[0020] In this embodiment, the cement to be crushed is firstly passed through the feed port 7 into the crushing box 9, and then the crushing roller 8 is driven by the transmission mechanism to rotate and crush. The crushed cement passes through the second filter screen 19 and then through the discharge port 20 to reach the inside of the receiving box 21. The dust generated by the cement crushing is sucked into the inside of the dust removal box 17 through the dust removal mechanism, and then filtered through the first filter screen 12, thereby effectively avoiding the problem of pollution caused by the generation of a large amount of dust. The generated dust not only harms the working environment and the health of the staff, but also pollutes the surrounding environment, thereby reducing the limitations of the device. After the filtering is completed, the first filter screen 12 can be conveniently replaced through the limiting mechanism, thereby increasing the practicality of the device.

[0021] Among them, the limiting mechanism includes a slider 31, which is slidably connected to the inside of the slide groove 23, a first spring 24 is fixedly connected between the top of the slider 31 and the inner wall of the slide groove 23, a clamping block 30 is fixedly connected to the bottom of the slider 31, a clamping groove 29 is opened inside the mounting frame 18, and the bottom of the clamping block 30 extends to the inside of the clamping groove 29.

[0022] Among them, the limiting mechanism also includes a resistance rod 25, which is slidably connected to the inside of the dust removal box 17, and one end of the resistance rod 25 is fixedly connected to a pressing block 26. A second spring 27 is sleeved on the outer side of the resistance rod 25, and the two ends of the second spring 27 are respectively fixedly connected to one side of the dust removal box 17 and one side of the pressing block 26. A groove 28 is provided on one side of the clamping block 30, and one end of the resistance rod 25 is in conflict with one side of the groove 28.

[0023] The bottom of the block 30 is provided with an inclined surface. When the first filter 12 needs to be replaced, the pressing block 26 is pressed to drive the abutment rod 25 to move and compress the second spring 27, so that the abutment rod 25 abuts the groove 28 to drive the block 30 to move and disengage the block 30 from the inside of the groove 29, and then the handle 13 is pulled to drive the mounting frame 18 to disengage from the inside of the dust removal box 17, thereby completing the replacement of the first filter 12. In this way, the first filter 12 can be replaced more conveniently and quickly, so that the filtering effect of the device is always in an effective state, thereby increasing the practicality of the device.

[0024] The transmission mechanism includes a fixed frame 4, which is fixedly connected to one side of the crushing box 9. A driving motor 3 is fixedly installed inside the fixed frame 4. One end of the output shaft of the driving motor 3 is fixedly connected to a driving gear 6. One side of the crushing box 9 is rotatably connected to a driven gear 5. The driven gear 5 is meshed with the driving gear 6. One side of the driven gear 5 is fixedly connected to one end of the crushing roller 8. When crushing, the driving gear 6 is driven to rotate by the output shaft of the driving motor 3, and the driven gear 5 is driven to rotate at the same time, thereby driving the crushing roller 8 to rotate to perform the crushing work. Since the ratio of the driving gear 6 to the driven gear 5 is one to two, the crushing efficiency is increased, thereby increasing the crushing effect of the device.

[0025] The dust removal mechanism includes a dust inlet 10, which is fixedly connected to the inside of the crushing box 9, one end of which extends to the inside of the shipping dust removal box 17 and is fixedly connected to the dust outlet 11, a suction fan 14 is fixedly installed on the top of the bottom plate 1, and an air inlet 15 is fixedly connected to the inside of the dust removal box 17, and one end of the air inlet 15 is fixedly connected to one end of the suction fan 14. The suction fan 14 sucks air, driving the dust inside the crushing box 9 through the dust inlet 10 and then through the dust outlet 11 to reach the inside of the dust removal box 17 for filtration, thereby increasing the dust removal effect of the device.

[0026] A controller 22 is fixedly mounted on the top of the base plate 1 , and the driving motor 3 and the suction fan 14 are both electrically connected to the controller 22 .

[0027] Working principle: First, the cement to be crushed is fed into the crushing box 9 through the feed port 7. Then, when crushing, the output shaft of the driving motor 3 drives the driving gear 6 to rotate and drives the driven gear 5 to rotate, thereby driving the crushing roller 8 to rotate for crushing. Since the ratio of the driving gear 6 to the driven gear 5 is one to two, the crushing efficiency is increased. Then, the air is sucked by the suction fan 14 to drive the dust inside the crushing box 9 through the dust inlet 10 and then through the dust outlet 11 to reach the inside of the dust removal box 17 for filtration. Finally, when the first filter 12 needs to be replaced, the pressing block 26 is pressed to drive the resistance rod 25 to move and compress the second spring 27 at the same time, so that the resistance rod 25 resists the groove 28 to drive the block 30 to move and make the block 30 disengage from the inside of the groove 29. Then, the handle 13 is pulled to drive the mounting frame 18 to disengage from the inside of the dust removal box 17, thereby completing the replacement of the first filter 12. In this way, the first filter 12 can be replaced more conveniently and quickly, so that the filtering effect of the device is always in an effective state, thereby increasing the practicality of the device.
