Description

Technical Field

[0001] This application relates to the field of agricultural machinery technology, and in particular to a residual film recycling machine. Background Technology

[0002] Mulching technology, with its excellent effects in heat preservation, moisture retention, and weed suppression, has significantly increased crop yields, especially in arid and cold regions where it has been widely promoted and applied. However, with the increasing use of mulch film, the amount of residual film in fields is also showing an increasing trend. Therefore, the work of recycling residual film is particularly important.

[0003] However, recycling residual plastic film is no easy task. Because the film is relatively thin and is usually recycled in the autumn, its mechanical properties are at their worst, undoubtedly increasing the difficulty of recycling. Traditional manual collection methods are not only time-consuming and labor-intensive but also relatively inefficient. While using biodegradable film is an environmentally friendly option, its cost is high, and its degradation effect is easily affected by environmental factors, hindering its widespread application. In contrast, residual plastic film recycling machines, with their high efficiency, have gradually become the mainstream method for recycling residual plastic film, providing an effective solution to the problem of residual plastic film in agricultural production.

[0004] Existing residual film recovery machines use spring-loaded teeth to pick up the film, and the movement trajectory of the spring-loaded teeth is controlled by a cam plate and an eccentric rod. During the film picking process, the spring-loaded teeth extend from inside the drum, gradually retracting after picking up the film, and fully retracting into the drum when reaching the film removal position. However, due to the elasticity of the spring-loaded teeth, residual film may be ejected during the film picking process, resulting in a low recovery rate. Furthermore, existing residual film recovery machines are prone to mismatches between the forward speed and the film picking speed, leading to missed collection of residual film. Summary of the Invention

[0005] This application provides a residual film recycling machine to solve the technical problems of low residual film recycling rate and easy missed film collection in existing residual film recycling machines.

[0006] This application provides a residual film recycling machine, comprising: a frame; a transmission mechanism disposed on the frame, the input end of which is connected to the rear drive shaft of a traction device; a picking mechanism, comprising: a picking roller, both ends of which are rotatably connected to the frame, and the roller having multiple slots on its circumferential surface; multiple picking components arranged in a circular array around the central axis of the picking roller, each picking component including a picking toothed shaft and multiple picking teeth spaced apart on the picking toothed shaft; the picking toothed shaft is located inside the picking roller and parallel to the central axis of the picking roller, and both ends of the picking toothed shaft are rotatably connected to the two end faces of the picking roller; a directional disc mounted on the frame and provided with an annular slide rail facing the picking roller; and a directional rod, one end of which is fixedly connected to one end of the picking toothed shaft, and the other end of which... A sliding connection to the annular slide rail is configured to drive the film-collecting tooth shaft to rotate in a second direction from its highest point to gradually extend the film-collecting teeth out of the slot from the film-collecting roller, and to rotate in a first direction from its lowest point to gradually retract the film-collecting teeth from the slot into the film-collecting roller; wherein the first direction and the second direction are opposite directions; a contour wheel, whose two ends are rotatably connected to the frame and drivenly connected to the film-collecting roller, is used to roll on the soil; a film-removing mechanism, installed on the frame and located above the film-collecting roller, is drivenly connected to one output end of the transmission mechanism, and is used to separate residual film from impurities; and a packaging mechanism, installed on the frame and drivenly connected to the film-removing mechanism, is configured to package the residual film separated by the film-removing mechanism.

[0007] The technical solutions provided in this application embodiment have at least the following technical effects:

[0008] This application provides a residual film recycling machine. When recycling residual film in a field, the conforming wheel contacts and rotates with the soil, driving the film-collecting roller to rotate. This matches the rotation speed of the film-collecting roller with the machine's travel speed, preventing missed film collection and improving the recycling rate. Furthermore, the transmission mechanism transmits power from the traction device to the film-removing mechanism, which drives the baling mechanism. The picking mechanism picks up the residual film from the soil, separating impurities from the film and transferring it to the baling mechanism, which then packages the film. When the picking mechanism collects residual film from the soil, the film-collecting roller rotates, driving multiple picking components to rotate around its central axis. One end of the directional rod slides in the annular slide rail of the directional disc, while the other end drives the film-collecting toothed shaft to rotate in a first direction from its lowest point and in a second direction from its highest point; the first and second directions are opposite. As the film-collecting toothed shaft rotates in the second direction from its highest point, the film-collecting teeth gradually extend from the slots on the film-collecting roller. When the shaft reaches its lowest point, the extension length of the teeth is at its maximum, and they pick up the residual film from the field. As the shaft rotates in the second direction from its lowest point, the teeth gradually retract from the slots on the roller. When the shaft reaches its highest point, the teeth are fully retracted into the roller, leaving the residual film on its surface. This facilitates the separation of the residual film and impurities from the film by the film-removing mechanism. The film-collecting teeth in the picking mechanism can gradually extend and retract from the roller as the shaft rotates. They are not easily deformed when encountering hard objects and will not eject the residual film during the picking process, thus improving the residual film recovery rate.

Detailed Implementation

[0034] Existing residual film recovery machines use spring-loaded teeth to pick up the film, and the movement trajectory of the spring-loaded teeth is controlled by a cam plate and an eccentric rod. During the film picking process, the spring-loaded teeth extend from inside the drum, gradually retracting after picking up the film, and fully retracting into the drum when reaching the film removal position. However, due to the elasticity of the spring-loaded teeth, residual film may be ejected during the film picking process, resulting in a low recovery rate. Furthermore, existing residual film recovery machines are prone to mismatches between the forward speed and the film picking speed, leading to missed collection of residual film.

[0035] For the reasons mentioned above, this application provides a residual film recycling machine, which please refer to in conjunction with the above. Figures 1 to 23 This residual film recycling machine can match the travel speed with the film picking speed, thereby improving the residual film recycling rate.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] In the description of the embodiments of this application, it should be noted that the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the embodiments of this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0038] This application provides an embodiment of a residual film recycling machine, which includes a frame 1, a transmission mechanism 2, a picking mechanism 3, a contour wheel 4, a film removal mechanism 5, and a packaging mechanism 6. Figure 1 and Figure 2 As shown.

[0039] The transmission mechanism 2 is mounted on the frame 1, and its input end is used to connect to the rear drive shaft of the traction equipment.

[0040] The traction device can be connected to the frame 1 of the residual film recycling machine to drive the machine. The traction device has a rear drive shaft at its tail, which is connected to the input shaft of the transmission mechanism 2 of the residual film recycling machine to transmit power to it. For example, the traction device can be a tractor.

[0041] Reference Figure 3 and Figure 4 The picking mechanism 3 in this embodiment includes a film picking roller 31, a picking assembly 32, a directional disc 33, and a directional rod 34.

[0042] Both ends of the film-collecting roller 31 are rotatably connected to the frame 1, and multiple slots 3111 are opened on the circumferential surface of the film-collecting roller 31. Specifically, bearings are installed at both ends of the film-collecting roller 31, and bearing seats are provided on the frame 1, with the bearings at both ends of the film-collecting roller 31 installed in the bearing seats.

[0043] Multiple pickup components 32 are arranged in a circular array around the central axis of the film-picking roller 31. When the film-picking roller 31 rotates, the multiple pickup components 32 revolve around the central axis of the film-picking roller 31 to pick up residual plastic film in the soil.

[0044] For example, in Figure 1 In the pickup mechanism 3 shown, six pickup components 32 are evenly arrayed around the central axis of the film pickup roller 31. Of course, the number of pickup components 32 can also be eight, ten, or other numbers.

