A self-propelled deep purification farmland residual plastic film recovery unit

Abstract

The invention relates to the field of agriculture mulch cleaning, recovering and recycling, and provides a self-propelled deep-purification farmland residual mulch recovery unit capable of recovering residual mulches buried underground. The unit has self-propelling power and comprises a car body, a rotary tillage system scarifying the mulches and soil, a conveying system scooping up and conveying the scarified mulches and soil, a separation system separating the soil from the mulches and a collecting and packing system collecting and packing the mulches; the rotary tillage system, the conveying system, the separation system and the collecting and packing system are installed in sequence from front to back along the car body. Compared with existing equipment, the structure is more compact, the unit has the self-propelling power, a driving system is reasonable in design, and the unit can move in farmland flexibly and has high practicability.

Description

technical field [0001] This patent relates to the field of cleaning, recycling and reuse of agricultural mulch film, more specifically, a self-propelled deep-layer purification of farmland residual mulch film recovery unit. Background technique [0002] Thirty years ago, the promotion of agricultural mulch film helped increase China's agricultural production and income. At present, my country's plastic film technology development and the use of covering plastic film have ranked first in the world. With the continuous promotion and application of agricultural mulch over the years, more and more mulch remains in the farmland, which cannot be degraded under natural conditions for hundreds of years, seriously polluting the environment. The hazards of residual plastic film are mainly manifested in the following aspects: first, destroying the soil structure, affecting the quality of cultivated land and the air permeability and water permeability of the soil, resulting in a decrea...

AI Technical Summary

Problems solved by technology

[0007] Even if the biodegradable mulch can be completely degraded, the application of the new mulch cannot reduce the waste film that has remained in the farmland, that is, the application of the new mulch cannot solve the problem of the mulch that has caused serious land pollution.

[0008] 2. The combination of manual and mechanical recycling takes a lot of manpower and material resources to recover the residual mulch film on the soil surface by hand or rake. The existing recycling waste film machinery is mainly tractor-pulled multi-layer comb-shaped rake or ring-shaped rolling nail-toothed type Residual mulch removal machine, there are also some new types of waste film machinery to recycle the mulch buried in the soil (0-8cm depth)

For example, the equipment involved in this technology adopts a trailer-type structure, without independent driving power, and needs to be dragged by a tractor or a car, which greatly increases the length of the equipment, and it is very inconvenient to turn around in the farmland

Secondly, many parts of the equipment need a lot of power to drive, but the structure of the equipment obviously cannot be driven by multiple oil extraction machines. If the traditional single diesel engine equipment is used, a complex transmission system is required to transmit power, which greatly increases the equipment cost. Difficulty in design and reliability in use

In addition, the recycled farmland mulch contains a lot of soil. In the process of separation, it is obviously not enough to rely on the wind force brought by the blades to drive the directional movement of the mulch film, resulting in poor separation effect.
