Anti-drag low-soil-disturbance bionic subsoiler

Abstract

An anti-drag low-soil-disturbance bionic subsoiler belongs to the technical field of agricultural machinery and is characterized in that 10-25 triangular prisms I evenly distributed are fixedly and symmetrically connected to two sides of a base from bottom to top within the total height, the triangular prisms I in operating state are arranged with vertical axes parallel to the horizontal direction, and the lowermost triangular prism I is 10-30 mm away from the bottom end of the base; 3-10 triangular prisms II evenly distributed are fixedly and symmetrically fixed to the upper surfaces of leftand right wings of a dual-wing tip; length 110 of the triangular prisms II and I varies with lengths of the left wing 4 and right wing 6 of the dual-wing tip B; the cross section of each of the two types of triangular prism is in isosceles triangle shape; a ratio of spacing of every two triangular prisms to their height is 0.5-0.6; included angle beta 1 between a slant of the front end of each triangular prism and the horizontal plane is 15-30 degrees. The anti-drag low-soil-disturbance bionic subsoiler has the advantages that tilling drag can be reduced, economic benefit of conservation tillage is increased, soil disturbance coefficient occurred is very small, the soil structure is good for growths of roots, and stress tolerance of crops can be improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a bionic deep loosening shovel with resistance reduction and low soil disturbance. Background technique [0002] Due to the increasingly serious soil compaction and the deepening and thickening of the plow bottom layer, the resistance to deep plowing is significantly increased, and the wear is also more serious, which will increase the working resistance of the machine and fuel consumption, thereby reducing the economic benefits of conservation tillage. However, too high energy consumption hinders its further popularization and application, so reducing drag, saving energy, and improving farming quality have attracted widespread attention. Contents of the invention [0003] The present invention designs a bionic subsoiling shovel with a triangular prism structure, the purpose of which is to reduce tillage resistance, produce the largest plow bottom soi...
