[0024] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0025] Please refer to Figure 1-3 As a specific implementation method, the present application provides an intelligent farmland head, which includes a water-fertilizer integrated irrigation module and a central operation controller connected to the water-fertilizer integrated irrigation module, and also includes: a voice control module, which is connected to the central operation controller.

[0026] Specifically, the central operation controller is connected to the control of each unit in the water-fertilizer integrated irrigation module. In the prior art, the central operation controller is connected to the mobile phone APP through wireless communication. For example, the Chinese utility model patent with application number CN202321041645.0 discloses a deep buried infiltration irrigation technology for farmland and its supporting intelligent water-fertilizer integrated management head. The central operation controller is used to control the connection between the intelligent water-fertilizer integrated irrigation head and the water source well pump system, and the intelligent water-fertilizer integrated irrigation head and the water source well pump are controlled by the central operation controller. The central operation controller in this application can be consistent with that in the prior art and is used to control the operation of the water-fertilizer integrated irrigation module. The difference between this application and the prior art is that this application is provided with a voice control module in the water-fertilizer integrated irrigation module. The voice control module is connected to the central operation controller, and the voice recognition module recognizes the user's voice instructions to control the central operation controller to operate the water-fertilizer integrated irrigation module, thereby realizing voice control, thereby further improving the intelligence of the farmland head.

[0027] Further, as a specific embodiment, refer to Figure 2-Figure 6 The water-fertilizer integrated irrigation module includes: a base 1, a shell 50 covering the base 1, and a fertilizer box 39 and a liquid infusion pipeline integrated in the shell 50. The fertilizer box 39 includes a liquid level detection device, a first tube 37 connected to the liquid infusion pipeline, and a fertilizer box drainage pipe 42.

[0028] Specifically, the infusion pipeline includes a main line 5, whose water inlet pipe 19 is connected to a water pump 6. Water pump 6 is connected to a well, i.e., a water source well pump, and is used to pump water from the well into the main line 5. A drainage pipe 22 at the other end of the main line extends out of the housing 50 for connection to the irrigation network. The fertilizer tank 39 includes a fertilizer inlet 47, a stirring motor 72, and a liquid level detection device. A water inlet is provided at the top of the fertilizer tank 39, which is connected to the infusion pipeline via a first pipe 37. A third electrically controlled valve 45 is provided on the first pipe 37. During actual use, when the water level in the fertilizer tank reaches the setting value of the liquid level detection device, the central operation controller automatically closes the third electrically controlled valve 45 on the water inlet pipeline to prevent overflow.

[0029] A certain amount of fertilizer is weighed and added to the fertilizer tank 39 from the fertilizer adding port 47. The central operation controller is connected to the flow meter 29 and the stirring motor 72. Water is added to the fertilizer tank 39 by controlling the third electric control valve 45, and the amount of water added is obtained through the flow meter 29. The fertilizer liquid of a certain concentration is stirred and configured by the stirring motor 72.

[0030] Furthermore, in some embodiments, a device for automatically adding fertilizer (not shown in the figure) can be provided at the fertilizer inlet 47. The automatic fertilizer adding device can weigh the fertilizer under the control of the central operation controller and add it to the fertilizer mixing box, thereby automatically configuring the fertilizer liquid.

[0031] Furthermore, as a specific implementation, the fertilizer distribution box 39 is connected to a fertilizer pump 34, and the output end of the fertilizer pump 34 is connected to the infusion pipeline.

[0032] refer to Figure 3 The liquid inlet end of the fertilizer pump 34 is connected to the infusion pipeline through the second tube 36. The middle area of the second tube 36 is connected to the venturi tube 70. The venturi tube 70 is connected to the inside of the fertilizer distribution box 39. The liquid outlet end of the fertilizer pump 34 is connected to the infusion pipeline through the third tube 35. In this way, the fertilizer pump 34 can suck the water in the infusion pipeline when it is working and suck the fertilizer liquid in the fertilizer distribution box through the venturi tube during the suction process, so that the fertilizer liquid is added to the infusion pipeline and output together with the irrigation water.

[0033] Furthermore, as a preferred embodiment, a fertilizer box drainage pipe 42 is provided at the bottom of the fertilizer box 39 , a fourth electrically controlled valve 44 is provided on the fertilizer box drainage pipe, and an end of the fertilizer box drainage pipe 42 extends out of the housing 50 .

[0034] Specifically, a fertilizer box drain pipe 42 is provided at the bottom of the fertilizer box 39, and a fourth electrically controlled valve 44 is provided on the fertilizer box drain pipe 42. The fourth electrically controlled valve 44 is connected to the central operation controller. During normal operation, the fourth electrically controlled valve 44 is in a closed state. When the temperature is low and there is a risk of freezing, an antifreeze opening instruction can be sent through a voice control module or a mobile phone. At this time, the fourth electrically controlled valve is opened to discharge the remaining water or fertilizer liquid in the fertilizer box, thereby reducing the risk of the fertilizer box being frozen and cracked, and achieving an antifreeze effect.

