[0029] Auxiliary metering and discharging process of metering and batching equipment for cement production:
[0030] The operator opens the valve on the surface of the discharge pipe 9, collects the cement flowing out from the end of the discharge pipe 9 through an external container, and at the same time connects the external power supply of the second motor 301, starts the output shaft of the second motor 301 to rotate and drive the connecting rod 303 to rotate, and the connecting rod 303 drives the shaft rod 304 and the second bent rod 305 to rotate, and the second bent rod 305 stirs at the bottom of the discharge pipe to speed up the cement discharge, thereby completing the auxiliary metering and discharging process of the metering and batching equipment for cement production.
