Analysis and Test of Drive Rake Rotary Tiller Based on EDEM
In order to improve the efficiency and breaking rate of the power-driven rake in the process of breaking soil,based on the existing structure,studied the principle of the power-driven rake in breaking soil,constructed and analyzed the dynamic model of the soil breaking rake-soil,and designed the length and angle of the power-driven rake.At the same time,EDEM software was used to carry out response surface simulation analysis test with dynamic driving rake blade rotation speed,rake blade camber angle,rake blade length as the influencing factors,and the broken soil rate as the detection target.The test results showed that the rotation speed of the rake had a very significant impact on the rate of broken soil,external inclination angle and length had a significant impact on the rate of broken soil.When the rake angle was 34.7°,the rake speed was 320 r/min,and the rake length was 28 cm,the rake device was in the optimal working state,which can provide reference for the development and research of power-driven rake.
