[0030] In this embodiment, see Figure 3The water divider 335 includes a first cylinder 301, a first truncated cone 302, a second cylinder 303, a third cylinder 304, and a fourth cylinder 305 which are coaxially arranged from front to back. A plurality of guide grooves 306 are arranged on the outer wall of the third cylinder 304 along the circumferential direction. Each guide groove 306 is distributed in a curve and passes through the front and rear end surfaces of the third cylinder 304. Specifically, the diameters of the first cylinder 301, the fourth cylinder 305, the second cylinder 303, and the third cylinder 304 decrease in sequence.

[0031] In this embodiment, see Figure 1 A plurality of fans 40 are arranged on the bracket 4, and the exhaust ports of the fans 40 are arranged downward. The wind force of the fans 40 can increase the flow speed of the atomized medicine, so that the medicine reaches the plant leaves faster, and at the same time prevent the high temperature environment in the greenhouse from causing a large amount of evaporation to consume the medicine, resulting in a waste of medicine, and having a good effect of saving medicine.

[0032] In this embodiment, see Figure 1 The bracket 4 includes a column 41 and a support tube 42. The two columns 41 are vertically arranged in the middle of the two ends of the greenhouse body 1. The support tube 42 is horizontally arranged at the upper ends of the two columns 41. A shaft seat 43 is arranged on the upper end of each column 41. The support tube 42 is rotatably supported by the shaft seat 43 arranged on the upper end of the column 41. A driven gear 44 is coaxially arranged at one end of the support tube 42. A driving gear 45 that can mesh with the driven gear 44 is arranged below the driven gear 44. A driving motor 46 is arranged on the column 41. The driving gear 45 is coaxially fixed on the output shaft of the driving motor 46. The driving gear 45 is driven by the output shaft of the driving motor 46 to rotate. The driving gear 45 is meshed with the driven gear 44 to drive the support tube 42 to rotate on the shaft seat 43 by a certain angle, so that the wind direction of the fan 40 and the spraying direction of the high-pressure atomizing nozzle 33 can be changed, so that the spraying distance of the high-pressure atomizing nozzle 33 is increased, and a larger range of spraying can be achieved by continuously changing the blowing direction of the spraying direction.

[0033] In this embodiment, see Figure 1The liquid supply hose 31 is connected to the spray pipe 32 through a liquid rotary joint 30. The liquid rotary joint 30 is an existing commercially available pipe connector. The liquid supply hose 31 is rotatably connected to the spray pipe 32 through the liquid rotary joint 3, so that when the spray pipe 32 rotates a certain angle, the liquid supply hose 31 can still continue to supply liquid to the spray pipe 32.

[0034] In addition, by providing negative pressure in the spray pipe 32 through the micro-spray pump 34, the liquid in the nozzle 331 of the high-pressure atomizing nozzle 33 can flow back to the spray pipe 32, so as to backwash the filter element 338 of the high-pressure atomizing nozzle 33 and flush the scale on the inner wall of the spray pipe 32, thereby preventing the high-pressure atomizing nozzle 33 and the spray pipe 32 from being blocked.

[0035] The micro-spray pump 34 is an existing commercially available device, model ARP12DC12 / 24, with a working positive pressure of 8-10Bar and a working negative pressure of -85KPa.

[0036] It can be seen from the above technical solution that when in use, the liquid medicine in the mixing tank 21 is pressurized by the high-pressure atomizing sprayer 5 and then supplied to the high-pressure atomizing nozzle 33 for spraying through the spray pipe 32. The liquid medicine enters the high-pressure atomizing nozzle 33, is first filtered by the filter element 338, and then dispersedly guided into the nozzle 331 through the multiple guide grooves 306 arranged on the outer wall of the third cylinder 304 of the water separator 335 to form a vortex, and the accumulated sand or scale in the nozzle 331 is washed, and then the liquid medicine is sprayed out from the nozzle 331, and the liquid medicine is driven by the atomizing sprayer 5. The motor 46 drives its output shaft to drive the driving gear 45 to rotate. The driving gear 45 and the driven gear 4 are meshed with each other to drive the support tube 42 to rotate a certain angle on the shaft seat 43, so that the wind direction of the fan 40 and the spraying direction of the high-pressure atomizing nozzle 33 can be changed, so that the spraying distance of the high-pressure atomizing nozzle 33 is increased. After the spraying is completed, the micro-spray pump 34 provides negative pressure to the spray pipe 32, and the residual liquid in the spray pipe 32 is extracted and discharged from the drain pipe 37 to prevent the accumulation of liquid in the spray pipe 32 from generating scale and clogging the pipe.
