Description

Technical Field

[0001] This utility model relates to the technical field of integrated water and fertilizer machines, specifically to an integrated water and fertilizer machine. Background Technology

[0002] In agricultural planting, the use of integrated water and fertilizer machines combines irrigation and fertilization. Soluble fertilizers are mixed into fertilizer solution through a pressure system (or natural terrain drop) and then transported to the crop root zone in a timely and quantitative manner along with irrigation water through a pipeline system. This is a method of agricultural planting management.

[0003] Chinese patent document CN222090159U discloses a water and fertilizer integrated machine. Through the combined action of multiple structures including a dispersing device, a stirring device, and a filtration structure, it not only improves the dissolution speed and utilization rate of fertilizer, but also greatly reduces the possibility of irrigation nozzle clogging.

[0004] In the above scheme, after the fertilizer is added from the inlet, it needs to be crushed by a dispersing device before entering the water and fertilizer tank for mixing by a stirring device. Then, a water pump transports the mixed water and fertilizer to the filter box, where it is further processed by the internal filtration structure. Finally, another water pump transports the filtered water and fertilizer solution to the field for irrigation. This process involves multiple processing units, resulting in a relatively complex overall structure. This not only increases the equipment manufacturing cost and floor space but also brings inconvenience to daily inspection and maintenance. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing an integrated water and fertilizer machine.

[0006] The technical solution of this utility model is as follows: A water and fertilizer integrated machine includes a mixing box, crossbars, a connecting shell, and a limiting component. The connecting shell is installed in the middle of the inner side of the mixing box. The middle of the connecting shell is provided with a filter component for filtering fertilizer in use. The limiting component is located inside the filter component and connected to the mixing box. The middle of the limiting component is provided with an agitator component connected to the mixing box and used to mix fertilizer and water inside the filter component in use. There are multiple crossbars, all of which are located inside the limiting component and arranged towards the center of the limiting component.

[0007] Preferably, the connecting shell includes a housing and a tube. The housing is installed in the middle of the inner side of the mixing chamber, and the tube is disposed on the side of the housing and communicates with the housing, with its end extending to the bottom of the inner side of the mixing chamber.

[0008] Preferably, the filtration assembly includes a mesh basket and a filter bag. The mesh basket is installed inside the housing and has water passage holes on its surface. The filter bag is disposed inside the mesh basket and wrapped around the outside of the limiting assembly.

[0009] Preferably, the inner bottom of the shell has a convex ring, and the top of the basket has a flange ring. When the shell and the basket are installed together, the flange ring of the basket overlaps the convex ring of the shell.

[0010] Preferably, the limiting component includes a cover plate, a connecting frame, and a pressure ring. The cover plate covers the top of the mixing chamber, the connecting frame is installed at the bottom center of the cover plate and located inside the filter bag, and the pressure ring is sleeved on the outside of the connecting frame and located above the mesh basket and connected to the end of the filter bag.

[0011] Preferably, the gap between the outer side of the connecting frame and the inner side of the mesh basket is arranged to match the size of the filter bag.

[0012] Preferably, the agitation assembly includes a rotating shaft, a motor, and stirring blades. The rotating shaft is rotatably mounted in the middle of the cover plate and extends to the inner side of the connecting frame at its bottom end.

[0014] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: This invention uses an agitator to stir the water-fertilizer mixture within a filter assembly. The resulting centrifugal force forces the mixture through the filter assembly into a mixing tank.

