Description

Technical Field

[0001] The present application relates to the technical field of agricultural machinery, and in particular to a residual film recycling machine. Background Art

[0002] The mulching planting technology is to cover the ground with plastic film after planting crops to achieve the effects of moisture conservation, temperature increase, drought resistance, water conservation, etc., thereby improving the yield and quality of crops. However, although the widespread use of mulch has brought about increased production and income, it has also led to the residue of mulch that is difficult to degrade, causing problems such as soil compaction and environmental pollution. Therefore, it is necessary to use a residual film recycling machine to recycle the residual film in the field.

[0003] When recycling residual film, the existing residual film recycling machine directly transfers the picked up residual film to the collection frame. This collection method causes the residual film to be in a scattered state in the collection frame. When the residual film in the collection frame accumulates to full load, the residual film recycling machine driver will pour out the residual film. However, in the case of strong winds, both the residual film in the collection frame and the residual film that has been poured from the collection frame to the ground may be blown away by the strong wind and pollute the environment again. In addition, when the existing residual film recycling machine is picking up residual film, it is easy for the forward speed and the film picking speed to not match, resulting in the problem of missing residual film.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0034] The residual film recycling machine provided in the embodiment of the present application comprises a frame 1, a transmission mechanism 2, a picking mechanism 3, a contour wheel 4, a film stripping mechanism 5 and a packaging device 6. Figures 1 to 14 The packaging device 6 includes two winding mechanisms 61, two baffles 62 and a packaging transmission assembly 64.

[0035] The transmission mechanism 2 is arranged on the frame 1, and an input end thereof is used to be connected to a rear end transmission shaft of the traction device.

[0036] The traction device can be connected to the frame 1 of the residual film recycling machine to drive the residual film recycling machine to move, and the tail of the traction device has a rear transmission shaft, which is connected to the input shaft of the transmission mechanism 2 of the residual film recycling machine to transmit power. For example, the traction device can be an agricultural tractor.

[0037] The picking mechanism 3 is connected to the frame 1. When the residual film recycling machine travels in the field, the picking mechanism 3 rotates and picks up the residual film in the soil and transmits it to the film stripping mechanism 5.

[0038] like Figure 1 and Fig.12 As shown, both ends of the profiling wheel 4 are rotatably connected to the frame 1, and the profiling wheel 4 is transmission-connected to the picking mechanism 3 for rolling on the soil surface.

[0039] In the embodiments of the present application, Fig.12 As shown, the chain transmission mode can be used to realize transmission connection between the profiling wheel 4 and the picking mechanism 3. Specifically, a third sprocket 41 is installed at one end of the profiling wheel 4, a fourth sprocket 42 is installed at one end of the film picking roller, and a second chain 43 is wound around the third sprocket 41 and the fourth sprocket 42.

[0040] When the residual film recycling machine is recycling residual film in the field, the contour wheel 4 is close to the soil surface and rolls on the soil surface. The contour wheel 4 drives the picking mechanism 3 to rotate synchronously, so that the picking mechanism 3 matches the traveling speed of the residual film recycling machine, avoiding the situation of missing residual film and improving the effect of picking up residual film.

[0041] Continue to refer to Figure 1 The film stripping mechanism 5 is installed on the frame 1 and is located above the film picking roller, and is transmission-connected to an output end of the transmission mechanism 2, and is configured to separate residual film from impurities.

[0042] like Figure 8 As shown, the picking mechanism 3 picks up the residual film from the soil, and as the picking mechanism 3 rotates, the residual film and impurities such as straw and soil in the residual film remain on the surface of the picking mechanism 3 and are transferred to the film stripping mechanism 5. When the film stripping mechanism 5 is working, the residual film on the surface of the picking mechanism 3 is separated from the impurities, and the residual film is transferred to the packaging space, and the impurities fall from the film stripping mechanism 5 into the field.

[0043] like Figures 9 to 11 As shown, two winding mechanisms 61 are arranged at an acute angle to form a packaging space. The winding mechanism 61 includes a packaging driving shaft 611, a packaging driven shaft 612, a packaging belt 613 and two mounting plates 614.

