Elastic press roller with soil crashing function

Abstract

The invention discloses an elastic press roller with the soil crashing function. The elastic press roller is composed of a hub welding device, a hole structure elastic body and a soil crashing device. The elastic press roller works and walks forwards under the action of external force; when encountering large soil blocks, grid bars of the soil crashing device crush the soil blocks to make soil fine, grid bar structures are pressed into soil, the hole structure elastic body on the surface of the press roller makes contact with the soil to produce interaction force, the hole structure elastic body elastically deforms and twists, the deformed and twisted parts, separated from the soil after making contact with the soil, of the hole structure elastic body reset under the action of the elasticity of the hole structure elastic body, the soil falls off from the surface of the press roller, and the soil is pressed tightly. The elastic press roller is simple in structure, convenient to operate, high in practicality and wide in application range; the slip rate can be reduced, the operation quality can be improved, the operation energy consumption can be reduced, the operation efficiency can be improved, the adherency degree of the press roller with the soil in the operation process can be reduced, the large soil blocks produced in the operation process can be crushed, and the pressing force of the press roller to the soil can be reduced.

Description

technical field [0001] The invention relates to a pressing roller, in particular to an elastic pressing roller with the function of crushing soil. Background technique [0002] The pressure roller is a common soil-contacting part in agricultural machinery. It is mainly used for compacting the soil after plowing and sowing operations. As an important technical link in dryland operations, pressure rollers after sowing are used to increase soil compaction and reduce moisture in the soil. evaporation; reduce the large pores in the soil, so that the seeds are in close contact with the surrounding soil, which is conducive to the germination and emergence of the seeds, and spring sowing suppression can also increase the ground temperature. The shape of the existing pressure roll is a spinning body, which is traditionally cylindrical, and the cylinder becomes a pressure roll when it is placed horizontally. The material is mostly cast iron or low-carbon steel. The gravity or externa...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the soil on the surface of the seed is easily stuck together when the above-mentioned pressing roller is working, which increases the disturbance and damage to the soil, causes serious soil moisture loss, affects the germination and growth of the seed, and produces a large slip rate. And provide a kind of elastic pressure roller with crushing soil function
