A pump and a battery box are installed on the side wall of the mixing tank. A liquid guide pipe is snapped into the output end of the pump, and multiple sets of connecting pipes are fixedly passed through the side wall of the liquid guide pipe. A drip pipe is installed at one end of each set of connecting pipes, and multiple sets of connecting rings and multiple sets of mounting rings are fixedly sleeved on the side wall of each set of drip pipes.

[0004] The above-mentioned solution can accelerate the dissolution of organic fertilizer granules through the separator pipe, improving the practicality of the integrated water and fertilizer device for vegetable greenhouses. However, the above-mentioned solution is inconvenient to automatically adjust the nozzle angle during implementation, resulting in a small water and fertilizer spraying range during irrigation, which reduces the centralized supply efficiency of the greenhouse. Therefore, we provide a centralized water and fertilizer supply device for greenhouse vegetables to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution for a centralized water and fertilizer supply device for greenhouse vegetables.

[0027] Please see Figure 1 , Figure 2 and Figure 3 The system includes a mixing tank 1 and a crossbeam 2. The mixing tank 1 is used to mix the water and fertilizer, making the mixture more uniform and improving the irrigation effect. The crossbeam 2 is installed on the top of the greenhouse and is used to fix and support the irrigation device. The structural components shown in the attached drawings are illustrative examples. The specific implementation should be adapted and optimized based on the functional requirements, assembly conditions, and process limitations of the actual application scenario, including the structural parameters, dimensions, and connection methods.

[0028] Please see Figure 1 and Figure 2 A water pump 3 is fixedly installed on the outside of the mixing tank 1. The input end of the water pump 3 is fixedly connected to the mixing tank 1 through a water pipe. The inner bottom wall of the mixing tank 1 has a certain inclined surface, which facilitates the water pump 3 to pump the mixed solution inside the mixing tank 1 to the water supply pipe 4 through the water pipe. The water pump 3 and the servo motor 10 are existing technologies, and will not be described in detail in this application.

[0029] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The output end of the water pump 3 is fixedly connected to the water pipe 4. The outer surface of the mixing tank 1 is fixedly connected to the fixing frame 7. The water pipe 4 passes through the fixing frame 7 and is fixedly connected to the fixing frame 7. The water pipe 4 provides water and fertilizer solution for the irrigation operation of the irrigation mechanism 5. The fixing frame 7 is used to fix and support the water pipe 4, so that the water pipe 4 remains stable during use and avoids external factors such as collision or vibration from affecting the stability of the device.

[0030] Please refer to it again. Figure 1 and Figure 2 Inside the mixing tank 1, a rotating rod 8 is rotatably connected. A set of stirring rods 9 are fixedly connected to the outer surface of the rotating rod 8. A servo motor 10 is fixedly installed on the top surface of the mixing tank 1. The top of the rotating rod 8 is fixedly connected to the output shaft of the servo motor 10. When the servo motor 10 is started, it can drive the rotating rod 8 to rotate inside the mixing tank 1. The rotation of the rotating rod 8 can drive the stirring rods 9 to stir the water-fertilizer mixture solution, thereby making the irrigation solution more evenly mixed and effectively improving the growth effect of vegetables inside the greenhouse.

[0031] The top surface of the mixing tank 1 is fixedly connected to the feed cylinder 11, and the outer surface of the mixing tank 1 is fixedly installed with the water inlet pipe 12. The feed cylinder 11 facilitates the planting personnel to pour fertilizer into the mixing tank 1, and the water inlet pipe 12 serves to add irrigation water into the mixing tank 1. The inside of the water inlet pipe 12 is fixedly installed with a solenoid valve, which facilitates the staff to control the opening and closing of the water inlet pipe 12. The solenoid valve is existing technology and will not be described in detail in this application.

[0032] A mounting base 13 is fixedly connected to the bottom surface of the mixing tank 1. The mounting base 13 is used to increase the contact area between the mixing tank 1 and the bottom surface, thereby effectively improving the stability of the mixing tank 1 in use. The outer surface of the mounting base 13 has a set of evenly distributed fixing plates. The fixing plates have fixing holes, which make it convenient for users to fix the mounting base 13 with existing structures such as bolts.

[0033] Please see Figure 1 and Figure 3 A set of fixing rings 6 are fixedly connected to the bottom surface of the crossbeam 2 by bolts. The fixing rings 6 are adapted to the water supply pipe 4. The fixing rings 6 can fix and limit the water supply pipe 4, so that the water supply pipe 4 can be stably installed on the bottom surface of the crossbeam 2, improving the stability of the device.

[0034] Please see Figure 1 , Figure 3 and Figure 4Below the crossbeam 2, there is a set of irrigation mechanism 5. Irrigation mechanism 5 includes irrigation pipe 501. One end of irrigation pipe 501 is threadedly connected to installation pipe 505. Installation pipe 505 is fixedly connected to water supply pipe 4. When water pump 3 pumps the mixed water and fertilizer solution in mixing tank 1 into water supply pipe 4, the solution inside water supply pipe 4 will enter irrigation pipe 501 through installation pipe 505, so that sprinkler head 504 can carry out sprinkler irrigation operation.

[0035] One end of the irrigation pipe 501 is rotatably connected to a rotating platform 502. A sealing gasket 506 is movably connected inside the rotating platform 502. The sealing gasket 506 is located between the irrigation pipe 501 and the rotating platform 502. The solution enters the rotating platform 502 through the irrigation pipe 501. The sealing gasket 506 is made of rubber and can seal the irrigation pipe 501 and the rotating platform 502 to prevent the solution from flowing out through the gap between them.

[0036] A set of spray pipes 503 is fixedly connected inside the rotating platform 502. After the solution in the rotating platform 502 enters the spray pipes 503, it will be sprayed onto the vegetables below through the nozzles 504. By setting up multiple sets of spray pipes 503 and nozzles 504, the irrigation area of ​​the device can be effectively increased, and the efficiency of centralized water and fertilizer supply in the greenhouse can be improved.

[0037] Each nozzle 503 is fixedly connected to a set of nozzles 504. The distribution position and installation angle of each set of nozzles 504 are different. When the nozzles 504 spray the solution, the different angles of the nozzles 504 will generate a thrust on the nozzle 503, thereby driving the rotating platform 502 to rotate at the end of the irrigation pipe 501, further increasing the effective irrigation range of the nozzles 504, and making the solution more evenly distributed during the irrigation process, thus improving the irrigation effect of the device.

[0038] Working principle: When using this device, the operator first pours the fertilizer into the mixing tank 1 through the feed cylinder 11, and adds water to the mixing tank 1 through the water inlet pipe 12. Then, the servo motor 10 is started, which drives the rotating rod 8 to rotate. The rotating rod 8 drives the stirring rod 9 to rotate, thereby stirring the mixed solution. After stirring for a certain period of time, the operator starts the water pump 3. The water pump 3 pumps the water-fertilizer mixture in the mixing tank 1 to the water delivery pipe 4. The solution in the water delivery pipe 4 enters the irrigation pipe 501 along the installation pipe 505, and is sprayed out through the rotating table 502 and the spray pipe 503 via the nozzle 504. When the nozzle 504 sprays the solution, due to its position and angle, it will use the reaction force of the water to push the rotating table 502 to rotate on the irrigation pipe 501 at the same time, thereby increasing the irrigation range of the device.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
