Abstract
The utility model provides a vibrating sieve which comprises a sieve mesh body, a vibrating power device and a vibrating mechanism. The sieve mesh body is provided with one or more layers of sieve meshes with different aperture, the vibrating power device is arranged on a machine frame and drives the sieve mesh body to vibrate, and the vibrating mechanism is arranged between the sieve mesh body and the machine frame. The vibrating sieve is characterized in that the vibrating mechanism is composed of permanent-magnetic bodies which are arranged between the machine frame and the sieve mesh body,and the same poles of the permanent-magnetic bodies are opposite. Compared with the prior art, the vibrating sieve has the advantages of easily adjusting the vibrating frequency and amplitude and having low noise.
Description
Technical field:
The utility model relates to a kind of screening plant.
Background technology:
Existing reciprocating sieve generally is to be made of the screen cloth body of the screen cloth that has layer or above different apertures, the vibrations power set that drive the vibrations of screen cloth body, the vibrations spring mechanism that is arranged between screen cloth body and frame, and the vibration frequency of screen cloth body is by comprising that the whole system that shakes spring mechanism is determined.During use, when the vibration frequency of needs change reciprocating sieve or amplitude, generally realize by changing the vibrations spring mechanism, and the vibrations spring mechanism is fixed on screen cloth body and the frame by fastening means, so just bring very big inconvenience to the user, and, because the vibrations spring mechanism is a kind of mechanical shock mechanism of contact, be easy to generate very big noise pollution surrounding environment.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of easy adjusting vibration frequency and reciprocating sieve amplitude, that noise is little.
The utility model is to realize like this, comprise by the screen cloth body of the screen cloth that has one deck or above different apertures, the vibrations power set that drive the vibrations of screen cloth body, the percussion mechanism that is arranged between screen cloth body and frame constituting that its special feature is that percussion mechanism is made of the homopolarity permanent magnet opposed that is arranged between frame and screen cloth body.During work, because the permanent magnet homopolarity is relative, two permanent magnets are spaced from each other under the effect of homopolar-repulsion, and, along with two permanent magnets lean on closely more, repulsive force is big more, under the acting in conjunction of vibrations power set, make the screen cloth body with certain frequency vibrations, and vibration frequency to be magnetic force size by two permanent magnets determined, when needing to change vibration frequency, only need to change two different permanent magnets of magnetic attraction to get final product, therefore, the adjusting vibration frequency is more convenient, during vibrations, because two permanent magnets are not in contact with one another, like this, just can not produce the sound of mechanical collision.
Here, percussion mechanism is arranged between four angles and frame of screen cloth body.
Therefore the utility model, has advantage easy adjusting vibration frequency and amplitude, that noise is little owing to adopted two permanent magnets that homopolarity is oppositely arranged as percussion mechanism.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model comprises by the screen cloth body 1 of the screen cloth that has one deck or above different apertures, the vibrations power set 2 that are arranged on drive screen cloth body 1 vibrations on the frame 3, the percussion mechanism 4 that is arranged on 3 of screen cloth body 1 and frames and constituting that its special feature is that percussion mechanism 4 is made of the homopolarity permanent magnet opposed 5 that is arranged on 1 of frame 3 and screen cloth body.At screen cloth body 1 and 3 of frames non-magnetic conduction sleeve 6 and non-magnetic conduction guide pillar 7 are set, two permanent magnets 5 that homopolarity is relative are separately positioned in the non-magnetic conduction sleeve 6 and on the non-magnetic conduction guide pillar 7, and the effect of non-magnetic conduction sleeve 6 and non-magnetic conduction guide pillar 7 is that screen cloth body 1 is positioned on the frame 3.Percussion mechanism 4 is arranged on 3 of four angles of screen cloth body 1 and frames together with non-magnetic conduction sleeve 6 and non-magnetic conduction guide pillar 7.
Claims (3)
1, a kind of reciprocating sieve, comprise by the screen cloth body of the screen cloth that has one deck or above different apertures, the vibrations power set that are arranged on the drive screen cloth body vibrations on the frame, the percussion mechanism that is arranged between screen cloth body and frame constituting, it is characterized in that percussion mechanism is made of the homopolarity permanent magnet opposed that is arranged between frame and screen cloth body.
2, reciprocating sieve according to claim 1 is characterized in that being provided with non-magnetic conduction sleeve and non-magnetic conduction guide pillar between screen cloth body and frame, two permanent magnets that homopolarity is relative be separately positioned in the non-magnetic conduction sleeve and non-magnetic conduction guide pillar on.
