic material; the contact surface between the shock-absorbing block and the outer wall of the lower support is arc-shaped.

[0019] The straw-throwing device is located at the front end of the main frame. Its structure includes a throwing air duct, which is a flat, canopy-shaped air duct that extends backward to cover the top of the machine. Its function is to throw the crushed straw to the rear of the machine.

[0020] The residual film pickup roller is located behind the boom-starting device, with a windproof curtain between them. The windproof curtain includes a baffle plate, a baffle plate crossarm, and a curtain plate seat. The baffle plate is a folded plate, and the baffle plate crossarm is located at the upper end of the baffle plate and connected to the main frame through the curtain plate seat. The function of the windproof curtain is to prevent the airflow driven by the boom-starting device in front from affecting the pickup operation of the residual film pickup roller behind it.

[0021] The transmission device includes a locomotive speed input end, drive shaft I, a rod-beating device gearbox, a bridge gearbox, drive shaft II, a residual film picking roller gearbox, a fan input sprocket, a fan output sprocket, a bridge seat, a clutch sprocket, a bridge shaft, and a packaging device input sprocket. External power is transmitted to drive shaft I through the locomotive speed input end. Drive shaft I is connected to the rod-beating device gearbox, and then transmitted to the bridge gearbox via a belt. The bridge gearbox then transmits power to the residual film picking roller gearbox via drive shaft II, and then to the residual film picking roller sprocket via a chain drive. After speed change, the power is output to the fan input sprocket. The power is then transmitted to the packaging device input sprocket in sequence via the fan output sprocket, the bridge seat, the clutch sprocket, and the bridge shaft.

[0022] This invention utilizes gearbox reduction to overcome the limitations of commonly used belt drive designs, which often involve slow deceleration, requiring several stages to reduce speed. This process is slow and the structural design is complex. The design allows for one-step gearbox reduction, greatly simplifying the combined design of the transmission device.

[0023] The clutch sprocket in the transmission device includes a single-row sprocket and a clutch disc. The diameter of the clutch disc is smaller than the diameter of the single-row sprocket. The clutch disc is fixedly sleeved with the bridge shaft. The single-row sprocket has multiple connecting bolt holes around its shaft hole. The clutch disc also has multiple bolt holes at corresponding positions. The single-row sprocket and the clutch disc are coaxially engaged and connected by bolts. The number of bolts is less than the number of bolt holes, so that when subjected to stress overload or stress instability, the connecting bolts between the single-row sprocket and the clutch disc will disconnect, ensuring that the connection between the single-row sprocket and the clutch disc is broken.

[0024] The clutch sprocket plays a crucial role in protecting machine components: during the packing operation, when the packing device at the rear is overloaded, the operation must be stopped in time. If it is not stopped in time, it will cause wear and damage to the components. At this time, the connecting bolt between the single row sprocket and the clutch disc is broken, causing it to spin freely, and the packing device stops working, effectively avoiding damage to the mechanical parts.

[0025] Preferably, the single-row sprocket is connected to the clutch disc by bolts, and the number of bolts is 2-4.

[0026] Preferably, two sets of depth-limiting rollers are provided below the main frame, located behind the striking device and behind the residual film picking roller, respectively.

[0027] Working principle of this invention: This invention integrates straw cutting and returning to the field, residual film collection, and residual film recycling and packaging into one unit, realizing the combined operation of residual film collection, recycling and packaging, and straw crushing and returning to the field. In the overall machine design, existing straw-breaking devices and residual film packaging devices can be used.

[0028] In the prior art, there exists a toothed residual film picking roller that uses a drive device to rotate a toothed mounting rod. This drive device includes a track disc or cam disc driving a crank or crank arm mechanism, ultimately causing the picking teeth mounted on the toothed mounting rod to rotate. The track disc is an integrally enclosed disc, resulting in a relatively heavy overall weight, which increases the overall weight of the toothed recycling picking device. During the picking process, when the soil is wet or contains a large amount of sand and gravel, the resistance encountered during ground operation is significant, placing a heavy burden on the entire residual film recycling machine and reducing its flexibility, further lowering the efficiency of residual film recycling operations. To address the shortcomings of the prior art, a lighter residual film picking roller is provided, which can improve the residual film picking efficiency of the entire residual film recycling machine.

[0029] The residual film pickup roller disclosed in this invention comprises a roller body, a central drive shaft, a shaft disc, a roller side plate, a pickup spring tooth assembly, a pickup crank, and a crank roller; the track disc device is used in conjunction with the pickup crank and crank roller on the roller body.

[0030] The residual film picking roller of this invention is equipped with multiple sets of film-collecting spring teeth, and a drive sprocket is connected to the central drive shaft. Multiple crank rollers on the film-collecting cranks are embedded in the annular track of the track disc device. When the film recycling machine is running, the drive sprocket is subjected to force, driving the picking roller to rotate. The film-collecting cranks run within the annular track of the track disc device, the direction of the film-collecting spring teeth is controlled by the film-collecting cranks, and the track disc device controls the running trajectory of the film-collecting cranks.

[0031] The residual film picking roller disclosed in this invention is equipped with a track disk device, the structure of which mainly includes an end plate, an inner rail assembly, and an outer rail assembly. The inner rail assembly and the outer rail assembly are both composed of irregular ring-shaped multi-layer plates. The ring formed by the inner rail assembly is smaller than the ring formed by the outer rail assembly and is located inside the outer rail assembly. The inner rail assembly and the outer rail assembly are separated by a distance, and the space between them forms a ring track.

