Abstract

The invention relates to a hopper unchoking device. The hopper unchoking device comprises a photoelectric sensor, a control circuit and a blockage removal unit. The photoelectric sensor comprises at least one group of through beam photoelectric sensors including an optical transmitting sensor and an optical receiving sensor. The control circuit is used for judging whether a hopper is blocked or not according to optical signals received from the optical transmitting sensor by the optical receiving sensor so as to determine outputting control signals for starting or stopping the blockage removal unit. The blockage removal unit comprises a motor, at least one transmission chain, at least one pair of sprockets, at least one operation chain and a plurality of scrape plates, wherein the at least one pair of sprockets are mounted at the top and the bottom of the inner side wall of the hopper, the at least one operation chain surrounds the inside and the outside of the hopper and is mounted on the at least one pair of sprockets, the plurality of scrape plates are mounted on the at least one operation chain, an acute angle larger than 0 degree is formed between each scrape plate and the operation chain along the moving direction, and the operation chain in an operating state rotates in the hopper from top to bottom. The hopper unchoking device is capable of automatically detecting and removing blockage of the hopper without human intervention.

Description

technical field [0001] The invention relates to a hopper used by enterprises, factories and mines, in particular to a device for dredging blockage of a hopper. Background technique [0002] In the existing lower hopper, due to the influence of factors such as the water content of the raw material, its own viscosity, and the size of the block, the failure of the hopper to be blocked occurs from time to time. At present, dredging the blockage of the hopper mainly depends on manual dredging. Manual dredging at least exists: the labor intensity of workers is high, the dredging speed is slow, and the working environment is dangerous. [0003] Therefore, need to invent a kind of device of dredging hopper automatically, to solve many problems that manual dredging exists. [0004] In view of the existing problems of manually dredging the blockage of the hopper, the inventor is based on years of rich practical experience and professional knowledge engaged in the design and manufact...
