[0034] Figures 1-7The second embodiment is shown, and the main difference with the first embodiment is that the outer wall of the two crushing rollers 21 penetrates the outer wall of the crushing box 1, and the second gear 29 is fixedly installed on the outer wall of the two crushing rollers 21, and the two second gears 29 are arranged in meshing with each other, so that the two crushing rollers 21 can rotate in opposite directions. The outer wall of the crushing box 1 is fixedly installed with the first motor 22, the output shaft of the first motor 22 penetrates the inner wall of the crushing box 1, and is fixedly connected with the outer wall of the crushing roller 21. The first motor 22 can drive one of the crushing rollers 21 to rotate. The outer wall of one of the second gears 29 is fixedly installed with the driving wheel 23, and the second gear 29 can drive the driving wheel 23 to rotate when rotating.

[0035] The two groups of crushing rods 28 are arranged in interlaced manner to prevent the crushing rods 28 from colliding. The outer wall of the two rotating rods 27 penetrates the outer wall of the crushing box 1, and the first gear 26 is fixedly installed on the outer wall of the two rotating rods 27. The two first gears 26 are arranged in meshing with each other. The outer wall of one of the two first gears 26 is fixedly installed with the driven wheel 25. The driven wheel 25 and the outer wall of the driving wheel 23 are sleeved with the belt 24. The driving wheel 23 can drive the driven wheel 25 to rotate through the belt 24 when rotating. The driven wheel 25 can further drive the first gear 26 to rotate. The first gear 26 can drive the other first gear 26 to rotate when rotating, so as to drive the two groups of crushing rods 28 to rotate, and the large pieces of raw materials can be crushed, thereby improving the effect of subsequent crushing of the raw materials.

[0036] The top end of the crushing box 1 is fixedly connected with the feeding bin 11. The bottom end of the crushing box 1 is provided with the discharge port 10. The inner wall of the crushing box 1 is fixedly installed with the two guide plates 9. The guide plates 9 can make the crushed raw materials on the top fall between the two crushing rollers 21. The outer wall of the crushing box 1 is fixedly installed with the two vibration motors. The vibration motor is prior art. The vibration motor is arranged on the outer wall of the crushing box 1 adjacent to the filter screen plate 5. When the vibration motor is turned on, the filter screen plate 5 can vibrate, thereby improving the screening rate of the raw materials.

[0037] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0038] When the raw materials need to be crushed, the first motor 22 is started to drive the crushing rollers 21 to rotate. Since the second gears 29 at one end of the crushing rollers 21 are engaged with each other, the two crushing rollers 21 rotate relatively. At the same time, the driving wheels 23 on the second gears 29 drive the driven wheels 25 to rotate through the belts 24. The driven wheels 25 are located on the rotating rods 27, and the crushing rods 28 fixed on the rotating rods 27 also start to rotate. Since the first gears 26 at one end of the two rotating rods 27 are engaged with each other, the two sets of crushing rods 28 rotate relatively. At this time, the materials are poured from the feeding bin 11 into the crushing box 1, and the two sets of crushing rods 28 crush some large pieces of raw materials into small particles, which then fall down. At this time, the crushing rollers 21 are pressed and ground, effectively avoiding the problem that the crushing effect is poor when the large pieces of raw materials are directly crushed by the crushing rollers 21, thereby improving the crushing quality of the raw materials. The crushed raw materials are filtered through the filter screen plate 5 below. The raw material particles that meet the requirements fall from the filter screen plate 5 and then fall from the crushing box 1 through the discharge port 10. The raw material particles that do not meet the requirements are left on the surface of the filter screen plate 5. At the same time, the vibration motor can be started to vibrate the raw materials on the filter screen plate 5, thereby improving the screening effect of the raw materials. When the filter screen plate 5 needs to be replaced, the electric push rod 89 is started to shorten, thereby driving the two beveled edge top blocks 86 to move towards the beveled edge moving plate 85 through the two moving rods 87 and the connecting plate 88. At this time, the beveled edge moving plate 85 is pressed, thereby driving the two clamping plates 84 on the sides to move outward through the slide rod 82, so that the clamping plates 84 are moved away from the clamping grooves in the moving slide 6. At this time, the filter screen plate 5 is not clamped and fixed by the clamping plates 84, so that the filter screen plate 5 can be removed from the crushing box 1. Then, the raw material particles on the filter screen plate 5 can be processed. When a new filter screen plate 5 needs to be replaced, the moving slide 6 on the filter screen plate 5 is aligned with the slide groove 3, and then the filter screen plate 5 is slid and inserted into the inside of the crushing box 1, so that the clamping grooves on the moving slide 6 are aligned with the clamping plates 84. Then, the electric push rod 89 is started to extend, thereby driving the two beveled edge top blocks 86 to move away from the surface of the beveled edge moving plate 85. At this time, the beveled edge moving plate 85 is not pressed, and the clamping plates 84 are clamped into the clamping grooves under the elastic force of the springs 83, thereby completing the fixation of the filter screen plate 5. Through the movement of the beveled edge top blocks 86, the filter screen plate 5 is quickly disassembled and installed, thereby improving the replacement efficiency of the filter screen plate 5 and greatly shortening the replacement time, reducing the equipment downtime, and improving the production efficiency.
