Description

Technical Field

[0001] This utility model relates to the field of residual film recycling technology, and more specifically to a residual film recycling machine picking mechanism with a debris removal structure. Background Technology

[0002] With the increasing application and lifespan of agricultural plastic film, the environmental pollution caused by residual film in fields is becoming increasingly prominent. In order to protect arable land, reduce plastic film residue, prevent soil pollution, and promote green agricultural development, it is essential to effectively recycle residual film.

[0003] During the process of picking up residual film, debris such as fallen leaves, soil, and gravel on the film surface can easily become further mixed with the film. The soil and gravel in the debris are relatively heavy, and if they are not effectively separated and removed, it will affect the secondary use of the residual film and cause a heavy load on the tractor. Therefore, a subsequent cleaning mechanism is needed to clean and remove the debris mixed in with the residual film. However, the existing debris removal structure is set up separately from the picking mechanism, which not only makes the structure of the residual film recycling equipment more complicated, but also further leads to higher power consumption of the equipment.

[0004] Therefore, there is an urgent need for a residual film recycling machine with a debris removal structure for picking up the film. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a residual film recycling machine picking mechanism with a debris removal structure, so as to solve the problems in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0007] The residual film recycling machine with a debris removal structure includes a frame connected to an agricultural vehicle. A pickup drive shaft is connected to the upper part of the frame, and a pickup drive wheel with a belt groove is welded onto the pickup drive shaft. A pickup belt for picking up residual film is fitted inside the belt groove of the pickup drive wheel. A pickup driven roller is fitted at the other end of the pickup belt. A pickup driven shaft is installed at the lower part of the frame through a bearing inside the pickup driven roller. A debris removal structure is provided in the upper middle part of the pickup belt to support the pickup belt in a triangular shape and to remove impurities from the surface of the residual film. A debris conveying structure is provided below the debris removal structure and is connected to the drive shaft.

[0008] To further optimize the technical solution, the pickup belt is evenly provided with a number of belt spikes for piercing the residual film. The belt spikes are located at the center line of the belt and the width of the belt spikes is smaller than the width of the belt.

[0009] To further optimize the technical solution, the impurity removal structure includes a pickup intermediate shaft arranged parallel to the pickup drive shaft. A pickup intermediate roller for changing the direction of the pickup belt is mounted on the pickup intermediate shaft via bearings. The pickup intermediate roller is provided with a plurality of nylon discs corresponding to the protrusions on the pickup drive disc for removing impurities from the residual film. The radius of the nylon disc is equal to the sum of the height of the belt spike teeth, the thickness of the pickup belt, and the radius of the pickup intermediate roller.

[0010] To further optimize the technical solution, the nylon disc is provided with several grooves.

[0011] To further optimize the technical solution, the impurity transport structure includes an impurity transport auger horizontally positioned below the intermediate pick-up shaft for receiving impurities and transporting them to one side. The shell of the impurity transport auger is a shell without an upper end face and with an arc-shaped cross-section. A sprocket is provided at the end of the impurity transport auger, and a chain is connected to the sprocket. The other end of the chain is connected to the pick-up drive shaft through the sprocket.

[0012] To further optimize the technical solution, the vertical diameter of the auger is tangent to the nylon disc on the intermediate shaft, and the cross-section of the auger shell is an asymmetrical arc shape; the side end face of the shell near the intermediate shaft extends directly below the axis of the intermediate shaft and its height exceeds the height of the auger axis, and the height of the other side end face is twice the height of the side end face near the intermediate shaft.

[0013] Due to the adoption of the above technical solutions, the technological progress achieved by this utility model is as follows.

[0014] This utility model provides a residual film recycling machine with a debris removal structure for picking up residual film. By incorporating a debris removal structure at the upper part of the picking belt, the debris removal structure is integrated with the picking mechanism, allowing for immediate debris removal after the residual film is picked up. A debris conveying mechanism is located below the debris removal structure, and is connected to the picking drive shaft via a chain, enabling them to share a single drive shaft. This utility model has the advantages of compact structure and small footprint; moreover, the debris removal, picking, and conveying structures share a single power unit, reducing power consumption and equipment costs.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] The residual film recycling machine with a debris removal structure includes a frame for connecting to an agricultural vehicle. The frame has wheels, and the axles of the wheels are connected to the pickup drive shaft via a transmission chain and gears. Figures 1 to 7 As shown, it includes a pickup drive shaft 1, a pickup drive wheel 11, a pickup driven shaft 2, a pickup driven roller 21, a pickup belt 3, belt teeth 4, a waste removal structure 5, and a waste transport structure 6. The waste removal structure 5 includes a pickup intermediate shaft 51, a pickup intermediate roller 52, and a nylon disc 53; the waste transport structure 6 includes a waste transport auger 61, a housing 62, and a chain 63.

