When the coke block falls to the upper end of the screen plate 2, the coke particles directly pass through the screen plate 2 and fall vertically to the lower end of the baffle 31. Then, the medium coke and the large coke roll down through the screen plate 2 for screening, which is convenient for screening the mixed coke. The screen plate 2 is inclined with respect to the ground plane, and the baffle 31 is inclined with respect to the ground plane. A material guide assembly is connected to one side of the upper end of the frame 1, and the material guide assembly can evenly disperse the falling coke blocks to various places on the upper end of the screen plate 2. A mounting plate 7 is connected to the upper part of one side of the material guide assembly, and a motor 8 is connected to the middle part of one side of the mounting plate 7. A screw rod 9 is connected to the output end of the motor 8. Boxes 14 are connected to both sides of the upper end of the frame 1, and transmission assemblies are connected to both sides of the outer side of the screw rod 9. Connecting rods 21 are connected to one side of the two transmission assemblies, and one end of the two connecting rods 21 extends through and extends to one side of the two boxes 14 respectively. The material guide assembly includes a support plate 5, and a material guide hopper 6 is connected to one end of the support plate 5. One side of the screw rod 9 extends through and extends to one side of the material guide hopper 6. A slider 10 is slidably connected to the middle part of the outer side of the screw rod 9, and guide plates 11 are connected to both sides of the slider 10. A material guide block 12 is connected to the middle part of the lower end of the inner wall of the material guide hopper 6, and both sides of the lower end of the material guide hopper 6 are connected to a discharge pipe 13; The coke blocks are transported to the inside of the guide hopper 6. The coke blocks enter the guide hopper 6 and are dispersed into the two discharge pipes 13 through the guide block 12. They are transported to the upper end of the sieve plate 2 through the two discharge pipes 13. At the same time, some coke blocks fall to the upper ends of the two guide plates 11. The screw rod 9 and the slider 10 are matched to make the motor 8 drive the screw rod 9 to rotate, which can drive the slider 10 to move. Then, the slider 10 drives the two guide plates 11 to move inside the guide hopper 6, so that the fallen coke blocks can be guided to various places inside the lower guide hopper 6, so that the coke blocks can be evenly distributed to various places on the upper end of the sieve plate 2, so as to avoid the coke blocks falling to one place on the upper end of the sieve plate 2 all the time and causing damage to the falling place. One end of the two connecting rods 21 is respectively connected to one side of the outer wall of the two transmission belts 20.

[0017] Guide rods are connected to both sides of the inner wall of the guide hopper 6, and two guide plates 11 are respectively provided with openings corresponding to the two guide rods. The two guide rods are respectively located inside the two openings, and the two guide plates 11 are respectively located outside the two guide rods and slide; When the slider 10 drives the two material guide plates 11 to move, the two guide rods can ensure the stability of the material guide plates 11 and avoid damage to the material guide plates 11 .

[0018] The transmission assembly includes a first transmission wheel 15, and the number of the first transmission wheels 15 is two groups. The outer side of the first transmission wheel 15 is connected to the second transmission wheel 17 through a belt 16. The inner wall of the second transmission wheel 17 is connected to a first rotating rod 18. One end of the first rotating rod 18 extends through the inside of the box body 14. The inner wall of the box body 14 is connected to a second rotating rod 19 away from the first rotating rod 18. The outer sides of the first rotating rod 18 and the second rotating rod 19 are connected to a transmission belt 20. When the screw rod 9 rotates, the two first transmission wheels 15 are driven to rotate, so that the two first rotating rods 18 are driven to rotate through the belt 16, which can drive the transmission belt 20 for transmission, so that the second rotating rod 19 rotates following the transmission of the transmission belt 20, so that the position of the two connecting rods 21 can be adjusted through the transmission belt 20, and the position of the cleaning component can be adjusted.

[0019] The two boxes 14 are respectively provided with moving openings at the locations corresponding to the two connecting rods 21. A connecting block 29 is connected to the middle of one side of the inner wall of the two boxes 14. A protective plate 30 is connected to one side of the two connecting blocks 29. The two protective plates 30 are respectively located inside the two moving openings. The connecting block 29 is located inside the transmission belt 20, and the protective plate 30 can cover the moving opening to prevent the moving opening from being exposed. When the coke block falls to the upper end of the screen plate 2, it bounces into the box body 14 through the moving opening, which is convenient for protecting the transmission belt 20 inside the box body 14.

