[0010] In one possible implementation, the residual film picking mechanism is connected to the first output end of the transmission mechanism via a chain drive; the small residual film recycling machine further includes a chain tensioning mechanism, which is operatively connected to the frame and engages with the chain to adjust the tension of the chain.

The anti-slip plate can increase the interaction force between the ground wheel and the soil, thereby enhancing the rolling performance of the ground wheel. Attached Figure Description

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.

Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two components. 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.

[0026] This application provides a small-scale residual film recycling machine, such as... Figures 1 to 4 As shown, the small residual film recycling machine includes a frame 100, a transmission mechanism 200, a residual film picking mechanism 300, a film stripping mechanism 400, a film collection box 500, and a ground wheel mechanism 600.

[0027] The frame 100 is used to connect to the rear of the traction device. When the small residual film recycling machine is working, the frame 100 is connected to the rear of the traction device, which moves in the field to drive the small residual film recycling machine to collect residual film. For example, the traction device can be an agricultural tractor.

[0028] The transmission mechanism 200 is mounted on the frame 100, and its input end is connected to the tail output shaft of the traction device. The transmission mechanism 200 has a first output end and a second output end. The transmission mechanism 200 can transmit power from the tail output shaft to the residual film picking mechanism 300 and the film removal mechanism 400, which operate under the drive of the traction device.

[0029] The residual film picking mechanism 300 is rotatably connected to the bottom of the frame 100 and is drively connected to the first output end of the transmission mechanism 200. Driven by the first output end of the transmission mechanism 200, the residual film picking mechanism 300 rotates, extending into the soil to pick up residual film. Furthermore, the residual film picking mechanism 300 maintains a constant rotational speed to prevent missed pickups of residual film due to the rolling of the ground wheel 610.

[0030] The film removal mechanism 400 is located above the residual film picking mechanism 300, rotatably connected to the frame 100, and drively connected to the second output end of the transmission mechanism 200. Driven by the second output end of the transmission mechanism 200, the film removal mechanism 400 rotates and separates the residual film wrapped around the residual film picking mechanism 300.

[0031] The film collection box 500 is installed on the frame 100 and is connected to the film removal mechanism 400, and is used to receive the residual film separated by the film removal mechanism 400. During the operation of this small residual film recycling machine, the film collection box 500 is used to hold the residual film.

[0032] The ground wheel mechanism 600 includes a ground wheel 610, two ground wheel axles 620, and multiple anti-slip plates 630. The two ground wheel axles 620 are coaxially mounted on the two end faces of the ground wheel 610 and are rotatably connected to the bottom of the frame 100. The ground wheel 610 limits the operating depth of the residual film picking mechanism 300, preventing it from penetrating too deeply into the soil and being obstructed from rotation. Multiple anti-slip plates 630 are spaced apart along the axial direction of the ground wheel 610 and surround the outer surface of the ground wheel 610. The anti-slip plates 630 increase the force between the ground wheel 610 and the soil, thereby enhancing the rolling performance of the ground wheel 610.

[0033] Reference Figures 1 to 3 In this embodiment of the application, the small residual film recycling machine further includes a suspension mechanism 700, which includes a first suspension plate 710 and a second suspension plate 720 connected to the front end of the frame 100. The first suspension plate 710 is located above the second suspension plate 720, and the first suspension plate 710 and the second suspension plate 720 are respectively provided with a first through hole and a second through hole for connecting to a traction device.

[0034] The tail section of the traction device is hinged to the first suspension plate 710 and the second suspension plate 720 through the first through hole and the second through hole respectively. The traction device can drive the first suspension plate 710 and the second suspension plate 720 to move in the height direction, thereby causing the small residual film recycling machine to move up and down as a whole, and adjusting the working depth of the residual film picking mechanism 300.

[0035] For example, two second suspension plates 720 are connected to the frame 100, and a first suspension plate 710 located above the two second suspension plates 720 is connected to the frame 100, and the first suspension plate 710 is located between the two second suspension plates 720. The axis of the first through hole and the axis of the two second through holes are located in the same vertical plane. The connection between the first suspension plate 710 and the frame 100, and between the second suspension plate 720 and the frame 100, can be welding, riveting, etc.

