Bionic sub-soiling shovel

Abstract

The invention relates to a sub-soiling shovel. The sub-soiling shovel consists of a shovel handle, a shovel tip fixed at the bottom of the shovel handle and a pair of wing shovels symmetrically arranged on the left and right sides of the shovel tip; the front end face of the shovel handle is designed with a farming drag reduction structure which is a soil guiding plate fixed on the front end faceof the shovel handle, and the two sides on the front end face of the soil guiding plate are inclined; the upper surfaces of the wing shovels are also designed with the farming drag reduction structures, the drag reduction structures are six wavy strips that are different in length, are fixed on the surfaces of the wing shovels and are equidistantly distributed along the length directions of the wing shovels, and the tops of the wavy strips are in arc shapes; the surface of the shovel tip is designed with the farming drag reduction structure as well, the farming drag reduction structure imitates the body surface geometrical features of soil cave animals and aquatic scallops and is designed as ribs equidistantly distributed on the surface of the shovel tip, and bumps are uniformly distributed on the surfaces of the ribs so as to further play the role of crushing and removing soil to achieve drag reduction effects; the edges of the wing shovels are in S shapes; and the bottom surface of the shovel tip is an arc-shaped curved surface, so that high-to-low smooth transition from the front end to the rear end of the shovel tip can be realized. The related sub-soiling shovel is small in cultivation resistance, so that soil can be easily loosened and broken, and the sub-soiling quality of the soil can be enhanced.

Description

technical field [0001] The invention belongs to the field of agricultural tillage machinery, and in particular relates to a bionic subsoiling shovel. Background technique [0002] Subsoiling technology is an important method of conservation tillage that has been vigorously promoted at home and abroad in recent years. It mainly uses subsoiling shovels and other loosening parts to deeply loosen the soil and break the hard and dense plow bottom layer, which can deepen the plow layer, reduce soil bulk density, and improve soil quality. Soil permeability, which is conducive to crop development and increased yield. The subsoiling shovel is the key soil-contacting part of the subsoiling machine. During the subsoiling operation, it is subjected to high soil cultivation resistance and severe wear on the tip of the subsoiling shovel, which shortens the service life of the subsoiling shovel and increases the resistance of the subsoiling operation. The energy consumption increases, the...
