Abstract

In order to solve the problems of inconvenient operation and easy loss of control levers in traditional tracked harvesters, this paper designs a hydraulic-driven chassis based on steering wheel control, and the structure and working principle of the chassis are described. The parameters such as track grounding length and drive wheel diameter are calculated; the design of the hydraulic drive system of the chassis is completed, and the driving control strategy is proposed. The test results show that the maximum speed of the chassis is 0.79 m/s, the minimum turning radius is 766 mm, and the failure rate tobacco rod clamping in field tests is only 4.37%. This design meets the needs of field operations, with high operability, stability, and ability, providing theoretical and practical basis for the development of tracked tobacco leaf harvesters.