[0044] The two mounting plates 614 are arranged at intervals. The packing driving shaft 611 is parallel to the packing driven shaft 612. Both ends of the packing driving shaft 611 and both ends of the packing driven shaft 612 are connected and rotated on the two mounting plates 614, and one end of one of the packing driving shafts 611 is transmission-connected to one end of the film stripping mechanism 5. Both ends of the packing transmission assembly 64 are respectively connected to the ends on the same side of the two packing driving shafts 611. When the film stripping mechanism 5 drives one of the packing driving shafts 611 to rotate, the packing transmission assembly 64 enables the two packing driving shafts 611 to be transmission-connected, thereby enabling the two packing driving shafts 611 to rotate synchronously.

[0045] For example, a fifth sprocket is installed at one end of the packing driving shaft 611 located at the bottom, a sixth sprocket is installed at one end of the film stripping mechanism 5, the third chain is wound around the fifth sprocket and the sixth sprocket, and the film stripping mechanism 5 transmits the power of the transmission mechanism 2 to the winding assembly located at the bottom, thereby causing the two packing driving shafts 611 to rotate synchronously. Of course, the fifth sprocket can also be installed at the other end of the upper active roller shaft.

[0046] The packing belt 613 is wound around the packing active shaft 611 and the packing driven shaft 612. Then, the residual film in the packing space will be clamped by the two packing belts 613, and when the two packing belts 613 rotate, they will apply friction forces in opposite directions to the residual film in the packing space, so that the residual film is wound into a cylinder. The residual film newly entering the packing space will continue to be wound on the formed cylinder. As the amount of residual film entering the packing space increases, the diameter of the cylinder gradually increases. When the diameter of the cylinder reaches a preset value, the driver of the residual film recovery machine controls the two winding mechanisms 61 to stop winding the residual film. The residual film taken out from the packing space is a cylinder, which is not easily blown away by strong winds, thus avoiding secondary pollution of the environment by the residual film; moreover, the cylindrical residual film formed by packing is also more convenient to store and handle.

[0047] The preset value may be 1 m, 0.8 m, etc. The operator of the residual film recycling machine can roughly judge by observation whether the diameter of the cylinder wound by the residual film reaches the preset value.

[0048] For example, refer to Fig. 9 The packing belt 613 located at the top applies an outward friction force to the residual film, and the packing belt 613 located at the bottom applies an inward friction force to the residual film.

[0049] Two baffles 62 are respectively arranged on both sides of the two winding mechanisms 61, and are respectively connected to two mounting plates 614 located on the same side. The two baffles 62 and the two winding mechanisms 61 together block the residual film in the packaging space, preventing the residual film from being blown out of the packaging space by strong wind, thereby avoiding secondary pollution of the environment by the residual film.

[0050] The present application embodiment provides a specific structure of the packaging transmission assembly 64, referring to Fig.11 The packing transmission assembly 64 includes a first sprocket 641, a second sprocket 643 and a first chain 642. The first sprocket 641 and the second sprocket 643 are respectively connected to the ends of the two packing driving shafts 611 on the same side. The first chain 642 is respectively wound around the first sprocket 641 and the second sprocket 643.

[0051] Specifically, a first sprocket 641 is installed at one end of the packing driving shaft 611 located at the bottom, and a second sprocket 643 is installed at one end of the packing driving shaft 611 located at the top. The packing driving shaft 611 located at the bottom is connected to one end of the film stripping mechanism 5, and the film stripping mechanism 5 drives the packing driving shaft 611 located at the bottom to rotate, and the first sprocket 641 drives the second sprocket 643 to rotate through the first chain 642, and then the packing driving shaft 611 located at the top connected to the second sprocket 643 rotates synchronously.

[0052] Furthermore, the residual film recycling machine also includes a support member 66 and a telescopic rod 65. Fig.11The two ends of the telescopic rod 65 are respectively hinged to the two mounting plates 614 on the same side of the two winding mechanisms 61. One end of the support member 66 is connected to the end of the packing driving shaft 611 located above, and the other end of the support member 66 is fixedly connected to the frame 1.

