[0024] like Figure 1-Figure 4 As shown, the water-fertilizer integrated sprinkler irrigation equipment of the embodiment of the present application may include a box body 1, a sprinkler irrigation mechanism 2, a premixing component 3 and a pumping component 4.

[0025] The sprinkler mechanism 2 is arranged on the box body 1 , and the sprinkler mechanism 2 is communicated with the box body 1 .

[0026] The premixing assembly 3 may include a premixing tank 31 and a mixing mechanism 32 .

[0027] The premixing box 31 is arranged in the box body 1 , and the mixing mechanism 32 is arranged in the premixing box 31 .

[0028] The pumping assembly 4 may include a pumping pipe 41 , a piston 42 , a rotating rod 43 , a connecting pipe 44 , a driving mechanism 45 , a first one-way solenoid valve 46 , a second one-way solenoid valve 47 and a gas distribution mechanism 48 .

[0029] Among them, the extraction pipe 41 is fixedly arranged at the bottom of the premixing box 31, and the top of one side of the extraction pipe 41 is connected to the sprinkler mechanism 2 through the connecting pipe 44, the first one-way solenoid valve 46 and the second one-way solenoid valve 47 are respectively arranged at the bottom of the premixing box 31 and the connecting pipe 44, and the first one-way solenoid valve 46 is respectively connected to the interior of the premixing box 31 and the interior of the extraction pipe 41, the rotating rod 43 is rotatably arranged at the bottom of the premixing box 31, and the rotating rod 43 is slidably connected to the premixing box 31 up and down, the piston 42 is arranged on the rotating rod 43, and the piston 42 is rotatably connected to the rotating rod 43, the piston 42 is arranged in the extraction pipe 41, and the mixing mechanism 32 is axially slidably connected to the rotating rod 43, the gas distribution mechanism 48 is arranged in the box body 1, and the gas distribution mechanism 48 is respectively connected to the outside of the box body 1 and the interior of the extraction pipe 41, the driving mechanism 45 is connected to the rotating rod 43, and the driving mechanism 45 is used to drive the rotating rod 43 to rotate and simultaneously drive the rotating rod 43 to reciprocate up and down.

[0030] It should be noted that the box body 1 and the premixing box 31 described in this embodiment are respectively connected with a water inlet pipe (not specifically marked in the figure) and a drain pipe (not specifically marked in the figure), and valves (not specifically marked in the figure) are respectively provided on the two water inlet pipes and the two drain pipes.

[0031] As a possible situation, the box body 1 described in this embodiment can be arranged on a cargo vehicle (not shown in the figure), so that the box body 1 can be moved by the cargo vehicle to realize mobile sprinkler irrigation of crops.

[0032] Specifically, when it is necessary to fertilize crops with sprinkler irrigation, the relevant personnel first inject clean water into the box body 1 and the premixing box 31 through the two water inlet pipes, and add a certain amount of fertilizer into the premixing box 31. Then the relevant personnel start the sprinkler irrigation mechanism 2 and the driving mechanism 45 respectively, and the sprinkler irrigation mechanism 2 extracts the clean water in the box body 1 to sprinkle the crops. At the same time, the driving mechanism 45 drives the rotating rod 43 to rotate, so as to drive the mixing mechanism 32 to premix the clean water and fertilizer in the premixing box 31, and the driving mechanism 45 also drives the rotating rod 43 to reciprocate up and down to drive the piston 4 2 reciprocates up and down. When the piston 42 moves downward, the fertilizer mixture in the premixing box 31 is extracted through the first one-way solenoid valve 46, and when the piston 42 moves upward, the fertilizer mixture is injected into the sprinkler irrigation mechanism 2 through the connecting pipe 44 and the second one-way solenoid valve 47. The fertilizer mixture entering the sprinkler irrigation mechanism 2 is mixed with clean water and sprayed out to achieve fertilization operation on crops. After being mixed by the mixing mechanism 32, the fertilizer can effectively avoid precipitation and accumulation of the fertilizer, and the fertilizer mixture can be more evenly mixed with clean water, thereby effectively improving the uniformity of fertilizer spraying.

[0033] When it is necessary to apply water to the crops separately, the relevant personnel close the first one-way solenoid valve 46 and the second one-way solenoid valve 47 respectively, and start the air distribution mechanism 48 to replenish and exhaust the air in the extraction pipe 41 to prevent the piston 42 from continuing to extract the fertilizer mixture, thereby realizing separate control of fertilization and watering, with a wider range of applications, and the separate operations of watering and fertilization can be achieved through a sprinkler irrigation mechanism 2, which effectively simplifies the equipment structure and reduces production costs.

[0034] It should be noted that before the fertilization operation, the relevant personnel can close the first one-way solenoid valve 46 and the second one-way solenoid valve 47 respectively, and start the gas distribution mechanism 48 to replenish and exhaust air in the injection pipe 41, so as to drive the mixing mechanism 32 through the driving mechanism 45 to pre-mix the fertilizer mixture for a period of time, thereby further improving the uniformity of the mixing of the fertilizer and clean water.

[0035] In one embodiment of the present application, Figure 1-Figure 4 As shown, the driving mechanism 45 may include a motor 451 , a driving rod 452 , a bevel gear 453 and a spiral blade 454 .

[0036] Among them, the motor 451 is fixedly installed on the box body 1, one end of the driving rod 452 is coaxially connected to the output shaft of the motor 451, and the other end of the driving rod 452 extends into the extraction tube 41, the bevel gear 453 is sleeved on the end of the driving rod 452 away from the motor 451, the spiral leaf 454 is sleeved on the rotating rod 43, and the bottom end face of the spiral leaf 454 is provided with a gear groove (not shown in the figure) that meshes with the bevel gear 453.

[0037] Specifically, the relevant personnel start the motor 451 to drive the driving rod 452 to rotate, and the driving rod 452 drives the bevel gear 453 to rotate. When the bevel gear 453 rotates, it drives the spiral blade 454 and the rotating rod 43 to rotate through the gear groove, and drives the rotating rod 43 to move up and down under the action of the spiral blade 454, so that the motor 451 periodically rotates forward and reverse, driving the rotating rod 43 to reciprocate up and down while rotating.

[0038] In one embodiment of the present application, Figure 1-Figure 4 As shown, the mixing mechanism 32 may include a sleeve 321 and a plurality of stirring blades 322 .

[0039] The sleeve 321 is axially slidably sleeved on the rotating rod 43 , and one end of the sleeve 321 is rotatably connected to the top of the inner wall of the premixing box 31 , and a plurality of stirring blades 322 are fixedly connected to the outer peripheral surface of the sleeve 321 .

[0041] Specifically, the rotating rod 43 rotates and drives the sleeve 321 to rotate, and then drives the plurality of stirring blades 322 to rotate through the sleeve 321, thereby achieving the purpose of mixing the fertilizer and the clean water.

[0045] Specifically, in the fertilizing state, the air supply solenoid valve 482 is in a closed state, and the first one-way solenoid valve 46 and the second one-way solenoid valve 47 are in an open state, so that the piston 42 extracts the fertilizer mixture through the first one-way solenoid valve 46 .

[0046] When the equipment is in the water application state, the air supply solenoid valve 482 is opened, and the first one-way solenoid valve 46 and the second one-way solenoid valve 47 are in the closed state to prevent the piston 42 from continuing to extract the fertilizer mixture, and to perform air supply and exhaust operations in the injection pipe 41 through the air supply pipe 481 and the air supply solenoid valve 482.
