Bridge Breaking Hopper

摘要

The present invention relates to a bridge braking hopper capable of preventing the bridge of raw material stored in the hopper thereof and capable of smoothly discharging the raw material, thereby performing a volumetric conveyance. The bridge braking hopper comprises the hopper, an agitator, and a screw conveyor. The hopper storing the raw material has an agitator, and, especially, has a conveyor installed to be inserted into the bottom thereof without an outlet nozzle. The agitator having a driving motor on the top of the hopper has an agitator shaft at the center thereof. The agitator shaft is rotated for agitation by a chain. The driving motor is positioned on the upper side of the hopper so that the height of the inlet of the hopper can be adjusted to allow an operator to input the raw material stably. The screw conveyor inserted into a conveyor housing on the lower side of the hopper is capable of improving conveyance efficiency by increasing the contact surface of the raw material in the hopper. The screw conveyor capable of being rotated forward and backward is capable of improving the performance of the agitator when rotated backward to input the raw material into the hopper. When storing raw material sensitive to atmospheric humidity, the bridge braking hopper is capable of initially preventing the bridge of the raw material, thereby storing the raw material for a long time regardless of the storage period of the raw material. In addition, the bridge braking hopper allows a user requiring powder material to utilize added functions of the volumetric conveyance and mixing.