[0053] When the residual film recycling driver determines that the cylindrical residual film reaches a preset value, he controls the telescopic rod 65 to extend so that the upper end of the telescopic rod 65 lifts the winding mechanism 61 located above. Since the support member 66 supports the upper packing drive shaft 611, when the telescopic rod 65 extends, the winding mechanism 61 located above rotates around the packing drive shaft 611, and the packing belt 613 located above moves away from the residual film and no longer clamps the residual film. At this time, the cylindrical residual film in the packing space is only subjected to the friction force of the packing belt 613 below, and then the packing belt 613 below discharges the cylindrical residual film from the packing space.

[0054] Exemplarily, when the friction force applied by the two packing belts 613 to the residual film is as follows: Fig. 9 As shown, after the telescopic rod 65 is extended, the residual film wound into a cylindrical shape is discharged from the rear end of the residual film recovery machine.

[0055] The telescopic rod 65 may be a hydraulic cylinder, a pneumatic cylinder, an electric push rod, or the like.

[0056] The mounting plate 614 includes a first connecting section 6141, a second connecting section 6142 and a fastener; one end of the first connecting section 6141 is connected to the end of the packing active shaft 611, and one end of the second connecting section 6142 is connected to the end of the packing driven shaft 612; the first connecting section 6141 partially overlaps with the second connecting section 6142, and the fastener is connected to the overlapping area of ​​the first connecting section 6141 and the second connecting section 6142.

[0057] The overlap between the first connecting section 6141 and the second connecting section 6142 can change the overall length of the mounting plate 614 by adjusting the overlap length, thereby adjusting the distance between the packing active shaft 611 and the packing driven shaft 612, thereby adjusting the tightness of the packing belt 613.

[0058] The first connecting section 6141 is provided with a mounting through hole; the second connecting section 6142 is provided with a long hole corresponding to the mounting through hole, and the long hole extends along the length direction of the second connecting section 6142; the fastener passes through the mounting through hole and the long hole to fix the first connecting section 6141 and the second connecting section 6142.

[0059] When the length of the mounting plate 614 needs to be adjusted, the overlapping length of the first connecting section 6141 and the second connecting section 6142 is changed by changing the position of the long hole where the mounting through hole is located, and using fasteners to fix the first connecting section 6141 and the second connecting section 6142, thereby changing the overall length of the mounting plate 614 and adjusting the tightness of the packing belt 613.

[0060] Since the packing belt 613 needs to compress the residual film in the packing space, it will be easily deformed by the reaction force exerted by the residual film. In order to prevent the packing belt 613 from being greatly deformed and affecting the normal rotation of the winding belt, the winding mechanism 61 in the embodiment of the present application also includes a support component 63, such as Fig.11 The support assembly 63 is located inside the packing belt 613 and is connected to two mounting plates 614 , pressing against the inner side of the packing belt 613 .

[0061] The support assembly 63 located inside the packing belt 613 supports the inner side of the packing belt 613 to prevent the packing belt 613 from being greatly deformed, thereby ensuring that the packing belt 613 can maintain normal rotation when receiving the reaction force applied by the residual film.

[0062] Continue to refer to Fig.11 The support assembly 63 includes two connection seats 631 and a plurality of support rollers 632. The two connection seats 631 are respectively arranged on the inner sides 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 connection seats 631, and the outer circumferential surface of each support roller 632 is pressed against the inner surface of the packing belt 613.

[0063] The plurality of support rollers 632 support the inner side of the packing belt 613 and rotate along with the packing belt 613 . Fig.11 Each support assembly 63 shown in the figure includes four support rollers 632, and the four support rollers 632 jointly support the inner side of the packing belt 613. Of course, the support rollers 632 in each support assembly 63 can also be five, six or other numbers.

[0064] Specifically, the connection seat 631 and the inner side of the mounting plate 614 can be welded, bolted, riveted, etc. A circular hole is formed on the connection seat 631, and the end of the support roller 632 is disposed in the circular hole of the connection seat 631 and can rotate in the circular hole.

[0065] The residual film recovery machine provided in the embodiment of the present application further includes a waste removal mechanism 9, such as Figure 1 The debris removal mechanism 9 includes an auger shaft 91, an auger blade 92 and a debris removal housing 93. Fig.13 .

