Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and is an integrated machine for straw return to the field and residual film recycling in round bales. Background Technology

[0002] Nowadays, mulch cultivation technology is widely used in various regions, especially in arid areas. With its significant advantages such as increasing temperature, conserving moisture, suppressing weed growth, promoting early maturity of crops, and increasing yield, mulch cultivation technology has indeed brought benefits to farmers. However, if the old plastic film used for cultivation is not recycled in a timely and effective manner, it will cause soil compaction and degradation, hinder crop germination, cause a rapid decline in soil quality and reduced utilization efficiency, and bring serious white pollution to the environment, becoming a major environmental hazard.

[0003] Currently, several types of residual film recycling machines have been developed both domestically and internationally, mainly including nail-tooth type, toothed chain type, and rake-tooth type residual film recycling machines. The operation process mainly includes film lifting, film picking, film winding, and film unloading. Among them, film lifting is the first step in the residual film recycling process, and the effectiveness of film lifting affects the recycling rate. For nail-tooth type residual film recycling machines, the film lifting device, as the film lifting component of the whole machine, is affected by the aging of the film and the easy clogging of the film lifting device by crop straw and other impurities during operation. This makes the film lifting effect of the film lifting device not obvious, and the impurities clogging the film lifting device are difficult to remove. Every once in a while, the film lifting device needs to be cleaned manually. At the same time, the collected residual film has a lot of soil and sand attached to it, which can easily damage the spring teeth and increase the failure rate.

[0004] In addition, the land is uneven due to the presence of ridges, ditches, and mounds. When walking on uneven land, the soil-penetrating mechanism of the residual film recovery device can easily leave residual film behind, reducing the recovery rate. During the residual film removal process, in order to make the film-lifting device adapt to the ground conditions and ensure the working depth without missing any residual film, when the machine body is long and wide, i.e., the entire frame is large, such as when the ground surface is undulating and has slopes, the film-lifting device cannot move up and down with the undulations of the ground. This will cause the working parts to not penetrate the soil in some places or not penetrate the soil deep enough, resulting in missing residual film and a low film-lifting rate. Summary of the Invention

[0005] This invention provides a round bale machine for recycling residual film from straw returning to the field, which overcomes the shortcomings of the existing technology. It can effectively solve the problems of impurities that are difficult to discharge and low film removal rate in existing residual film recycling machines that are congested at the film-raising device.

The straw crushing component, the first conveying auger, and the residual film baling assembly are installed on the frame at intervals from front to back. The film lifting assembly is hinged to the frame at the position corresponding to the position between the first conveying auger and the residual film baling assembly. The straw crushing component is used to crush the straw stubble and throw it into the first conveying auger. The first conveying auger transports the crushed straw stubble to both sides of the frame. The film lifting assembly can rise and fall with the ground height and lift the residual film from the ground and transport it to the residual film baling assembly.

Detailed Implementation

[0034] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0035] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as front, back, top, bottom, left, right, etc. The positional relationships are determined based on the layout direction of the attached diagram in the instruction manual.

[0036] The present invention will be further described below with reference to embodiments and accompanying drawings: Example 1: As shown in the attached document Figures 1 to 8As shown in Figure 13, the straw returning to the field and residual film recycling round baler includes a straw crushing component, a first conveying auger 2, a film lifting assembly, a residual film baling assembly, a frame 1, and a drive assembly. The straw crushing component, the first conveying auger 2, and the residual film baling assembly are installed on the frame 1 at intervals from front to back. The film lifting assembly is hinged to the frame 1 at the position between the first conveying auger 2 and the residual film baling assembly. The straw crushing component is used to crush the straw stubble and throw it into the first conveying auger 2. The first conveying auger 2 transports the crushed straw stubble to both sides of the frame 1. The film lifting assembly can rise and fall with the ground height and lift the residual film from the ground and transport it to the residual film baling assembly. The baling assembly is used to roll the residual film into a cylindrical shape. The drive assembly is installed on the upper front side of the frame 1. The drive assembly is connected to the straw crushing component, the first conveying auger 2, the film lifting assembly, and the residual film baling assembly. The rear of the frame 1 is provided with transport wheels 3.

[0037] In use, the front of the frame 1 is mounted to the tractor via a towing frame. The output shaft at the rear of the tractor is connected to the input shaft of the drive assembly. As the frame 1 moves forward with the tractor, the tractor's output shaft drives the straw crushing assembly, the first conveying auger 2, the film lifting assembly, and the residual film baling assembly via the drive assembly. When the straw crushing assembly is working, it crushes the straw stubble and throws it into the first conveying auger 2. Then, the first conveying auger 2 transports the crushed straw stubble to both sides of the frame 1. When the film lifting assembly is working, it lifts the residual film from the ground and transports it to the residual film baling assembly. Finally, the residual film baling assembly... The baling assembly winds the residual film into a cylindrical shape, enabling centralized recycling of the residual film. A film lifting assembly is hinged to the frame 1, corresponding to the position between the first conveying auger 2 and the residual film baling assembly. This film lifting assembly can lift the residual film from the ground according to the undulations of the ground, adapting to uneven ground. The transport wheels 3 facilitate the rapid transfer of the straw returning to the field residual film recycling round baler on the road. This allows the residual film in the ground to be quickly cleaned and wound into bales, facilitating subsequent centralized processing, reducing the labor intensity in the residual film recycling process, and improving the efficiency of straw crushing and residual film recycling.

