The water outlet of the fertilizing barrel 21 is detachably connected to the Venturi fertilizer applicator 43 through a connecting pipeline 5. A spare pipeline 6 is also configured on the fertilizing barrel 21. The water inlet end of the spare pipeline 6 is located inside the fertilizing barrel 21, and the water outlet end of the spare pipeline 6 is detachably connected to the Venturi fertilizer applicator 43. Control valves are provided on the first branch pipeline 31, the connecting pipeline 5 and the main fertilizer suction pipeline 41, and the control valves are electrically connected to the control cabinet 1.

[0029] As Figure 1 and Figure 2 shown, the fertilizing barrel 21 has a hollow internal structure and is used to load a mixture of fertilizer and water. A fertilizer adding port is provided at the top of the fertilizing barrel 21, and fertilizer is added into the fertilizing barrel 21 through the fertilizer adding port. An upper cover 22 is covered on the fertilizer adding port, and the upper cover 22 is threadedly connected to the fertilizing barrel 21. The liquid inlet of the fertilizing barrel 21 is connected to the main water pipe 3 through a first branch pipeline 31. A first valve 32 is provided on the first branch pipeline 31, and the connection and disconnection between the first branch pipeline 31 and the main water pipe 3 are controlled through the first valve 32 to facilitate the addition of water to the fertilizing barrel 21.

[0030] As Figure 1 and Figure 4As shown, a stirring shaft 23 is rotatably arranged in the fertilizer application barrel 21. A stirring motor 24 is fixedly arranged at the top of the fertilizer application barrel 21. The output shaft of the stirring motor 24 vertically penetrates through the top of the fertilizer application barrel 21 and extends into its interior. The output shaft of the stirring motor 24 is connected to the stirring shaft 23 through a coupling (not shown in the figure). The setting of the coupling facilitates the installation and disassembly of the stirring shaft 23. The stirring shaft 23 is provided with a first stirring assembly 231 and a second stirring assembly 232. The first stirring assembly 231 and the second stirring assembly 232 are arranged along the axial direction of the stirring shaft 23. The first stirring assembly 231 and the second stirring assembly 232 have the same structure. The size of the first stirring assembly 231 is larger than that of the second stirring assembly 232. The first stirring assembly 231 is arranged close to the bottom of the fertilizer application barrel 21. The first stirring assembly 231 includes a fixed sleeve 2311. The fixed sleeve 2311 is coaxially sleeved outside the stirring shaft 23. Three connecting plates 2312 are evenly distributed along the circumferential direction of the outer periphery of the fixed sleeve 2311. The three connecting plates 2312 are inclined. The number of the connecting plates 2312 can also be two, four or more. The specific number is determined according to design or use requirements and is not limited here. Stirring blades 2313 are arranged on the connecting plates 2312. The stirring blades 2313 are of a trapezoidal structure. The width of the stirring blades 2313 gradually decreases from the outer periphery of the fixed sleeve 2311 outward to reduce the resistance of water during the stirring process. Under the combined stirring action of the first stirring assembly 231 and the second stirring assembly 232, the water and fertilizer in the fertilizer application barrel 21 have a higher stirring efficiency and a better stirring effect, and the water and fertilizer can be fully mixed.

[0031] A fertilizer suction pump 54 is also provided on the connecting pipeline 5. The connecting pipeline 5 includes a first connecting pipeline 51, a second connecting pipeline 52, and a third connecting pipeline 53 that are connected in sequence along the water flow direction. The inlet end of the first connecting pipeline 51 is communicated with the liquid outlet of the fertilizer application barrel 21, the outlet end of the first connecting pipeline 51 is communicated with the inlet end of the fertilizer suction pump 54, the outlet end of the fertilizer suction pump 54 is communicated with the inlet end of the second connecting pipeline 52. The fertilizer suction pump 54 is electrically connected to the control cabinet 1, and the start and stop of the fertilizer suction pump 54 are controlled through the control cabinet 1. The outlet end of the second connecting pipeline 52 is communicated with the inlet end of the third connecting pipeline 53 through a union joint 55, and the outlet end of the third connecting pipeline 53 is connected to the Venturi fertilizer applicator 43. Among them, a filter 56 is provided on the second connecting pipeline 52, and the filter 56 is used to filter impurities in the fertilizer solution. A second valve 44 is provided on the main fertilizer suction pipeline 41, a third valve 57 is provided on the first connecting pipeline 51, and a fourth valve 58 is provided on the third connecting pipeline 53. The first valve 32, the second valve 44, the third valve 57, and the fourth valve 58 are all solenoid valves and are all electrically connected to the control cabinet 1, and the opening and closing of each valve are controlled through the control cabinet 1. Among them, the model of the solenoid valve is not limited, and it can be opened manually and automatically. The control cabinet 1 can select a mature product available on the market and can be simply set according to specific use. Its specific structure and working principle will not be elaborated here.

