Description

Technical Field

[0001] The utility model relates to the technical field of discharge hopper cleaning devices, in particular to an automatic water spraying cleaning device for a discharge hopper of a stacker / reclaimer. Background Art

[0002] When the port stacker-reclaimer performs stacking operations, the unloading belt sends the ore to be stacked into the unloading funnel. The ore to be stacked falls onto the adjusted mixing plate and rebounds to the center of the cantilever belt below the inclined funnel, and then is transported to the top of the material pile through the cantilever belt.

[0003] During the stacker-reclaimer unloading process, the material and humidity of the material affect the angle at which it enters the discharge hopper. Therefore, the angle of the grading plate needs to be adjusted for different materials. When unloading materials with high humidity or mass, the grading plate is typically adjusted at a larger angle to ensure smooth passage of the material onto the center of the conveyor belt. This slows the flow of material to be unloaded, causing it to accumulate in the corners of the inclined hopper below. Furthermore, the excessively large adjustment plate angle reduces the discharge opening of the inclined hopper, which can easily lead to blockage. Unloaded material begins to accumulate in the inclined hopper and ultimately accumulates in the upper discharge hopper. Overfilled material can leak through gaps such as under the belt rollers, reducing the stacking efficiency of the stacker-reclaimer, damaging the discharge conveyor, and impacting the structures near the discharge opening and the safety of on-site workers.
