Description

Technical Field

[0001] The utility model relates to the technical field of coal component detection, in particular to a pulverizing device for coal component detection. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. During the mining process, coal mines need to be sampled and tested continuously to ensure the quality of the coal. Coal mine testing first requires the coal to be crushed, so a corresponding crusher is needed.

[0003] The existing referenceable Chinese utility model patent with announcement number CN218689862U discloses a coal testing pulverizer that avoids powder residue, including: a device body, a pulverizing chamber is arranged inside the device body, a pulverizing roller is arranged inside the pulverizing chamber, and a scraping mechanism is arranged inside the pulverizing chamber; a driven gear, the driven gear is connected to the rear end of the pulverizing roller, the rear end of the driving gear is connected to a motor, and the front end of the driving gear is connected to a transmission gear; an aggregate box, the aggregate box is arranged inside the device body, the front end of the aggregate box is connected to a sealing plate, and the rear end of the aggregate box is connected to a telescopic cylinder, the lower end of the aggregate box is connected to a slider, and the lower end of the slider is provided with a slide rail. The coal testing pulverizer that avoids powder residue solves the problem that powder is easily adhered to the inner wall of the pulverizing chamber when pulverizing coal, which is inconvenient to handle, and dust is easily raised when discharging, causing adverse effects on personnel.

[0004] Existing coal crushing equipment generally crushes materials through two matching crushing rollers. During the crushing process, the coal may fall from the left and right sides of the crushing roller to the bottom of the equipment, affecting the coal crushing effect. In this way, the coal may accumulate above the crushing roller, causing the material to be unable to pass through the crushing roller normally, affecting the crushing efficiency.
