As shown in Figure 1, a kind of screw with long screw pitch chute, comprise center stand column, spiral chute, inlet point 1, discharging opening 4, described center stand column comprises vertical columns 201 and N telescopic column 202, N is more than or equal to 1, described vertical columns 201 is connected with N telescopic column 202 inner and outer movable successively, be preferably and be threaded, when N is greater than 1, described vertical columns is connected with a telescopic column internal and external threads, No. one telescopic column is connected with No. two telescopic column internal and external threads, No. two telescopic column is connected with No. three telescopic column internal and external threads, by that analogy, the worm drive that form the screw rod rotation and move along axis.The helical pitch of described vertical columns and all telescopic columns is identical.
Described spiral chute is divided into fixed chute 301 and N retractable chute 302, described fixed chute 301 and N retractable chute 302 overlap successively, when N is greater than 1, fixed chute is enclosed within the outside of a retractable chute, a retractable chute is enclosed within the outside of No. two retractable chutes, No. two retractable chutes are enclosed within the outside of No. three retractable chutes, by that analogy, all form the transmission of along hand of spiral, rotating and moving along axis direction, described fixed chute 301 and N retractable chute 302 are the constant pitch helical structure, and all identical with the helical pitch of described vertical columns 201 screw motions, described fixed chute 301 is fixedly connected with N telescopic column 202 with described vertical columns 201 successively one to one with N retractable chute 302.Described fixed chute 301 is identical with N retractable chute 302 helical pitches, and described N value is preferably 1, and fixed chute is connected with vertical columns, and retractable chute is connected with telescopic column.
Described spiral chute is made by stainless steel sheet, and when part is worn and torn, but monolithic is changed.For making chute increase durability and reduce friction coefficient, the inside face of spiral chute is provided with the corrosion-resistant steel round bar 5 evenly distributed along hand of spiral, with the contact surface that reduces bag and chute and fall bottom-friction factor.Described center stand column is that solid drawn pipe is made.Described spiral chute is high-grade limit circular arc type.
Also comprise and drive the flexible hydraulic efficiency gear 6 of center stand column, described hydraulic efficiency gear 6 is fixedly installed on described center stand column top, the piston rod of hydraulic efficiency gear 6 is fixedly connected with the telescopic column 202 that is positioned at the top, when hydraulic efficiency gear 6 is flexible, telescopic column 202 is done flexible and spinning movement simultaneously, retractable chute 302 is also done flexible and spinning movement simultaneously, thereby realize that spiral chute is motor-driven flexible at any time, so just can realize that seamless long distance is flexible, not need screw pair, nut etc. to control spinning movement.
During work, according to the shipment type adjust the flexible stroke of spiral chute, meet the shipment needs.
As shown in Figure 2 and Figure 3, preferably, also comprise lower rotary disk, described lower rotary disk comprises disk body 10, pivoting support 6, rotating blade drive 7, frame 8 next time, the outer ring of described pivoting support 6 is fixedly connected with described disk body 10, and the inner ring of described pivoting support 6 is fixedly connected with described frame 8, and described frame 8 tops are fixedly connected with described center stand column bottom by butt flange 9, described rotating blade drive next time 7 is arranged on described frame 8, and is connected with described pivoting support 6.Be provided with striker plate 11, guide chute 12, gear bag device 13 on described disk body 10, described striker plate 11 is extended to the outer segment distance of external diameter of described disk body 10 by described disk body 10 center, described gear bag device 13 is arranged on described striker plate 11, described guide chute 12 abuts against described striker plate 11 1 sides, one end of described guide chute 12 is concordant with the upper surface of described disk body 10, and the other end reaches described lower rotary disk below.Also be provided with protective frame 14 on described disk body 10, described protective frame 14 was around the cylindrical of described disk body 10 one week, and at described guide chute 12 place's openings, described opening matches with described guide chute 12, described disk body 10 has certain inclination angle, to guarantee bag, is easy to slide into the outer rim place of disk body 10 and rotates in company with disk body 10 at the outer rim place of disk body 10.
When bag cargo when the lower discharge port 4 of spiral chute is fallen disk body 10, disk body 10 rotates along center of gyration, bag is encountered on striker plate 11 after certain angle along circular-rotation in company with disk body 10 rotation bags at the outer rim place of disk body 10 under the drive of disk body 10, under the centrifugal action of disk body 10, continue to slide along striker plate 11, after encountering the gear bag device 13 be arranged on striker plate 11, one side of bag stops and another side rotates motion because disk body 10 does not stop operating, then glide and arrive freighter through guide chute 12, so just make bag rotate an angle, make it to be rotated into as required horizontally-arranged or longitudinal arrangement, be convenient to the code bag, lower rotary disk can also be avoided because of the indefinite drawback in motor-driven flexible rear discharging opening 4 positions of spiral chute.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