[0038] The above-mentioned straw return-to-field residual film recycling round baler can be further optimized and / or improved according to actual needs: Example 2: As an optimization of the above examples, as shown in the appendix. Figure 1 , 2As shown in Figures 3, 5 to 13, the film-forming assembly includes a mounting frame 4, a central shaft 5, a film-taking roller, film-taking components, and a floating plate. A connecting cylinder is rotatably mounted on the upper part of the frame 1, corresponding to the position in front of the transport wheel 3. The connecting cylinder is fixedly mounted to the upper part of the mounting frame 4. A central shaft 5 is rotatably mounted on the inner side of the lower part of the mounting frame 4. A film-taking roller is fixedly mounted on the outer side of the central shaft 5. Several film-taking components are evenly distributed around the outer circumference of the film-taking roller. Each film-taking component includes several film-taking blades fixedly mounted on the outer side of the film-taking roller at left and right intervals. A left guide rail 6 and a right guide rail 7 with identical structures are detachably fixedly mounted on the left and right sides of the mounting frame 4, corresponding to the positions between two adjacent film-taking components. A floating plate is hinged to the outside of the film-taking roller. The surface of the floating plate away from the central axis 5 has a film-removing hole corresponding to the film-taking knife. The right side of the left guide rail 6 and the left side of the right guide rail 7 are provided with annular guide grooves 8. There are separation points 9 and film-taking points 10 in the guide grooves 8. Each guide groove is provided with a guide wheel 11 that is rotatably installed with the floating plate at the corresponding position. When the guide wheel 11 moves from the film-taking point 10 to the separation point 9 along the guide groove 8 with the central axis 5, the end of the film-taking knife gradually retracts into the corresponding film-removing hole. When the guide wheel 11 moves from the separation point 9 to the film-taking point 10 along the guide groove 8 with the central axis 5, the end of the film-taking knife gradually extends out from the corresponding film-removing hole.

[0039] Depending on the requirements, the guide wheel 11 can be made of existing known technology, such as a rolling bearing. In use, the front of the frame 1 is hinged to the tractor, so that the lower end of the mounting frame 4 can float up and down as the traction equipment moves forward, and can collect and recycle residual film in the soil according to the ground level. The drive assembly is connected to the tractor's drive shaft 47 by existing known technology, such as by universal joint and gearbox transmission.

[0040] During residual film recycling, the tractor pulls the frame 1 forward, and the tractor's output shaft drives the central shaft 5 to rotate. The central shaft 5 rotates counterclockwise, and the blade of the lowest film-taking knife inserts into the soil to pick up the residual film in the soil layer. As the guide wheel 11 rotates with the central shaft 5, it moves along the guide groove 8 from the film-taking point 10 to the separation point 9. The blade of the film-taking knife gradually retracts into the corresponding demolding hole. When the roller moves to the separation point 9, the film-taking knife is completely retracted into the demolding hole. At this time, the inner wall of the demolding hole can scrape off the residual film attached to the film-taking knife. The scraped residual film slides down the floating plate to the rear and enters the residual film bundling assembly, where it is wound into a cylindrical shape for centralized recycling. The guide wheel 11 continues along the guide groove 8 with the central shaft 5. As the machine moves from separation point 9 to film collection point 10, the end of the film collection knife gradually extends out of the corresponding film removal hole. When the guide wheel 11 moves to film collection point 10, the blade of the film collection knife fully extends out of the film removal hole. At this time, the blade of the film collection knife inserts into the residual film in the soil. As the central shaft 5 continues to rotate, the film collection assembly and the floating plate can continuously lift and separate the residual film in the soil. The left and right sides of the frame 1 are detachably and fixedly equipped with the left guide rail 6 and the right guide rail 7 with the same structure. This makes it easy to adjust the left guide rail 6 and the right guide rail 7, thereby adjusting the position of separation point 9 and film collection point 10. This allows the lower part of the frame 1 to still achieve residual film recovery during the up and down floating process, which can avoid the phenomenon that residual film is blocked on the film collection knife and difficult to discharge during the film removal operation, thus improving the film removal rate.

[0041] Example 3: As an optimization of the above examples, as shown in the appendix. Figure 2 , 3 As shown in Figures 5, 6, 9 to 13, the film-taking roller includes a first cutter disc 12 and a second cutter disc 13. Several first cutter discs 12 are installed at intervals on the outer side of the central shaft 5. At least one second cutter disc 13 is fixedly installed at intervals between each pair of adjacent first cutter discs 12. Each second cutter disc 13 is fitted onto the outer side of the central shaft 5. The film-taking blade includes a first blade 14, a second blade 15, a third blade 16, and a fourth blade 17. At least two first blades 14 are evenly distributed along the circumference on the left end of each first cutter disc 12. A second blade 15 is fixedly installed on the right end of the first cutter disc 12 at the position between two adjacent first blades 14. Several third blades 16 are evenly distributed along the circumference on the left end of the second cutter disc 13. A fourth blade 17 is fixedly installed on the right end of the second cutter disc 13 at the position between two adjacent third blades 16.

