Vibration screening machine

Abstract

The invention relates to a vibration screening machine which comprises a top fixing plate and a bottom plate. A motor mounting frame is fixed on the lower side of the top fixing plate, a motor is mounted inside the motor mounting frame, a stirring frame is connected to an output shaft of the motor, a plurality of stirring brushes are mounted on the lower side of the stirring frame, two guide columns are arranged on the two sides of the stirring frame, each guide column is sleeved with a lantern ring, and a screen is connected between the two lantern rings. The guide columns are fixed on the upper sides of supporting plates, the upper side of each supporting plate is provided with a vibration device, and each vibration device comprises a first air cylinder, a supporting rod and a vibrationring, wherein the top of the first air cylinder is hinged with a rotating rod, the top of the supporting rod is hinged with the rotating rod, the two sides of the vibration ring are connected with vibration ring side plates, the upper side of the vibration ring is provided with a plurality of top columns, the top columns are positioned on the lower sides of the lantern rings, guide holes are formed in the vibration ring side plates, the guide columns penetrate through the interiors of the guide holes, and the lower sides of the vibration ring side plates are connected with springs. The vibration screening machine is simple in structure, low in cost and good in screening effect.

Description

technical field [0001] The invention relates to the technical field of screening machines, in particular to a vibration screening machine. Background technique [0002] The screening machine uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and divide sand, gravel, crushed stone and other materials into different grades of vibrating screening mechanical equipment according to the particle size. The screening machine is often used in conjunction with a vibrating device during the screening process. During the vibration process, the clogged particles in the screen can be vibrated down. [0003] Most of the existing screening machines use vibration motors or other electric vibration equipment. During the process of use, the vibration will affect the entire screening machine. The noise and the vibration of the whole machine are relatively large. It is necessary to add anti-vibration devices. The over...

Problems solved by technology

[0003] Most of the existing screening machines use vibration motors or other electric vibration equipment. During the process of use, the vibration will affect the entire screening machine. The noise and the vibration of the whole machine are relatively large. It is necessary to add anti-vibration devices. The overall structure is more complicated and the cost is higher. high

In addition, the vibration motor vibrates continuously, the vibration energy is scattered, the average vibration intensity is weak, and the vibration screening effect is poor
