A first gear 5 is fixedly installed on the outer wall of the first crushing roller 3, and a second gear 6 is fixedly installed on the outer wall of the second crushing roller 4. The second gear 6 meshes with the first gear 5. When the servo motor 2 is started, the output shaft of the servo motor 2 drives the first crushing roller 3 and the first gear 5 to rotate. The rotation of the first gear 5 drives the second gear 6 and the second crushing roller 4 to rotate. The reverse rotation enables the first crushing roller 3 and the second crushing roller 4 to crush the stones. It also includes a conveying assembly installed inside the housing 1, which is used to evenly convey the stones between the first crushing roller 3 and the second crushing roller 4. A transmission assembly is installed between the first crushing roller 3 and the conveying assembly. Through the transmission assembly, the servo motor 2 can also provide power to the conveying assembly. A dust extraction assembly is installed on the rear side of the housing 1. The dust extraction assembly is used to extract dust. A filter screen plate 15 and an inclined plate 16 are fixedly installed on the inner walls of the front and rear sides of the housing 1. The inclined plate 16 is located below the filter screen plate 15.

[0024] Furthermore, the conveying assembly includes a conveying channel 7, a rotating rod 8, and bolt pieces 9.

There are two bolt pieces 9, both fixedly installed on the outer wall of the rotating rod 8, and the two bolt pieces 9 are symmetrically arranged front and rear. This can evenly convey the stones between the first crushing roller 3 and the second crushing roller 4, preventing the stones from accumulating on the first crushing roller 3 and the second crushing roller 4 and preventing the first crushing roller 3 and the second crushing roller 4 from getting stuck.

[0025] Furthermore, the transmission assembly includes a first synchronous pulley 12, a second synchronous pulley 13, and a synchronous belt 14. The first synchronous pulley 12 is fixedly installed on the outer wall of the first crushing roller 3, and the second synchronous pulley 13 is fixedly installed on the outer wall of the rotating rod 8. The synchronous belt 14 is sleeved on the first synchronous pulley 12 and the second synchronous pulley 13, and the synchronous belt 14 meshes with both the first synchronous pulley 12 and the second synchronous pulley 13. When the servo motor 2 is started, the output shaft of the servo motor 2 drives the first crushing roller 3, the first gear 5, and the first synchronous pulley 12 to rotate. The first synchronous pulley 12 drives the second synchronous pulley 13, the rotating rod 8, and the bolt plate 9 to rotate through the synchronous belt 14. The rotation of the bolt plate 9 can transport the stones, driving the stones to fall between the first crushing roller 3 and the second crushing roller 4 through the discharge port 11, providing power for the conveying assembly, realizing two uses in one machine, reducing the number of motors used, and reducing costs.

[0026] Furthermore, the dust extraction assembly includes a dust collection box 20, an exhaust fan 21, an exhaust pipe 22, and an air supply pipe 23.

One end of the air supply pipe 23 is fixedly connected to the output end of the exhaust fan 21. When the air supply pipe 23 is connected to the dust removal equipment, the exhaust fan 21 is started. The exhaust fan 21 extracts air from the inside of the dust collection box 20 through the exhaust pipe 22, so that the dust inside the box body 1 enters the interior of the dust collection box 20 through the dust extraction hole 24. The dust inside the dust collection box 20 is transported to the dust removal equipment through the exhaust pipe 22, the exhaust fan 21, and the air supply pipe 23, preventing dust from spreading around and preventing workers from inhaling dust.

[0027] Furthermore, the top of the conveying channel 7 has two inlets 10, and the bottom of the conveying channel 7 has an outlet 11.

[0028] Furthermore, two guide plates 25 are fixedly installed on the inner walls of the front and rear sides of the box 1. The two guide plates 25 are arranged symmetrically from left to right, and the guide plates 25 are in contact with the outer wall of the conveying channel 7.

[0030] Furthermore, a dust extraction hole 24 is provided on the rear side of the box 1, and four casters 19 are movably installed on the bottom outer wall of the box 1, with foot brakes on the casters 19.

[0031] Working principle: Stones are fed into the housing 1 and enter the conveying channel 7 through the feed inlet 10. Then, the servo motor 2 is started. The output shaft of the servo motor 2 drives the first crushing roller 3, the first gear 5, and the first synchronous pulley 12 to rotate. The first synchronous pulley 12, through the synchronous belt 14, drives the second synchronous pulley 13, the rotating rod 8, and the bolt plate 9 to rotate. The rotation of the bolt plate 9 conveys the stones, causing them to fall through the discharge outlet 11 between the first crushing roller 3 and the second crushing roller 4. Meanwhile, the rotation of the first gear 5 drives the second gear 6 and the second crushing roller 4 to rotate in the opposite direction, ensuring that the first crushing roller 3 and the second crushing roller 4 can... The stones are crushed and then screened through the filter screen 15. The qualified crushed stones fall into the first collection box 17 along the filter screen 15, while some fine fragments fall into the top of the inclined plate 16 through the filter screen 15 and into the second collection box 18 along the inclined plate 16. One end of the air supply pipe 23 is connected to the dust removal equipment, and the exhaust fan 21 is started. The exhaust fan 21 draws air from the inside of the dust collection box 20 through the exhaust pipe 22, so that the dust inside the box 1 enters the inside of the dust collection box 20 through the dust extraction hole 24. The dust inside the dust collection box 20 is transported to the dust removal equipment through the exhaust pipe 22, the exhaust fan 21, and the air supply pipe 23.
