DEVICE FOR LOOSE MATERIAL SUPPLY Russian patent published in 2021 - IPC B07B1/46 B07B1/14 

FIELD: technological processes.

SUBSTANCE: disclosed invention relates to dosing equipment and can be used for supply of various loose materials in agricultural, forestry, seeding equipment for their separation into fractions. Bulk material feed device comprises a triangular hopper configured to adjust its inclination angle, rotary rollers mounted on the body, feeding and adjustable flaps configured to adjust their inclination angles, wherein the opening degree of the supply flap provides a certain gap between the supply flap and the bottom of the triangular hopper, which creates a flow of loose material. Adjustable dampers are made with possibility of their convergent-divergence angle changing. Gaps between adjustable shutters determine shape and speed of loose material supply to rotary rollers of the device. Bulk material is fed in uniform volume due to distribution of pressure in equal extent on adjustable dampers.

EFFECT: increased uniformity of bulk material supply to working element.
