Description

[0002] Ground film is used to cover the ground of farmland. It has the functions of increasing soil temperature, maintaining soil moisture, maintaining soil structure, preventing pests from attacking crops and diseases caused by certain microorganisms, etc. However, residual ground film pollution is a major problem that needs to be faced and solved for the sustainable development of agriculture. Mechanical recycling is an effective, direct and quick-acting governance technology. In the past, the film rake was mostly used as a picking mechanism to collect residual film. It has a simple structure, but the effective working distance is short, and it needs to stop frequently for manual unloading of the film, which is labor-intensive and time-consuming. The residual film picking rate is also very limited. The existing ground film picking mechanism is mostly used in combination with the picking and stripping device to achieve the purpose of effective picking, and provide preliminary work for the subsequent packaging operation. In the picking process, it is required to minimize the amount of impurities. However, in the actual operation process, the stripping roller is used for stripping. Since there is a gap on the stripping roller, the picking belt passes through the gap to achieve stripping. Therefore, residual impurities may be mixed in the gap, and excessive accumulation will affect the operation of the whole machine.

[0003] Therefore, the applicant proposed a picking and packing mechanism for a residual film recovery machine and a residual film recovery machine composed of the picking and packing mechanism, which has a simple structure, good use effect, can improve the packaging efficiency, and effectively reduce impurities in the film stripping roller and the residual film.

[0018] The utility model also discloses a residual film recycling machine, comprising a frame and walking wheels. The frame is provided with the picking and packaging mechanism used in the residual film recycling machine.

[0019] The working principle of the picking and packing mechanism of the utility model:

[0020] In the picking mechanism, the film-lifting teeth are installed on the surface of the film-lifting belt and are evenly distributed on the film-lifting belt. The interval between the film-lifting teeth is about 200mm. When the film-lifting belt goes around the film loosening and slag removal roller, the tooth tip of the film-lifting teeth is 5-30mm higher than the radius of the film loosening and slag removal roller. When the film-lifting teeth go around the first film-lifting roller, the tooth tip of the film-lifting teeth should be lower than the surface of the first film-lifting roller. When the film-lifting teeth go around the second film-lifting roller, the tooth tip of the film-lifting teeth should be lower than the surface of the second film-lifting roller. The center of the first film-lifting roller is offset from the axis of the first film-lifting roller by 10mm to form an eccentric disc. Each group of adjacent discs is rotated 180 degrees or 120 degrees and fixed on the shaft to form a balanced relationship between the discs. Since the roller disc in the first film stripping roller is an eccentric circle, the non-overlapping and asymmetric nature of its center of circle is used to produce a deflection and tilt of the center of gravity, and a reciprocating motion is formed during rotation to achieve better film stripping. The second film stripping roller is located below the first film stripping roller, and performs a second film stripping on the film that has not been completely stripped by the first film stripping roller. The film loosening and slag removal roller also adopts the design of the first film stripping roller. Since the film removing teeth are higher than the surface of the film loosening and slag removal roller, the film loosening and slag removal roller does not push off the residual film on the film removing teeth when it rotates to form a reciprocating motion. However, due to the shaking caused by the reciprocating motion of the film loosening and slag removal roller, the non-overlapping and asymmetric nature of its center of circle is used to produce a deflection and tilt of the center of gravity, so that the entrained soil and impurities can be easily fallen off.

[0021] In the baling mechanism, the annular wide belt at the front passes over the debris removal auger at the bottom of the frame, and is embedded in the annular groove of the debris removal auger through the guide strips on the lower surface, so that it rotates stably, and the belt will not shift to one side of the debris removal auger; the structure of the debris removal auger consists of two auger sections both turning outward, and the annular wide belt rotates synchronously with the debris removal auger, and the separated small clods of earth, grass roots and other debris enter the auger, and the two auger sections transport the impurities to both sides respectively, and then throw the impurities into the field from the debris removal ports at the bottom or both sides of the frame.

