Description

Chain Type Potato Film Recycling Machine

(1) Technical field

The utility model relates to a chain type potato residual film recycling machine, which belongs to the field of agricultural machinery. the

(2) Background technology

The promotion of plastic film mulching cultivation technology has promoted the increase of crop production and the expansion of crop suitable area, which has brought about the change of agricultural production mode and the leap of agricultural productivity. However, with the expansion of the application range of mulch, its side effects also appear. The residual plastic film in the soil destroys the ecological environment of the farmland, destroys the soil structure, endangers the normal growth and development of crops and causes crop yield reduction. Traditional manual film harvesting is labor-intensive, low productivity and low recovery rate. The implementation of mechanized film collection has become an inevitable trend. At present, the existing plastic film picking devices at home and abroad mostly recover the residual film after the potatoes are harvested. It is easy to be entangled on the recycling device, resulting in leaking film and clogging of residual film, which seriously affects the film collection rate and has a great impact on the performance of the machine tool; the film is not fully lifted, causing the residual film to be missed; the film is easy to drop during the film picking process, which affects the film collection homework effect. Therefore, it is of great significance to design and promote an economical and practical residual film picking device suitable for potato planting mode and agronomic requirements to reduce land pollution and maintain sustainable development of potato production. the

The soil loosening shovel handle is fixedly connected with the frame, and the soil loosening shovel is sleeved on the shovel handle and fixed by bolts; because the fixed frame is hingedly connected with the frame, the depth and angle of the soil penetration can be adjusted according to the needs through the angle adjustment lever , which solves the problem of high difficulty in loosening the film in the field; the film picking work of the residual film recycling machine is mainly completed by rows of film lifting teeth fixed on the connecting rod. The recovery machine should be high and the film can be fully picked up, which solves the problem of missing small pieces of damaged film; the supporting plate is attached to the lower end of the film picking teeth through the tension of the spring, and the lifted residual film passes through the The gap between the film lifting teeth and the supporting plate is conveyed backward and upward, and after reaching the upper side of the film collecting box, it falls into the film collecting box under the action of the film unloading impeller. The whole process protects the lifted residual film well, solving the problem of feeding The film is easy to lose during the filming process; the outer periphery of the connecting rod is equipped with a layer of sealing cover along the root of the filming tooth, which effectively prevents the residual film from slipping into the filming mechanism, and avoids film leakage and residual film blockage during the operation process. The soil loosening shovel loosens the soil in the working field, and the film is picked up by the film lifting teeth and then transported to the rear and upward. The film unloading impeller will drop the residual film on the film lifting teeth into the film collecting box to complete the film collecting operation. Adjust the inclination angle of the fixed frame through the angle adjustment lever to meet different operation requirements. the

The utility model is mainly used for recovering the residual film after harvesting potatoes planted in ridge farming, and is also suitable for recovering residual film after harvesting other flat crops. the

The film collecting box 6 is welded on the frame 1, and is used for containing the residual film recovered. the

The film-raising teeth 8 are fixedly mounted on the connecting rod 4 in rows, and the connecting rod 4 is installed in parallel between two film-moving chains 10. The outer periphery of the connecting rod 4 is provided with a layer of sealing cover 9 along the roots of the film-raising teeth 8, and the sealing cover 9 Wrap up the film chain 10 and the connecting rod 4, the 8 rods of the film teeth are exposed outside the seal cover 9 through the small holes on the seal cover 9, and the whole sprocket chain mechanism is fixedly connected on the fixed frame 7 through the bearing seat combination, according to It is necessary to adjust the angle of the fixing frame 7 through the angle adjusting rod 11 . the

Supporting plate 3 is vertically installed on the lower end of film tooth 8, and is connected with fixed mount 7 by spring 5, and supporting plate 3 is parallel with fixed mount 7, and fits on the lower end of film tooth 8 by the tension of spring 5. the

The film unloading impeller 28 is assembled on the top of the fixed frame 7 through the bearing housing. The film unloading impeller 28 adopts a brush structure, and the width of the unloading film impeller 28 is equal to the width of the connecting rod 4 . The film unloading impeller is used in conjunction with the film removing teeth, that is, when the film removing impeller passes through the film removing impeller driven by the film removing chain, the top of the brush on the film removing impeller can brush to the root gap of the film removing teeth. the

The film collecting box 6 is welded on the frame 1, and the upper opening of the film collecting box 6 is located directly below the film unloading impeller 28, and is used for containing the residual film recovered. the

Ground wheel 15 axles are fixed on both sides of frame 1 by sleeve 27 structure, and sleeve 27 is provided with a group of bolt holes along vertical direction, can adjust ground wheel 15 heights by the installation position of ground wheel axle on sleeve 27. the
