Abstract
The utility model relates to a rotating injection head and comprises an injection head seat (1), injection nozzles (2), a rotating device (3), a water wheel (4) and a liquid entering pipe (5). The upper end of the liquid entering pipe (5) is fixedly connected with an outer liquid perfusion pipe and the middle section of the liquid entering pipe (5) is inserted into the rotating device and is rotationally connected with the rotating device. The lower end of the liquid entering pipe through a seal ring is plugged in the inner chamber of the injection head seat (1) and the upper part of the injection head seat (1) is fixedly connected with the rotating device. The side wall of the lower part of the injection head seat (1) is provided with at least two injection nozzles (2) and the water wheel (4) is fixedly connected with the drive shaft of the rotating device (3) and is positioned on one side of the rotating device (3). At least one injection nozzle (2) is positioned on the inner side of the water wheel (4) in the inclined direction and the liquid stream injected by the injection nozzle (2) can drive the water wheel (4) to generate the high speed rotation. Therefore, the rotating device (3) and the injection head seat (1) fixed with the rotating device (3) are driven to rotate.
Description
The utility model relates to a kind of rotary sprayer unit, particularly a kind of rotating sprinkler.
In the prior art, rotating sprinkler is mainly by nozzle boss, adjustable nozzle, differential gear, the recoil shower nozzle constitutes, fixedly connected with outer woven hose screw thread in the nozzle boss upper end, on the upper portion side wall of the fixedly connected nozzle boss of adjustable nozzle screw thread, and communicate with its inner chamber, differential gear has two groups, one group of differential gear is fixed on the lower sides of nozzle boss, another group differential gear is meshed with it, fixedly connected with the recoil shower nozzle in the central shaft lower end of two groups of differential gears, the lower end of nozzle boss is slidingly connected by sealing ring and recoil shower nozzle, and the recoil shower nozzle is communicated with the inner chamber of nozzle boss.
When existing rotating sprinkler is worked, woven hose is imported in nozzle boss has certain pressurised fluid stream, the liquid flow point is not by adjustable nozzle and the ejection of recoil shower nozzle, the recoil strength that produces during recoil shower nozzle ejection liquid stream, make when itself producing rotation at a high speed, drive nozzle boss by coupled differential gear and do to horizontally rotate.
Existing rotating sprinkler, the recoil shower nozzle of its underpart is when rotating at a high speed, and recoil strength can not be balanced, thereby causes the unstable working condition of whole shower nozzle; The rotation of the high speed of recoil strength shower nozzle also makes the ring wear of itself and nozzle boss connecting place heavier, easily causes seal failure; Differential gear is in open state, easily spatters the liquid that is stained with ejection, is corroded and causes insufficient lubrication between gear, influences the operate as normal of differential gear, and has shortened its service life; The volume of in addition existing rotating sprinkler is bigger, and structure is not really compact.
The purpose of this utility model is to provide a kind of volume less, compact conformation, reliability height, the rotating sprinkler of long service life at the deficiency of existing rotating sprinkler existence.
The utility model is to be achieved through the following technical solutions: as Fig. 1, shown in Figure 2, a kind of rotating sprinkler, include nozzle boss (1), nozzle (2) constitutes, it is characterized in that: also include whirligig (3), water wheels (4), feed tube (5), fixedly connected with outer woven hose in the upper end of feed tube (5), the stage casing is inserted in the whirligig and with whirligig and is rotationally connected, the lower end is plugged in nozzle boss (1) inner chamber by sealing ring, also whirligig is fixedly connected on the top of nozzle boss (1), be connected with at least two nozzles (2) on the sidewall of the bottom of nozzle boss (1), the inner chamber of nozzle boss (1) is communicated with feed tube (5) and nozzle (2) respectively, and water wheels (4) are fixedlyed connected with the power transmission shaft of whirligig (3), be positioned at the one side, the oblique inboard that is positioned at water wheels (4) of at least one nozzle (2), the liquid stream of its ejection can promote water wheels (4) and produce rotation at a high speed, thereby driven rotary device (3) reaches and the rotation of the nozzle boss (1) that it is fixing.
Whirligig (3) can be by box body (6), lid (7), be installed in the worm screw (8) in the box, (9), worm gear (10), (11), bevel gear (12) constitutes, box body (6) is fixedlyed connected with the top of nozzle boss (1), water wheels (4) link to each other with the end of worm screw (8), worm screw (8) is by being fixed on the two rolling bearings supporting in the box body (6), worm screw (8) links to each other with worm gear (10), be shaped on a bevel gear on the central shaft of worm gear (10), it drives bevel gear (12), bevel gear (12), drive worm screw (9) and worm gear (11) engagement, worm gear (11) then is fixed on the middle part periphery wall of the feed tube (5) that extends through box body (6).
Nozzle (2) can be short distance or middle distance or remote nozzle.
During rotary nozzle work, woven hose is imported the liquid stream of certain pressure in nozzle boss (1) by feed tube (5), spray by nozzle (2), promote water wheels (4) and produce rotation at a high speed, water wheels (4) are then by coupled worm screw (8), pass through worm gear (10) bevel gear (12) successively, the break-in of worm screw (9) is slowed down, promoting worm gear (11) rotates, can't rotate because the feed tube (5) that links to each other with worm gear (11) is fixing, rotate thereby oppositely promote whole whirligig, rotate, realize the purpose of rotating spraying thereby drive the nozzle boss (1) of fixedlying connected with it.
The utility model adopts the outer whirligig that box body is arranged, and it places all movement parts except that water wheels in the box body, and compact conformation is convenient to lubricate, and volume is little, avoids internal motion spare to be stained with mutually with the liquid mist, has improved functional reliability, has prolonged service life; Sealing ring places rotation sealing place slowly, has guaranteed good seal, has prolonged the service life of sealing ring.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is that the A of Fig. 1 is to view
Fig. 1 and Fig. 2 have provided most preferred embodiment of the present utility model.
