Water and fertilizer are delivered to the roots of plants on demand through the irrigation system. This technology has significant advantages: it can save water resources and fertilizers and reduce environmental pollution; by accurately controlling the water-fertilizer ratio, it can significantly increase the growth rate and yield of crops; it reduces the labor intensity of manual fertilization and irrigation, and improves the efficiency and sustainability of agricultural production. Water-fertilizer integration technology is an important direction for the development of modern agriculture, and provides an effective way to achieve agricultural production and efficiency increase and sustainable resource utilization. The real-time online water-fertilizer system refers to the process of mixing water and fertilizer in the pipeline and then applying it directly to the crops to achieve the purpose of immediate application. The online water-fertilizer system has the advantages of small size and high fertilization efficiency.

[0040] In response to the above problems, an embodiment of the present application provides a water-fertilizer mixer that combines water-dynamic vortex mixing and electric spiral mixing, which can solve or alleviate the problems of low mixing efficiency and large mixer size existing in the water-fertilizer mixer in the online water-fertilizer system.

[0041] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0042] See also Figure 1 , 2 4. The water-fertilizer mixer integrating hydrodynamic vortex mixing and electric spiral mixing comprises a hydrodynamic mixing mechanism 1, a connecting piece 2, and a controllable electric mixing mechanism 3. The hydrodynamic mixing mechanism 1 and the controllable electric mixing mechanism 3 are connected via the connecting piece 2.

[0043] The hydrodynamic mixing mechanism 1 includes a diverter top cover 11, a diverter core 12, a mother liquid dispersion device 13, a fixed ring 14, and a hydrodynamic mixing chamber shell 15. The upper part of the inner cavity of the hydrodynamic mixing chamber shell 15 is a feed chamber, and the lower part is a first water-fertilizer mixing chamber. A fixed ring 14 is installed in the middle of the hydrodynamic mixing chamber shell 15. The mother liquid dispersion device 13 is installed in the feed chamber through the inner ring of the fixed ring 14, and its mother liquid inlet pipe 131 passes through the side wall of the hydrodynamic mixing chamber shell 15. Through holes are evenly opened on the fixed ring 14. The lower end of the diverter core 12 is correspondingly installed in the through hole and is connected to the first water-fertilizer mixing chamber. The top of the hydrodynamic mixing chamber shell 15 is sealed with a diverter top cover 11, and an irrigation water inlet is opened on the diverter top cover 11. The upper end of the diverter core 12 is connected to the irrigation water inlet.

[0044] During operation, water enters through the irrigation water inlet on the diverter top cover 11, and then is diverted to the first water-fertilizer mixing chamber through the diverter core 12; mother liquor enters through the mother liquor inlet pipe 131, and then is dispersed to the first water-fertilizer mixing chamber through the mother liquor dispersion device 13 for mixing; and then enters the controllable electric mixing mechanism 3 through the connector 2 for mixing; the whole process utilizes the principle of fluid mechanics combined with the active drive motor to complete efficient mixing of water and fertilizer, providing support conditions for higher detection and fertilizer mixing accuracy for the online water-fertilizer integrated system, and can solve or alleviate the problems of low mixing efficiency and large mixer volume in the water-fertilizer mixer in the online water-fertilizer system.

[0045] In some embodiments, see Figure 5The diverter core 12 includes a diverter plate 121, the diameter of which matches the inner diameter of the hydrodynamic mixing chamber housing 15, and three diverter core partitions 122 are evenly arranged on the upper side of the diverter plate 121 along the circumferential direction. Three diverter holes 123 are evenly opened on the diverter plate 121, and the diverter holes 123 are arranged crosswise with the diverter core partitions 122, and the diverter holes 123 are located in the middle of two adjacent diverter core partitions 122 near the outer edge of the diverter plate 121, and a diverter channel 124 is correspondingly arranged on the lower side of the diverter hole 123, and the diverter channel 124 is connected to the through hole on the fixing ring 14, and correspondingly, there are three through holes on the fixing ring 14.

[0046] During operation, each diversion core partition 122 is 120° apart, arranged radially and connected together. This structure evenly divides the irrigation water into three water flows with equal flow rates. The three diverted water flows into the corresponding conical cavities. The three cavities evenly occupy one-third of the entire conical space. The conical space is separated by the diversion core partition 122, and forms a sealing structure with the diverter top cover 11. The water in the conical cavity flows through the diversion hole 123 and the diversion channel 124 to the first water-fertilizer mixing chamber for mixing. The diversion channel 124 is designed to be flat in order to smoothly generate a vortex water flow when entering the space below, increase the width of the vortex water flow, and improve the stability of the vortex.

