BENCH FOR MEASUREMENT OF SOIL CUTTING RESISTANCE FORCE Russian patent published in 2019 - IPC G01N3/58 

FIELD: measurement technology.

SUBSTANCE: invention relates to measurement of soil resistance digging. Proposed bench comprises supports, levers, guide rails, strain gage, drive with traction winch and screw drive. Guiding rails are connected to levers for inclination of strain-gauge trolley with working element. One end of levers forms an axis of rotation with supports, the second end of levers is connected to drive rods with screw thread, which are equipped with support and lifting nuts with angles. Driving rods are connected to supports, and supports with holes at the edges are connected to the base, the working member is connected to the holder of the tenzometric trolley, which on one side forms an axis of rotation with the frame of the tenzometric trolley, and on the other side of the holder there is a hole which is coaxially fixed with holes on the frame by means of a bolt joint for changing the angle of gripping of the working member.

EFFECT: possibility of changing the gripping angle and inclination of the earthmoving machine working tool and possibility of working in laboratory or field conditions.
