Description

[0002] In the prior art, the arch breaking mechanism of the hopper is mostly a vibration machine directly installed on the outer wall of the hopper, which directly drives the hopper wall to vibrate to break the arch. Since the hopper wall is a fixed plate, the vibration amplitude is small, so the arch breaking effect is poor. On the other hand, since the entire hopper wall participates in the vibration, the noise is large, and the hopper wall is prone to fatigue cracking due to long-term vibration.

[0003] To overcome the above problems, the utility model with patent No. 202121581349.0, named "anti-clogging powder feeding device", provides an improved scheme: a gas pump is arranged on the feeding hopper, a plurality of jet ports for communicating with the gas pump are arranged on the inclined plate, and the plurality of jet ports are evenly arranged along the direction perpendicular to the axis of the feeding hopper. The powder is fed into the feeding port of the feeding hopper, and the jet ports on the inclined plate are evenly arranged at the discharge port of the feeding hopper, so that the powder in each corner of the discharge port can move under the action of the gas flow, thereby reducing the probability of accumulation and blockage of the powder during the discharging process.
