Compared with the prior art, the spraying device disclosed by the utility model has the advantages as follows: a problem that electric resources are wasted because the traditional spraying device needs to be driven by electric energy to change a spraying direction is solved.

Description

Injection apparatus

Technical field

The utility model relates to the fluid ejection technique field, especially a kind of facility of the atomizing of liquids for gardening.

Background technology

Existing injection apparatus for plant irrigations such as gardening plants mainly contains two large classes, one class is to utilize various mechanically operated devices to realize spraying the control of luffing angle and injection direction, mechanical driving device by driven by motor is connected on the parent tube, the rotation of drive parent tube, to change injection direction, the inclination jet blower of injector head also connects mechanical driving device and arrives, and the driven by motor mechanical driving device changes the injection luffing angle of injector head.Another kind of is at the injector head of the injection parent tube installation of erectting with electronic devices such as laser sensors, utilize the range that electronic device gathers needs injection, and by mechanical driving device control injection luffing angle and injection direction, to realize the control to range of jet.This two classes injection apparatus does not all break away from needs hydraulic pressure power source--the engine of power consumption in addition, the change of controlling the injection apparatus injection direction and spraying luffing angle, so both increase the cost of laying power system, also greatly wasted the device resource of electric power energy and power system.

Summary of the invention

Problem to be solved in the utility model provides a kind of injection apparatus, needs electric power energy to change injection direction to solve existing injection apparatus, the problem of waste electric power resource.

In order to address the above problem, the technical solution of the utility model is: this injection apparatus, include parent tube, on the described parent tube injector head is installed, described injector head inner sleeve has a nozzle, described nozzle has a pipe, and the water inlet end of described pipe is provided with inside boss, and the water side of described pipe dwindles gradually; Be embedded with the spherical crown section of protruding described water side in the described pipe, described spherical crown section offers spray orifice, is provided with two or more balls in each duct of described spray orifice.

In the technique scheme, more specifically scheme can be: described injector head has a body, is connected by stage clip with described nozzle in the described body; The water side of described body is hinged with plate washer, is provided with torsion spring between described plate washer and the described body end face.

Further: the upper end of described parent tube is tilted to outer four the described injector heads that divergently are provided with equably.

Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:

1, the nozzle of this injection apparatus is embedded with the spherical crown section of protruding described water side in its body, the direction of its injection can be divergent shape; Spherical crown section offers spray orifice, be provided with two or more balls in each duct of spray orifice, the slight variation of hydraulic pressure can make water change the position of ball, namely change gap between ball and the ball and the gap between ball and the spray orifice cell walls, make through the discharge in these gaps and increase or reduce, can change the direction that water flies away, make all directions that the possibility that is injected into all be arranged.This injection apparatus can change the water outlet direction automatically, and the injection gross pressure is constant;

2, the particular design of the injector head of this injection apparatus can utilize hydraulic pressure by pressing nozzle to compress stage clip, makes the spherical crown section of nozzle automatically extrude injector head, and the baffle plate on the injector head is backed down by nozzle automatically; When spraying end, along with the reduction of spraying hydraulic pressure, the tension force of stage clip makes the nozzle return, and the elastic force of torsion spring closes baffle plate, guarantees that outside dregs can not fall into injector head;

3, the upper end of the parent tube of this injection apparatus divergently is provided with four described injector heads outside being tilted to equably, can avoid the injection dead angle at injector head rear portion, and can increase the range of main water column.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing enforcement:

Fig. 1, injection apparatus shown in Figure 2 include parent tube 1, and the upper end of parent tube 1 is tilted to outer four injector heads 2 that divergently are provided with equably by cross pipe, and such four injector heads 2 can enlarge spray regime simultaneously to spraying all around.

Fig. 3, injector head 2 shown in Figure 4, its internal sleeve has a nozzle, and injector head 2 has a body 21, is connected by stage clip 22 with described nozzle in the body 21; The water side of body 21 is hinged with three plate washers 28 by three hinges 26, is provided with three torsion springs 27 between these three plate washers 28 and body 21 end faces, and these three torsion springs 27 are separately positioned on three hinge 26 places.Like this, can utilize hydraulic pressure by pressing nozzle to compress stage clip 22, make the spherical crown section of nozzle automatically extrude injector head 2, the baffle plate 28 on the injector head 2 is backed down by nozzle automatically; When spraying end, along with the reduction of spraying hydraulic pressure, the tension force of stage clip 22 makes the nozzle return, and the elastic force of torsion spring 27 closes baffle plate 28, guarantees that outside dregs can not fall into injector head 2.

Fig. 3, Fig. 5, nozzle shown in Figure 6 have a pipe 23, and the water side of pipe 23 dwindles gradually, and the water inlet end of pipe 23 is provided with inside boss, in order to increase the area of accepting hydraulic pressure; Be embedded with the spherical crown section 24 of protruding described water side in the pipe 23, spherical crown section 24 offers spray orifice, makes the direction of its injection can be divergent shape, is provided with two or more balls 25 in each duct of described spray orifice.The spherical crown section 24 here has round mouth, be built-in with the circular spacer ring of two different-diameters in this round mouth zone, two circular spacer rings and the coaxial setting of round mouth, circular spacer ring and round mouth are connected and fixed by three dividing plates, dividing plate circular array centered by round mouth is arranged, dividing plate extends to the inwall of round mouth from the outer wall of small circular spacer ring, region separation between circular spacer ring and the round mouth is formed grid, each independently the lattice body namely form a spray orifice, each spray orifice that is positioned between two circular spacer rings is provided with two balls 25, each spray orifice that is positioned between the circular spacer ring in outer ring and round mouth inwall is provided with three balls 25, for avoiding ball in spray orifice, to fall out, inside and outside two ends at grid all are welded with rib, as shown in Figure 5.The slight variation of pressing can make water change the position of ball 25, namely change the gap between the spray orifice cell walls of gap between ball 25 and the ball 25 and ball 25 and spherical crown section 24, make through the discharge in these gaps and increase or reduce, can change the direction that water flies away, make all directions that the possibility that is injected into all be arranged.This injection apparatus can change the water outlet direction automatically, and the injection gross pressure is constant.
