DEVICE FOR REMOVING ACCUMULATED MATERIALS OF HOPPER BY DETECTION OF ACCUMULATED ORES

摘要

PURPOSE: A removing device of accumulated materials is provided to remove the accumulation of materials by detecting the accumulated state of the materials and using a flexible blowoff wall. CONSTITUTION: A moving portion prevents materials(100) by installing in the upper part of a hopper to load materials and moving within a certain range while alternating the part of a blowoff wall. A detecting portion(300) detects the accumulation of the materials by the self-weight of the fallen materials and moves the moving portion by a hydraulic cylinder within the certain range. A connecting portion(400) discharges the materials to detect the accumulation from the self-weight. Thereby, the accumulated ores in a hopper are removed. Moreover, an unloader is used effectively.
