Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of shower nozzle of plant protection unmanned plane sprayer.
It is the structural representation of the shower nozzle of the utility model plant protection unmanned plane sprayer referring to figs. 1 to 4, Fig. 1; Fig. 2 is the exploded perspective view of the shower nozzle of the utility model plant protection unmanned plane sprayer; Fig. 3 is the front view of centrifugal pan in the shower nozzle of the utility model plant protection unmanned plane sprayer; Fig. 4 is the top view of centrifugal pan in the shower nozzle of the utility model plant protection unmanned plane sprayer. The shower nozzle of a kind of plant protection unmanned plane sprayer that the present embodiment provides. The shower nozzle of this plant protection unmanned plane sprayer comprises: brushless electric machine 1, centrifugal pan 2, diversion cavity upper cover 3 and diversion cavity lower cover 4. Wherein, centrifugal pan 2 comprises: for storing the inner chamber of liquid, the sidewall of inner chamber is provided with some liquid through-holes 21 for spray liquid. Diversion cavity upper cover 3 is oppositely arranged with diversion cavity lower cover 4 and coordinates installs to form diversion cavity (not shown). The central shaft 22 of centrifugal pan 2 is fixedly connected with the rotating shaft 13 of brushless electric machine 1. Diversion cavity upper cover 3 comprises: the liquid joint 31 being communicated with liquid storage device (not shown), and with the first through hole (not shown) of rotating shaft 13 adaptations of brushless electric machine 1. Diversion cavity upper cover 3 is fixedly mounted in the foot rest (not shown) of plant protection unmanned plane. Brushless electric machine 1 is fixed on diversion cavity upper cover 3 tops. Diversion cavity lower cover 4 and the first through hole correspondence position are provided with the second through hole (not shown), and the rotating shaft 13 of brushless electric machine 1 runs through the first through hole, the second through hole is fixedly connected with the central shaft 22 of centrifugal pan 2. The inner chamber of centrifugal pan 2 is communicated with diversion cavity through the second through hole. Between diversion cavity lower cover 4 and centrifugal pan 2, there is gap. Preferably, the gap between diversion cavity lower cover 4 and centrifugal pan 2 is 1 ~ 3mm. In the present embodiment, brushless electric machine 1 rotates with the speed of 30000r/min per minute.
The driven unit that brushless electric machine 1 rotates as centrifugal pan 2, this brushless electric machine 1 comprises: motor outer rotor 11, motor stator 12 and rotating shaft 13. When installation, motor stator 12 is fixedly mounted on the top of diversion cavity upper cover 3 by screw. The first through hole, the second through hole of diversion cavity lower cover 4 and the central shaft 22 of centrifugal pan 2 that the rotating shaft 13 of brushless electric machine 1 runs through diversion cavity upper cover 3 are fixedly connected with. In the time that brushless electric machine 1 rotates, centrifugal pan 2 is also being followed and is being rotated.
Centrifugal pan 2 comprises: inner chamber, central shaft 22 and liquid through-hole 21. The central shaft 22 of centrifugal pan 2 is fixedly connected with the rotating shaft 13 of brushless electric machine 1. Liquid in liquid storage device flows into the inner chamber of centrifugal pan 2 through diversion cavity. In the time that centrifugal pan 2 rotates, centrifugal pan 2 is inner can produce negative pressure, thereby air and liquid are drawn in centrifugal pan 2 simultaneously. Liquid is thrown out of and becomes brin and be linked to be film under the effect of high speed centrifugation power, along with liquid film is outwards extended to thinner liquid film, and friction occurs and be separated into atomization shape with very high speed and ambient air. Therefore, the utility model does not need additionally liquid to be pressurizeed, and liquid can be delivered to centrifugal pan 2 inner chambers yet and spray away. In addition,, because the rotor of plant protection unmanned plane can produce downward air-flow when rotated, air-flow can take the liquid after atomization to be sprayed target.
Diversion cavity upper cover 3 coordinates to form diversion cavity with diversion cavity lower cover 4, and diversion cavity upper cover 3 is fixedly connected with diversion cavity lower cover 4. Diversion cavity upper cover 3 is fixedly connected with the foot rest of plant protection unmanned plane by screw. Between diversion cavity lower cover 4 and centrifugal pan 2, there is gap. In the time that plant protection unmanned plane contacts to earth, brushless electric machine 1 in the vertical direction is stressed and up move, so that centrifugal pan 2 can be contacted on diversion cavity lower cover 4. Owing to being fixedly connected with diversion cavity upper cover 3 to diversion cavity lower cover 4, and diversion cavity upper cover 3 is directly fixed on the foot rest of plant protection unmanned plane. Therefore, the foot rest of plant protection unmanned plane can be stressed, thereby shed the impulsive force of the rotating shaft 13 of brushless electric machine 1, thereby can prevent that brushless electric machine 1 rotating shaft 13 from becoming curved. After external force disappears, and plant protection unmanned plane built on stilts, the strong magnetic in the rotor in high-speed brushless motor 1 can adsorb back rotor original position, and centrifugal pan 2 is ejected simultaneously. In addition, the liquid joint 31 of diversion cavity upper cover 3 is communicated with liquid storage device. Liquid in liquid storage device flows in diversion cavity through liquid joint 31, and flows into centrifugal pan 2 from diversion cavity again. It should be noted that liquid in diversion cavity the second through hole in diversion cavity lower cover 4 flow to the inner chamber of centrifugal pan 2. Further, in order to allow liquid in diversion cavity can flow to more rapidly the inner chamber of centrifugal pan 2, diversion cavity lower cover 4 also comprises: extend towards centrifugal pan 2 directions the mozzle 41 forming by the second through hole. It should be noted that mozzle 41 arranges in a tubular form.
The plant protection unmanned plane that the utility model provides sprays the shower nozzle of device, and the brushless electric machine 1 in this shower nozzle drives centrifugal pan 2 to run up, and makes the inner negative pressure that produces of centrifugal pan 2, and liquid flows in centrifugal pan 2 under the effect of pressure. Therefore, the utility model does not need additional device for exerting also can realize medical liquid atomizing and spray, thereby has prevented that medicine from dripping obstruction. On the other hand, in the time that plant protection unmanned plane contacts to earth, brushless electric machine 1 is stressed and up move, and centrifugal pan 2 contacts at diversion cavity lower cover 4, because diversion cavity lower cover 4 is fixedly connected with the diversion cavity upper cover 3 that is fixed on plant protection unmanned plane foot rest. Therefore, plant protection unmanned plane foot rest has been born external force, sheds the impulsive force of the rotating shaft 13 of brushless electric machine 1, thereby prevents the stressed bending of rotating shaft 13 of brushless electric machine 1.
Further, centrifugal pan 2 is the setting of bamboo hat shape, and centrifugal pan 2 back-offs are installed in the rotating shaft 13 of brushless electric machine 1.
Further, some liquid through-holes 21 are evenly located at the top position of centrifugal pan 2. Usually, liquid through-hole 21 is generally provided with 40, and 40 liquid through-holes 21 equidistantly distribute.
Further, for improving the spraying efficiency of shower nozzle, centrifugal pan 2 inner chambers are provided with some guiding gutters 23, and some guiding gutters 23 are turbine leaf-shaped distribution. Preferably, a liquid through-hole 21 is connected with a guiding gutter 23.
These are only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