[0066] The debris removal housing 93 is connected to the frame 1 and opens toward the picking mechanism 3, and is located in front of the picking mechanism 3. Specifically, the debris removal housing 93 can be connected to the frame 1 by welding, bolting, etc. The debris removal housing 93 can receive soil, straw and other debris dropped from the picking mechanism 3.

[0067] The auger shaft 91 is located in front of the picking mechanism 3, and the two ends of the auger shaft 91 are respectively rotatably connected to the debris removal housing 93, and one end of the auger shaft 91 is transmission-connected to an output end of the transmission mechanism 2. Specifically, two bearing seats are provided on the debris removal housing 93, and bearings are installed at both ends of the auger shaft 91. The bearings at both ends of the auger shaft 91 are installed in the bearing seats on the debris removal housing 93, so that the auger shaft 91 can rotate around its own central axis. A third pulley is installed at one end of the auger shaft 91, and a fourth pulley is installed at an output end of the transmission mechanism 2. The second belt is wound around the third pulley and the fourth pulley, so that the power of an output end of the transmission mechanism 2 is transmitted to the auger shaft 91.

[0068] The auger blade 92 is disposed on the outer circumferential surface of the auger shaft 91 and extends along the length direction of the auger shaft 91. When the auger blade 92 rotates, it can push the impurities to move along the length direction of the auger shaft 91. Specifically, the auger blade 92 is connected to the outer circumferential surface of the auger shaft 91 by welding, bonding, etc.

[0069] In the embodiment of the present application, when the debris removal mechanism 9 is working, an output end of the transmission mechanism 2 drives the auger shaft 91 to rotate, and then the auger blades 92 rotate in the debris removal housing 93; soil, straw and other impurities dropped from the picking mechanism 3 enter the interior of the debris removal housing 93 through the opening of the debris removal housing 93, and the continuously rotating auger blades 92 discharge the impurities that have fallen into the debris removal housing 93 from the end of the debris removal housing 93, thereby avoiding the accumulation of impurities at the film picking position, thereby reducing the impurities in the residual film collected by the residual film recovery machine.

[0070] The embodiment of the present application provides a specific structure of the impurity removal housing 93, such as Fig.14 As shown. The debris removal housing 93 includes a first baffle 931, a second baffle 932, a third baffle 933, a baffle cover 934 and an outer plate 935. The outer plate 935 surrounds the outer side of the auger blade 92 and is open toward the picking mechanism 3. The first baffle 931 and the second baffle 932 are arranged at both ends of the outer plate 935 and connected to the frame 1, and a conveying through hole 9321 is opened on the second baffle 932. The baffle cover 934 is connected to the side of the second baffle 932 away from the outer plate 935, and the third baffle 933 is connected to the end of the baffle cover 934 away from the second baffle 932. The two ends of the auger shaft 91 are rotatably connected to the first baffle 931 and the third baffle 933 respectively, and pass through the conveying through hole 9321.

[0071] The first baffle 931 and the third baffle 933 provide installation positions for the auger shaft 91. Specifically, the first baffle 931 and the third baffle 933 are both provided with bearing seats, and bearings are respectively installed at both ends of the auger shaft 91, and the bearings are installed in the bearing seats so that the auger shaft 91 can rotate around its own axis.

[0072] When the debris removal mechanism 9 provided in the embodiment of the present application is working, the auger blades 92 rotate driven by the auger shaft 91, and the auger blades 92 push the soil, straw and other impurities in the debris removal housing 93, so that the impurities move along the length direction of the auger shaft 91 and pass through the conveying through hole 9321, and finally are discharged from between the second baffle 932 and the third baffle 933.

[0073] Reference Fig.14 The peripheral plate 935 in the embodiment of the present application includes a first straight plate 9351, an arc plate 9352, and a second straight plate 9353 connected in sequence. Exemplarily, the first straight plate 9351 and the arc plate 9352, and the second straight plate 9353 and the arc plate 9352 are integrally connected. The first straight plate 9351 and the arc plate 9352, and the second straight plate 9353 and the arc plate 9352 can also be connected by welding, bonding, etc.

