Description

Vibrating screen for mining machinery

Technical Field

The utility model relates to the technical field of vibrating screens, in particular to a vibrating screen for mining machinery.

Background

The vibrating screen works by utilizing reciprocating rotary vibration generated by vibrator excitation. The upper rotary weight of the vibrator makes the screen surface produce plane rotary vibration, while the lower rotary weight makes the screen surface produce conical surface rotary vibration, and the combined effect of the upper rotary weight and the lower rotary weight makes the screen surface produce compound rotary vibration. The vibration track is a complex space curve. The curve is projected as a circle on the horizontal plane and as an ellipse on the vertical plane. The vibration force of the upper and lower rotary weights is adjusted to change the amplitude. And the curve shape of the movement track of the screen surface and the movement track of the material on the screen surface can be changed by adjusting the space phase angles of the upper heavy hammer and the lower heavy hammer. The vibrating screen for mine uses the advanced technology and advanced self-synchronous vibrating principle at home and abroad such as vibration motor excitation, rubber spring vibration reduction, high wear-resistant material screen plate, sealing screen box, etc., and has the characteristics of long service life, low noise, high screening efficiency, etc., and is suitable for a vibrating screening device for sinter, natural ore, coke and other powdery materials.

When the existing mining machinery vibrating screen is used, excitation treatment is carried out through the vibrating motor, ore screening treatment is achieved, the vibrating motor can carry out linkage treatment through the belt, so that the motor can be synchronous, energy conservation is achieved, and the productivity is improved.

According to the mining machinery vibrating screen provided by the Chinese patent public number CN215465927U, although the protective cover is arranged above the vibrating motor, dust is effectively reduced and accumulated on the inner side of the protective cover, and meanwhile, the side surface of the linkage wheel for belt linkage is provided with the protective edge, so that the problem that the linkage wheel falls off in the rotating process is effectively prevented, but the device cannot screen ores which are aggregated together.

To this end, we propose a vibrating screen for mining machinery to solve the above-mentioned problems.
