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

FIELD: agricultural; 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 hopper installed at an angle to a horizontal surface with the possibility of adjusting its inclination angle, three dampers attached to the body of the hopper with the possibility of adjusting their inclination angle relative to the longitudinal axis of the hopper, rotating rollers mounted on body of the device. The bunker is divided into three sections - upper, middle and lower. The upper section of the hopper has an obtuse angle at the base of its side surfaces, and the middle and lower sections of the hopper have acute angles. The lower section of the hopper has a more acute angle at the base of its side surfaces compared to the middle section of the hopper. The upper, middle and lower sections of the bunker have different volumes of internal cavities. The upper section of the hopper has the largest volume of the internal cavity, and its lower section has the smallest volume.

EFFECT: ensuring a uniform and dosed supply of bulk material.