[0032] As Figure 3 shown, a spare pipeline 6 is also configured on the fertilizer application barrel 21. When the control cabinet 1 fails and it cannot control the start of the fertilizer suction pump 54 or the fertilizer suction pump 54 cannot start by itself, the mixed fertilizer solution in the fertilizer application barrel 21 cannot be transported to the main water pipe 3. At this time, the spare pipeline 6 is used to connect it to the Venturi fertilizer applicator 43, and the fertilizer solution in the fertilizer application barrel 21 is sucked into the main water pipe 3. When connecting the spare pipeline 6, first remove the upper cover 22 from the fertilizer application barrel 21, put the water inlet end of the spare pipeline 6 into the fertilizer application barrel 21 and locate it at the lower part inside the fertilizer application barrel 21. The water outlet end of the spare pipeline 6 is detachably connected to the Venturi fertilizer applicator 43. The Venturi fertilizer applicator 43 is an existing Venturi tube, and its specific structure and working principle will not be elaborated here. In this embodiment, the union joint 55 is rotated and loosened to disconnect the second connecting pipeline 52 from the third connecting pipeline 53, and then the water outlet end of the spare pipeline 6 is connected to the union joint 55, realizing the connection between the fertilizer application barrel 21 and the Venturi fertilizer applicator 43. A filter screen (not shown in the figure) is fixedly provided at the water inlet end of the spare pipeline 6, effectively preventing impurities in the fertilizer application barrel 21 from being sucked into the Venturi fertilizer applicator 43 and avoiding blockage of each pipeline.

[0033] During daily irrigation, the intelligent water-fertilizer integrated machine of the utility model opens the second valve 44 completely, and the water in the water source system flows into the main water pipe 3 through a water pump (not shown in the figure), and is transported to the irrigation equipment of the irrigation network through the main water pipe 3 to irrigate the crops on a daily basis. When irrigation and fertilization are required at the same time, fertilizer is added into the fertilizer barrel 21, the first valve 32 is opened, water is poured into the fertilizer barrel 21 to a predetermined height, and then the first valve 32 is closed, and the stirring motor 24 is started. The output shaft of the stirring motor 24 rotates to drive the stirring shaft 23 connected thereto to rotate synchronously, and the water and fertilizer are stirred and fully mixed by the stirring blades 2313 in the first stirring component 231 and the second stirring component 232. Then, the stirring motor 24 is closed, the third valve 57 and the fourth valve 58 are opened, and the fertilizer suction pump 54 is started. The fertilizer liquid in the fertilizer barrel 21 flows through the first connecting pipeline 51, the second connecting pipeline 52, the third connecting pipeline 53 and the Venturi fertilizer applicator 43 in sequence, and then flows into the main water pipe 3. The fertilizer liquid is mixed with the water in the main water pipe 3 again and flows into the irrigation pipe network and various irrigation equipment, so as to finally realize crop irrigation and fertilization at the same time.

[0034] When the control cabinet 1 fails and cannot control the fertilizer suction pump 54 to start or the fertilizer suction pump 54 cannot start automatically, such as Figure 3 As shown, the upper cover 22 is removed from the fertilizer barrel 21, and the water inlet end of the spare pipeline 6 with the filter screen is placed in the lower part of the fertilizer barrel 21, and the flexible joint 55 is turned and loosened to disconnect the second connecting pipeline 52 and the third connecting pipeline 53. Then, the water outlet end of the spare pipeline 6 is connected to the flexible joint 55, so as to realize the connection between the fertilizer barrel 21 and the Venturi fertilizer applicator 43. The second valve 44 is closed, and part of the water in the main water pipe 3 flows into the fertilizer absorption branch pipeline 42. When the water flows through the Venturi fertilizer applicator 43, due to the pressure difference, the fertilizer liquid in the fertilizer barrel 21 flows through the spare pipeline 6 and the third connecting pipeline 53, and is sucked into the fertilizer absorption branch pipeline 42 through the Venturi fertilizer applicator 43 and then merged into the main water pipe 3. The fertilizer liquid is mixed with the water in the main water pipe 3 again and flows into the irrigation pipe network and various irrigation equipment together, so as to finally realize fertilization while irrigating crops. The setting of the spare pipeline 6 has a backup function, which improves the working stability of the intelligent water-fertilizer integrated machine.

[0035] Although the present invention discloses a preferred specific embodiment to achieve the above-mentioned purpose, it is not intended to limit the structural features of the present invention. Any person skilled in the art should know that under the technical spirit of the present invention, any easily conceivable changes or modifications are possible and are all covered by the scope of the patent application of the present invention.
