Abstract
The utility model discloses a supporting and beating device for a screen face of a vibrating screen, and belongs to the field of vibration screening machines. The supporting and beating device solves the difficult problems that a screen face of a vibrating screen is low in vibration strength, holes are blocked by materials and the screen passing rate is low. The supporting and beating device is mainly composed of a screen box, the screen face and a beating device. According to the beating device, a plurality of supporting and vibrating shafts which make contact with the screen face are arranged below the screen face, and the two ends of each supporting and vibrating shaft are fixed to two lateral plates or lateral plate accessories of the screen box through elastic supporting bases. An adjusting device which enables the elastic supporting bases and the supporting and vibrating shafts to move in the direction perpendicular to the screen face is arranged near the elastic supporting bases, and therefore the tightness degree states of contact between the supporting and vibrating shafts and the screen face can be adjusted. A layer of elastic abrasion-resistant materials is arranged on the surface of each supporting and vibrating shaft. Materials in screen holes can be effectively removed, the screening efficiency is improved, and meanwhile, the vibrating screen has the advantages of being high in reliability, long in service life and the like. In addition, the supporting and beating device of the screen face also plays a role in supporting the screen face and the materials, and is suitable for being installed on various vibrating screens.
Description
Technical field
The utility model belongs to vibration screening machinery field, and the oscillating screen of the difficult problem such as be mainly that the compass screen surface oscillation intensity of vibratory sieve is little in order to solve, material plug-hole, screening percentage are low supports knocking device.
Background technology
Vibratory sieve is the screening to material by the compass screen surface vibration realizing on screen box and screen box, and oscillation intensity is larger, and its screening effect is better, but excessive oscillation intensity can make shorten the service life of vibratory sieve, occurs earlier period damage.So existing vibratory sieve, is limited by rigidity, intensity and service life, its oscillation intensity is generally between 3-5g.If improve screening efficiency and the disposal ability of vibratory sieve, in the situation that not increasing vibratory sieve specification, just need to improve rigidity and the oscillation intensity of Structure of Vibrating Screen.Desirable screening plant is that sieve nest moves under lower inertia force, and compass screen surface vibrates under high oscillation intensity.
Summary of the invention
The purpose of this utility model is to provide a kind of oscillating screen and supports knocking device, and this device can make the sieve nest of vibratory sieve under lower oscillation intensity, and compass screen surface obtains higher oscillation intensity, effectively removes and is stuck in the material in sieve aperture, improves screening efficiency.
The utility model is realized by following measures, mainly by screen box, compass screen surface and knocking device, formed, it is characterized in that: described knocking device is below compass screen surface, to be provided with a plurality of support rapping shafts that contact with compass screen surface, each two ends of supporting rapping shaft is fixed on two side plates or side plate annex of screen box by elastic support, described near elastic support, be provided with and can make elastic support and support the adjusting device of rapping shaft at vertical compass screen surface direction top offset, can adjust the degree of tightness state that rapping shaft contacts with compass screen surface that supports.Noise and the wearing and tearing of while supporting rapping shaft vibration in order eliminating, to clash into compass screen surface and to produce, be provided with one deck elastic abrasion-proof material on the surface of support rapping shaft.Elastic support is comprised of metal-coating, elastic rubbery body and inner metal sleeve, and elastic rubbery body is between metal-coating and inner metal sleeve.
The beneficial effects of the utility model are, oscillating screen supports knocking device, in the sieve nest vibration with vibratory sieve, support rapping shaft and can produce secondary vibration, ceaselessly beat compass screen surface, amplitude and the oscillation intensity of amplification compass screen surface, can make sieve nest under lower oscillation intensity, and compass screen surface obtains higher oscillation intensity.Effectively remove and be stuck in the material in sieve aperture, improve screening efficiency, screen(ing) machine has the features such as reliability is high, long service life simultaneously.This compass screen surface supports knocking device and also plays the effect of supporting compass screen surface and material in addition, is applicable to be arranged on various vibratory sieves.
