EXCAVATOR BUCKET Russian patent published in 2019 - IPC E02F3/40 

FIELD: construction; mining.

SUBSTANCE: invention relates to construction and mining industries, namely to single-bucket excavators with equipment direct spade and loading equipment, as well as single-bucket front loaders. Excavator bucket includes a bottom, a canopy, hydraulic cylinders of turn of the shield, installed on the side of the lower edge of the bottom with rods upwards, rods, levers of the deflector turn, hinges of attachment of the cap to the bottom. Latter rotation levers are installed on two different axes located parallel to the rear wall of the bottom and perpendicular to its longitudinal axis and fixed in the brackets on the bottom. To each hub of single-arm levers installed on axles, toothed wheels engaged with each other are rigidly and coaxially fixed. Single-arm levers on the bottom lower edge side are hinged to the hydraulic cylinder rods hinges, and the single-arm levers on the upper edge side of the shield are connected to its hinges.

EFFECT: reduced dimensions of hydraulic mechanism of lifting and lowering of shield in order to provide required angle of bucket turn relative to handle, increase of technological capabilities of process of digging of rock in working face by turning bucket, as well as reduced size and gravity of the upper edge of the shield, designed to prevent breakage of hydromechanism opening of the bucket during digging.
