Description

Technical Field

[0001] The utility model belongs to the technical field of vibrating screens, and more specifically, relates to a vibrating screen with automatic opening and closing function. Background Art

[0002] Vibrating screens work by using the reciprocating spiral vibration generated by the excitation of vibrators. The upper rotating weight of the vibrator causes the screen surface to produce planar gyratory vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. The combined effect is to make the screen surface produce compound spiral vibration. Vibrating screens include linear vibrating screens and circular vibrating screens. The vibrating sleeve screen is a type of circular vibrating screen, which is composed of a screen mesh with different screen hole sizes. It is driven to vibrate by a vibrator at the bottom of the sleeve screen, and materials of different particle sizes are screened out at one time. Before screening, it is necessary to manually tighten the upper pressing device to fix the layer screens together to complete the vibrating screening operation. The pressing device of the existing vibrating sleeve screen is usually located directly above the screen box and can be adjusted up and down to adapt to the pressing use requirements of different levels of screen boxes. In order to avoid interference and facilitate the installation of the screen box, the pressing device needs to be adjusted to a relatively high position. The processes of lifting and lowering adjustment and pressing and locking of the pressing device are all manually adjusted, which is inconvenient to operate. The screen box is placed on the platform and is fixed only by the pressing force. The pressing force control is not in place, and the situation of screen box deviation is likely to occur.

[0003] In view of this, the present utility model is specifically proposed. Summary of the Utility Model
