As used here, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the existence of features, steps, operations, devices, components, and / or their combinations.

[0031] Refer to Figures 1-6 , a drum screening device for solid waste recycling and brick making, including a cross plate 3. Two vertical plates 4 are symmetrically and fixedly connected to the upper end of the cross plate 3. Two inclined mounting plates 6 are fixedly connected to the upper ends of the two vertical plates 4. A drum 7 is commonly penetrated through the two inclined mounting plates 6. The drum 7 is rotatably connected to the two inclined mounting plates 6 through two bearings respectively. A plurality of screening holes 8 are provided on the outer side of the drum 7. Further, the screening holes 8 are only located at the position where the drum 7 is between the two inclined mounting plates 6;

[0032] Among them, a driving mechanism is further included. The driving mechanism is used to drive the drum 7 to rotate. The driving mechanism includes a mounting seat 22 installed on the right side of the left inclined mounting plate 6. A driving motor 9 is installed on the mounting seat 22. The output shaft of the driving motor 9 penetrates through the inclined mounting plate 6 and is fixedly connected to a rotating shaft 16. A gear 11 is installed on the rotating shaft 16. A toothed ring 12 is installed on the drum 7. The gear 11 meshes with the toothed ring 12. By starting the driving motor 9, the gear 11 can drive the toothed ring 12 to rotate;

[0033] Among them, a bottom plate 1 is further included. A plurality of universal wheels 2 are installed at the lower end of the bottom plate 1. The plurality of universal wheels 2 are all locking wheels, which ensures the stability during use. An opening 5 is provided on the cross plate 3;

[0034] Among them, a jitter mechanism is further included. The jitter mechanism is used to drive the horizontal plate 3 to jitter, improving the screening effect. The jitter mechanism includes four third piston cylinders 23 fixedly connected to the upper end of the bottom plate 1. Each third piston cylinder 23 is internally provided with a third piston block 28 that can slide up and down. The upper end of each third piston block 28 is fixedly connected to a fixing rod 29. The upper ends of multiple fixing rods 29 are fixedly connected to the lower end of the horizontal plate 3. The left side of the inclined mounting plate 6 on the left is fixedly connected to a mounting block 30. A first piston cylinder 13 is mounted on the left side of the mounting block 30. A first piston block 26 that can slide up and down is arranged inside the first piston cylinder 13. The lower end of the first piston block 26 is fixedly connected to a round head abutting rod 25. A cam 15 is mounted on the rotating shaft 16. The cam 15 abuts against the lower end of the round head abutting rod 25;

[0035] The bottom spaces of every two adjacent third piston cylinders 23 are communicated through a second connecting pipe 24. The inner top space of the first piston cylinder 13 is communicated with one of the second connecting pipes 24 through a first connecting pipe 14. The inner top space of the first piston cylinder 13, the first connecting pipe 14, the communication of multiple second connecting pipes 24 and the inner bottom spaces of multiple third piston cylinders 23 are all filled with hydraulic oil. By using hydraulic oil, the transmission of force can be made more stable. Since the cam 15 always abuts against the round head abutting rod 25, as the cam 15 rotates, the first piston block 26 will reciprocate up and down;

[0036] Among them, an atomizing dust suppression mechanism is further included. The atomizing dust suppression mechanism is used to reduce the dust generated during the screening process. The atomizing dust suppression mechanism includes a liquid spraying pipe 10 fixedly connected between two inclined mounting plates 6. A plurality of atomizing nozzles are equidistantly mounted at the lower end of the liquid spraying pipe 10. A second piston cylinder 19 is mounted on the upper end of the bottom plate 1. A second piston block 27 that can slide up and down is arranged inside the second piston cylinder 19. The upper end of the second piston block 27 is fixedly connected to a connecting rod 18. The right side of the vertical plate 4 on the right is fixedly connected to a connecting plate 17. The upper end of the connecting rod 18 is fixedly connected to the lower end of the connecting plate 17. The inner bottom space of the second piston cylinder 19 is communicated with a first one-way pipe 20. The inner bottom space of the second piston cylinder 19 is communicated with the inside of the liquid spraying pipe 10 through a second one-way pipe 21. One-way valves are installed inside both the first one-way pipe 20 and the second one-way pipe 21. The flow direction of the one-way valve inside the first one-way pipe 20 is unidirectional from the outside into the second piston cylinder 19, and the flow direction of the one-way valve inside the second one-way pipe 21 is unidirectional from the second piston cylinder 19 into the inside of the liquid spraying pipe 10. The other end of the first one-way pipe 20 is connected to an external water tank during use.

[0037] In the present invention, after the staff moves the equipment to the required position through the universal wheels 2, the universal wheels 2 are locked, and the driving motor 9 is started. The output shaft thereof drives the rotating shaft 16 to rotate. The gear 11 on the rotating shaft 16 meshes with the gear ring 12 on the drum 7, thereby driving the drum 7 to rotate around its axis. At this time, solid waste is put in from the right side of the drum 7. The rotation of the drum 7 causes the solid waste to tumble inside the drum 7, and screening is achieved through the screening holes 8;

[0038] While the rotating shaft 16 rotates, it also drives the cam 15 to rotate. The rotation of the cam 15 continuously pushes the round-headed abutting rod 25 to move up and down, thereby driving the first piston block 26 in the first piston cylinder 13 to reciprocate up and down. The movement of the first piston block 26 is transmitted to the second connecting pipe 24 and the third piston cylinder 23 through hydraulic oil, causing the third piston block 28 to slide up and down in the third piston cylinder 23. Since the third piston block 28 is fixedly connected to the cross plate 3, the cross plate 3 and the drum 7 thereon vibrate, and the vibration improves the screening effect and reduces the blockage of the screen;

[0039] Further, during the vibration, the vertical plate 4 drives the connecting plate 17 to reciprocate up and down. The connecting plate 17 drives the second piston block 27 in the second piston cylinder 19 to reciprocate up and down through the connecting rod 18. The movement of the second piston block 27 causes a negative pressure to be generated in the second piston cylinder 19, and water is inhaled from the outside through the first one-way pipe 20. When the second piston block 27 moves downward, the water in the second piston cylinder 19 is pressed into the liquid spraying pipe 10 through the second one-way pipe 21. Multiple atomizing nozzles at the lower end of the liquid spraying pipe 10 atomize the water and spray it into the air around the drum 7, where it combines with the dust and settles, effectively reducing the dust concentration generated during the screening process.

[0040] The present invention also discloses a method for using a drum screening device for solid waste recycling and brick making. Using the above screening device, it includes the following steps:

[0041] First step: After the staff moves the equipment to the required position through the universal wheels 2, the universal wheels 2 are locked;

[0042] Second step: Start the driving motor 9. The output shaft thereof drives the rotating shaft 16 to rotate. The gear 11 on the rotating shaft 16 meshes with the gear ring 12 on the drum 7, thereby driving the drum 7 to rotate around its axis. At this time, solid waste is put in from the right side of the drum 7;

[0043] Third step: Place a collection box on the upper end of the bottom plate 1, and the collection box penetrates through the opening 5;

[0044] Fourth step: When the overall screening is completed, open the lock of the universal wheels 2 and move the entire equipment again.
