Summary of the invention
The purpose of this utility model is exactly the shortcoming at prior art, and provide a kind of processing technology simple, the grating of the vibratory sieve of long service life, this kind grating adopts the method that grips fixedly the time, thereby overcome the disadvantage that to fix existing processing technology complexity in traditional extruding fixation with the rubber strip extruding, the technical scheme that adopts is: a kind of grating of vibratory sieve, comprise the grating body, it is characterized in that: described grating body is positioned at sleeve pipe, the diameter of described grating body is greater than the internal diameter of sleeve pipe, have at least one slit on the axial direction of described sleeve pipe, described grating body is fixed in the described sleeve pipe.
The technical solution of the utility model also has: described grating body is welded in the described sleeve pipe.
The technical solution of the utility model also has: the width in described slit is smaller or equal to 5mm.
The technical solution of the utility model also has: the number in described slit is one.
The technical solution of the utility model also has: be welded with anti-frotton on the described sleeve pipe.
The technical solution of the utility model also has: described anti-frotton is than the cover pipe range.
The technical solution of the utility model also has: described anti-frotton and grating body are isometric.
The beneficial effects of the utility model are: this vibratory sieve grating has comprised grating body and sleeve pipe, the diameter of grating body is greater than the internal diameter of sleeve pipe, fixedly the time, adopted the method for gripping between the two, thereby overcome in the extruding fixation with the fixing middle high shortcoming of processing technology complexity, cost that exists of rubber strip; The anti-frotton of welding on sleeve pipe, anti-frotton and grating body have formed the double stick structure, and screening efficiency is higher, therefore, the utlity model has simple, the with low cost advantage of processing technology, and in vibration processes, be difficult for producing phenomenons such as fatigue fracture, effectively prolonged the service life of grating.
Description of drawings
Accompanying drawing 1 is the structural representation of first kind of embodiment of this grating, accompanying drawing 2 is front views of second kind of embodiment of this grating, accompanying drawing 3 is left views of accompanying drawing 2, the structural representation of the vibratory sieve compass screen surface that accompanying drawing 4 is made up of this grating, wherein, the 1st, sleeve pipe, the 2nd, grating body, the 3rd, built-in beam, the 4th, gusset, the 5th, slit, the 6th, anti-frotton.
The specific embodiment
In conjunction with the accompanying drawings, the specific embodiment of the present utility model is described.This grating changes traditional extruding fixation and is the method for gripping fixedly the time, what is called grips method, and promptly the diameter of grating body 2 is greater than the internal diameter of sleeve pipe 1 and be fixedly connected between the two.
In embodiment 1, the diameter of sleeve pipe 1 is slightly less than the diameter of grating body 2, on its axial direction of sleeve pipe 1 upper edge, have at least 1 slit 5, the number in slit 5 is 1 in the present embodiment, the width in slit 5 is smaller or equal to 5mm, one end of grating body 2 is inserted in sleeve pipe 1, and sleeve pipe 1 slightly expands under the support of grating body 2, and grating body 2 is weldingly fixed on sleeve pipe 1.During installation, earlier with sleeve pipe 1 according to design one by one subtend be welded on the built-in beam 3 of compass screen surface both sides, then, pack into grating body 2 in the sleeve pipe 1 and make grating body 2 and sleeve pipe 1 fixing between the two, in order to play the effect of strengthening support, on sleeve pipe 1 and built-in beam 3, be welded with gusset 4, in soldering sleeve 1 and welding gusset 4 processes, formed weld seam, after the processing, just formed the screen cloth of vibratory sieve like this.
In the present embodiment, the preparation method that the processing grating adopts may further comprise the steps:
1), processes grating body 2 according to the art work sheet blanking;
2) according to the art work sheet blanking, process sleeve pipe 1, the internal diameter of sleeve pipe 1 is less than the diameter of grating body 2, and processes at least one slit 5 at its axial direction of sleeve pipe 1 upper edge, and the width in slit 5 is smaller or equal to 5mm;
3) grating body 2 is inserted in the sleeve pipe 1, and 5 places weld together in the slit with sleeve pipe 1.
In embodiment 2; the internal diameter of sleeve pipe 1 is slightly less than the diameter of grating body 2; on its axial direction of sleeve pipe 1 upper edge, have a slit 5; the width in slit 5 is smaller or equal to 5mm; sleeve pipe 1 slightly expands under the support of grating body 2; weld at 5 places in the slit; just sleeve pipe 1 and grating body 2 can be fixed together; frotton 6 is prevented in welding on sleeve pipe 1 then; the length of the comparable sleeve pipe 1 of length of anti-frotton 6 is long; generally can grow 10-5mm; also can be isometric with grating body 2, the purpose of the anti-frotton 6 of welding is that protective casing 1 is not is not worn and torn too early, to prolong the life-span of sleeve pipe 1; when grating body 2 and anti-frotton 6 are long together, form the double stick structure, improved screening efficiency.When grating is installed, earlier grating body 2 is packed in the sleeve pipe 1 and make grating body 2 and sleeve pipe 1 fixing between the two, then, with sleeve pipe 1 and grating body 2 according to design one by one subtend be welded on the built-in beam 3 of compass screen surface both sides, in order to play the effect of strengthening support, on sleeve pipe 1 and built-in beam 3, be welded with gusset 4, after the processing, just formed the screen cloth of vibratory sieve like this.
