Embodiment Construction

[0022] The present invention is described in detail below in conjunction with accompanying drawing:

[0023] like figure 1 , The vertical side length of the coreshare type seeding opener is H=80~140mm, the horizontal side length is L=130~170mm, and the radius of curvature of the ridge line is R 1 =250~350mm, the surface shape of the scale-shaped geometric structure 7 is a symmetrical hexagonal structure: side length L1=1~20mm, L 2 =1~30mm, inner angle α 1 =120~130°, inner angle α 2 =100-110°, the convex-hull geometric structure 8 is similar to an inverted butterfly, the top circle radius R=1-4mm; the bottom circle radius R+r=5-10mm; the convex-hull height h=1-4mm. The distance L between the centers of the two bionic structures, the scale-shaped geometric structure 7 and the convex-hull geometric structure 8, is 5-25mm.

[0024] like Figure 5 , the thickness of the conventional substrate 9 is D=2~4mm, and the height H of the scale-shaped geometric structure 7 1 =1~4mm, s...

Abstract

The invention relates to a bionic core moldboard type sowing boot which belongs to the technical field of agricultural machinery. The bionic core moldboard type sowing boot is based on the scale surface structure and the bulge-shaped structure of a soil cave animal pangolin, has the characteristics of abrasion resistance, visbreaking and drag reduction and is determined according to optimized analysis and geometric measurement. The scale-shaped geometric structure and the bulge-shaped geometric structure are regularly distributed on the upper surface of the front base body of a core moldboard; the center distance L between the scale-shaped geometric structure and the bulge-shaped geometric structure is 5-25 millimeters; and the scale-shaped geometric structure, the bulge-shaped geometric structure and the base body are processed into an integer. The bionic core moldboard type sowing boot disclosed by the invention has good technical effect of reducing the soil adhesion and the working resistance and can enhance the sowing and fertilizing quality and reduce the power consumption.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a bionic coreshare type sowing ditch opener. Background technique [0002] In agricultural cultivation operations, it is necessary to form a ditch on the surface of the land for sowing and fertilizing. Agricultural production requires that the ditch opened by the sowing opener be neat in shape, consistent in depth and uniform in sowing. However, under different soil conditions, the furrows formed by the seeding openers are very different. When it works in the soil with high humidity, the soil adheres to its working surface, which leads to increased traction resistance, and the shape of the groove is irregular, which makes the depth of the seeds in the groove inconsistent, which affects the quality of sowing. Therefore, reducing viscosity and drag is an important problem that should be solved for sowing openers. Contents of the invention [0003] Th...
