8. The automatic discharging device according to claim 6 or 7, wherein: a valve is arranged at the discharge port of the discharging mechanism, and the discharging or stopping of the discharging mechanism is realized through the opening or closing of the valve;
the discharging device also comprises a linkage control mechanism; the linkage control mechanism comprises a driving device and a driving rod driven by the driving device to move up and down, the driving device is electrically connected with the control circuit, and the driving rod is upwards matched with a valve at a discharge port in the blanking mechanism and used for opening and closing the valve; the driving rod is downwards matched with a discharge door of a bearing device in the weighing mechanism and is used for opening and closing the discharge door;
the driving rod has the following three working positions:
when the driving rod is in the middle working position, the driving rod does not act on the valve or the discharge door, so that the valve and the discharge door are kept in a closed state;
when the driving rod is positioned at the upper part, the driving rod acts on the valve to force the valve to be opened downwards, powder in the blanking mechanism falls into the weighing mechanism, and the valve is in an open state and the discharge door is kept in a closed state;
and when the driving rod is positioned at the lower part, the driving rod acts on the discharging door to force the discharging door to be opened downwards, powder in the bearing device falls out of the bearing device, and the valve is kept in a closed state and the discharging door is in an opened state.
