The specific embodiment
Be shown one of specific embodiment of the utility model as Fig. 1, Fig. 2.This kind self-cleaning screen cloth, its grating are many one end are perpendicular to roof beam structure and be fixed on the roof beam structure 1 by setting the elastic metallic rods that spacing be arranged in parallel that the other end is free state; Roof beam structure is arranged in parallel by the beam distance of setting and the inclination angle of setting, and its two ends are fixed on the side plate 4; Side plate 4 gives fastening the connection with the vibrating sieving machine body by securing member.The quantity of described grating can decide according to the inboard width of screen cloth, the diameter of grating, the factors such as parallel distance between adjacent grating; The hole that the inclination angle of roof beam structure 1 can be kept somewhere by grating front end and last roof beam structure according to largest block in the material smoothly by and the condition that is not blocked decide.Its main feature is: described grating is divided into moving grating 3 and quiet grating 2, moving grating 3 is provided with at interval with quiet grating 2, the free end head of described moving grating 3 in same screen cloth or for straight for the band elbow or for be fixed with the pouring weight of certain mass in the elbow bottom; Quiet grating is straight rod; Moving grating on diameter, set difference with adjacent quiet grating or length different.Present embodiment Fig. 1, Fig. 2 from left to right first row be provided with the free end head band elbow of adjacent moving grating and the identical and moving grating 3 of quiet grating diameter; Second and third row is provided with the free end head band elbow of adjacent moving grating and the different and moving gratings 3 of quiet grating 2 diameters and is provided with the pouring weight of certain mass in its underpart.When finishing the assembling of this screen cloth on the vibratory sieve body on request, vibratory sieve is after the vibrating motor exciting drives, screen cloth is random vibration also, because above-mentioned technical characterictic, caused adjacent grating secondary vibration amplitude to have difference, mesh is changed in certain amplitude, and obviously the moving grating 3 bigger with respect to the Oscillation Amplitude of quiet grating 2 plays a part attack jam particle, thereby reaches in screening the effect to jam particle self-cleaning.
Be illustrated in figure 3 as two of specific embodiment of the utility model.One of this kind self-cleaning screen cloth and embodiment institute difference is, the length difference of adjacent grating, and long is moving grating 3, short is quiet grating 2.The free end head of described moving grating 3 is equipped with elbow, and with a plurality of yoke plates 6 with certain mass and length the moving grating more than two is connected to form moving grating group section in the elbow; The free end of quiet grating 2 or for straight or for the band elbow or by a yoke plate 5 elbow of many quiet gratings is connected to form quiet grating group section.
When the vibratory sieve body drives the screen cloth vibration, the secondary vibration of moving grating yoke plate group section obviously is greater than the secondary vibration that quiet grating yoke plate group section is produced, because the grating group section of many interlocks also makes the elasticity dynamics of its secondary vibration strengthen, when the elasticity dynamics of its secondary vibration during greater than the jam resistance of jam particle, can eject or make it sieve to the particle of jam mesh effectively, reach the self clean-up action of screening process, and eliminated the easy phenomenon of sticking up rod that produces of single grating.
Be illustrated in figure 4 as three of specific embodiment of the utility model.This kind self-cleaning screen cloth and the foregoing description institute difference are that the free end head of described moving grating 3 all is provided with elbow, and are connected by a plurality of yoke plates 6 with certain mass and width, thickness, length; Quiet grating 2 is straight rod, and the yoke plate of the moving grating termination of its length is long, and with above the moving grating yoke plate 6 the setting spacing is arranged.
When the vibratory sieve body drives the screen cloth vibration, the elastic vibration dynamics and the Oscillation Amplitude of moving grating yoke plate group section all can increase, spaced apart quiet grating 2 is the straight bar of holding in both hands, and the yoke plate 6 of moving grating 3 terminations of its length is long, and leaves to determining deviation below the rod with above the moving grating yoke plate 6.Because the yoke plate group section of the tool certain mass that is provided with in moving grating termination, the elasticity dynamics and the amplitude of the secondary vibration that is produced in random vibration all will increase, between its Oscillation Amplitude is greater than moving grating yoke plate and quiet grating apart from the time, the connecting plate of moving grating group section will impact the free end head of quiet grating 2, making quiet grating also be subjected to moving bar yoke plate in the moment of random vibration impacts and produces forced vibration, it is more violent that its result changes sieve aperture, cleaning effect to critical particle jam mesh is more effective, and the bonding that makes wet sticking thing is easier shakes off, and the self-cleaning effect is significant effective more.
