Abstract
PURPOSE: To keep the blade work under maximum work amount condition irrespective of quality of earth by controlling maintenance of blade in comparison of blade's work amount with its work amount after given hours.
CONSTITUTION: Trunnion 7 is equipped with traction detector 11 such as strain gauge. Detector of actual speed of vehicle 12 is composed of oscillator 12a and receiver 12b provided at the rear end of body 1. Tracting force F and actual speed of vehicle V are sent to operator 13, where work amount Q (Q=F×V) is detected through operation. Work amount Q thus obtained transmitted to comparator 14, where increase or decrease in work amount is estimated. The result of estimation is sent to blade cylinder controlling mechanism 15 to move blade 9 up and down, thus blade being controlled to work constantly under the condition of maximum work amount.
