DETAILED DESCRIPTION

[0021] Embodiment 1

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer and more specific, the content of the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the utility model, rather than to limit the utility model. It should also be noted that, for the convenience of description, only the parts related to the utility model are shown in the accompanying drawings, rather than all the contents.

[0023] This embodiment proposes a water-fertilizer integrated irrigation device, such as Figure 1 As shown, it includes a fertilizer storage unit 1, a fertilizer distribution unit 2 and a fertilizer application unit 3, all of which are cylindrical structures of equal size, with a bottom radius of 0.6m, wherein the height of the fertilizer storage unit 1 is 0.3m, the height of the fertilizer distribution unit 2 is 0.4m, and the height of the fertilizer application unit 3 is 0.8m. The fertilizer storage unit 1 is divided into four sector-shaped fertilizer storage areas 101, as shown in FIG. Figure 2 As shown, it is used to store different types of high-concentration liquid fertilizers. A fertilizer outlet 102 is provided at the bottom of each fertilizer storage area 101, a quantitative cup 103 is provided below the fertilizer outlet 102, and a first solenoid valve 104 and a second solenoid valve 105 are provided at the top and bottom of the quantitative cup, respectively. When the first solenoid valve 104 and the second solenoid valve 105 are both in a closed state, the volume of the quantitative cup is 50 mL.

[0024] A water inlet 202 is provided on the upper side of the fertilizer distribution unit 2, and a third solenoid valve 202 is provided at the water inlet 202. A first fixed shaft 203 is provided in the middle of the fertilizer distribution unit 2, and a first stirring mechanism 204 is provided along the first fixed shaft 203. The first stirring mechanism 204 can rotate around the first fixed shaft 203 under the drive of the motor. Figure 3 As shown. A water outlet 205 is provided at the bottom of the fertilizer unit 2, and a fourth solenoid valve 206 is provided at the water outlet 205. A first pressure sensor 207 is also provided at the bottom of the fertilizer unit 2, and the height of the liquid column in the fertilizer unit 2 can be calculated by measuring the real-time pressure. An EC sensor can also be provided in the fertilizer unit 2 to monitor whether the solution in the fertilizer unit 2 is evenly mixed and whether the entire system is operating normally.

[0025] A water outlet 301 is provided at the bottom of the side of the fertilizing unit 3, and a fifth electromagnetic valve 302 is provided at the water outlet 301. A second pressure sensor 303 is provided at the bottom of the fertilizing unit 3 for monitoring the height of the liquid column in the fertilizing unit 3 in real time.

[0026] When in use, first, four kinds of commonly used high-concentration liquid water-soluble fertilizers are respectively added to the four fertilizer storage areas 101 of the fertilizer storage unit 1. When irrigation and fertilization are needed, the user only needs to set the ratio of different fertilizers and the total amount of irrigation to start irrigation and fertilization. The controller opens the third solenoid valve 201 and injects clean water into the fertilizer unit 2. At the same time, by continuously switching the first solenoid valve 104 and the second solenoid valve 105, an integer quantitative cup of different fertilizers is added to the fertilizer unit 2 according to the ratio of different fertilizers set by the user. When the height of the liquid column measured by the first pressure sensor reaches 0.3 meters, the controller closes the third solenoid valve and starts the first stirring mechanism 204 at the same time to fully mix the water and fertilizer. When the conductivity measured by the EC sensor reaches the specified conductivity that allows a certain error, the first stirring mechanism 204 is closed. When the height of the liquid column measured by the second pressure sensor 303 is less than 0.4 meters, the fourth solenoid valve 206 is opened to inject the evenly stirred water and fertilizer solution into the fertilization unit through the drain port 205. When the height of the liquid column measured by the first pressure sensor is 0, the fourth solenoid valve 206 is closed, the fifth solenoid valve 301 is opened, and the water-fertilizer solution is started to be delivered to the sprinkler or drip terminal, and the above-mentioned fertilizer distribution process is repeated at the same time, and the cycle is repeated until the total irrigation amount reaches the user-set value. As long as the fertilizer distribution speed is greater than the total water output speed of the terminal, the continuity of the whole process can be guaranteed. If the control unit has a wireless communication module, parameter setting and remote control can be performed through a mobile phone, so that growers can complete the work of watering and fertilizing at home while enjoying air conditioning and eating watermelon.
