[0021] See also Figure 1 A graphite material crushing equipment includes a jaw crusher 1 and a conveyor belt 2 for feeding the jaw crusher 1. In this application, the direction of the graphite raw material on the conveyor belt 2 is defined as the front, the opposite direction is defined as the rear, and the direction perpendicular to the front and rear directions in the horizontal plane is defined as the left and right directions.

[0022] See also Figure 1 A rectangular screen 3 is fixedly installed below the discharge port of the jaw crusher 1 (with a certain distance therebetween) and is inclined toward the right side of the jaw crusher 1 (its right side is inclined downward along the horizontal plane). It is used to screen out graphite blocks that do not meet the requirements (larger) and make them roll down along the inclined direction of the screen 3. Graphite blocks that meet the fineness requirements will pass through the screen 3 and continue to fall.

[0023] See also Figure 1 In one embodiment, a mounting frame 13 is further included to provide a mounting or supporting position for each component.

[0024] See also Figure 2 、 Figure 3 、 Figure 4 、 Figure 5In one embodiment, four parallel springs 4 are provided at the corners of the screen 3, with their central axes all oriented vertically. The screen 3 is connected to the mounting frame 13 via the springs 4, and a vibration motor 5 is fixedly mounted at the lower end of the screen 3 via a threaded connection. This arrangement allows the vibration motor 5 to continuously vibrate the screen 3 during the screening process, helping to roll off the graphite blocks screened off the screen 3.

[0025] See also Figure 3 A collecting hopper 6 is provided on the side of the screen 3 that is tilted toward the side thereof. The collecting hopper 6 is in the shape of a rectangular box that opens upward and mainly consists of a bottom plate and four side walls. Graphite blocks that roll down the screen 3 will fall into the collecting hopper 6 from the upper end thereof.

[0026] See also Figure 1 、 Figure 3 , and a linear drive component is provided for driving the collecting hopper 6 to slide back and forth obliquely upward, so that the collecting hopper 6 can move back and forth between the screen 3 and the conveyor belt 2. In one embodiment, the linear drive component is a first cylinder 12, and the cylinder body of the first cylinder 12 is fixedly mounted obliquely upward on the mounting frame 13, and the end of the telescopic rod thereof is fixedly connected to the collecting hopper 6 by welding, because the cylinder is more suitable for driving reciprocating motion and is easy to set up. Furthermore, a first guide rod 14 is welded on the mounting frame 13 along the sliding direction of the collecting hopper 6, and a first through hole 10 is provided on the collecting hopper 6, and is slidably connected to the first guide rod 14 through the first through hole 10. With this arrangement, the first guide rod 14 can provide support and guidance to the collecting hopper 6, making the sliding effect more stable.

[0027] See also Figure 3 The inner bottom surface of the collecting hopper 6 is inclined toward the side where the jaw crusher 1 is located (the left side is inclined downward), and a movable side wall 7 that can be opened and closed is provided on the side (left side) toward which it is inclined. When the collecting hopper 6 reaches the conveyor belt 2, the movable side wall 7 is opened, and the graphite blocks in the collecting hopper 6 will roll onto the conveyor belt 2 along the inclined direction of its bottom surface, and then be put back into the jaw crusher 1 for crushing.

[0028] See also Figure 3In one embodiment, the movable side wall 7 is rotatably connected to the collecting hopper 6. A first motor 8 is provided on the collecting hopper 6. The housing of the first motor 8 is fixedly mounted on the collecting hopper 6. The end of the output shaft is fixedly connected to the rotating shaft of the movable side wall 7 by welding, and is used to drive the movable side wall 7 to open and close by rotating. With this arrangement, the structure is easy to implement and the effect is stable. Furthermore, the rotating shaft of the movable side wall 7 is horizontal and located at its lower end, so that the movable side wall 7 rotates downward to open and rotates upward to close. Driven by the first motor 8, the movable side wall 7 can rotate downward to be flush with the inner bottom surface of the collecting hopper 6 when opened. A baffle 9 is fixedly provided at both ends of the movable side wall 7 on one side inside the collecting hopper 6. With this arrangement, the structure is more reasonable and the effect of the graphite blocks in the collecting hopper 6 rolling onto the conveyor belt 2 is better.

[0029] Working principle: Graphite blocks with a size larger than the required fineness will be screened out by the screen 3, and automatically thrown back onto the conveyor belt 2 after a certain period of time, and then re-entered into the jaw crusher 1 by the conveyor belt 2 for crushing. It is more efficient and more convenient, saving workers' labor. Manual picking sometimes misses some graphite blocks that do not meet the fineness requirements, but it is not easy to be screened out by the screen 3.