[0047] In some embodiments, see Figure 7 A limit groove is vertically provided on the upper inner wall of the hydrodynamic mixing chamber shell 15, and a limit block is correspondingly provided on the fixed ring 14. The limit block is slidably installed in the limit groove. A vortex guide vane 16 is provided at the lower part of the inner cavity of the hydrodynamic mixing chamber shell 15. The vortex guide vane 16 is arranged corresponding to the through hole on the fixed ring 14, and the vortex guide vane 16 is bent from 90° vertically downward to a 30° downward inclination with the horizontal direction.

[0048] During operation, the vortex guide vane 16 bends from 90° vertically downward to a 30° downward inclination with the horizontal direction, and a stable vortex can be formed at this time. The three diversion outlets of the diversion core 12 are installed directly above the corresponding vortex guide vane 16. The three water flows pass through the vortex guide vane 16 to form a stable vortex in the first water-fertilizer mixing chamber. At the same time, the mother liquor after pressurized dispersion is mixed with the vortex water flow and enters the controllable electric mixing mechanism 3 through the bottom through hole.

[0049] In some embodiments, see Figure 6The mother liquid dispersion device 13 also includes a conical shell 132 and a pressurized shell 133. The small end of the conical shell 132 is connected to the mother liquid inlet pipe 131, and the large end is connected to the upper end of the pressurized shell 133. The inner cavity of the pressurized shell 133 is a pressurized dispersion chamber. Dispersion holes 134 are opened on the bottom disk of the pressurized shell 133. The dispersion holes 134 are arranged equidistantly in a circular array with the center of the disk as the center of the circle. The diameter of the dispersion holes 134 increases gradually from the center of the bottom of the pressurized dispersion chamber along the radial direction outward.

[0050] When working, the conical shell 132 is installed between the mother liquid inlet pipe 131 and the pressurized dispersion chamber, which plays a role in increasing the stability of the structure and extending the service life. There are 40 dispersion holes 134 distributed at the bottom of the pressurized dispersion chamber. The distribution pattern of these 40 dispersion holes 134 is: with the center of the disk as the center of the circle, they are arranged equidistantly from the outside of the disk in a circular array. There are 8 dispersion holes 134 distributed on each circumference. The adjacent dispersion holes 134 on the same circumference are evenly distributed at 45°. The diameter of the dispersion holes 134 gradually increases radially outward from the center of the bottom of the pressurized dispersion chamber. According to calculations, when the sum of the areas of all the dispersion holes 134 is approximately equal to one-half of the cross-sectional area of ​​the mother liquid inlet, it can be ensured that the pressurized dispersion chamber has sufficient pressure and maintains a certain flow rate, and at the same time, it will not cause a large pressure loss that makes it difficult for the mother liquid to flow out. The size of each circle of dispersion holes 134 is calculated according to the laws of pressure and fluid dynamics. In this way, the flow rate of each dispersion hole 134 can be kept consistent. At this time, the mother liquid can also maintain a uniform flow rate when flowing out from different dispersion holes 134.

[0051] In some embodiments, a mounting edge is provided at the connection between the conical shell 132 and the pressurized shell 133, and the mother liquid dispersion device 13 is connected to the inner ring of the fixing ring 14 through the mounting edge.

[0052] During operation, this design enables the mother liquid dispersion device 13 to be stably installed just above the first water-fertilizer mixing chamber.

[0053] In some embodiments, see Figure 8 , 9 The controllable electric mixing mechanism 3 includes an electric mixing chamber shell 31, a spiral mixing core 32, a mixer bottom component 33, and a driving motor 34. The inner cavity of the electric mixing chamber shell 31 is a second water-fertilizer mixing chamber. The bottom of the electric mixing chamber shell 31 is sealed with a mixer bottom component 33, and a fertilizer liquid outlet pipe 331 is arranged on the mixer bottom component 33. The spiral mixing core 32 is arranged in the second water-fertilizer mixing chamber, and its bottom end passes through the mixer bottom component 33 and is connected to the driving motor 34; the spiral mixing core 32 is provided with a three-layer spiral structure, and the upper and lower surfaces of the mixing core are provided with equally spaced obstruction blocks 321, and the obstruction blocks 321 on the upper and lower surfaces of the same layer of the spiral structure are arranged alternately.

