example 1

[0030] Example 1 see Figure 6 :

[0031] The vertical side length A of the opener is 108mm, the horizontal side length B is 170mm, the hypotenuse side length C is 253mm, the thickness H of the shovel body matrix is ​​2mm, and the material is ultra-high molecular weight polyethylene and its composite materials and other hydrophobic materials. It is integrated with the rib and bonded with the metal substrate. The height T of the geometric structure unit is 3mm, the width W is 10mm, the distance K between the edge end and the edge of the shovel body is 8mm, and the distance M between the convex ribs of the geometric structure is 20mm. The angle β between the convex rib and the soil cutting surface is 75°, and the angle θ between the two shovel blades is 25°.

Abstract

The present invention relates to agricultural machinery, is especially one kind of bionic furrow opener, and aims at solving the problems of furrow opener, including adhering soil, winding weed, great in resistance, etc. The bionic furrow opener consists of a base body and surface bionic geographic structure units basically. The surface bionic geographic structure units are fins distributed regularly on the surface of the base body, and the fins possess total projection areas on the surface of the base body accounting for the 50-100 % and certainly designed geometrical shape. Compared with available furrow opener, the bionic furrow opener of the present invention has less moving resistance and 10-35 % lowered power consumption.

Description

technical field [0001] The invention relates to a ditching part on an agricultural tillage machine, in particular to a bionic ditch opener. Background technique [0002] The ditching part is an important part of the sowing and fertilizing equipment. Its working performance directly affects the work of the seeder and the fertilizing machine. The balance, stability and power consumption of the whole machine. In the no-tillage and less-tillage sowing techniques, the problems of clay, entangled grass and increased resistance of the ditching parts are more prominent. The adhesion of soil to the surface of the ditching parts will make the grooves opened by the ditching parts irregular. Inconsistency in depth not only directly affects the quality of sowing and fertilization, but also increases the working resistance of the ditching parts. It can be seen that reducing viscosity and drag can not only improve the quality of sowing and fertilization, reduce the working resistance of ...