[0042] During operation, each first cutter disc 12 has two first blades 14 evenly distributed circumferentially on its outer side. A second blade 15 is fixedly installed on the outer side of each first cutter disc 12 between adjacent first blades 14. Two third blades 16 are fixedly installed on the left end of the second cutter disc 13, and two fourth blades 17 are fixedly installed on the right end of the second cutter disc 13. This symmetrical installation of the blades on the left and right ends of the first and second cutter discs 12 and 13 ensures more even force distribution on the central shaft 5 and the film-collecting roller during residual film recycling, preventing deformation of the first and second cutter discs 12 and 13. This arrangement also facilitates blade maintenance and replacement, reducing the failure rate and maintenance difficulty.

[0043] According to requirements, the leftmost first blade 14 and second blade 15 are both fixedly installed on the right side of the first cutter head 12, and the rightmost first blade 14 and second blade 15 are both fixedly installed on the left side of the first cutter head 12. The first blade 14 and second blade 15 at other positions are fixedly installed on the left and right sides of the first cutter head 12 at their respective positions. The third blade 16 and fourth blade 17 can be set corresponding to the first blade 14, or they can be located between the first blade 14 and the second blade 15. In this embodiment, the first blade 14, second blade 15, third blade 16 and fourth blade 17 have the same structure. The number of projections of all the first blade 14, second blade 15, third blade 16 and fourth blade 17 on the right vertical plane is 8, and the number of corresponding floating plates is 8. The fact that the first blade 14, second blade 15, third blade 16 and fourth blade 17 have the same structure also facilitates the replacement of the blades. The first blade 14, second blade 15, third blade 16 and fourth blade 17 are all arc-shaped, and in the counterclockwise direction, the front end of the first blade 14 away from the central axis 5 has a blade tip.

[0044] Example 4: As an optimization of the above examples, as shown in the appendix. Figure 2 , 5 As shown in Figures 6, 8, and 9, the floating plate includes a first inclined section 27 and a second inclined section 28 connected in sequence. The first inclined section 27 is rotatably mounted together with the first rotating rod 22 and the second rotating rod 23 at corresponding positions. In the clockwise direction, the distance between the front side of the second inclined section 28 and the central axis 5 is greater than the distance between the rear side of the second inclined section 28 and the central axis 5. Connecting arms are fixedly mounted on the left and right sides of the second inclined section 28, and connecting shafts are fixedly mounted on the lower side of the connecting arms. Guide wheels 11 are rotatably mounted on the outside of the connecting shaft at corresponding positions.

[0045] Depending on the requirements, the connecting shaft can be made of existing known technology, such as a connecting bolt. The end of the connecting bolt passes through the guide wheel 11 and is screwed together with the connecting arm. The distance between the front side of the first inclined section 27 and the central shaft 5 is greater than the distance between the rear side of the first inclined section 27 and the central shaft 5. The front side of the second inclined section 28 can be bent towards the central shaft 5 to form an arc-shaped transition section. Support parts matching the first inclined section 27 and the second inclined section 28 are fixed on the outer side of the first cutter head 12 and the outer side of the second cutter head 13. During use, the first inclined section 27 contacts the ground before the second inclined section 28. The distance between the front side of the second inclined section 28 and the central shaft 5 is greater than the distance between the rear side of the second inclined section 28 and the central shaft 5, that is, the inclination degree of the second inclined section 28 is less than the inclination degree of the first inclined section 27. This can prevent the second inclined section 28 from pressing against the ground and lifting the frame 1, which can reduce the floating degree of the frame 1 and reduce the floating height when the film taking roller rotates, making the residual film recycling operation more stable.

[0046] Example 5: As an optimization of the above examples, as shown in the appendix. Figure 6 , 10 As shown in Figure 12, a U-shaped first clamping plate 18 with an outward opening is fixed to the left or right end of the first cutter head 12 corresponding to the position of the first blade 14, and the first blade 14 is fixedly installed in the first clamping plate 18. A U-shaped second clamping plate 19 with an outward opening is fixed to the left or right end of the first cutter head 12 corresponding to the position of the second blade 15, and the second blade 15 is fixedly installed in the second clamping plate 19. A U-shaped third clamping plate 20 with an outward opening is fixed to the left end of the second cutter head 13 corresponding to the position of the third blade 16, and the third blade 16 is fixedly installed in the third clamping plate 20. A U-shaped fourth clamping plate 21 with an outward opening is fixed to the left or right end of the second cutter head 13 corresponding to the position of the fourth blade 17, and the fourth blade 17 is fixedly installed in the fourth clamping plate 21.

