The utility model discloses a beneficial effect is: this scheme adopts the high -speed helical motion of taking tapered shower nozzle core to realize high -pressure liquid medicine, adopts the mode of processing helicla flute to compare with traditional vortex core formula shower nozzle, is satisfying to under the atomizing effect of high -pressure liquid medicine the simple structure of this scheme, production convenient to use.
Description
Technical field
This utility model relates to the shower nozzle of spraying machine, is specially a kind of centrifugal sprinkler on spraying machine.
Background technology
Spraying machine refers to and medicinal liquid is applied certain pressure, medical liquid atomizing is made to become droplet a kind of machine being sprayed onto on crops by shower nozzle, spraying function makes to be atomized into the liquid medicine jet of droplet farther out, and the ratio of distribution is more uniform, good and climate the impact of cohesiveness is less, therefore medicinal liquid can cover on crops preferably, and the medicine school of medicinal liquid is lasting.
When spraying machine carries out medicine liquid spray, sprinkler performance quality will directly influence the prevention effect to diseases and pests of agronomic crop, when spray value is identical, the diameter of droplet is more little, and the number of droplet is also more many, and the area coverage of medicinal liquid is big and uniform, the loss of medicinal liquid is few, and prevention effect is good.Therefore, shower nozzle is that the important process parts of spraying machine, its structure and working condition will have influence on the atomization of medicinal liquid, discharge rate, spraying swath, range and injection direction etc..
The shower nozzle used on current spraying machine mostly is vortex flow core type shower nozzle, and this shower nozzle is in order to meet the eject request of medicinal liquid, and on sprayer body, processing has some skewed slots with helical angle, and this makes the structure complexity of whole shower nozzle, and production and application is inconvenient.
Utility model content
This utility model is intended to provide a kind of simple in construction, and production and application is conveniently used for the centrifugal sprinkler on spraying machine.
The centrifugal sprinkler on spraying machine in this programme, including feed tube and sprayer body, feed tube place is provided with the flow channel for liquids tapered into along high pressure medicinal liquid direction of advance cross section, and sprayer body place is provided with the first groove, flow channel for liquids and the first groove and communicates, the sprinkler core of tapering it is provided with in first groove, the top of sprayer body is provided with spray nozzle sheet, spray nozzle sheet offers spray orifice, spray orifice and the first groove and communicates, the top of spray nozzle sheet is additionally provided with sprinkler cap, and sprinkler cap presses spray nozzle sheet and is connected with sprayer body.
nullThe principle of this programme is: when carrying out the sprinkling of medicinal liquid，High pressure medicinal liquid enters the flow channel for liquids on feed tube，Owing to flow channel for liquids tapers in the cross section of high pressure medicinal liquid direction of advance，Therefore the flow velocity of high pressure medicinal liquid will be gradually increased，Now the tangential direction along flow channel for liquids is entered in the first groove of sprayer body by high pressure medicinal liquid，The high pressure medicinal liquid entered in the first groove will do high-speed screw motion around the sprinkler core with tapering，When high pressure medicinal liquid is close to the spray orifice on spray nozzle sheet，Owing to the radius of gyration reduces，Then the peripheral speed of high pressure medicinal liquid becomes much larger，The high pressure medicinal liquid particle sprayed by spray orifice has two kinds of speed: one is parallel to the pace of orifice center line，One is the pivotal tangential velocity of high speed，Both aggregate velocities are the direction of motion that high pressure medicinal liquid particle is actual，This direction of motion and orifice center line have angle，This angle is the atomizing angle of shower nozzle，Therefore，After the ejection of high pressure medicinal liquid blowing hole，The dispersion shape thin film with tapering will be become，The thin film more remote apart from spray orifice is more thin so that fragmenting into fragment，And then it is condensed into droplet，This droplet further hits against with the air of geo-stationary and forms less droplet，It is sprayed onto on crops.
This programme provides the benefit that: this programme adopts the sprinkler core with tapering to realize the high-speed screw motion of high pressure medicinal liquid, compared with adopting processing spiral fluted mode with tradition vortex flow core type shower nozzle, under meeting the effect to high pressure medical liquid atomizing, the simple in construction of this programme, production and application is convenient.
Further, in order to the connection making feed tube and outside spray boom is reliable and both convenient disassemblies, feed tube offering screw thread, feed tube is threadeded with outside spray boom.
Further, in order to prevent high pressure medicinal liquid from coordinating leakage from spray nozzle sheet and sprayer body, the gasket seal preventing liquid leakage between sprayer body and spray nozzle sheet, it is additionally provided with.
Further, the both sides of sprinkler cap are additionally provided with diffusion sheet, and loading onto the diffusion sheet high pressure medicinal liquid to ejection has and certain block effect, so that the droplet being uniformly scattered near shower nozzle crops nearby, what increase shower nozzle sends area forth.
