The routine techniques knowledge in field can determine its main body formed with axle sleeve 61, hollow shaft 63, sprinkler body bend pipe 66 and jet pipe 617
The connection relation of structure.
The operation principle of rocker-arm single injector nozzle of the present invention is that the rotation of nozzle is driven using rocking arm, work
The mutual motion process transmitted and convert of different-energy when being rocking arm work on spirit.The work of rocker-arm single injector nozzle
Work is divided into following five stages：
(1) startup stage：The deflector of water jet directive air deflector ejected from nozzle 615 turns to 60 ° extremely
120 °, deflector obtains the reaction force of jet stream, and rocking arm is made to obtain kinetic energy and swing out, priming lever spring is reversed, is turned round
Torque, torsional moment is less than the moment of reaction of jet stream, so rocking arm obtains angular speed and is detached from jet stream.
(2) stage is put outside：Inertia force is rotated further rocking arm, until rocking arm subtended angle reaches maximum, so as to obtain maximum
Torsional moment, at this time angular speed be changed into 0, spring potential energy obtains maximum, i.e., the kinetic energy put outside rocking arm is completely converted into the bullet of spring
Property potential energy.
(3) it rebounds the stage：Under the action of spring torsion square, the rotation that the elastic potential energy of spring is gradually converted into rocking arm is moved
Can, rocking arm starts toward backswing, and angular speed is constantly increasing, until rocking arm will cut jet stream.
(4) enter the water stage：Again into incident flow, deflector starts to receive water at first rocking arm with maximum rotation kinetic energy
Stream, the reaction force of generation sharply increase rocking arm kinetic energy, and angular speed becomes increasing.
(5) impact phase：Rocking arm is under the action of revolution inertia force and the tangential additional force of deflector, with very big angular speed
Start to hit jet pipe, nozzle is made to rotate 3 ° to 5 °, after collision, rocking arm completes a complete rotational movement process.
Under the action of moment of friction, nozzle is static quickly to have stopped getting off.Hereafter continue to repeat above-mentioned rotational movement process.
The basic parameter of rocker-arm single injector nozzle has water inlet diameter, nozzle diameter, operating pressure, water spray and penetrates
Journey.Under the premise of operating pressure and nozzle diameter determine, water spray is big to illustrate that nozzle is efficient, and the head loss of nozzle is small,
Nozzle exit pressure is larger.Generally use discharge coefficient represents sprinkler performance, the stream of rocker-arm single injector nozzle of the present invention
Coefficient of discharge is more than 0.9.The range of rocker-arm single injector nozzle is defined as under calm condition, and during normal work, amount bucket is per small
When the depth of water collected be that point of 0.25mm to the horizontal distance of nozzle rotation center.Rocker-arm single injector of the present invention
Nozzle avoids after flow enters nozzle and disturbs, reduce whirlpool due to being provided with sprinkler body bend pipe 66 and flow straightener 616
It generates, the closely knit aeration of overflow is few when being come out from nozzle, and surface is smooth, and the flow turbulence in flow is few, eliminates main water
Collision between molecule and its between tube wall, effectively eliminates cross current, and the range for making nozzle is long, and friction loss is small, spray
Velocity field at mouth is evenly distributed, and resistance to water-flow loss is small.
As shown in figure 3, the hydroturbine 9 includes water inlet 11 and water outlet 17, water inlet 11 and water outlet 17 it
Between be provided with valve 10.
The water inlet 11 of the hydroturbine 9 is connected by water inlet pipe with hydrant；Water outlet 17 passes through pipeline and hose 4
Connection.
As shown in Figure 1, the locomotive 7 further includes multiple wheels 8, multiple wheels 8 are connected to the bottom of locomotive 7.
Sprinkler with reel of the present invention with rocker-arm single injector nozzle when in use, first will by tractor
Reel vehicle 2 is dragged to the suitable position in farmland, and locomotive 7 is dragged to the another of farmland along the practical trend in crops in farmland
The valve on hydrant is opened at end, is passed water through water inlet 11, valve 10, water outlet 17, hose 4 and is entered hydraulic giant 5, nozzle 6,
Water spray realizes the sprinkling irrigation to crops farmland outward, while hydroturbine 9 drives reel 3 to rotate, and hose 4 is same on reel 3
When locomotive 7 pulled into reel 3.The structure of hydroturbine 9 belongs to the prior art, naturally it is also possible to pass through hydraulic pressure of the prior art
The driving devices such as cylinder driving device, rubber pocket, backpulsing water wheels or petrol engine water pump provide driving force for the rotation of reel 3.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention belong to the scope of protection of present invention.
