Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. like figure 1 and figure 2 As shown, the design of the bionic shark skin surface structure of a deep loosening shovel described in the present invention, the non-smooth surface of the bionic shark skin, and the national standard double-wing subsoiling shovel are characterized in that: additive manufacturing is carried out by the SLM150 metal 3D printer, and the surface is rough degree of processing. The arrangement direction of the surface structure is arranged along the horizontal direction in the projection direction of each shovel surface. The movement is driven by the national standard subsoiler shovel handle. The fixed connection is an ordinary bolt connection.

[0019] When the subsoiler shovel moves in the soil, the soil moves along the arrangement direction of the bionic shark skin on the surface of the subsoiler shovel. The bionic sharkskin...

Abstract

The invention discloses a design of a subsoiler simulating a sharkskin surface structure. The design comprises a bionic shark non-smooth surface protruding modeling method, scaling and an arrangementdirection in contact with the surface of the subsoiler, and is characterized in that the bionic sharkskin surface has a certain size requirement and shape requirement. The bionic sharkskin surface structure fits the surface of the subsoiler in a certain direction. The design has the advantages of extracting the surface characteristics of the sharkskin, reducing positive pressure of the subsoiler in contact with soil, having certain guidance quality to the soil and reducing the frictional loss of subsoiling.

Description

technical field [0001] The invention relates to the design of a bionic shark skin surface structure of a subsoiling shovel, relates to the technical field of soil subsoiling, and in particular relates to a non-smooth surface design and coupling technology of a bionic shark skin structure. [0002] technical background [0003] Subsoiling the cultivated land can deepen the plowing layer, improve the soil structure and loosen and ventilate. Subsoiling will not overturn the soil layer, so that the vegetation on the soil surface is still on the soil surface, which is conducive to protecting the soil from excessive wind erosion. Subsoiling can improve water storage capacity. The water storage capacity of subsoiled soil is twice that of shallow plowing, and can increase the water permeability of different types of soil by 5-7 times. Using subsoiling shovels for subsoiling can improve the water storage capacity of the soil and help alleviate the erosion of the soil by surface runof...
