INSTALLATION FOR SPATIAL DYNAMOMETER OF HINGED AGRICULTURAL MACHINES AND TOOLS Russian patent published in 2019 - IPC G01L5/13 G01L5/16 G01L25/00 G01L5/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the construction of measuring instruments for studying the loading of the working bodies of tillage implements. This technical result is achieved by the installation for spatial dynamometer hinged agricultural machines and tools containing a tractor attached to the hinges of its hinged system through the strain gauge fingers intermediate plate. Strain gauge fingers are equipped with levers connected by rods with levers mounted on the intermediate shaft plate. Additional lever of the intermediate shaft interacts through the thrust with the middle of the rocker. At both ends of the rocker in opposite directions secured rods of hydraulic cylinders, rigidly mounted on the intermediate plate. Above-mentioned hydraulic cylinders are hydraulically connected with two hydraulic cylinders attached to the tractor frame, on the rods of which there are copiers lean upon soil. Ratio of the lengths of the levers and the distance between the copiers is connected by mathematical dependence.

EFFECT: reduction of the error of the dynamometer of the working bodies during the operation of the tractor unit.
