Abstract
The utility model discloses a super low-speed rotating injecting head composed of an injecting nozzle disc, an injecting head body, a static blade wheel, an injecting head seat, a bearing outer race, a bearing inner race, a bearing, a sealing ring and a water inlet pipe. The static blade wheel and the injecting head body are provided with liquid brakes and the liquid brakes reduce the rotating speed. The firing range of the pressure water is full utilized and the injecting area is enlarged. The super low-speed rotating injecting head can be used for the injecting operation of the farmland, the vegetable plot, the orchard, the nursery, the flower bed, the lawn, the athletic field, etc.
Description
The Ultra-Low Speed rotary nozzle belongs to the flusher with movable spout member.
Shower nozzle is the vitals in the sprinkling machine, and in the irrigation operation of watering, water is injected into vaporific or water droplet through piping by shower nozzle by certain pressure, drops onto garden, nursery, field or sports ground, ground such as lawn.Existing shower nozzle has rocker-arm, swing type, rotary etc. multiple, and rotating sprinkler is to utilize the propulsive thrust square of press water high velocity jet to make the shower nozzle rotation, thereby reach water is sprayed onto on the circular sprinkling irrigation place uniformly.Rotating sprinkler is simple in structure, easy to use, is widely used in sprinkling irrigation operations such as lawn, flower bed, vegetable plot.But, the outstanding problem of existing rotating sprinkler is that rotating speed is too fast, rotary speed is offset jet velocity, therefore range is little, spray area is limited, if seek out the effect that remote large tracts of land is sprayed, must add the pressure and the water velocity of big flood, the thing followed is bound to such an extent that strengthen the structural strength that pipeline, joint, sprinkler shower nozzle etc. are located, and cost is improved.
The purpose of this utility model is to provide a kind of hydraulic brake that has in rotating sprinkler, rotating speed is low, the shower nozzle of large tracts of land spraying operation.
Technical solution of the present utility model is: the Ultra-Low Speed rotary nozzle is made of rotary part and stationary parts, and rotary part is to be fitted on the nozzle body by the nozzle dish, constitutes with being threaded with the nozzle block that bearing outer ring is housed again.Stationary parts is by bearing inner race being housed and with the water inlet pipe that is being threaded on the stationary blade wheel, in the middle of bearing inner race and bearing outer ring bearing is housed and sealing ring constitutes.In the middle of rotary part and stationary parts, there are hydraulic brake, hydraulic brake to be constituted by toroidal cavity on the stationary blade wheel and the toroidal cavity on the sprayer body.Uniform blade is evenly equipped with paired nozzle on the nozzle dish in toroidal cavity, and every pair of nozzle symmetry is on same center line, and nozzle is measure-alike, and jet angle α equates.Nozzle is vertically upward arranged on nozzle.
The utility model has the advantages that: press water is in the propulsive thrust square effect lower nozzle rotation of injection water, the hydraulic brake that toroidal cavity on the sprayer body and the toroidal cavity on the stationary blade wheel constitute, the hydraulic brake effect has been played in the rotation of shower nozzle, make shower nozzle with very low rotating speed rotation, thereby make full use of the range of press water, enlarge spray area, during the shower nozzle rotation, the current that different jet angles spray form the pattern of definite shape in air, be used for ground such as lawn, flower bed when shower nozzle, can bring a kind of impression of U.S. to the people.
Below in conjunction with accompanying drawing the utility model specific embodiment is described in further detail.
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the cutaway view of nozzle shown in Figure 2 along the B--B line:
Fig. 1 is a structure chart of the present utility model, and nozzle dish 1 press-fits with nozzle body 2 and is integral.The bearing outer ring 5 that is assemblied in the nozzle boss 4 is loaded onto bearing 7 and sealing ring 8, again with bearing inner race 6 assemblings that are pressed with stationary blade wheel 3, water inlet pipe 9 is screwed on the stationary blade wheel 3, couples together, promptly constituted the Ultra-Low Speed rotary nozzle with the internal thread on external screw thread on the nozzle boss 4 and the nozzle body 2.
From Fig. 2 and Fig. 3 as can be known, nozzle 10 is on the center line in the garden that is distributed in pairs, and every pair of nozzle symmetry is on same center line, and is and measure-alike, and jet angle α equates.Jet angle α is according to the different requirements of spraying, and its angle can be selected arbitrarily, and the optimum range of its jet angle α is at 40 degree--between 65 degree.Nozzle 11 is vertically upward arranged near the nozzle dish 1 close garden heart.
During use, water inlet pipe 9 and water source are connected, current are full of the cavity of hydraulic brake and nozzle body 2 along water pipe, eject from nozzle 10,11.
The Ultra-Low Speed rotary nozzle can be used for the spraying operation on ground such as vegetable plot, orchard, nursery, lawn, flower bed, sports ground.
