HOPPER FOR BRIDGE-FORMING LOOSE MATERIALS Russian patent published in 2003 - IPC

FIELD: agriculture; production of construction materials. SUBSTANCE: invention relates to method of storage of bridge-forming loose materials. Proposed hopper contains pressure stabilizers hinge-mounted on opposite walls of housing with displacement relative to its vertical axis. Stabilizers are furnished with individual drives to adjust angles of their arrangement relative to walls of housing and are made grid-like. Pressure stabilizer grid cleaning devices are made up of plates hinge-secured outside the housing in places of pressure stabilizer mounting, and rods secured on surfaces of plates and passed through holes in housing walls. Rods are installed for passing through meshes of stabilizer grids in lowered down position. Invention makes it possible to regulated process of hopper filling from bottom to top and provide regulated discharge of material at control of loose material pressure in unloading device.
