Saddle type rice transplanter

Abstract

The invention provides a saddle type transplanting machine comprising a traveling body and a transplanting operation unit at the rear portion thereof, and a hydraulic cylinder for lifting the transplanting operation unit, a microcomputer for controlling the hydraulic cylinder, and an electromagnetic valve; wherein, the traveling body is driven in a manner of static hydraulic type stepless transmission and can move forward and backward through pedal type HST pedal; furthermore, a touch operating arm is arranged in the front of the driving seat for simultaneously controlling the lifting of the transplanting operation unit, the cut-in of the transplanting clutch, and the operation of the left and right marker. The transplanting machine of the invention can simultaneously perform steering, speed shifting, and transplanting operation, thereby it has the effect of improving the driving convenience for the driver. In addition, a speed shifting detection sensor is arranged on the pedal type HST pedal so as to interlink with the hydraulic sensor (sensitive at low speed and non-sensitive at high speed) of the transplanting operation unit according to the acceleration / deceleration of the forward / backward, therefore the operation accuracy of the transplanting machine can be improved.

Description

technical field [0001] The invention relates to a ride-on rice transplanter equipped with a hydrostatic stepless speed change device capable of forward and reverse rotation, in particular to using a foot-operated HST pedal to change speed when moving forward and backward, and using a touch (touch) type operating lever It is a ride-on rice transplanter that performs the operation of the rice transplanting operation department so that the steering, speed change, and operation of the rice transplanting operation department can be performed at the same time. Background technique [0002] Fig. 1 shows the riding type rice transplanter of general structure, as shown in Fig. The running body part 10 such as a board and a panel, and the rice transplanting operation part 20 including a seedling mounting part 21, a float 22, and the like are connected in a mutually swingable state. [0003] In addition, the paddy field that carries out rice transplanting operation is made of hard soi...

AI Technical Summary

Problems solved by technology

[0031] However, in the above-mentioned riding-type rice transplanter in the prior patent application, since the operation trajectory for operating the steering wheel and the operation trajectory for operating the control button of the rice transplanting operation part and the control button of the marker are overlapped, there is an operator In the process of operating the steering wheel, the control button of the rice transplanting operation department or the control button of the marker is misoperated by mistake

[0032] In addition to this problem, most operators tend to use one hand to operate the steering wheel. Therefore, when the steering wheel and the body of the ride-on rice transplanter shake due to uneven hard soil layers, errors occur more frequently. operational problems

[0033] In particular, in this prior art, when the steering wheel is operated, the position of the control button of the rice transplanting operation unit and the control button of the marker are rotated together with the steering wheel around the axis of the steering wheel, so the driver operates the steering wheel while operating the steering wheel. In fact, it is very inconvenient and very difficult to operate
