Description

A mechanical spring vibrating screen with rack and gear meshing limit type

technical field

The utility model relates to a vibrating screen, in particular to a mechanical spring vibrating screen of rack and gear engagement limit type, which belongs to the technical field of mechanical equipment.

Background technique

The vibrating screen works by using the reciprocating rotary vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to generate plane circular vibration, while the lower rotating weight causes the screen surface to generate conical rotary vibration. The effect is to make the screen surface produce reciprocating vibration. Its vibration track is a complex space curve, which is projected as a circle on the horizontal plane, and projected on the vertical plane as an ellipse. Adjusting the excitation force of the upper and lower rotating weights can change the vibration amplitude; and adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the motion track of the screen surface and change the motion track of the material on the screen surface.

Vibrating screens are mainly divided into linear vibrating screens, circular vibrating screens, and high-frequency vibrating screens. Vibrating screens can be divided into single-shaft vibrating screens and double-shaft vibrating screens according to the type of vibrator. The single-axis vibrating screen uses a single unbalanced weight to vibrate the screen box, the screen surface is inclined, and the motion track of the screen box is generally circular or elliptical. The double-axis vibrating screen is excited by double unbalanced weights that rotate in different directions synchronously. The screen surface is horizontal or gently inclined, and the motion track of the screen box is a straight line. Vibrating screens include inertial vibrating screens, eccentric vibrating screens, self-centering vibrating screens and electromagnetic vibrating screens.

However, the existing vibrating screens are generally driven by electric motors and have a complex structure; at the same time, there is no peripheral limit for the box of the vibrating screen, resulting in exposed connecting parts, which affects the appearance and safety.
