Abstract
The invention discloses a vibrating screen, which comprises a screen box, a screen sieve and supports, wherein the supports are provided with position regulation holes, and the supports are connected to the screen sieve through the position regulation holes; at least two position regulation holes and two supports are arranged; the supports are located at the two sides of the screen box; the position regulation holes are through holes; a rubber sleeve or a plastic sleeve is arranged in each through hole; great vibration will be produced when the vibrating screen works, such design enables the through holes and the screen sieve to be connected more stably. The angle of the screen sieve can be adjusted more flexibly, besides, the structure is simple, the operation is convenient and the cost is low.
Description
Technical field
The present invention relates to a kind of vibratory sieve.
Background technology
Vibratory sieve is to utilize the reciprocating rotary type that oscillator exciting produces vibrate and work.The upper rotation weight of oscillator makes compass screen surface produce plane whirling vibration, and lower rotation weight makes compass screen surface produce conical surface rotary vibration, and its symphyogenetic effect makes compass screen surface generation revolve again type vibration.Its oscillation trajectory is the space curve of a complexity.This curve is projected as a circle at horizontal plane, and is projected as an ellipse on vertical plane.Regulate the exciting force of upper and lower rotation weight, can change amplitude.And regulate the space phase angle of upper and lower weight, can change the curve shape of compass screen surface movement locus and change the movement locus of material on compass screen surface.
Existing screen cloth and horizontal sextant angle are generally all fixed, and are difficult for adjusting, and screening effect is under some influence, and is unfavorable for different material to screen.Meanwhile, while work due to vibratory sieve, produce a large amount of dust and be unfavorable for operation, affect operator's health.
In Chinese Patent Application No.: disclose a kind of vibratory sieve in 200910127524, three vibrators connect into two rectangular configuration on limits altogether by longeron, and compass screen surface is arranged in rectangular configuration, and rectangular configuration is connected by spring with frame.When work, rectangular configuration vibration and side plate does not vibrate.Compass screen surface can be that single hop can be also multistage combination, and amplitude, vibration frequency, vibrating deflection and the oscillation trajectory of each section of compass screen surface can both independently regulate, to the strong adaptability of different screening materials carryings.This technical scheme complex structure, operation inconvenience, cost is high.
In Chinese Patent Application No.: disclose a kind of adjustable vibration screen in 201210227459, it comprises vibrator, sieve nest is provided with rotating beam on sieve nest, and rotating base is sleeved on rotating beam, vibrator is fixed on rotating base top, bottom at rotating base is provided with connecting plate, has hole on connecting plate, is provided with fixed head with the sieve nest of connecting plate correspondence position, on fixed head, have hole, fixed head and connecting plate are bolted to connection.This technical scheme can, according to using needs, be adjusted the angle of vibrator and sieve plate, meets the needs of screening different material; But, this technical scheme complex structure.
In Chinese Patent Application No.: disclose a kind of vibratory sieve in 201310000553.2, comprise base, screen box, one-level screen cloth, secondary screen cloth, vibrator and motor, described one-level screen cloth is positioned at the top of secondary screen cloth, one-level screen cloth becomes 17 ° of angles with horizontal plane, secondary screen cloth becomes 13 ° of angles with horizontal plane.The vibratory sieve that this technical scheme provides, changes screen cloth angle of assembling, has not only improved output, has reduced cost, has also reduced mixed storehouse rate; But clearly the angle of the screen cloth of this technical scheme is fixed, do not meet the needs to screening different material.
Summary of the invention
For the problems referred to above, the invention provides the vibratory sieve that a kind of angle can be adjusted flexibly.
In order to address the above problem, technical scheme provided by the invention is:
A kind of vibratory sieve, comprise screen box, screen cloth, also comprise support, described support is provided with position adjustments hole, described support is connected with described screen cloth by described position adjustments hole, the quantity in described position adjustments hole is at least 2, so just screen cloth can be arranged on diverse location adjustment hole, thus the angle of adjustable screen.
Preferably, described number of holders is 2.
Preferably, described support is positioned at described screen box both sides, and such design is more reasonable.
Preferably, described position adjustments hole is through hole.
Preferably, be provided with rubber sleeve or plastic sheath in described through hole, can produce very large vibration when vibratory sieve operation, to allow through hole be connected with screen cloth more stable in design like this.
Compared with prior art, beneficial effect of the present invention is: the angle of screen cloth of the present invention can be adjusted more flexibly, and simple in structure, easy to operate, and cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention 1;
Fig. 2 is the partial sectional view of the embodiment of the present invention 1 right view;
Fig. 3 is the structural representation of the embodiment of the present invention 2.
In figure: 1, screen box, 2, screen cloth, 3, support, 4, through hole, 5, rubber sleeve, 6, plastic sheath.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
Embodiment 1:
In conjunction with Fig. 1, Fig. 2, a kind of vibratory sieve of the present invention, comprise screen box 1, screen cloth 2, also comprise support 3, support 3 is provided with 2 position adjustments through holes 4, and support 3 is connected with screen cloth 2 by position adjustments through hole 4, so just screen cloth 2 can be arranged on to diverse location and regulate on through hole 4, thereby the angle of adjustable screen 2, in the present embodiment, screen cloth and horizontal sextant angle are 30 degree.It is 2 that support 3 quantity are preferably, and is positioned at screen box 1 both sides, and design is from stressed more reasonable with use angle consideration like this.In through hole 4, be provided with rubber sleeve 5, can produce very large vibration when vibratory sieve operation, design allows through hole 4 be connected more stable with screen cloth 2 like this.
Embodiment 2:
In conjunction with Fig. 3, a kind of vibratory sieve, comprise screen box 1, screen cloth 2, also comprise support 3, support 3 is provided with 3 position adjustments through holes 4, and support 3 is connected with screen cloth 2 by position adjustments through hole 4, so just screen cloth 2 can be arranged on to diverse location and regulate on through hole 4, thereby the angle of adjustable screen 2, in the present embodiment, screen cloth and horizontal sextant angle are 10 degree.It is 2 that support 3 quantity are preferably, and is positioned at screen box 1 both sides, and design is from stressed more reasonable with use angle consideration like this.In through hole 4, be provided with plastic sheath 6, can produce very large vibration when vibratory sieve operation, design allows through hole 4 be connected more stable with screen cloth 2 like this.
