[0002] Corn is one of my country's crops, with high nutritional value and is an excellent food crop. When planting corn, it needs to be fertilized and irrigated, especially during the dry season. If the soil is dry, granular fertilizer cannot be applied to the roots of the corn. Usually, irrigation and fertilization need to be carried out together so that water can carry the fertilizer to the roots of the corn.

[0003] Existing corn irrigation systems have a continuous flow of water, which makes it difficult to mix the water and fertilizer evenly, thus hindering the fertilizer's effectiveness and resulting in waste. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an irrigation device for corn planting, and the technical solution adopted is as follows:

[0005] An irrigation device for corn planting includes a dosing tank, which is divided into two parts by a partition. A stirring motor is installed above each dosing tank, and a stirring rod is connected to the lower end of each stirring motor. A water level sensor is installed in each of the two dosing tanks. An electrical box is located on one side of the dosing tank, and a water pump is installed inside the electrical box. The inlet of the water pump is connected to a main water outlet pipe, the other end of which is connected to the bottom of one of the dosing tanks. A branch water outlet pipe, connected to the bottom of the other dosing tank, is connected to the main water outlet pipe. A solenoid valve is installed in both the main water outlet pipe and the branch water outlet pipe.

[0006] A main water inlet pipe is installed on the side opposite to the electrical box in the medicine preparation box, which is connected to part of the medicine preparation box. A branch water inlet pipe is connected to the main water inlet pipe, which is connected to the other part of the medicine preparation box. A solenoid valve is installed in both the main water inlet pipe and the branch water inlet pipe.

[0007] Furthermore, a plug is provided above the medicine dispensing box and on both sides of the partition to seal the opening on the upper surface of the medicine dispensing box. The plug can be opened to add fertilizer into the medicine dispensing box.

[0008] Furthermore, an observation window is provided in the medicine dispensing box on each side of the electrical box, allowing observation of the interior of both parts of the medicine dispensing box.

[0009] Furthermore, a pressure relief pipe is installed on each side of the mixing tank to release the gas generated by the fertilizer inside the mixing tank and prevent excessive pressure inside the mixing tank.

[0011] Furthermore, a controller is installed at one end inside the electrical box. This controller is connected to the stirring motor, water level sensor, inlet solenoid valve, outlet solenoid valve, and water pump. The controller can be a PLC controller.

[0012] Furthermore, a cover plate is bolted to one side of the electrical box. If any electrical components inside the electrical box are damaged during operation, the cover plate on one side of the electrical box can be opened for inspection and repair.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention, through the design of two-part dispensing tanks, allows for alternating water injection, pesticide addition, and drainage. This enables the water pump to continuously deliver water mixed with fertilizer into the soil, ensuring thorough mixing and maximizing the fertilizer's effectiveness. The continuous supply of water after fertilizer mixing further improves the efficiency of corn irrigation. Furthermore, by connecting to the irrigation pipe in the soil via a connecting pipe, water is directly delivered to the corn roots, saving water resources.

[0015] The two parts of the medicine dispensing tank of this utility model are the same size, and the water level can be kept constant each time water is added under the action of the water level sensor. Therefore, the amount of fertilizer added into the medicine dispensing tank each time is also the same. Thus, no additional proportions are needed when adding fertilizer, making it more convenient to use. Attached Figure Description

Detailed Implementation

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0023] As attached Figure 1-4 As shown.

[0024] An irrigation device for corn planting includes a mixing tank 1, which is divided into two parts by a partition. The two parts of the mixing tank 1 have the same function. A stirring motor 2 is provided above each part of the mixing tank 1. A stirring rod 21 is connected to the lower end of each stirring motor 2. A plug 11 is provided above the mixing tank 1 and on both sides of the partition to seal the opening on the upper surface of the mixing tank 1. Fertilizer can be added into the mixing tank 1 by opening the plug 11, and it can be fully mixed with the water in the mixing tank 1 by the stirring rod 21.

