【Abstract】 In view of the problems such as shallow tillage depth and poor maneuverability using existed micro-cultivator in tobacco fields in hilly and mountainous areas which can not meet the technical requirements of tobacco planting, a remote control crawler-type deep plow suitable for tillage in tobacco fields in hilly and mountainous areas was designed combined with the needs of conservation tillage in tobacco fields. The structure of the whole plow was designed, and its working principle was expounded. The rotary blade was optimized by numerical simulation. An innovative transmission based on ball screw driving synchronize shifting was proposed and its structure was designed, working process was analyzed. The research on intelligent transmission and machine control system was carried out to realize real-time remote control of machine operation by mobile phone or remote control mode, so as to reduce the labor intensity of control and to improve the production efficiency. The cultivated land test was carried out in the experimental field of hilly and mountainous areas, and the qualified rate of tillage depth was taken as evaluation criterion. The test results showed that the deep plow had good operation performance, the transmission shifted smoothly, and the average qualified rate of tillage depth of the whole machine was 93.3%, which met the requirements of soil preparation for tobacco planting, thus verifying the accuracy and rationality of the theoretical analysis and design of the machine.The research results can provide reference for the research of deep plowing machine in hilly and mountainous tobacco fields.更多还原
