Description

Adjustable rotary shower nozzle

Technical field

The utility model relates to industry and afforestation irrigation technique field, is specifically related to a kind of adjustable rotary shower nozzle.

Background technology

Rotary nozzle is the important tool of a kind of use in treegarden irrigation, by it, can continue to supply water to flowers, plants and trees.The active force of rotary nozzle in the market during by water flow jet drives shower nozzle to rotate, and utilizes the sheet of breaing up at exit portal, and continuous current are broken up, and realizes the sprinkling irrigation of certain area.

But, these shower nozzles can only spray covering circular area, the vegetation Shi edge that is square or other shapes at spray area can cause the source waste of water, if water is sprayed to the normal walking that road also affects pedestrian simultaneously, can only to given area or region, realize all standing by arranging of complexity.Patent CN101716563 discloses a kind of shower nozzle based on frequency conversion unit control method, adopts frequency control way to carry out speed regulating control to spray water pump assembly, reaches the object that changes spray area; But clearly, this mechanism is too complicated and easily break down.Patent CN1068800C discloses a kind of sprinkler that utilizes changeable-shaped cam face to change maximum water spray distance, but because its main purpose is the stability that guarantees that sprinkler is stopped over, mechanism is very complicated.

Utility model content

In order to solve the problems of the technologies described above, the utility model provides a kind of adjustable rotary shower nozzle, simple and reasonable, and design cost is low, easy to use, and can realize the control of spray angle and sprinkling distance.

In order to achieve the above object, the technical scheme that the utility model adopts is, a kind of adjustable rotary shower nozzle, comprise base, described base is provided with a strut, on strut, the position at this inner core top is provided with a bearing relatively, in this bearing, plug a cross bar, described inner core top is provided with a bevel gear wheel, the sheathed bevel pinion in position of relative this bevel gear wheel on described cross bar, described bevel pinion and bevel gear wheel engagement, on described cross bar, be also provided with cam, on described cam, there is a connecting rod, the upper end of connecting rod is connected with shower nozzle by hinge, lower end withstands in the groove of cam.

Further, described base consists of the inner core coaxially arranging and urceolus, and urceolus is stretched out at described inner core top, a sheathed strut in described inner core.

Further, on described inner core and outer tube wall, offer the through hole of coupling, by latch, insert the through hole of this inner core and urceolus and can realize the adjusting of inner core and urceolus relative altitude, and then regulate the height of whole base.

Further, the gearratio of described bevel gear wheel and bevel pinion is 1:4.

The utility model is by adopting technique scheme, and compared with prior art, tool has the following advantages:

The utility model is by being hinged on shower nozzle on strut, and this shower nozzle is connected to a cross bar by a connecting rod and a cam, this cross bar is provided with a bevel pinion, this bevel pinion and the bevel gear wheel engagement being arranged on base, during use, active force while utilizing current outgoing, drives strut axial-rotation, and then drives cross bar to rotate around strut axis.The bevel gear wheel when bevel pinion on cross bar rotates and on base is intermeshing, produces active force and drives cross bar around self axis rotation.Now, be fixed on the also rotation in the lump of cam on cross bar.Connecting rod is done upper and lower periodic motion under actuated by cams, and then the shooting angle of Control Nozzle, also by corresponding regular movement.And then realize the object that changes current shooting angle and range, thereby realized the change of the irrigation area of current.

The specific embodiment

Now with the specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.

As a specific embodiment, as depicted in figs. 1 and 2, a kind of adjustable rotary shower nozzle of the present utility model, comprise base 1, described base 1 consists of the inner core 11 coaxially arranging and urceolus 12, urceolus 12 is stretched out at described inner core 11 tops, the interior sheathed strut 2 of described inner core 11, on strut 2, the position at these inner core 11 tops is provided with a bearing 3 relatively, in this bearing 3, plug a cross bar 4, described inner core 11 tops are provided with a bevel gear wheel 3 ', the sheathed bevel pinion 3 in position of relative this bevel gear wheel 3 ' on described cross bar 4, described bevel pinion 3 and bevel gear wheel 3 ' engagement, on described cross bar 4, be also provided with cam 5, on described cam 5, be connected with a connecting rod 6, described strut 2 tops are hinged with a nozzle 7 by a hinge 21, described nozzle 7 ends are fixedly connected with connecting rod 6.On described inner core 11 and urceolus 12 walls, offer the through hole 10 of coupling, the through hole 10 that inserts this inner core 11 and urceolus 12 by latch 9 can be realized the adjusting of inner core 11 and urceolus 12 relative altitudes, and then regulates the height of whole base 1.Extract latch 9 and can realize the integral body of epimere shower nozzle and move up and down, Fixed latches 9 can the whole elemental height of adjusting shower nozzle at different through holes 10 places, and then changes the difference of ejection area.

The gearratio of described bevel gear wheel 3 ' and bevel pinion 3 is 1:4, by these large bevel pinion 3 gearratios, whole shower nozzle is turned around, and on bevel pinion 3, related cross bar 4 and the cam 5 being fixed thereon turn four circles, thereby make shower nozzle can spray foursquare spray area.

With regard to shower nozzle, spraying square spray area is below that example describes the adjusting that shower nozzle of the present invention can be realized spray angle and spray distance in detail, and particularly, as shown in Figure 3, establishing the square length of side is 2a, from the angle of initial edge run-out, is ω.There is range

$X=\frac{\mathrm{\α}}{\cos \mathrm{\ω}}---(1-1)$

As shown in Figure 4, ignore the height of base 1 buried part, the rotation circle centre position height of establishing shower nozzle is zero point, and current be take V as speed, and θ is angle ejection, and the distance of ejection is X.By the rule of oblique upper paraboloiding movement be easy to get into:

$X=\frac{v^2\sin 2\mathrm{\θ}}{g}---(1-2)$

When connecting rod 6 is cam 5 base radius while starting to move upward from minimum point, the height that the cam 5 basic circle centers of circle increase to connecting rod contact is h again, and contact is b(given data to the distance of shower nozzle central shaft, is designed to 3cm), have

$\tan \mathrm{\θ}=\frac{h}{b}---(1-3)$

So, on foursquare limit, get different points and obtain different angle ω, by 1-1, can calculate the range X of current, know that X just can calculate the angle θ that needs the required inclination of jet pipe by 1-2, finally utilize 1-3 just can determine the lift h of connecting rod on cam 5, just can determine thus the shape of cam 5 while spraying square lawn.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; within not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
