DEVICE FOR DETERMINING THE HORIZONTAL FORCE FROM A MOUNTED TILLAGE TOOL Russian patent published in 2022 - IPC G01L5/13 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to the field of agricultural engineering, in particular to the study of the loading of the working bodies of mounted agricultural machines and tillage tools, and can be used to measure the horizontal force from such tools. The device contains a strain gauge plate and a force measuring element. The device is equipped with left, right and upper double-arm levers pivotally fixed on the strain gauge plate, to the outer ends of which the tractor hydraulic suspension system rods are attached. The inner ends of the left and right double-arm levers are interconnected by means of a ball bearing. The outer bearing cage is provided with an external spherical element interacting with an internal spherical element made at the end of the fork. The fork is pivotally connected to the inner end of the upper lever, which is connected to the force measuring element. The swing axes of the left and right levers are located vertically, and the swing axis of the upper lever is located horizontally and perpendicular to the longitudinal axis of the tractor.

EFFECT: simplifying the design and increasing the accuracy of measuring the horizontal forces acting on the tillage tool.