[0045] Specifically, in this embodiment, the pickup component 32 includes a pickup toothed shaft 321 and a plurality of pickup teeth 322, the plurality of pickup teeth 322 being spaced apart on the pickup toothed shaft 321, such as Figure 7 As shown. The film-collecting tooth shaft 321 is located inside the film-collecting roller 31 and is parallel to the central axis of the film-collecting roller 31. The two ends of the film-collecting tooth shaft 321 are rotatably connected to the two end faces of the film-collecting roller 31, respectively. The film-collecting teeth 322 are used to extend into the soil and pick up the residual film in the soil. Each film-collecting tooth 322 corresponds to a slot 3111 on the film-collecting roller 31, and can extend out of the film-collecting roller 31 through the slot 3111 or retract into the film-collecting roller 31 through the slot 3111 when the film-collecting tooth shaft 321 rotates.

[0046] The orientation disc 33 is mounted on the frame 1 and is provided with an annular slide rail 335 facing the film picking roller 31. The annular slide rail 335 is used to limit the sliding trajectory of the orientation rod 34, so that one end of the orientation rod 34 makes a circular motion within the annular slide rail 335.

[0047] One end of the directional rod 34 is fixedly connected to one end of the film-collecting toothed shaft 321, and the other end of the directional rod 34 is slidably connected to the annular slide rail 335. It is configured to drive the film-collecting toothed shaft 321 to rotate in a second direction from its highest position to gradually extend the film-collecting teeth 322 out of the slot 3111 from the film-collecting roller 31, and to rotate in a first direction from its lowest position to gradually retract the film-collecting teeth 322 from the slot 3111 into the film-collecting roller 31. The first direction and the second direction are opposite directions.

[0048] The annular slide rail 335 is used to guide the end of the directional rod 34 to perform circumferential motion, so that while the film picking roller 31 rotates and drives multiple picking components 32 to revolve, the directional rod 34 can drive the corresponding film picking tooth shaft 321 to rotate in the first direction and the second direction around its own axis, so that the film picking tooth 322 extends out of the slot 3111 from the film picking roller 31 or retracts into the film picking roller 31.

[0049] The following combination Figure 10 Provide a detailed explanation of the film collection process. Figure 10 In the shown perspective, the first direction is clockwise, and the second direction is counterclockwise. When the film-collecting tooth shaft 321 rotates in the second direction from its highest point, the film-collecting teeth 322 gradually extend from the slots 3111 on the roller. Before the film-collecting tooth shaft 321 reaches its lowest point, the film-collecting teeth 322 begin to penetrate the soil and pick up the film. When the film-collecting tooth shaft 321 reaches its lowest point, the front end of the film-collecting teeth 322 reaches point Q, and the penetration depth of the film-collecting teeth 322 reaches its maximum. As the roller continues to rotate, the film-collecting teeth 322 move upwards from point Q, picking up the residual film in the soil. When the film-collecting tooth shaft 321 rotates in the first direction from its lowest point, the film-collecting teeth 322 gradually retract from the slots 3111 on the roller. When the film-collecting tooth shaft 321 reaches its highest point, the film-collecting teeth 322 are completely retracted into the roller, and the residual film is carried by the film-collecting teeth 322 to point P and remains on the surface of the roller, facilitating subsequent collection of the residual film. The film picking teeth 322 in the residual film picking mechanism 3 can rotate with the film picking tooth shaft 321, gradually extending and retracting from the roller. When it touches a hard object, it is not easily deformed and will not eject the residual film during the picking process, thus improving the residual film recovery rate.

[0050] Therefore, the film-picking teeth 322 in the residual film recycling machine provided in this application embodiment can gradually extend and retract from the film-picking roller 31 as the film-picking tooth shaft 321 rotates, thereby picking up the residual film in the soil. The film-picking teeth 322 are not easily deformed when they touch hard objects, and will not pop the residual film out during the picking process, thus improving the recycling rate of residual film.

[0051] like Figure 1 and Figure 20 As shown, the two ends of the contour wheel 4 are rotatably connected to the frame 1, and the contour wheel 4 is drivenly connected to the film picking roller 31 for rolling on the soil surface.

[0052] In the embodiments of this application, such as Figure 1 As shown, the contouring wheel 4 and the film picking roller 31 can be connected by a chain drive. Specifically, a first sprocket 41 is installed at one end of the contouring wheel 4, and a second sprocket 42 is installed at one end of the film picking roller 31. The first chain 43 is wound around the first sprocket 41 and the second sprocket 42.

[0053] When the residual film recycling machine is working in the field to collect residual film, the contour wheel 4 is in close contact with the soil surface and rolls on the soil surface. The contour wheel 4 drives the film picking roller 31 to rotate synchronously, so that the film picking roller 31 matches the traveling speed of the residual film recycling machine, avoiding the situation of missing residual film and improving the residual film recycling rate.

[0054] Continue to refer to Figure 1 The film removal mechanism 5 is installed on the frame 1 and located above the film picking roller 31, and is connected to one output end of the transmission mechanism 2 for separating residual film from impurities.

[0055] like Figure 16 As shown, the picking mechanism 3 picks up the residual film from the soil, and as the picking roller 31 rotates, the residual film and impurities such as straw and soil in the film remain on the surface of the picking roller 31 and are transferred to the film removal mechanism 5. When the film removal mechanism 5 is working, it separates the residual film from the impurities on the surface of the picking roller 31 and transfers the residual film to the packing mechanism 6, while the impurities fall from the film removal mechanism 5 into the field.

[0056] The packaging mechanism 6 is installed on the frame 1 and connected to the film removal mechanism 5, and is configured to package the residual film separated by the film removal mechanism 5. The residual film packaged by the packaging mechanism 6 is easier to collect, transfer and process.

[0057] like Figure 4 and Figure 5 As shown in the figure, the embodiment of this application provides a specific structure of the film picking roller 31. The film picking roller 31 includes a protective cylinder 311, a film picking shaft 313, and two side plates 312.

[0058] Two side plates 312 are respectively connected to both ends of the protective cylinder 311, and both ends of the film-collecting toothed shaft 321 are rotatably connected to the two side plates 312. The two side plates 312 support both ends of the film-collecting toothed shaft 321, allowing the multiple film-collecting toothed shafts 321 to revolve around the central axis of the film-collecting roller 31 while also rotating around their own axes. Specifically, each side plate 312 is equipped with multiple bearing seats arranged in an array around the central axis of the protective cylinder 311, and bearings are installed at both ends of the film-collecting toothed shaft 321, with the bearings at both ends of the film-collecting toothed shaft 321 housed within the bearing seats.

[0059] The protective sleeve 311 has multiple slots 3111 for the film-collecting teeth 322 to extend and retract. When the film-collecting tooth shaft 321 rotates and the film-collecting teeth 322 gradually retract through the slots 3111 into the protective sleeve 311, the protective sleeve 311 can separate the residual film from the film-collecting teeth 322, leaving the residual film on the outer surface of the protective sleeve 311, so that the film-removing mechanism 5 above the film-collecting roller 31 can separate the residual film from the impurities in the residual film.

[0060] The film-collecting shaft 313 extends along the central axis of the film-collecting roller 31 and is connected to the film-collecting roller 31. Both ends of the film-collecting shaft 313 are rotatably connected to the frame 1. Specifically, bearings are installed at both ends of the film-collecting shaft 313. Two bearing seats are provided on the frame 1, and the two bearings on the film-collecting shaft 313 are respectively installed in the two bearing seats.

