The first crushing wheel 3 is close to the second crushing wheel 31, and a gap is left between them. The second crushing wheel 31 is rotatably provided on the other side of the upper part of the crushing box 2. The first crushing wheel 3 and the second crushing wheel 31 are used to crush the raw materials. The ends of the first and second crushing wheels 31 extend out of the crushing box 2, and the protruding parts of the two are respectively provided with a first gear 4 and a second gear 41. The first gear 4 and the second gear 41 are used for transmission, and the first gear 4 is far away from the second gear 41. The third gear 5 and the fourth gear 51 are rotated and arranged in meshing relationship with each other on the outer side of the upper part of the crushing box 2. The third gear 5 and the fourth gear 51 are staggeredly meshed with the first gear 4 and the second gear 41. The third gear 5 is staggeredly meshed with the first gear 4 above, and the fourth gear 51 is staggeredly meshed with the second gear 41 above. A mounting plate 6 is provided on the outer side of the upper part of the crushing box 2, and a first motor 7 is provided on the mounting plate 6. The first motor 7 is used to drive the crushing wheels at two locations to rotate. The output shaft of the first motor 7 is connected to the fourth gear 51. A shaking screen group for shaking is provided at the lower part of the crushing box 2.

[0022] like Figures 1-5As shown, the shaking screen group includes a guide rod 8, a coarse filter 9, a fine filter 10, a transmission shaft 11, a shaft cover 12, a cam 13 and a second motor 14. Guide rods 8 are slidably provided on both sides of the inside of the crushing box 2 and pass through the lower part thereof. The guide rods 8 serve as guide components for driving the coarse filter 9 and the fine filter 10 to move. A coarse filter 9 and a fine filter 10 are respectively provided between the upper and lower parts of the guide rods 8 on both sides. The coarse filter 9 and the fine filter 10 are used to screen the raw materials. The coarse filter 9 and the fine filter 10 are staggered and tilted to achieve subsequent directional discharging, and the lower parts of the coarse filter 9 and the fine filter 10 correspond to the outlets on both sides of the crushing box 2 respectively, and the raw materials on the two are discharged from the outlets. The lower part of the crushing box 2 is provided with a plurality of guide rods 8 passing through the guide rods 8 at both ends. A transmission shaft 11 passes through the interior thereof, and a shaft cover 12 is provided at the lower part of the crushing box 2.

Both cams 13 are in rotational contact with the corresponding guide rod 8 above. A second motor 14 is provided on the outer side of the bracket 1. The output shaft of the second motor 14 is connected to the transmission shaft 11. The contact between the cam 13 and the guide rod 8 causes the guide rod 8 to vibrate up and down. This vibration is transmitted to the coarse filter 9 and the fine filter 10, causing the coarse filter 9 and the fine filter 10 to vibrate. The larger particles of material are blocked and flow out of the crushing box 2 along the direction of its inclination, while the smaller particles of material pass through the coarse filter 9 and fall into the fine filter 10 below.

[0023] like Figure 5 As shown, it also includes a receiving plate 15, an elastic member 16 and a resisting bar 17. Two groups of receiving plates 15 are staggered on both sides of the interior of the crushing box 2. The receiving plates 15 are supporting components of the buffer combination. One group of receiving plates 15 is provided on both sides of the upper part of the crushing box 2, and another group of receiving plates 15 are provided on both sides of the lower part of the crushing box 2. The upper receiving plate 15 corresponds to the bottom of the coarse filter 9 and is inclined at the same angle as the coarse filter 9. The lower receiving plate 15 corresponds to the bottom of the fine filter 10 and is inclined at the same angle as the fine filter 10. In the inclined state of degrees, each receiving plate 15 is provided with an elastic member 16 at the bottom, and a stop bar 17 is slidably provided on the upper part of each receiving plate 15. The stop bar 17 is connected to the corresponding elastic member 16. The upper stop bar 17 is in sliding contact with the coarse filter 9, and the lower stop bar 17 is in sliding contact with the fine filter 10. During the screening process, the elastic member 16 and the stop bar 17 play an auxiliary role. Through the contact between the stop bar 17 and the filter screen, the residence time of the material on the filter screen is increased, thereby improving the screening efficiency.

[0024] When the raw material needs to be crushed, first, the raw material enters the inside of the crushing box 2 through the cone hopper 21 on the top of the crushing box 2, the cone hopper 21 enables the raw material to be evenly distributed between the first crushing wheel 3 and the second crushing wheel 31 in the crushing box 2, at this time, the first motor 7 starts to work to drive the fourth gear 51 to rotate, since the fourth gear 51 is engaged with the third gear 5, the third gear 5 also starts to rotate, since the third gear 5 is engaged with the first gear 4 in a staggered manner, the first gear 4 also rotates with the third gear 5, similarly, the fourth gear 51 is engaged with the second gear 41 in a staggered manner, so that the second gear 41 also rotates with the fourth gear 51, in this way, it can be ensured that the raw material is subjected to uniform extrusion and shearing force when entering the crushing area, so that a more uniform crushing process is realized, the first crushing wheel 3 and the second crushing wheel 31 start to rotate in a state of approaching each other, with the rotation of the first crushing wheel 3 and the second crushing wheel 31, the raw material entering the crushing box 2 will be subjected to extrusion and shearing action in the gap between the two crushing wheels, the crushed raw material continues to fall downward and enters the next screening process, the crushed raw material continues to move downward and is screened through the coarse filter screen 9 and the fine filter screen 10, at this time, the second motor 14 starts to work to drive the transmission shaft 11 to rotate, the cam 13 on the transmission shaft 11 rotates with it, the cam 13 is in contact with the guide rod 8, so that the guide rod 8 slides up and down to realize the vibration process, the vibration is transmitted to the coarse filter screen 9 and the fine filter screen 10, so that the larger particle materials above the coarse filter screen 9 and the fine filter screen 10 are blocked and flow out of the crushing box 2 along the inclined direction thereof, while the smaller particles fall into the fine filter screen 10 below through the coarse filter screen 9, similarly, under the action of the fine filter screen 10, finer particles continue to fall downward, while the larger particles flow out of the crushing box 2 along the inclined direction thereof, in this process, the elastic member 16 and the blocking strip 17 play an auxiliary role, through the contact between the blocking strip 17 and the filter screen, the residence time of the material on the filter screen is increased, and the screening efficiency is improved, at the same time, the elastic member 16 can absorb the impact force caused by vibration to protect the equipment from being damaged.
