Detailed Description

The present invention will be described in detail with reference to the following embodiments and accompanying drawings.

The spraying system of this embodiment, as shown in fig. 1 and fig. 2, including water supply module, supply medicine module, medicine mixer 1 and nozzle 5, medicine mixer 1 is including the feed liquor pipe 11, mixing tube 12 and the drain pipe 13 that connect gradually, and threaded connection feed liquor pipe 11 and drain pipe 13 are respectively distinguished at the both ends of mixing tube 12, and nozzle 5 communicates drain pipe 13. The mixing tube 12 is provided with a medicine mixing cavity 121, a plurality of light elastic spheres 14 are contained in the medicine mixing cavity 121, and the spheres 14 occupy the volume 1/3-2/3 of the medicine mixing cavity 121. The both ends of mixing tube 12 are equipped with filter screen 15, and filter screen 15 mesh diameter is not more than the aperture of nozzle 5, also is not more than spheroid 14 diameter, and filter screen 15 can prevent that spheroid 14 from being washed out medicine mixing chamber 121, can also filter the impurity in the mixed pesticide simultaneously, prevents that nozzle 5 from blockking up. The water supply module comprises a water tank 21, a water pump 22 and a first throttle valve 23, a water inlet of the water pump 22 is communicated with the water tank 21, and a water outlet of the water pump 22 is communicated with the liquid inlet pipe 11 of the medicine mixer 1 after being communicated with the first throttle valve 23. The medicine supply module comprises a medicine box 31, a medicine pump 32 and a second throttle valve 33, an inlet of the medicine pump 32 is communicated with the medicine box 31, and an outlet of the medicine pump 32 is communicated with the liquid inlet pipe 11 of the medicine mixer 1 after being communicated with the second throttle valve 33. The drug pump 32 is a metering pump with small flow, low energy consumption and easy operation and capable of accurately controlling the flow, or the drug pump 32 is a piezoelectric pump. The tapered hole is arranged in the liquid inlet pipe 11, so that the speed of water and pesticide flowing into the pesticide mixing cavity 121 can be increased, the ball 14 can oscillate more violently, and the water and the pesticide can be mixed more uniformly. The above-mentioned communication is realized by a pipeline.
