Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The technical solution of the present invention is further described below with reference to the accompanying drawings.

As shown in fig. 1, a pulverizer with a novel structure comprises a casing 1, wherein a hollow pulverizer shaft 3 is arranged at the inner axis of the casing 1, a tubular structure 20 is arranged at the left side of the casing 1, a volute structure 11 communicated with the tubular structure is arranged at the right side of the casing 1, a flange plate 10 is arranged at the inner side of the tubular structure 20, the volute structure 11 is connected with the flange plate 10, a round nut 4 is fixedly connected to the surface of the middle part of the hollow pulverizer shaft 3, the round nut 4 presses a hammer rack 17, a feed inlet 2 is formed in the top end of the tubular structure 20, and a discharge outlet 19 is formed in the lower part of the volute.

One end of the hollow crusher shaft 3 is fixedly connected to the outer side of the tubular structure 20 through a first bearing 6, the right end of the hollow crusher shaft 3 is fixedly connected to the outer side of the spiral case 11 through a second bearing 5, the first bearing 6 and the second bearing 5 are the same in model, the first bearing 6 and the second bearing 5 are both 6308, the 6308 bearing is a large bearing with a large specification, so that the hollow crusher shaft 3 is not deformed due to overweight or overlarge resistance of the hammer rack 17, and the bearing load performance is also prevented from being influenced, thereby greatly improving the practicability of the crusher with the novel structure, ensuring the service life of the crusher with the novel structure, the right end of the hollow crusher shaft 3 penetrates through and extends to the outer part of the casing 1 and is fixedly connected with the belt pulley 9, the hammer rack 17 is sleeved on the hollow crusher shaft 3 positioned in the spiral case 11, the hammer rack 17 is provided with the hammer shaft 18 in the periphery, the hammer shaft 18 is provided with the crusher hammer 16 in a penetrating way, the bran screen 12 is wrapped outside the crusher hammer 16, the number of the crusher hammer 16 is eight, and the eight crusher hammer 16 are sleeved on the hammer shaft 18 at equal intervals.
