Technical Field

[0001] The utility model relates to the technical field of hopper arch breaking of large-scale destruction equipment, in particular to a hopper arch breaking device based on PLC control. Background Art

[0002] Most of the existing large-scale destruction equipment has a two-stage crushing structure. After coarse crushing by the pre-crushing tool, the medium is crushed into fine pieces by the crushing tool. The two-stage cutters are connected by a hopper. The hopper structure is wide at the top and narrow at the bottom. Due to reasons such as structural size, the interval between the two-stage cutters cannot be too large. The slope of the hopper is gentle, which can easily cause bridging and blockage at the outlet. It requires manpower to clear or repair it, which seriously affects the discharge and the crushing efficiency. Utility Model Content
