An inclined sieve plate 7 is fixedly provided, and the inclined sieve plate 7 is located directly below the ball pressing roller 4. A ball material through hole adapted to the inclined sieve plate 7 is opened on the side of the device housing 1. The advantage of such a setting is that when the driving motor 5 is started, one of the driving shafts 3 will be driven to rotate, and under the action of the two connecting gears 6, the other driving shaft 3 will be driven to rotate in the same direction at the same time, so that the two ball pressing rollers 4 can rotate in the same direction to press the coke powder into balls.

[0023] A plurality of U-shaped frames 8 are fixedly installed at the bottom of the inclined screen plate 7, and hexagonal sliding holes are evenly opened at the bottom of the plurality of U-shaped frames 8. Hexagonal sliding rods 9 are slidably installed in the plurality of hexagonal sliding holes. A knocking block 10 that fits the bottom of the inclined screen plate 7 is fixedly installed at the top of the plurality of hexagonal sliding rods 9, and a movable plate 11 is fixedly installed at the bottom of the plurality of hexagonal sliding rods 9.

The advantage of such a setting is that it is convenient for the staff to directly push the device to move the position, which is more convenient and labor-saving during transportation.

[0029] How this utility works:

[0030] When in use, first put the coke powder and the binder into the mixing box 2, and start the driving motor 5. The operation of the driving motor 5 will drive one of the driving shafts 3 to rotate. The rotation of the driving shaft 3 will drive the stirring shaft 17 and the stirring rod 18 to rotate through the second pulley 19 and the second belt 20 to stir and mix the coke powder and the binder. After the mixture is evenly mixed, the blocking plate 21 can be pulled to make the coke powder automatically fall on the ball pressing roller 4. At this time, under the action of the two connecting gears 6, the other driving shaft 3 will be driven to rotate in the same direction at the same time, so that the two ball pressing rollers 4 can rotate in the same direction to press the coke powder into balls. The formed coke powder balls will fall out of the device shell 1 from the ball material through hole along the inclined screen plate 7, and the coke crushed pieces will fall from the mesh holes of the inclined screen plate 7, and finally fall out of the device shell 1 from the crushed piece discharge port. The screening process of coke powder balls and coke crushed blocks is completed automatically. During this process, the rotation of the driving shaft 3 will also drive the control lever 12 to rotate synchronously through the first pulley 15 and the first belt 16. The rotation of the control lever 12 drives the extrusion plate 13 to rotate. When the extrusion plate 13 rotates to contact the movable plate 11, the extrusion plate 13 continues to rotate to squeeze the movable plate 11 to move downward, and then the knocking block 10 can be driven downward away from the inclined screen plate 7 through the hexagonal slide bar 9. When the extrusion plate 13 rotates to disengage from the movable plate 11, under the elastic force of the reset spring 14, it will automatically squeeze and push the knocking block 10 to reset upward and knock on the inclined screen plate 7, so that the inclined screen plate 7 can be vibrated to prevent the coke powder balls from being stuck in the mesh holes of the inclined screen plate 7 and blocking it all the time. The operation is simple and convenient, saving time and effort, and has good practicality.
