[0030] Furthermore, the crushing component is composed of a pressing shaft 14, a gear ring 15 and a gear track 16. Two pressing shafts 14 are arranged and are correspondingly arranged inside the crushing box 5. One end of each pressing shaft 14 extends to the outer end of the crushing box 5 through the inner wall of the crushing box 5 and is respectively fixedly connected with a gear ring 15. The outer end of one gear ring 15 extends and is connected to the output end of the first rotating motor 11. A gear track 16 is fixedly sleeved on the outer ends of the two gear rings 15.

[0031] Furthermore, the two sides of the inner wall of the box body 1 are respectively provided with an inclination degree, and a lead screw 17 is arranged at the center of the upper end inside the box body 1. One end of the lead screw 17 extends to the outer end of the box body 1 through the inner wall of the box body 1 and is fixedly connected with a third rotating motor 13.

The upper ends of the number of buffer springs 21 are fixedly connected to the bottom end surface of the support column 3.

[0034] Working principle: Coal is fed through the feed inlet on the upper surface of the crushing box 5. The connecting plate 6 connected to the feed inlet not only guides the materials but also serves as the support structure for the subsequent atomized dust removal system. Inside the crushing box 5, the first rotating motor 11 is first started to drive the gear ring 15 connected to one end to rotate. Through the meshing action of the gear track 16, the gear ring 15 at the other end and the corresponding extrusion shaft 14 are driven to rotate synchronously. The two extrusion shafts 14 rotate relatively to conduct preliminary physical extrusion and crushing on the coal entering the crushing box. During the crushing process, in order to prevent the dust generated by coal crushing from polluting the environment, the water source in the water tank 8 enters the pressure intensifier 10 through the infusion pipe 9. The pressure intensifier raises the water pressure and sprays it out through the atomizing nozzles inside it to form a fine water mist. These atomizing nozzles extend into the crushing box through the connecting plate 6 to spray the coal during the crushing process, effectively suppressing the flying of dust and achieving the dust removal effect. The relative setting of the atomizing nozzles ensures the uniformity and comprehensiveness of the spraying. The preliminarily crushed coal falls into the box body 1. At this time, the third rotating motor 13 drives the screw rod 17 to rotate, driving the crushing rod 18 fixed on it to rotate and stir inside the box body to further crush the coal, improving the crushing efficiency and quality. The inclined design of the inner wall of the box body helps the coal move downward under the action of gravity and stirring, facilitating subsequent discharging and further processing. The fully crushed coal finally reaches the bottom of the box body 1. At this time, the second rotating motor 12 drives the rotating screw 19 to rotate. The spiral blades of the rotating screw push the coal forward until it is discharged through the opening provided at the bottom of the box body. The design of the discharge plate 4 and the adjustable baffle 7 at the front end of the discharge port facilitates controlling the discharge speed and quantity of the coal to meet different production requirements. The entire coal crusher is fixed on the ground through the base 2 and the support columns 3. The support seat 20 sleeved at the bottom of the support column and the buffer spring 21 inside it effectively absorb the vibration and impact during the operation of the equipment, improving the stability and service life of the equipment.
