Description

A high-efficiency vibrating screen

Technical Field

The utility model relates to the technical field of vibrating screens, in particular to a high-efficiency vibrating screen.

Background technique

The vibrating screen works by utilizing the compound rotation vibration generated by the vibrator excitation. The upper rotating weight of the vibrator makes the screen surface produce a plane rotation vibration, while the lower rotating weight makes the screen surface produce a conical rotation vibration. The combined effect of the two makes the screen surface produce a compound rotation vibration.

The vibrating screen in the prior art is shown in Figure 1, and includes a frame 4. A hopper 401 is installed on the upper end surface of the frame 4. A primary screening device 5, a secondary screening device 6 and a tertiary screening device 7 are installed inside the frame 4 from top to bottom. A vibrating device 8 located outside the frame 4 is installed on the right side of the primary screening device 5, the secondary screening device 6 and the tertiary screening device 7. A collecting device 9 is arranged under the frame 4. During use, fertilizer is poured into the hopper 401, and the vibrating device 8 is turned on to make the primary screening device 5, the secondary screening device 6 and the tertiary screening device 7 vibrate in the horizontal direction. The fertilizer is screened by the primary screening device 5, the secondary screening device 6 and the tertiary screening device 7 in turn and falls downward, and finally falls into the collecting device 9.

However, in the prior art, when the vibrating screen is in use, the feed port is a fixed structure, which causes the material to easily accumulate in the screening device and cannot fall evenly and be screened quickly, thereby reducing the efficiency of material screening. Therefore, it is necessary to propose an efficient vibrating screen to solve the above-mentioned problems.
