Stalk crushing returning and residual plastic film recovery combined machine

Abstract

The invention relates to a machine used for the combined operation of chopping crop straws and returning farmland and recycling residual films on the ground surface. The machine comprises a traction unit (1), a transmission system (2), a frame (3), a residual film box (4), a land wheel (10), a scarifier tyne (11), a straw chopping device and a residual film recycling device; the straw chopping device consists of a reciprocating cutterbar (13), a transverse conveying belt (12), a disc type chopper (14), a protection hood (16) and a transmission device; wherein, the residual film recycling device is arranged at the back of the residual film box and consists of a chain harrow (6), an elastic gear (7) for raking the film, a bottom board (9) and a feeler wheel (8); a gear rod (5) is arranged on the chain harrow, and the elastic gear (7) for raking the film is arranged at the back side of the residual film recycling device. The machine can finish the two operations of returning the straws to the farmland and recycling the residual films, has the advantages of high operation speed, clean residual film recycling, small energy consumption and film-rod separation; moreover, the residual films are hard to twist working parts; therefore, the demands of chopping the straws and recycling the residual films can be met.

Description

technical field [0001] The invention relates to a machine for crushing and returning farmland crop straws to the field and recovering residual film on the surface, in particular to a combined operation machine for crushing and returning straws to the field and recovering residual film. Background technique [0002] At present, due to the large-scale promotion and use of plastic film cultivation technology, farmland is seriously polluted by residual film. In order to solve the problem of residual film pollution, a variety of residual film recovery machines have been developed at home and abroad. 4JSM-1800 Residual Film Recycling Combined Operating Machine and 4FS2 Plastic Film Recycling Machine are only used to recycle residual film. There are MSM-3 Residual Film Recycling Machine at Seedling Stage and MS-2 Residual Film Recycling Machine for Corn Seedling Stage, which are used for harvesting After harvesting, there are 1ZSM-800 residual film recovery machine, 1MC-70 plastic ...

AI Technical Summary

Problems solved by technology

[0003] The above straw crushing and returning to the field and residual film recovery combined operation machine mainly use vertical axis type slinger or horizontal axis type slinger to crush straw, and use "shovel type" or "tooth type" mechanism installed in front of residual film box to recover residual film. This kind of operation method has high energy consumption for crushing straw, and the operation speed of residual film recovery is low, while the operation speed of straw crushing is high. The speeds of the two do not match, resulting in a decrease in the operating efficiency of the whole machine, and the residual film is easy to wrap around the working parts

After the crops are harvested, it is the best time to recycle the residual film. Due to the presence of straw in the field, it is difficult to simply recycle the residual film. Therefore, it is of great significance to develop a combined operation machine with high efficiency that can crush the straw and return it to the field and recycle the residual film.
