[0025] Here’s how it works:

[0026] First, the new device is placed at the required location and connected to the circuit;

[0027] Second, water is delivered to the water inlet pipe 6 by a water pump, and the water inlet pipe 6 delivers water to the inside of the filter box 51. After the water flows through the filter layer 51 for filtering, dust and impurities are filtered at the right end of the filter layer, and the filtered water flows to the static mixer 41 through the connecting pipe 42. By adjusting the opening width of the second electric regulating valve 44, the speed of the fertilizer addition flow can be controlled. The fertilizer flows to the connecting pipe 42 and mixes with the water flow. The static mixer 41 is used to allow the fluid to flow in the pipeline and impact various types of plate elements, increase the velocity gradient of the fluid laminar motion or form turbulence. The static mixer 41 divides the water flow and the fertilizer, moves the position, and re-merges, so that the water flow and the fertilizer are evenly mixed to form water and fertilizer flowing to the inside of the shell 1, achieving the effect of even mixing of water and fertilizer, and high efficiency, low energy consumption, small size, low investment, and easy continuous production. By adjusting the opening width of the first electric regulating valve 3, the flow rate of the liquid outlet pipe 2 is adjusted, and the water and fertilizer are delivered to the outside for spraying, so that the spraying effect is better;

[0028] Third, the internal fertilizer residual amount of the fertilizer box 71 is monitored by the capacitive liquid level sensor 74, and the feedback is given to the external controller to control the solenoid valve 73 to open, so as to facilitate the replenishment of the fertilizer inside the fertilizer box 71. By opening the buckle 55, the limit of the cover plate 52 is released, and the cover plate 52 can be removed by using the handle 54, which facilitates the removal of the filter layer 53 from the inside of the filter box 51, which is beneficial to the treatment of dust and impurities on the filter layer 53 to avoid affecting the filtering effect of the water flow.
