Detailed ways

Below in conjunction with specific embodiment the utility model is further described.

Embodiment 1: A kind of crusher, as shown in Figure 1-4, comprises frame 1, and described frame lower end is provided with wheel 17, and frame front end is provided with traction frame 18, adopts wheel type, traction frame to move, The required space is small and the working place is flexible. The frame 1 is provided with a motor 2, a feeding device, a crushing device and a discharging device, the feeding device is arranged on the upper part of the crushing device, and the discharging device is arranged on the lower part of the crushing device; the feeding device includes a feed bin 3, The lower part of the silo is provided with a feed conveyor roller 4 and a feed conveyor belt 5, the feed conveyor belt is driven by the feed conveyor roller, and the material in the feed bin 3 falls onto the feed conveyor belt 5, and the feed conveyor belt 5. The end is connected with the crushing device, and the material is sent to the crushing device; the crushing device includes a receiving hopper 6, and a sprayer 19 is arranged on the receiving hopper, and the raw materials to be crushed in the silo 3 are evenly sent to the crushing device through the feeding conveyor belt 5 In the receiving hopper 6 of the machine, at the same time, the sprayer 19 sprays and removes dust on the material.
