The specific embodiment

Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is elaborated, with further understanding the purpose of this utility model, scheme and effect, but not as the restriction to the utility model claims protection domain.

Please refer to Fig. 1～Fig. 3, the pulverizer that the utility model provides comprises: main box 1, drive unit 7, electric appliance control box 9, organize cutter combination 2 more; Described cutter combination 2 is installed in the main box 1, many group cutters combination 2 is installed on the main shaft 4 according to certain rules, realization chopping effect, this main shaft 4 runs through described main box 1 to be installed, edge is furnished with bearing 12 to support this main shaft 4 on the end wall of this main box 1, for preventing that dressing chopped from dropping and can not be shredded from the neutral of 1 of cutter and main box, fill up diagonal cleat piece 3 be installed at the neutral place that two cutters on same main shaft and main box sidewall form; This main shaft 4 is divided into driven shaft and driving shaft, the many groups of each cover cutter combination on driven shaft and the driving shaft, and each is organized cutter and is combined to form the interspersed spread pattern that interlaces.Driving shaft is by the output shaft of a shaft coupling 6 connection drive units 7, and this driving shaft drives driven shafts by travelling gear 5 and rotates.Above-mentioned drive unit 7 and main box 1 all are installed in the top of electrical equipment 9, and the place, corresponding main box 1 bottom of this electric appliance control box 9 is provided with discharging opening 11, also is provided with control button 8 on this electrical equipment control body.Above-mentioned drive unit is motor and decelerator, and the output shaft of decelerator connects the driving shaft of main shaft 4 by shaft coupling 6.On above-mentioned main shaft, also be provided with axle sleeve and guiding grate.

Please refer to Fig. 4, show the structure that one six cutter that cutter is constituted makes up, as Fig. 4, this cutter combination comprises cutterhead 13 and cutter 14, cutter 14 is fixed on the cutterhead 13 by trip bolt 15, cutterhead 14 be shaped as regular hexagon, install one on the limit cutter, every cutter can independently load and unload; The cutter combination is sleeved on the main shaft by the mode of key location, can be for convenience detach.The physical dimension of cutter 14 can be selected according to the difference of processed raw material material.Certainly the shape of cutterhead is not limited in hexagon, but five regular polygons that the limit is above, the concrete shape of cutterhead is determined the needs of number according to mounting cutter, as Fig. 5 and Fig. 6, show respectively one five cutter and eight the cutter of cutter combination embodiment, install five when needs and be cutter, cutterhead be shaped as regular pentagon, when needs install eight during cutter, cutterhead be shaped as octagon.Those skilled in the art can select cutter that number and cutterhead shape are arbitrarily formed the cutter combination as required, the cutter combining structure that the utility model adopts, its cutter also can be replaced cutter hardness according to handled material, the difference of cutting angle and changing flexibly, make it can handle the raw material of unlike material by changing the cutter mode, enlarge the range of application of pulverizer, realize the economy of machine and combining of practicality.
