Compound type impurity-removing and primary cleaning vehicle for mechanically-recovered film residues in cotton field

Abstract

The invention discloses a compound type impurity-removing and primary cleaning vehicle for mechanically-recovered film residues in a cotton field. The vehicle is mainly composed of a tractor, a traction device, a feeding device, a staggered multi-screen-body vibration device, a special-shaped disc type separation device, a belt type friction film collecting, bundling and automatic film unloading device, a transmission system, a power system, a walking device, a rack and the like. The feeding device mainly comprises a material collecting mechanism and a belt conveyor, and can be used for intensively containing a recovered film and impurity mixture and conveying the film and impurity mixture backwards. The staggered multi-sieve-body vibration device mainly comprises a vibration driving crankshaft, a vibration driven crankshaft, an impurity removing sieve body and the like, and is used for vibrating, scattering and separating the conveyed film and impurity mixture and throwing the film and impurity mixture backwards. The special-shaped disc type separation device mainly comprises a rotating shaft and a special-shaped disc mounted on the rotating shaft, performs secondary separation onfilm residues and impurities leaking from the lower portion of the impurity removing screen body, and backwards conveys the film residues to the belt type friction film collecting, bundling and automatic film unloading device. The belt type friction film collecting, bundling and automatic film unloading device mainly comprises a hydraulic cylinder, a friction belt, a film collecting support and afilm winding roller, and the cleaned residual films falling from the tail end of the staggered multi-screen-body vibration device and conveyed from the tail end of the special-shaped disc type separation device are rolled and bundled. A compound structure is adopted for separating the impurities from the mechanically-recovered film residues in the cotton field, the impurities contained in the mechanically-recovered film residues in the cotton field can be effectively removed, and a foundation is laid for follow-up film residue processing and recycling.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a compound cleaning vehicle for the initial cleaning of residual film collected by a cotton field machine. Background technique [0002] While plastic film mulching cultivation technology can increase crop production and income, the problem of plastic film residues has also brought many hazards to the agricultural production environment and the ecological environment. The contradiction between the use of plastic film and the protection of the agricultural ecological environment and the green and sustainable development of agriculture has become increasingly prominent. The treatment of residual film pollution is a systematic project, and the resource utilization of residual film is an important part of the control of "white pollution". [0003] In recent years, the state and governments at all levels have increased their support for residual film recycling technol...

Problems solved by technology

However, the residual film after mechanical recycling contains a large amount of impurities such as cotton stalks and soil. If the recycled residual film is directly transported to the residual film processing and reuse enterprise, the impurities such as cotton stalks and soil will be transported away at the same time, which will increase the The transportation costs are increased, and the resources of returning cotton stalks to the field are wasted. Moreover, after the residual film is separated from impurities, impurities such as cotton stalks and soil need to be further processed, which is time-consuming and laborious.
