An air intake port 92 is provided at the right end of the air pump 91, and an exhaust port 93 is provided at the left end of the air pump 91.

[0025] The specific implementation process of this utility model is as follows: When in use, the specific working process of the pellet mill has been disclosed in the utility model patent with patent authorization announcement number CN207996641U, and will not be repeated here.

[0026] When feeding through the feed inlet 4, the motor 88 works simultaneously. The output end of the motor 88 drives the cam 82 to rotate, which in turn drives the hinge rod 83 to rotate. The hinge rod 83 pushes the hinge seat 84 to move, and the hinge seat 84 can drive the guide block 86 to slide along the guide groove 87. This allows the push rod 85 to move back and forth in the vertical direction. The push rod 85 can push the material inside the feed inlet 4 into the crushing box 3, which can accelerate the feeding efficiency, avoid material blockage, and help improve the overall working efficiency of the equipment.

[0027] During the crushing process in the crushing chamber 3, the air pump 91 operates simultaneously. The air pump 91 draws air from the inside of the dust collection chamber 5 through the air extraction port 92, creating a negative pressure inside the dust collection chamber 5. Then, it draws air from the outside through the fixed pipe 96, causing the air inlet 98 to draw air from the feed inlet 4. This allows the dust and debris particles generated during the crushing process to be drawn into the dust collection chamber 5 along with the air through the air inlet 98. Subsequently, the dust particles are filtered and purified by the filter plate 94, and the impurities are retained on the surface of the filter plate 94. Finally, the gas is discharged from the inside of the dust collection chamber 5 through the exhaust port 93, which can effectively prevent the spillage of dust during cutting from polluting the external environment.