[0047] According to requirements, the leftmost first clamping plate 18 and second clamping plate 19 are both fixedly installed on the right side of the first cutter head 12, and the rightmost first clamping plate 18 and second clamping plate 19 are both fixedly installed on the left side of the first cutter head 12. The first blade 14 and second blade 15 in other positions are fixedly installed on the left and right sides of the first cutter head 12 respectively. During use, by setting the U-shaped first clamping plate 18, second clamping plate 19, third clamping plate 20 and fourth clamping plate 21, the first blade 14, second blade 15, third blade 16 and fourth blade 17 can be supported, improving the connection strength with the first cutter head 12 and second cutter head 13, avoiding the separation of the blades from the cutter head during use, reducing the failure rate of the film taking assembly, and thus reducing maintenance costs.

[0048] Example 6: As an optimization of the above examples, as shown in the appendix Figure 3 , 5As shown in Figures 6, 9 to 12, the film-taking roller also includes a first rotating rod 22 and a second rotating rod 23. A first connecting ear 24 protruding outwards is fixed to the outer side of the first cutter disc 12 between each pair of adjacent first blades 14 and second blades 15. A first connecting hole penetrating to the left and right is provided on the left side of the first connecting ear 24. The outer left part of the first rotating rod 22 is fixedly installed in the first connecting hole of the leftmost first connecting ear 24, and the right end of the first rotating rod 22 is fixedly installed in the first connecting hole of the rightmost first connecting ear 24. A second connecting ear 25 protruding outwards is fixed to the outer side of the second cutter disc 13 corresponding to the positions between two adjacent first connecting ears 24. A second connecting hole penetrating to the left side of the second connecting ear 25 is provided. The outer left part of the second rotating rod 23 is fixedly installed in the second connecting hole of the leftmost second connecting ear 25, and the right end of the second rotating rod 23 is fixedly installed in the second connecting hole of the rightmost second connecting ear 25. The floating plate is rotatably mounted together with the corresponding first rotating rod 22 and second rotating rod 23.

[0049] According to the requirements, a matching arc-shaped first groove is provided on the outer side of the second cutter disc 13 corresponding to the position of each first rotating rod 22, and a matching arc-shaped second groove is provided on the outer side of the first cutter disc 12 corresponding to the position of each second rotating rod 23. All the first rotating rods 22 are rotatably installed together with four floating plates, and all the second rotating rods 23 are rotatably installed together with the other four floating plates. Fixing bolts can be installed on both the left and right ends of the first rotating rods 22 and the left and right ends of the second rotating rods 23, which facilitates the disassembly and assembly of the first rotating rods 22 and the second rotating rods 23, and also facilitates the disassembly and assembly of the floating plates and the film taking roller.

[0050] Example 7: As an optimization of the above examples, as shown in the appendix. Figure 3 , 5 As shown in Figures 6, 9 to 12, the leftmost first cutter head 12 has several connecting pipes 26 evenly distributed at intervals on its left end. The right end of each connecting pipe 26 passes through the second cutter head 13 and is fixedly installed on the right end of the rightmost first cutter head 12.

[0051] During use, this setup allows the first cutter disc 12 and the second cutter disc 13 to be fixedly installed together, improving the stability of the film-taking roller. As needed, the left and leftmost first cutter disc 12 of the central shaft 5, as well as the right and rightmost first cutter disc 12 of the central shaft 5, are fixedly installed together by flanges, which facilitates the disassembly and assembly of the film-taking roller.

[0052] Example 8: As an optimization of the above examples, as shown in the appendix Figure 2 , 5As shown in Figure 13, a first adjusting plate 29 is fixedly installed on the lower left side of the mounting bracket 4 and fitted onto the outer side of the left end of the central shaft 5. The left side of the first adjusting plate 29 is provided with several sets of left adjusting holes 79 spaced along the circumference. Each set of left adjusting holes 79 includes at least two left connecting holes 31 that pass through from left to right. The left side of the left guide rail 6 is provided with left connecting screw holes that correspond one-to-one with one of the sets of left connecting holes 31. Each left connecting screw hole is screwed with a left connecting bolt whose left end is located in the corresponding position of the left connecting hole. A second adjusting plate 30 with the same structure as the first adjusting plate 29 and symmetrically distributed is fixedly installed on the lower right side of the mounting bracket 4. The right side of the right guide rail 7 is fixedly installed on the left side of the second adjusting plate 30.

[0053] According to the requirements, the first adjusting plate 29 and the second adjusting plate 30 are both integrally set with the mounting frame 4. The left side of the first adjusting plate 29 has three sets of left adjusting holes evenly distributed along the circumference. Each set of left adjusting holes includes four left connecting holes 31 evenly distributed along the circumference and passing through the left and right sides. The left side of the left guide rail 6 may also be provided with left connecting screw holes that correspond one-to-one with several sets of left connecting holes 31. In this embodiment, the number of left connecting screw holes is 30. The left side of the left guide rail 6 and the right side of the right guide rail 7 are both circumferentially distributed with several observation holes that communicate with the guide groove 8, which facilitates the observation of the operation of the guide wheel 11 and also facilitates the lubrication and disassembly of the guide wheel 11.

