Problems solved by technology

However, when such a pressure roller works, it is easy to stick the soil on the surface of the seed, which increases the disturbance and damage to the soil, causes serious soil moisture loss, affects the germination and growth of the seed, and increases the working resistance when the adhesion phenomenon is serious. When necessary, it needs to be shut down for cleaning, which reduces the operating efficiency
In addition, when sowing, it is easy to cause a large number of soil clods, coupled with the influence of stubble and weeds, the seeds cannot be in good contact with the surrounding soil

Abstract

The invention relates to a surface soil compacting roller with a bionic geometric structure, belonging to the field of agricultural machinery. By using the surface soil compacting roller, the problems that soil adheres when the compacting roller operates can be solved, and frictional acting force between the surface of the compacting roller and the contacted soil is regulated so as to regulate the compactness of the compacted soil, improve operation quality, save operation energy consumption and improve operation efficiency. In the surface soil compacting roller, structure along the alignment of the compacting roller or circumferentially continuous structure or interrupted rib-shaped structure is adopted; in the interrupted rib-shaped structure, even distribution, staggered distribution or random distribution is adopted, rib height is 5-50mm, height is 10-50mm, the length of the interrupted rib structure is 10-100mm, rib space between the continuous rib structure and even-distributed or staggered-distribution interrupted rib-shaped structure is 0-50mm; and the upper contour of the rib cross section adopts rectangle, circular arc, convex parabola shape, convex sinusoid, triangle or waviness.

Description

technical field [0001] The invention relates to an agricultural machinery tillage part for compacting soil, in particular to a soil pressing roller with a bionic geometric structure surface, which belongs to the field of agricultural machinery. Background technique [0002] The pressing roller is a commonly used agricultural machine. Its main function is to suppress the soil, especially the soil after sowing, so that the seeds are in close contact with the soil, prevent the soil moisture from being lost too quickly, protect the soil moisture, and facilitate seed germination and emergence. tidy. Soil suppression is an important link in crop production and one of the important factors affecting crop yield. The shape of the existing pressure roller is a spinning body, which is traditionally cylindrical, and the cylinder is placed horizontally to become a pressure roller, and its material is mostly cast iron or low-carbon steel. However, when such a pressure roller works, it i...
