Abstract
There is disclosed a plowing depth detecting system for a rotary plow adapted to detect an actual plowing depth on the basis of distance data with respect to the ground received from a distance sensor attached to the rotary plow which is vertically movably connected to a vehicle through a link mechanism. The distance sensor provides a microprocessor with distance data with respect to the ground rearwardly of the rotary plow. The microprocessor determines a value of actual plowing depth of the rotary plow on the basis of this distance data and a correction value according to a working condition of the rotary plow.
Claims11
A plowing depth detecting system comprising;
- a rotary plow vertically movably connected to a vehicle through a link mechanism and including a rotor for plowing ground,
- leveling means for leveling the ground plowed by said rotor,
- sensor means attached to said rotary plow for detecting a distance between said sensor means and the ground rearwardly of said leveling means, and
- processing means including;
- calculator means for calculating an amount of rise of the plowed ground leveled by said leveling means as compared with an unplowed ground,
- corrector means for determining a plowing depth correction value from said amount of rise of the plowed ground that is determined by said calculator means, and
- actual plowing depth determining means for determining an actual plowing depth of said rotary plow from distance data provided by said sensor means and said plowing depth correction value.
