Suspension type soil loosening device for restoring vegetation of project slash

Abstract

The invention discloses a suspension type soil loosening device for restoring vegetation of a project slash, belonging to the technical field of efficient soil loosening devices. A suspension mechanism is used for connecting a tractor with a harrow body through a connecting mechanism, the connecting mechanism comprises a first connecting rod and a plurality of second connecting rods, the harrow body is connected with the upper end of the suspension mechanism through the first connecting rod and is vertically connected with the lower end of the suspension mechanism through the second connecting rods, and harrow teeth are arranged on the harrow body. The suspension type soil loosening device is reasonable in design; by utilizing a steel structure, the integral structure is relatively firm; by replacing an existing furrow plowing manner, the soil loosening area is large; and the lengths of the connecting rods on two sides are different, and the middle connecting rod forms a certain tilt angle with the harrow body, so that harrowed stones can be timely discharged along the tilt angle, and the harrow leakage is prevented; and by repeatedly carrying out harrowing and suspending, a soil loosening purpose is achieved.

Description

technical field [0001] The invention relates to a hanging type loosening device for vegetation recovery on engineering ruins, and belongs to the technical field of high-efficiency loosening devices. Background technique [0002] A large number of engineering constructions on the Qinghai-Tibet Plateau have formed secondary bare land such as large-area borrow pits and spoil pits, which not only caused the fragmentation of the natural landscape along the line, but also caused the degradation of permafrost, affecting the stability of the permafrost environment, thus affecting the ecological environment of the Qinghai-Tibet Plateau. Safety has a very negative impact. The construction process not only destroys the original vegetation, but also destroys or removes the soil together with the original plant seeds and propagules. Part of the sandy mudstone is exposed to the ground, and its structure is compact and hard. The destruction of the topsoil layer leads to the lack of plants....

AI Technical Summary

Problems solved by technology

[0004] The gravel and silt in the project site are full of gravel and sand, and the structure is compact and hard. Generally, common soil plows are used for vegetation restoration, and then the soil is loosened and crushed. However, there are a lot of hard materials such as gravel in the project site. Plows are easily damaged or even snapped completely, making vegetation recovery difficult
