FIELD: storage of loose materials. SUBSTANCE: invention relates to device designed for preventing formation of bridges in process of discharging loose materials from hoppers of stationary or mobiles storages. Proposed device has rod with at least two concentric conical spirals fitted on. Spirals are wound with different hand of helix and different pitch. Lower ends of spirals are rigidly secured in lower part of rod, while upper ends are connected with rod by means of bushing adjustable in height and locked in position. Rod has vibratory or rotational drive. Device provides breaking the bridges, separating and loosening the material by acting onto monolith by coils of spiral. EFFECT: increased velocity of material flowing out and reduced time taken for unloading. 1 dwg