[0016] Example 1, as Figure 1-3As shown, this utility model proposes a water and fertilizer integrated machine, including a mixing tank 1, a crossbar 14, a connecting shell, and a limiting component. The connecting shell is installed in the middle of the inner side of the mixing tank 1, and has an extension end on its side extending to the bottom of the inner side of the mixing tank 1. This extension allows water inside the mixing tank 1 to flow into the connecting shell under negative pressure during use. A filter assembly for filtering fertilizer is located in the middle of the connecting shell during use. The limiting component is located inside the filter assembly and connected to the mixing tank 1. When connected to the mixing tank 1, it limits the position of the filter assembly, thereby fixing the filter assembly to the connecting shell via the limiting component. The limiting assembly has a stirring component in the middle that is connected to the mixing box 1 and mixes fertilizer and water inside the filter assembly in use. There are multiple crossbars 14, which are arranged inside the limiting assembly and facing the center of the limiting assembly. When the stirring component mixes water and fertilizer inside the filter bag 10, the stirring component drives the water to rotate inside the filter bag 10 and pushes it towards the filter bag 10. The fertilizer will rotate with the water. During the rotation, the crossbars 14 act as fixed obstacles and collide with and shear the moving fertilizer particles, quickly breaking large fertilizer particles into small particles and initiating initial dissolution.

[0017] In this embodiment, the filter assembly is placed inside the connecting shell, and the agitator is inserted into the filter assembly using a limiting component. The limiting component is connected to the mixing tank 1 by bolts. Under the tightening action of the bolts, the limiting component moves downward, pressing and fixing the filter assembly inside the connecting shell. Then, the agitator is activated to strongly stir the water and fertilizer inside the filter assembly, forming obvious eddies and turbulence inside. This pushes the water-fertilizer mixture to diffuse outwards and, under pressure, passes through the filter assembly and enters the mixing tank 1. During this process, a negative pressure area is formed at the top of the filter assembly, including the inside of the connecting shell, causing the connecting shell to draw water from the inside of the mixing tank 1 into the filter assembly. Water is added to the filter assembly, creating a circulating flow within the filter assembly and mixing tank 1. Simultaneously, fertilizer particles within the filter assembly are carried by the water flow, impacting and violently striking the crossbar 14. This effectively breaks down large pieces of fertilizer or large particles into finer particles. At the same time, the crossbar 14 also exerts a shearing effect on the water flow. When the water flow is forced to bypass the crossbar, a high-speed shearing zone is formed at the edge of the crossbar 14, further tearing and pulverizing fertilizer particles and softened colloidal substances. This structure is simple, easy to inspect and maintain, and not only achieves thorough mixing and efficient filtration of fertilizer and water, improving mixing uniformity, but also effectively prevents the water-fertilizer solution from clogging the irrigation nozzles.

[0018] Example 2, as Figure 2-3As shown, the present invention proposes a water and fertilizer integrated machine. Compared with embodiment one, the difference in this embodiment is that the connecting shell includes a shell 7 and a pipe 8. The shell 7 is installed in the middle of the inner side of the mixing tank 1. The top center of the mixing tank 1 has a mounting hole. The inner dimension of the top of the shell 7 is the same as the size of the mounting hole. Multiple pipes 8 connected to the shell 7 are installed on the side of the shell 7. One end of the pipe 8 extends to the bottom of the inner side of the mixing tank 1. When the stirring component pushes the water and fertilizer mixture inside the filter component to the inner side of the mixing tank 1, the low pressure generated inside the filter component can be directly transported to the inner side of the mixing tank 1 through the pipe 8, avoiding the need to replenish water to the inner side only through the seepage effect of the filter component, thus improving the water replenishment efficiency.

[0019] In this embodiment, the filter assembly is supported and limited by the housing 7. During use, a sealed cavity communicating with the tube 8 is formed on the inner side of the housing 7 in cooperation with the limiting component. When the stirring component mixes water and fertilizer inside the limiting component, the stirring component rotates at high speed inside the limiting component, pushing the water and fertilizer to the surroundings. Under pressure, the water and fertilizer pass through the filter assembly and enter the main body of the mixing tank 1. At the same time, due to the sealing of the connecting shell and the high-speed rotation of the stirring component, it is equivalent to a centrifugal pump. When the stirring component continuously "pumps" the fluid out of the filter assembly, a stable and continuous negative pressure (low pressure zone) is formed inside the entire limiting component (including the inner side of the housing 7 and the upper end of the tube 8). The negative pressure actively and forcibly draws liquid from the bottom of the mixing tank 1 through the tube 8 extending to the bottom of the inner side of the mixing tank 1 to replenish and replace the water inside the filter assembly. This creates a circulating flow between the water inside the filter assembly and the water inside the mixing tank 1, thereby fully mixing the fertilizer and water and performing the filtration process on the fertilizer.

