Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection domain of the present utility model.
In FIG, a kind of vertical rocker-arm formula irrigation sprinkler shower nozzle, comprise sprinkler body, rocking arm 1 and commutator, sprinkler body is primarily of the nozzle be connected to each other, jet pipe 4, swan neck 12 is formed, deflector 17 is fixed with on the upside of the front end of rocking arm 1, described rocking arm 1 is elongated, rocking arm 1 offers strip hole in middle part, rocking arm 1 has two relative side plates above middle part, by bearing, a rotating shaft is installed between biside plate, the direction vertical with this rotating shaft is same arranges a reversing shaft, the bearing of reversing shaft and the bearing of rotating shaft are fixed in reversing shaft bearing 15, reversing shaft bearing 15 is positioned at strip hole, and pass downwardly through bearing block 3 and to be fixed between jet pipe 4 and nozzle top, biside plate arranges the limited block 2 stretching to inner side, position and the reversing shaft bearing 15 of limited block 2 are suitable, the hollow pipe that sprinkler body connects in swan neck 12 lower end is fixed on step 8 by bearing, commutator comprises commutation parts and commutation spring 9, the upper end of commutation parts is fixedly attached to the below of reversing shaft bearing 15 by pull bar 14, commutation spring 9 is fixed on the outside of step 8.Because rocking arm 1 is positioned at the top of sprinkler body, when rocking arm 1 vertically waves around rotating shaft; the rearward end of rocking arm 1 can be sprayed onto sprinkler body; thus play spacing effect; and the reversing shaft bearing 15 on rocking arm 1 can limit the amplitude of vertically waving by the limited block 2 on side plate; by above two place's position-limit mechanisms, the vertical oscillation of rocking arm 1 realizes in certain angle interval.
As a kind of specific implementation structure of the present embodiment, described commutation parts comprise contiguous block 10, middle contiguous block 7 and lower connecting block 6, the lower end of upper contiguous block 10 and the upper end thereof of middle contiguous block 7, the middle lower end of contiguous block 7 and the upper end thereof of lower connecting block 6, be connected on the pin joint of lower connecting block 6 by spring outside the upper end of upper contiguous block 10, the communtation arm 5 that lower connecting block 6 stretches out downwards is between commutation spring 9, obtain according to commutation spring 9 spacing the sprinkling wide cut expected, middle contiguous block 7 is spacing by the block 11 on bend pipe.Add that the upper end of commutation parts is fixedly attached to the below of reversing shaft bearing 15 by pull bar 14, commutation spring 9 is fixed on the outside of step 8.Rotation With Changing sets the mobile space of communtation arm 5 to spring 9, and communtation arm 5 acts on reversing shaft bearing 15 after each contiguous block and spring, pull bar 14 interoperation, realizes the rotation commutation control to rocking arm 1.
As further improvement of this embodiment scheme be, described deflector 17 has two symmetrical diversion cavity, and the bottom surface of diversion cavity is bent upwards, diversion cavity is positioned at middle dividing plate in front end in block face bending in opposite directions, and the rear upper side of dividing plate fixes one piece of horizontal baffle.Compare the deflector structure of traditional del, deflector 17 of the present utility model has two diversion cavity, and each diversion cavity is equipped with the face of two place's water conservancy diversion, when namely spraying to side diversion cavity from the water of nozzle injection, the curved surface of front end to deflector 17 with downward active force, the block face of side with reciprocal thrust, thus causes the vertical oscillation of rocking arm 1 and left and right Double-directional rotary to rocking arm 1, impels the realization of better sprinkling irrigation effect.
A kind of preferred design of the present embodiment is, as shown in Figure 2, described jet pipe 4 is barretter, and the inner uniform some one end of barretter are fixed on inwall, the current stabilization sheet 18 at other end point tube center, current stabilization sheet 18 has the consistent camber in direction, leaves cylindrical cavity 19 in the middle of barretter.Barretter can carry out current stabilization to water, sprays farther range to reach from nozzle.
Preferably, described nozzle is fixed on the front end of jet pipe 4 by nozzle nut 16.Such structure, is beneficial to guarantee and fast and effeciently changes shower nozzle.
Further, balancing weight 13 is fixed with in the rearward end of described rocking arm 1.Balancing weight 13 coordinates swing arm to realize rotary motion better.
Again less preferably, adopt stainless steel at described rocking arm 1, barretter and sprinkler body adopt Aluminum alloy tensile shaping.Improve resistance to corrosion, ageing-resistant, not yielding, improve product quality, more durable in use.
Can also install torsion spring in rotating shaft one end of rocking arm 1, the position of adjustment torsion spring external part realizes the adjustment of rocking arm 1 rotary speed.
The above; be only preferred embodiment of the present utility model, not any pro forma restriction done to the utility model, every according to technical spirit of the present utility model; to any simple modification done by above embodiment and equal change, all fall within protection domain of the present utility model.