[0036] Continue to refer to Figures 1 to 3In this embodiment, the film collection box 500 includes a box body 510, a telescopic rod 520, and a film box cover 530. The box body 510 is rotatably connected to the frame 100 and communicates with the film removal mechanism 400 for collecting the residual film separated by the film removal mechanism 400, and the box body 510 has an upward-facing opening. The film box cover 530 is rotatably connected to the box body 510 and is configured to open and cover the opening of the box body 510 under the action of gravity; specifically, the film box cover 530 can be rotatably connected to the box body 510 through multiple hinges. The two ends of the telescopic rod 520 are respectively hinged to the frame 100 and the box body 510. When the telescopic rod 520 extends, it drives the box body 510 to rotate, causing the opening of the box body 510 to rotate backward, and the film box cover 530 rotates and opens the opening of the box body 510.

[0037] For example, the telescopic rod 520 can be an electric push rod, a hydraulic cylinder, etc.

[0038] When the small residual film recycling machine is working, the film removal mechanism 400 removes the residual film wrapped around the residual film picking mechanism 300 and sends it into the box 510 of the film collection box 500. The film box cover 530 covers the opening of the box 510, so that the picked-up residual film is temporarily stored and prevented from being blown away by the airflow. When the small residual film recycling machine finishes its work or the film collection box 500 is full of residual film, the traction device pulls the small residual film recycling machine to the position for dumping residual film. Then, the operator controls the extension rod 520 to extend, and the box 510 rotates under the drive of the extension rod 520. The opening of the box 510 gradually faces the rear of the small residual film recycling machine. Under the action of gravity, the film box cover 530 rotates relative to the box 510 and opens the opening of the box 510. The residual film in the box 510 is dumped out through the opening. After the residual film is poured out, the operator controls the telescopic rod 520 to shorten, and the box 510 rotates under the drive of the telescopic rod 520. The opening of the box 510 gradually faces upward, and the film box cover 530 rotates relative to the box 510 under the action of gravity to cover the opening.

[0039] Furthermore, continue to refer to Figures 1 to 3 The film collection box 500 also includes an inclined bracket 540 and a support shaft 550. Both ends of the support shaft 550 are fixedly connected to the frame 100; the inclined bracket 540 is fixedly connected to the box body 510, one end of the inclined bracket 540 is rotatably connected to the support shaft 550, and one end of the telescopic rod 520 is hinged to the inclined bracket 540.

[0040] The above structure enables a rotatable connection between the housing 510 and the frame 100. Specifically, one end of the telescopic rod 520 drives the inclined bracket 540 to rotate around the support shaft 550, thereby causing the housing 510 to rotate relative to the frame 100 with the center line of the support shaft 550 as the axis of rotation.

[0041] For example, Figures 1 to 3The diagram illustrates the method of fixing the support shaft 550 to the frame 100. Specifically, two sleeves 570 are coaxially arranged and welded to the frame 100. The frame 100 has through holes communicating with the two sleeves 570. The two ends of the support shaft 550 pass through the through holes in the frame 100 and are located inside the two sleeves 570. Two cotter pins pass through the two sleeves 570 and the two ends of the support shaft 550, respectively, fixing the two ends of the support shaft 550 to the two sleeves 570. Of course, in some other examples, the two ends of the support shaft 550 can be directly welded to the frame 100.

[0042] Furthermore, the film collection box 500 also includes a support rod 560, which is connected to the box body 510. When the box body 510 is in a fully closed state, the support rod 560 is pressed against the frame 100, thereby achieving the positioning of the film collection box 500.

[0043] like Figure 2 As shown in this embodiment, the residual film picking mechanism 300 and the first output end of the transmission mechanism 200 are connected by a chain drive; specifically, sprockets are installed at the ends of the residual film picking mechanism 300 and the first output end of the transmission mechanism 200; the chain is wound around the two sprockets. The small residual film recycling machine also includes a chain tensioning mechanism 800, which is operably connected to the frame 100 and engages with the chain to adjust the chain tension.

[0044] The chain tensioning mechanism 800 is used to adjust and maintain the chain tension. Specifically, after the chain is installed, the operator uses the chain tensioning mechanism 800 to initially tension the chain to ensure proper fit between the chain and the sprocket. During transmission, the chain may change due to factors such as wear, elongation, or temperature variations. The operator can then use the chain tensioning mechanism 800 to fine-tune the chain tension based on these changes, maintaining a stable working state for the chain.

[0045] like Figure 2 and Figure 5 As shown in the embodiment of this application, a specific structure of a chain tensioning mechanism 800 is provided. The chain tensioning mechanism 800 includes a slot 810 formed in the frame 100 and extending in the height direction, a fixing rod 820, and a tensioning sprocket 830. The fixing rod 820 passes through the slot 810 and is detachably connected to the frame 100. The tensioning sprocket 830 is rotatably mounted on the fixing rod 820 and engages with the chain.

