Residual film recovery device

Abstract

The invention provides a residual film recovery device. Energizing coils are energized with high-tension current of a constant frequency so that one ends of permanent magnets have magnetic poles opposite to or same as magnetic blocks, so that a moving rod vertically moves on a sliding rail, crushing teeth and digging shovels crush and dig the soil on a screen when moving downward, and broken filmin the soil is also further broken, the crushing teeth wound by the coils adsorb the broken film when crushing the broken film, therefore, the improvement of crushing and digging of the soil and the adsorption of the broken film in the soil can be achieved by energizing the coils, a driving device of a soil improvement device does not need to be additionally arranged, and a motor drives a plurality of film removing wheels to recycle and collect the residual film on the crushing teeth after adsorption.

Description

technical field [0001] The invention relates to the field of plastic film technology, in particular to a residual film recycling device. Background technique [0002] Mulch film is the ground covering film. Mulch film can maintain soil moisture, increase soil temperature, maintain soil structure, prevent pests from invading crops and diseases caused by certain microorganisms, etc. However, after harvesting crops, there are more and more residual mulch film fragments in the soil. Therefore, the problem of residual film recycling is becoming more and more serious. When recycling foreign plastic film, the whole plastic film is collected by winding device. It is required that after one year of use, most of the residual film remains in the soil. At present, most of the domestic residual film recycling methods are film-picking type, drum type, telescopic cylinder type, sprocket type, wind suction type, etc., but these residual film Most of the film recovery devices have the disad...

[0002] Mulch film is the ground covering film. Mulch film can maintain soil moisture, increase soil temperature, maintain soil structure, prevent pests from invading crops and diseases caused by certain microorganisms, etc. However, after harvesting crops, there are more and more residual mulch film fragments in the soil. Therefore, the problem of residual film recycling is becoming more and more serious. When recycling foreign plastic film, the whole plastic film is collected by winding device. It is required that after one year of use, most of the residual film remains in the soil. At present, most of the domestic residual film recycling methods are film-picking type, drum type, telescopic cylinder type, sprocket type, wind suction type, etc., but these residual film Most of the film recovery devices have the disadvantages of low recovery efficiency, complex structure, and environmental pollution. There are also electrostatic collectors in the prior art. The invention patent application with the publication number CN107371408A discloses an electrostatic separation and recovery device for farmland plastic film. The DC high-voltage generator power supply is connected to the high-voltage signal, and the body is fixed on the tractor, and the residual film with a small area is electrostatically adsorbed while plowing the plowed layer of soil. The publication number is CN106171069A, which discloses a farmland surface residual film recovery device. The arc-shaped cylinder is connected with hydraulic components, the film is cut with a disc knife, and the finely divided film is adsorbed by an electrostatic generating device. However, most of the electrostatic film absorbing devices in the prior art also use engine hydraulic cylinders to work, which is harmful to the environment. Pollution, and the absorption of fine mulch in the soil is not clean, and there is no breaking and turning device for the soil itself
