AI Technical Summary
When using the unblocking mechanism, the raw coal bunker experiences problems such as jamming, arching, and sticking to the wall. Furthermore, the rotating conical tube is prone to pressure and friction during rotation, which can create gaps and affect the unblocking effect.
A raw coal clearing device for a coal feeder was designed, including a feeding mechanism, a protective unit, and a crushing component. The device uses a geared motor to drive a screw rod for feeding, and combines a scraper and baffles to prevent dust from scattering. The crushing component also prevents clumping. The integrated production process results in better sealing.
It achieves efficient coal dredging, prevents pressure friction on the rotating conical tube, reduces production costs, reduces dust pollution, prevents blockage of the feed inlet and powder from entering the gaps, and improves sealing and dredging efficiency.
