It should be noted that, the diameter of the discharging barrel 321 is larger than that of the auger conveying channel, so that the discharging barrel 321 is ensured to have a larger inner cavity, and the materials can flow out conveniently.

In the actual use process, the weighing mechanism 330 is arranged below the discharge hole of the discharge cylinder 321, so that the materials discharged from the discharge hole can be weighed in real time, and the weight is accurately controlled.