[0061] One end of the film-collecting shaft 313 is connected to one end of the contouring wheel 4. Specifically, a first sprocket 41 is installed at one end of the contouring wheel 4, and a second sprocket 42 is installed on the film-collecting shaft 313. A first chain 43 is wound around the first sprocket 41 and the second sprocket 42.

[0062] Furthermore, in some embodiments of this application, reference is made to... Figure 5 As shown, the protective sleeve 311 includes a first protective plate 3112 and a second protective plate 3113. The first protective plate 3112 and the second protective plate 3113 are alternately connected in the circumferential direction, and each has a plurality of slots 3111 arranged in an array parallel to the central axis of the protective sleeve 311. A film-picking tooth shaft 321 is correspondingly provided on the inner side of each first protective plate 3112 and each second protective plate 3113.

[0063] Multiple slots 3111 on the first protective plate 3112 and multiple slots 3111 on the second protective plate 3113 are staggered. Each slot corresponds to a multiple film-picking tooth 322 mounted on a film-picking tooth shaft 321. Correspondingly, the multiple film-picking teeth 322 on the film-picking tooth shaft 321 inside the first protective plate 3112 and the multiple film-picking teeth 322 on the film-picking tooth shaft 321 inside the second protective plate 3113 are staggered, allowing the film-picking teeth 322 on adjacent film-picking tooth shafts 321 to pick up different positions of the residual film, making it easier to pick up the residual film.

[0064] For example, Figure 6The diagram illustrates the specific structure connecting the first guard plate 3112 and the second guard plate 3113. The film-collecting roller 31 also includes a square tube 3114 and a square plate 3115. Both ends of the square tube 3114 are connected to the two side plates 312, respectively. The square plate 3115 is connected to the square tube 3114 and extends in a direction parallel to the central axis of the film-collecting roller 31. Both the first guard plate 3112 and the second guard plate 3113 are connected to the square plate 3115. Bolts pass through the first guard plate 3112, the square plate 3115, and the second guard plate 3113, and nuts are tightened onto the bolts.

[0065] When the picking mechanism 3 picks up residual film, the picking teeth extend into the soil and lift up the residual film. The soil will exert a reaction force on the picking teeth 322. To prevent the picking tooth shaft 321 from bending or to reduce the degree of bending of the picking tooth shaft 321, so as to ensure the normal operation of the picking tooth shaft 321 and the picking teeth 322 provided on the picking tooth shaft 321, the picking roller 31 in this embodiment of the application also includes a picking support plate 10113314 and a plurality of picking support sleeves 315, such as Figure 1 As shown. The film picking support plate 10113314 is located inside the protective cylinder 311 and is connected to the inner wall of the protective cylinder 311. Multiple film picking support sleeves 315 are respectively fitted into multiple film picking tooth shafts 321 inside the film picking roller 31, and all multiple film picking support sleeves 315 are connected to the film picking support plate 10113314.

[0066] Multiple film-collecting support sleeves 315 support multiple film-collecting tooth shafts 321 respectively, so that each film-collecting tooth shaft 321 is supported at both ends and in the middle, thereby enhancing the rigidity of the film-collecting tooth shaft 321 and making it less prone to large deformation due to the reaction force of the soil, ensuring that the film-collecting assembly can work normally when subjected to large reaction forces.

[0067] This application provides a specific structure for the orientation disk 33, such as... Figure 9 As shown. The directional disc 33 includes an inner circular plate 331, an outer circular plate 332, and an outer plate 333. The inner circular plate 331 and the outer circular plate 332 are concentrically arranged on the end face of the outer plate 333 facing the film-collecting roller 31, forming an annular slide rail 335. The end of the directional rod 34 away from the film-collecting toothed shaft 321 is located between the inner circular plate 331 and the outer circular plate 332.

[0068] The outer wall of the inner circular plate 331, the inner wall of the outer circular plate 332, and the end face of the outer plate 333 facing the film-collecting roller 31 together define an annular slide rail 335. The end of the directional rod 34 away from the film-collecting tooth shaft 321 is surrounded by the annular slide rail 335. Thus, when the film-collecting roller 31 rotates, the end of the directional rod 34 away from the film-collecting tooth shaft 321 can make a circular motion within the annular slide rail 335, thereby driving the film-collecting tooth shaft 321 to move around its own axis in a first direction and in a second direction.

[0069] Furthermore, the outer plate 333 has a through hole 3331, which is located on the inner side of the inner circular plate 331. One end of the film picking roller 31 passes through the through hole 3331 and is rotatably connected to the frame 1.

[0070] To facilitate the installation of the end of the directional rod 34 away from the film-collecting tooth shaft 321 into the annular slide rail 335, the outer circular plate 332 in this embodiment has a slot, and the directional disk 33 also includes an arc-shaped plate 334, which is detachably connected to the outer plate 333 and located at the slot. The inner wall of the arc-shaped plate 334 and the inner wall of the outer circular plate 332 are located on the same cylindrical surface. For example, as shown... Figure 1 As shown, the arc plate 334 is detachably connected to the outer plate 333 by bolts and nuts.

[0071] When installing the end of the directional rod 34 away from the film-collecting tooth shaft 321 into the annular slide rail 335, the arc plate 334 is removed from the outer plate 333, the end of the directional rod 34 is inserted into the annular slide rail 335 through the slot on the outer circular plate 332, and then the arc plate 334 is connected to the outer plate 333.

[0072] This application provides a specific structure for the directional rod 34, such as... Figure 8 As shown. The directional rod 34 includes a connecting rod 341, a fixed shaft 342, and a roller 343. One end of the connecting rod 341 is connected to the end of the film-collecting toothed shaft 321. The fixed shaft 342 is parallel to the central axis of the film-collecting roller 31, and one end of the fixed shaft 342 is connected to the connecting rod 341, while the other end of the fixed shaft 342 is fitted with the roller 343. The roller 343 is mounted within an annular slide rail 335. When the pickup mechanism 3 performs residual film pickup, the roller 343 moves in a circular motion within the annular slide rail 335, thereby driving the film-collecting toothed shaft 321 to rotate around its own axis in a first direction and a second direction.

[0073] Continue to refer to Figure 8 , Figure 8 The diagram illustrates a specific connection method between the film-collecting toothed shaft 321 and the connecting rod 341. The connecting rod 341 has a mounting hole 3411 and a slot 3412 communicating with the mounting hole 3411. The directional rod 34 also includes a first fastener 344, which is installed at the end of the connecting rod 341 and passes through the slot 3412, and is configured to narrow the slot 3412. The mounting hole 3411 is fitted onto the end of the film-collecting toothed shaft 321. When the connecting rod 341 is connected to the film-collecting toothed shaft 321, the end of the film-collecting toothed shaft 321 is placed in the mounting hole 3411, and the first fastener 344 is tightened to narrow the slot 3412, thereby clamping the end of the film-collecting toothed shaft 321 within the inner wall of the mounting hole 3411.

[0074] To prevent residual film from entangled in the film-picking shaft 313 of the picking mechanism 3, causing the film-picking roller 31 to stop working and ensuring the continuous and efficient operation of the picking mechanism 3, the picking mechanism 3 in this embodiment also includes an anti-entanglement protective ring 35. (Continuing to refer to...) Figure 1 As shown. The anti-tangling guard ring 35 is installed on the end face of the film picking roller 31 facing the drive wheel and surrounds the film picking shaft 313.

