Bionic sub-soiling shovel with drag-reduction bionic surface

Abstract

The invention provides a bionic sub-soiling shovel with a drag-reduction bionic surface. The bionic sub-soiling shovel comprises blind holes, a cutting edge front outline line, an inner standard line,bionic convex edge strip structures, a first arc line, a second arc line, a cutting edge curved surface and a shovel body, wherein eight blind holes are distributed on the central line at the upper side of the shovel body; the blind holes are fixed on a rack through two bolts and are used for fixing the shovel body; the shovel body is provided with the cutting edge front outline line and the inner standard line; the cutting edge curved surface is formed by a curved surface between the cutting edge front outline line and the inner standard line; the cutting edge front outline line and the inner standard line are front cutting edge curves; the front cutting edge curves are bionic curves; the bionic convex edge strip structures with different heights are distributed on the surface of the shovel body; one side, close to the inner standard line, of each bionic convex edge strip structure is an inclined plane; the bionic convex edge strip structures are symmetrically distributed at two sides of the shovel body; a rear outline line is formed by the first arc line and the second arc line; the two arc lines are tangent. Compared with an international circular-arc-shaped sub-soiling shovel,the bionic sub-soiling shovel provided by the invention has the advantages that the working resistance can be reduced by about 17 percent, the disturbance quantity of soil is reduced, the energy consumption is reduced and the whole quality of the soil is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a bionic deep loosening shovel with a drag-reducing bionic surface. Background technique [0002] As a large agricultural country in my country, the advanced degree of agricultural mechanization determines the quality of agricultural operations, crop growth environment and the quality of later crop growth. However, soil compaction and the upward movement of the plow bottom make the growth of crops restricted, and the root system cannot penetrate below the plow bottom. When there is a lot of rain, the bottom layer of the plow blocks the penetration of rainwater, which will cause rotten roots; when there is little rain, the bottom layer of the plow blocks the rise of water under the layer, causing the crops to die due to lack of water. Subsoiling technology can effectively break the bottom layer of the plow, so that water and nutrients can be fully exchanged, promot...

AI Technical Summary

Problems solved by technology

[0003] At present, with the in-depth development of subsoiling technology, the problems in subsoiling are also becoming more and more prominent. First, the resistance of subsoiling is too large, resulting in high energy consumption

Since the plowing depth of the subsoiling operation is between 20 and 40 cm, the amount of soil disturbance is relatively large, and the traction resistance of the operation is relatively large,
