DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a conveying device for coal mining includes a conveyor belt 1 and a crushing cover 2, wherein a conveying roller 8 is sleeved in the conveyor belt 1, and two driving shafts 3 are rotatably sleeved in the crushing cover 2, and crushing rollers 4 are fixedly sleeved on the outer walls of the two driving shafts 3. A filter box 11 and an exhaust fan 16 are fixedly arranged on the upper end of the crushing cover 2, a filter screen 12 is slidably sleeved in the filter box 11, and an air outlet pipe 13 is fixedly connected between the filter box 11 and the input end of the exhaust fan 16, and an air inlet cover 14 is fixedly connected to the end of the crushing cover 2 away from the conveyor belt 1, and an air guide pipe 15 is fixedly sleeved in the air outlet of the air inlet cover 14, and the other end of the air guide pipe 15 is fixedly sleeved on the filter box 11.

[0023] In this embodiment, a plurality of supporting legs 6 are fixedly connected to the lower end surface of the side plate of the conveyor belt 1, wherein a mounting plate 7 is fixedly connected between two supporting legs 6, and the crushing cover 2 is fixedly installed on the side of the unloading end of the conveyor belt 1 by bolts penetrating the mounting plate 7, so that the crushing cover 2 can be easily disassembled and assembled as needed.

[0024] In this embodiment, the front ends of the two driving shafts 3 penetrate the crushing cover 2 and are fixedly sleeved with gears 5. The two gears 5 mesh with each other. The rotation of the two meshing gears 5 can drive the two crushing rollers 4 to rotate relative to each other.

[0025] In this embodiment, a synchronous wheel 9 is fixedly sleeved on the same end of one of the driving shafts 3 and the conveying roller 8, and a synchronous belt 10 is sleeved on the outer walls of the two synchronous wheels 9, and the synchronous belt 10 is respectively engaged with the two synchronous wheels 9. The two synchronous wheels 9 are driven to rotate by the synchronous belt 10, so that the driving shaft 3 can be driven to rotate when the conveying roller 8 rotates.

[0026] In this embodiment, a motor is fixedly installed on the outer wall of the side plate of the conveyor belt 1, and the output end of the motor is fixedly connected to one end of the rotating shaft fixedly sleeved on the inner end of the conveyor roller 8, and the conveyor roller 8 is driven to rotate by the motor.

[0027] In this embodiment, a handle is fixedly connected to the upper end of the filter screen 12, and the air inlet of the air outlet duct 13 and the air outlet of the air guide duct 15 are respectively arranged at the front and rear positions of the filter screen 12. The air guide duct 15 sends the dust-laden airflow into one side of the filter screen 12 for filtration, and then the air outlet duct 13 discharges the clean airflow.

[0028] In this embodiment, the opening of the air inlet hood 14 is arranged at a horizontal position above the crushing roller 4 to facilitate the entry of dust, and the air inlet hood 14 is made of a conical structure to prevent coal from accidentally entering and being retained in the air inlet hood 14. A sealing door is rotatably connected to one side of the filter box 11 to facilitate opening the filter box 11 for centralized cleaning of the internal dust.

[0029] It should be noted that the utility model is a conveying device for coal mining. When in use, the conveying roller 8 is driven by a motor to rotate, thereby driving the conveyor belt 1 to transport the coal. After the coal moves to one end of the crushing cover 2 and falls, the synchronous belt 10 is used to drive the two synchronous wheels 9 to rotate, so that the conveying roller 8 can drive one of the drive shafts 3 to rotate, and then the meshing relationship between the two gears 5 is used to make the two crushing rollers 4 rotate relatively to crush the fallen coal. At the same time, the exhaust fan 16 is started to extract the gas in the filter box 11 through the air outlet pipe 13, so that the dust generated by the crushing can enter the air duct 15 through the air inlet cover 14, and enter the filter box 11 to be filtered through the filter screen 12 and then discharged, thereby reducing dust pollution.
