Description

Technical Field

[0001] The utility model relates to the field of equipment related to a hammer crusher, and more specifically, to a blockage clearing device for a hammer crusher. Background Art

[0002] After the ore mining is completed, it is often necessary to crush the ore. When crushing the ore, a hammer crusher is often needed to crush the ore. The ore is broken by the rotation of the crushing hammer, and then the broken ore passes through the screen plate arranged inside the crusher to achieve the crushing and screening of the ore. Since the ore is damp, the screen plate is easily blocked, so a cleaning device is needed to clean the screen plate. The existing cleaning device generally blows off the mineral powder blocked on the screen plate by jetting, etc. Due to the continuous accumulation of mineral powder, the mineral powder cannot be completely blown off by jetting alone, so the cleaning effect of the screen plate is not good, and the existing cleaning device lacks a collection structure. The mineral powder that appears after cleaning will be scattered in the crusher, which is inconvenient to take out, thereby affecting the recovery of the mineral powder, resulting in waste of mineral powder and affecting the use of the entire hammer crusher.
