Description

Technical Field

[0001] This utility model belongs to the field of agricultural residual film recycling technology, specifically relating to a residual film recycling device that also has a screening function. Background Technology

[0002] With the widespread adoption of plastic film mulching technology, the problem of "white pollution" in farmland has become increasingly serious. Residual plastic film damages soil structure and hinders crop growth, making its recycling and management urgent. Existing residual film recycling devices mainly employ principles such as drum rakes or air suction, which can achieve preliminary recycling, but generally suffer from a key technical bottleneck: the recycled material contains a large amount of soil, crop stubble, and straw, resulting in a high impurity rate in the residual film. This not only directly affects the subsequent resource utilization value of the recycled residual film, as high-impurity residual film is difficult to directly recycle; but also, the mixed impurities increase the load and power consumption of the device, and easily cause problems such as entanglement and blockage, affecting the continuity and reliability of the recycling operation. Currently, residual film collection and impurity screening are mostly treated as two separate operations, with recycling preceding screening, resulting in a cumbersome and inefficient process. Therefore, developing an integrated equipment that can achieve efficient film-impurity separation simultaneously with residual film recycling on-site, realizing integrated "recycling-screening" operations, is of vital practical significance for improving the quality of residual film recycling, reducing subsequent processing costs, and promoting sustainable agricultural development. This utility model addresses this technical pain point and aims to provide an innovative solution. Summary of the Invention

[0003] The purpose of this utility model is to provide a residual film recycling device that also has a screening function. First, the rotary tillage mechanism tills and breaks up the soil. The conveying mechanism picks up the residual film, mixed soil, straw, etc. from the surface and transports them to the crushing mechanism. The three rows of crushing blades in the crushing mechanism make the residual film break up evenly. At the same time, small particles such as soil fragments are initially separated through the upper screen. The remaining materials are conveyed into the screening mechanism by belt conveyor. At the entrance of the screening mechanism box, wind screening is used to blow the residual film into the box. Impurities other than the residual film fall to the ground surface by their own weight through the channel, which further separates the film from the impurities. The residual film that enters the box is initially degraded by the liquid extracted by the liquid tank and sprayed evenly by the nozzle.
