DEVICE FOR MEASURING THE HORIZONTAL FORCE FROM AN AGRICULTURAL MACHINE MOUNTED ON A TRACTOR Russian patent published in 2022 - IPC G01L5/13 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to the field of agricultural engineering. A device for measuring horizontal force from an agricultural machine mounted on a tractor includes an intermediate frame mounted on the lower and upper links of the three-point hydraulic hitch system of the tractor, carrying two-arm levers hinged coaxially on the intermediate frame, and a measuring tool. The free ends of the two-arm levers, the axes of rotation of which are located vertically, are connected to the lower links of the hydraulic hitch system and are provided with gear sectors paired with each other. On the rotation shaft of one of the levers connected to the lower rods, a gear wheel is installed, coupled with a pinion mounted on a vertically located axis of rotation of the crank connected to the upper link of the hydraulic hitch system. One end of said double-arm lever shaft is rigidly fixed to the base. The measuring means is made in the form of a torque sensor placed between the gear wheel and the end of the shaft rigidly fixed on the intermediate frame.

EFFECT: increased accuracy of measuring horizontal force from a mounted agricultural machine or tool.
