AI Technical Summary

Problems solved by technology

The stubble breaking part is a key part of straw and root stubble treatment in the process of no-tillage operation. During the operation, it will suffer from the combined resistance of straw, root stubble and soil, resulting in poor stubble breaking effect and easy wear and tear of the parts.

Embodiment Construction

[0047] The present invention will be further introduced below in conjunction with the accompanying drawings.

[0048] Such as figure 1 Shown, the present invention comprises the following steps:

[0049] 1.1 as figure 1 and figure 2 As shown, the geometric shape of the bionic stubble breaking knife is composed of the knife body 1, the handle 2 and the blade angle 5. Its structural characteristics are obtained from the study of the structural and morphological characteristics of the upper jaw teeth of longhorn beetle larvae and adults. The above The incisor part of the molar tooth is a bionic prototype, which is finally obtained through measurement, fitting, analysis and optimization of the cutting edge curve, cutting edge angle and cross-sectional structure, in which: the front profile of the cutter body 1 consists of ba curve, amn curve, np straight line, pr The arc line and the rb straight line are sequentially connected, and the middle part of the front of the cutter bo...

Abstract

The invention relates to a design method of a biomimetic stubble cutter and belongs to the technical field of agricultural machinery. The design method comprises the following steps: designing the geometrical shape of the stubble cutter: the stubble cutter comprises a cutter body, a cutter handle and a bezel; designing a plane M by constructing an equation of the plane M on the cutter body; designing a hook face N by constructing the equation of the plane N on the cutter body; designing an outer cutting edge curve B of the stubble cutter by reducing or enlarging a constructed prototype curve a0b0 equation; designing a curve D and a curve G; and designing the bezel through the constructed equation of the gradient-type bezel. According to the stubble cutter designed by the invention, the energy consumption can be saved in the operation process, and the operation efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a design method of a bionic stubble cutter. Background technique [0002] The no-tillage sowing operation is carried out under the condition that the surface is covered with straw and stubble, and the treatment of the surface straw and stubble before sowing can provide good operating conditions and seedbed environment for subsequent sowing operations and seed growth. The stubble breaking parts are key components for straw and root stubble processing in the no-tillage operation process. During the operation, they will suffer from the combined resistance of straw, root stubble and soil, resulting in poor stubble breaking effect and easy wear and tear of the parts. Therefore, in order to ensure its good operating performance, service life and economic performance, it is necessary to have good cutting performance, high wear resistance, and simple processing...
