[0001] The utility model relates to the technical field of coal crushers, in particular to an anti-blocking coal crusher. Background Art

[0002] During coal production and processing, the uniformity and crushing efficiency of coal lumps have a significant impact on the quality of the final product. When processing wet coal lumps, conventional coal crushers are prone to adhesion and clogging in the crushing chamber, leading to unstable equipment operation. Furthermore, single-stage crushing is typically used, which fails to fully crush the coal lumps, resulting in some lumps being too large, affecting subsequent combustion efficiency. Therefore, it is necessary to improve existing coal crushers to address these issues.

[0003] The above information disclosed in this Background section is only for understanding the background of the present inventive concept and therefore it may contain information that does not constitute prior art. Utility Model Content

[0004] The purpose of the present utility model is to provide an anti-blocking coal crusher to solve the problem that when the coal crusher proposed in the above background technology processes coal blocks with high humidity, the coal blocks are easily adhered and blocked in the crushing chamber, resulting in unstable operation of the equipment, and single-stage crushing is usually adopted, which cannot fully crush the coal blocks, resulting in some coal blocks being too large, affecting the subsequent combustion efficiency.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A blockage-resistant coal crusher comprises a fixed frame, a first crushing roller and a first crushing chamber, a feeding channel is fixedly installed on the upper end of the fixed frame, one side of the feeding channel is fixedly connected to the first transmission channel, a first metal conveyor belt is installed inside the first transmission channel, a first servo motor is installed on one side of the first transmission channel, the first servo motor is connected to the first metal conveyor belt, a drying frame is fixedly installed on the upper end of the first transmission channel, a hot air blower is fixedly installed on the upper end of the drying frame, the hot air blower is connected to three air nozzles at the lower end of the drying frame, a first crushing chamber is installed on the upper end of the first transmission channel, a first base is provided on one side of the first crushing chamber, a first drive motor is fixedly installed on the upper end of the first base, and the first drive motor is connected to the first crushing roller inside the first crushing chamber.

[0007] As a preferred technical solution, one side of the first conveying channel is connected to the second conveying channel through a slide, a second metal conveyor belt is installed inside the second conveying channel, a second servo motor is installed on one side of the second conveying channel, and the second servo motor is connected to the second metal conveyor belt inside the second conveying channel.

[0009] As a preferred technical solution, a first rotating baffle is installed on one side of the feeding channel, and a second rotating baffle is installed on the slideway.

[0010] As a preferred technical solution, a controller is installed on the upper end of the first base, and the controller is electrically connected to the first servo motor, the hot air blower, the first drive motor, the second servo motor, and the second drive motor.

[0011] The beneficial effects of the utility model are:

[0012] With this coal crusher, the hot air generated by the hot air blower is blown directly to the wet coal on the conveyor belt through the air nozzle. The drying effect of the hot air reduces the moisture content of the coal blocks, thereby reducing the possibility of coal blocks clogging the conveyor belt due to wet stickiness, improving the fluidity of the coal blocks, making the dried coal blocks easier to crush, and also helping to reduce energy consumption in the subsequent crushing process.

[0013] In addition, the setting of the first crushing chamber and the second crushing chamber forms a multi-stage crushing process. The coal blocks are first sent to the first crushing chamber through the first transmission channel for preliminary crushing, and then transmitted to the second transmission channel through the slide and further crushed in the second crushing chamber. The multi-stage crushing mechanism improves the crushing efficiency and ensures that the coal blocks are fully crushed. At the same time, the precise control of the servo motor ensures the stable operation of the conveyor belt and improves the continuity and uniformity of the entire coal crushing process.
