DEVICE FOR DETERMINING FORCES ACTING ON THE WORKING MEMBER OF AGRICULTURAL MACHINES FROM THE SOIL, MAINLY IN SOIL CHANNEL Russian patent published in 2022 - IPC G01L5/16 

FIELD: machine building; agriculture.

SUBSTANCE: invention relates to the field of agricultural machine building, in particular to the design of measuring devices for studying the loading of working elements of tillage tools, using soil channels. Device includes working element installed on movable driving trolley with intermediate frame, and measuring links. Intermediate frame is made triangular with rigidly connected vertical and horizontal beams. At least two linear bearings are arranged on each of the beams. Moving rods of vertically arranged bearings are rigidly connected to vertical post of bogie, and their outer casings - to vertical beam of frame. Working member is rigidly fixed on a movable rod of a horizontal pair of linear bearings, and external races of horizontally located linear bearings are rigidly connected to horizontal beam of frame. Measuring links are hinged between casings and moving rods of linear bearings parallel to their axes.

EFFECT: simplification of design and improvement of accuracy at measurement of forces acting on working element of agricultural machine in horizontal and vertical directions.
