[0029] Among them, the horizontal feeding cylinder 31 is communicated with the discharge port of the storage cylinder 2; the blanking cylinder 35 is placed at the blanking port 14 and communicated with the horizontal feeding cylinder 31; the first auger blade 33 and the second auger blade 34 are both wound around the conveying shaft 32 and placed in the horizontal feeding cylinder 31 together with the conveying shaft 32; the driving structure 36 is connected to the conveying shaft and used to drive the conveying shaft 32 to rotate; the axis of the blanking cylinder 35 is vertically arranged, one side of which is communicated with the horizontal feeding cylinder 31, the conveying shaft 32 passes through the blanking cylinder 35, and a bearing 341 for arranging the conveying shaft 32 is arranged on the opposite side. As Figure 2 shown, the number of turns of the second auger blade 34 is greater than one turn and less than two turns, the first auger blade 33 and the second auger blade 34 are wound alternately, and the first auger blade 33 and the second auger blade 34 are placed in the horizontal feeding cylinder 31 and one end is placed at the connection with the blanking cylinder 35.

[0030] The weighing cylinder 4 is placed below the blanking cylinder 35 and connected to the top plate 12 through the fixed bracket 41, and a weighing sensor is arranged between the weighing cylinder 4 and the fixed bracket 41.
