METHOD AND DEVICE FOR CONTROL OF AGRICULTURAL OUTFIT AND ESTIMATION OF ITS PARAMETERS Russian patent published in 1994 - IPC

FIELD: agriculture. SUBSTANCE: information on changes of load is obtained from hydromechanical energy flow divider, using fluid pressure as controlled parameter and power control parameter simultaneously during lifting, correction of vertical loads and power control of implement. Energy flow is locked by operating members of lifting mechanism and by hydraulic control valves of steering and stabilization of support reactions. Speed is gradually increased by energy flow divider until the propelling forces are coordinated with resistance in the running gear and working tool drive. Energy flows in running gear and working tool drive are combined with each other and part of energy for servicing the outfit units is returned and added to main flow. No-load return of fluid during correction of vertical loads, power and position control of implement is brought down to zero. Energy is returned to positive-displacement coupling. Outfit control and estimation device of outfit comprises load sensor in the form of hydromechanical energy divider. Pressure line communicates with implement control system and pointer. EFFECT: higher efficiency. 5 cl, 12 dwg
