The utility model provides an ash bucket is arranged in automation under dust remover accident nature deposition state, include: a bucket body has the ash bucket design and bears material level and high material level early warning material level, a dust leg way has and stretches into bucket body inside and advance the ash pipe and stretch out the outside dust discharge pipe of bucket body, it islocated to advance the ash pipe the ash bucket design is born between material level and the high material level early warning material level, dust discharge pipe's the mouth of pipe seals through anone way check valve subassembly. Can judge conveniently that ash hopper of dust collector is in normal condition or abnormal state at the detection mouth. And can be after exceeding the grey bearing capacity of dust remover design storage, after the dust exceeds normal storage ash volume in the ash bucket, make the deposition can arrange the ash voluntarily, realize the protect function to the dust remover from this, simultaneously, when arranging the ash, go back the accessible and touch contact switch, to the relevant control system transmission switch volume signal of telecommunication, realize the acousto -optic warning under the dust remover accident nature deposition state.
