TILLING DEPTH DETECTING DEVICE FOR ROTARY TILLER

摘要

PROBLEM TO BE SOLVED: To detect the vertical tilting of a rear cover with a tilling depth sensor by connecting the tip end of a pressing rod supporting the rear cover to the tip end of the sensor arm of the tilling depth sensor through a flexible joint mechanism.;SOLUTION: A rear cover 19 supported by a pair of right and left pressing rods 21 is pivoted in a vertically tiltable manner to the rear end of a rotary cover 16 movable forward and backward and covering the upper part of the rotating orbit of a tilling tine 15a. A bracket 20 supporting the pressing rod 21 is fixed to the top of the rear end of the rotary cover 16, the tilling depth sensor 24 is attached to a bracket 22 connected to the front face of the bracket 20 and the tip end of the sensor arm 24b connected to the tilling depth sensor 24 is connected to the tip end of the pressing rod 21 through flexible joint mechanisms 21a, 24c to enable the detection of the vertical tilting of the rear cover 19.;COPYRIGHT: (C)2002,JPO