[0025] An electrical box 4 is provided on one side of the medicine preparation box 1. An observation window 12 is provided on both sides of the electrical box 4 in the medicine preparation box 1, which can observe the interior of the two parts of the medicine preparation box 1. A water level sensor 14 is also provided in each of the two parts of the medicine preparation box 1.

[0026] A water inlet main pipe 3 is installed on the side opposite to the electrical box 4 in the medicine preparation box 1, which is connected to a part of the medicine preparation box 1. A water inlet branch pipe 31 connected to another part of the medicine preparation box 1 is connected in the water inlet main pipe 3. A water inlet solenoid valve 32 is provided in both the water inlet main pipe 3 and the water inlet branch pipe 31. The other end of the water inlet main pipe 3 is connected to a pump body. Water is injected into different parts of the medicine preparation box 1 in a circulating manner by opening the water inlet solenoid valve 32 in the water inlet main pipe 3 and the water inlet branch pipe 31.

[0027] A water pump 7 is installed inside the electrical box 4. The inlet of the water pump 7 is connected to the main outlet pipe 6. The other end of the main outlet pipe 6 is connected to the bottom of a portion of the medicine tank 1. A branch outlet pipe 61 connected to the bottom of another medicine tank 1 is connected to the main outlet pipe 6. A solenoid valve 62 is installed in the main outlet pipe 6 and the branch outlet pipe 61 respectively. A connecting pipe 71 is connected to the outlet of the water pump 7. The connecting pipe 71 is connected to the irrigation pipe in the land. When the water pump 7 is started, the water containing fertilizer in the two medicine tanks 1 can be circulated and transported to the land through the opening of the solenoid valve 62, and then used to irrigate the corn through the irrigation pipe.

[0028] A controller 5 is installed at one end inside the electrical box 4. The controller 5 is connected to the stirring motor 2, the water level sensor 14, the inlet solenoid valve 32, the outlet solenoid valve 62, and the water pump 7. The working process of this device is as follows: the inlet solenoid valve 32 and the outlet solenoid valve 62 connected to the same part of the dosing tank 1 are opened alternately. That is, after a part of the dosing tank 1 is filled with water, the inlet solenoid valve 32 connected to that part of the dosing tank 1 is closed. Then, by opening the plug 11 above that area, fertilizer can be added into the dosing tank 1. Since the size of the dosing tank 1 is constant, the water level can also be kept constant each time water is added under the action of the water level sensor 14. Therefore, fertilizer can be added directly in the same proportion, making the fertilizer:water ratio more convenient.

[0029] After adding fertilizer, the controller 5 turns on the stirring motor 2 at that position to mix the fertilizer in the partial dosing tank 1. When the water level sensor 14 in the other dosing tank 1 detects that the water level has dropped to the bottom, the two outlet solenoid valves 62 can be switched on and off to continue to deliver the prepared water to the soil through the water pump 7. At this time, the inlet solenoid valve 32 connected to the dosing tank 1 in the drainage area opens to inject water into the area. After the water is filled, the above operation is repeated.

[0030] Thus, by setting up two parts of the dosing tank 1, the water pump 7 can continuously deliver water containing fertilizer into the soil. To facilitate operation by staff, in addition to adding fertilizer, the starting of the other parts, such as the inlet solenoid valve 32, the outlet solenoid valve 62, the stirring motor 2, and the water pump 7, can be automatically performed by programming instructions from the controller 5. The water level sensor 14 is used as an information acquisition device. The controller 5 can be a PLC controller, which is more convenient for programming in this type of work.

[0031] In addition to the above methods, the inlet solenoid valve 32, the outlet solenoid valve 62, the stirring motor 2, and the water pump 7 can also be manually controlled by the buttons on the controller 5.

[0032] If any electrical components inside the electrical box 4 are damaged during operation, the cover plate 41 on one side of the electrical box 4 can be opened for inspection.

[0033] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