[0020] Example 3, as Figure 2-3 As shown, the present invention proposes a water and fertilizer integrated machine. Compared with the first embodiment, the difference in this embodiment is that the filter component includes a mesh basket 9 and a filter bag 10. The mesh basket 9 is installed inside the housing 7 and has water passage holes on its surface. The filter bag 10, which is wrapped around the outside of the limiting component, is installed inside the mesh basket 9.

[0021] In an optional embodiment, the inner bottom of the housing 7 has a protruding ring, and the top of the basket 9 has a flanged ring. When the housing 7 and the basket 9 are installed together, the flanged ring of the basket 9 overlaps the protruding ring of the housing 7, and the size of the basket 9 is adapted to the size of the housing 7. This is used to support and limit the basket 9 during use. A sealing gasket can be provided between the housing 7 and the basket 9 for sealing connection, which is not shown in the figure.

[0022] In this embodiment, by placing the filter bag 10 inside the basket 9 and allowing the basket 9 to carry the filter bag 10 to the inside of the housing 7, the housing 7 supports the basket 9. After the limiting component is installed, the limiting component presses and limits the end of the filter bag 10 at the top of the basket 9. Thus, the basket 9 and the filter bag 10 are fixed by pressure inside the housing 7, allowing the housing 7 to hold the fertilizer while filtering it, preventing large-particle fertilizer from being insoluble in water and being pumped to the irrigation nozzle to block the nozzle.

[0023] Example 4, as Figure 1-3 As shown, the present invention proposes a water and fertilizer integrated machine. Compared with the first embodiment, the difference in this embodiment is that the limiting component includes a cover plate 2, a connecting frame 11, and a pressure ring 13. The cover plate 2 covers the top of the mixing box 1 and is fixedly connected to the mixing box 1 by bolts, so that the cover plate 2 can be disassembled, thereby allowing the filter bag 10 to be cleaned and replaced. The connecting frame 11 is installed in the middle of the bottom end of the cover plate 2 and is located inside the filter bag 10. The pressure ring 13 is sleeved on the outside of the connecting frame 11 and is located above the mesh basket 9 and connected to the end of the filter bag 10.

[0024] In an optional embodiment, the gap between the outer side of the connecting frame 11 and the inner side of the mesh basket 9 is adapted to the size of the filter bag 10, so as to fit and connect the inner wall and outer wall of the filter bag 10 to the connecting frame 11 and the mesh basket 9 respectively in use, so that the installation of the connecting frame 11 is more stable.

[0025] In this embodiment, the cover plate 2 is installed on the top of the connecting frame 11 and the pressure ring 13 is installed on the outside of the connecting frame 11. When the cover plate 2 drives the connecting frame 11 to be inserted into the inside of the filter bag 10, the connecting frame 11 restricts the filter bag 10 to prevent it from shrinking inward. The connecting frame 11 drives the pressure ring 13 to be placed above the ends of the mesh basket 9 and the filter bag 10. The cover plate 2 and the mixing box 1 are bolted together. The connecting frame 11 drives the pressure ring 13 to press and fix the ends of the mesh basket 9 and the filter bag 10, so that the mesh basket 9 and the filter bag 10 are fixed inside the housing 7, making it easier to inspect and maintain. The cover plate 2 supports the stirring component, so that the stirring component rotates in the middle of the cover plate 2 to stir and mix the water and fertilizer.