[0054] During use, by setting the left connecting hole 31, the left guide rail 6 and the right guide rail 7 are rotated at a certain angle and then fixed together with a set of left adjustment holes 79 and the mounting bracket 4 by the left connecting bolt. This allows adjustment of the position of the guide groove 8 separation point 9 and the film taking point 10. After the frame 1 is installed together with the tractor suspension, when the tractor pulls the frame 1 forward for residual film recycling, the tractor's drive shaft 47 drives the central shaft 5 to rotate through the existing known transmission method. The central shaft 5 rotates counterclockwise, and the blade of the lowest blade inserts into the soil to pick up the residual film in the soil layer. As the guide wheel 11 rotates with the central shaft 5, it moves along the guide groove 8 from the film taking point 10 to the separation point 9. The blade gradually retracts into the corresponding film removal hole. When the roller moves to the separation point 9, the blade is completely retracted. Inside the demolding hole, the inner wall of the demolding hole can scrape off the residual film attached to the blade. The scraped residual film slides down the floating plate to the rear. When the tractor speed is high, the scraped residual film can also be thrown by the floating plate into the residual film bundling assembly for centralized recycling. As the guide wheel 11 continues to move along the guide groove 8 from the separation point 9 to the film taking point 10 with the central shaft 5, the end of the film taking knife gradually extends out from the corresponding demolding hole. When the guide wheel 11 moves to the film taking point 10, the blade of the film taking knife is fully extended out of the demolding hole. At this time, the blade of the film taking knife inserts into the residual film in the soil. As the central shaft 5 continues to rotate, the film taking assembly and the floating plate can continuously pick up and separate the residual film in the soil. The installation position of the left connecting bolt can be adjusted so that the lower part of the frame 1 can still achieve the recycling of residual film during the up and down floating process.

[0055] Example 9: As an optimization of the above examples, as shown in the appendix Figure 2 , 7 As shown in Figures 8 and 13, the left side of the frame 1 corresponding to the position of the first adjusting plate 29 is provided with an arc-shaped left limiting groove 32 with an upward opening. The right side of the frame 1 is provided with a right limiting groove 33 that has the same structure as the left limiting groove 32 and is symmetrically distributed. A dust cover covering the upper outer side of the film taking roller is fixedly installed on the upper side of the middle part of the frame 1. A left support ring 34 with its lower outer side in contact with the lower inner wall of the left limiting groove 32 is fixedly installed on the left outer side of the central shaft 5. A right support ring 35 with the same structure as the left support ring 34 and is symmetrically distributed is fixedly installed on the right outer side of the central shaft 5.

[0056] Depending on the requirements, the left support ring 34 and the right support ring 35 can be existing, known bearing seats. The lower left side of the dust cover is flush with the upper side of the left limiting groove 32, and the lower right side of the dust cover is flush with the upper side of the right limiting groove 33. During use, the left limiting groove 32 and the right limiting groove 33 can limit the left support ring 34 and the right support ring 35, preventing the central shaft 5 from swinging too much during the forward movement of the frame 1 and causing damage to the film-retrieving knife. This also reduces the impact of uneven ground on the mounting frame 4 during residual film recycling operations, avoids deformation of the central shaft 5, and reduces the failure rate and maintenance costs.

[0057] Example 10: As an optimization of the above embodiments, as shown in the appendix Figures 1 to 8 As shown in Figure 13, the straw crushing assembly includes a crushing shaft 36, crushing blades 37, a mounting shell 38, and an arc-shaped baffle 39. A downward-facing mounting shell 38 is fixed to the front of the frame 1. The crushing shaft 36 is rotatably mounted on the lower inner side of the mounting shell 38. Several crushing blades 37 for crushing straw stubble are spaced apart on the outer side of the crushing shaft 36. A first conveying auger 2 is mounted on the upper inner side of the mounting shell 38 corresponding to the position behind the crushing shaft 36. The first conveying auger 2 has a first discharge port 40 at both its left and right ends, and a first feed port 41 at its front. An arc-shaped baffle 39, located behind the crushing shaft 36 and opening forward, is fixedly installed on the lower front side of the first conveying auger 2 at the first feed inlet 41. A transmission box 42 is fixedly installed on the inner upper part of the mounting shell 38. The transmission box 42 is a pyramid shape that is narrow at the front and wide at the back. The inner rear part of the transmission box 42 is fixedly installed together with the inner rear part of the first conveying auger 2. The conveying direction of the first conveying auger 2 to the left of the transmission box 42 is opposite to the conveying direction of the first conveying auger 2 to the right of the transmission box 42. A transmission hole 43 is provided on the upper side of the mounting shell 38, which communicates with the upper rear part of the transmission box 42. The drive assembly includes a support base 44, a first transmission housing 45, and a second transmission housing 46. The support base 44 is fixedly mounted on the upper front side of the mounting housing 38. The first transmission housing 45 is fixedly mounted on the upper side of the support base 44. A drive shaft 47 is fixedly mounted on the front end of the input shaft of the first transmission housing 45. A mounting base 48 is fixedly mounted on the upper right side of the frame 1 corresponding to the position of the first transmission housing 45. A first connecting shaft 50 is rotatably mounted on the mounting base 48. Its left end is fixedly mounted to the first front output shaft 49 of the first transmission housing 45. The right end of the first connecting shaft 50 is drivenly mounted to the right end of the crushing shaft 36, corresponding to the first transmission housing 45. A second transmission box 46 is fixedly installed on the upper rear side of the mounting housing 38 at the rear position. The second front output shaft 51 of the first transmission box 45 is driven and installed together with the front end of the input shaft of the second transmission box 46. The first rear output shaft 52 on the right side of the second transmission box 46 is driven and installed together with the auger shaft of the first conveying auger 2 passing through the transmission box 42. A second connecting shaft 53 is provided on the upper middle side of the frame 1 and is rotatably installed in the connecting cylinder on the left. The right end of the second connecting shaft 53 is driven and installed together with the left end of the second rear output shaft 54 ​​of the second transmission box 46. The left end of the second connecting shaft 53 is driven and installed together with the left end of the central shaft 5.

