Chain harrow type residual film picking mechanism and rotary tillage and residual film recovery all-in-one machine

Abstract

The invention discloses a chain harrow type residual film picking mechanism and a rotary tillage and residual film recovery all-in-one machine. The rotary tillage and residual film recovery all-in-one machine comprises a rack, a rotary tillage mechanism, a frame type tensioning mechanism, the chain harrow type residual film picking mechanism, an air conveying mechanism, an impurity removal and recovery mechanism and a film unloading mechanism. Rotary tillage is conducted through the rotary tillage mechanism, then film picking teeth stretch into soil subjected to the rotary tillage, residual films buried in a deep layer of the soil are picked up and conveyed upwards, the residual films are screened through a film guiding plate with holes, then the residual films are sucked by a draught fan and conveyed to a film collecting rolling cylinder through an air supply pipe and a pressure relief cover, and the residual films are screened again in the film collecting rolling cylinder to remove impurities. According to the rotary tillage and residual film recovery all-in-one machine, the residual films deep in the soil can be recovered, meanwhile, the phenomena of chain tooth clamping and tooth jumping are prevented, the shutdown maintenance time and cost are reduced, the recovery work efficiency is improved, and the residual film recovery rate is increased; in addition, the impurities in the residual films can be screened out in a multi-stage mode, and the cleanliness of the recovered residual films is improved, so that the number of impurity components in the residual films is small, transportation is convenient, and later impurity separation work is reduced.

Description

technical field [0001] The invention relates to the technical field of residual film recovery, in particular to a chain rake type residual film picking mechanism and an integrated machine for rotary tillage and residual film recovery. Background technique [0002] Mulch film is the ground covering film, usually transparent or black PE film, and there are also green and silver films, which are used for ground covering to increase soil temperature, maintain soil moisture, maintain soil structure, prevent pests from invading crops and diseases caused by certain microorganisms, etc. , the function of promoting plant growth. [0003] Although mulch can bring many benefits, but at the same time, because the mulch is not easy to decompose in the soil, the mulch remaining in the soil will cause the following hazards: 1. The residual mulch affects the physical properties of the soil and inhibits the growth and development of crops; 2. The soil seepage is due to Free gravity, the phe...

AI Technical Summary

Problems solved by technology

[0004] The current residual film recovery device is difficult to recover the buried and soil part of the edge, and it is even more difficult to recover the residual film remaining in the deep soil in the past, resulting in incomplete recovery of the residual film, and the residual film in the soil after recycling large

In addition, the existing residual film recovery device generally has residual film that is easy to form blockage, resulting in chain jamming and tooth skipping, increasing downtime and maintenance time and cost, affecting recycling efficiency, and there are many residual impurities such as sand and soil in the recovered residual film , not convenient for post-processing and recycling
