DEVICE FOR UNLOADING LUMPY MATERIAL FROM HOPPER Russian patent published in 2021 - IPC B65G65/40 

FIELD: material unloading.

SUBSTANCE: invention relates to a device for unloading lumpy material. The device for unloading lumpy material from the hopper contains a working body, a nozzle. The body is located at an angle of 60° to the horizontal, made in the form of a plate and fixed to the end and vertical walls from the inner side of the hopper. The nozzle is fixed on the outer side of the end wall of the hopper with the possibility of turning and fixing and is made in the form of a trapezoidal box with a spool and elastic V-shaped nozzles located on the side of the smaller base. The attachments are made with longitudinal grooves and are installed in the grooves of the end wall of the hopper. The body is equipped with movable and fixed plates, complete with rods with drives. The rods are laid across the bottom in cylindrical kinematic pairs. The pairs are fixed on a fixed plate from the outside of the device together with the front wall, passed through the coaxial holes of the front wall and the fixed plate, and are fixed from the outside to the movable plate. Drives for moving rods with travel limitation are made in the form of hydraulic cylinders and are installed in cylindrical guides on a fixed plate, fixed to it by one ends using cylindrical hinges, and by other ends are hingedly connected through lugs with cylindrical hinges. The hinges are fixed to the movable plate. Rods and hydraulic cylinders are located symmetrically with respect to the axes of symmetry of the fixed plate.

EFFECT: increased efficiency of unloading lumpy material from the hopper.