[0032] The inner rail assembly comprises an upper inner rail plate and a middle inner rail plate. The upper and middle inner rail plates have the same shape, both being irregular ring-shaped plates. The upper and middle inner rail plates are separated from the end plate by spacers and are fixedly connected to the end plate by continuous bolts. Similarly, the outer rail assembly comprises an upper outer rail plate and a middle outer rail plate. The upper and middle outer rail plates have the same shape, both being irregular ring-shaped plates. The middle outer rail plate, the upper outer rail plate, and the end plate are provided with spacers and are fixed to the end plate by continuous bolts.

[0033] To address the problems of low film collection efficiency and excessive weight in existing residual film recycling machines, this invention proposes a rationally designed and economically practical track disc device. The device features a multi-layered design, resulting in a lighter overall weight. Combined with the residual film picking roller, this design reduces the load during picking, effectively increasing the roller's overall flexibility and significantly improving the efficiency of residual film collection. The provided residual film picking roller, in conjunction with the lightweight track disc device, reduces the resistance of the machine's movement, effectively improving the efficiency of film collection and demolding operations. This enhances the overall efficiency and economic practicality of the residual film recycling and straw return machine.

[0034] The overall structure of this invention also includes a traction frame structure, which is an agricultural vehicle traction frame. It mainly includes a main support, a suspension connecting frame, and a U-shaped connecting support. One end of the U-shaped connecting support is hinged to the middle of the suspension connecting frame, so that the left and right sides of the suspension connecting frame can swing up and down around the fixing bolt. The other end of the U-shaped connecting support is hinged to the main support, and the main frame can rotate around the hinge axis.

[0035] The U-shaped connecting support is provided with a "п"-shaped slide block above it. The "п"-shaped slide block is provided with a strip-shaped slide groove. The pulley at the front end of the slide wall extends into the strip-shaped slide groove on the "п"-shaped slide block. The pulley can slide back and forth in the strip-shaped slide groove. The transmission support is provided with a rotating shaft inside. The transmission support and the main frame are hinged through the rotating shaft.

[0036] When the traction locomotive turns, the suspension connecting frame rotates the U-shaped connecting support together with it at a certain angle, forming a turning angle with the main frame. The entire transmission support is hinged to the main frame at the bottom via a pivot shaft, and the upper transmission shaft I16 is connected to the transmission coupling shaft. The pulleys on the sliding arm can slide back and forth in the strip groove. When the suspension connecting frame rotates the U-shaped connecting support together, the upper transmission support rotates, causing the pulleys to slide in the strip groove, which in turn causes the transmission coupling shaft to rotate the transmission shaft I16, forming a transmission angle.

[0037] When the agricultural vehicle turns, the suspension connecting frame drives the U-shaped connecting support to rotate, forming a rotation angle with the main frame. The transmission support drives the sliding arm to form another rotation angle with the main frame. The transmission coupling on the transmission support rotates with the transmission shaft I16 to form yet another rotation angle. This creates a large transmission angle between the vehicle and the transmission shaft in the entire power input direction. Compared with the prior art, when the agricultural vehicle turns the same angle, this invention ensures a larger transmission angle, greatly reducing the impact of the vehicle's turning on the transmission stability of the transmission shaft I16.

[0038] The transmission support is provided with a shock-absorbing seat at the rear, and a shock-absorbing block is provided at the front end of the shock-absorbing seat. The shock-absorbing block is made of elastic material and extends forward to elastically contact the outer wall of the lower support. The purpose is to use the shock-absorbing block to contact the lower support, forming frictional resistance, so that the entire transmission support rotates more smoothly and plays a role in shock absorption.

[0039] The towing frame in this invention features a simple, economical, and practical design. This design effectively cushions the lateral sway of the tractor and the connecting frame of the agricultural machinery. Especially during turns, the intermediate connection between the U-shaped connecting support and the transmission support ensures that the transmission angle is not too small when the tractor makes a large turn, minimizing the impact on the transmission shaft. This effectively solves the problem of traditional towing equipment where the connecting towing frame cannot change the rear transmission angle, affecting the rear transmission when the tractor makes a large turn. It eliminates the limitation of the transmission angle caused by the tractor's turn, allowing for a larger transmission angle, resulting in more stable transmission, improved overall performance of the agricultural machinery, greater adaptability, and significantly enhanced operational stability.

[0040] Compared with existing technologies, the integrated machine for residual film recycling and straw return provided by this invention has a reasonable structure, is economical and practical, and can realize the combined operation of residual film collection, recycling and baling, and straw crushing and return to the field, making it a multi-purpose machine. During use, the residual film collection roller is less burdened during the collection process, which can effectively increase the overall flexibility of the collection roller and greatly improve the efficiency of residual film collection. The use of a dedicated suspension traction frame solves the problem of the small angle between the power input and the transmission shaft, which is not conducive to the rearward transmission of the locomotive, and allows for flexible connection, steering and transmission between the traction locomotive and the operating agricultural machinery. The design of multiple gearboxes and clutch sprockets in the transmission device makes the transmission deceleration faster and ensures the stable operation of each equipment component, making it suitable for large-scale promotion and use.
