Anti-blocking method for lower coal hopper of boiler coal mill

The anti-blocking method for the lower coal bucket of the boiler coal mill comprises the steps that firstly, raw coal is poured into the bucket body, then a first motor is started to drive a feeding box to move towards the bottom of the bucket body through a threaded rod, a material stopping plate is driven to move away when the feeding box moves, the raw coal in the bucket body falls into the feeding box at the moment, and then the first motor rotates reversely; when the hopper body is blocked, a second motor can be started to drive a main bevel gear and an auxiliary bevel gear through a first rotating shaft to drive a second rotating shaft, and the second rotating shaft drives a stirring rod to stir the raw coal in the hopper body. And in addition, the first rotating shaft synchronously drives a second connecting rod to rotate, the second connecting rod drives a hitting ball to hit the hopper body through a spring, and discharging of the hopper body is smoother. The anti-blocking method is used for the coal
