[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] An agricultural rainwater harvesting and storage irrigation device, such as Figure 1 As shown. It includes a water storage tank located underground. A first filter screen 3 is horizontally installed on the upper part of the water storage tank. The water storage tank is divided into a mixing tank 1 and a clear water tank 2 by a partition. The mixing tank 1 extends downwards, and its lower part is located below the bottom surface of the clear water tank 2. The bottom surface of the mixing tank 1 slopes downwards towards the sludge suction pump 7 to facilitate sludge sedimentation, while the downward slope of the bottom surface of the mixing tank 1 towards the sludge suction pump 7 facilitates better sludge suction by the sludge suction pump 7. A first suction pump 5 is installed in the middle of the mixing tank 1. The first suction pump is connected to the clear water tank 2 through a first outlet pipe. A second suction pump 6 is installed in the clear water tank 2 and is connected to the outside through a second outlet pipe. A sludge suction pump 7 is installed at the bottom of the mixing tank 1 and is connected to the outside through a sludge discharge pipe. A guide plate 8 inclined towards the mixing tank 1 is installed on the upper part of the clear water tank 2.

[0019] In use, during the rainy season, excess rainwater enters a storage tank. A first filter screen 3 filters out tree branches and vegetation from the rainwater. Because a guide plate 8 is installed above the clear water tank 2, the rainwater, after passing through the first filter screen 3, enters the mixing tank 1 and accumulates there. After the rain stops, the muddy water in the mixing tank settles, and then the first suction pump 5 is activated. The settled clear water, driven by the first suction pump 5, enters the clear water tank 2 through the first outlet pipe, thus accumulating clear water. During the dry season, a second suction pump 6 is activated to extract the clear water, thereby achieving the rational utilization of rainwater resources. The sludge in the mixing tank 1 is extracted by a sludge suction pump 7.

[0020] The upper part of the water storage tank is equipped with an upper annular support plate, and the upper part of the mixing tank 1 is equipped with a lower annular support plate. The first filter screen 3 rests on the upper annular support plate, and the second filter screen 4 rests on the lower annular support plate. The first filter screen 3 is located above the second filter screen 4, and the opening of the second filter screen 4 is smaller than that of the first filter screen 3. The first filter screen 3 and the second filter screen 4 rest on the corresponding upper and lower annular support plates, respectively, so that they can be easily removed for cleaning. The fact that the opening of the second filter screen 4 is smaller than that of the first filter screen 3 ensures that smaller branches can pass through the first filter screen 3 and be blocked by the second filter screen 4, ensuring smooth water intake and better filtration.

[0021] It also includes a feeding box 9, which is set on the ground and connected to the outlet of the second water outlet pipe. A third water outlet pipe 10 is installed inside the feeding box 9, and a feeding port is opened on the top surface of the feeding box 9. Fertilizer or pesticide solution can be added into the feeding box 9, so that pesticides can be injected at the same time during irrigation, thereby saving time and labor.

[0022] The upper part of the water storage tank is equipped with a cover plate 11, which seals the water storage tank. The cover plate 11 is equipped with a handle. The cover plate 11 is installed on the water storage tank and is opened before rain and closed after rain to prevent gaseous animals from entering.

[0023] The use of this application allows rainwater to be stored during the rainy season. At the same time, the first filter screen 3, the second filter screen 4, the mixing tank 1, and the clear water tank 2 are used to filter and settle the water, ensuring that the pumped water is clear water, thus achieving better irrigation for crops.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
