Abstract
The utility model provides a technical proposal, mainly comprising a plurality of beams and a plurality of screen strips, which is characterized in that: a plurality of frequency conversion boards are fixed in each screen strip of a screen and on chosen screen strips in interval; the frequency conversion boards are arranged at the bottom of the screen strips and positioned at the front-middle part of the screen strips; the chosen screen strips in interval indicates that a screen strip for fixing the boards is chosen between each screen strip; each board can be a rectangle metal plate. The fixed oscillation frequency of the screen strips of the boards leads different fixed oscillation frequency of two adjacent screen strips, so vibration of two screen strips is not synchronous in operation; when viscous and dense material is adhibited on the screen strips, friction of screened material between two screen strips is caused by the non-synchronous vibration of two screen strips. The utility model has the advantages that: the material adhibited on the screen strips is released because of friction, so the screen strips can not be adhibited with the material when screened; in addition, wedge-shaped material falls into screen holes for convenient discharging, ensuring the screening efficiency and precision of the screen.
Description
Affiliated technical field:
The utility model relates to a kind of at the industrial vibratory sieve that is used to sieve material, especially a kind of Cantilevered screen.
Background technology:
In the prior art, known Cantilevered screen all is to be made of crossbeam and a plurality of gratings that are inserted on the crossbeam, the screen cloth of this structure, when the bigger material of screening stickiness, the granular material that is sized in the material will be sticky on the grating, makes grating chap gradually, and two adjacent gratings are connected, make screen cloth lose screening efficiency and screening precision, this is to be used to sieve the existing maximum disadvantage of stickiness material in the prior art.
Summary of the invention:
The utility model is at the existing in prior technology deficiency, and a kind of Cantilevered screen technical scheme at screening stickiness material is provided.
This programme is realized by following technical measures: mainly include crossbeam and grating, the characteristics of this programme are in each grating of screen cloth, on the grating of choosing, are fixed with the frequency conversion plate at interval, described frequency conversion plate is the bottom surface at grating, is positioned at the middle front part of grating.The concrete grating of choosing at interval is meant every a grating and just chooses the fixedly grating of frequency conversion plate of need.And described frequency conversion plate can be a rectangle metallic plate.
The beneficial effect of this programme can be learnt according to the narration to such scheme, in the grating owing to screen cloth in this scheme, between be separated with the fixedly grating of frequency conversion plate, this is fixed with the natural mode shape of frequency conversion plate grating, and just the natural mode shape with two adjacent gratings is different, because the frequency of oscillation difference of adjacent grating, the vibration of grating just can not be synchronous when work, when the stickiness material is sticky on the grating, because of the nonsynchronous vibration of adjacent grating, the material that is sized will produce friction between two gratings, the material that is sticky on the grating is come off by friction, thereby when having guaranteed screening stickiness material, grating can be sticking not glutinous by material, is convenient in addition discharge when the wedge shape material falls into sieve aperture, and the screening efficiency of screen cloth and screening precision are guaranteed.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the part sectional structure schematic diagram of the utility model specific embodiment.
Fig. 2 is the structural representation of looking up of Fig. 1.
1 is crossbeam among the figure, and 2 is grating, and 3 are the frequency conversion plate.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, the Cantilevered screen of this programme, mainly include crossbeam (1) and grating (2), the characteristics of this programme are in each grating (2) of screen cloth, at interval on the grating of choosing (2), be fixed with frequency conversion plate (3), described frequency conversion plate (3) is in the bottom surface of grating (2), is positioned at the middle front part of grating (2).The grating that described interval is chosen (2) is meant every a grating (2) and just chooses the fixedly grating (2) of frequency conversion plate (3) of need.Described frequency conversion plate (3) can be a rectangle metallic plate.
Claims (3)
1. a Cantilevered screen mainly includes crossbeam and grating, it is characterized in that: in each grating of screen cloth, on the grating of choosing, be fixed with the frequency conversion plate at interval, described frequency conversion plate is the bottom surface at grating, is positioned at the middle front part of grating.
2. Cantilevered screen according to claim 1 is characterized in that: the grating that described interval is chosen is meant every a grating and just chooses the fixedly grating of frequency conversion plate of need.
