[0016] Optionally, the elastic rod is made of 60Si2Mn steel.
[0017] By adopting the above technical solution, the elastic rod is made of 60Si2Mn steel, and its performance is optimized through heat treatment, making it suitable for low and medium frequency vibration scenarios.
[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0019] The technical solution of this application uses a vibration mechanism in conjunction with a screen to screen the ore on the screen. The nut can install the positioning vertical rod on the screen. When the screen vibrates, the elastic rod will also vibrate, which will drive the striking ball to vibrate. The striking ball can then strike the screen, reducing the occurrence of screen clogging and improving the efficiency and quality of ore screening. Attached Figure Description

[0027] Please see Figure 1-4 This application provides a technical solution: an automatic screening device for ores of different particle sizes, including a screening shell 1 and three sets of screens 3 set inside the screening shell 1. Multiple sets of positioning vertical rods 4 are slidably passed through the inner wall of the middle of the three sets of screens 3. Nuts 5 are threadedly connected to the outer wall of the positioning vertical rods 4 located around each set of screens 3. Elastic rods 6 are welded to the outer wall of the positioning vertical rods 4 located between each two screens 3.

[0028] In the technical solution of this application, the ore on the screen 3 can be screened by the cooperation of the vibration mechanism and the screen 3. The nut 5 can install the positioning vertical rod 4 on the screen 3. When the screen 3 vibrates, the elastic rod 6 will also vibrate, which will drive the striking ball 7 to vibrate. The striking ball 7 can then strike the screen 3. The spacing of the screen 3 is set to the elastic range of the elastic rod 6 to reduce the occurrence of screen 3 clogging and enhance the efficiency and quality of ore screening.
[0029] The elastic rod 6 is made of 60Si2Mn steel, and its performance is optimized through heat treatment, making it suitable for low- and medium-frequency vibration scenarios.
