HOPPER FOR LOOSE MATERIAL Russian patent published in 1995 - IPC

FIELD: storage and discharging of loose materials. SUBSTANCE: hopper for loose material has housing, sectional funnel with neck, metering system with gate, divider arranged inside hopper; additional dividers are made in form of dihedral angle members arranged over perimeter of sectional funnel. Bases of members lie on inner surfaces of funnel and housing, respectively. To create critical values of stress concentration in loose material, hopper is furnished with weakening members secured on inner surface of housing and cutting member; inner surface of hollow gate and outer surface of sectional funnel are provided with strain gauges coupled with gate control system to regulate pressure and discharge of loose material. Weakening members are made in form of parallel guides inclined relative to horizontal plane to provide gravity slipping of loose material towards sectional funnel. Guides are arranged uniformly above dividers and are fastened on inner surface of housing. Weakening members can be made in form of triangular cross-section prisms fastened in inner surface of housing in parallel with horizontal plane to form two opposite rows, vertically displaced relative to each other so that upper and lower faces of two vertically displaced opposite prisms are arranged in plane of slipping towards sectional funnel to cut blocks inside loose material. Cutting member is located on inner perimeter of housing for translation coordinated with gate control system and strain gauges. Cutting member has additional blades of similar shape arranged perpendicularly relative to each other and rigidly secured in edges of cutting member and at point of their relative intersection. Cutting part of blades has concave saw shape. EFFECT: enlarged operating capabilities. 5 cl, 9 dwg
