[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3 A coal gangue crushing device includes a crushing box 1, a crushing assembly 2 inside the crushing box 1, a feed inlet at the top of the crushing box 1, and a guide slope 101 fixedly installed near the feed inlet inside the crushing box 1 to assist in guiding coal gangue into the crushing box 1. A crushing assembly 3 is installed at the top of the crushing box 1, including a frame plate 301 fixedly installed at the top of the frame plate 301, and a telescopic rod 302 fixedly installed at the top of the frame plate 301. The movable end of the telescopic rod 302 movably passes through the frame plate 301 and is fixedly connected to a hammer 303. The telescopic rod 302 can control the movement of the hammer 303, thereby enabling the crushing of larger pieces of coal gangue.

[0026] Please see Figure 1-4 The crushing assembly 2 is located below the guide slope 101. The crushing assembly 2 includes two crushing rods 201 rotatably mounted inside the crushing box 1. Several blades 202 are evenly distributed around the crushing rods 201, and the blades 202 on the two crushing rods 201 are staggered. Two meshing gears 203 are rotatably mounted on one side of the crushing box 1, which enables the two crushing rods 201 to rotate in opposite directions. The two gears 203 are fixedly connected to the two crushing rods 201 respectively. A motor 204 that drives one of the crushing rods 201 to rotate is fixedly mounted on the other side of the crushing box 1. A receiving plate that is fixedly connected to the motor 204 is fixedly mounted on the other side of the crushing box 1.

[0027] Please see Figure 2-3A vibrating screen assembly 4 is located below the crushing component 2 inside the crushing box 1. The vibrating screen assembly 4 includes a movable frame 401 slidably disposed inside the crushing box 1, and a filter screen 402 slidably disposed inside the movable frame 401 for easy replacement of the filter screen 402. A rotating rod 403 is rotatably disposed inside the crushing box 1, and the rotating rod 403 is located below the movable frame 401. Two cams 404 are fixedly sleeved on the rotating rod 403, and the two cams 404 push the movable frame 401. The distance from the center of the cams 404 to their circumferences is different, so that the movable frame 401 can move up and down when the cams 404 rotate.

[0028] Please see Figure 3 The vibrating screen assembly 4 and the crushing assembly 2 are connected by a synchronous belt 5. One end of the rotating rod 403 rotates through the other side of the crushing box 1, and one end of one of the crushing rods 201 rotates through the other side of the crushing box 1. Synchronous pulleys are fixedly fitted on both the rotating rod 403 and one of the crushing rods 201. The synchronous belt 5 drives the two synchronous pulleys to rotate simultaneously, so that both the rotating rod 403 and one of the crushing rods 201 can rotate.

[0029] Please see Figure 1-3 A collection box 6 is placed inside the crushing box 1. An opening is provided on one side of the crushing box 1 for the collection box 6 to move through. A baffle 601 is fixedly provided on one side of the collection box 6 to close the opening. A groove is provided on one side of the baffle 601. The moving frame 401 slides up and down inside the crushing box 1 and slides to the opening.

[0030] The working principle of this utility model:

[0031] When coal gangue needs to be processed, it can be fed into the crushing box 1. The coal gangue will be lowered to the hammer 303 via the guide slope 101. By activating the telescopic rod 302, the hammer 303 can be moved up and down, thus striking and crushing larger pieces of coal gangue. The coal gangue inside the crushing box 1 will be crushed by the crushing rods 201 and blades 202. By activating the motor 204, one of the crushing rods 201 can be rotated. Since the two gears 203 are meshed, the two crushing rods 201 can rotate in opposite directions, thus crushing the coal gangue. The crushing process allows the crushed coal gangue to enter the filter screen 402. Because the synchronous belt 5 connects two synchronous pulleys, the rotating rod 403 also rotates, which drives the cam 404 to rotate around the rotating rod 403. This causes the moving frame 401 to move up and down inside the crushing box 1, so that qualified coal gangue can be screened into the collection box 6. Unqualified coal gangue will vibrate when the moving frame 401 moves up and down, and will continue to be crushed by the blade 202. After all the coal gangue has been crushed, the telescopic rod 302 and the motor 204 are closed, and then the collection box 6 can be removed from the crushing box 1 by manually pulling the pull chute.

[0032] If the filter screen 402 needs to be replaced, the moving frame 401 and the filter screen 402 need to be moved to the opening, and then the filter screen 402 can be slid out and replaced.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
