[0029] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the outer wall of the large gear 13 is meshed with the small gear 12, the outer wall of the rotating rod 2 is fixedly connected with a fixed shaft 14, the top of the fixed shaft 14 is fixedly connected with a fixed frame 15, a motor 16 is provided inside the fixed frame 15, the output end of the motor 16 is fixedly connected to the top of the rotating rod 2, the outer wall of the rotating rod 2 is fixedly connected with a conical tooth 17, the interior of the crushing tank 3 is fixedly connected with a support plate 18, the interior of the support plate 18 is provided with an annular groove 19, the interior of the annular groove 19 is slidably connected with a sliding column 20, the top of the sliding column 20 is fixedly connected with a crushing roller 21, the interior of the crushing roller 21 is provided with a card slot 22, the interior of the card slot 22 is slidably connected to the outer wall of the card block 11, and the material of the conical tooth 17 is alloy steel.

[0031] The following is a detailed description of the working principle of the coal crushing device.

[0032] like Figure 1-4 As shown, when the coal needs to be crushed, the user starts the motor 16, and the output end of the motor 16 drives the rotating rod 2 to rotate. When the rotating rod 2 rotates, the large gear 13 on its outer wall rotates accordingly. Since the large gear 13 is meshed with the small gear 12, and the small gear 12 is meshed with the ring gear 8, the ring gear 8 can be adjusted in position under the control of the electric push rod 6 through the connecting block 7, thereby driving the small gear 12 to rotate, and the conical teeth 17 on the rotating rod 2 rotate with the rotating rod 2. When the coal enters the crushing pot 3, the conical teeth 17 exert a force on the crushing roller 21 connected to the top of the slide post 20. Since the crushing roller 21 is slidably connected to the block 11 of the rotating rod 2 through the slot 22, and the slide post 20 can slide in the annular groove 19 of the support plate 18, the crushing roller 21 can rotate around the rotating rod 2 under the action of the conical teeth 17, thereby generating a strong impact force and shear force on the coal, thereby achieving coal crushing;

[0033] When the crushing assembly needs to be repaired, the user starts the electric push rod 6. The telescopic end of the electric push rod 6 will push the connecting block 7 and the crushing assembly to rise inside the slide groove 9 through the sliding frame 10. At the same time, the rotating rod 2 will drive the clamping block 11 to slide inside the clamping groove 22. When the crushing assembly rises to the required height, the staff can carry out maintenance work on a certain component without having to remove a large number of surrounding components first, which improves flexibility.

[0034] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