[0074] The first straight plate 9351 is located on the side of the auger blade 92 away from the picking mechanism 3, and the side of the first straight plate 9351 away from the arc plate 9352 is connected to the frame 1. The arc plate 9352 surrounds the outer side of the auger blade 92. The side of the second straight plate 9353 away from the arc plate 9352 extends toward the picking mechanism 3.

[0075] When the debris removal mechanism 9 is working, impurities such as soil and straw that fall from the picking mechanism 3 fall onto the second straight plate 9353. When the auger blade 92 rotates, the arc plate 9352 and the first straight plate 9351 block the impurities, causing the impurities to move along the length direction of the auger shaft 91 and finally be discharged from the end of the debris removal housing 93.

[0076] Further, as shown in the figure, the impurity removal housing 93 in the embodiment of the present application also includes a circular tube 936, which is arranged on the side of the second straight plate 9353 away from the arc plate 9352 and extends along the length direction of the arc plate 9352.

[0077] When the impurity removal mechanism 9 provided in the embodiment of the present application is working, the side of the second straight plate 9353 away from the arc plate 9352 is in contact with impurities such as soil and straw for a long time. If the side of the second straight plate 9353 away from the arc plate 9352 is not provided with a circular tube 936, the side of the second straight plate 9353 away from the arc plate 9352 is prone to deformation.

[0078] A circular tube 936 is provided on the side of the second straight plate 9353 away from the arc plate 9352 . The circular tube 936 is in direct contact with impurities, thereby preventing the side of the second straight plate 9353 away from the arc plate 9352 from deforming.

[0079] like Figures 3 to 7 As shown, the embodiment of the present application provides a specific structure of a demolding mechanism 5. The demolding mechanism 5 includes a demolding roller 51 and a plurality of demolding blades 52. Both ends of the demolding roller 51 are rotatably connected to the frame 1, and one end of the demolding roller 51 is transmission-connected to an output end of the transmission mechanism 2. A plurality of demolding blades 52 are arranged in a circular array on the outer circumferential surface of the demolding roller 51, each demolding blade 52 extends along the central axis of the demolding roller 51 and is provided with an outward toothed structure, and each demolding blade 52 is provided with a plurality of filtering holes 521 along its length direction.

[0080] The toothed structure on the film stripping blade 52 can effectively separate the residual film from impurities such as soil and straw, and send the residual film into the packaging space. The multiple filter holes 521 provided on the film stripping blade 52 allow impurities such as soil and straw to pass through during the film stripping process, so that the impurities fall back to the field, thereby reducing the risk of the film stripping roller 51 being blocked.

[0081] like Figure 6 As shown, the tooth structure in the embodiment of the present application includes a plurality of demolding teeth 522. The plurality of demolding teeth 522 are arranged in a linear array along the length direction of the demolding blade 52, and each demolding tooth 522 includes a first tooth surface 5221 and a second tooth surface 5222. Figure 7 The first tooth surface 5221 and the second tooth surface 5222 are connected to form an angle convex to the outside, 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, so that the stripping teeth 522 can separate the residual film from impurities while maintaining the integrity of the residual film, which is convenient for subsequent packaging of the residual film.

[0082] Exemplarily, the first tooth surface 5221 and the second tooth surface 5222 are connected and form an angle of 120°.

[0083] Continue to refer to Figure 7 As shown, the filter hole 521 formed on the film stripping blade 52 is in the shape of an elongated strip, and the length direction of the filter hole 521 is perpendicular to the length direction of the film stripping blade 52 .

[0084] Compared with the round hole, the elongated filter hole 521 has a larger area. During the film stripping process, the elongated filter hole 521 allows dirt, straw and other impurities to pass smoothly, reducing the possibility of the filter hole 521 being blocked.

[0085] Specifically, each long strip-shaped filter hole 521 is located below the first tooth surface 5221 and the second tooth surface 5222 of each demolding tooth 522, thereby achieving a larger length of filter hole 521 in a limited space to ensure that impurities such as soil and straw can be filtered out as much as possible.

