Traction-type residual film recovery compression and straw returning combined operation machine

Abstract

The invention discloses a traction type used plastic film retrieving compressing and straw mulching combined machine. The combined machine comprises a universal joint shaft, an electric control system, a hydraulic system, a used plastic film collecting and compressing part, a straw grinding mulching part and a used plastic film curling and retrieving part, wherein the straw grinding mulching part is positioned under the front of the used plastic film collecting and compressing part, and the used film curling and retrieving part is positioned behind the used film collecting and compressing part; the straw grinding mulching part is connected with a film collection tank of the used plastic film collecting and compressing part through a four-bar mechanism; two ends of an adjusting cylinder I are respectively hinged with the straw mulching machine and the film collection tank; the upper part of the used film curling and retrieving part is hinged with a used plastic film collection device; and the middle part of the used film curling and retrieving part is connected with the used plastic film collection device through an adjusting cylinder II. The used plastic film retrieving compressing and straw mulching combined machine has a large-volume film collection tank, can be used for furthest improving the loading capacity of the film collection tank, and is especially suitable for large strip field operation in farms of the Xinjiang Production and Construction Corps.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a traction-type combined operation machine for recovering and compressing residual film and returning straw to the field. Background technique [0002] The problem of farmland residual film pollution control was raised almost when plastic film was first introduced into China and applied to cover crops. It has been more than 30 years since then. With the raising of this problem, the residual film pollution control technology has gradually developed, and the recovery of residual film by mechanical means is one of the technologies, and it has been used until now. From the point of view of film collection, there are two kinds of residual film recovery machines with film collection box and without film collection box. Residual film recovery machines with film collection boxes such as Chinese patents CN205124271 U, CN 105191526 A, CN 205052084 U, etc., and r...

AI Technical Summary

Problems solved by technology

The residual film recycling machine without a film collecting box cannot travel very far and must put down the picked up plastic film and accumulate it on the ground, otherwise, it will not work normally; and the residual film accumulated on the ground needs to be transported out by other vehicles Outside the field, this virtually increases the burden and cost of farmers

Ordinary residual film recycling machines with film collecting boxes cannot make very large film collecting boxes due to their own structure and other factors, usually no more than 4m 3 , and there is basically no compaction device. The length of the strip field of Xinjiang Production and Construction Corps farms is generally more than 1 km. Before reaching the ground, the film collecting box is full, and the work has to be stopped, and it is specially driven to the ground to unload the membrane, which causes waste of power and affects the working efficiency of the machine tool

Chinese patents CN 205030061 U and CN 205030062 U disclose the film-pressing technology of the film collecting box of the residual film recovery machine respectively adopting the working principle of the four-bar mechanism and the cam mechanism, but the application of these technologies in the recovery of residual film has poor applicability , Reliability is not high and other issues, can not really be used in practice