[0046] When it is necessary to operate the chain tensioning mechanism 800 to adjust the chain tension, disconnect the connection between the fixing rod 820 and the frame 100, and change the position of the fixing rod 820 in the bar hole 810. For example, when it is necessary to tighten the chain, disconnect the connection between the fixing rod 820 and the frame 100, move the fixing rod 820 downward in the bar hole 810, and when the chain reaches the set tension, fix the fixing rod 820 to the frame 100.

[0047] For example, the outer surface of the fixing rod 820 is provided with threads. After the fixing rod 820 passes through the bar hole 810, a nut is tightened onto the fixing rod 820 to fix the chain tensioning mechanism 800 to the frame 100.

[0048] like Figure 3 As shown in this embodiment, the film removal mechanism 400 and the second output end of the transmission mechanism 200 are connected by a belt drive; specifically, pulleys are installed at both ends of the film removal mechanism 400 and the second output end of the transmission mechanism 200, and belts are wound on the two pulleys. The small residual film recycling machine also includes a belt tensioning mechanism 900, which is operatively connected to the frame 100 and contacts the belt to adjust the belt tension.

[0049] The belt tensioning mechanism 900 ensures that the belt has proper tension during operation, preventing belt slippage or slack; furthermore, the belt tensioning mechanism 900 can adjust the wrap angle between the belt and the pulley to improve conveying efficiency.

[0050] like Figure 3 and Figure 6 As shown in the embodiment of this application, a specific structure of a belt tensioning mechanism 900 is provided. The belt tensioning mechanism 900 includes a tensioning shaft 910, a tensioning bracket 920, a tensioning pulley 930, and an adjusting assembly 940. The tensioning shaft 910 is connected to the frame 100 and is orthogonal to the belt. The tensioning bracket 920 is rotatably connected to the tensioning shaft 910. The tensioning pulley 930 is mounted on the tensioning bracket 920 and abuts against the outer surface of the belt. The adjusting assembly 940 is operably connected to the frame 100 and connected to the tensioning bracket 920 to drive the tensioning bracket 920 to rotate around the tensioning shaft 910.

[0051] When it is necessary to adjust the belt tension, the operator operates the adjustment component 940 to make the tension bracket 920 rotate around the tension shaft 910. Depending on the rotation direction of the tension bracket 920, the tension wheel 930 installed on the tension bracket 920 tightens or loosens the belt.

[0052] Furthermore, the adjustment assembly 940 includes a tensioning plate 941 and a threaded adjustment rod 942. The tensioning plate 941 is fixedly connected to the frame 100 and has an adjustment through hole. One end of the threaded adjustment rod 942 is rotatably connected to the tensioning bracket 920, and the other end of the threaded adjustment rod 942 passes through the adjustment through hole and is fixed with a nut.

[0053] When it is necessary to operate the adjustment component 940 to rotate the tension bracket 920, the operator loosens the nut, causing the threaded adjustment rod 942 to move in the adjustment through hole, which in turn drives the tension bracket 920 to rotate. When the belt is adjusted to the set tension, the nut is used to fix the threaded adjustment rod 942 to the tension plate 941.

[0054] like Figures 1 to 4 As shown in this embodiment, the small residual film recycling machine further includes an impurity cleaning mechanism 1100. The impurity cleaning mechanism 1100 is connected to the bottom of the frame 100, located in front of the residual film picking mechanism 300, and one end of the impurity cleaning mechanism 1100 is drivenly connected to the second output end of the transmission mechanism 200. The impurity cleaning mechanism 1100 is used to collect impurities such as straw and soil that fall from the residual film picking mechanism 300, and transport these impurities to the side of the small residual film recycling machine, so as to prevent the impurities falling from the residual film picking mechanism 300 from accumulating in front of the small residual film recycling machine and affecting the residual film recycling work.

[0055] like Figures 1 to 4 As shown in this embodiment, the small residual film recycling machine further includes a protective mechanism 1000, which is connected to the frame 100 and used to protect the internal structure of the frame 100. The protective mechanism 1000 includes a first protective cover 1010, a second protective cover 1020, a third protective cover 1030, and two baffles 1040 connected to the frame 100. The first protective cover 1010 surrounds the outside of the transmission mechanism 200, the second protective cover 1020 surrounds the outside of the film removal mechanism 400, the third protective cover 1030 surrounds the outside of the impurity cleaning mechanism 1100, and the two baffles 1040 are located on both sides of the film removal mechanism 400.