[0026] Example 5, such as Figure 1-3As shown, the present invention proposes a water and fertilizer integrated machine. Compared with embodiment one, the difference in this embodiment is that the stirring component includes a rotating shaft 3, a motor 4, and a stirring blade 12. The rotating shaft 3 is rotatably installed in the middle of the cover plate 2 and its bottom end extends to the inner side of the connecting frame 11. The number of stirring blades 12 is at least one. The stirring blades 12 are installed on the outside of the rotating shaft 3 and located on the inner side of the connecting frame 11. The motor 4 is installed at the top of the mixing box 1 and connected to the top of the rotating shaft 3. The motor 4 is connected to the rotating shaft 3 through a chain drive structure, or the motor 4 can be installed above the cover plate 2 and directly connected to the rotating shaft 3 through a coupling.

[0027] In this embodiment, the motor 4 drives the rotating shaft 3 to rotate in the middle of the cover plate 2, thereby driving the stirring blade 12 to stir the water and fertilizer inside the filter bag 10. This causes the water and fertilizer to form eddies and turbulence through the stirring blade 12, pushing the water and fertilizer mixture to spread in all directions. Under pressure, the mixture passes through the filter assembly and enters the mixing box 1. The fertilizer particles in the filter assembly are carried by the water flow, impacting and violently striking the motor crossbar 14, thereby effectively breaking down large pieces of fertilizer or large particles into finer particles.

[0028] Example 6, as Figure 1 As shown, the water and fertilizer integrated machine proposed in this utility model, compared with the first embodiment, further includes a cover 5 and a feed pipe 6. The feed pipe 6 is installed on one side of the top of the cover plate 2 and its end extends to the inside of the connecting frame 11. The cover 5 is installed on the top of the cover 5 and is sealed to the cover 5. The cover 5 can be detachably connected to the feed pipe 6, so that when the cover 5 is connected to the feed pipe 6, the top of the feed pipe 6 is sealed and the cover 5 can be easily removed.

[0029] In this embodiment, by separating the cap 5 from the feed pipe 6, fertilizer can be conveyed to the inside of the filter bag 10 through the feed pipe 6. After the cap 5 is connected to the feed pipe 6, the cap 5 seals the top of the feed pipe 6, so that the top of the shell 7 is in a closed state. When the stirring blade 12 mixes water and fertilizer and conveys it through the filter bag 10 to the inside of the mixing box 1, it can generate negative pressure on the inside of the shell 7. Then, through the cooperation of the negative pressure and the pipe body 8, the water inside the mixing box 1 is conveyed to the filter bag 10, so that the water inside the filter bag 10 and the water inside the mixing box 1 form a circulating flow state, making the water and fertilizer mix more evenly.

[0030] In this invention, by separating the cap 5 from the feed pipe 6, fertilizer can be conveyed to the inside of the filter bag 10 through the feed pipe 6. After the cap 5 is connected to the feed pipe 6, the cap 5 seals the top of the feed pipe 6, so that the top of the shell 7 is in a closed state. The motor 4 is started to drive the rotating shaft 3 to rotate in the middle of the cover plate 2, which in turn drives the stirring blade 12 to rotate at a high height inside the connecting frame 11, so that it strongly stirs the water and fertilizer, forming obvious vortices and turbulence inside, pushing the water-fertilizer mixture to spread to the surroundings, and under pressure, it passes through the filter bag 10 and enters the mixing box 1. During this process, a negative pressure area is formed inside the connecting shell, so that the connecting shell, through the cooperation of the negative pressure and the pipe body 8, mixes the fertilizer. Water is drawn from the inside of the mixing tank 1 into the filter bag 10 to replenish its water supply, creating a circulating flow between the filter bag 10 and the mixing tank 1. Simultaneously, fertilizer particles inside the filter bag 10 are carried by the water flow, impacting and violently striking the crossbar 14. This effectively breaks down large pieces of fertilizer or large particles into finer particles. The crossbar 14 also exerts a shearing effect on the water flow. When the water flow is forced to bypass the crossbar, a high-speed shearing zone is formed at the edge of the crossbar 14, further tearing and crushing fertilizer particles and softened colloidal substances. This structure is simple, easy to inspect and maintain, and not only achieves thorough mixing and efficient filtration of fertilizer and water, improving mixing uniformity, but also effectively prevents the water-fertilizer solution from clogging the irrigation nozzles.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
