Description

Technical Field

[0002] The residual film recovery machine currently used in China is a single-piece conveyor screen, which is limited to the recovery of small-scale crop root and tuber stubble and residual film. Due to the use of a single-piece conveyor, the conveying load of the single-piece conveyor screen is too heavy during harvesting operations, and the middle part of the conveyor screen is prone to breakage, and the residual film will be entangled and unable to be separated, which not only affects production operations but also increases maintenance costs; the single-piece conveyor screen residual film recovery machine has a narrow conveyor screen width and low efficiency during operation, which seriously affects the work progress. When the single-piece residual film recovery machine is in use, the front end of the frame is easily caught by the residual film, which causes the tractor to be overloaded, resulting in reduced tractor production efficiency and increased production costs; in an environment where residual film and large root and tuber stubble are mixed, the residual film and soil cannot be separated, resulting in the conveyor screen being entangled and stagnant.
