Technical Field

[0001] This utility model relates to the field of farmland irrigation technology, specifically to an integrated water and fertilizer irrigation device. Background Technology

[0002] With the development of technology, farmland irrigation is becoming increasingly intelligent. Intelligent management can better monitor plant growth and water and fertilizer application. Integrated water and fertilizer management involves applying fertilizer solution during irrigation, thus combining irrigation and fertilization. This method results in more uniform fertilization, and crops absorb nutrients while absorbing water, thereby improving water and fertilizer utilization.

[0003] For example, the Chinese authorized patent with announcement number CN221653170U is entitled "An Integrated Water and Fertilizer Irrigation Device," which includes: a mobile base and a storage tank, the storage tank being mounted on the mobile base; a mixer and a fixed-point irrigator, the mixer being mounted on the storage tank and the mobile base; the fixed-point irrigator being mounted on the mobile base; the mixer including a top cover, a stirring motor, a stirring frame, and a water pump; the top cover being mounted on the storage tank; the stirring motor being mounted on the top cover with its output shaft rotatably penetrating through the top cover; the stirring frame being rotatably mounted on the top cover and connected to the output shaft of the stirring motor; and the water pump being mounted on the mobile base with its inlet connected to the storage tank.

[0004] However, in the process of modern agricultural development, the outer shell mold of the intelligent water and fertilizer integrated head unit plays a crucial role. The outer shell mold needs to have good sealing performance to prevent water and fertilizer leakage and protect the environment. It also needs to have a certain strength and stability to withstand various external forces and ensure the normal operation of the head unit. At the same time, the current water and fertilizer integrated head unit equipment lacks convenience in operation and cannot meet the diverse needs of the current use environment. Therefore, it does not meet the current requirements. In response, we propose an integrated water and fertilizer irrigation device. Utility Model Content

The bottom of the fertilizer mixing tank 45 is equipped with a water intake pipe 49. A second electric control valve 25 is installed on the water intake pipe 49. The end of the water intake pipe 49 extends out of the fiberglass shell 15. The infusion pipeline is equipped with a centrifugal filter 6 and a mesh filter 14. A drain pipe is installed at the bottom of the mesh filter 14. A third electric control valve 27 is installed on the drain pipe. The bottom of the centrifugal filter 6 is connected to a sand collection tank 5. The sand collection tank 5 is equipped with a sand discharge pipe 9. A first electric control valve 11 is installed on the sand discharge pipe 9. The water pump 1, the first electric control valve 11, the second electric control valve 25, the third electric control valve 27, the fourth electric control valve 39, the flow meter 2, and the fertilizer pump 19 are all connected to the central processing controller.

[0034] The infusion pipeline includes a main pipeline, the inlet pipe of which is connected to a water pump 1, which is connected to a water well, i.e., a water source well pump, used to pump water from the well to the main pipeline. The other end of the main pipeline has a drain pipe 13 extending out of the fiberglass shell 15 for connection to the irrigation network. The fertilizer mixing tank 45 includes a fertilizer inlet 47, a stirring motor 46, and a liquid level detection device. The water inlet is connected to the liquid delivery pipeline through a first pipe 37. A fourth solenoid valve 39 is installed on the first pipe 37. In actual use, when the water level in the fertilizer mixing tank reaches the set value of the liquid level detection device, the central operating controller automatically closes the fourth solenoid valve 39 on the water inlet pipeline to prevent overflow. A certain amount of fertilizer is weighed and added into the fertilizer mixing tank 45 through the fertilizer inlet 47. The central operating controller is connected to the flow meter 2 and the stirring motor 46. The addition of water to the fertilizer mixing tank 45 is controlled by the fourth solenoid valve 39, and the amount of water added is obtained through the flow meter 2.

The automatic fertilizer adding device can weigh the fertilizer under the control of the central operating controller and add it into the fertilizer mixing tank, thereby automatically preparing the fertilizer solution.

