[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] The embodiment of the utility model discloses a sieving device for fluorescent powder specially used in pet growth light supplementary lamps.

[0026] Example 1

[0027] The utility model provides Figure 1-5 The shown device is a screening device for fluorescent powder specially used for pet growth fill light, including a screen box 1 and a screening mechanism 2. The screen box 1 is provided with a discharge port 3, and a support rod is provided on the bottom inner wall of the screen box 1. The screening mechanism 2 includes a conveying cylinder 6, a sleeve 7 and a motor 10. One end of the conveying cylinder 6 passes through the screen box 1 and is fixedly connected to the screen box 1. The other end of the conveying cylinder 6 is fixed on the top outer wall of the support rod. The sleeve 7 is nested in the conveying cylinder 6. The conveying cylinder 6 and the sleeve 7 are both provided with sieve holes. The positions, quantities and sizes of the two sieve holes are consistent. The motor 10 is installed on the outer wall of the conveying cylinder 6. The output end of the motor 10 passes through the interior of the conveying cylinder 6 and is fixedly connected to an auger 11. The other end of the auger 11 is rotatably connected to the inner wall of the conveying cylinder 6. The conveying cylinder 6 is provided with a feed port 8 and a discharge port 9. The feed port 8 passes through the screen box 1 and extends to the outside of the screen box 1.

[0028] The utility model provides a screening device for fluorescent powder specially used for pet growth fill light. A plurality of support blocks 4 are installed on the bottom outer wall of the screen box 1. The plurality of support blocks 4 are evenly distributed at the four corners of the bottom of the screen box 1, which can provide stable support and ensure the stability of the device during use.

[0029] The utility model provides a screening device for fluorescent powder specially used for pet growth supplementary light. A guide plate 5 is provided on the bottom inner wall of the screen box 1. The guide end of the guide plate 5 corresponds to the position of the discharge port 3, which can facilitate the complete diversion of the screened fluorescent powder to the outside to avoid residue at the bottom of the screen box 1.

[0030] The utility model provides a sieving device for phosphor powder specially used for pet growth supplementary light. A guide groove is provided on the outer wall of the conveying cylinder 6, and a guide block is provided on the inner wall of the sleeve 7. The conveying cylinder 6 is connected to the guide groove through the guide block, which can improve the stability of the sleeve 7 during movement and prevent the sleeve 7 from rotating randomly during use, affecting the use effect.

[0031] Based on the first embodiment, Figure 1-5 As shown, the utility model is a screening device for fluorescent powder specially used for pet growth fill light. A fixing frame 12 is provided on the outer wall of the sleeve 7, and a rotating seat 13 is provided on the outer wall of the fixing frame 12. A screw 14 is threadedly connected to the screen box 1, and one end of the screw 14 is fixedly connected to the rotating head 15, and the other end of the screw 14 is connected to the rotating seat 13, which can conveniently drive the sleeve 7 to move and improve the convenience of operation.

[0032] The utility model provides a sieving device for fluorescent powder specially used for pet growth supplementary light. The fixing frame 12 is connected to the fixed end of the rotating base 13, and the screw 14 is connected to the rotating end of the rotating base 13. This can prevent the fixing frame 12 from rotating with the rotation of the screw 14, which affects the use effect.

[0033] During use, the fluorescent powder to be screened is conveyed to the inside of the conveying cylinder 6 through the feed port 8, and then the motor 10 is started to drive the auger 11 to rotate. In the process of the auger 11 driving the fluorescent powder to move, the fluorescent powder that meets the requirements will fall into the screen box 1 from the sieve hole, and then be discharged to the outside through the discharge port 3 under the action of the guide plate 5, and the fluorescent powder that does not meet the requirements will be discharged to the outside through the discharge port 9. When it is necessary to adjust the particle size of the screened fluorescent powder according to specific needs, the screw 14 is driven to rotate by the rotating head 15. Since the screw 14 is threadedly connected to the screen box 1, the sleeve 7 can be driven to move by the fixed frame 12 to adjust the aperture of the sieve hole. When the apertures set on the conveying cylinder 6 and the sleeve 7 completely coincide, the aperture of the sieve hole is the largest, and otherwise it gradually shrinks.

[0034] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
