Fig. 1 shows the partial schematic diagram according to the rabbling mechanism of prior art;
Fig. 2 shows the partial schematic diagram according to the rabbling mechanism of embodiment of the present utility model; And
Fig. 3 shows the partial schematic diagram according to the guide cylinder of the rabbling mechanism of embodiment of the present utility model.
The specific embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.It should be noted that, in the situation that do not conflict, embodiment and the feature in embodiment in the application can combine mutually.
As shown in Figures 2 and 3, according to embodiment of the present utility model, provide a kind of rabbling mechanism, comprised spice cylinder 10, guide cylinder 20 and feed hopper 30.Wherein spice cylinder 10 can rotate around himself axis, spice cylinder 10 has the first charging aperture, guide cylinder 20 is fixed in spice cylinder 10, guide cylinder 20 has the second charging aperture, the second charging aperture is connected with the first charging aperture, and the discharge port of feed hopper 30 stretches in the second charging aperture of guide cylinder 20, makes guide cylinder 20 have the part barrel jacket to be located on feed hopper 30, have gap between the internal perisporium of the periphery wall of feed hopper 30 and guide cylinder 20, this gap is generally 5 to 20 millimeters.This part cylindrical shell be set on feed hopper 30 of guide cylinder 20 has the material of leakage return port 21.
Leak material return port 21 and there is the effect that prevents that the interior material of spice cylinder 10 from flowing out.When rabbling mechanism tilts, material can from spice cylinder 10 interior to flow, flow into the gap between feed hopper 30 and guide cylinder 20, when return port 21 is expected in Flow of Goods and Materials to leakage, material can expect that from leaking return port 21 throws away to the inwall of spice cylinder 10 along with the rotation of spice cylinder 10, thereby prevent that material from dropping down onto road surface from the outflow of the gap between feed hopper 30 and guide cylinder 20 and polluting, also avoid the generation of material loss wasting phenomenon.
Preferably, due to guide cylinder 20, along with spice cylinder 10 rotates, so leak material return port 21, have a plurality ofly, and a plurality of leakage material return port 21 circumferential directions along guide cylinder 20, can more fully prevent that material from flowing out.
