Bionic digging shovel blade for potatoes

Abstract

The invention discloses a bionic digging shovel blade for potatoes. The bionic digging shovel blade comprises a shovel handle, the front end of the shovel handle is provided with a shovel tip, and theshovel tip comprises an upper shovel face and a lower shovel face; the upper shovel face comprises a curved segment AB and a curved segment BC which imitate the outer contour of a first toe of a front paw of a mole; the lower shovel face includes a curved segment DE and a curved segment EF which imitate the inner contour of the first toe of the front paw of the mole; the front end of the shovel tip is provided with a combined wedge-shaped cutting edge. According to the bionic digging shovel blade for the potatoes, the upper and lower shovel faces adopt bionic designs of the outer and inner contours of the first toe of the front paw of the mole respectively, dug-out soil is bent and crushed in a lifting process of the shovel faces, the effect of digging the crushed soil is achieved, and the digging resistance of a digging shovel is reduced. The combined wedge-shaped shovel tip has an obvious cutting effect on the soil, and not only is good resistance reduction performance achieved butalso a certain soil crushing effect is achieved. The bionic digging shovel blade for the potatoes is convenient to disassemble and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a potato bionic digging shovel. Background technique [0002] At present, in the process of harvesting potato crops, the quality of the digging shovel directly affects the overall performance and use of the harvester. The existing bionic excavation shovel has a simple structure, a single function curve of the bionic shovel surface, and poor soil crushing ability; in the process of excavating potatoes, the excavation shovel has relatively large excavation resistance and high energy consumption, which is easy to cause the excavation shovel to be worn; excavation Most of the connections between the blade and the frame are welded and fixed. When the excavating blade is damaged during work, it is inconvenient to disassemble and maintain, and even the entire excavating blade needs to be replaced, which is expensive. [0003] Studies have shown that the mole has well-dev...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the above-mentioned deficiencies in the prior art, a potato bionic digging blade provided by the present invention solves the problems of the existing digging blades such as poor soil crushing ability, large resistance, high energy consumption, and easy wear and tear of the digging blade.