[0022] The multiple rollers at the rear are arranged in an oblique straight line or in a ")" shape, and cooperate with the ring-shaped wide belt at the front to pack the incoming residual film. As the residual film packing increases from small to large, the ring-shaped wide belt will become tighter. This packaging combination structure combining a ring-shaped wide belt with multiple groups of rollers is very suitable for the residual film packaging operation environment, and the structure is simple and practical.

[0023] Compared with the prior art, the picking and packing mechanism of the utility model and the residual film recycling machine constituted by the utility model have the following advantages: in the picking operation, the irregular quadrilateral structure constituted by the film removing roller, the first film stripping roller, the second film stripping roller and the film loosening and slag removal roller can be effectively utilized; the structure is reasonable; the first film stripping roller and the second film stripping roller are utilized for two times of film stripping; the film stripping is clean and efficient; when the film stripping teeth bypass the first film stripping roller, the tooth tip of the film stripping teeth is lower than the surface of the first film stripping roller; when the film stripping teeth bypass the second film stripping roller, the tooth tip of the film stripping teeth is lower than the surface of the second film stripping roller; the film stripping and slag stripping are completed at one time; there is no need to design an accompanying anti-blocking mechanism; the utility model is particularly suitable for residual film recovery operations during the crop harvest season in Xinjiang; the use effect is good; and the impurities in the film stripping roller and the residual film can be effectively reduced, thereby realizing efficient residual film picking and recovery. The utility model performs packaging operations while picking up. During the operation of the packaging circular wide belt, the sticky materials on the belt are not easy to stick to the outer surface of the belt roller, which effectively prevents the belt from sliding to one side and is not easy to be damaged. When applied to the process of baling residual film, the belt can effectively separate the debris entrained in the residual film, and then use the impurity removal auger to effectively discharge the impurities. This packaging combination structure combining the circular wide belt with multiple groups of rollers is very suitable for the residual film packaging operation environment, and the structure is simple and practical. At the same time, the residual film recycling machine provided with the above-mentioned picking and packaging mechanism for the residual film recycling machine is more suitable for the residual film packaging operation environment, with good baling and impurity removal effect, simple structure, and economical and practical.

The axial holes of the eccentric rollers I2-10 and II2-12 are not at their center positions, and the axial width of the eccentric roller II2-12 is greater than the axial width of the eccentric roller I2-10. A plurality of the eccentric rollers I2-10, II2-12 It is fixedly arranged on the roller shaft, and the radial heights of adjacent rollers are staggered. An annular groove I2-11 is formed between the eccentric roller I and the eccentric roller I or between the eccentric roller I and the eccentric roller II. The film stripping belt 2-5 is embedded in the annular groove I2-11 and travels around. The structure of the second film stripping roller 2-3 is that a plurality of annular grooves II2-13 are arranged on a smooth roller at intervals. The axial width of the annular groove II2-13 is set to be the same or different as needed.

[0057] The depth of the annular groove Ⅰ2-11 on the film loosening and slag removal roller 2-7 is relatively shallow, and the film removing teeth 2-6 on the film removing belt 2-5 need to extend out of the annular groove Ⅰ2-11 on the film loosening and slag removal roller 2-7; the depth of the annular groove Ⅰ2-11 on the first film stripping roller 2-4 is relatively deep, and the tooth tip height of the film stripping teeth 2-6 on the film stripping belt is lower than the upper surface of the annular groove Ⅰ2-11 on the first film stripping roller 2-4; the depth of the annular groove Ⅱ2-13 on the second film stripping roller 2-3 is relatively deep, and the tooth tip height of the film stripping teeth on the film stripping belt 2-5 is lower than the upper surface of the annular groove Ⅱ2-13 on the second film stripping roller 2-3.

[0059] The front debris removal auger 3-4 and multiple belt rollers 3-5 are arranged in an upward convex arc shape, and the upper end of the open box 3-1 is open, forming an entrance for residual film; the front debris removal auger 3-4 and multiple belt rollers 3-5 drive the annular wide belt 3-3 to rotate clockwise, and the multiple rollers 3-2 arranged in an oblique straight line at the rear rotate clockwise driven by the chain.

