Coupling bionic resistance-reducing viscosity-reducing ploughshare

Abstract

The invention discloses a coupling bionic resistance-reducing viscosity-reducing ploughshare. The coupling bionic resistance-reducing viscosity-reducing ploughshare comprises a ploughshare main body and bionic claw toes; the surface of the ploughshare is coated with one layer of polytetrafluoroethylene coating; the outline of the cross section of the bionic claw toe single body consists of three curves; the thickness of the bionic claw toe single body is 50 mm; bionic claw toes are distributed on the vertical middle line of the concave surface of the ploughshare at equal intervals of 50 mm; the bionic claw toes are made of cast steel; the thickness of the polytetrafluoroethylene coating is 30 microns; coating is conducted by a chemical vapor deposition method. The polytetrafluoroethylene is typical super-hydrophobic coating, has high adhesiveness and can volatilize toxic substances at high temperature. The temperature of the working environment is below 30 DEG C, so the condition that the coating volatilizes the toxic substances is avoided. Not only pollution to soil components but also influence on the subsequent crop tillage is avoided.

Description

technical field [0001] The invention relates to a subsoiling plowshare on agricultural machinery, in particular to a coupled bionic drag-reducing and viscosity-reducing plowshare, which belongs to the technical field of agricultural machinery. Background technique [0002] The plow is a soil tillage machine whose main function is to turn the soil and has the functions of loosening and crushing the soil. The plowshare is the most important part of the plow, which determines the depth and effect of loosening the soil. Existing plowshares are basically similar to shovel heads in appearance, and generally have defects such as excessive traction resistance, serious wear of plowshares, serious adhesion of wet soil, and unsatisfactory subsoiling effect. The traditional improvement method is mainly to increase the number of plowshares to increase the efficiency of subsoiling; to increase the active traction of subsoiling to overcome the resistance of plowshares; to remove a part of...

AI Technical Summary

Problems solved by technology

Although the above traditional improvement methods have reduced the resistance of the plowshare and the adhesion of wet soil to a certain extent, there are still some problems: high operating cost and poor economy; incomplete loosening of the soil and ineffective deep loosening; The service life is greatly reduced, etc.