[0035] Specifically, a fertilizer tank drain pipe 42 is provided at the bottom of the fertilizer tank 39, and a fourth electrically controlled valve 44 is provided on the fertilizer tank drain pipe 42. The fourth electrically controlled valve 44 is connected to the central processing unit. When the drone is spreading pesticides, the pesticides can be directly taken out through the fertilizer tank drain pipe 42 provided at the bottom of the fertilizer tank 39. The fourth electrically controlled valve is opened according to the voice control module or the mobile phone to perform the pesticide dispensing operation. This simplifies the drone's pesticide dispensing process, eliminating the need to carry fertilizer-related tools. When the fertilization or dispensing work is completed, the fourth electrically controlled valve 44 is also controlled to open to discharge the fertilizer tank's wastewater.

[0036] Further, as a preferred embodiment, refer to Figure 3 The infusion pipeline includes a main pipeline 5 and two branch pipelines arranged in parallel in the middle area of the main pipeline. The inlet of the main pipeline 5 is connected to a centrifugal filter 33. One of the two branch pipelines is provided with an automatic backflushing laminated filter 4, and the other is provided with a mesh filter 9. The water inlet is connected to the downstream of the two branch pipelines.

[0037] Specifically, the main pipeline 5 includes two sections, and a first branch pipeline 13 and a second branch pipeline 23 are arranged between the two main pipelines. The first branch pipeline 13 is provided with a mesh filter 9, and the second branch pipeline 23 is provided with an automatic backwash laminated filter 4. The main pipeline 5 at one end connected to the water pump 6 is connected to a centrifugal filter 33, and the water inlet of the fertilizer tank 39 is connected to a section of the main pipeline downstream of the two branch pipelines. Through this arrangement, the gravel in the water can be filtered through the centrifugal filter 33, and then further filtered through the two branch pipelines, thereby filtering out impurities in the water. The water inlet of the fertilizer tank is connected to a section of the main pipeline downstream of the two branch pipelines, which can ensure the cleanliness of the water entering the fertilizer tank and reduce the risk of subsequent drip pipe network being blocked.

[0038] Furthermore, as a preferred embodiment, a sand storage tank 32 is connected to the bottom of the centrifugal filter 33. The sand storage tank 32 is provided with a sand discharge pipe 12, and the sand discharge pipe 12 is provided with a fifth electrically controlled valve 41. Specifically, the sand storage tank 32 can collect the sand filtered by the centrifugal filter 33. The fifth electrically controlled valve 41 is connected to the central processing unit and can be controlled to open for a certain period of time after the centrifugal filter has been operating for a certain period of time to discharge the sand in the sand storage tank, thereby achieving the purpose of automatic cleaning.

[0039] Further, as a specific embodiment, refer to Figure 3 The other end of the centrifugal filter 33 is connected to the pressure relief drain pipe 3, and the other end of the pressure relief drain pipe 3 extends out of the housing 50. The pressure relief drain pipe 3 is provided with a sixth electric control valve 14.

[0040] Specifically, the other end of the centrifugal filter is connected to a pressure relief drain pipe 3. When the water pressure is too high, the central operation controller opens the sixth electronically controlled valve 14 to discharge some water through the pressure relief drain pipe 3 to adjust the water pressure to a normal working range, thereby achieving the function of automatically regulating the water pressure.

[0041] Furthermore, the other end of the centrifugal filter is connected to a pressure relief drain pipe, the other end of the pressure relief drain pipe extends out of the shell, and a sixth electric control valve is provided on the pressure relief drain pipe.

[0042] Furthermore, as a specific implementation, the water pump 6, the first electrically controlled valve 2, the second electrically controlled valve 10, the third electrically controlled valve 45, the fourth electrically controlled valve 44, the fifth electrically controlled valve 41, the sixth electrically controlled valve 14, the flow meter 29 and the fertilizer pump 34 are all connected to the central operation controller.

[0043] Further, refer to Figure 4-Figure 6 As a specific embodiment, the base 1 is a rectangular structure, the fertilizer box 39 is arranged at a corner of the base, the automatic recoil laminated filter 4 and the electric control box 60 are on the same side of the fertilizer box 39; the centrifugal filter 33, the sand storage tank 32, and the mesh filter 9 are arranged on the rear side of the fertilizer box 39, the first branch pipeline and the second branch pipeline are arranged on both sides of the centrifugal filter 33, and the electric control box 60 is located on the upper part of the automatic recoil laminated filter 4.
