DEVICE FOR DETERMINING THE HORIZONTAL FORCES ACTING ON THE WORKING BODY OF AN AGRICULTURAL MACHINE FROM THE SOIL Russian patent published in 2023 - IPC G01L5/16 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to measuring devices for studying the loading of the working bodies of tillage implements. The device for determining the horizontal forces acting on the working body of the agricultural machine from the side of the soil includes working body 7 and measuring link 4 installed on base 1 of the vehicle with intermediate frame 2. Intermediate frame 3 is equipped with a pair of hinged arms 6 and 11, the free hinges of which are fixed on base 1, and the measuring link 4 is mounted on strain gauge beam 3 rigidly fixed on intermediate frame 2. The second end of the strain gauge beam is pivotally connected to base 1 by means of horizontally located rod 5 of adjustable length. Said hinged levers 6 and 11 envelope the base and the intermediate frame in the transverse plane, forming a parallelogram mechanism with 90 degree angles between its links. The axes of rotation of the links of the parallelogram mechanism are parallel to each other and perpendicular to the direction of movement of the agricultural machine.

EFFECT: simplifying the design and increasing the accuracy of measuring the forces acting on the working body of the agricultural machine in the horizontal direction.
