DEVICE FOR DIFFERENTIAL CONTROL OF SOIL TREATMENT DEPTH DURING FRONTAL ROTARY INTERNAL SOIL TILLAGE IN SET WITH TRACTOR WITH STEP ELECTRIC CONTROL OF HYDRAULIC DISTRIBUTOR OF MOUNTED SYSTEM Russian patent published in 2010 - IPC A01B13/16 

FIELD: agriculture.

SUBSTANCE: device comprises sensor of vertical position of working tool of frontal rotary internal soil tiller relative to soil surface in the form of support element. Support element is connected to optical-mechanical sensors of its position relative to tiller frame. Device also has an optical-mechanical electronic sensor of tractor power take-off shaft inclination angle of +15° relative to longitudinal axis of tractor. Optical-mechanical electronic sensors are connected to information-logic electronic system to control specified depth of soil treatment. Information-logic electronic system of control is equipped with electronic key manipulators of pulse cyclic connection of regular step modes of tractor mounted system lifting and lowering. Frequency of tractor mounted system lifting mode actuation is set by information-logic electronic system of control as higher than frequency of tractor mounted system lowering mode actuation.

EFFECT: structural design will make it possible to control depth of soil treatment as the set is moving with high stability, quality and reliability.
