SOILS AND SNOW-ICE FORMATIONS RESISTANCE TO CUTTING MEASURING BENCH Russian patent published in 2018 - IPC G01N3/58 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the equipment, which is used for the soils and snow-ice formations to resistance cutting forces measurement, acting on the earth-moving or snow-plowing machines cutting body at various cutting angles and the working body installation in the form of a blade. Bench contains a frame (6) with brackets (8), (9) rigidly fixed thereon, the pivotally connected to the frame U-shaped resilient cantilever element (7), pivotally connected to the U-shaped resilient cantilever element base (10), fixed on the base holder (11) with a working body (12) and horizontal tie-rods (13), (15), (20) with strain gages mounted thereon, registering the cutting force components. Holder (11) with the fixed thereon working body (12) is mounted on the base (10) with possibility of the working body angle changing during the holder rotation in the horizontal plane relative to the vertical axis, passing through the base center and the working body edge middle part, and the working body is installed with possibility of the cutting angle changing relative to the vertical axis. AT that, the holder (11) is connected to the base (10) by means of bolted joints (28), diametrically located around the said vertical axis and formed in the made in the base and the holder holes, wherein in the holder additional fixing holes (29) are made. In addition, the holder (11) is made with rigidly fixed brackets (30), on which the working body (12) is suspended by means of bolted connections (31). At that, the brackets (30) are provided with equidistant from the cutting edge mounting holes (32), located along the working body rotation radius relative to the cutting edge.

EFFECT: expansion of the bench functionality and increase in its operation efficiency in studying of the soils and snow-ice formations resistance to cutting effect on the working bodies.
