Problems solved by technology
[0003] There are also motor-controlled speed control handles in the existing equipment, but in most structures, manual control and electric control cannot be used at the same time, or a clutch structure needs to be added to realize the use together. The structure is complicated, the cost is high, and the operation is inconvenient.

The invention relates to a manual-automatic integrated control assembly. The assembly comprises a rack, an operating rod, a rotating arm, a transmission rod, a motor and a transmission mechanism, wherein the operating rod is arranged at the upper end of the rotating arm, the transmission rod is hinged to the lower end of the rotating arm, a shaft is arranged on the rack, the rotating arm and the transmission mechanism are both arranged on the shaft, the transmission mechanism comprises driving pieces and driven pieces, the rotating arm is fixed to the driven pieces, the multiple driving pieces and the multiple driven pieces are arranged alternately, the driving pieces and the driven pieces are pressed tightly through elastic assemblies, and the motor is fixed to the rack and drives the driving pieces to rotate. The operating rod can be manually controlled and can also be driven by the motor, and meanwhile, due to the fact that the transmission mechanism adopts the mode that the driving pieces, the driven pieces and friction pieces are pressed tightly through the elastic assemblies, when the force of manual operation is larger than the static friction force among the driving pieces, the driven pieces and the friction pieces, the effect that manual operation is preferential can be achieved.
Description
technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a hand-automatic integrated control assembly. Background technique [0002] HST stepless transmission has been widely used in agricultural machinery, such as crawler harvesters, crawler rotary tillers, high-speed rice transplanters, etc. The speed control handle drives the rotation of the extended shaft of the HST gearbox through the linkage mechanism, so as to control the driving speed of the vehicle. The current speed control handles are generally operated manually. Considering the changeable soil conditions in paddy fields, the harsh working environment, and easy slippage, the rice transplanter for production is completely operated manually, which is labor-intensive, low-efficiency, and excessively high-quality. Relying on the operator's operation skills, the driver is very prone to fatigue after long-term boring follow-up driving, which will have a great imp...