[0075] like Figure 11 As shown in the embodiment of this application, a specific structure of the film stripping mechanism 5 is provided. The film stripping mechanism 5 includes a film stripping roller 51 and a plurality of film stripping blades 52. The two ends of the film stripping roller 51 are rotatably connected to the frame 1, and one end of the film stripping roller 51 is drively connected to an output end of the transmission mechanism 2. The plurality of film stripping blades 52 are arranged in a circular array on the outer circular surface of the film stripping roller 51. Each film stripping blade 52 extends along the central axis of the film stripping roller 51 and is provided with an outward toothed structure. Furthermore, each film stripping blade 52 has a plurality of filter holes 521 along its own length direction.

[0076] The toothed structure on the stripping blade 52 can effectively separate the residual film from impurities such as soil and straw, and send the residual film into the packaging mechanism 6. The multiple filter holes 521 set on the stripping blade 52 allow impurities such as soil and straw to pass through during the stripping process, so that the impurities fall back into the field, thereby reducing the risk of the stripping roller 51 being blocked and improving the stripping efficiency.

[0077] like Figure 14 As shown, the toothed structure in this embodiment includes a plurality of stripping teeth 522. The plurality of stripping teeth 522 are arranged in a linear array along the length direction of the stripping blade 52, and each stripping tooth 522 includes a first tooth surface 5221 and a second tooth surface 5222, as shown in the figure. Figure 15 The first tooth surface 5221 and the second tooth surface 5222 are connected to form an outwardly convex angle, and an obtuse angle is formed between the first tooth surface 5221 and the second tooth surface 5222 to reduce the possibility of the residual film being torn. This allows the stripping tooth 522 to separate the residual film from impurities while maintaining the integrity of the residual film, making it easier to package the residual film in the future.

[0078] For example, the first tooth surface 5221 and the second tooth surface 5222 are connected and form a 120° angle.

[0079] Continue to refer to Figure 15 As shown, the filter holes 521 on the stripping blade 52 are elongated, and the length direction of the filter holes 521 is perpendicular to the length direction of the stripping blade 52.

[0080] Compared to round holes, the elongated filter holes 521 have a larger surface area. During the membrane removal process, the elongated filter holes 521 allow impurities such as soil and straw to pass through smoothly, reducing the possibility of the filter holes 521 becoming clogged.

[0081] Specifically, each elongated filter hole 521 is located below the first tooth surface 5221 and the second tooth surface 5222 of each stripping tooth 522, thereby enabling the setting of a relatively long filter hole 521 within a limited space to ensure that impurities such as soil and straw can be filtered out as much as possible.

[0082] like Figure 13 As shown, the stripping roller 51 provided in this embodiment includes a stripping roller 51 cylinder, a fixing plate 512, a connecting assembly 513, and a stripping shaft 514.

[0083] The fixing plate 512 is connected to the outer circular surface of the stripping roller 51. Specifically, in some embodiments of this application, the fixing plate 512 is welded to the outer circular surface of the stripping roller 51. In other embodiments of this application, the fixing plate 512 and the outer circular surface of the stripping roller 51 can also be connected by bonding, riveting, or other methods.

[0084] The fixing plate 512 and the demolding blade 52 are detachably connected. Specifically, as shown... Figure 1 As shown, the fixing plate 512 has multiple first through holes, such as... Figure 1 As shown, the stripping blade 52 has multiple second through holes. When the stripping blade 52 is connected to the stripping roller 51, the multiple first through holes on the fixing plate 512 are matched one-to-one with the multiple second through holes on the stripping blade 52. Bolts are passed through the first and second through holes and tightened with nuts, thereby achieving a detachable connection between the stripping blade 52 and the fixing plate 512.

[0085] When the stripping blade 52 is used for a long time, the toothed structure on the stripping blade 52 will wear out. The worn stripping blade 52 can be removed from the fixing plate 512 and a new stripping blade 52 can be connected to the fixing plate 512.

[0086] The connecting component 513 is located inside the stripping roller 51 and is connected to the inner wall of the stripping roller 51. Specifically, the connecting component 513 is fixedly connected to the inner wall of the stripping roller 51 by welding, bonding or other connection methods.

[0087] One end of the stripping shaft 514 extends into the stripping roller 51 and is fixedly connected to the connecting assembly 513. The other end of the stripping shaft 514 is rotatably connected to the support mechanism, so that the stripping shaft 514 can drive the stripping roller 51 to rotate through the connecting assembly 513, thereby realizing the stripping operation. Specifically, bearings are installed on the ends of the two stripping shafts 514 located outside the stripping roller 51. Two bearing seats are provided on the frame 1, and the bearings on the stripping shafts 514 are installed in the bearing seats.

[0088] One of the demolding shafts 514 is connected to an output end of the transmission mechanism 2. Specifically, a first belt 56 pulley 54 is mounted on one of the demolding shafts 514, and a second belt pulley 55 is mounted on an output end of the transmission mechanism 2. The first belt 56 is wound around the first belt 56 pulley 54 and the second belt pulley 55, thereby causing an output end of the transmission mechanism 2 to drive the demolding roller 51 to rotate.

[0089] This application provides a specific structure for the connecting component 513, such as... Figure 13 As shown, the connecting assembly 513 includes a first wheel spoke 5131 and a second wheel spoke 5132. The first wheel spoke 5131 and the second wheel spoke 5132 are spaced apart and are both connected to the inner wall of the stripping roller 51. The end of the stripping shaft 514 that extends into the stripping roller 51 is connected to the first wheel spoke 5131 and the second wheel spoke 5132.

[0090] Specifically, both the first spoke 5131 and the second spoke 5132 are connected to the inner wall of the stripping roller 51 by welding. The second spoke 5132 is located near the end of the stripping roller 51. When the second spoke 5132 is connected to the stripping roller 51, it is directly welded to the stripping roller 51 through the end opening of the stripping roller 51. The first spoke 5131 is located on the side of the second spoke 5132 away from the support mechanism. The outer circumference of the stripping roller 51 has a plug weld hole 5133. When the first spoke 5131 is connected to the stripping roller 51, it is welded to the stripping roller 51 through the plug weld hole 5133.

[0091] In some other embodiments of this application, the first wheel spoke 5131 and the stripping roller 51, and the second wheel spoke 5132 and the stripping roller 51, can be connected by riveting, bonding or other means.

[0092] exist Figure 13 In the specific structure of the connecting assembly 513 shown, the first wheel spoke 5131 and the second wheel spoke 5132 fix the end of the stripping shaft 514 that is inserted into the stripping roller 51, so that the stripping shaft 514 can drive the stripping roller 51 to rotate through the first wheel spoke 5131 and the second wheel spoke 5132.

[0093] To prevent residual film from entangled on the demolding shaft 514 and affecting the normal demolding process, continue to refer to... Figure 3 As shown, the demolding mechanism 5 in this embodiment of the application further includes two anti-entanglement components 53. The two anti-entanglement components are respectively connected to both ends of the demolding roller 51 and are configured to prevent residual film from entangled around the shaft end of the demolding roller 51.

[0094] To prevent residual film from entangled with the demolding shaft 514 and to ensure the normal demolding operation of the demolding roller 51, this application embodiment provides a specific structure for the anti-entanglement component 53, such as... Figure 13 As shown. The anti-winding assembly 53 includes an anti-winding guard plate 531, and a first anti-winding ring 532 and a second anti-winding ring 533 surrounding the bearing. The anti-winding guard plate 531 is connected to the end face of the stripping roller 51. The inner wall of the first anti-winding ring 532 is connected to the outer edge of the anti-winding guard plate 531, and the outer circular surface of the first anti-winding ring 532 is higher than or flush with the outer edge of the stripping blade 52. The second anti-winding ring 533 is located inside the first anti-winding ring 532 and is connected to the side of the anti-winding guard plate 531 facing the frame 1.