[0058] According to the requirements, the front of the transmission box 42 smoothly transitions to the front side of the arc-shaped baffle 39. The first transmission box 45 and the second transmission box 46 are both existing known technologies. The front end of the drive shaft 47 is driven and installed together with the output shaft of the tractor. The first conveying auger 2, corresponding to the position of the first discharge port 40, has discharge boxes with lower openings fixed on both sides, which facilitates the concentration of impurities on the left and right sides of the frame 1. The first front output shaft 49 and the first connecting shaft 50 can be integrally formed. The right end of the first connecting shaft 50 is driven and installed together with the right end of the crushing shaft 36 by belt drive. The first rear output shaft 52 on the right side of the second transmission box 46 is driven and installed together with the auger shaft passing through the first conveying auger 2 in the transmission box 42 by belt drive. The right end of the second connecting shaft 53 is driven and installed together with the left end of the second rear output shaft 54 ​​of the second transmission box 46 by universal joint drive. The left end of the second connecting shaft 53 is driven and installed together with the left end of the central shaft 5 by existing known reducer drive.

[0059] During operation, with this setup, the tractor drags the frame 1 forward. The tractor's output shaft is connected to the front end of the drive shaft 47. The drive shaft 47 drives the first front output shaft 49 to rotate the crushing shaft 36 via the first connecting shaft 50. The crushing shaft 36 drives the crushing blades 37 to rotate. After the crushing blades 37 rotate, they crush the straw and throw it into the first conveying auger 2 through the first feed inlet 41. The auger shaft of the first conveying auger 2 rotates under the action of the tractor's output shaft, drive shaft 47, first transmission box 45, second front output shaft 51, second transmission box 46, and first rear output shaft 52. The conveying direction of the first conveying auger 2 on the left side of the transmission box 42 is opposite to that on the right side of the transmission box 42. That is, the spiral direction of the auger blades on the outside of the auger shaft on the left side of the transmission box 42 is opposite to that on the outside of the auger blades on the right side of the transmission box 42. After the auger shaft of the first conveying auger 2 rotates, the straw in the first conveying auger 2 is conveyed to the left and right sides of the frame 1. The first conveying auger 2 has several ventilation holes running through it at intervals to facilitate the conveying of straw. By setting up the transmission box 42, it is easy to separate the straw shredded by the crushing blade 37 to the left and right sides of the first conveying auger 2, and it is also easy to fix the auger shaft of the first conveying auger 2. The inner left and right sides of the first conveying auger 2 are fixedly installed with bearing seats fitted on the outer side of the auger shaft of the first conveying auger 2. This facilitates the setting of the second discharge port 77 and avoids the straw being affected during the discharge process. At the same time, the transmission box 42 is set on the right side of the first conveying auger 2, which makes the structure more compact and facilitates the transmission installation of the first conveying auger 2 and the first rear output shaft 52 together. The upper middle part of the frame 1 has a second connecting shaft 53 rotatably installed in the connecting cylinder on the left. In this way, when the mounting frame 4 swings up and down, the second connecting shaft 53 can still maintain the transmission installation with the central shaft 5. That is, when the mounting frame 4 swings up and down, the central shaft 5 can still rotate continuously, which can continuously carry out residual film recycling operations on undulating ground.

