Embodiment Construction

[0023] like figure 1 and figure 2 As shown, the present invention is composed of a shovel handle A, a shovel edge B, a bionic convex prism assembly C, a base body D and a shovel tip E, wherein the shovel handle A is a cube, and the shovel handle length is H 1 300-310mm, shovel handle width L 2 60-70mm, shovel handle thickness L 3 30-40mm; the tip E is a chisel-shaped subsoiling shovel tip in accordance with the JB / T9788-1999 standard, and the horizontal projection height H of the installation section of the tip E 3 80-90mm; the shovel handle A is fixed to the upper end of the base D and is perpendicular to the horizontal plane; the shovel edge B is fixed to the front of the base D; the shovel tip E is fixed to the front end of the base D; the distance between the installation plane of the shovel tip E and the horizontal plane The included angle α is: 15°≤α≤35°; the working length of entry into the soil is L 1 320-340mm; the 20-22 convex prisms of the left convex prism gro...

Abstract

The invention discloses a bionic drag-reduction subsoiler with low soil disturbance, belonging to the technical field of agricultural machinery. According to the invention, a shovel handle is fixedlyconnected with and arranged at the upper end of a base body and is perpendicular to the horizontal plane; a shovel blade is fixedly connected with and arranged at the front surface of the base body; ashovel tip is fixedly connected with and arranged at the front end of the base body; 40-44 convex prisms of left and right convex prism groups are uniformly distributed and fixedly connected with theleft and right sides of the base body; the convex prisms are parallel to the horizontal plane; the rear end surfaces of the left and right convex prisms are on the same vertical plane; and the crosssections of the convex prisms are isosceles trapezoids with fillets. In the working process of the bionic drag-reduction subsoiler, gaps can be formed when convex prism structures make contact with soil, and a generated normal adhesive force is far larger than a tangential adhesive force, so adhesion of an interface is damaged, and resistance is reduced. The bionic drag-reduction subsoiler provided by the invention is small in operation resistance, low in energy consumption, high in working efficiency, small in soil disturbance coefficient and capable of improving economic benefits of protective cultivation.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a bionic drag-reducing deep loosening shovel with low soil disturbance. Background technique [0002] With the continuous popularization and application of soil cultivation technology in the country, the land has put forward higher requirements for the cultivation quality and energy consumption of operations, especially for various soil working components. The subsoiler is the most important working part of the subsoiler. If the subsoiler is designed reasonably under the premise of ensuring the quality of cultivation, the operation resistance or energy consumption of the machine can be reduced, which is conducive to the promotion of subsoiler operations. The tillage resistance of the subsoiler shovel mainly comes from two aspects: one is the shovel handle; the other is the shovel tip. And relevant studies have shown that the operation resistance of the...