[0095] The anti-winding guard plate 531 and the first anti-winding ring 532 work together to prevent residual film from entering the gap between the stripping roller 51 and the frame 1. When a small amount of residual film passes around the anti-winding guard plate 531 and the first anti-winding ring 532, the second anti-winding ring 533 can further block the residual film, preventing the residual film from wrapping around the stripping shaft 514.

[0096] like Figure 1 As shown, the residual film recycling machine provided in this embodiment of the application also includes a folding mechanism 8 and a traveling wheel 7. The two ends of the folding mechanism 8 are respectively connected to the bottom of the frame 1 and the traveling wheel 7. The folding mechanism 8 is configured to drive the traveling wheel 7 to fold towards the frame 1 and unfold from the frame 1. When the residual film recycling machine needs to travel on the road, the folding assembly unfolds, so that the traveling wheel 7 contacts the road surface. The contour wheel 4 is in a suspended state at this time to avoid the contour wheel 4 from contacting the road surface and being damaged.

[0097] This application provides a specific structure for the folding mechanism 8, referring to... Figure 1 The folding mechanism 8 includes a rocker arm 81 and a hydraulic rod 82. The two ends of the rocker arm 81 are rotatably connected to the bottom of the frame 1 and the traveling wheels 7, respectively. The two ends of the hydraulic rod 82 are rotatably connected to the middle of the rocker arm 81 and the bottom of the frame 1, respectively.

[0098] Specifically, one end of the rocker arm 81 is rotatably connected to the bottom of the frame 1 using a pin, and the other end of the rocker arm 81 is welded to the shaft of the traveling wheel 7. The two ends of the hydraulic rod 82 are rotatably connected to the middle of the rocker arm 81 and the bottom of the frame 1 using pins, respectively.

[0099] When the residual film recycling machine needs to travel on the road, the rocker arm 81 is moved to extend the hydraulic rod 82, causing the rocker arm 81 to unfold from the frame 1 and be fixed, with the traveling wheels 7 supporting the road surface and the contouring wheels 4 suspended in the air. When the residual film recycling machine needs to work in the field, the rocker arm 81 is moved to shorten the hydraulic rod 82, causing the rocker arm 81 to fold back towards the frame 1 and be fixed, with the contouring wheels 4 in contact with the soil.

[0100] like Figure 9As shown, the residual film recycling machine provided in this application embodiment also includes a scraper 9. The scraper 9 is located behind the traveling wheel 4 in the direction of travel, is connected to the bottom of the frame 1 and extends downward, and the scraper 9 is inclined in the direction of travel of the traveling wheel 4 and close to the surface of the traveling wheel 4.

[0101] When the residual film recycling machine is working in the field, the contour wheel 4 comes into contact with the soil, and soil will stick to the surface of the contour wheel 4. The scraper 9 can clean the soil off the contour wheel 4, avoiding the situation where soil accumulates on the contour wheel 4 and makes it difficult for the contour wheel 4 to move.

[0102] This application provides a specific structure for the packaging mechanism 6, referring to... Figures 17 to 19 The residual film packaging mechanism 6 includes two winding assemblies 61 and two baffles 62. The two winding assemblies 61 are arranged at an acute angle, and the two baffles 62 are disposed on both sides of the two winding assemblies 61, forming a winding space. The two winding assemblies 61 are respectively configured to apply opposing frictional forces to the residual film entering the winding space, so that the residual film entering the winding space is wound into a cylindrical shape.

[0103] For example, in Figure 1 In the residual film packaging mechanism 6 shown, the upper winding assembly 61 applies an outward frictional force to the residual film within the winding space, while the lower winding assembly 61 applies an inward frictional force to the residual film within the winding space. Of course, the frictional forces applied by the two winding assemblies 61 to the residual film within the winding space can also be combined with... Figure 1 The directions shown are opposite.

[0104] In the embodiment of this application, the residual film packaging mechanism 6 applies opposing frictional forces to the residual film conveyed to the winding space by the residual film recycling machine during operation, causing the residual film to be wound into a cylindrical shape. When the diameter of the wound cylindrical residual film reaches a preset value, the two winding components 61 of the residual film packaging mechanism 6 are controlled to stop working, and the packaged residual film is taken out from the winding space.

[0105] The preset values ​​can be 1m, 0.8m, etc. The operator of the residual film recycling machine can roughly judge whether the diameter of the cylinder formed by the residual film reaches the preset value by observation.

[0106] The two winding components 61 and two baffles 62 of the residual film packaging mechanism 6 provided in this application embodiment obstruct the residual film, making it difficult for the residual film in the winding space to be blown out of the residual film packaging mechanism 6 by the wind. Furthermore, the residual film packaging mechanism 6 winds the residual film into a cylindrical shape, making it less likely for the residual film removed from the residual film packaging mechanism 6 to be blown away by the wind. Therefore, the residual film packaging mechanism 6 provided in this application embodiment can package the residual film, preventing it from being blown away in strong winds, avoiding further environmental pollution from the residual film, and allowing for better storage and disposal of the packaged residual film.

[0107] Continue to refer to Figure 19 This application provides a specific structure for a winding assembly 61. The winding assembly 61 includes a drive roller 611, a driven roller 612, a winding belt 613, and two mounting plates 614. The two mounting plates 614 are spaced apart. The drive roller 611 and the driven roller 612 are arranged parallel to each other, and both ends of the drive roller 611 and the two ends of the driven roller 612 are rotatably connected to the two mounting plates 614, respectively. The winding belt 613 is wound around the drive roller 611 and the driven roller 612 and is configured to apply frictional force to the residual film within the winding space.

[0108] Two mounting plates 614 provide mounting positions for the drive roller 611 and the driven roller 612, and the two mounting plates 614 are connected to the frame 1. The two drive rollers 611 are drivenly connected to one output end of the transmission mechanism 2. The rotation of the drive rollers 611 drives the winding belt 613 to rotate, and the driven roller 612 rotates with the winding belt 613. The outer surface of the winding belt 613 can apply frictional force to the residual film in the winding space, and the two winding belts 613 are set at an acute angle to press the residual film in the winding space.

[0109] Because the winding belt 613 needs to compress the residual film within the winding space, it is prone to deformation due to the reaction force exerted by the residual film. To prevent excessive deformation of the winding belt 613 from affecting its normal rotation, the winding assembly 61 also includes a support assembly 63, such as... Figure 19 As shown. Specifically, the support assembly 63 is located inside the winding belt 613 and is connected to two mounting plates 614, abutting against the inner side of the winding belt 613. The support assembly 63 supports the winding belt 613, preventing the winding belt 613 from undergoing large deformation due to the reaction force of the residual film in the winding space.

[0110] Furthermore, the support assembly 63 in this embodiment includes two connecting seats 631 and a plurality of support rollers 632. The two connecting seats 631 are respectively disposed on the inner side of the two mounting plates 614. The plurality of support rollers 632 are arranged in parallel, and the two ends of each support roller 632 are respectively rotatably connected to the two connecting seats 631, and the outer circumferential surface of each support roller 632 abuts against the inner surface of the wound belt 613.

[0111] For example, Figure 1 Each support assembly 63 shown includes four support rollers 632. Of course, the number of support rollers 632 in each support assembly 63 can also be five, six, or other numbers.

