Description
Technical field:
The utility model relates to a kind of industrial screening plant, especially a kind of Cantilevered screen.
Background technology:
In the prior art, technique known is the Cantilevered screen in usefulness, and the grating of this screen cloth adopts straight excellent grating mostly, and row's grating is installed on every cross-arm, and the free end of each grating is all in the same side, and anticlogging strike is enclosed within the bottom of grating; This structure can effectively prevent the obstruction of material between grating in screening process, has improved screening efficiency; But, because the strike cover is the bottom at grating, the free end of grating is again all in the same side, hit cover and hit vibration that grating produced mainly at the free end of grating, therefore, the anticlogging effect of grating free end is obvious, and grating is near the just basic not vibration of the stiff end of cross-arm, do not have the effect of stopping up of preventing, this is the existing in prior technology weak point.
Summary of the invention:
The utility model is exactly at the existing in prior technology deficiency, and a kind of technical scheme of Cantilevered screen is provided, and the grating of this scheme adopts straight excellent grating and Z-shaped curved excellent grating, and the two ends of curved excellent grating are free end; Then be grating of fixed-site of the grating in interval on cross-arm, just have one to be the free end of grating between such two gratings that are fixed; Like this grating of arranging, between two cross-arms, the grating that hits the cover two ends all has free end, vibrates little problem so solved cross-arm stiff end grating, has also just improved to prevent the effect stopped up.
This programme is realized by following technical measures: include a plurality of cross-arms fixedly connected between side plate and the side plate, grating is housed on cross-arm, have by the strike cover that hits the cover stent support in the grating bottom surface, the characteristics of this programme are that described grating has straight excellent grating and Z-shaped curved excellent grating, and the two ends of curved excellent grating are free end; Straight excellent grating only is housed on the cross-arm of upper end, and the position of a grating at interval between the two straight excellent gratings, the straight excellent grating and the curved excellent grating of cross arrangement are housed on the cross-arm of lower end; All dress is bent excellent grating on each cross-arm between upper end cross-arm and the lower end cross-arm; Between two straight excellent gratings on the cross-arm of upper end, the curved excellent grating free end that is contained on adjacent next cross-arm with the upper end cross-arm is arranged; Two adjacent curved excellent gratings at same column are contained on two cross-arms up and down of the cross-arm in space.The concrete characteristics of this programme also have, and the following sieve rod of described Z-shaped curved excellent grating is fixed on the cross-arm, and the top sieve rod of curved excellent grating is passed by the cross-arm connecting plate on the cross-arm.When described cross-arm quantity was even number, the upper end cross-arm was straight excellent grating, and the lower end cross-arm of same column also is equipped with straight excellent grating.When described cross-arm quantity was odd number, the upper end cross-arm was straight excellent grating, and the lower end cross-arm of same column is equipped with curved excellent grating.Outer surface at described strike cover also is fixed with spring.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because grating has straight excellent grating and Z-shaped curved excellent grating in this scheme, the two ends of curved excellent grating are free end.Straight excellent grating only is housed on the cross-arm of upper end, and the position of a grating at interval between the two straight excellent gratings, the straight excellent grating and the curved excellent grating of cross arrangement are housed on the cross-arm of lower end.All dress is bent excellent grating on each cross-arm between upper end cross-arm and the lower end cross-arm.Between two straight excellent gratings on the cross-arm of upper end, the curved excellent grating free end that is contained on adjacent next cross-arm with the upper end cross-arm is arranged.Two adjacent curved excellent gratings at same column are contained on two cross-arms up and down of the cross-arm in space.The following sieve rod of described Z-shaped curved excellent grating is fixed on the cross-arm, and the top sieve rod of curved excellent grating is passed by the cross-arm connecting plate on the cross-arm.This structure, the arrangement that makes grating are that the grating that hits the cover two ends between two cross-arms all has free end, vibrate and are unfavorable for preventing blocking problem for a short time so solved cross-arm stiff end grating, therefore, have also just improved and prevent the effect stopped up.This shows that the utility model compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is that the A-A of Fig. 1 is to the sectional structure schematic diagram.
1 is side plate among the figure, and 2 for hitting cover, and 3 is spring, and 4 is curved excellent grating, and 5 is straight excellent grating, and 6 is the upper end cross-arm, and 7 is the cross-arm connecting plate, and 8 is cross-arm, and 9 is the lower end cross-arm, and 10 for sieve is excellent down, and 11 is the top sieve rod, and 12 for hitting the cover support.
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 has a plurality of cross-arms 8 fixedly connected between side plate 1 and the side plate 1, on cross-arm 8 grating is housed, have in the grating bottom surface by hitting the strike cover 2 that cover support 12 supports, also be fixed with spring 3 at the outer surface of described strike cover 2.The described grating of this programme has straight excellent grating 5 and Z-shaped curved excellent grating 4, and the two ends of curved excellent grating 4 are free end.Straight excellent grating 5 only is housed on upper end cross-arm 6, and the position of a grating at interval between the two straight excellent gratings 5, the straight excellent grating 5 and the curved excellent grating 4 of cross arrangement are housed on lower end cross-arm 9.All dress is bent excellent grating 4 on each cross-arm 8 between upper end cross-arm 6 and the lower end cross-arm 9, and the following sieve rod 10 of described Z-shaped curved excellent grating 4 is fixed on the cross-arm 8, and the top sieve rod 11 of curved excellent grating 4 is passed by the cross-arm connecting plate 7 on the cross-arm 8.Have between the two straight excellent gratings 5 on the upper end cross-arm 6 be contained in upper end cross-arm 6 adjacent next cross-arm 8 on curved excellent grating 4 free ends.Two adjacent curved excellent gratings 4 at same column are contained on two cross-arms 8 up and down of the cross-arm 8 in space.When described cross-arm 8 quantity were even number, upper end cross-arm 6 was straight excellent gratings 5, and the lower end cross-arm 9 of same column also is equipped with straight excellent grating 5; When described cross-arm 8 quantity were odd number, upper end cross-arm 6 was straight excellent gratings 5, and 9 of the lower end cross-arms of same column are equipped with curved excellent grating 4.This specific embodiment is to adopt five cross-arms 6, and the quantity of cross-arm 8 is odd number, so upper end cross-arm 6 is that 9 of the lower end cross-arms of same column are equipped with bent excellent grating 4 when straight excellent grating 5 was housed.
