Description
Technical Field
[0001] This utility model relates to the field of coal mine crushing, and in particular to a coal mine crusher with a dust collection structure. Background Technology
[0002] Coal mine crushers are indispensable key equipment in coal mining and processing. Their main function is to crush large chunks of raw coal to a particle size suitable for subsequent washing, transportation, or use. These machines typically use two counter-rotating crushing rollers to compress and crush the material, driven by a motor and with gears ensuring synchronous operation. The crushing operation takes place inside a closed frame, and the crushed coal is discharged through the outlet at the bottom. The efficiency of the crushing process, the stability of the equipment operation, and its adaptability to materials directly affect the smoothness and efficiency of the entire coal production process. Therefore, efficient and reliable coal mine crushing equipment is of great significance for improving the production efficiency and safety of the coal industry.
[0003] However, existing coal mine crushers generally face a severe challenge during operation—dust pollution. When high-speed rotating crushing rollers apply enormous compressive force to hard coal blocks, a large amount of fine coal dust particles are inevitably generated. This dust not only permeates the working environment around the equipment, severely deteriorating working conditions and posing a direct threat to the respiratory health of operators, but long-term exposure also increases the risk of occupational diseases. Therefore, a coal mine crusher with a dust collection structure has been proposed. Utility Model Content

The two connecting pipes communicate with the inner cavities of the two grooves respectively. By setting up the dust extraction assembly in conjunction with the air extraction assembly, the dust generated during the coal mine crushing process is extracted to prevent its diffusion.
[0008] Furthermore, the air extraction assembly includes an air extraction pipe, a dust extraction frame, an air extraction fan, and a protective net. The air extraction pipe is fixed to the lower side of the connecting pipe and is connected to the air extraction pipe. Two corresponding dust extraction frames are fixed to the left and right sides of the mounting frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This coal mine crusher with a dust collection structure has the following advantages: 1. The dust collection system of this equipment creates negative pressure in the crushing area using an exhaust fan to actively extract dust particles. After being adsorbed by the guide and barrier plates, the dust eventually falls into the storage tank, thus preventing dust from spreading into the operating environment. This mechanism significantly reduces air pollution and lowers the health risks (such as respiratory diseases) of operators from long-term dust exposure, while improving workplace visibility and comfort. Compared with existing technologies, this design achieves efficient dust control without the need for additional ventilation equipment, demonstrating the equipment's advantages in safety and environmental protection. 2. The storage components feature a sliding design, with guide wheels and a handle system allowing the storage box to be easily pulled out of the connecting frame for material cleaning or dust removal. This design simplifies daily maintenance procedures, reduces equipment downtime, and avoids the cumbersome operation of disassembly required by traditional fixed storage structures. Operators can quickly access the storage area using only the handle, improving equipment availability and overall production efficiency. This feature ensures continuous operation and long-term reliability of the equipment, especially in high-frequency operations such as coal mine crushing. Attached Figure Description
