Description
Technical field
The invention belongs to vibration screening machinery field, is directed primarily to belt restraining rotating shaft, amplitude alternation arching trajectory
Horizontal shimmy sieve.
Background technology
In vibratory sieve application in the prior art, mainly there are straight-line trajectory, circular motion track by movement locus classification
With three kinds of elliptical trajectory, the vibratory sieve of these three forms has played huge effect in vibrosieve field.And have one
A little materials are unsuitable for the screening of this form of the above, such as the powdery in field or the granular material such as medicine, feed and rubber,
The mode of similar artificial screening motion is needed to be sieved.Existing swinging screen is usually planar circumferential movement locus, there is
It is complicated, discharging is difficult, makes and the problems such as installation accuracy is high and power demand is big.And there is also knot for crank connecting link reciprocating screen
Structure complexity and the relatively low deficiency of production efficiency.
The content of the invention
It is an object of the invention to provide a kind of horizontal shimmy sieve of arching trajectory, the shimmy sieve is with less power and light
Structure, the screening to material is realized, be adapted the distribution of material in the oscillation intensity and compass screen surface of screen(ing) machine, more than same specification screen(ing) machine
Disposal ability.
The present invention is achieved by the following measures, mainly by screen box, compass screen surface, vibrator, vibration damping support device and base
Composition, it is characterized in that：Vibrator is arranged on the feeding end of screen box, and the two sides of screen box feeding end pass through vibration damping support device and bottom
Pillar connection on seat, screen box are contacted by transverse-roller with the roller supporting plate on pillar simultaneously；The discharge end of screen box passes through bullet
Property plate or connecting plate be hinged with the vertical spindle seat being fixed on base, the length of elastic plate or connecting plate is less than the length of screen box
Degree.Described vibrator is single shaft vibrator or Double-axle vibrator, and the vibration shaft centre line of single shaft vibrator is with being located on base
Vertical spindle seat axial line in the same plane；Plane is with being located at bottom where two vibration shaft centre lines of Double-axle vibrator
The axial line of vertical spindle seat on seat is in approximately the same plane, the center of gravity and screen box pan feeding of the lengthwise position of vibrator in screen box
Between end.The connection of vertical spindle and axle bed on vertical spindle seat can be slidably connected or roll connection, vertical spindle
Center line can be perpendicular to compass screen surface.Described elastic plate or connecting plate can be elastic rod or connecting rod.
When vibratory sieve works, vibrator drives screen box vibration, realizes the screening to material.Because the discharge end of screen box passes through
Elastic plate is hinged with the vertical spindle seat on base, so the constraint of screen box vertical spindle seat and vibration damping support device on base
Under, realize that the swing of the transverse reciprocating centered on vertical spindle is vibrated by the transverse-roller of screen box both sides, the track of motion
For arc.The amplitude of motion is distributed from feeding end to discharge end with the state successively decreased, and the curve of vibration is bent in the sine of decay
Line.The size of screen box discharge end amplitude is relevant with the elasticity of elastic plate.Because material is in spring up on the compass screen surface of shimmy sieve
State motion, so the inclination angle of compass screen surface needs to be more than or equal to 20 °.
Because the amplitude of vibration successively decreases, the material on compass screen surface gradually decreases, so the height of sieve box side plate can
To be gradually to reduce, i.e., the height of discharge end sieve box side plate is less than the height of feeding end sieve box side plate, and the ginseng for reducing screen(ing) machine is shaken
Weight.
Width before and after the screen box of existing vibratory sieve is the same, because the material on compass screen surface is gradual in screening process
Reduce, so the utilization rate of discharge end compass screen surface is with regard to relatively low.The screen box of the application can be the trapezoidal shape that feeding end is wide, discharge end is narrow
Shape, the width of compass screen surface by width to narrow, i.e. width of the width of discharge end screen box less than feeding end screen box.With the successively decreasing of amplitude,
The reduction of material, compass screen surface are also gradually reduced on compass screen surface.Also it can suitably widen the width of screen box feeding end, reduce the width of discharge end
Degree, the power and compass screen surface of screen(ing) machine are made full use of, improve production efficiency.Material on feeding end compass screen surface is more, the bed of material is thick, just widens sieve
Face, discharge end material is few, and the bed of material is thin, with regard to constriction compass screen surface.On the premise of production capacity is ensured, make the overall dimensions and again of screen(ing) machine
Amount reduces, and reaches the effect for saving the energy.
The invention has the advantages that because the vibrator of vibratory sieve is arranged on the feeding end of screen box, its large amplitude and big
The big thickness of feed layer of oscillation intensity and screen box feeding end be just adapted, be advantageous to sieve, effectively raise the efficiency of screening.
When material is moved to the discharge end of screen box, material greatly reduces, and the amplitude of screen box also reduces.With less oscillation intensity, reach
To the disposal ability of same specification vibratory sieve.Because the discharge end of screen box is hinged by elastic plate and the vertical spindle seat on base,
The stability of vibratory sieve is improved, and more and few influence to screen box vibration of material also greatly reduces.Also greatly simultaneously
Destructive power of the covibration to screen(ing) machine when reducing start or shutdown.The shimmy sieve effectively simulates the principle manually sieved,
The force action line of vibrator by the center of gravity of screen box, need not be such that the oscillation intensity of screen(ing) machine is mutually fitted with the distribution of material on compass screen surface
Should.Have the characteristics that simple in construction, service life is long and easy to maintenance, suitable for chemical industry, food, medicine, feed, plastics, rubber
Screening and classification of the industries such as glue, wood industry and metallurgy to fine powder and microgranular material.
