【Abstract】 In order to solve the problem of existing in the traditional plowing and rotary tillage, a kind of testing device of inclined screw integral parts was designed. The device could improve the working efficiency of the whole field, realize the belt and provide a good bed environment for the seed,and solve the problem of large energy consumption and low efficiency. By quadratic orthogonal rotating combination test method to machine speed, screw speed, the screw Angle of the grave, screw pitch,plow deeply test factors, the tested to break rate as the evaluation index. Experimental results showed that the machine speed was 0.75 m · s^-1; the screw rotation speed was 550 r · min^-1; the grave Angle was20°, screw pitch was 60 mm for the optimal structure parameters combination, and under the optimal structure parameters combination, the soil bin test, grounded at a rate of 92.54%. The key components of the design could improve the soil breaking rate and meet the requirements of the ground operation.The test results show that the indexes met the technical requirements of the relevant national indexes.The research could provide some references for the design of the helical screw.更多还原
