Description

TECHNICAL FIELD

[0001] The utility model relates to a dredging equipment technical field more specifically, relate to a spiral unblocking device. BACKGROUND

[0002] The current various types of mine concentrators all are provided with ore storage bins for adjusting production flow, distributing ore dressing path, adjusting ore dressing quantity and balancing ore dressing process. The ore bin types can be divided into: square cone funnel bin, V groove type connected bin and cylindrical flat bottom bin. When the ore enters the bin, due to different physical factors such as moisture content, granularity and surface properties of the ore, the friction between the ore and the bin wall increases, so that the ore cannot overcome the frictional resistance under the action of its own gravity and slide out of the bin, causing material sticking and blocking. In addition, due to high moisture content and fine granularity of the material, the sum of particle surfaces in unit volume is large, so the cohesion increases, forming an arched shed material, and a large amount of material stored in the bin wall cannot overcome the internal friction and be discharged outside the bin. When it is slight, it forms a well-shaped shed material, and when it is serious, the material cannot flow in the bin and forms a blockage, completely losing the function of the bin. The current unblocking method is: workers open a material poking hole on the bin wall to poke material, or insert an iron rod into the bin to poke material, or use explosives to blast and dredge, which may cause personal injury and bin damage.
