HYDRAULIC BULLDOZER WORKING EQUIPMENT Russian patent published in 2018 - IPC E02F3/40 

FIELD: machine building.

SUBSTANCE: use in earth-moving and loading and unloading operations, including with piece cargo, for unloading construction materials, cleaning debris, garbage. Concept of the invention is as follows: on tractor 1, a gripping device is fixed, resting on the working equipment of the bulldozer, consisting of bulldozer blade 2, pushing bars 3, brace 4, cylinder 5, and including rotating bucket 6, a handle with hydraulic motor 7, a hydraulic cylinder for controlling gripping device 8, gripping jaws 9, hook-like eyelet 10, gripping tooth 11, brackets 12 and removable bucket 13. Hydraulic motor is connected to rotating bucket 6 by means of bushings with bearings. Rigid connection of handle 7 to the hydraulic motor is carried out using a U-shaped frame and a clamp. Lifting and lowering of the gripping device is carried out with the help of hydraulic control cylinder 8 fixed in lower bracket 12, and its rod is fixed in the handle eye with hydraulic motor 7. Removable bucket 13 is attached to gripping jaw 9 by means of hook-like lug 10.

EFFECT: increase in the reliability of the structure in comparison with the prototype due to the attachment of the gripping device to the base tractor, as a result of which the control cylinders are outside the working area; Moreover, the prism of the ground drawing increases when the working equipment is equipped with a removable bucket.
