The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

Fig. 1 is the structural representation of the utility model beater grinder.Comprise the motor 1, transport portion and the pulverizing part that are arranged on the base plate 13, the driving wheel 2 of motor 1 is connected with the drive 8 of pulverizing part with the follower 10 of transport portion respectively by belt; The follower 10 of transport portion is connected with belt wheel 12 by conveyer belt 11, and the power that follower 10 utilizes driving wheel 2 to transmit drives conveyer belt 11 and rotates around follower 10 and belt wheel 12, and the fines that will sieve from the sieve plate 9 of pulverizing part in time transfers out; Pulverize part and comprise pulverizing chamber 3, pulverizing chamber 3 is horizontally disposed cylindrical cavities, the upper end of pulverizing chamber 3 is provided with charging aperture 5, the lower end of pulverizing chamber 3 is provided with discharging opening, one sieve plate 9 is installed on this discharging opening, rotating shaft 16 is installed in the pulverizing chamber 3 vertically, one end of rotating shaft 16 stretches out pulverizing chamber 3 and fixing with drive 8, as shown in Figure 2, fixed interval has four groups of cutterheads 7 in the rotating shaft 16 in pulverizing chamber 3, four groups of cutterheads 7 connect by the bearing pin 6 that three groups of axial symmetry are provided with, and a hammer leaf 4 is installed on the bearing pin between every group of adjacent cutterhead 76.

As Fig. 2, shown in Figure 3, be the structural representation of the utility model beater grinder cutterhead part and hammer leaf.The pin-and-hole 15 of hammer leaf 4 is sleeved on the bearing pin 6, and the tup that impacts of hammer leaf 4 is cylindrical shapes, and the existing spherical tup of weight ratio is bigger, and the better effects if that material impacts, the hammer leaf 4 that only demonstrates one group of bearing pin 6 among Fig. 2 and install are above faced in impacting that it is straight.
