Plastic film residue recovering and straw returning combined machine

Abstract

The invention belongs to a plastic film residue recovering and straw returning combined machine comprising a rack, a driving system and a hydraulic system; the rack is provided with a plastic film collecting box; a straw smashing and returning mechanism is arranged below the rack; and a plastic film picking-up mechanism is arranged at the rear of the plastic film collecting box. Two operations including plastic film residue recovering as well as straw smashing and returning can be finished at a time; plastic film residues in the plastic film collecting box can be compacted by using a compression method, so that the plastic film residue loading capacity of the plastic film collecting box is increased; the plastic film residues in the plastic film collecting box are discharged by a telescopic frame which is simple in plastic film discharging operation; and an impurity clearing mechanism is arranged below the plastic film picking-up mechanism, so that falling impurities can be conveyed totwo sides of the machine in time by a conveying mechanism. Compared with the prior art, the plastic film residue recovering and straw returning combined machine is used for not only increasing the production efficiency, but also increasing the economic benefit.

Description

technical field [0001] The invention belongs to crop harvesting machinery, in particular to a combined operation machine for recycling residual film and returning straw to the field. Background technique [0002] Since the 1980s, plastic film mulching cultivation technology has been popularized and applied on a large scale in my country, especially in cold crop areas and arid areas. Plastic film mulching cultivation technology has the functions of heat preservation, moisture retention, moisture conservation, and inhibition of weed growth. However, there is a lack of effective recycling methods for the mulch film covered by farmland, resulting in a large amount of residual mulch film in the farmland soil, which causes serious soil pollution and has a serious destructive effect on crop growth. In order to solve the problem of residual plastic film pollution, people have proposed to use mechanical equipment to recover residual plastic film. Practice has proved that the method i...

Problems solved by technology

[0003] According to the state of residual film recovery, it can be divided into film collecting machine and residual film picking and recycling machine. The film collecting machine has no film collecting box, and the residual film is piled into strips according to a certain working distance during operation, and then Use manual or loading machinery to clear the film stack out of the field. The residual film piled up by strips contains a lot of impurities, and a second pick-up operation is required. The operation efficiency is low and the operation effect is not ideal.

The residual film picking and recycling machine is generally equipped with a film collecting box. The residua
