d. when air pump (15) worked, pneumatic cylinder (54) work, do reciprocating motion at the horizontal direction through pneumatic cylinder (54) flexible drive driving movable toothed plate (51) for gear (55) rotate, under the effect of air duct (19 a), make violently pipe (18) and branch pipe (19) swing, thereby can stir the material in hopper body (2), further be favorable to the ejection of compact of material, further improve device's ejection of compact efficiency.
