Farmland arable layer used plastic film collector

Abstract

The invention discloses a farmland arable layer used plastic film collector which comprises a framework. A traction frame is arranged at the front end of the framework along the advancing direction ofthe collector, a transmission system, a depth regulating mechanism, a film stripping shovel blade, a film soil conveying mechanism and a film collecting box are further arranged on the framework, thetransmission system is connected with an external driving mechanism and drives the film soil conveying mechanism, the height difference between the depth regulating mechanism and the film stripping shovel blade can be adjusted, the film stripping shovel blade is arranged at the front end of the film soil conveying mechanism, and the film collecting box is arranged at the rear end of the film soilconveying mechanism. The farmland arable layer used plastic film collector is simple and reasonable in structural design, convenient to regulate and strong in pertinence. As the soil penetration depth of the film stripping shovel blade can be regulated, superficial plastic films can be picked, plastic films of 0-20cm arable layers can be picked, soil and impurities are sufficiently cleaned by multi-stage conveying and soil pulverizing rollers, and the picked plastic films are low in impurity rate.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a machine for recovering residual film on farmland plow layers. Background technique [0002] Film-covering cultivation is a production-increasing technology. This technology was introduced into our country in the late 1970s and early 1980s. The application and popularization of this technology not only greatly increase the yield of economic crops, but also in arid and semi-arid areas and alpine areas, enabling various crops to obtain a bumper harvest. At present, my country is the country with the largest amount of plastic film in the world. Since the plastic film we use is a polymer compound (polyethylene), it is a kind of material that is difficult to biodegrade. Therefore, in the farmland covered with plastic film for a long time, the residual film in the soil will accumulate more and more, resulting in the decline of the quality of the cultivated land and th...

Problems solved by technology

These three models can only clean the residual film on the shallow surface (0-5 cm depth), the recovery volume is limited, the operation effect is not good, and there is no film collecting box, the residual film picked up will fall off at any time
