[0019] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings; the following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention. The described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present disclosure.

"Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships.

[0021] See also Figure 1 A graphite material crushing equipment comprises a jaw crusher 1 and a conveyor belt 2 for feeding the jaw crusher 1. In the present 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 also 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 arranged at the corners of the screen 3, and the central axes thereof are all in the vertical direction. The screen 3 is connected to the mounting frame 13 through the springs 4, and a vibration motor 5 is fixedly installed at the lower end of the screen 3 by means of a threaded connection. In this way, the vibration motor 5 makes the screen 3 vibrate continuously during the screening process, which helps to assist the graphite blocks screened out from the screen 3 to roll off.

[0025] See also Figure 3 A collecting hopper 6 is provided on the side of the screen 3 which is inclined to collect the sieved graphite blocks. The collecting hopper 6 is in the shape of a rectangular box with an upward opening, and is mainly composed of a bottom plate and four side walls. The graphite blocks rolling down the screen 3 will fall into the collecting hopper 6 from the upper end of the collecting hopper 6.

[0026] See also Figure 1 , Figure 3 , and a linear drive is provided for driving the collecting bucket 6 to slide back and forth obliquely upward, so that the collecting bucket 6 can move back and forth between the screen 3 and the conveyor belt 2. In one embodiment, the linear drive 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 is fixedly connected to the collecting bucket 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 bucket 6, and a first through hole 10 is provided on the collecting bucket 6, and the first through hole 10 is slidably connected to the first guide rod 14. In this way, the first guide rod 14 can provide support and guidance for the collecting bucket 6, so that the sliding effect is more stable.

[0027] See also Figure 3 The inner bottom surface of the collecting bucket 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 (the left side) toward which it is inclined. When the collecting bucket 6 reaches the conveyor belt 2, the movable side wall 7 is opened, and the graphite blocks in the collecting bucket 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. The collecting hopper 6 is provided with a first motor 8. The housing of the first motor 8 is fixedly mounted on the collecting hopper 6. The end of the output shaft of the first motor 8 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 in the horizontal direction and is located at its lower end, so that the movable side wall 7 is rotated downward to open and rotated upward to close. Driven by the first motor 8, the movable side wall 7 can be rotated 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 located on one side of 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 will be automatically thrown back onto the conveyor belt 2 after a certain period of time, and will then be re-put into the jaw crusher 1 by the conveyor belt 2 for crushing. This is more efficient and convenient, saving workers' labor. Manual picking may sometimes miss some graphite blocks that do not meet the fineness requirements, but these are not easily missed by the screen 3.
