3, after material enters grinding chamber, repeatedly ground by the abrasive wheel that is provided with the helical form grinding groove of taper, the powder process fineness is high, output is large.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the present utility model.
The specific embodiment
Embodiment:
With reference to accompanying drawing, Wood grinder described in the utility model comprises frame 1 and the main frame that is fixedly mounted on the frame 1.Described main frame comprises grinding chamber 4, be located at the selection by winnowing chamber 10 of grinding chamber 4 tops, main motor 17 and wind disembarks.Described grinding chamber 4 is fixed on the frame 1, and its inside is provided with rotor 19, evenly is fixed with several lower coating blades 2 on the outer wall of rotor 19.Described main motor 17 is fixed on the frame 1, and the power input device of its PTO and rotor is in transmission connection by belt 18.The sidewall of described selection by winnowing chamber 10 is provided with charging aperture 3.Described wind is disembarked and is fixedly mounted on the top of selection by winnowing chamber 10, comprise wind disembark motor 11, by wind the disembark impeller 13 and be provided with the collecting bin of discharging opening 12 of wind that motor 11 drives of disembarking.
Be provided with lapping device on the described rotor 19.Described lapping device comprises that the lower steel ring 16 that is fixed on rotor 19 tops, the upper steel ring 14 that is located at lower steel ring 16 tops and several are clipped in the abrasive wheel 15 between lower steel ring 16 and the upper steel ring 14, evenly are fixed with several upper blades 5 on the outer wall of described lower steel ring 16.The end face of described lower steel ring 16 is provided with cannelure, and described each abrasive wheel 15 is evenly distributed in the cannelure.Described abrasive wheel 15 is tapered, and its conical surface is provided with spiral helicine grinding groove.Described upper steel ring 14 is truncated conical shape, and the conical surface of its bottom and the conical surface of described abrasive wheel 15 are complementary.
