Coal mine electromechanical equipment plays a crucial role in coal mine mining production. They not only improve production efficiency and reduce labor intensity, but also play an irreplaceable role in improving the working environment and reducing safety accidents.

[0003] The utility model of the existing authorized application number CN211777394U discloses a coal mine electromechanical equipment for coal mine mining, including a base.

[0026] The outer surface of the crushing box 7 is fixedly connected to the inner wall of the support frame 2. Two crushing rollers 12 are rotatably connected to the inner wall of the crushing box 7. Two support plates 3 are fixedly connected to the upper surface of the fixed frame 1. The back surface of each support plate 3 is fixedly connected to the front surface of the support frame 2.

[0027] A limiting frame 8 is fixedly connected to the outer surface of the crushing box 7. A second servo motor 16 is fixedly connected to the inner wall of the limiting frame 8. Two rotating shafts 9 are jointly rotatably connected to the inner walls of the two support plates 3. A conveyor belt 10 is jointly rotatably connected to the outer surfaces of the two rotating shafts 9. By setting the rotating shafts 9 and the conveyor belt 10, when the rotating shafts 9 rotate, friction is generated with the conveyor belt 10, and under the action of the friction force, the conveyor belt 10 and the coal on the surface of the conveyor belt 10 can be driven to move.

[0028] The output end of the power of the second servo motor 16 is fixedly connected to a driving shaft 17. The left end of the driving shaft 17 is rotatably connected to the inner wall of the limiting frame 8. A first bevel gear 18 is fixedly connected to the outer surface of the driving shaft 17. The right end of one of the rotating shafts 9 is fixedly connected to a first servo motor 11. The outer surface of the first servo motor 11 is fixedly connected to the right side surface of one of the support plates 3. By setting the first servo motor 11, the power required for conveying can be provided, thus enabling the rapid conveying of coal mines.

The rotation of the second servo motor 16 can drive the drive shaft 17 and the first bevel gear 18 to rotate. Then, under the action of the rotation of the first bevel gear 18, the second bevel gear 19 can be driven to rotate. Subsequently, the rotation of the second bevel gear 19 can drive the first worm gear 20 inside to rotate. The rotation of the first worm gear 20 can drive the second worm gear 21 to rotate. At the same time, since the threads on the surfaces of the first worm gear 20 and the second worm gear 21 are opposite, the first worm gear 20 and the second worm gear 21 can respectively drive the two worm wheels 13 to rotate in different directions. Finally, the crushing roller 12 inside can be driven to crush the coal. The crushed coal falls onto the diversion plate 14 at the bottom of the crushing box 7, and the diversion plate 14 can divert the coal onto the conveyor belt 10. At the same time, the first servo motor 11 can drive a rotating shaft 9 to rotate. Under the rotational friction between the rotating shaft 9 and the conveyor belt 10, the conveyor belt 10 can be driven to rotate, thereby enabling the coal on the surface to be transported.