[0020] A cleaning assembly is connected between the two connecting rods 21, and the cleaning assembly can be used to clean the coke blocks remaining on the upper end of the sieve plate 2. The cleaning assembly includes a shell 22, and the number of the shell 22 is two groups. A sliding rod 23 is connected to the middle of the lower end of the inner wall of the two shells 22. The upper ends of the two sliding rods 23 extend through and extend to the upper ends of the two shells 22 respectively. Buffer springs 24 are connected to the corresponding sliding rods 23 at the upper ends of the inner walls of the two shells 22. The two buffer springs 24 are respectively sleeved on the outside of the two sliding rods 23. The lower ends of the two buffer springs 24 are connected to moving blocks 25. The two moving blocks 25 are respectively located on the outside of the two sliding rods 23 and slide. A fixed rod 26 is connected to the middle of one side of the two moving blocks 25. One end of the two fixed rods 26 extends through and extends to one side of the two shells 22 respectively. A cleaning block 27 is connected between the two fixed rods 26. The upper and lower parts of one side of the cleaning block 27 are connected to cleaning teeth 28. A moving groove is opened at the corresponding fixed rod 26 of the shell 22, and the fixed rod 26 is located inside the moving groove. The moving block 25 slides on the outside of the slide rod 23, and the moving block 25 is buffered by the buffer spring 24, so that the position of the cleaning block 27 can be buffered, so that the lower end of the cleaning block 27 contacts the upper end of the screen plate 2. When the positions of the two connecting rods 21 are adjusted, the positions of the two shells 22 and the cleaning block 27 can be driven to move, so that the cleaning block 27 slides on the upper end of the screen plate 2. The multiple cleaning teeth 28 can push the coke blocks that block the upper end of the screen plate 2 to move to one side, which can avoid the coke blocks that block the upper end of the screen plate 2.

[0021] Working principle: When using the device, the device can be moved to a suitable position, and then the mixed coke to be screened is put into the guide hopper 6. Some of the mixed coke falls to the upper end of the two guide plates 11. The motor 8 works to drive the screw rod 9 to rotate, so that the slider 10 located outside the screw rod 9 moves back and forth. The slider 10 drives the two guide plates 11 to move, which can guide some of the mixed coke, making it easier to evenly distribute the mixed coke to various places inside the guide hopper 6. The mixed coke inside the guide hopper 6 passes through the guide block 12. The coke particles are discharged through two discharge pipes 13 respectively, so that the mixed coke can evenly fall to the upper end of the screen plate 2. When the mixed coke falls to the upper end of the screen plate 2, it rolls to one side of the screen plate 2. The smaller coke particles directly pass through the screen plate 2 and fall to the upper end of the baffle 31. The coke particles fall to the ground on one side through the baffle 31. Then, during the coke particles rolling down from the upper end of the screen plate 2, the medium coke particles smaller than the screen mesh directly pass through the screen plate 2 and fall to the upper end of the ground. The large coke particles roll through the screen plate 2 and fall to the ground on one side of the screen plate 2. The large coke particles, medium coke particles and coke particles inside the mixed coke can be screened. The two second transmission wheels 17 are driven to rotate by the two belts 16, so that the first rotating rod 18 rotates, driving the transmission belt 20 to transmit the power. At the same time, the second rotating rod 19 rotates following the transmission belt 20, driving the two connecting rods 21 to follow the transmission belt 20 to move, driving the cleaning block 27 located at the upper end of the sieve plate 2 to move, and sliding the moving block 25 outside the sliding rod 23, the buffer spring 24 buffers the moving block 25, so that the cleaning block 27 contacts with one side of the upper end of the sieve plate 2, and when the transmission belt 20 drives the two connecting rods 21 to move, it can drive the two shells 22 and the cleaning block 27 located at the upper end of the sieve plate 2 to move, and the cleaning teeth 28 on one side of the cleaning block 27 can push the coke block stuck in the sieve hole to one side of the sieve plate 2, helping the coke block to smoothly roll down to one side of the sieve plate 2, and avoiding the sieve plate 2 from being blocked.
