BULLDOZER EQUIPMENT Russian patent published in 2017 - IPC E02F3/76 

FIELD: transportation.

SUBSTANCE: bulldozer equipment contains the following elements: a blade with butt faces with a frontal surface and a back side; pushing bars connected with the blade by hinges; hydraulic cylinders for lifting and lowering the blade; hydroscales changing the cutting angle of the blade; lateral cheeks hingedly fixed by means of brackets and bushings to vertical axes, installed on the butt faces of the blade; half-bottoms fixed with by means of hinges to the lower edges of the lateral cheeks. In the upper parts of the butt faces of the blade, the housings of hydromechanisms of lifting and lowering the lateral cheeks together with the half-bottoms are fixed with by means of swivels, and their rods are hinged to the brackets on the side cheeks. On each of the lateral cheeks, hydromechanisms of lifting and lowering the half-bottoms are installed with respect to the lateral cheeks. On the back side of the blade there are two hydromechanisms of turning the lateral cheeks with the half-bottoms in the horizontal plane, consisting of hydraulic cylinders, cranks and thrusts. Wherein the thrusts are attached to the lateral cheeks by means of ball joints, and the cranks and the housings of the hydraulic cylinders are fixed to the rear side of the blade using ball joints as well. On the adjacent faces of the half-days, butt connectors are made.

EFFECT: no need to upgrade for lengthening of the pushing bars impairing the conditions of cutting the blade into the soil and reducing the productivity; when digging the soil with a blade, in front of it there are no protruding equipment elements reducing the visibility for the machine operator and prone to breakage in contact with the soil.
