BULLDOZER EQUIPMENT Russian patent published in 2022 - IPC E02F3/76 

FIELD: road construction equipment.

SUBSTANCE: invention relates to road construction equipment, in particular to earth-moving vehicles. A sharpening device bracket and a displacement hydraulic cylinder are welded to the support. Anti-friction plates are placed inside the support. A knife is placed inside the anti-friction plates. The knife has two transverse slots on top. Inside the support are two blade hydraulic cylinders with springs and hollow rods. The hollow rods and the knife are connected by collet joints. A leash is welded to each knife hydraulic cylinder. The other ends of the leads are welded to the rods. The rods enter the displacement hydraulic cylinder. A piston with a shock absorber is attached to each rod. Two levers are attached to the sharpener bracket. They are rigidly attached to the hydraulic motor. Two multipliers with abrasive wheels on the output shafts are attached to the hydraulic motor. The hydraulic cylinder of the grinding device with a handle is also pivotally attached to the hydraulic motor. The hydraulic cylinder of the grinding device rests on the hydraulic cylinder brackets. The hydraulic cylinder brackets are welded to the blade. Satellite dishes are installed on the dump. In the tractor cab there are: a display, a control and signaling unit, a repair control unit. The repair control unit communicates with the remote control. The equipment of the bulldozer is equipped with: a knife fixation sensor, a knife penetration rate sensor, an activation sensor, a sharpening device hydraulic cylinder rod extension sensor, a knife profilogram sensor.

EFFECT: reduction of energy costs for the operation of the unit and its operation.