[0112] Specifically, the inner side of the connecting seat 631 and the mounting plate 614 can be connected by welding, bolting, riveting, or other methods. The connecting seat 631 has a circular hole, and the end of the support roller 632 is located in the circular hole of the connecting seat 631 and can rotate within the circular hole.

[0113] When the winding belt 613 rotates under the drive of the drive roller 611, the support roller 632 presses against the inner surface of the winding belt 613 and rotates with the winding belt 613. The support roller 632 supports the winding belt 613 and prevents the winding belt 613 from undergoing large deformation.

[0114] like Figure 19 As shown in the figure, this application embodiment provides a specific structure of mounting plate 614. Mounting plate 614 includes a first connecting section 6141, a second connecting section 6142, and a second fastener 6143. The two ends of the driving roller shaft 611 are respectively connected to the two first connecting sections 6141, and the two ends of the driven roller shaft 612 are respectively connected to the two second connecting sections 6142. The first connecting section 6141 has a mounting through hole. The second connecting section 6142 has an elongated hole corresponding to the mounting through hole, and the elongated hole extends along the length direction of the second connecting section 6142. The second fastener 6143 passes through the mounting through hole and the elongated hole to fix the first connecting section 6141 and the second connecting section 6142.

[0115] The mounting plate 614, through the above structure, allows for length adjustment, thereby adjusting the tension of the winding belt 613. Specifically, by changing the position of the elongated hole where the mounting through hole is located, and using the second fastener 6143 to fix the first connecting segment 6141 and the second connecting segment 6142, the overlap length of the first connecting segment 6141 and the second connecting segment 6142 is changed, adjusting the overall length of the mounting plate 614, and thus adjusting the tension of the winding belt 613.

[0116] Reference Figure 19The packaging mechanism 6 in this embodiment further includes a transmission assembly 64, with both ends of the transmission assembly 64 connected to two drive rollers 611 respectively. The transmission assembly 64 connects the two drive rollers 611, so that when one drive roller 611 rotates, the other drive roller 611 also rotates. Therefore, only one drive roller 611 needs to be connected to an output shaft of the transmission mechanism 2.

[0117] This application embodiment provides a specific structure for the transmission assembly 64. The transmission assembly 64 includes a third sprocket 641, a second chain 642, and a fourth sprocket 643-643. The third sprocket 641 and the fourth sprocket 643-643 are respectively connected to one end of the drive roller shaft 611 of the two winding assemblies 61. The second chain 642 is wound around the third sprocket 641 and the fourth sprocket 643-643. Specifically, the third sprocket 641 is installed at one end of the drive roller shaft 611 of the lower winding assembly 61, and the fourth sprocket 643-643 is installed at one end of the drive roller shaft 611 of the upper winding assembly 61.

[0118] For example, a fifth sprocket is mounted on the other end of the drive roller 611 of the lower winding assembly 61, and a sixth sprocket is mounted on one end of the demolding mechanism 5. A third chain is wound around the fifth and sixth sprockets. The demolding mechanism 5 transmits the power of the transmission mechanism 2 to the lower winding assembly 61, thereby causing the two drive rollers 611 to rotate synchronously. Of course, the fifth sprocket can also be mounted on the other end of the drive roller 611 of the upper winding assembly 61.

[0119] like Figures 17 to 19 As shown, the residual film packaging mechanism 6 provided in this application embodiment also includes an opening and closing component 65. The opening and closing component 65 is connected to the upper winding component 61 and the frame 1, and is configured to drive the upper winding component 61 away from the residual film in the winding space.

[0120] When the operator of the residual film recycling machine determines that the diameter of the cylinder formed by the residual film wound in the winding space has reached the preset value, the operator controls the opening and closing component 65 to lift the winding component 61 located above, so that the winding component 61 located above no longer clamps the residual film, making it easier for the residual film to be discharged from the winding space.

[0121] Furthermore, the direction of the frictional force applied to the residual film by the two winding assemblies 61 in this embodiment can be as follows: Figure 17 As shown. When the upper winding assembly 61 is lifted and detached from the residual film, the residual film is only subjected to the frictional force applied by the lower winding assembly 61, and the residual film wound into a cylindrical shape is discharged outward by the lower winding assembly 61.

[0122] Specifically, this application provides a specific structure for the opening and closing assembly 65. The opening and closing assembly 65 includes a telescopic member 651 and a support member 652. One end of the support member 652 is fixedly connected to the frame 1, and the other end of the support member 652 is rotatably connected to the winding assembly 61 located above. The two ends of the telescopic member 651 are respectively hinged to two winding assemblies 61.

[0123] When the upper winding assembly 61 needs to be lifted, the telescopic member 651 extends, and the upper winding assembly 61 rotates about the end of the support member 652, thereby disengaging the upper winding assembly 61 from the residual film in the winding space. When the upper winding assembly 61 needs to be lowered, the telescopic member 651 shortens, and the upper winding assembly 61 rotates about the end of the support member 652, thereby pressing the upper winding assembly 61 against the residual film in the winding space.

[0124] For example, the telescopic component 651 can be a hydraulic cylinder, a pneumatic cylinder, an electric push rod, etc.

[0125] The residual film recycling machine provided in this application embodiment also includes a straw crushing mechanism 10. The straw crushing mechanism 10 is installed on the frame 1 and located in front of the picking mechanism 3, and is used to crush the straw in the field and return it to the field.

[0126] This application provides a specific structure for the rack 1, referring to... Figure 1 and Figure 2 The frame 1 includes a traction bracket 11, a first mounting bracket 12, and a second mounting bracket 13.

[0127] The traction bracket 11 is used to connect to the tail end of the traction device, enabling the traction device to drive the residual film recycling machine. The front end of the first mounting bracket 12 is connected to the traction bracket 11 and is used to install the straw crushing mechanism 10. The front end of the second mounting bracket 13 is connected to the rear end of the first mounting bracket 12 and is used to install the picking mechanism 3, the contour wheel 4, the film removal mechanism 5, the baling mechanism 6, etc. The transmission mechanism 2 is disposed between the first mounting bracket 12 and the second mounting bracket 13, and includes one power input end and multiple output ends. The power input end of the transmission mechanism 2 is used to connect to the rear output shaft of the traction device, and the multiple output ends of the transmission assembly 64 are used to connect to the straw crushing device, the film removal mechanism 5, and the impurity removal mechanism 101.

[0128] For example, the traction device can be an agricultural tractor.

[0129] The specific structure of the traction bracket 11 in this embodiment is as follows: Figure 1As shown. The traction bracket 11 includes a first swing arm 111 and two second swing arms 112. The first swing arm 111 is used to connect to the tail of the traction device. One end of each of the two second swing arms 112 is connected to a different position at the front end of the first mounting bracket 12, and the other end of each of the two second swing arms 112 is connected to and hinged to the first swing arm 111, forming a first rotation axis perpendicular to the ground.

[0130] Specifically, refer to Figure 1 The front ends of the two second swing arms 112 are connected to the first swing arm 111 via the same pin, and the front ends of the two second swing arms 112 rotate around the pin, the central axis of which is the first rotation axis mentioned above. The two second swing arms 112 extend rearward and the distance between them gradually increases, so that the rear ends of the two second swing arms 112 are respectively connected to two positions at the front end of the first mounting bracket 12.

