It also includes a feeding mechanism and a mixing mechanism; the mixing mechanism includes a mixing tank, a stirring structure, a water outlet branch pipe, and a fertilizer feeding branch pipe. One end of the water outlet branch pipe is connected to the water outlet pipe of the pump body, and the other end is connected to the top of the mixing tank. One end of the fertilizer feeding branch pipe is connected to the bottom of the mixing tank, and the other end is connected to the water inlet pipe; the feeding mechanism inputs fertilizers into the mixing tank, and the stirring structure stirs the materials in the mixing tank.
[0007] A dilution liquid adjustable valve is connected to the water outlet branch pipe, and a fertilizer solution discharge valve is connected to the fertilizer feeding branch pipe.
[0008] By adopting the above technical solution, when the pump body is working, one end of the water inlet pipe far from the pump body is connected to a water source, and one end of the water outlet pipe far from the pump body is used for irrigation. When starting to pump water, the mixing box is in an empty state. First, the fertilizer and water discharge valve needs to be closed. Water enters the mixing box through the water outlet branch pipe. At the same time, the feeding mechanism puts fertilizer into the mixing box. The water and fertilizer entering the mixing box maintain a specific ratio, so that the concentration of the fertilizer and water in the mixing box is kept within a certain range.
