INTEGRAL-MOUNTED PLOW HYDRAULIC CONTROL SYSTEM Russian patent published in 2004 - IPC

FIELD: agricultural engineering. SUBSTANCE: invention can be used in mounted hydraulic systems connecting tillage sets with traction device. Proposed hydraulic system includes linkage with plow and mounted system lifting and lowering power hydraulic cylinder, hydraulic distributor with two coils of electromagnetic shutoff valves hydraulically connected with hydraulic cylinder and hydraulic pump, and delivery and drain channels. Placed in plow space are selector switch one contact of which is connected with supply source and two contacts are connected with coils of electromagnetic shutoff valves of hydraulic distributor of integral-mounted plow hydraulic control system. Spring-loaded bushing is in direct contact with selector switch button being secured on pressure disk connected through corrugated sealing ring with surface of plow and being in contact with flexible plate cantilever mounted over disk. One end of said plate is rigidly secured on plow surface. EFFECT: provision of optimum penetration of plow to definite depth, improved operation of different soils. 6 dwg
