example

[0024] Taking the realization of the maximum tillage depth of 400mm as an example, the subsoiling shovel handle is made of Q275 steel not less than GB / T 700, and the width of the shovel handle is L. 2 The values ​​of σ and thickness σ are 75mm and 30mm respectively, and the connection holes or fixtures are designed according to the installation requirements of the rack structure. Rack Connection Section H 1 The structural size range is 255mm. Shovel tip connecting section L, L 4 and bolt hole L 1 The values ​​are 130mm, 145mm and 40mm respectively.

[0025] The inner directrix BC is determined by the polynomial equation The formed curve is obtained by taking the end point B on the inner directrix as the center of rotation and rotating ε in the counterclockwise direction at an angle of 40°. The calculation table of the x and y coordinates (unit: mm) of the BC segment is as follows:

Abstract

The invention relates to a sliding-cutting type resistance-reducing deep loosening shovel in the field of agricultural ploughing and soil preparation machinery. The sliding-cutting type resistance-reducing deep loosening shovel comprises a shovel handle and a copy shovel point connected to the shovel handle through bolts, and is characterized in that: an included angle (alpha) between a shovel point mounted plane (RC) of a shovel point connecting section and the horizontal plane is 20-24 degrees; a sliding-cutting angle (beta) formed between a tangent line of an internal directrix (BC) of a hook-shaped working section at an upper end point (B) and the vertical plane is 30-40 degrees; and the internal directrix (BC) of the hook-shaped working section is a curve formed according to a polynomial equation. Compared with the conventional other types of deep loosening shovels in the market, the sliding-cutting type resistance-reducing deep loosening shovel has the advantages that: the farming resistance is reduced, and the working resistance is obviously reduced particularly when the deep loosening depth and the operating speed are increased, so that energy is saved; meanwhile, large soil blocks and large gaps formed on the earth's surface after deep loosening operation are reduced, so that the earth's surface is flat and the loss of soil and water is prevented.

Description

technical field [0001] The invention relates to a subsoiling shovel in the field of agricultural tillage and soil preparation machinery. Background technique [0002] Traditional farming operations will form a hard plough bottom, which will affect soil water storage and moisture retention, and easily cause problems such as soil erosion and soil degradation. Subsoiling technology is one of the important agricultural conservation tillage techniques, which can solve the adverse consequences of traditional arable land operations and provide a technical guarantee for the sustainable development of agriculture. However, the energy consumption of the subsoiler is relatively large, especially with the increase of the subsoil depth and the forward speed of the machine, the traction resistance of the tool increases significantly. Therefore, reducing the tillage resistance of the subsoiler is of great significance for saving energy. [0003] The subsoiling shovel is a protective tilla...
