example

[0021] Two kinds of subsoiling shovel handles are designed and manufactured based on the two types of shovel tip structure dimensions and frame connection section dimensions stipulated in the Machinery Industry Standard of the People's Republic of China JB / T9788-1999 "Shovel Shovel and Shovel Handle".

[0022] 1. Light deep loose shovel handle

[0023] The known quantity is the design plowing depth D = 290mm. Deduct the working height of the subsoiling shovel tip according to the designed plowing depth D, and obtain the height D1 of the inner alignment PQ = 231.168mm.

[0024] ① by the equation y 1 = 5.3074 x 1 4 / D 1 3 - 14.4421 x 1 3 / D 1 2 + 13.8507 x ...

Abstract

A resistance-decreasing bionic shovel shaft for loosening soil deeply is composed of a connection segment for connecting machine frame, working segment and shovel tip connecting segment. It features that the ratio of the forwad extended quantity of shovel shaft to the loosened depth is 0.68-0.95, the equation for determining the internal and external reference curves of said working segment is disclosed, and the resistance is decreased by 3-8%.

Description

technical field [0001] The invention relates to a subsoiling shovel handle on agricultural tillage machinery. Background technique [0002] Practice has shown that the main energy consumption of agricultural tillage machinery components during operation is to overcome the resistance from the soil. However, subsoiling equipment is the equipment with the largest energy consumption per unit of tillage width in the field operation machinery. Subsoiling equipment can only be operated by traction with high-power tractors. High energy consumption and poor farming economy have seriously restricted the popularization and promotion of this farming system. . If the drag reduction performance can be improved on the premise of ensuring the quality of soil subsoiling, it will be of great significance for saving energy consumption, reducing the configuration level of supporting power and expanding the application range of subsoiling tillage technology. [0003] The working resistance, so...
