FIELD: machine building; agriculture.
SUBSTANCE: invention relates to agricultural machine building, in particular to measuring devices for investigation of traction resistance of working elements of tillage tools. Device includes working element installed on vehicle with intermediate frame and measuring link. Frame of the agricultural machine is equipped with a pair of bearings, in the inner races of which cams with pins are mounted, on which the intermediate frame is hinged. Measuring link is made in the form of a strain gauge beam connected to the intermediate frame by means of a hinged lead located horizontally relative to the soil surface. Cams pins are located at the lower point of the circle on the vertical axis of the bearing cross-section, and the hinged leads are located horizontally relative to the soil surface.
EFFECT: simpler design and higher accuracy when measuring forces acting on a working member of an agricultural machine in a horizontal direction.
