SU1434042A1 - Bulldozer equipment - Google Patents

Abstract

The invention relates to land excavation machines. The purpose of the invention is to reduce the energy intensity of the cutting process and the movement of the soil. Bulldozer equipment contains a blade with a knife 2 and side cheeks 3 in the form of freely rotating disks (D) with cutting edges 4. Their ends D are interconnected concentrically with respect to axes of rotation 6 of them. Cutting edges D contacting ground located below the cutting edge of the knife. When the blade is deepened and the bulldozer is moved, D is rotated due to contact with the ground. The movement of the layer of soil along the dump coincides in direction with the rotation of D and-st zhk. The prism of the soil is moved by rolling in front of the blade, and on the sides of the blade the formation is cut by edges D, 2 Il.

Claims (2)

Claim 1. Bulldozer equipment, including a blade with a knife and side cheeks, made in the form of freely rotating disks with cutting edges located on the periphery, characterized in that, in order to reduce the energy consumption of the cutting process and the movement of soil, the ends are interconnected by means of concentrically arranged relative to the axes of rotation of the rigid couplers, while the cutting edges of the disks in contact with the soil are located below the cutting edge of the knife blade. 2. Equipment according to claim 1, characterized in that the couplers are made in the form of flexible connections. 1434042 ’
