DESIGN, ANALYSIS AND TEST OF CLEANING MACHINE FOR GRAPEVINE COLD-PROOF SOIL.

In order to address the problems of low efficiency and low degree of mechanization of artificial soil clearing of the grapevines in spring in Xinjiang grape growing regions, a grapevine cold-proof soil clearing machine was designed. The machine is mainly composed of a frame, gearbox, suspension device, soil clearing parts, hydraulic system and mechanical transmission system, etc. The motion track of the soil clearing parts was analyzed to obtain the key factors affecting the performance of the grapevine cold-proof soil clearing machine that were determined. The three-factor, three-level quadratic regression orthogonal experiment was carried out with the forward speed, soil clearing parts' diameter and rotation rate of soil clearing parts as factors and the soil clearing distance was used as evaluation index. The results showed that the order of influence on the soil clearing distance was rotation rate of soil clearing parts > forward speed> soil clearing parts diameter. The parameters were optimized based on response surface method with the following results: the rotation rate of soil clearing parts speed was 277.7 r/min, the forward speed was 3.5 km/h, and the soil clearing parts diameter was 681.7 mm. The validation experiment was carried out with the optimal parameters' combination. The soil clearing distance was 85.44 cm, which was consistent with the predicted results of the model. This research results can provide reference for the development of other types of grapevine soil clearing machine. [ABSTRACT FROM AUTHOR]
