BULK MATERIAL FEEDER Russian patent published in 2023 - IPC B07B1/46 

FIELD: agricultural and forestry equipment.

SUBSTANCE: dosing equipment used to supply various bulk materials in agricultural, forestry and seed processing equipment in order to separate them into fractions. Device for supplying bulk material contains a housing, a triangular hopper installed at an angle to a horizontal surface with the possibility of adjusting its inclination angle, three triangular dampers attached to the body of the triangular hopper with the possibility of adjusting their inclination angle relative to the longitudinal axis of the triangular hopper, rotating rollers mounted on body of the device. The triangular hopper is additionally provided with a flat inclined surface and is divided into three sections having different angles of inclination and arranged in steps: a section for forming a flow of particles of bulk material, a section for dispersing particles of bulk material and a section for supplying particles of bulk material to a flat inclined surface. The section for dispersing loose material particles has a larger angle of inclination than the section for forming a flow of loose material particles and the section for supplying loose material particles to a flat inclined surface, which makes it possible to evenly distribute bulk material on a flat inclined surface and feed it to rotating rollers.

EFFECT: avoiding the accumulation of bulk material and increasing the uniformity of its supply to the rotating rollers of the device.
