Abstract
The utility model provides a cantilever screen surface. The utility model comprises a plurality of cantilever screens forming a screen surface by connection of heads and tails from high position to low position. Each cantilever screen is composed of a transverse beam and screen strips. The utility model is characterized in that the transverse beam of each cantilever screen is fixedly provided with a vertical plate or an angle plate or a flat plate which is parallel to the transverse beam, and the upper top surfaces of the vertical plates or the angle plates or the flat plates correspond to the top ends of the screen strips on the upper layer and form clearances. Owing to the existence of the vertical plates or the angle plates or the flat plates in the structure, the height distance between the screen strips on the upper layer and the lower layer can be increased. When the screened articles of an upper layer screen fall onto the top surface of the transverse beams, the screened articles can be flushed off by the screened articles of the upper layer screen. Thus, the materials can not be accumulated on the top surface of the transverse beams any more. Therefore, the vibration of the screen strips on the upper layer can not be influenced. As a consequence, the utility model ensures the screening efficiency of the upper layer screen and simultaneously ensures the normal running of the screen surface.
Description
Affiliated technical field:
The utility model relates to a kind of vibratory sieve that is used for industrial screening material, especially a kind of Suspension arm sieve compass screen surface.
Background technology:
In the prior art, known Suspension arm sieve all is made up of crossbeam and grating, and the last end face of crossbeam all is the plane, after Suspension arm sieve is formed compass screen surface, in use, the crossbeam position of lower floor's Suspension arm sieve all be in upper strata Suspension arm sieve grating below, so the screenings of upper sieve will drop on the crossbeam of lower screen, if the material that is sized is the bigger material of stickiness, the material that drops on the crossbeam is piled up on crossbeam, the material of piling up on crossbeam reaches certain height, will hinder the vibration of upper strata grating, makes upper sieve reduce screening efficiency, when this is a prior art to the bigger material of screening stickiness, existing disadvantage.
Summary of the invention:
The utility model is at the existing in prior technology deficiency, and the Suspension arm sieve compass screen surface technical scheme that provides a kind of suitable screening to have the stickiness material.This scheme has adopted and be fixed with riser or gusset or a flat board parallel with crossbeam on crossbeam, this just can increase the distance of height between the upper and lower layer grating, thing is fallen the crossbeam end face behind the sieve of upper sieve, will be washed away by the follow-up sieve back thing of upper sieve, make the crossbeam end face or else have the material of accumulation, just can not hinder the vibration of upper strata grating yet, guarantee to make the screening efficiency of upper sieve, guarantee the normal operation of compass screen surface simultaneously.
This programme is realized by following technical measures: include a plurality of Suspension arm sieves from high to low, initial and end is formed compass screen surface relatively, described Suspension arm sieve then is made up of crossbeam and grating, the characteristics of this programme are to be fixed with riser or gusset or a flat board parallel with crossbeam on the crossbeam of described each Suspension arm sieve, and the last end face of this riser or gusset or flat board is corresponding with the top of upper strata grating and gapped.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing to be fixed with riser or gusset or a flat board parallel with crossbeam in this scheme on the crossbeam of described each Suspension arm sieve, the last end face of this riser or gusset or flat board is corresponding with the top of upper strata grating and gapped.This structure, because riser or gusset or dull and stereotyped existence are arranged, just can increase the distance of height between the upper and lower layer grating, thing is fallen the crossbeam end face behind the sieve of upper sieve, will be washed away by thing behind the sieve of upper sieve, makes the crossbeam end face or else have the material of accumulation, therefore, just can not hinder the vibration of upper strata grating yet, guarantee to make the screening efficiency of upper sieve, guarantee the normal operation of compass screen surface simultaneously.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 uses the structural representation of the specific embodiment of riser for the utility model.
Fig. 2 uses the structural representation of the specific embodiment of gusset for the utility model.
Fig. 3 uses the structural representation of the dull and stereotyped specific embodiment for the utility model.
1 is Suspension arm sieve among the figure, and 2 is riser, and 3 is crossbeam, and 4 is grating, and 5 is gusset, and 6 is dull and stereotyped.
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 three specific embodiment.
By accompanying drawing 1 as can be seen, the Suspension arm sieve compass screen surface of this programme, a plurality of Suspension arm sieves (1) are arranged from high to low, initial and end is formed compass screen surface relatively, described Suspension arm sieve (1) then is made up of crossbeam (3) and grating (4), this programme is to be fixed with a riser (2) parallel with crossbeam (3) on the crossbeam (3) of described each Suspension arm sieve (1), and the last end face of this riser (2) is corresponding with the top of upper strata grating (4) and gapped.Described gap can be greater than half of grating amplitude.
By accompanying drawing 2 as can be seen, the Suspension arm sieve compass screen surface of this programme, a plurality of Suspension arm sieves (1) are arranged from high to low, initial and end is formed compass screen surface relatively, described Suspension arm sieve (1) then is made up of crossbeam (3) and grating (4), this programme is to be fixed with a gusset (5) parallel with crossbeam (3) on the crossbeam (3) of described each Suspension arm sieve (1), and the last end face of this gusset (5) is corresponding with the top of upper strata grating (4) and gapped.Described gap can be more than or equal to half of grating amplitude.
By accompanying drawing 3 as can be seen, the Suspension arm sieve compass screen surface of this programme, a plurality of Suspension arm sieves (1) are arranged from high to low, initial and end is formed compass screen surface relatively, described Suspension arm sieve (1) then is made up of crossbeam (3) and grating (4), this programme is to be fixed with a flat board (6) parallel with crossbeam (3) on the crossbeam (3) of described each Suspension arm sieve (1), and the last end face of this flat board (6) is corresponding with the top of upper strata grating (4) and gapped.Described gap can be greater than half of grating amplitude.
