Cultivation rotation working part with bionic geometric structure

Abstract

The present invention relates to a geometric structure of rotation working part of used for driving type rototilling-tillage machine, and especially to a cultivation rotation working part with bionic geometric structure. The invention takes the fore leg claw toe of mole with high-efficient digging capability as a bionic researching object, extracts the special geometric structure characteristic and applies the geometric structure characteristic for designing the rotation working parts (rotary blade or stubble breaking blade) on the cultivation machinery. The component is mainly composed of a side cutting surface with a side cutting edge, a front cutting surface with positive cutting blade, a transition surface for connecting the front cutting surface and the side back surface, and a transition edge for connecting the front cutting edge and the side cutting edge. The invention is characterized in that the front cutting edge (6) adopts a bionic circular arc structure. The geometric shapeis confirmed by the following equation: when the operation breadth of single blade of front cutting edge is L, the corresponding central angle of circular cutting edge is (theta), the corresponding radius is (r), and the number of circular arcs is (n), the corresponding expression is as follows: L / 2nr=sin(theta / 2). The cultivation rotation working part with bionic geometric structure according tothe invention can greatly reduce the energy consumption in cultivation operation under the precondition that the cultivation quality is ensured.

Description

Technical field: The invention relates to a geometric structure of a rotary working part for a driving type tillage and land preparation machine, in particular to a rotary working part for tillage with a bionic geometric structure, which belongs to the design technology of tillage machinery in agricultural machinery. Background technique: A rotary tiller is a tillage machine that shreds soil by power-driven working parts. It uses the compound movement of the rotation and forward movement of the blade on the cutter shaft to crush the uncultivated land and the cultivated land. Its performance is characterized by its strong ability to crush soil. One rotary tillage can achieve the effect of ordinary plows several times. After rotary tillage The fields can meet the requirements of sowing or transplanting. The rotary tiller has good working quality and high work efficiency. It can not only save time for farming, save labor, but also reduce the number of times the machine goes to...

Problems solved by technology

When agricultural machinery is working, the adhesion phenomenon caused by the contact between the surface of the soil-contacting parts and the soil will increase the working resistance, reduce the working efficiency and working quality, increase energy consumption, and increase the disturbance and damage to the soil at the same time, causing the soil to lose moisture Severe, even make the machine unable to work