[0060] Example 11: As an optimization of the above embodiments, as shown in the appendix. Figures 2 to 8As shown in Figure 13, the residual film bundling assembly includes a lower left box plate 55, a lower right box plate 56, an upper left box plate 57, an upper right box plate 58, a first drive roller 61, a lower conveyor belt 59, and an upper conveyor belt 60. The lower left box plate 55 is fixedly installed on the rear left side of the frame 1, and the lower right box plate 56 is fixedly installed on the rear right side of the frame 1. The left part of the first drive roller 61 is rotatably installed on the lower part of the lower left box plate 55, and the right part of the first drive roller 61 is rotatably installed on the front part of the lower right box plate 56. A first driven roller 62 is rotatably installed between the rear part of the lower left box plate 55 and the lower part of the lower right box plate 56, corresponding to the position behind the first drive roller 61. Roller 61 and the first driven roller 62 are mounted together via a lower conveyor belt 59. As the lower conveyor belt 59 moves with the first driving roller 61, it transports the residual film that falls off when the end of the film-taking knife gradually retracts into the corresponding film-removing hole to the upper rear side of the lower conveyor belt 59. A first connecting rod 63 located below the lower conveyor belt 59 is fixedly installed between the rear of the lower left box plate 55 and the rear of the lower right box plate 56, corresponding to the position between the first driving roller 61 and the first driven roller 62. A second connecting rod 64 is fixedly installed between the front of the lower left box plate 55 and the front of the lower right box plate 56, corresponding to the position above the first driving roller 61. The lower left box plate 55 and the lower right box plate 56, located behind the second connecting rod 64, are provided with rearward-opening arc-shaped rotating grooves. The lower rear left box plate 55 and the lower rear right box plate 56 are both provided with lower engaging surfaces 65 that are inclined upwards relative to their rear ends. The upper end of the lower engaging surface 65 smoothly transitions to the lower part of the corresponding rotating groove. The lower left box plate 57 and the lower right box plate 58 both have upper engaging surfaces 66 that match the lower engaging surfaces 65. Rotating plates 67 matching the rotating grooves are fixed to the upper front of the upper left box plate 57 and the upper front of the upper right box plate 58. A second active roller 68 is rotatably mounted between the upper parts of the upper left box plate 57 and the upper parts of the upper right box plate 58. A left support lug 70, fixed to the outer left end of the second connecting rod 64, is fitted onto the outer left side of the second active roller 68. A left support lug 70, fixed to the outer right end of the second connecting rod 64, is fitted onto the outer right side of the second active roller 68. The right support lug 71, which is installed together, has a second driven roller 69 rotatably mounted between the rear of the upper left box plate 57 and the rear of the upper right box plate 58, corresponding to the position above the first driven roller 62. The second driving roller 68 and the second driven roller 69 are installed together via the upper conveyor belt 60. A first tension roller 72 is installed between the upper left box plate 57 and the upper right box plate 58, corresponding to the position between the second driving roller 68 and the second driven roller 69. The outer side of the upper part of the first tension roller 72 abuts against the inner side of the upper conveyor belt 60. Opening and closing cylinders 73, which can make the upper fastening surface 66 and the lower fastening surface 65 contact or separate, are installed between the lower left box plate 55 and the upper left box plate 57, and between the lower right box plate 56 and the upper right box plate 58. A third connecting shaft 74 is rotatably mounted in the connecting cylinder on the right side of the middle upper part of the frame 1. The left end of the third connecting shaft 74 is connected to the right end of the third rear output shaft of the second transmission box 46.The right end of the third connecting shaft 74 is driven and mounted together with the right end of the first driving roller 61, and the right end of the first driving roller 61 is driven and mounted together with the right end of the second driving roller 68.

[0061] According to requirements, the lower left box plate 55 and the lower right box plate 56 have the same structure and are symmetrical. The upper left box plate 57 and the upper right box plate 58 have the same structure and are symmetrical. A third connecting rod is fixedly installed between the upper part of the upper left box plate 57 and the upper part of the upper right box plate 58, which are located above the second driving roller 68. A fourth connecting rod is fixedly installed between the lower part of the upper left box plate 57 and the lower part of the upper right box plate 58, which are located above the second driven roller 69. An adjusting rod located above the upper conveyor belt 60 is fixedly installed between the upper left box plate 57 and the upper right box plate 58, which are located between the third connecting rod and the first tensioning roller 72. A fan-shaped adjusting hole 79, coaxial with the adjusting rod and extending through the left and right sides, is provided on the left side of both the upper left box plate 57 and the upper right box plate 58, which are located at the position of the first tensioning roller 72. The right side of the first tensioning roller 72 is located in the adjusting hole 79 on the right. The left side of the tension roller 72 is located in the adjustment hole 79 on the left. The left and right ends of the first tension roller 72 are fixedly installed with connecting plates. The left and right sides of the front part of the connecting plate are provided with hinge holes that pass through to the left and right. The left and right ends of the adjustment rod are fitted into the corresponding hinge holes. The front part of the connecting plate is provided with a set screw whose end abuts against the outside of the adjustment rod. This can fix the first tension roller 72 after the adjustment of its position in the adjustment hole 79. Alternatively, existing tension seats, such as roller adjustment seats, can be installed on the sides of the upper left box plate 57 and upper right box plate 58 above the first tension roller 72. This can adjust the tension of the upper conveyor belt 60. The right end of the third connecting shaft 74 is connected to the right end of the first drive roller 61 by chain drive. The right end of the first drive roller 61 is connected to the right end of the second drive roller 68 by chain drive.