[0054] During operation, the water and fertilizer rotate counterclockwise from the first water-fertilizer mixing chamber to flow into the second water-fertilizer mixing chamber, and the driving motor 34 drives the spiral mixing core 32 to rotate clockwise. When the water and fertilizer enter the second water-fertilizer mixing chamber, they will swirl counterclockwise downward along the spiral mixing core 32. The spiral mixing core 32 has a three-layer spiral structure. The upper and lower surfaces of the spiral mixing core 32 have obstruction blocks 321 arranged at equal intervals. The obstruction blocks 321 are alternately arranged on the upper and lower surfaces of the same layer of channels. When the water and fertilizer flow downward along the spiral mixing core 32, they will impact the obstruction blocks 321 on the upper and lower surfaces back and forth, causing the water and fertilizer liquid to mix with each other. In addition, controlling the speed of the driving motor 34 can control the degree of water and fertilizer impact during the mixing process, which can adapt to more application occasions. Different speeds are designed for different water and fertilizer ratios to be mixed, which can effectively improve the mixing degree and efficiency of the water and fertilizer to achieve the expected mixing effect.

[0055] In some embodiments, the bottom of the hydrodynamic mixing chamber housing 15 and the top of the electric mixing chamber housing 31 are both conical structures, and the upper and lower surfaces of the connecting piece 2 are correspondingly provided with recessed conical grooves, and the two recessed conical grooves are connected. The bottom of the hydrodynamic mixing chamber housing 15 and the top of the electric mixing chamber housing 31 are respectively connected to the recessed conical grooves on the upper and lower surfaces of the connecting piece 2.

[0056] During operation, the three diversion outlets of the diversion core 12 are installed directly above the corresponding vortex guide vanes 16. The three water flows pass through the vortex guide vanes 16 to form a stable vortex on the inverted conical inner wall above the connecting piece 2. At the same time, the mother liquor after pressurized dispersion is mixed with the vortex water flow and enters the second water-fertilizer mixing chamber through the bottom through hole. The design of the conical structure can reduce the mass of the connecting piece, reduce the processing cost and the overall mass of the fertilizer mixer, make it more lightweight, and can play a role in positioning and fixing.

[0057] How this application works:

[0058] The irrigation water inlet of the water-fertilizer mixer is connected to the water delivery pipeline, the mother liquid inlet pipeline 131 is connected to the mother liquid delivery pipeline, and the fertilizer liquid outlet pipe 331 is connected to the fertilizer liquid irrigation pipeline network.

[0059] Irrigation water flows in from the irrigation water inlet through the irrigation delivery pipeline, is evenly divided into three streams of water with equal flow through the separation core 12, flows out through the corresponding diversion channels 124, and enters the first water-fertilizer mixing chamber. Then, the three streams of water with equal flow are guided by the vortex guide plate 16 to form a stable vortex on the inverted cone-shaped inner wall at the bottom of the first water-fertilizer mixing chamber. At the same time, the mother liquid flows into the mother liquid dispersion device 13 from the mother liquid inlet pipe 131 through the mother liquid delivery pipeline, and enters the cylindrical pressurized dispersion chamber. The bottom of the chamber is provided with circular dispersion holes 134. After the mother liquid is pressurized, it is dispersed from these dispersion holes 134. The mixed liquid flows downward into the second water-fertilizer mixing chamber, enters the second water-fertilizer mixing chamber, and rotates along the spiral direction of the spiral mixing core 32. During the flow, the water-fertilizer solution is further mixed in the second water-fertilizer mixing chamber under the obstruction of the obstruction block 321 on the spiral mixing core 32 and the rotation direction of the driving motor 34 opposite to the flow direction of the water-fertilizer solution. Finally, the evenly mixed water-fertilizer solution flows out from the fertilizer liquid outlet pipe 331, enters the fertilizer liquid irrigation pipe network, and is applied to the crops.

[0060] Three-stage mixing principle:

[0061] Level 1: Through the action of the pressurized dispersion chamber, the squeezed mother liquid is evenly sprinkled in the irrigation water that has formed a vortex. The two are initially mixed due to the impact effect and the principle of molecular diffusion. This is the first-level mixing, among which the uniform distribution lays a good mixing foundation for subsequent mixing.

[0062] Second level: After the vortex guide vane 16 in the hydrodynamic mixing structure guides the solution, the radial rotation direction is opposite to the guiding direction of the spiral mixing core 32 in the controllable electric mixing structure 3, which aggravates the fluid turbulence and makes the water and the mother liquid more evenly mixed. In addition, due to the centrifugal force, the water-fertilizer solution will scatter when it flows out of the first water-fertilizer mixing chamber, which is conducive to the mixing of water and fertilizer.

[0063] Level 3: After the water-fertilizer solution flows into the second water-fertilizer mixing chamber, during the process of flowing downward along the spiral mixing core 32, the driving motor 34 drives the spiral mixing core 32 to rotate in the direction opposite to the flow direction of the water-fertilizer solution. During this process, the water-fertilizer solution is impacted by the obstruction blocks 321 on the upper and lower surfaces of the spiral mixing core 32, forming turbulence, accelerating the movement of fluid molecules, and making the water-fertilizer mixing more uniform.