[0086] like Figure 5 As shown, the film stripping roller 51 provided in the embodiment of the present application includes a film stripping roller 511 , a fixing plate 512 , a connecting assembly 513 and a film stripping shaft 514 .

[0087] The fixing plate 512 is connected to the outer cylindrical surface of the film stripping roller 511. Specifically, in some embodiments of the present application, the fixing plate 512 is welded to the outer cylindrical surface of the film stripping roller 511. In other embodiments of the present application, the fixing plate 512 and the outer cylindrical surface of the film stripping roller 511 can also be connected by bonding, riveting, etc.

[0088] The fixing plate 512 is detachably connected to the stripping blade 52. Specifically, Figure 5 As shown, the fixed plate 512 is provided with a plurality of first through holes, and as shown in the figure, the demolding blade 52 is provided with a plurality of second through holes; when the demolding blade 52 is connected to the demolding roller 511, the plurality of first through holes on the fixed plate 512 are matched one by one with the plurality of second through holes on the demolding blade 52, bolts are passed through the first through holes and the second through holes, and nuts are tightened, thereby realizing a detachable connection between the demolding blade 52 and the fixed plate 512.

[0089] After long-term use, the toothed structure on the demolding blade 52 wears and affects the demolding effect. The worn demolding blade 52 can be removed from the fixing plate 512 and a new demolding blade 52 can be connected to the fixing plate 512 .

[0090] The connection component 513 is located in the film stripping roller 511, and the connection component 513 is connected to the inner wall of the film stripping roller 511. Specifically, the connection component 513 is fixedly connected to the inner wall of the film stripping roller 511 by welding, bonding, etc.

[0091] One end of the film stripping shaft 514 extends into the film stripping roller 511 and is fixedly connected to the connecting assembly 513, and the other end of the film stripping shaft 514 is rotatably connected to the frame 1, so that the film stripping shaft 514 can drive the film stripping roller 511 to rotate through the connecting assembly 513, thereby realizing the film stripping work. Specifically, bearings are installed on the ends of the two film stripping shafts 514 located outside the film stripping roller 511, and two bearing seats are provided on the frame 1, and the bearings on the film stripping shaft 514 are installed in the bearing seats.

[0092] One of the stripping shafts 514 is in transmission connection with an output end of the transmission mechanism 2. Specifically, a first pulley 54 is installed on one of the stripping shafts 514, a second pulley 55 is installed on an output end of the transmission mechanism 2, and a first belt 56 is wound around the first pulley 54 and the second pulley 55, so that an output end of the transmission mechanism 2 drives the stripping roller 51 to rotate.

[0093] The embodiment of the present application provides a specific structure of the connection component 513, such as Figure 5 As shown, the connecting assembly 513 includes a first spoke plate 5131 and a second spoke plate 5132. The first spoke plate 5131 and the second spoke plate 5132 are arranged at intervals and are both connected to the inner wall of the film stripping roller 511. The end of the film stripping shaft 514 extending into the film stripping roller 511 is connected to the first spoke plate 5131 and the second spoke plate 5132.

[0094] Specifically, the first spoke plate 5131 and the second spoke plate 5132 are both connected to the inner wall of the film stripping roller 511 by welding. The second spoke plate 5132 is close to the end of the film stripping roller 511. When the second spoke plate 5132 is connected to the film stripping roller 511, the second spoke plate 5132 is directly welded to the film stripping roller 511 through the end opening of the film stripping roller 511. The first spoke plate 5131 is located on the side of the second spoke plate 5132 away from the supporting mechanism. The outer circumferential surface of the film stripping roller 511 is provided with a plug welding hole 5133. When the first spoke plate 5131 is connected to the film stripping roller 511, the first spoke plate 5131 is welded to the film stripping roller 511 through the plug welding hole 5133.

[0095] In some other embodiments of the present application, the first spoke plate 5131 and the film stripping roller 511 , as well as the second spoke plate 5132 and the film stripping roller 511 , may be connected by riveting, bonding, or the like.

[0096] exist Figure 5 In the specific structure of the connecting assembly 513 shown, the first spoke plate 5131 and the second spoke plate 5132 fix the end of the demolding shaft 514 that penetrates into the demolding roller 511, so that the demolding shaft 514 can drive the demolding roller 511 to rotate through the first spoke plate 5131 and the second spoke plate 5132.

