In addition, when the second rotating lever rotates, the stirring blade on the second rotating lever also starts to rotate. The nutrient solution dropped into the water service box 3 can be dissolved in the water of the water service box 3 quickly and uniformly by the agitation of the agitating blade.
Along with the increase of the waste water pumped by the water suction pump, the liquid level of the waste water is gradually increased, and the first water floating block can gradually slide upwards, so that the water outlet pump 5 is opened. Because the moisture total amount in water planting case 1 is relatively fixed, consequently, the accessible sets up the height of conversion piece, when making the suction pump take out the waste water in water planting case 1, the intake pump on switch of conversion piece lower surface is pressed to first water floating block.
Then, the water supply tank 3 is supplied with the nutrient solution by the water supply pump 6, and the nutrient solution is pumped into the hydroponic tank 1. As the moisture drawn into the hydroponic tank 1 increases, the second water float slides upward. When the second water floating block upwards presses the water inlet pump disconnecting switch, the water inlet pump 6 is disconnected to work and does not pump water continuously, and therefore water changing of the device is completed.
By using the system, a worker only needs to calculate the approximate weight of the plant in one period according to experience and then optionally pump the nutrient solution with the number changed in advance and the water in the water supply tank 3. Thereafter, when the water in the hydroponic tank 1 needs to be replaced, the apparatus is automatically replaced.
