EXCAVATOR BUCKET Russian patent published in 2022 - IPC E02F3/40 

FIELD: mining industry.

SUBSTANCE: invention relates to the construction and mining industries, namely to single-bucket excavators with working equipment: front shovel and loading equipment, as well as to single-bucket front loaders. The excavator bucket includes a bottom, a visor, hydraulic cylinders for turning the visor mounted from the bottom edge of the bottom with rods up, rods, levers for turning the visor, hinges for attaching the visor to the bottom. The bucket of the excavator contains four single-arm levers for turning the visor: two pressure and two traction ones, mounted in pairs on one transverse axis, fixed rigidly to the bottom by means of stops and bolts, parallel to the rear wall of the bottom. Single-arm pressure and traction levers are installed perpendicular to the transverse axis, in each single-arm lever end hinges connected to the rod are mounted, as well as ball joints with balls in which holes are made to accommodate the ends of the cantilever fingers of the traverse, which consists of a hollow cup with two finger ends rigidly and coaxially fixed to it from two opposite sides with end thrust nuts. Between each pair of single-arm levers, pins are screwed into the transverse axis by thread, on the free ends of which hollow cups of the traverse are put on with the possibility of rotation relative to the axis of the pins, as well as lifting and lowering the traverse along the axis of the pins.

EFFECT: providing the necessary angle of rotation of the bucket relative to the handle, increase in the technological capabilities of the process of digging rock in the face by means of a bucket, as well as preventing breakage of the elements of the hydraulic mechanism from falling large chunks of rock during digging.
