A discharge port is provided at the lower end of the drying box 7 on the side away from the feed hopper 72. The drying plate 71 is set with an inclined structure with the end near the discharge port facing downwards. This realizes the crushing, dust removal and filtration of iron ore in the crusher body 4, realizing dust removal and filtration cleaning, making the filtration and dust removal smooth and effective. Moreover, the cleaned material on the filter surface falls directly into the crusher body 4, which is convenient to handle. The clean air discharged from the filtration and dust removal is used for large-area and even air supply and drying of iron ore, which is energy-saving and environmentally friendly.

[0023] Specifically, the crushing mechanism includes a servo motor 5, a connecting shaft 51, a crushing rod 52, and a crushing blade 53. The servo motor 5 is located on the top of the crusher body 4. The output end of the servo motor 5 is connected to one end of the connecting shaft 51 inside the crusher body 4 via a coupling. The crushing rod 52 is located inside the crusher body 4 above the screen 42. The other end of the connecting shaft 51 is connected to the crushing rod 52. The crushing blade 53 is located on the crushing rod 52. The connecting shaft 51 is equipped with a dust removal and anti-clogging mechanism. The servo motor 5 drives the connecting shaft 51 and the crushing rod 52 to rotate continuously inside the crusher body 4, and the crushing blade 53 on the crushing rod 52 is used to crush the iron ore.

[0024] Furthermore, the dust removal and anti-clogging mechanism includes a scraper 54 and a brush 55. A scraper 54 is provided on one side of the connecting shaft 51, and a brush 55 is provided on the top of the scraper 54. The rotation of the connecting shaft 51 drives the scraper 54 and the brush 55 to rotate below the dust removal filter screen 21. The scraper 54 and the brush 55 scrape the powder on the filter surface of the dust removal filter screen 21 and drop it into the crusher body 4. The bottom height of the scraper 54 is higher than the top height of the feed inlet on the crusher body 4. The operation of the scraper 54 does not affect the normal feeding of the feed inlet on the crusher body 4.

[0025] Furthermore, the bottom of the dust filter screen 21 is set to be lower than the height of the top inner surface of the crusher body 4, the top of the brush 55 is set to contact the filter surface of the dust filter screen 21, and the bottom of the brush 55 does not contact the top inner surface of the crusher body 4, so the brush 55 will not cause wear on the top inner surface of the crusher body 4.

[0026] Furthermore, the dust hood 2 is designed with a trumpet-shaped structure with a large bottom opening, and the dust filter 21 is designed with a circular structure, giving the dust hood 2 a large dust removal surface.

[0027] Furthermore, the air supply mechanism includes an air supply box 8, an air inlet 81, an air outlet 82, a first air guide plate 83, and a second air guide plate 84. The air supply box 8 is located at the top of the drying chamber 7 on one side of the hopper 72. An air inlet 81 is located at the end of the air supply box 8 furthest from the hopper 72. The air inlet 81 is connected to the output end of the dust collector fan 3 via an exhaust pipe 6. An air outlet 82 facing the drying plate 71 is located at the bottom of the air supply box 8. The interior of the air supply box 8 is equipped with… The first air guide plate 83 and the second air guide plate 84 are provided on the top of the air supply box 8. The dust-removed and filtered air is delivered to the air supply box 8 through the dust removal pipe 1 and the exhaust pipe 6 from the air inlet 81. The air in the air supply box 8 is concentrated and guided by the trumpet-shaped first air guide plate 83, and the air is guided downward by the second air guide plate 84. The dust-removed and filtered air in the air supply box 8 is guided to flow from the air outlet 82 to the drying plate 71 for drying.

[0028] Furthermore, the No. 1 air guide plate 83 is designed with a large opening on the windward side in a trumpet shape. The No. 1 air guide plate 83 guides the air through the air supply box 8 by changing its diameter, so that the air flow passing through the No. 1 air guide plate 83 is concentrated to form a concentrated airflow. The concentrated airflow has enhanced fluidity and gradually disperses during its flow. The air is continuously concentrated and dispersed in the air supply box 8, so that the air can circulate throughout the entire air supply space in the air supply box 8.

[0029] The usage method of this embodiment is as follows: Iron ore enters the crusher body 4 through the feed hopper 41 via the feed inlet. The servo motor 5 drives the connecting shaft 51 and the crushing rod 52 to rotate continuously inside the crusher body 4. The crushing blades 53 on the crushing rod 52 crush the iron ore. The crushed iron ore is then screened by the screen 42. During the crushing process, the dust removal fan 3 is activated. Under the action of the dust removal fan 3, the air inside the crusher body 4 passes through the dust removal filter 21 and is discharged from the dust removal hood 2. The rotation of the connecting shaft 51 drives the scraper 54 and the brush 55 to rotate below the dust removal filter 21, realizing the function of dust removal and filtration cleaning. This ensures smooth and effective filtration and dust removal, and the cleaned material falls directly into the crusher body 4 for easy processing. A negative pressure is formed inside the crusher body 4, and external air enters the crusher body 4 through the feed hopper 41 via the feed inlet. An airflow is formed inside the feed hopper 41 and the feed inlet, flowing into the crusher body 4. This prevents the dust from overflowing and spreading outwards from the feed inlet and feed hopper 41 during the crushing process. The dust-filtered air is delivered to the air supply box 8 through the air inlet 81 via the dust removal pipe 1 and the exhaust pipe 6. The air is concentrated and guided by the first funnel-shaped air guide plate 83 in the air supply box 8, and then guided downwards by the second air guide plate 84. The dust-filtered air flows from the air outlet 82 to the drying plate 71 in the air supply box 8. The iron ore enters the drying box 7 from the feed hopper 72 and falls onto the drying plate 71. The air outlet 82 delivers air to the iron ore on the drying plate 71 for drying. The clean air discharged from the dust removal filter is used for large-area and even air delivery drying of the iron ore, which is energy-saving and environmentally friendly.