[0035] Example 2

[0036] Please see Figure 1-6The fertilizer mixing tank 45 is connected to a fertilizer pump 19. The output end of the fertilizer pump 19 is connected to the infusion pipeline, and the inlet end of the fertilizer pump 19 is connected to the infusion pipeline through a second pipe 35. A venturi tube 31 is connected to the middle area of ​​the second pipe 35 and is connected to the inside of the fertilizer mixing tank 45. The outlet end of the fertilizer pump 19 is connected to the infusion pipeline through a third pipe 36. In this way, when the fertilizer pump 19 is working, it can draw water from the infusion pipeline and draw fertilizer solution from the fertilizer mixing tank through the venturi tube during the drawing process, thereby adding fertilizer solution to the infusion pipeline and outputting it along with the irrigation water. A water intake pipe 49 is provided at the bottom of the fertilizer mixing tank 45, and a fourth electrically controlled valve 39 is provided on the drain pipe of the fertilizer mixing tank. The end of the water intake pipe 49 extends out of the fiberglass shell 15.

[0037] Specifically, a water intake pipe 49 is installed at the bottom of the fertilizer mixing tank 45, and a second electrically controlled valve 25 is installed on the water intake pipe 49. The second electrically controlled valve 25 is connected to the central processing controller. During normal operation, the second electrically controlled valve 25 is in the closed state. When the temperature is low and there is a risk of freezing, an antifreeze command can be sent via a mobile phone. At this time, the fourth electrically controlled valve 25 is opened to drain the residual water or fertilizer solution in the fertilizer mixing tank, thereby reducing the risk of the fertilizer mixing tank freezing and cracking, and achieving the antifreeze effect.

[0038] Specifically, a water intake pipe 49 is installed at the bottom of the fertilizer mixing tank 45, and a second electrically controlled valve 25 is installed on the water intake pipe 49. The second electrically controlled valve 25 is connected to the central processing controller. When the drone is spraying pesticides, the pesticide can be directly taken through the water intake pipe 49 at the bottom of the fertilizer mixing tank 45. The second electrically controlled valve 25 is opened according to the instructions sent by the mobile phone to take the pesticide. This simplifies the pesticide mixing process for drones and eliminates the need to carry fertilizer mixing tools. After the fertilization or pesticide mixing work is completed, the second electrically controlled valve 25 is also opened to drain the fertilizer mixing tank. The infusion pipeline is equipped with a centrifugal filter 6 and a mesh filter 14.

[0039] Specifically, this setup allows for the filtration of sand and gravel in the water by the centrifugal filter 6, followed by further filtration by the mesh filter, thereby removing impurities from the water. The inlet 47 of the fertilizer mixing tank is connected to the main pipeline, ensuring the cleanliness of the water entering the fertilizer mixing tank and reducing the risk of blockage in the subsequent drip irrigation network. The bottom of the mesh filter 14 is equipped with a drain pipe, and a third electrically controlled valve 27 is installed on the drain pipe.

[0040] Specifically, the third solenoid valve 27 is connected to the central control unit and can discharge the wastewater in the mesh filter 14 after it has been working for a period of time, achieving automatic cleaning. It can also be controlled to open and discharge water to prevent freezing due to water inside the mesh filter in winter. The bottom of the centrifugal filter 6 is connected to a sand collection tank 5, which is equipped with a sand discharge pipe 9, and a first solenoid valve 11 is installed on the sand discharge pipe 9.

[0041] Specifically, the sand collection tank 5 can collect the sand and gravel filtered by the centrifugal filter 6. The first solenoid valve 11 is connected to the central control controller, which can control the first solenoid valve 11 to open for a certain period of time after the centrifugal filter has been working for a certain period of time, so as to discharge the sand and gravel in the sand collection tank and achieve the purpose of automatic cleaning.

[0043] The water pump 1, the first electrically controlled valve 11, the second electrically controlled valve 25, the third electrically controlled valve 27, the fourth electrically controlled valve 39, the flow meter 2, and the fertilizer pump 19 are all connected to the central processing controller.

[0044] Furthermore, the base 3 has a rectangular structure, with the fertilizer mixing tank 45 located at one corner of the base. The centrifugal filter 6, sand collection tank 5, and hand-cranked mesh filter 9 are located on the other side of the fertilizer mixing tank 45. The main pipeline is arranged in an L-shape, effectively utilizing the space on both sides of the fertilizer mixing tank. The electrical control box 59 is located on the water and fertilizer pipeline. This arrangement effectively utilizes space, minimizing the overall size of the farmland's main structure.

[0045] Furthermore, an operation panel 66 is provided on the outer casing. The operation panel 66 is connected to the central arithmetic controller, so that the various components can be controlled using the operation panel.
