Weight sensing automatic control discharging device

The utility model relates to a weight sensing automatic control discharging device which is characterized in that a storage bin, a conveying pipe and a metering hopper are fixed to a supporting frame, the storage bin is communicated with the conveying pipe through a discharging pipe, auxiliary materials needing to be added are temporarily stored in the storage bin, and when the device is used, a material scattering assembly can be driven by a telescopic rod to move up and down to stir the auxiliary materials in the storage bin, so that the auxiliary materials in the storage bin can be scattered; meanwhile, the auxiliary materials at the position of the discharging pipe are dredged, and the auxiliary materials at the position of the discharging pipe are prevented from being blocked in the discharging process; auxiliary materials in the storage bin can enter the conveying pipe through the discharging pipe, the driving motor is used for driving the spiral auger to rotate so that the auxiliary materials can be co
