Profiling bionic press roller

Abstract

The invention discloses a profiling bionic press roller in order to solve the problems that soil adheres to the surface of the body of a press roller commonly used in the prior art, the compactness of the pressed soil is not even, and the pressing force of the press roller on soil is not sufficient. The profiling bionic press roller comprises a press roller body and a center shaft, bionic elastic pieces are distributed on the surface of the press roller body, a shaft ring is fixedly installed on the center shaft, elastic spokes are installed between the shaft ring and the bionic elastic pieces, the elastic spokes on the roller body are in the shape of a profiled ostrich claw toe outline, and designed according to the process that claw toes make contact with soil in the running process of ostriches, the elastic pieces are inserted into soil in the movement process, not only is good soil fixing effect achieved, but also the press roller can be effectively prevented from sliding, ground profiling is performed through stretching and shrinking of the elastic spokes, the compacting effect on soil is better, and pressure is larger; a nylon layer is formed on the surface of the press roller through heat treatment, and thus soil will not adhere to the press roller in the working process.

Description

technical field [0001] The invention belongs to a profiling and bionic pressing roller in the technical field of agricultural machinery. Background technique [0002] The pressure roller is a kind of agricultural machinery. Its function is to compact the soil after sowing, so as to increase the density of the soil to facilitate the maintenance of soil moisture and facilitate the germination and emergence of seeds. Before the application of pressure rollers, farmers stepped on the soil after planting and relied on the gravity of the human body to compact the soil. This method is inefficient and the soil compactness is uneven. People invented the pressure roller to replace the manual compaction of the soil after sowing. Present pressing roll is made up of roll frame and several rollers that are arranged on the roll frame, and the axis of its roller is perpendicular to the longitudinal axis of roll frame (ie the advancing direction of roll frame). During operation, the pressu...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects of sticky soil, uneven compaction of soil after compaction and insufficient pressure of the compaction roller on the soil in the commonly used compaction rollers, and provide a bionic compaction roller to reduce soil pressure. With the adhesion degree of the pressure roller, the compactness of the soil after the suppression is uniform, and the purpose of increasing the pressure of the pressure roller to the soil, the technical scheme of the present invention is as follows:
