Compass screen surface generates again rotation type and vibrates.Its oscillation trajectory is a complicated space curve.The curve is projected as a circle in horizontal plane, and
On the vertical plane be projected as one ellipse.Adjust the exciting force of upper and lower rotation weight, thus it is possible to vary amplitude.And it adjusts upper and lower
The space phase angle of weight then can change the curve shape of compass screen surface motion profile and change the motion profile of material on compass screen surface.
Vibrating screen is broadly divided into linear vibrating screen, circular shale shaker, high frequency shale shaker.Vibrating screen can be divided into uniaxial vibration by the pattern of vibrator
Dynamic sieve and dual-axis vibration sieve.Single-shaft vibrating screen is to vibrate screen box using single unbalanced weight exciting, compass screen surface inclination, the movement of screen box
Track is generally circular in cross section or oval.Dual-axis vibration sieve is using the double unbalanced weight excitings for synchronizing incorgruous revolution, and compass screen surface is horizontal
Or low-angle dip, the motion profile of screen box are straight line.Vibrating screen have inertia vibrating screen, eccentric vibrating screen, self-fixed centre shale shaker and
The types such as hummer screen.
For vibrating screen on the market there is various problems, the material that vibrating screen is selected is easy the sieve of blocking discharge port at present
Net, and when vibrating screen charging, in the case that charging is excessive, material is easy to block feed inlet.
Utility model content
The purpose of the utility model is to overcome defects existing in the prior art, provide a kind of compound vibrating screen, by two
A vibrating screen is combined into one, and material is divided into two parts and enters in vibrating screen while being screened when charging, greatly improves efficiency
And it not will cause feed blocking phenomenon.
To achieve the above object, the technical solution of the utility model is there is provided a kind of compound vibrating screen, including screen box, sets
The sieve nest component being placed in the screen box, the sieve nest component includes sieve nest rack, the upper layer that is set in the sieve nest rack
Screen assemblies and lower screen component, screen box inner wall two sides are provided with several support plates, and sieve nest rack two sides are set
Several support legs are equipped with, elastomeric element is provided between the support plate and the support leg, the sieve nest rack passes through described
Support leg is matched with the support plate and is set up in the screen box, and the driving sieve nest rack is provided in the sieve nest rack
The exciting component of screen box vibration relatively offers material inlet on the screen box, is provided at the material inlet by object
Material imports the stock guide of the upper screen component, material is imported to the material guide channel of the lower screen component.
Further improved to be: the upper screen component and the lower screen component include several layer stackups
Sieve.
Further improved to be: the upper screen component and the lower screen component include the sieve of trilaminate stack
Net.
Further improved to be: the stock guide is obliquely installed, and the material guide channel is vertically arranged.
Further improved to be: the elastomeric element is spring.
Further improved to be: the exciting component is vibrating motor.
Further improved to be: the exciting component is set to the top of the sieve nest rack.
Further improved to be: the sieve nest rack includes the side plate for being located at two sides, is connected between side plate described in two sides
Several support rods for being used to support sieve.
Further improved to be: the sieve mutually dismantles setting with the rack.
Advantages and beneficial effects of the utility model lie in that it is low successively to sieve easy bridging efficiency for sieve in the prior art
Under, design is improved to feed inlet, is carried out a vibrating screen as two sieve nests using material a part passes through upper sieve
Screen component is sieved, and another part material is sieved by lower screen component, is not only greatly improved the efficiency, but also not
It will cause blocking phenomenon.
