The invention relates to a steering system of a hydraulic driven rice transplanter. The steering system of the hydraulic driven rice transplanter comprises a left guide wheel and a right guide wheel, each guide wheel is provided with a guide wheel driving motor, the guide wheel driving motors are connected with a whole transplanter hydraulic oil circuit, wheel shafts of the guide wheels are respectively connected with a steering vertical column, the steering vertical column is connected with a rice transplanter frame in a rotation mode, and each steering vertical column is provided with a steering rocker arm. When the guide wheels are in forward positions, the steering rocker arms lean backward and form a 81-72-degree included angle with a central axis of the rice transplanter frame, the left side and the right side of the rice transplanter frame are respectively provided with a hydraulic oil cylinder which is connected with the rice transplanter frame in a rotation mode, piston rods of the hydraulic oil cylinders are respectively connected with a corresponding steering rocker arm, and the hydraulic oil cylinders on the left side and the right side of the rice transplanter frame are symmetrical relative to the central axis of the rice transplanter frame. The steering system of the hydraulic driven rice transplanter has the advantages of being convenient and smooth to steer and simple in structure.
Description
technical field [0001] The invention relates to a rice transplanter, in particular to a hydraulically driven rice transplanter. Background technique [0002] The full-hydraulic drive rice transplanter is a new field, and no such product has been found in the market at present. The inventor has recently developed a full-hydraulic rice transplanter. The drive of the wheels is completed by the drive motor, and the steering is driven by hydraulic components. The steering column for the guide wheels is completed. However, the existing steering method is that when turning to the left, the hydraulic element on the left side drives the guide wheel to turn an angle to the left, and the hydraulic element on the right side turns the corresponding angle at the same time, but according to the existing vehicle steering principle , to make it rotate more smoothly, the rotation angles of the two guide wheels are different, and the rotation angle of the outer wheel is smaller (because its t...