[0131] The two second swing arms 112 and the first mounting bracket 12 form a triangular structure, giving the traction bracket 11 good stability. After the first swing arm 111 is connected to the traction equipment, the two second swing arms 112, the first mounting bracket 12 and the second mounting bracket 13 can rotate around the first rotation axis, which facilitates the traction equipment to drive the frame structure of the residual film recycling machine to turn.

[0132] Continue to refer to Figure 1 This application provides a specific structure for a first mounting bracket 12. The first mounting bracket 12 includes a base 121, a support frame 122, a first telescopic rod 123, and a second telescopic rod 124. The front end of the base 121 is hinged to a traction bracket 11, and the rear end of the base 121 is hinged to a second mounting bracket 13. The support frame 122 is disposed on the top of the base 121. Both ends of the first telescopic rod 123 are respectively hinged to the traction bracket 11 and the support frame 122, and both ends of the second telescopic rod 124 are respectively hinged to the second mounting bracket 13 and the support frame 122.

[0133] The lengths of the first telescopic rod 123 and the second telescopic rod 124 can be adjusted manually. Adjusting the length of the first telescopic rod 123 changes the angle between the first mounting bracket 12 and the traction bracket 11; specifically, decreasing the length of the first telescopic rod 123 decreases the angle between the first mounting bracket 12 and the traction bracket 11, while increasing the length of the first telescopic rod 123 increases the angle between the first mounting bracket 12 and the traction bracket 11. Similarly, adjusting the length of the second telescopic rod 124 changes the angle between the first mounting bracket 12 and the second mounting bracket 13; specifically, decreasing the length of the second telescopic rod 124 decreases the angle between the first mounting bracket 12 and the second mounting bracket 13, while increasing the length of the second telescopic rod 124 increases the angle between the first mounting bracket 12 and the second mounting bracket 13.

[0134] By adjusting the angle between the first mounting bracket 12 and the traction bracket 11, and the angle between the first mounting bracket 12 and the second mounting bracket 13, the height of the straw crushing mechanism 10 installed on the first mounting bracket 12 and the height of the picking mechanism 3 and the contour wheel 4 installed on the second mounting bracket 13 can be adjusted, so that the straw crushing and returning to the field and the residual film recycling have a better effect.

[0135] For example, the first telescopic rod 123 and the second telescopic rod 124 are double-ended fisheye rods with positive and negative threads. Of course, the first telescopic rod 123 and the second telescopic rod 124 can also be other structures capable of length adjustment.

[0136] like Figure 2 As shown, in this embodiment, the transmission mechanism 2 includes an input main shaft 21, a first transmission branch assembly 22, and a second transmission branch assembly 23. One end of the input main shaft 21 is connected to the input end of the first transmission branch assembly 22, and the other end of the input main shaft 21 is used to connect to the rear output shaft of the traction device. The first transmission branch assembly 22 is disposed on the first mounting bracket 12, and one output end of the first transmission branch assembly 22 is used to connect to the straw crushing mechanism 10. The second transmission branch assembly 23 is disposed on the second mounting bracket 13, and the input end of the second transmission branch assembly 23 is connected to the other output end of the first transmission branch assembly 22. The output end of the second transmission branch assembly 23 is used to connect to the demulsification mechanism 5 and the impurity removal mechanism 101.

[0137] For example, the input spindle 21 is connected to the input end of the first transmission branch assembly 22 via a universal joint, and the output end of the first transmission branch assembly 22 is connected to the second transmission branch assembly 23 via a universal joint. Of course, when the rotation axis of the input spindle 21 coincides with the rotation axis of the input end of the first transmission branch assembly 22, the input spindle 21 can be directly connected to the input end of the first transmission branch assembly 22; when the rotation axis of the output end of the first transmission branch assembly 22 coincides with the rotation axis of the input end of the second transmission branch assembly 23, the output end of the first transmission branch assembly 22 can be directly connected to the input end of the second transmission branch assembly 23.

[0138] When the residual film recycling machine is in operation, the front end of the input main shaft 21 is connected to the rear output shaft of the traction device, and the power of the traction device is transmitted to the input main shaft 21. The input main shaft 21 transmits power to the first transmission branch assembly 22, and one output end of the first transmission branch assembly 22 drives the straw crushing mechanism 10 installed on the first mounting bracket 12. The other output end of the first transmission branch assembly 22 transmits power to the second transmission branch assembly 23, and the output end of the second transmission branch assembly 23 drives the film removal mechanism 5 and the impurity removal mechanism 101 installed on the second mounting bracket 13.

[0139] The power of the traction equipment is transmitted through the transmission mechanism 2 as described above, enabling the simultaneous operation of straw crushing and returning to the field and residual film recycling.

[0140] Furthermore, referring to Figure 2 The first transmission branch assembly 22 includes a first commutator 221 and a first output shaft 222. One end of the first output shaft 222 is connected to the first output end of the first commutator 221, and the rotation axis of the first output end of the first commutator 221 is perpendicular to the rotation axis of the input end of the first commutator 221. The second output end of the first commutator 221 is connected to the input end of the second transmission branch assembly 23.

[0141] The power transmitted from the input spindle 21 is transmitted through the first commutator 221 to the first output shaft 222 and the second transmission branch assembly 23 located behind it.

[0142] The end of the first output shaft 222 away from the first commutator 221 is used for transmission connection with the straw crushing device to transmit power to the straw crushing device. Specifically, a pulley or sprocket can be installed at the end of the first output shaft 222 away from the first commutator 221, and a corresponding pulley or sprocket can be installed at the input end of the straw crushing device to transmit power from the first output shaft 222 to the straw crushing device via a belt or chain.

[0143] Furthermore, referring to Figure 2 The second transmission branch assembly 23 includes a second commutator 231, a second output shaft 232, and a third output shaft 233. The input end of the second commutator 231 is connected to the second output end of the first commutator 221. One end of the second output shaft 232 and one end of the third output shaft 233 are respectively connected to the two output ends of the second commutator 231, and the other ends of the second output shaft 232 and the other ends of the third output shaft 233 are respectively connected to the demolding mechanism 5 and the impurity removal mechanism 101.

[0144] For example, the second output shaft 232 and the third output shaft 233 are respectively connected to the two output ends of the second commutator 231 via universal joints. Of course, when the rotation axis of the second output shaft 232 coincides with the rotation axis of one output end of the second commutator 231, the second output shaft 232 and one output end of the second commutator 231 can be directly connected; when the rotation axis of the third output shaft 233 coincides with the rotation axis of the other output end of the second commutator 231, the third output shaft 233 and the other output end of the second commutator 231 can be directly connected.

[0145] The power transmitted from the second output end of the first commutator 221 to the second transmission branch assembly 23 is then transmitted via the second commutator 231 to the second output shaft 232 and the third output shaft 233, respectively. The end of the second output shaft 232 furthest from the second commutator 231 is connected to one power input end of the residual film recycling device, and the end of the third output shaft 233 furthest from the second commutator 231 is connected to the other power input end of the residual film recycling device. Specifically, the ends of the second output shaft 232 furthest from the second commutator 231 and the ends of the third output shaft 233 furthest from the second commutator 231 can be connected to the film removal mechanism 5 and the impurity removal mechanism 101, respectively.

[0146] like Figure 2 As shown, the transmission mechanism 2 also includes two output shaft seats 24. The two output shaft seats 24 are disposed on the second mounting bracket 13, and the second output shaft 232 and the third output shaft 233 are respectively mounted on the two second output shaft seats 232.

[0147] The second output shaft 232 and the third output shaft 233 can rotate within their corresponding output shaft seats 24. The two output shaft seats 24 support the second output shaft 232 and the third output shaft 233 respectively, so as to transmit power to the demolding mechanism 5 and the impurity removal mechanism 101 respectively.

