Background technique
Current existing flip flop screen type has Liwell type flip flop screen and vibration flip flop screen.Two types flip flop screen all includes
Two screen frames, structure is complicated, not easy to repair.Liwell type flip flop screen uses crank connecting link as driving part, and master uses between floating screen frame
Flat spring connection, this can lead to the problem of both sides, and one side flat spring does periodic wobble for a long time, easily causes the tired of flat spring
Labor is destroyed, and reduces the reliability that sieve uses, and this flat spring price is more expensive, improves the manufacturing cost of screen(ing) machine.Vibration
It is connected between dynamic flip flop screen master, floating screen frame with shear spring, using vibration excitor driving active screen frame and then drives floating screen frame vibration, though
So solve the problems, such as that elastic plate spring supporting is brought, but shear spring is easy to tear damage, when there is a spring tearing, such as
Fruit fails to find in time, then can generate chain effect, lead to other springs further tearing in a short time, reduces sieve use
Reliability.Shear spring rigidity is influenced by environmental temperature, and vibration flip flop screen is caused to be unable to steady operation.
To sum up, there is the disadvantages of structure is complicated, and parts reliability is low, and part manufacturing cost is high in existing flip flop screen.
Summary of the invention
The purpose of the utility model is to provide a kind of rod spring formula flip flop screen, to solve above-mentioned of the existing technology ask
Topic has the advantage that using novel link type spring, has stronger reliability；Using driven by vibrating motors, reliability
Stronger, manufacturing process and structure are all simpler；Floating and active screen frame different from traditional flip flop screen, its only one screen frame
(1), structure is simple, high reliablity, facilitates maintenance；The elastic parts of link-type spring (3) is fixed on the adjustable of adjustable-angle
On support frame (4), sieve is made to have the function of adjustable inclination angle, is adapted to different operating conditions；Adjustable supporter (4) itself has one
Determine quality and lower section installation isolation spring (6), support frame is made to become a natural vibration isolation frame, effectively reduces the dynamic of vibrating screen
Load.

The variation of sample does opposite or movement of supporting or opposing, so that the flexible sieve plate (12) being mounted above be made to do tension and relaxation movement.Material exists in this way
Trampolining is done on the compass screen surface of tension and relaxation, realizes layering and thoroughly sieved journey.
The utility model achieves following advantageous effects compared with the existing technology:
Using novel link type spring (3), not only there is stronger reliability, but also the structure simplified, only one
Screen frame (1) can realize the tension and relaxation of compass screen surface, and structure is simple, high reliablity, facilitate maintenance.It is driven using vibrating motor (2), it can
Stronger by property, manufacturing process and structure are all simpler.The connecting rod of rod spring (3) is forced to do by the up-down vibration of screen frame (1)
Rocker motion, and then floating beam (9) movement is driven, so that the flexible sieve plate (12) being mounted on floating beam (9) is generated tension and relaxation.Material
Biggish acceleration can be obtained on the flexible sieve plate (12) of tension and relaxation, it is preferable to complete layering sieved journey thoroughly.Link-type spring (3)
Elastic module be fixed on adjustable supporter (4), so that sieve is had the function of adjustable inclination angle, be adapted to different operating conditions.It can
It adjusts support frame (4) that itself there is certain mass and lower section installation isolation spring (6), support frame is made to become a natural vibration isolation
Frame effectively reduces the dynamic load of vibrating screen.
