The spiral sieve is characterized in that coupling bands are integrated into a whole, check rings are arranged in the middle of shaft holes of the coupling bands, and two ends of each check ring counteract against each driving shaft and the end face of each spiral shaft. As the coupling bands are integrated into a whole, the disassembly is convenient and fast, the time for maintaining a coal picker is effectively reduced, the labor intensity of workers is reduced, and the labor capacity is greatly improved. In addition, the utility model has simple structure, conveniently processing and low cost.
Description
Technical field
The utility model relates to a kind of equipment to do, wet coal or material sieving and grading, especially relates to a kind of spiral screen that utilizes helical axis to the material sieving and grading.
Background technology
Spiral screen is widely used in industries such as colliery, coal preparation plant, power plant, cement, coal is made sieving and grading for doing, wetting, spiral screen not only can embody efficient when the screening dry material, and can particularly there be stifled sieve aperture phenomenon during fine-grained wet stock at the screening wet stock, the screening percentage height is that present state internal classification is wet, sticking, the novel device of duff charcoal.The frame of spiral screen is along the stepped setting of the direction of motion of material, one group of compass screen surface is installed on each grade ladder, compass screen surface is made of one group of helical axis that is arranged in parallel, one end of helical axis is connected with power input shaft by coupling band, as Fig. 1, shown in 2, helical axis 1 and power input shaft 2 are connected with coupling band 3 by flat key 5 respectively, thereby helical axis 1 and power input shaft 2 are linked together by coupling band 3, by Fig. 1,2 can see, existing coupling band 3 is made of last coupling band 301 and 302 liang of lobes of following coupling band, and last coupling band 301 is fixedlyed connected by a plurality of screws 4 with following coupling band 302 and is integral.Because a spiral screen device has 48 even more helical axis 1, annual coal amount by spiral screen surpasses 1,000,000 tons, and the operating mode very severe of helical axis 1, makes helical axis 1 more fragile, needs often to change helical axis 1 in regular maintenance.Yet adopt the connection of said structure, changing helical axis 1 but becomes very big problem.Pull down helical axis 1, the screw 4 of will back-outing earlier, because the dead phenomenon of screw 4 rust often appears in passing through and abominable operating mode of a large amount of coal, changing helical axis 1 becomes a job of wasting time and energy, even delays the ordinary production running of enterprise.
The utility model content
The applicant is at above-mentioned problem, carried out research and improved, the rigidity hitch bar that provides a kind of coal picker of dismounting easily and fast to use.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of spiral screen, frame is along the stepped setting of the direction of motion of material, one group of compass screen surface is installed on each grade ladder, compass screen surface is made of one group of helical axis that is arranged in parallel, helical axis is connected with power input shaft by coupling band, power input shaft connects power source, power input shaft and helical axis are connected with coupling band by key respectively, power input shaft and helical axis are positioned on the same axis, described coupling band is an overall structure, the axis hole of coupling band middle part is provided with back-up ring, and the both ends of the surface of back-up ring offset with the end face of power input shaft and helical axis respectively.
Further:
Described back-up ring and coupling band are an overall structure.
The key that described power input shaft or helical axis are connected with coupling band is a flat key.
The key that described power input shaft or helical axis are connected with coupling band is a woodruff key.
The key that described power input shaft or helical axis are connected with coupling band is a spline.
Technique effect of the present utility model is:
Because the coupling band of the disclosed a kind of spiral screen of the utility model is an overall structure, power input shaft and helical axis directly insert coupling band and can use, easy accessibility and fast, reduce effectively spiral screen is safeguarded the spent time, reduced working strength of workers, raise labour productivity widely, in addition, the utility model is simple in structure, easy to process, with low cost.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Shown in Fig. 3,4,5,6,7, frame 7 of the present utility model is along the stepped setting of the direction of motion of material, one group of compass screen surface is installed on each grade ladder, compass screen surface is made of one group of helical axis that is arranged in parallel 1, every arrangement, helical axis 1 is connected with power input shaft 2 by coupling band 6 helical axis 1 by left-hand screw axle and right-hand screw between centers, power input shaft 2 connection power sources, in the present embodiment, power source is made of motor 8 and decelerator 9.Power input shaft 2 and helical axis 1 are connected with coupling band 6 by key 5 respectively, power input shaft 2 is positioned on the same axis with helical axis 1, coupling band 6 is an integrally-built axle sleeve, the axis hole of coupling band 6 middle part is provided with back-up ring 601, and the both ends of the surface of back-up ring 601 offset with the end face of power input shaft 2 and helical axis 1 respectively.In the present embodiment, back-up ring 601 is an overall structure with coupling band 6, and back-up ring 601 can prevent that coupling band 6 from making axial float on power input shaft 2 and helical axis 1; Back-up ring 601 also can use the hole back-up ring of standard, and processing one hole embeds the hole in the groove on the coupling band 6 with back-up ring with the groove of back-up ring in the axis hole of coupling band 6, can play the effect identical with present embodiment guide ring 601.In the utility model, the key 5 that power input shaft 2 and helical axis 1 are connected with coupling band 6 respectively can be common flat key, it also can be woodruff key, it also can be the key of spline or other types, the axle head of power input shaft 2 and helical axis 1 uses the key of any type, can determine according to actual needs.
Can see by Fig. 6, Fig. 7, power input shaft 2 and helical axis 1 can directly insert or transfer to coupling band 6, its installation and unloading process are very convenient, through the practical operation test, the a whole set of axle of changing on the spiral screen that 48 helical axis are arranged only needs about 2 hours, reduced spiral screen has been safeguarded the spent time, reduced working strength of workers, raised labour productivity widely.
