[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a nozzle device for irrigation of an agricultural drone, comprising a flow pipe 1 for temporarily storing water, a water inlet 2 for supplying irrigation water into the flow pipe 1 of the device is arranged at the top of the flow pipe 1, a nozzle 3 for spraying irrigation water outward is fixedly connected to the bottom of the flow pipe 1, and a regulating component for controlling the flow of irrigation water is arranged on the inner wall of the flow pipe 1;

[0032] The circulation pipe 1 includes a pipe body 11 and an inner pipe 12 for containing irrigation water. The space between the inner wall of the pipe body 11 and the outer wall of the inner pipe 12 is a water storage area, which can be used to temporarily store irrigation water. The inner pipe 12 is fixedly connected to the inner wall of the circulation pipe 1. The outer wall of the inner pipe 12 is provided with an inlet trough 13 for irrigation water to enter the water storage area. The outer wall of the inner pipe 12 is designed with a water outlet trough 14 near the bottom for irrigation water to leave the water storage area. When the inlet trough 13 and the outlet trough 14 are not blocked, the irrigation water can enter the water storage area through the water inlet 2 and the inlet trough 13, and leave the water storage area through the outlet trough 14 to enter the nozzle 3.

[0033] Reference Figure 1 - Figure 3 The nozzle 3 includes a shell 31 for receiving irrigation water. The top of the shell 31 is fixedly connected to the bottom of the pipe body 11. The irrigation water discharged from the water outlet trough 14 will directly enter the interior of the shell 31. The bottom of the shell 31 is fixedly connected to a diverter plate 32 for dividing the entire water flow into small water columns. The inner wall of the shell 31 is provided with an anti-blocking groove 33 for relieving blockage when the diverter plate 32 is blocked. The bottom of the shell 31 is provided with an auxiliary water outlet 34 for use with the anti-blocking groove 33. The anti-blocking groove 33 and the auxiliary water outlet 34 are connected to each other. The center line of the anti-blocking groove 33 is vertically upward. When the diverter plate 32 is blocked and the water output is reduced, the excess irrigation water will accumulate in the shell 31. As the water level rises, when the water level is higher than the top of the anti-blocking groove 33, the irrigation water will enter the auxiliary water outlet 34 through the anti-blocking groove 33 and be discharged outward through the auxiliary water outlet 34.

[0034] Reference Figure 1 and Figure 2 The regulating component includes a slider 41 for controlling water inlet and water outlet. The slider 41 is slidably connected to the inner wall of the inner tube 12. A sealing gasket 42 for blocking the water inlet 2 is fixedly connected to the top of the slider 41. When the water flow inside the water inlet 2 is strong, the water flow will squeeze the sealing gasket 42 downward to force the slider 41 to move downward, so that the water inlet 2 remains unobstructed. The outer diameter of the sealing gasket 42 is the same as the inner diameter of the water inlet 2. When the sealing gasket 42 leaves the bottom end of the water inlet 2, the irrigation water can enter the water storage area through the water inlet trough 13. The outer wall of the slider 41 is provided with a water outlet 45 for the irrigation water to leave the water storage area. When the water outlet 45 is connected to the water outlet trough 14, the irrigation water in the water storage area can pass through the water outlet 45 and The water outlet trough 14 leaves the water storage area and enters the nozzle 3. The inner wall of the inner tube 12 is fixedly connected with a support plate 44 for supporting the sealing spring 43. The support plate 44 penetrates and slides on the inner wall of the slider 41. When the slider 41 moves up and down, it will also be restricted by the support plate 44, so that it can only move vertically up and down but cannot rotate. The top of the support plate 44 is fixedly connected with a sealing spring 43 for driving the slider 41 to move upward and reset. The top of the sealing spring 43 is fixedly connected to the bottom of the slider 41. When the impulse of the water flow flowing in the water inlet 2 continues to decrease, the sealing spring 43 will push the slider 41 upward to make it move upward, and the slider 41 will drive the sealing pad 42 to move upward to block the water inlet 2 again.

[0035] Working principle: During use, when irrigation is required, the irrigation component can be controlled to drive the irrigation water into the interior of the water inlet 2. After the water flows into the interior of the water inlet 2, the water flows downwardly squeeze the sealing gasket 42 to force it to drive the slider 41 to move downward, and the sealing gasket 42 itself will also be driven to move until the water inlet groove 13 is no longer blocked. When the slider 41 moves downward, it will squeeze the sealing spring 43. At the same time, when the slider 41 moves downward, it will also drive the water outlet 45 to move downward so that the water outlet 45 and the water outlet groove 14 are connected to each other. Then the water flow can enter the water storage area through the water inlet groove 13, and leave the water storage area through the water outlet groove 14 and the water outlet 45 to enter the interior of the nozzle 3.

[0036] When the water flow is cut off, the sealing spring 43 will push the slider 41 upward to make it move upward. The upward movement of the slider 41 will directly drive the sealing gasket 42 to move upward to block the bottom end of the water inlet 2. At the same time, the slider 41 will also drive the water outlet 45 to move upward, and the water outlet 45 and the water outlet trough 14 will no longer be connected. At this time, the irrigation water remaining in the tube body 11 will be stored in the water storage area and cannot enter the interior of the sprinkler head 3.

[0037] 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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
