Abstract
The invention relates to a low-volume spray head of a sprayer duster. The low-volume spray head is provided with a low-volume spray pipe, wherein a connecting piece is arranged on the upper end of a liquid conveying pipe of the low-volume spray pipe; the connecting piece is connected with a low-volume nozzle; the outer wall of the connecting piece is provided with a vane wheel through a bearing; vanes are arranged on the vane wheel; the upper end of the vane wheel is provided with a nozzle cap; water throwing holes are formed on the upper edge of the nozzle cap; and the inner chamber and the water throwing holes of the nozzle cap are communicated with water outlet holes and the liquid conveying pipe of the low-volume nozzle. Droplet particles which are finally sprayed on farm crops are extreme small after pesticide liquid in the nozzle is collided and primarily scattered at the inner wall of the nozzle cap spread from the center of the inner chamber of the nozzle cap to the outside and thrown out of the water throwing holes under centrifugal force and wall attachment effect, and further smashed by a high-speed air flow and the like, so the atomization effect is good; as the droplets are very light, the droplets can be sent further by the air flow, and are easy to adhere to the surface of stems and leaves and body surfaces of insects; and the low-volume spray head of the sprayer duster reaches larger spraying covering area and better insecticidal effect, and reduces environmental pollution at the same time.
Description
Technical field
The present invention relates to shower nozzle, relate in particular to a kind of low-volume spray head of sprayer duster, belong to the agricultural plant protection field of mechanical technique.
Background technology
When giving the crops pesticide, if the drop particle of ejection is bigger, drop is as easy as rolling off a log in the effect lower edge of self gravitation crops stem, leaf surface landing so, not only reduce the agricultural chemicals utilization rate, pollute surrounding environment, and insecticidal effect is poor.Be head it off, once the someone designed the shower nozzle that the drop particle is less, atomizing effect is good of ejection, as China Patent No. is that the patent document of ZL200820031789.7 discloses a kind of ULV nozzle, it comprises spout, be arranged on the branch flow cone in the spout, pass the drug liquid tube of spout, with an impeller that is rotationally connected that passes the branch flow cone; The blade of impeller is distributed in the big end periphery of branch flow cone, has fluid hole on minute drug liquid tube tube wall of flow cone small end punishment flow cone outside; During use the discharge pipe of shower nozzle and sprayer-duster is joined, high velocity air is blown into spout, guide vane through minute flow cone, impeller is a high speed rotating, soup is blowed to the big end of branch flow cone by high velocity air after fluid hole flows out simultaneously, the impeller that is rotated at a high speed further smashes, tears again, forms thin and uniform droplet.But this shower nozzle does not have micro-nozzle, does not have fluidic device, only depends on soup switch control liquid outlet quantity, flow-control is accurate inadequately, flow is bigger than normal, and the not rotation of the fluid hole of this shower nozzle, though its outside at minute flow cone is evenly distributed with a plurality of fluid holes, but under the effect of gravity, liquid fails to be convened for lack of a quorum and flows out from following hole, causes each fluid hole mass flow discrepancy even, and droplet is also inhomogeneous, liquid stream is only through the shunting of fluid hole and smashing, tearing of impeller simultaneously, and its atomizing effect is limited.
Summary of the invention
The objective of the invention is the shortcoming that exists at prior art, provide a kind of ejection droplet little and even, contact with the blade face effective, deinsectization efficient height, minimizing liquid waste and the little low-volume spray head of sprayer duster of pollution on the environment.
The technical solution adopted in the present invention is to achieve the above object of the invention:
Low-volume spray head of sprayer duster, has low amount jet pipe, low amount jet pipe center is shaped on woven hose, woven hose is connected by the housing of gusset with low amount jet pipe, connector is installed in the woven hose upper end that it is characterized in that low amount jet pipe, connector connects low flow nozzle, the connector outer wall is installed impeller by bearing, be shaped on blade on the impeller, cap of spraying nozzle is installed in described impeller upper end, the cap of spraying nozzle upper edge is shaped on the water dumping hole, and the inner chamber of described cap of spraying nozzle is connected with the apopore and the woven hose endoporus of water dumping hole and low flow nozzle.
The present invention relates to a kind of low-volume spray head of sprayer duster, has low amount jet pipe, low amount jet pipe center is shaped on woven hose, woven hose is connected by the housing of gusset with low amount jet pipe, connector is installed in the woven hose upper end that is characterized in low amount jet pipe, connector connects low flow nozzle, the connector outer wall is installed impeller by bearing, be shaped on blade on the impeller, cap of spraying nozzle is installed in described impeller upper end, the cap of spraying nozzle upper edge is shaped on the water dumping hole, and the inner chamber of described cap of spraying nozzle is connected with the apopore and the woven hose endoporus of water dumping hole and low flow nozzle.During use the discharge pipe of this shower nozzle with sprayer-duster joined, high velocity air is blown into low amount jet pipe, impeller drives cap of spraying nozzle and rotates at a high speed under the blade effect, soup impinges upon on the cap of spraying nozzle inwall from the apopore ejection of hanging down flow nozzle and is tentatively broken up, because cap of spraying nozzle is in the high speed rotation status, therefore the soup of being broken up also and then spread laterally from the cap of spraying nozzle lumen centers under the effect of centrifugal force and wall attachment effect by the rotation while, and throw away and form thinner water column from the shunting of the water dumping hole of cap of spraying nozzle, open in the upper edge of cap of spraying nozzle in the water dumping hole can prevent that the soup of being broken up from merging together again, helps soup is in time thrown away; The thin water column that throws away is further smashed by the high velocity air in the low amount jet pipe, thereby forms tiny droplet.The soup of this shower nozzle is tentatively broken up through impinging upon the cap of spraying nozzle inwall, under the effect of centrifugal force and wall attachment effect, spread laterally and throw away from the shunting of the water dumping hole of cap of spraying nozzle from the cap of spraying nozzle lumen centers, very little by the droplet particle that is sprayed onto at last on the crops under the triple roles such as high velocity air further smashes, droplet is even, therefore atomizing effect is good, because this little droplet is very light, therefore sent fartherly by air-flow, and stick to stem easily, the body surface of leaf surface and insect, thereby reach bigger spraying area coverage and better insecticidal effect, reduced soup surface subsidence simultaneously and improved operating efficiency and the agricultural chemicals utilization rate, reduced pollution surrounding environment.
For being threaded, low flow nozzle is provided with sealing ring outward between described low flow nozzle and the connector, and sealing ring seals mutually with the top end face of connector, makes between low flow nozzle and the connector to reach the better seal effect.
Described blade is the 2-8 sheet, is distributed on the impeller, can guarantee that impeller is in the high speed rotation status, and blade is many more, and wheel speed is high more, and centrifugal force is big more.
Described water dumping hole is 6-20, is distributed on the upper edge of cap of spraying nozzle, and the water dumping hole is many more, and atomizing effect is good more.
Described connector can be made one with low flow nozzle, also can make one with woven hose, improves sealing effectiveness.
Described cap of spraying nozzle front end is shaped on the hexagon endoporus, and described low flow nozzle outer wall is a hexagon, and the hexagon endoporus matches with the outer wall of the low flow nozzle of hexagon; Cap of spraying nozzle can be worked as the instrument use when flow nozzle is hanged down in dismounting.