[0060] In the picking mechanism 2, the eccentric roller I2-10 and the eccentric roller II2-12 on the first film stripping roller 2-4 or the film loosening and slag removal roller 2-7 have their axial holes not at their center positions, and are eccentric roller discs, and the offset distance between the center of their axial holes and the center of the roller disc is 8-20 mm. In the present embodiment, the offset distance between the center of their axial holes and the center of the roller disc is preferably 10 mm.

[0061] When the eccentric rollers I2-10 and II2-12 on the first film stripping roller 2-4 or the film loosening and slag removal roller 2-7 are installed and arranged, each group of adjacent roller discs is rotated 180 degrees or 120 degrees and fixed on the roller shaft 2-9, so that a balanced relationship is formed between the roller discs.

[0062] The structures of the plurality of film-lifting belts 2-5 arranged side by side are the same, and the spacing between adjacent film-lifting belts 2-5 is adapted to the spacing between the corresponding adjacent annular grooves I 2-11 or the spacing between adjacent annular grooves II 2-13; the film-lifting teeth 2-6 are in the shape of a prism. The tooth tips of the film-lifting teeth 2-6 are 5-30 mm higher than the upper surface of the film loosening and slag removal plate 2-7.

[0063] In this embodiment, the utility model provides a picking and packaging mechanism, in which the picking mechanism 2 is described, and the film-removing teeth 2-6 are installed on the surface of the film-removing belt 2-5 and are evenly distributed on the film-removing belt 2-5. The film-removing teeth 2-6 are spaced about 200mm apart. When the film-removing belt 2-5 goes around the film loosening and slag removal disk 2-7, the tooth tips of the film-removing teeth 2-6 are 5-30mm higher than the radius surface of the film loosening and slag removal disk 2-7. When the film-removing teeth go around the first film removal disk 2-4, the tooth tips of the film-removing teeth 2-6 are lower than the surface of the first film removal roller.

The film loosening and slag removal roller 2-7 also adopts the design of the first film stripping roller. Because the film teeth are higher than the surface of the film loosening and slag removal roller 2-7, the film loosening and slag removal roller 2-7 does not push the residual film on the film teeth off when it rotates to form a reciprocating motion, but the shaking caused by the reciprocating motion of the film loosening and slag removal roller 2-7 makes it easy for the entrained dirt to fall off. This embodiment has a reasonable structure, is economical and practical, and has a good use effect. The picking structure 2 is used to achieve two film stripping, and the film stripping is clean and efficient. The film stripping and slag removal are completed at one time. There is no need to design an accompanying anti-blocking mechanism. It can effectively reduce the impurity content in the film stripping roller and the residual film, and achieve efficient residual film picking and recovery.

[0064] The residual film that falls off backwards by the picking mechanism 2 enters the packaging mechanism 3 at the rear for packaging. In the packaging mechanism 3, the front wide annular belt 3-3 passes over the debris removal auger 3-4 at the lower part of the frame, and is embedded in the annular groove 3-7 of the debris removal auger 3-4 through the guide bar 3-9 on the lower surface, so as to rotate stably, and the belt will not shift to one side of the debris removal auger 3-4; the structure of the debris removal auger 3-4 is two auger sections that turn outward, and the wide annular belt 3-3 rotates synchronously with the debris removal auger 3-4, and the separated small clods of soil, grass roots and other debris enter the interior of the auger, and the two auger sections respectively transport the impurities to both sides, and then throw the impurities into the field from the debris removal ports at the bottom or both sides of the frame 4.

[0065] The multiple rollers 3-2 arranged in an oblique straight line at the rear cooperate with the annular wide belt 3-3 at the front to pack the incoming residual film. As the residual film packing size increases, the annular wide belt 3-3 will become tighter. This packaging combination structure of the annular wide belt 3-3 and multiple groups of rollers 3-2 is very suitable for the residual film packaging operation environment and has a simple and practical structure.
