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.

[0031] See also Figure 1-6The utility model provides a technical solution: a discharging anti-blocking structure for crushed graphite material, comprising: a crushing box 1; an arc-shaped filter screen 2 is located at the bottom of the crushing box 1; two swing arms 3 are provided, and are rotatably installed on both sides of the crushing box 1 respectively; an anti-blocking roller 4 is rotatably installed between the bottoms of the two swing arms 3; a gear bar 5 is arranged along the bottom surface of the arc-shaped filter screen 2; a first gear 6 is arranged on the anti-blocking roller 4, and can be meshed and connected with the gear bar 5; a driving component 7 is arranged on the crushing box 1, and is used to drive the swing arm 3 to drive the anti-blocking roller 4 to move along the bottom surface of the arc-shaped filter screen 2. When the crusher crushes the graphite, the swing arm 3 is driven by the driving component 7 to drive the anti-blocking roller 4 to move back and forth on the bottom surface of the arc-shaped filter screen 2. At the same time, the first gear 6 on the anti-blocking roller 4 cooperates with the gear bar 5 to rotate during the movement of the anti-blocking roller 4, so as to realize the anti-blocking operation of the mesh of the arc-shaped filter screen 2 by the anti-blocking roller 4, so as to avoid the blockage of the screen or the screen plate.

[0032] Specifically, the driving assembly 7 includes a mounting frame 7-1 arranged on the crushing box 1, and a forward and reverse motor 7-2 is provided on the mounting frame 7-1. A rotating rod 7-3 is provided at the driving end of the forward and reverse motor 7-2, and two first transmission rollers 7-4 are provided on the side wall of the rotating rod 7-3. Two second transmission rollers 7-5 are provided at the rotating end of the swing arm 3. The first transmission roller 7-4 and the second transmission roller 7-5 are connected by belt transmission. When in use, the forward and reverse motor 7-2 is started to drive the rotating rod 7-3 to drive the two first transmission rollers 7-4 to rotate, and the two first transmission rollers 7-4 drive the two second transmission rollers 7-5 and the two swing arms 3 to rotate, so as to realize the simultaneous driving of the two swing arms 3 to drive the anti-blocking roller 4 to rotate.

[0033] Specifically, the anti-blocking roller 4 includes a connecting roller 4-1 rotatably installed between the bottoms of the two swing arms 3, and a plurality of anti-blocking protrusions 4-2 adapted to the mesh of the arc-shaped filter screen 2 are provided on the side wall of the connecting roller 4-1. The first gear 6 is located on the connecting roller 4-1. When the swing arm 3 drives the anti-blocking roller 4 to move back and forth, the first gear 6 is arranged on the connecting roller 4-1 to cooperate with the gear bar 5, so that the connecting roller 4-1 rotates as the anti-blocking roller 4 moves. When the anti-blocking roller 4 moves and rotates along the bottom surface of the arc-shaped filter screen 2, the graphite blocked in the mesh of the arc-shaped filter screen 2 is pushed open by the anti-blocking protrusions 4-2 on the connecting roller 4-1, thereby avoiding the problem of blockage of the arc-shaped filter screen 2.

[0034] Specifically, it also includes a crushing assembly 8; the crushing assembly 8 includes two crushing rollers 8-1 rotatably installed at the top feed end of the crushing box 1, and the rotating ends of the two crushing rollers 8-1 are provided with second gears 8-2 that mesh with each other. The side wall of the crushing box 1 is provided with a first drive motor 8-3 that drives the crushing rollers 8-1 on one side to rotate. When in use, the crushing rollers 8-1 on one side are driven to rotate by starting the first drive motor 8-3, and the crushing rollers 8-1 on one side drive the crushing rollers 8-1 on the other side to rotate through two meshingly connected second gears 8-2, so that the two crushing rollers 8-1 rotate relative to each other to perform preliminary crushing of the graphite.

[0035] Specifically, it also includes a hammer block assembly 9, which is located below the crushing assembly 8; the hammer block assembly 9 includes a second drive motor 9-1 arranged on the crushing box 1, the driving end of the second drive motor 9-1 extends into the crushing box 1 and is provided with a rotating roller 9-2, and a plurality of evenly distributed hammer heads 9-3 are provided on the side wall of the rotating roller 9-2. When in use, the second drive motor 9-1 is started to drive the rotating roller 9-2 and the plurality of hammer heads 9-3 to rotate, so that the graphite crushed by the crushing assembly 8 is hammered and crushed, thereby ensuring the graphite crushing effect.

[0036] Specifically, an inclined guide plate 10 is provided inside the crushing box 1 and between the crushing assembly 8 and the hammer block assembly 9. By providing the inclined guide plate 10, the graphite crushed by the crushing assembly 8 enters the hammer block assembly 9 for secondary crushing, thereby preventing the graphite crushed by the crushing assembly 8 from directly falling on the hammer block assembly 9 and affecting the hammer effect of the hammer block assembly 9.

[0037] Specifically, a shell 11 is provided at the bottom of the crushing box 1, and the shell 11 is used to collect the crushed graphite. A spiral conveying auger 12 is provided at the bottom of the shell 11. The crushed graphite is conveyed by starting the spiral conveying auger 12, which facilitates the collection and transportation of the crushed graphite.

[0038] Specifically, fixed plates 13 are provided at both ends of the crushing box 1, and an arc-shaped guide rod 14 adapted to the arc-shaped filter screen 2 is provided between the two fixed plates 13. A guide shaft 15 adapted to the arc-shaped guide rod 14 is provided on the side wall of the swing arm 3. When the swing arm 3 swings back and forth, the guide shaft 15 on the swing arm 3 slides on the arc-shaped guide rod 14, thereby ensuring the stability of the swing arm 3 during the reciprocating movement.

[0039] Working principle: During the use of the utility model, when the crusher crushes the graphite, the driving component 7 is started to drive the two swing arms 3 and the anti-blocking roller 4 to move. During the movement of the anti-blocking roller 4, the first gear 6 on the anti-blocking roller 4 cooperates with the gear bar 5 to rotate the anti-blocking roller 4, so that the anti-blocking roller 4 pushes away the graphite that blocks the mesh of the arc filter screen 2 to avoid blockage of the screen or the screen plate.
