ROLLING CONTROLLER FOR TRANSPLANTING UNIT IN RIDING TYPE RICE TRANSPLANTER

摘要

PURPOSE: To provide the subject rolling controller equipped with a detector, etc., for detecting a ground contact pressure applied to side ground floats and capable of performing a highly accurate rice transplanting. ;CONSTITUTION: This rolling controller controls the pitching motion of a transplanting unit 21 based on a signal by a vertical motion of a central ground float 32. The controller is equipped with detectors (K1) and (K2) for electrically detecting the ground contact pressure applied to right and left side ground floats 35a and 35b and sending the signal detected by the right and left detectors (K1) and (K2) to a control unit 44. The control unit 44 compares and calculates the right and left detected values and the rolling motion system is controlled so as to keep the ground contact pressure of the right and left side ground floats 35a and 35b within a prescribed range. In this rolling controller, the values detected by the above-mentioned detectors (K1) and (K2) in a state where the right and left side ground floats 35a and 35b are suspended during the course of elevation and subsequent descent of the transplanting unit 21 are preset as an initial detection standard value in the memory of the control unit 44 and the rolling control is carried out based on this standard value.;COPYRIGHT: (C)1995,JPO
