A kind of fixture of vibrating screen mesh
Technical field
The present invention relates to the fixture of the raw-material screening plants, particularly a kind of vibrating screen mesh such as a kind of sorting bulk or granular ore.
Background technology
The screen cloth fixed form of present known vibratory sieve is that screen cloth is placed on the screen frame, pushes down screen cloth with round steel, then blocks round steel with U bolt, and with pressing plate it is pressed on the screen frame.When vibratory sieve is worked because round steel and screen cloth are that line contacts, between round steel and the U bolt for some contact, and U bolt is in round steel location not, so to swing and sliding along round steel can appear in U bolt, thus appearance become flexible, screen cloth can not be compressed.Shaking up and down can appear in screen cloth like this, is easy to breakage.
Summary of the invention
The fixture that the purpose of this invention is to provide a kind of vibrating screen mesh so that screen cloth is fixing reliable, thereby prolongs the service life of screen cloth.
The technical solution used in the present invention is: a kind of fixture of vibrating screen mesh, comprise screen frame and screen cloth, and be welded with clamping plate in the upper of screen frame along both sides, the downside of rubber strip is sandwiched in the upper groove along forming of two clamping plate and screen frame; Screen cloth is placed in the end face of rubber strip, and the square steel that is positioned at directly over the rubber strip is pushed down screen cloth.Center, the top of square steel is processed with the arc groove that cooperates with semicircle in the U bolt elbow, and it is interior and pass screen cloth that U bolt snaps in arc groove on the square steel; Pressing plate is provided with and U bolt two through holes movingly, two through hole covers of pressing plate U bolt of packing into; Between two through holes two blocks guiding steel plates are vertically welded in above the pressing plate, two blocks of guiding steel plates inboard with the screen frame outside slip movingly, two blocks of guiding steel plates are inserted in screen frame; Be welded on the screen frame and form stopper slot near the spacing steel plate at guiding steel plate two ends, the guiding steel plate two ends and the spacing steel plate that are positioned at stopper slot are slidingly matched; Cover is packed into, and to be inserted in double nut fastening for U bolt bottom behind the pressing plate.
The invention has the beneficial effects as follows: screen cloth is placed in and is positioned on the screen frame along on the resilient rubber strip, push down screen cloth with the square steel that is processed with arc groove, when snapping in the square steel arc groove that is mated with U bolt, U bolt is that line contacts and fastening being positioned in the square steel arc groove can not be slided with square steel.The pressing plate cover is packed into behind the U bolt bottom, and the guiding steel plate inserts by clamping in the formed stopper slot of spacing steel plate that is welded on the screen frame and with screen frame.Behind the fastening U bolt of double nut bottom, tightly pushing down the square steel of screen cloth, the U bolt that snaps in the square steel arc groove, the pressing plate that inserts and clamp screen frame all is firmly fixed, screen cloth can stand judder and not produce loosening, guarantee that screen cloth is fixing reliable, can not occur loosening and produce up and down shaking, cause sieve breakage, thereby greatly prolong the service life of screen cloth.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structure cutaway view of the present invention.
Fig. 2 is the left view of Fig. 1.
Among the figure: 1, screen cloth, 2, U bolt, 3, be processed with the square steel of arc groove, 4, rubber strip, 5, screen frame, 6, spacing steel plate, 7, the guiding steel plate, 8, pressing plate, 9, nut, 10, clamping plate.
The specific embodiment
A kind of fixture of vibrating screen mesh comprises screen frame and screen cloth, and at the upper clamping plate 10 that are welded with along both sides of screen frame 5, the downside of rubber strip 4 is sandwiched in the upper groove along forming of two clamping plate 10 and screen frame 5; Screen cloth 1 is placed in the end face of rubber strip 4, and the square steel 3 that is positioned at directly over the rubber strip 4 is pushed down screen cloth 1; Center, the top of square steel 3 is processed with the arc groove that cooperates with semicircle in U bolt 2 elbows, and it is interior and pass screen cloth 1 that U bolt 2 snaps in arc groove on the square steel 3; Pressing plate 8 is provided with and U bolt 2 two through holes movingly, two through hole covers of pressing plate 8 U bolt 2 of packing into, two blocks of guiding steel plates 7 between two through holes are vertically welded in above the pressing plate 8, two blocks of guiding steel plates 7 inboard with screen frame 5 outside slips movingly, two blocks of guiding steel plates 7 are inserted in screen frame 5; Be welded on the screen frame 5 and form stopper slot near the spacing steel plate 6 at guiding steel plate 7 two ends, guiding steel plate 7 two ends and the spacing steel plate 6 that are positioned at stopper slot are slidingly matched; Cover is packed into, and to be inserted in double nut 9 fastening for U bolt 2 bottoms behind the pressing plate 8.
Screen cloth is placed in and is positioned on the screen frame 5 along on the resilient rubber strip 4, push down screen cloth 1 with the square steel 3 that is processed with arc groove, when snapping in the square steel arc groove that is mated with U bolt 2, U bolt 2 contacts for line with square steel 3 and fastening being positioned in the square steel arc groove can not be slided.After pressing plate 8 overlapped U bolt 2 bottoms of packing into, guiding steel plate 7 inserted by clamping in the spacing steel plate 6 formed stopper slots that are welded on the screen frame 5 and with screen frame 5.Behind double nut 9 fastening U bolts 2 bottoms, tightly pushing down the square steel 3 of screen cloth 1, the U bolt 2 that snaps in the square steel arc groove, the pressing plate 8 that inserts and clamp screen frame 5 all is firmly fixed, screen cloth can stand judder and not produce loosening, guarantee that screen cloth 1 is fixing reliable, can not occur loosening and produce up and down shaking, cause sieve breakage, thereby greatly prolong the service life of screen cloth 1.
