However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: a screening and ore dressing device with adjustable pores, including a base 1. A support frame 2 is fixedly connected to the surface of the base 1. A screening box 6 is arranged inside the support frame 2. A connecting rod 5 is fixedly connected to the surface of the support frame 2. One end of the connecting rod 5 is fixedly connected to the screening box 6. A first screening mesh 7 and a second screening mesh 8 are slidably connected inside the screening box 6. A metal rotating column 16 is fixedly connected to the surface of the first screening mesh 7. Round holes 13 are formed on the surface of the second screening mesh 8. The metal rotating column 16 is inserted into the round holes 13. A fixing block 14 is fixedly connected to the surface of the second screening mesh 8. A clamping groove 15 is formed on the surface of the fixing block 14. A slider 17 is slidably connected inside the metal rotating column 16. A connecting column 18 is fixedly connected to the surface of the slider 17. A spring 19 is sleeved around the connecting column 18. One end of the spring 19 is fixedly connected to the surface of the slider 17. One end of the connecting column 18 is fixedly connected to a cylindrical block 20. A limiting plate 21 and a handle 22 are fixedly connected to the surface of the cylindrical block 20. The limiting plate 21 is inserted into the clamping groove 15. A handle sleeve 23 is fixedly connected to the surface of the handle 22. The handle sleeve 23 is made of rubber material, which can improve the comfort of holding the handle here. A magnet 24 is fixedly connected to the surface of the slider 17. The magnet 24 is adsorbed and connected to the inner surface of the metal rotating column 16, which can further improve the firmness of the connection between the slider 17 and the metal rotating column 16 here. A limiting groove 9 is formed on the inner side surface of the screening box 6. A limiting block 10 is fixedly connected to the surface of the second screening mesh 8. The limiting block 10 is slidably connected with the limiting groove 9, which can prevent the second screening mesh 8 from rotating together when the first screening mesh 7 rotates. A feed hopper 3 is fixedly connected to the top surface of the support frame 2. A feed pipe 4 is fixedly connected to the bottom of the feed hopper 3, which can prevent the crushed ore from spilling outside the screening box 6 during the process of entering the screening box 6.

[0025] Embodiment 2

[0026] Please refer to Figures 1-5 , a receiving box 12 is arranged on the surface of the base 1. The receiving box 12 is located directly below the screening box 6, which can collect the required crushed ore after screening. An electric telescopic rod 11 is fixedly connected to the surface of the support frame 2. The output end of the electric telescopic rod 11 is fixedly connected to the surface of the screening box 6, which can change the inclination angle of the screening box 6 and improve the screening effect.

[0027] Working principle: During use, first put the crushed ore into the feeding hopper 3. The crushed ore will fall into the screening box 6 along the feeding pipe 4 at the bottom of the feeding hopper 3. The required crushed ore will fall into the receiving box 12 through the pores of the first screening net 7 and the second screening net 8. When it is necessary to change the pore size of the screening net, hold the handle 22 and pull it outwards. The handle 22 drives the cylindrical block 20, the connecting column 18 and the slider 17 to move away from the fixed block 14. The slider 17 slides inside the metal rotating column 16 and compresses the spring 19. Then rotate the handle 22 to stagger the pores of the first screening net 7 and the second screening net 8. When adjusted to the appropriate specification, release the handle 22. The slider 17 slides inside the metal rotating column 16 under the elastic force of the spring 19 and the limiting plate 21 will be inserted into the card slot 15 on the fixed block 14. Finally, the magnet 24 on the slider 17 adsorbs on the top surface inside the metal rotating column 16, realizing the rotation of the dissenting screening net, making the gaps between the first screening net 7 and the second screening net 8 stagger each other, so as to achieve the purpose of adjusting the pores, enabling the device to achieve the purpose of screening ores of different size specifications, further improving the applicable range of the ore dressing device. When it is necessary to change the inclination angle of the screening box 6, start the electric telescopic rod 11 for adjustment. If the pores of the second screening net 8 and the first screening net 7 are blocked, start the electric telescopic rod 11. The telescopic rod of the electric telescopic rod 11 drives the screening box 6 to move up and down and makes the first screening net 7 and the second screening net 8 vibrate, so as to avoid pore blockage. The inclination angle of the screening box 6 can be adjusted, which can better improve the screening effect of the ore. At the same time, driving the screening box 6 to move up and down by the electric telescopic rod 11 and making the screening box 6 vibrate can also avoid the pores of the first screening net 7 and the second screening net 8 from being blocked.

[0028] The above are only the preferred embodiments of the present invention, and are not limitations to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
