Description
Technical field
The utility model is related to sieving machine technical field, more particularly to a kind of single-shaft vibrating screen.
Background technology
Vibratory sieve is a kind of efficient screening plant, is widely used in the fields such as mining, metallurgy, hydraulic and electric engineering, building.Shake
Dynamic sieve is typically made up of sieve nest, vibrator and motor, and motor drives vibrator main axis, the uneven counterweight institute on vibrator
Under the centrifugal intertia force effect of generation, driving sieve nest is vibrated.Vibratory sieve is by the different granular thing of granular size when working
Expect group, the single or multiple lift compass screen surface of the uniform cloth hole of multipass is divided into the process of some different stages as screening.More than sieve aperture
Particle stay on compass screen surface, be referred to as the oversize of the compass screen surface, the particle less than sieve aperture passes through sieve aperture, under the sieve for being referred to as the compass screen surface
Thing.The granular material that a large amount of granule sizes are different, thickness mixes enters after compass screen surface, and only a part of particle is contacted with compass screen surface, by
In the vibration of sieve nest, the oversize bed of material is loose, is further enlarged the gap that bulky grain is natively present, little particle is seized the opportunity
Through gap, it is transferred on lower floor or transporter.Because little particle gap is small, bulky grain can not be passed through, then original mixed and disorderly
The particle swarm arranged without chapter is separated, i.e., be layered by granular size, form little particle under, on coarse granule residence
Queueing discipline, reach the fine grained of compass screen surface, sieved thoroughly less than sieve aperture person, finally realize thick, fines segregation, complete to be sieving through
Journey.
Utility model content
The purpose of this utility model is to provide that a kind of simple in construction, screening is uniform, the preferable single shaft of overall construction intensity shakes
Dynamic sieve.
In order to solve the above technical problems, the utility model employs following technical scheme：
A kind of single-shaft vibrating screen, including base, the sieve leg that is arranged on base and by sieving the sieve nest that leg is supported, the sieve
Body is provided centrally with central tube and eccentric shaft, the centrally disposed pipe of eccentric shaft, and swivel bearing, eccentric shaft are provided with eccentric shaft
One end is connected with drive, and the other end is connected with rear and front end difference on flying wheel, drive connection motor, the sieve nest
Be provided with support bar, support bar two ends are stretched out from sieve nest both sides respectively, support bar two ends are respectively arranged with support base, support bar with
It is fixedly connected between support base, support base is separately positioned on sieve leg, spring is provided between support base and sieve leg.
In above-mentioned technical proposal, further, the support bar uses hollow pipe, is internally provided with and adds at support bar two ends
Strong bar, is interference fit between bracing piece and support bar, bracing piece is extended in sieve nest along support bar rod end.
In above-mentioned technical proposal, further, the swivel bearing is separately positioned in bearing block, and bearing block is fixedly mounted
On the sieve nest at central tube two ends, swivel bearing both sides are provided with oil scraper ring.
The utility model uses eccentric shaft to provide exciting force for vibratory sieve, and sieve nest is propped up by support base and spring
Support, vibratory sieve screening is uniform；Eccentric shaft formation is effectively protected in the centrally disposed pipe of eccentric shaft, the rotation at eccentric shaft two ends
Rotating shaft holds both sides and sets oil scraper ring, can reduce the consumption of lubrication butter, and can prevent butter from entering in central tube, and influence is eccentric
The operation of axle.
