The three-dimensional view of exciting device 3 shown in Fig. 9, it includes main vibration spring 21, plastid 22 and vibrating motor 23.Two vibrations
Dynamic motor 23 is mounted on 22 side of plastid, and 22 other side of plastid arranges that 4 column, 4 row's main vibration spring 21 requires to select according to different-stiffness
Spring number, i.e. spring number are variable.
In the present embodiment；Tension and relaxation body 2 is made of active screen frame 12 and floating screen frame 13, and the crossbeam of two screen frames is interspersed,
Wherein active screen frame 12 is fixedly connected with outer screen frame 1.Exciting device 3 drives the outer vibration of screen frame 1 to make active screen frame 12 vibrate,
Due to being to be connected between active screen frame 12 and floating screen frame 13 with shear spring 14, vibration frequency, which is transferred to, to be made active screen frame 12 and floats
Dynamic screen frame 13 is in the size of opposite phase, so that floating screen frame 13 is generated the vibration with 12 opposite phase of active screen frame, makes to connect
Flexible sieve plate 6 on active screen frame 12 and floating screen frame 13 does tension and relaxation movement.The compass screen surface of tension and relaxation make in thereon material by
To the power perpendicular to compass screen surface, and compass screen surface is at an angle to the horizontal surface, therefore material can be tossed and travel forward.Due to exciting
Device 3 is vibrated by vibrating motor band kinetoplast 22, and plastid 22 is connect with outer screen frame 1 by main vibration spring 21, constitutes additional mass
Vibration drives macroplast vibration to reach energy-efficient purpose by small mass vibrating.Outer screen frame 1 makes along compass screen surface width direction straight-line oscillation
Overall screen face has oscillation crosswise, and power of the material in by flexible compass screen surface projectile forward movement also by compass screen surface transverse direction is rubbed
Power and side plate thrust are wiped, material loosening is activated, is conducive to material layering and sieves thoroughly.Three tension and relaxation bodies 2 respectively horizontal by
15 °, 20 °, 25 ° are mounted on tension and relaxation body quantity and setting angle on outer screen frame 1 and can require to change according to screening, make whole compass screen surface
Also in 15 °, 20 °, 25 ° of Banana Type compass screen surface, material screening with constant bed thickness is realized.
More plastid activated vibration uniform thickness flip flop screen mounting means provided by the invention are as follows:
The sieve beam interlaced arrangement of active screen frame 12 and floating screen frame 13, with shearing between active screen frame 12 and floating screen frame 13
Spring 14 connects and composes a tension and relaxation body 2.Three tension and relaxation bodies 2 are respectively horizontal by 15 °, 20 °, 25 ° of tension and relaxation body quantity and peace
Dress angle can be required to change and is mounted side by side between 1 two side plates 8 of outer screen frame according to screening, be fixedly connected with side plate 8, in side
Between staying the bolt hole of redundancy that tension and relaxation body 2 is allow to be fixedly mounted on both side plate 8 with different angle on plate 8, make compass screen surface adjustable angle.
Exciting device 3 is mounted on outer 1 side side plate 8 of screen frame, and bolt pressure is applied at 21 both ends of main vibration spring between plastid 22 and side plate 8
It fastens.Outer 1 first half of screen frame and latter half respectively install a pair of of T-type spring arrangement 5, part and side on T-type spring arrangement 5
Plate 8 is fixedly connected with bolt, is fixedly connected below with support frame 4 with bolt.Flexible 6 both sides of sieve plate are mounted on the card of tension and relaxation body 2
It is compressed in slot 18 and with press strip and constitutes entire compass screen surface.
The working principle of more plastid activated vibration uniform thickness flip flop screens provided by the invention are as follows:
Vibration device 3 drives the outer vibration of screen frame 1 to make active screen frame 12 vibrate, between active screen frame 12 and floating screen frame 13
It is to be connected with shear spring 14, excited frequency, which is transferred to, makes active screen frame 12 and floating screen frame 13 be in the size of opposite phase,
So that floating screen frame 13 is generated the vibration with 12 opposite phase of active screen frame, makes to be connected on active screen frame 12 and floating screen frame 13
Flexible sieve plate 14 does tension and relaxation movement, and the material in flexible compass screen surface is made to do trampolining.Excited frequency is transferred to exciting device 3 to shake
Width is smaller, the biggish frequency operating points of amplitude of screen box, so that the vibration of plastid 22 is driven screen frame vibration, reaches the mesh for making device energy conservation
, and since the vibration of plastid 22 that vibrating motor 23 connects is smaller, also function to the effect of protection motor.Exciting device 3
Exciting force by screen box mass center, exciting force is oriented parallel to ground and screen(ing) machine width direction, perpendicular to material movement direction, makes
Screen box is also vibrated in this direction reciprocating linear, makes material not only by the throwing power perpendicular to compass screen surface, also by compass screen surface and material
Between or the side-friction between material and material and side plate lateral thrust, activate material sufficiently loosely.Due to compass screen surface
The segmented Banana Type compass screen surface being made of tension and relaxation body 2, therefore material quickly moves on the compass screen surface of feeding end larger angle, makes
Supplied materials is quickly spread out, and material tails off after one section of screening, and movement velocity reduces on the compass screen surface of discharge end smaller angle, is kept
Thickness of feed layer originally realizes the screening with constant bed thickness from feeding end to discharge end on the whole in this way.Due to using multiple tension and relaxation bodies 2
It is combined into the compass screen surface of a blocking, single sieve plate 6 can be shorter, is conducive to the modular repair of compass screen surface, and blocking is each
A tension and relaxation body 2 using the shear spring 14 with different-stiffness different number, can be such that the master of each tension and relaxation body 2, floating screen frame has not
Same relative amplitude, can thus make every section of compass screen surface being made of tension and relaxation body 2 have different oscillation intensities, feeding end makes its vibration
Fatigue resistance ambassador's material fast hierarchical makes its oscillation intensity smaller residence time for extending material on compass screen surface, shape in discharge end
At significantly more efficient screening.
Invention applies a specific example illustrates the principle and implementation of the invention, above embodiments are said
It is bright to be merely used to help understand method and its core concept of the invention；At the same time, for those skilled in the art, foundation
Thought of the invention, there will be changes in the specific implementation manner and application range.To sum up, the content of the present specification should not manage
Solution is limitation of the present invention.
