[0020] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0021] Refer to Figures 1-4As shown in the figure, a horizontal air flow sieve includes a housing 1. At the top end inside the housing 1, a feeding port 2 is provided. During use, the particles are put into the housing 1 through the feeding port 2. Then, the first vibrator 13 is started. The first vibrator 13 vibrates the coarse screening plate 3 to make the particles slide into the blanking port 15, and the screened particles enter the storage box 10 at the bottom of the coarse screening plate 3 for storage. At the same time, in order to accelerate the screening process, the upper air fan 11 is used for auxiliary treatment. An upper mounting plate 5 is installed near the upper end inside the housing 1. On one side of the upper surface of the upper mounting plate 5, a partition plate 4 is installed. On one side of the partition plate 4 on the upper surface of the upper mounting plate 5, a first vibrator 13 is installed. The top end of the first vibrator 13 is fixedly installed with a coarse screening plate 3, and a chute is provided on one side of the coarse screening plate 3. A limiting plate 14 is arranged in the chute of the coarse screening plate 3 on the upper surface of the upper mounting plate 5. A storage box 10 is installed at the bottom end of the coarse screening plate 3 on one side of the housing 1. A lower air fan 12 is installed at the top end of the upper mounting plate 5 on one side of the housing 1. An upper air fan 11 is fixedly installed at the top end inside the housing 1.

[0022] Further, an installation box 6 is installed on one side of the bottom of the upper mounting plate 5. A first motor 19 is installed at the top end inside the installation box 6. The particles enter the upper surface of the upper mounting plate 5 at the coarse screening plate 3, and then the lower air fan 12 is turned on to blow the particles into the material dropping port 15 of the upper mounting plate 5 and enter the screening plate 7 at the opening of the material dropping port 15. The output end of the first motor 19 is installed with a first rotating shaft 20. A first belt pulley 21 is installed on the shaft surface of the first rotating shaft 20. A belt 22 is sleeved inside the first belt pulley 21. A second belt pulley 23 is sleeved on one side inside the belt 22. Then, the first motor 19 is started. The first motor 19 drives the first rotating shaft 20, the first rotating shaft 20 drives the first belt pulley 21 and the belt 22. Then, the second belt pulley 23 drives the second rotating shaft 25, the second rotating shaft 25 drives the first gear 24, the first gear 24 meshes with and drives the second gear 27. Further, the second gear 27 drives the second connecting member 32 to rotate along the second rotating shaft 25. At the same time, the second gear 27 drives the third gear 28 and the first connecting member 30 at the bottom. Thus, the first connecting member 30 drives the fourth rotating shaft 31 and the fourth gear 29 to move. The third gear 28 drives the fourth gear 29 to rotate the screening plate 7. Further, the slight swing of the screen is realized by the eccentric wheel assembly, enhancing the ability of the particles to pass through the screen. The second belt pulley 23 is sleeved inside with the second rotating shaft 25. A first gear 24 is sleeved on the outer surface of the second rotating shaft 25. A second gear 27 is installed on one side and meshed with the first gear 24. A third gear 28 is arranged at the bottom of the second gear 27. The second gear 27 and the third gear 28 are installed through the outer surface by a third rotating shaft 26. A second connecting member 32 is sleeved on the shaft surfaces of the third rotating shaft 26 and the second rotating shaft 25. The bottom end of the third rotating shaft 26 is sleeved with a first connecting member 30 on the lower surface of the third gear 28. A fourth rotating shaft 31 is sleeved inside one end of the first connecting member 30. A fourth gear 29 is sleeved on the shaft surface of the fourth rotating shaft 31. And the third gear 28 and the fourth gear 29 are meshed and connected. The screening plate 7 is fixedly installed on the lower surface of the fourth rotating shaft 31.

[0023] Further, a lower mounting plate 9 is installed near the bottom inside the housing 1. A sliding plate 8 is arranged on the upper surface of the lower mounting plate 9. While the screening plate 7 is rotating, the second motor 33 is started. The second motor 33 drives the rotating rod 35 at the top, so that the rotating rod 35 drives the motor 37 and the fan blade 38 to rotate. When the motor 37 and the fan blade 38 are rotating, the limiting rod 39 is driven to rotate. The limiting rod 39 drives the positioning member 41. The positioning member 41 rotates to make the motor 37 rotate along the positioning rod 36. Through the cooperation of the above components, the multi-directional rotation of the fan blade 38 is realized, so that a vortex is formed in the air flow during screening to help fine particles penetrate. A second motor 33 is arranged in the middle of the upper surface of the lower mounting plate 9. The output end of the second motor 33 is installed with a rotating rod 35. A rotating member 34 is sleeved on the outer surface of the rotating rod 35. One side of the top of the rotating member 34 is installed with a motor 37. The output end of the motor 37 is installed with a fan blade 38. A positioning plate 40 is arranged at the top of the second motor 33. Limiting rods 39 are installed on both sides of the top of the positioning plate 40. The limiting rods 39 penetrate through the outer surface of the positioning plate 40 and are installed with positioning members 41. The positioning rod 36 penetrates through the outer surface between the positioning member 41 and the motor 37 for installation. A plurality of groups of second vibrators 16 are arranged at the bottom of the lower mounting plate 9. Finally, the particles fall from the screening plate 7 and enter the lower mounting plate 9 through the sliding plate 8. Then, a plurality of groups of second vibrators 16 are started. The aperture of the material dropping port 15 of the lower mounting plate 9 is the smallest and is specially used for screening fine particles. The vibration frequency of the second vibrator 16 is adjusted to a high frequency to improve the efficiency of the fine particles passing through the screen, so that the particles enter the extraction box 17. Then, the extraction box 17 is pulled out through the handle 18. The extraction box 17 is installed on the upper surface of the bottom of the housing 1 on one side of the second vibrator 16. One end of the extraction box 17 penetrates through the outer surface of the housing 1 and is installed with a handle 18. Material dropping ports 15 are formed on the outer surfaces of the upper mounting plate 5 and the lower mounting plate 9.

[0024] Working principle and implementation method: Start the first vibrator 13 to vibrate the coarse screening plate 3, so that the particles slide into the material dropping port 15. The larger particles screened out enter the storage box 10 for storage. The upper air fan 11 assists in accelerating the screening process and helps the particles pass through the screen smoothly through the air flow. The crushed particles fall from the coarse screening plate 3 into the upper mounting plate 5. Start the lower air fan 12 to send the particles into the screening plate 7 for further screening. The first motor 19 drives a series of gear systems to realize the rotation of the screening plate 7, and uses the eccentric wheel assembly to make the screen swing slightly to enhance the ability of the particles to pass through the screen. Start the second motor 33 to drive the rotation of the rotating rod 35, the motor 37 and the fan blade 38 to form a vortex air flow to assist the fine particles to penetrate the screen. After the screening is completed, the particles fall from the screening plate 7 and enter the lower mounting plate 9. Further screening is carried out through a plurality of groups of second vibrators 16. The fine particles pass through the second vibrator 16 with adjusted frequency to improve the efficiency of passing through the screen, and finally enter the extraction box 17.
