Transplanting clutching handle automatic gear shifting device of unmanned rice seedling transplanting machine and control method of transplanting clutching handle automatic gear shifting device

Abstract

The invention discloses a transplanting clutching handle automatic gear shifting device of an unmanned rice seedling transplanting machine and a control method of the transplanting clutching handle automatic gear shifting device. The transplanting clutching handle automatic gear shifting device comprises a gear shifting driving device and a longitudinal traction device; before rice seedlings are transplanted, a controller is used for calculating the position of a handle according to the position of a servo motor, which is detected by an encoder; whether the handle is at a neutral gear or not is judged; if the handle is at the neutral gear, a control instruction is sent by a vehicle-mounted computer; an upper computer, the controller and the like are used for controlling the servo motor andan electromagnet to move and the handle is turned to an original position; in a rice seedling transplanting process, ascending, descending and driving instructions and the like of a rice seedling transplanting part are sent to the controller through the upper computer; an instruction is generated by the controller and is transmitted to a driver and the traction type electromagnet, so as to drivethe servo motor to rotate and the electromagnet to do longitudinal traction motion, and drive the handle to finish gear shifting. According to the transplanting clutching handle automatic gear shifting device disclosed by the invention, transplanting clutching handle automatic gear shifting of the unmanned rice seedling transplanting machine can be realized and the transmission aim can be realizedwithout the need of damaging an original mechanical structure; the transplanting clutching handle automatic gear shifting device can be freely detached when automatic control operation is not used orthe rice seedling transplanting machine breaks down.

Description

Technical field: [0001] The invention relates to the technical field of agricultural machinery, and mainly relates to an automatic shifting device for a clutch handle of an unmanned rice transplanter and a control method thereof. Background technique: [0002] At present, the soil conditions in paddy fields are changeable, the working environment is harsh, and it is easy to sink and slip. The rice transplanter for production is completely operated manually, which is labor-intensive and low-efficiency. Moreover, the quality of work depends too much on the operator's operating skills, and the driver is boring for a long time. Boring follow-up driving is prone to fatigue, which will have a great impact on the accuracy of rice transplanting operations. It is prone to defects such as repeated operations, missing operations, and unstable quality of rice transplanting operations. It is difficult to meet the requirements of precise operations, resulting in reduced production. The op...

Problems solved by technology

However, most of the existing automatic shifting mechanisms are mechanical structures, which cannot accurately control the movement of the gears, causing large deviations when the unmanned rice transplanter is working.
