A bionic digging shovel

Abstract

A bionic excavating spade comprises a spade body, wherein the two faces of the spade body are an inner soil contacting face and an outer soil contacting face respectively, the front end of the spade body is the soil entering end, the rear end of the spade body is a top wing, the middle of the top wing bends in an arc shape toward the inner soil contacting face, an inner excavating face is arranged on the spade body, extends to the top wing from the soil entering end and bends toward the inner soil contacting face, one ends of two boundaries of the inner excavating face and the outer soil contacting face are connected with the two ends of the arc bending part of the top wing, and the other ends of the two boundaries are tangent to the side edges of the spade body. The geometrical shape of the soil contacting surface of the spade is improved, so that anti-drag and desorption performance of the spade is improved, the problems that in the excavating process of the spade, the resistance is large, adhesive performance is high, and abrasion resistance is poor are solved fundamentally, compared with a traditional spade, the abrasion resistance of the bionic spade is improved by 50%, and the anti-drag and desorption performance is improved by 70%.

Description

technical field [0001] The invention relates to an excavating farm tool, in particular to a bionic excavating shovel. Background technique [0002] The shovel is a commonly used digging tool in our daily life, but in the process of excavating cultivated land and daily use, there are serious wear and tear, high digging resistance and unsatisfactory soil removal performance. Abrasion is one of the main reasons for the failure of ground-contact mechanical parts. In order to overcome this defect, the traditional method is to carry out surface hardening. At present, the commonly used surface hardening techniques include spraying, deposition, coating, etc., but because the thickness of the hardened layer is thin, It reduces the effectiveness of ground mechanical soil-contacting parts in abrasive wear conditions; and, the improvement of the surface hardness of engineering materials is also limited. In order to improve the above situation, people focus more on improving the stiffne...

Problems solved by technology

[0003] Since the drag reduction and wear resistance of the shovel is not only related to the material used, but also to the geometry of the surface in sliding contact with the soil. Low problem, providing a biomimetic digging shovel that improves the geometry of the shovel contact surface in the form of
