[0024] The liquid supply component is used to transport fertilizer liquid to the drip irrigation component, so that the fertilizer liquid fills the drip irrigation component until the fertilizer liquid flows back to the liquid supply component along the second return pipe 23, and the transportation of the fertilizer liquid is stopped. At this time, the amount of fertilizer liquid carried by each drip irrigation component is roughly equal. The air blowing component is used to pressurize the drip irrigation component so that the fertilizer liquid in the drip irrigation component can drip, ensuring that the amount of fertilizer liquid obtained by each plant corresponding to the drip irrigation component is basically equal. The first return pipe 21, the second corrugated pipe 22 and the second return pipe 23 can return excess fertilizer liquid to the liquid supply component during the fertilizer liquid transportation process to avoid waste of fertilizer liquid.

[0025] Wherein, the drip irrigation assembly includes a drip irrigation barrel 2, the top of which is fixedly connected with a liquid inlet pipe 3 and a liquid outlet pipe 4, the bottom of which is fixedly connected with a dropper 5, the top of which is penetrated and fixed with an air cylinder 6, the top of which is fixedly connected with an air supply pipe 15, the top of the inner side of the air cylinder 6 is fixed with a return spring 7, the bottom end of which is fixed with a first piston 8, the first piston 8 is slidably matched with the inner wall of the air cylinder 6, the bottom of the first piston 8 is fixed with a support rod 9, the bottom end of the support rod 9 is fixed with a second piston 11, the second piston 11 is slidably matched with the inner wall of the dropper 5, the outer wall of the support rod 9 is slidably sleeved with a limiting ring 10, the limiting ring 10 is fixedly installed at the bottom of the air cylinder 6, the outer wall of the drip irrigation barrel 2 is fixed with a fixed block 12, the fixed block 12 is slidably inserted with a nail 13, the outer side of the nail 13 is fixedly sleeved with a limiting block 14, and the limiting block 14 is located below the fixed block 12;

[0026] The air cylinder 6 is inflated by the air blowing assembly to pressurize the inside of the air cylinder 6, which can push the first piston 8 downward. The first piston 8 pushes the second piston 11 away from the drip tube 5 with the help of the support rod 9, so that the fertilizer liquid in the drip irrigation assembly can drip. The nails 13 embedded in the soil are used to support and lock the position of the drip irrigation tube 2, so that the drip irrigation assembly corresponds to the plant one by one, thereby better fertilizing the plant with drip irrigation.

[0027] The air blowing assembly includes a support plate 16, on which an air pump 17 is arranged, and the air outlet of the air pump 17 is fixedly connected to an air delivery pipe 18, on which a valve is arranged, and the air delivery pipe 15 is connected to the air delivery pipe 18;

[0028] The air pump 17 is used to inflate the air pipe 18, and the air in the air pipe 18 can enter the interior of the air cylinder 6 along the air supply pipe 15, so that the interior of the air cylinder 6 is pressurized to control the drip irrigation assembly to discharge the fertilizer liquid. After the fertilizer liquid drip irrigation is completed, the valve on the air pipe 18 is opened, and the return spring 7 can pull the first piston 8 to move upward, so that the second piston 11 blocks the dropper 5 again, and the excess air in the air cylinder 6 can be discharged along the air pipe 18.

[0029] Among them, the connecting pipe fitting includes a first corrugated pipe 19, both ends of which are fixedly connected to an infusion tube 20. The first corrugated pipe 19 in the connecting pipe fitting can be expanded and contracted as needed, so that the spacing between each drip irrigation component can be appropriately adjusted according to the position of the plant roots to meet the plant fertilization needs.

[0030] The liquid supply assembly includes a liquid storage cylinder 24 and a water pump 25, both of which are arranged on the base 1, a liquid guide tube 26 is fixedly connected between the liquid inlet of the water pump 25 and the liquid storage cylinder 24, a carrier plate 27 is fixed on the top of the liquid storage cylinder 24, a carrier column 28 is rotatably connected to the bottom of the carrier plate 27 through a bearing, a plurality of stirring rods 29 are fixed on the outer wall of the carrier column 28, a driving motor 30 is arranged on the top of the carrier plate 27, and the carrier column 28 is driven by the driving motor 30;

[0031] The water pump 25 is used to deliver the fertilizer liquid stored in the liquid storage cylinder 24 into the drip irrigation assembly for fertilization. The driving motor 30 can be activated to drive the support column 28 and multiple stirring rods 29 to rotate, so that the multiple stirring rods 29 stir the fertilizer liquid in the liquid storage cylinder 24 to avoid stratification of the fertilizer liquid and affect the balance of fertilization.

[0032] Working principle of this utility model:

[0033] The prepared fertilizer liquid is injected into the liquid storage cylinder 24 for storage, and the driving motor 30 is activated to drive the support column 28 and the multiple stirring rods 29 thereon to rotate, so that the fertilizer liquid in the liquid storage cylinder 24 can be stirred to avoid stratification of the fertilizer liquid. According to the different planting positions of the plant roots, the drip irrigation assembly can be placed above the plant roots, and the nails 13 are hit with a hammer so that the nails 13 are embedded in the soil to support and fix the drip irrigation assembly so that each drip irrigation assembly corresponds to each plant one by one;

[0034] After the preparation work is completed, the water pump 25 is first activated to transport the fertilizer liquid temporarily stored in the liquid storage cylinder 24 to the drip irrigation assembly. After the fertilizer liquid fills each drip irrigation assembly one by one, the excess fertilizer liquid will flow back to the inside of the liquid storage cylinder 24 along the first return pipe 21, the second corrugated pipe 22 and the second return pipe 23. When the staff sees the fertilizer liquid flowing out of the second return pipe 23, the water pump 25 is stopped. The staff then activates the air pump 17 to inflate the air delivery pipe 18, and the air enters the inside of the air cylinder 6 along the air delivery pipe 15. The internal air pressure of the air cylinder 6 is forced to increase, so that the first piston 8 moves downward. The first piston 8 pushes the second piston 11 downward with the help of the support rod 9 and leaves the dropper 5. At this time, the fertilizer liquid in the drip irrigation assembly can drip along the dropper 5 in an orderly manner to fertilize the plants. When the fertilizer liquid in the drip irrigation assembly has all flowed out, the valve on the air pipe 18 is opened, and the return spring 7 pulls the first piston 8 to move upward. The excess air in the air cylinder 6 can be discharged along the air pipe 18, and the second piston 11 blocks the dropper 5 again, waiting for the next drip irrigation operation.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
