Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
Embodiment 1:
As shown in Figure 1 and Figure 2, the present embodiment comprises water source 1, water source 1 connects head pivot 2 by pipeline, the water side of head pivot 2 connects the one end that is embedded in the following main 3 in earth's surface, on main 3, be arranged at intervals with some by three-way connection 4, connect go out ground standpipe 5, each goes out ground standpipe 5 and connects at least one valve 6, and the water side of each valve 6 connects one by an outlet pipe 7 and has externally threaded fast connector 8.The female Quick connection sleeve 9 of one inner port tool, the other end is provided with a circle flange, it on the internal diameter adjacent with flange, is one section of Taper Pipe reducing from inside to outside, in the Taper Pipe of Quick connection sleeve 9, be relatively set with a tapered sleeve 10 with hangnail mouth, the arrival end of one arm 11 is passed to Quick connection sleeve 9 and tapered sleeve 10 simultaneously, its port leans the inner port place at fast connector 8, then by rotation Quick connection sleeve 9, coordinate with the external screw thread of any one fast connector 8 and screw extruding arm 11, arm 11 and tapered sleeve 10 the effect lower catch hoop of hangnail mouth be integral (as shown in Figure 3).End at arm 11 arranges the female Quick connection sleeve 9 of a tool too, in the Taper Pipe of Quick connection sleeve 9, be provided with too a tapered sleeve 10 with hangnail mouth, one has externally threaded shutoff 12 front ends is provided with an inward recess 13, and end is provided with one for connecting the hanging sleeve 14 that drags engine.When arm 11 ends lean the bottom at shutoff 12 inward recess through Quick connection sleeve 9 and tapered sleeve 10 ends simultaneously, by rotation Quick connection sleeve 9, coordinate with the external screw thread of shutoff 12 and screw extruding arm 11, and then arm 11 ends are integral to (as shown in Figure 4) at the hangnail mouth effect lower catch hoop of tapered sleeve 10.
As shown in Figure 1, shown in Figure 5, be arranged at intervals with some apopores 15 on arm 11, corresponding each apopore 15 is provided with a nozzle protecting device 16 on arm 11.On the top cover 17 of nozzle protecting device 16 and base 18, be bolted the saddle 19 of a upper and lower fastening; the middle part of saddle 19 inwalls is provided with a groove; in groove, be provided with a sealing ring 20; so that the 15 periphery sealings of the apopore of arm 11 are arranged in saddle 19, at the top of saddle 19, be threaded connection a shower nozzle 21.
In above-described embodiment, the shape of nozzle protecting device 16 top covers 17 and base 18 can change to some extent with being connected all, and such as base 18 is plate-like, top cover 17 is bowl-shape (as shown in Figure 5); Again such as base 18 is peviform, the curved plate-like of top cover 17 (as shown in Figure 6).
As shown in Figure 1, Figure 7 shows, when the present embodiment is used, hanging sleeve 14 on arm 11 tail end plugs 12 is connected to and is dragged on engine 22, startup drags engine 22 and drives arms 11 to enter first row plot, then the water inlet of arm 11 is connected in the water side snap joint 8 of first row plot valve 6 by Quick connection sleeve 9, opens valve 6 and start first row plot to spray.After completing the sprinkling irrigation of first row plot, close first row plot valve 6, and unclamp the screw thread between Quick connection sleeve 9 and fast connector 8, make the related arm 11 of Quick connection sleeve 9 separated with first row plot valve 6.Restart and drag engine 22 and drag second row plot with arm 11, again arm 11 is connected on the fast connector 8 of second row plot valve 6 by Quick connection sleeve 9, open valve 6 and start second row plot to spray, by that analogy, complete whole sprinkling irrigation tasks.
Embodiment 2:
As shown in Fig. 6, Fig. 8, the present embodiment difference from Example 1 is: the water side of head pivot 2 directly connects flexible main 23 one end that are arranged on more than earth's surface, the other end of main 23 is provided with a valve 24, the water side of valve 24 is by connecting a fast connector 8 identical with embodiment 1 structure, on fast connector 8, by a Quick connection sleeve 9 identical with embodiment 1 structure, connect an arm 11 identical with material with embodiment 1 structure.