[0019] A pickup drive shaft 1 is connected to the upper part of the frame, and the pickup drive shaft 1 is located at the top. A pickup drive wheel 11 is welded to the pickup drive shaft 1 and is arranged coaxially. The pickup drive wheel 11 has a belt groove, and a pickup belt 3 is wound in the belt groove to realize transmission and pickup of residual film.

[0020] The pickup belt 3 is evenly provided with several belt spikes 4 for piercing the residual film. The belt spikes 4 are located at the center line of the belt and the width of the belt spikes 4 is smaller than the width of the belt.

[0021] The other end of the pickup belt 3 is fitted with a pickup driven roller 21, which is located below the pickup drive wheel 11. The pickup driven roller 21 is fitted with a pickup driven shaft 2, which is movably connected to the lower part of the frame through a bearing.

[0022] The upper middle part of the pickup belt 3 is provided with a debris removal structure 5 that supports the pickup belt 3 in an obtuse-angled triangle. The debris removal structure 5 is used to remove impurities on the residual film surface, and the debris removal structure 5 is located at the obtuse angle. Specifically, the debris removal structure 5 includes a pickup intermediate shaft 51 arranged parallel to the pickup drive shaft 1. A pickup intermediate roller 52 is mounted on the pickup intermediate shaft 51 via bearings. The pickup belt 3 rests on the pickup intermediate roller 52 to change the direction of the pickup belt 3. The pickup intermediate roller 52 is provided with a plurality of nylon discs 53 for removing impurities on the residual film. The nylon discs 53 correspond to the protrusions on the pickup drive wheel 11, and the radius of the nylon discs 53 is equal to the sum of the height of the belt spike teeth 4, the thickness of the pickup belt 3, and the radius of the pickup intermediate roller 52.

[0023] The pickup belt 3 rotates clockwise, and the section of the pickup belt 3 from the pickup driven roller 21 to the pickup intermediate roller 52 is in an approximately vertically inclined upward direction.

[0024] The nylon disc 53 has several grooves that form two rings around the center to reduce the weight of the nylon disc.

[0025] Below the impurity discharge structure 5, an impurity conveying structure 6 is provided, and the impurity conveying structure 6 is connected to the drive shaft. Specifically, the impurity conveying structure 6 includes an impurity conveying auger 61 horizontally positioned below the intermediate pickup shaft 51. The impurity conveying auger 61 is mounted on the frame and is used to receive impurities and transport them to one side of the residual film recycling machine's pickup mechanism. The housing 62 of the impurity conveying auger 61 is a housing 62 without an upper end face and with an arc-shaped cross-section. A discharge port is provided on the bottom end face of the housing 62 at the end facing the conveying direction. A sprocket is provided at the end of the impurity conveying auger 61, and a chain 63 is connected to the sprocket. The other end of the chain 63 is connected to the pickup drive shaft 1 through the sprocket to achieve drive transmission.

[0026] The vertical diameter of the auger is tangent to the edge of the nylon disc 53 on the intermediate shaft, and the cross-section of the auger housing 62 is an asymmetrical arc shape. The side end face of the housing 62 near the intermediate shaft extends directly below the axis of the intermediate shaft, and the height of the side end face of the housing 62 near the intermediate shaft exceeds the height of the auger axis. Since the other side end face is in the direction in which impurities fall after running, its height is twice the height of the side end face near the intermediate shaft.

[0027] In practical use, this invention connects the frame to an agricultural vehicle with wheels. The vehicle drags the frame, causing the wheels to rotate. The pickup drive shaft is connected to the shaft of the frame's wheels via a transmission chain and gears. When the vehicle drags the frame, it rotates the pickup drive wheel 11, which in turn drives the pickup driven roller 21 via the pickup belt. When the pickup belt 3 reaches the lower position of the pickup driven roller 21, the belt spikes 4 on the belt 3 insert into the soil, penetrating and lifting the residual film. The film is then transported to the rear by the pickup belt 3, blown by the wind, and enters the baling bin. Impurities fall into the auger of the impurity transport structure 6 under their own gravity, and the auger pushes the impurities to the auger outlet for discharge.
