DEVICE FOR BREAKING BRIDGES OF LOOSE MATERIAL IN HOPPERS

摘要

FIELD: material handling facilities. SUBSTANCE: invention relates to storing loose materials and to devices aimed at preventing formation of hand-ups in process of material discharge from hoppers. Proposed device contains vertical rod with fitted-on bushings mounted for adjusting and fixing in position in height of rod. Flexible working members are made in form of upward curved links whose ends are hinge-connected on bushings and hopper housing. Pins are installed on convex side of flexible working members. Rod has drive imparting reciprocating motion to rod, and providing oscillating motion of flexible working members in vertical. Curvature of working members change in process of rod movement. With all members of device operating, loose material contained in hopper is freely discharged through discharge port outsides. EFFECT: improved reliability in operation. 2 dwg