During the present embodiment work, will drag engine 22 and drag plot to be sprayed with arm 11, the water inlet of arm 11 will be connected on the fast connector 8 of main 23 by Quick connection sleeve 9, and then open valve 24 and start to spray.After now dragging engine 22 and both can having waited for that first parking spot had been sprayed, drive arm 11 to transfer to again next sprinkling irrigation position and spray, also can drag arm 11 slow mobile sprinkling irrigation continuously centered by head pivot 2.
Embodiment 3:
As shown in Fig. 2, Fig. 6, Fig. 9, the present embodiment difference from Example 1 is: the water side of water source and head pivot 1 is connected with three (only as example by main pipe 2 parallel pipeline (not shown) intervals, but be not limited to this) be embedded in the main 3 below earth's surface, on each main 3, be arranged at intervals with some by three-way connection 4, connect go out ground standpipe 5, each top that goes out ground standpipe 5 is connected with a valve 6, and the water side of each valve 6 connects a fast connector 8.At any fast connector 8, can, by a Quick connection sleeve 9 with embodiment 1 same structure, connect an arm 11 identical with connected mode with embodiment 1 structure.
The present embodiment when work: drag engine 22 in tow the end of arm 11 along the direction of arrow identifying in figure, move ahead, when travelling, to the water inlet of the first plot arm 11, stop during near the first plot valve 6, on the fast connector 8 that valve 6 water sides in the Quick connection sleeve of the water inlet of arm 11 9 connection the first plot are connected, opening valve 6 starts the first plot to spray, after having sprayed in the first plot, close the valve 6 in the first plot and unclamp Quick connection sleeve 9 and fast connector 8 between screw thread, make the related arm 11 of Quick connection sleeve 9 separated with the first plot valve 6, drag engine 22 in tow arm 11 along direction running to the second plot of arrow logo in figure, when travelling, to the water inlet of the second plot arm 11, stop during near the second plot valve 6, again arm 11 is connected on the fast connector 8 of the second plot valve 6 by Quick connection sleeve 9, opening valve 6 starts the second plot to spray, and the direction marking by arrow by that analogy sequentially completes the sprinkling irrigation task in 1～16 plot successively.Owing to dragging engine 22, be directly connected with arm 11 ends, therefore dragging engine 22 must turn around according to the direction of arrow, and fast connector 8 places by arm 11 water inlets near the water side of each plot valve 6 realize fast and connecting.
In above-described embodiment 1 and embodiment 3, rigidity main 3 below earth's surface is embedded in more than also can be arranged on earth's surface, like this, on main 3, pass through spaced some three-way connections 4, just can connect respectively a valve 6, the water side of each valve 6 connects a fast connector 8 by an outlet pipe 7.
In above-described embodiment, the external diameter of arm 11 is slightly larger than the internal diameter of tapered sleeve 10.
In above-described embodiment, arm 11 can adopt anti-aging black flexible polyethylene (PE) pipe of existing irrigation system.The diameter of its every arm 11 is definite according to the flow of shower nozzle 21, shower nozzle 21 spacing distances, arm 11 length etc., and generally adopting diameter specifications is D40, D50, D63 and D75 pipe.Also can determine according to traditional sprinkling irrigation system method for designing the diameter of concrete arm 11.When main 3 be arranged in parallel, arm 11 length are 1/2nd of two spacing.The spacing of shower nozzle 21 can be arranged at a certain distance according to field situation.
In above-described embodiment, in above-described embodiment, saddle 19 is existing common saddle on market, and shower nozzle 21 is also the common Rocker arm spray head on market.
The various embodiments described above are only for illustrating the present invention, and wherein the structure of each parts, connected mode etc. all can change to some extent, and every equivalents of carrying out on the basis of technical solution of the present invention and improvement, all should not get rid of outside protection scope of the present invention.
