BULLDOZER BLADE Russian patent published in 2022 - IPC E02F3/76 E02F3/80 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to municipal, road, agricultural and mining engineering, in particular, to machines for removing snow, bulk and lump materials. Bulldozer blade includes a body with a curvilinear frontal sheet, a metal knife installed on one of the working sides of the body, and a plate made of an elastic material such as rubber is installed on the opposite side. Eyelets, rigidly fixed on the back side of the body, with locking holes for connection with the pushing frame by means of rods. The location of the eyelets provides a possibility of changing the working sides of the blade by a 180° turn. A rod or a sleeve is installed in the body, included in the rotary joint ensuring additional connection of the blade with the pushing frame and turning of the blade for changing the working side. The eyelets are arranged around the axis of rotation of the blade, in an amount of at least two pairs, wherein the locking hole of each eyelet in each pair, when changing the working side of the blade, takes the position of the locking hole of the matching eyelet.
