Description
Technical field
The utility model relates to a kind of vibrating device of vibration sieve, belongs to electromagnetic vibrating screen equipment technical field.
Background technology
At present, high frequency vibrating screen sorts field at mineral and is used widely, and the high frequency vibrating power of the 50Hz being produced by vibrator passes to screen cloth by vibrating shaft and vibration cap, makes screen cloth also do dither with identical 50Hz frequency.Vibration cap in vibrating device is unique part contacting with screen cloth, is also last parts of transmitting vibrations power, therefore vibrates cap and directly determined at the arrangement of screen cloth lower end the quality of screen(ing) machine vibrating effect.At present, each root vibrating shaft of the prior art only drives a vibration cap to impact screen cloth, screen cloth impact position oscillation intensity is high, and successively decrease to both sides, due to the contour structures restriction of vibrator, the arrangement pitch that has determined vibration cap is larger, and the vibration force that therefore has one section of screen cloth is very weak, causes the vibrating effect of screen cloth inconsistent; In addition; in actual production, be that the every fragment position that ensures screen cloth has vibration; will increase the vibration force that vibrator produces; because only having a vibration cap to concentrate, every group of beating unit impact screen cloth; so can cause catch net wearing and tearing very fast, on-the-spotly often occur that catch net is vibrated cap and impact the problem of fracture.Finally, because screen cloth is flexible screen, when a large amount of materials are in the timesharing of compass screen surface top sieve, vibration cap can play the effect of support, and because spacing is large, screen cloth subsides downwards in the position that does not vibrate cap, and stacking material affects the effective sifting area of screen cloth.
Utility model content
The utility model object is to provide a kind of vibrating device of vibration sieve, is driven and more than two or two is vibrated the vibration cap that cap form and combine to impact screen cloth by vibrating shaft, increases vibration contact area, the problem existing in solution background technology.
The technical solution of the utility model is:
A kind of vibrating device of vibration sieve, comprise the many groups of vibrating systems that are arranged in juxtaposition that are arranged on screen cloth below, every group of vibrating system comprises the combination of vibration cap, vibrator, shear spring, vibrating shaft and supporting seat, described vibration cap combination comprises two or two above vibration cap and connecting plates, more than two or two vibration caps are fixedly connected with by connecting plate, vibrating shaft is fixed on screen(ing) machine side plate by supporting seat, the spindle nose position of vibrating shaft is connected with vibrator, vibrating shaft is provided with arm plate, arm plate on vibrating shaft is connected with any vibration cap in the combination of vibration cap, vibration cap contacts with screen cloth, shear spring one end is fixed on connecting plate, the other end is fixed on screen(ing) machine side plate.
Described vibration cap is polyurethane material, and vibration cap is evenly arranged according to the length of compass screen surface.
Described supporting seat inside is provided with elastomer.
Adopt the utility model, it is upper that the high frequency vibrating power that vibrator produces is delivered to the combination of vibration cap by vibrating shaft, and vibrating shaft driving more than two or two is vibrated cap and impacted screen cloth, increases vibration contact area, thereby realize the dither of screen cloth, reach the effect of screening materials carrying.
The beneficial effects of the utility model are: improved the vibrating effect of screen cloth and the effective sifting area of screen cloth, reduced the wearing and tearing of catch net in screen cloth, realized the dither of screen cloth, improved the screening effect of screening materials carrying.

Detailed description of the invention
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, 2, 3, 4, 5, a kind of vibrating device of vibration sieve, comprise the many groups of vibrating systems that are arranged in juxtaposition that are arranged on screen cloth below, every group of vibrating system comprises vibration cap combination 3, vibrator 5, shear spring 6, vibrating shaft 8 and supporting seat 9, described vibration cap combination 3 comprises two or two above vibration cap 7 and connecting plates 10, vibration cap is polyurethane material, more than two or two vibration caps are fixedly fixed together and are formed a rigidity vibrating body by connecting plate 10, vibrating shaft 8 is fixed on screen(ing) machine side plate by supporting seat 9, supporting seat 9 is interior arranges elastomer axial restraint vibrating shaft small size axial rotation, the spindle nose position of vibrating shaft 8 is connected with vibrator 5, vibrating shaft 8 is provided with arm plate, arm plate on vibrating shaft 8 is connected with any vibration cap in vibration cap combination 3, when screen(ing) machine operating angle is during at 20 °-30 °, vibration cap combines 3 gravitates, naturally droop, now, every vibration cap fully contacts with screen(ing) machine catch net.Four groups of shear springs are suspended on screen(ing) machine inside, and shear spring 6 one end are fixed on connecting plate 10, and the other end is fixed on screen(ing) machine side plate.Every group of vibrating system driven and more than two or two vibrated cap and impact screen cloth by a vibrating shaft 8, increases vibration contact area, makes vibration force be dispersed in screen cloth below.Many group vibrating systems can be used side by side according to screen length, ensure that vibration cap is evenly arranged, and make the vibration force deviation minimum of the each position in effective working region of screen cloth.
