Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-Figure 3 In the embodiment of the utility model, a coal gangue sorting device includes a sorting box 1, a driving motor 2 for providing power for the rotation of a sorting conveyor belt 3 is installed on one side outer wall of the sorting box 1 through a support frame, a sorting conveyor belt 3 for sorting materials is arranged in the inner cavity of the sorting box 1, and a vibration mechanism 4 is arranged on the sorting box 1;

[0031] The vibration mechanism 4 includes a transmission unit and a vibration unit;

[0032] The transmission unit is used to synchronously drive multiple sorting conveyor belts 3;

[0033] The vibration unit is used to intermittently give vibration force to the sorting conveyor belt 3;

[0034] The transmission unit includes a rotating rod 401, a rotating wheel 402, a transmission rod 403, and a stop block 404;

[0035] The rotating rod 401 is rotatably installed in the inner cavity of the sorting box 1 and meshes with the inner cavity of the sorting conveyor belt 3. The rotating rod 401 is used to drive the sorting conveyor belt 3 to transmit;

[0036] The rotating wheel 402 is fixed to one end of the rotating rod 401, and the rotating wheel 402 is used to synchronously drive one end of the transmission rod 403 to move in a circumferential direction;

[0037] The transmission rod 403 is eccentrically rotatably connected to the outer wall of the rotating wheel 402, and the transmission rod 403 is used to synchronously drive the multiple rotating wheels 402 to rotate;

[0038] The stopper 404 is fixed to the outer wall of the rotating rod 401, and the stopper 404 is used to apply a squeezing force to the movable rod 405 during the rotation process;

[0039] The vibration unit includes a movable rod 405, a striking rod 406, a positioning rod 407, and a spring 408;

[0040] The movable rod 405 is vertically slidably installed in the inner cavity of the sorting box 1, and the movable rod 405 is used to drive the striking rod 406 to move synchronously;

[0041] The striking rod 406 is fixed to the outer wall of the movable rod 405 and extends to the bottom of the sorting conveyor belt 3. The striking rod 406 is used to intermittently give vibration force to the sorting conveyor belt 3;

[0042] The positioning rod 407 is fixed to the inner cavity of the sorting conveyor belt 3, and the positioning rod 407 is used to provide guidance for the vertical movement of the movable rod 405;

[0043] Two ends of the spring 408 are respectively clamped on the inner wall of the sorting box 1 and the outer wall of the movable rod 405 , and the spring 408 is used to provide a restoring elastic force for the movable rod 405 to move.

[0044] In this embodiment: through this structure, when the material is poured into the sorting box 1, the material will fall on the sorting conveyor belt 3 on the uppermost layer. By starting the driving motor 2, the driving motor 2 will drive the rotating rod 401 to rotate, and the rotating rotating rod 401 will synchronously drive the sorting conveyor belt 3 to transmit, so as to transport the material. The transported material will fall through the gap between the sorting conveyor belts 3 and contact with the sorting conveyor belt 3 of the next layer. The sorting conveyor belts 3 with different lengths make the sorted materials fall into the collection boxes at different positions, completing the sorting operation of the materials.

[0045] During the rotation of the rotating rod 401, the rotating wheel 402 will be synchronously driven to rotate. The rotating rotating wheel 402 will synchronously drive one end of the transmission rod 403 connected to the eccentric rotation of the outer wall to rotate. The transmission rod 403 rotating at one end will rotate around the axis of the rotating wheel 402, thereby driving the other rotating wheels 402 to rotate, thereby synchronously driving multiple sorting conveyor belts 3 to transport materials. During the rotation of the rotating rod 401, the block 404 fixed on the outer wall will be synchronously driven to rotate clockwise. The block 404 rotating clockwise will contact the protruding force block on the outer wall of the movable rod 405, thereby giving the movable rod 405 a thrust to move upward. 05 is forced to move upward along the outer wall of the positioning rod 407 and give the spring 408 an extrusion force. The striking rod 406 will also move with the movement of the movable rod 405, so that the end of the striking rod 406 is separated from the top of the sorting conveyor belt 3 until the circumferentially rotating stop block 404 is no longer in contact with the outer wall force block of the movable rod 405. At this time, the movable rod 405 will be reset under the elastic force of the spring 408, and the striking rod 406 hits the upper surface of the sorting conveyor belt 3 under the action of the spring 408, so that the sorting conveyor belt 3 vibrates, and the intermittent and uninterrupted striking makes the materials stuck in the gap of the sorting conveyor belt 3 fall down, avoiding material jamming and further improving the work efficiency.

[0046] Please refer to Figure 1-Figure 3 There are multiple striking rods 406, which are evenly distributed on the outer wall of the movable rod 405. The outer wall of the striking rod 406 is in an "L"-shaped structure as a whole. The bottom end of the striking rod 406 is rotatably connected to a roller at a position where it contacts the top of the sorting conveyor belt 3. The inner cavity of the sorting box 1 is formed with a slide groove for the movable rod 405 to move vertically. The cross-section of the slide groove is in a "convex"-shaped structure. A force-bearing block is fixed to the outer wall of the movable rod 405, and the position of the force-bearing block coincides with the rotation trajectory of the stop block 404.

[0047] In this embodiment: through this structure, when the stop block 404 is not in contact with the outer wall force block of the movable rod 405, the bottom end of the striking rod 406 will contact the upper surface of the sorting conveyor belt 3, and the continuously transmitted sorting conveyor belt 3 will contact the roller at the bottom end of the striking rod 406, thereby reducing the friction between the striking rod 406 and the sorting conveyor belt 3.