[0148] like Figure 1 As shown, the transmission assembly 64 also includes a spindle seat 25. The spindle seat 25 is disposed on the traction bracket 11, and the input spindle 21 is mounted on the spindle seat 25. The input spindle 21 is rotatable within the spindle seat 25, and the spindle seat 25 supports the input spindle 21 to transmit power to the first transmission branch assembly 22.

[0149] The residual film recycling machine provided in this application embodiment also includes a waste removal mechanism 101, such as... Figure 1 As shown. The waste removal mechanism 101 includes an auger shaft 1011, auger blades 1012, and a housing 1013, as shown in the reference. Figure 21 .

[0150] The outer casing 1013 is connected to the frame 1 and opens towards the picking mechanism 3, and is located in front of the picking mechanism 3. Specifically, the outer casing 1013 can be connected to the frame 1 by welding, bolting, or other methods. The outer casing 1013 can catch soil, straw, and other debris falling from the picking mechanism 3.

[0151] The auger shaft 1011 is located in front of the pickup mechanism 3. Both ends of the auger shaft 1011 are rotatably connected to the housing 1013, and one end of the auger shaft 1011 is drive-connected to an output end of the transmission mechanism 2. Specifically, the housing 1013 is provided with two bearing seats, and bearings are installed at both ends of the auger shaft 1011. The bearings at both ends of the auger shaft 1011 are installed in the bearing seats on the housing 1013, allowing the auger shaft 1011 to rotate around its own central axis. A third pulley is installed at one end of the auger shaft 1011, and a fourth pulley is installed at an output end of the transmission mechanism 2. A second belt is wound around the third and fourth pulleys, so that the power from the output end of the transmission mechanism 2 is transmitted to the auger shaft 1011.

[0152] Screw blades 1012 are disposed on the outer circular surface of screw shaft 1011 and extend along the length direction of screw shaft 1011. When screw blades 1012 rotate, they can push impurities along the length direction of screw shaft 1011. Specifically, screw blades 1012 are connected to the outer circular surface of screw shaft 1011 by welding, bonding or other methods.

[0153] In this embodiment of the application, when the impurity removal mechanism 101 is working, one output end of the transmission mechanism 2 drives the auger shaft 1011 to rotate, and then the auger blades 1012 rotate inside the housing 1013. Soil, straw and other impurities falling from the picking mechanism 3 enter the interior of the housing 1013 through the opening of the housing 1013. The continuously rotating auger blades 1012 discharge the impurities that fall into the housing 1013 from the end of the housing 1013, avoiding the accumulation of impurities at the film picking position, thereby reducing the impurities in the residual film collected by the residual film recycling machine.

[0154] This application provides a specific structure for the outer casing 1013, such as... Figure 22 As shown. The outer casing 1013 includes a first baffle 1013162, a second baffle 1013262, a third baffle 1013362, a cover 10134, and an outer plate 10135. The outer plate 10135 surrounds the outside of the auger blades 1012 and is open towards the picking mechanism 3. The first baffle 1013162 and the second baffle 1013262 are disposed at both ends of the outer plate 10135 and connected to the frame 1, and the second baffle 1013262 has a conveying through hole 101321. The cover 10134 is connected to the side of the second baffle 1013262 away from the outer plate 10135, and the third baffle 1013362 is connected to the end of the cover 10134 away from the second baffle 1013262. The two ends of the auger shaft 1011 are rotatably connected to the first baffle 1013162 and the third baffle 1013362 respectively, and pass through the conveying through hole 101321.

[0155] The first baffle 1013162 and the third baffle 1013362 provide mounting positions for the auger shaft 1011. Specifically, both the first baffle 1013162 and the third baffle 1013362 are provided with bearing seats, and bearings are installed at both ends of the auger shaft 1011. The bearings are installed in the bearing seats, so that the auger shaft 1011 can rotate around its own axis.

[0156] When the impurity removal mechanism 101 provided in this application embodiment is working, the auger blades 1012 rotate under the drive of the auger shaft 1011. The auger blades 1012 push the soil, straw and other impurities in the outer shell 1013, so that the impurities move along the length direction of the auger shaft 1011 and pass through the conveying through hole 101321, and finally are discharged from between the second baffle 1013262 and the third baffle 1013362.

[0157] Reference Figure 22 In this embodiment, the outer plate 10135 includes a first straight plate 101351, an arc plate 101352, and a second straight plate 101353 connected in sequence. Exemplarily, the first straight plate 101351 and the arc plate 101352, as well as the second straight plate 101353 and the arc plate 101352, are integrally connected. The first straight plate 101351 and the arc plate 101352, as well as the second straight plate 101353 and the arc plate 101352, can also be connected by welding, bonding, or other methods.

[0158] The first straight plate 101351 is located on the side of the auger blade 1012 away from the picking mechanism 3, and the side of the first straight plate 101351 away from the arc plate 101352 is connected to the frame 1. The arc plate 101352 surrounds the outside of the auger blade 1012. The side of the second straight plate 101353 away from the arc plate 101352 extends toward the picking mechanism 3.

[0159] When the debris removal mechanism 101 is working, soil, straw and other impurities that fall from the picking mechanism 3 fall onto the second straight plate 101353. When the auger blade 1012 rotates, the arc plate 101352 and the first straight plate 101351 block the impurities, causing the impurities to move along the length of the auger shaft 1011 and finally be discharged from the end of the outer casing 1013.

[0160] Furthermore, continue to refer to Figure 22 As shown, the outer shell 1013 in this embodiment of the application also includes a circular tube 10136, which is disposed on the side of the second straight plate 101353 away from the arc plate 101352 and extends along the length direction of the arc plate 101352.

[0161] When the debris removal mechanism 101 provided in this application embodiment is working, the side of the second straight plate 101353 away from the arc plate 101352 is in contact with soil, straw and other impurities for a long time. If the round tube 10136 is not provided on the side of the second straight plate 101353 away from the arc plate 101352, the side of the second straight plate 101353 away from the arc plate 101352 is prone to deformation.

[0162] A round tube 10136 is provided on the side of the second straight plate 101353 away from the arc plate 101352. The round tube 10136 is in direct contact with impurities, which can prevent deformation of the side of the second straight plate 101353 away from the arc plate 101352.

[0163] Specifically, the central axis of the arc plate 101352 coincides with the central axis of the auger shaft 1011, thereby making the distance from the edge of the auger blade 1012 to all parts of the arc plate 101352 equal. As a result, when the auger blade 1012 pushes impurities, the arc plate 101352 is subjected to relatively uniform force, avoiding the situation where the auger blade 1012 is subjected to excessive local force and deforms.

[0164] This application provides a specific structure for the auger shaft 1011, referring to... Figure 23 The auger shaft 1011 includes an auger shaft 1011 cylinder, shaft heads 10112, and a support plate 10113. One end of each shaft head 10112 extends into the auger shaft 1011 cylinder and is connected to the inner wall of the cylinder via the support plate 10113. The other end of each shaft head 10112 is located on the outer side of the auger shaft 1011 cylinder and is rotatably connected to the outer casing 1013. The auger blades 1012 are disposed on the outer circumferential surface of the auger shaft 1011 cylinder.

[0165] The auger shaft 1011 adopts the above structure, which reduces the weight of the auger shaft 1011 while ensuring the required diameter size, thus achieving a lightweight design of the auger shaft 1011.
