Abstract

The invention relates to a bionic rolling rake based on soil biological characteristics, and belongs to the field of agricultural soil preparation machines. The rolling rake comprises a rolling basket, a bionic rake blade and a rack; the rolling basket is arranged on the rack, the bionic rake blade is arranged on the rolling basket, and the bionic rake blade comprises a soil touching surface witha bionic ribbed scale structure and a cutting edge with a bionic sawtooth structure. According to the soil touching surface with the bionic ribbed scale structure, the shape of a scale is oval, x2/a2+y2/b2=1, a is the long axis and is 5 mm-15 mm, b is the short axis and is 5 mm-110 mm, the thickness H of the scar is 0.5 mm-2 mm, the bionic ribbed scale structure is arranged on the scar, and the ribbed section is a semicircle, a triangle and a quadratic function curve; according to the cutting edge with the bionic sawtooth structure, the shape of sawtooth is symmetrical in two sides and is a cubic function curve. The bionic rolling rake can reduce 3%-5% of working resistance and 5%-16% of wear rate, and the certain wear resistance and resistance reduction effects are achieved.

Description

Technical field [0001] The invention relates to a bionic rolling harrow based on soil biological characteristics, belonging to the technical field of agricultural soil preparation machinery. Background technique [0002] With the development of integral combined working tools, the use of rolling harrows is becoming more and more common, and its structure is becoming more and more diversified according to different farming requirements. To a certain extent, the rolling harrow has the functions of both a suppressor and a harrow, which can break the surface of the soil to form a loose, fine and flat surface, in order to preserve moisture, and can also compact the lower layer of soil, increase capillary action, and make the lower layer The rise of soil moisture is conducive to seed germination. However, at present, there is a large adhesion between the rolling harrow and the soil during the working process, the serious wear of the rolling harrow blades and the large operation resist...