[0097] In order to prevent the residual film from winding around the stripping shaft 514 and affecting the normal stripping work, continue to refer to Figure 5 As shown, the film stripping mechanism 5 in the embodiment of the present application further includes two anti-winding components 53 , which are respectively connected to the two ends of the film stripping roller 51 and are configured to prevent residual film from winding around the axial end of the film stripping roller 51 .

[0098] like Figure 5As shown, the embodiment of the present application provides a specific structure of the anti-entanglement component 53. The anti-entanglement component 53 includes an anti-entanglement guard plate 531, and a first anti-entanglement ring 532 and a second anti-entanglement ring 533 surrounding the bearing. The anti-entanglement guard plate 531 is connected to the end surface of the film stripping roller 51, the inner wall of the first anti-entanglement ring 532 is connected to the outer edge of the anti-entanglement guard plate 531, and the outer circumferential surface of the first anti-entanglement ring 532 is higher than or flush with the outer edge of the film stripping blade 52. The second anti-entanglement ring 533 is located on the inner side of the first anti-entanglement ring 532, and the second anti-entanglement ring 533 is connected to the side of the frame 1 facing the anti-entanglement guard plate 531.

[0099] The anti-entanglement guard plate 531 and the first anti-entanglement ring 532 work together to prevent residual film from entering the gap between the film stripping roller 511 and the frame 1. The anti-entanglement guard plate 531 can prevent the residual film on the film stripping roller 51 and the film stripping blade 52 from moving in the direction of the frame 1. When a small amount of residual film bypasses the anti-entanglement guard plate 531, the first anti-entanglement ring 532 and the second anti-entanglement ring 533 located on the periphery of the bearing can further block the residual film and prevent the residual film from entering the gap between the film stripping roller 511 and the frame 1, thereby preventing the residual film from winding around the film stripping shaft 514.

[0100] like Figure 1 As shown, the residual film recycling machine provided in the embodiment of the present application further includes a folding mechanism 8 and a running wheel 7, the two ends of the folding mechanism 8 are respectively connected to the bottom of the frame 1 and the running wheel 7, and the folding mechanism 8 is configured to drive the running wheel 7 to fold toward 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 to make the running wheel 7 contact with the road surface, and the contour wheel 4 is in a suspended state at this time to prevent the contour wheel 4 from contacting with the road surface and being damaged.

[0101] The present application embodiment provides a specific structure of the folding mechanism 8, referring to Figure 1 The folding mechanism 8 includes a rocker arm 81 and a hydraulic rod 82.

Both 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 a pin.

[0103] When the residual film recycling machine needs to travel on the road, the rocker arm 81 is pulled to extend the hydraulic rod 82, so that the rocker arm 81 is unfolded and fixed from the frame 1, and the travel wheel 7 is supported on the road surface, so that the contour wheel 4 is in a suspended state. When the residual film recycling machine needs to work in the field, the rocker arm 81 is pulled to shorten the hydraulic rod 82, so that the rocker arm 81 is folded and fixed toward the frame 1, and the contour wheel 4 is in contact with the soil.

[0104] like Figure 1 As shown, the residual film recycling machine provided in the embodiment of the present application further includes a scraper 11.

The scraper 11 can clean the soil off the profiling wheel 4, avoiding the situation where the profiling wheel 4 is difficult to move due to the accumulation of soil on the profiling wheel 4.

[0111] The power transmitted from the input main shaft 21 is transmitted to the first output shaft 222 and the second transmission branch assembly 23 located at the rear through the first commutator 221 .

[0112] The end of the first output shaft 222 away from the first commutator 221 is used for transmission connection with the straw crushing and returning device 10 to transmit power to the straw crushing and returning device 10.

[0114] Exemplarily, the second output shaft 232 and the third output shaft 233 are respectively connected to two output ends of the second commutator 231 through universal joints.

[0115] The power transmitted to the second transmission branch assembly 23 by the second output end of the first commutator 221 is respectively transmitted to the second output shaft 232 and the third output shaft 233 through the second commutator 231.