[0062] A third connecting shaft 74 is rotatably mounted inside a connecting cylinder on the right side of the upper middle part of the frame 1. The connecting cylinder on the right side serves as a hinged connection between the frame 1 and the mounting frame 4, and also allows the right end of the third rear output shaft to drive the first drive roller 61 and the second drive roller 68 to rotate via the third connecting shaft 74 during the up-and-down swing of the mounting frame 4. This ensures the continuous rotation of the upper conveyor belt 60 and the lower conveyor belt 59. The right end of the first drive roller 61 is driven and mounted together with the right end of the second drive roller 68. The right end of the first drive roller 61 and the right end of the second drive roller 68 rotate in the same direction. Residual film falls off or is thrown onto the upper surface of the lower conveyor belt 59. The film is conveyed backward. When the residual film is conveyed to the upper part of the rear of the lower conveyor belt 59, the lower surface of the upper conveyor belt 60 moves upward. In this way, the upper conveyor belt 60 and the lower conveyor belt 59 can have a winding effect on the residual film. The residual film is continuously transported backward. The residual film bundling assembly can wind the residual film together to form a residual film roll. After a certain period of operation, the tractor pulls the frame 1 to the end of the field, and the opening and closing cylinder 73 works. After the piston rod of the opening and closing cylinder 73 is output, the upper fastening surface 66 and the lower fastening surface 65 move away from each other. The wound residual film is conveyed to the designated position by the action of the lower conveyor belt 59, which facilitates the subsequent centralized processing of the residual film.

[0063] Example 12: As an optimization of the above embodiments, as shown in the appendix Figure 2 , 5 As shown in Figure 8, a second conveying auger 75 is installed on the lower part of the frame 1 corresponding to the position between the first conveying auger 2 and the central shaft 5. A second discharge port 77 is provided on the left side of the second conveying auger 75, and a second feed port 76 with an opening facing backward is provided at the rear of the second conveying auger 75. A guide plate with its front part inclined downward relative to its rear part is fixedly installed on the inner side of the frame 1 corresponding to the position of the second feed port 76. At least one baffle plate 78 is provided at intervals in the frame 1 corresponding to the position above the guide plate. A hinge shaft is fixedly installed at the front left end and front right end of each baffle plate 78, which is rotatably installed together with the corresponding position of the frame 1. A fan-shaped adjusting hole 79 with the left and right sides of the frame 1 corresponding to the position above the rear of each hinge shaft is provided. An adjusting screw 80 with its end fixedly installed together with the corresponding position of the rear of the baffle plate 78 is provided in each adjusting hole 79. An adjusting nut is screwed to the outside of each adjusting screw 80. The right end of the auger shaft of the second conveying auger 75 is drivenly installed together with the right end of the third connecting shaft 74.

[0064] As required, the lower side of the second feed inlet 76 is flush with the upper front side of the guide plate, and the right end of the auger shaft of the second conveying auger 75 is connected to the right end of the third connecting shaft 74 via chain drive. During use, the soil and impurities attached to the residual film picked up by the film-taking knife fall into the second conveying auger 75 and can be conveyed to the left side of the frame 1 by the second conveying auger 75. This makes the picked-up residual film cleaner and the soil layer in the planting area cleaner, which is conducive to the planting of crops later. By setting the fan-shaped adjusting hole 79 and adjusting screw 80, the tilt angle of the baffle plate 78 can be adjusted according to the position of the film-taking point 10 and the separation point 9, which facilitates the separation and discharge of impurities and soil clods attached to the residual film.

[0065] Example 13: As an optimization of the above embodiments, as shown in the appendix Figures 2 to 8 As shown in Figure 13, swing arms 81 are rotatably mounted on the left and right rear sides of the frame 1. Each swing arm 81 is equipped with a transport wheel 3 at its lower part. A lifting cylinder 82 is installed between the lower rear side of each swing arm 81 and the upper part of the frame 1. A rear support cylinder 84 is rotatably mounted on the lower side of the frame 1 at the position between the front of the swing arm 81 and the rear of the central shaft 5. A front support cylinder 83 located below the first conveying auger 2 is rotatably mounted on the lower front side of the frame 1 at the position between the second conveying auger 75 and the arc-shaped baffle 39.

[0066] During use, the front support cylinder 83 and the rear support cylinder 84 can support the frame 1 and crush the soil on the ground. When the frame 1 is transported on the road, the piston rod of the lifting cylinder 82 can be extended, so that the swing arm 81 swings downward and the transport wheel 3 contacts the ground, raising the front support cylinder 83 and the rear support cylinder 84, which facilitates the rapid transfer of the straw returning to the field and residual film recycling round baler on the road. When the residual film is recycled, the piston rod of the lifting cylinder 82 can be retracted, so that the swing arm 81 swings upward and the transport wheel 3 is raised, and the front support cylinder 83 and the rear support cylinder 84 descend and contact the ground, thus supporting the frame 1 and crushing the soil on the ground.

[0067] The above technical features constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
