PLANER WORKING MEMBER POSITION CONTROL DEVICE Russian patent published in 2003 - IPC

FIELD: peat industry, road building, transport, agriculture. SUBSTANCE: proposed control device contains signal and reference transducers arranged square to each other and mounted on working member, loop antenna installed on surface to be treated and control unit. Signal transducers are mounted on working member and are arranged tangentially relative to one of equipotential lines formed by loop antenna and corresponding as to equidistance to cross profile of machined surface. Said signal transducers are installed on working member at angle from 0o to 20o to horizontal of working member. Width of loop antenna is defined by preset convexity of machined surface. EFFECT: improved accuracy of planning owing to planning of convex surface automatically according to program of changing of angular and height coordinates at each new pass. 3 cl, 1 dwg
