The materials in the bin 1 begin to fall into a material storage area 3 in the drawing box 2. Electromagnetic braking ware 5 gets the signal this moment, electromagnetic braking ware 5's pivot lock can not rotate, then driving motor 6 drives pull box 2 and pull board 4 integrative removal simultaneously, driving motor 6 antiport then, through first rack 16, second rack 15, electromagnetic braking ware 5, first connecting plate 7, second connecting plate 8, drive pull box 2 and the synchronous same speed of pull board 4 and move to the discharge gate 11 of discharge box 9, when pull box 2 reaches the 11 terminal surfaces of discharge gate of discharge box 9, according to the predetermined settlement, stock district 3 communicates with discharge gate 11. At this moment, the ejection of compact mode has two kinds, one kind is electromagnetic braking ware 5 can not signal, electromagnetic braking ware 5's pivot is not locked the rotatable, driving motor 6 continues to rotate, only drives pull board 4 forward motion, promotes the material forward motion in the material storage area 13 in the pull box 2, transports to discharge gate 11 from feed inlet 10, begins the ejection of compact, when pull board 4 occupies the volume in the material storage area 13 in the pull box 2 completely, the material ejection of compact is ended, accomplishes the ejection of compact action. The other discharging mode is that the electromagnetic brake 5 obtains a signal, a rotating shaft of the electromagnetic brake 5 is locked and does not rotate, the driving motor 6 continues to drive the drawing box 2 and the drawing plate 4 to synchronously move at the same speed, so that the material storage area 3 moves towards the discharging port 11 with the volume unchanged, the material is completely moved out, and the discharging action is completed.
