Description

However, compared with the development of smart home and smart wearables, the development of smart agriculture is still relatively slow, and there are relatively few related smart fertilization products on the market. In order to ensure agricultural output and normal growth of crops and obtain stable and high yields, crops must be supplied with appropriate fertilizers and sufficient water. People usually fertilize and irrigate farmland manually based on human observation.

[0003] Although traditional artificial fertilization and irrigation methods have been used in agricultural production for a long time, they have many limitations and obvious defects. First, this method relies heavily on manual operation and is labor-intensive. Especially in large-scale farmland management, it often requires a lot of manpower and material resources and is inefficient. Secondly, the supply of fertilizer and water is usually based on the farmers' experience rather than scientific quantitative analysis. This limitation of human experience makes it difficult to accurately control the amount of fertilization and irrigation, and it is easy to over- or under-fertilize, which directly affects the normal growth and final yield of crops.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Please see attached Figure 1 An embodiment of the present invention provides an intelligent agricultural irrigation device based on the Internet of Things technology, including a mixing barrel 1, a water pumping pipe 5 is fixedly connected to the outer wall of the mixing barrel 1, and a water injection component is provided at one end of the water pumping pipe 5 away from the mixing barrel 1, which is used to spray water. A mixing component is provided in the middle of the mixing barrel 1, which is used to stir the water source and fertilizer.

[0035] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 6 The water injection component includes a water pump 6, which is fixedly connected to one end of the water pumping pipe 5, and a water inlet pipe 7 is fixedly connected to the output end of the water pump 6. The end of the water inlet pipe 7 away from the water pump 6 is fixedly connected to a support pipe 8, and a support seat 20 is fixedly connected to the bottom of the support pipe 8. An adjusting component is provided at the bottom of the support seat 20, which is used to adjust the height of the support pipe 8. A three-way pipe 16 is rotatably connected to the top of the support pipe 8, and a connecting pipe 17 is fixedly connected to the middle of the three-way pipe 16. A spray head 18 is fixedly connected to the end of the connecting pipe 17 away from the three-way pipe 16. There are two spray heads 18, and spray holes 19 are opened in the middle of the two spray heads 18. A limiting component is provided in the middle of the three-way pipe 16, which is used to limit the three-way pipe 16 when it rotates. A soil moisture sensor 31, a meteorological sensor 32 and a precipitation sensor 33 are fixedly connected to one side of the water pump 6. The soil moisture sensor 31, the meteorological sensor 32 and the precipitation sensor 33 are all connected to the monitoring system by telecommunications.

[0036] When the water pump 6 is working, it will pump the water source inside the mixing barrel 1 through the pumping pipe 5, and then inject the water source into the support pipe 8 through the water inlet pipe 7. When the water source enters the support pipe 8, it will enter the three-way pipe 16, and will be sprayed through the spray head 18 and the spray hole 19. There are two spray heads 18, and both are provided with spray holes 19.

[0038] The limiting ring 29 and the limiting groove 30 can limit the connection between the three-way pipe 16 and the support pipe 8, thereby preventing the three-way pipe 16 from being separated from the support pipe 8 when rotating, and at the same time facilitating the impact force generated by the water flow to drive the three-way pipe 16 to rotate.

[0039] Please see attached Figure 2 The mixing assembly includes a rotating rod 14, which is rotatably connected to the middle part of the mixing barrel 1, and a rotating rod 2 15 is rotatably connected to the middle part of the mixing barrel 1. The outer sides of the rotating rod 2 15 and the rotating rod 14 are fixedly connected with a plurality of stirring rollers 34. The outer periphery of the rotating rod 14 is fixedly connected with a pulley 11, and the outer periphery of the rotating rod 2 15 is fixedly connected with a pulley 2 12.

[0040] When the rotating rod 2 15 rotates, it can conveniently drive the pulley 2 12 to rotate. When the pulley 2 12 rotates, it will drive the pulley 1 11 to rotate at the same time through the synchronous belt 13. When the pulley 11 rotates, it will drive the rotating rod 14 to rotate. When the rotating rod 14 and the rotating rod 2 15 rotate at the same time, they will drive multiple stirring rollers 34 to move, so that the water source and fertilizer can be mixed conveniently, thereby reducing the labor intensity of personnel and improving work efficiency.

[0041] Please see attached Figure 2 The driving assembly includes a dustproof shell 9, which is fixedly connected to the top of the mixing barrel 1, a motor 10 is fixedly connected to the top of the dustproof shell 9, and the top of the rotating rod 14 is fixedly connected to the output end of the motor 10.

[0042] The dustproof shell 9 can conveniently support and fix the motor 10, thereby making the motor 10 more stable, and can conveniently drive the rotating rod 14 to rotate when the motor 10 is working.

[0043] Please see attached Figure 3 and attached Figure 4 The adjusting assembly includes a threaded rod 21, which is fixedly connected to the bottom of the support seat 20. An upper nut 24 and a lower nut 25 are bolted to the outer periphery of the threaded rod 21. An adjusting block 23 is slidably connected to the outer periphery of the threaded rod 21. A movable frame 1 26 is rotatably connected to the outer side of the support seat 20. A movable frame 27 is rotatably connected to the outer side of the adjusting block 23. One end of the movable frame 1 26 is slidably connected to the middle of the movable frame 27. A fixing assembly is provided at one end of the movable frame 27, which is used to limit and fix the adjusting assembly.

[0044] When the height of the support seat 20 is adjusted, the upper nut 24 and the lower nut 25 are manually driven to rotate. When the upper nut 24 and the lower nut 25 are rotated, the fixation of the adjustment block 23 will be loosened. After the adjustment block 23 is loosened, the adjustment block 23 can be driven to adjust up and down. When the adjustment block 23 moves, it will drive the movable frame 27 to move. When the movable frame 27 moves, it can conveniently drive the movable frame 1 26 to move at the same time. When the movable frame 1 26 moves, it will drive the support tube 8 to adjust the height through the support seat 20, so that the height of the water source spraying can be conveniently adjusted, thereby further expanding the range of the water source spraying.

[0045] Please see attached Figure 4 The fixing assembly includes a fastening plate 28, which is rotatably connected to one end of the movable frame 27. A fastening nail 22 is provided in the middle of the fastening plate 28, which is used to connect the fastening plate 28 to the ground.

[0046] The fastening plate 28 and the fastening nails 22 can conveniently connect and fix the movable frame 27, and can also facilitate the operation of personnel.

[0047] Please see attached Figure 6 and attached Figure 7 , the monitoring system includes:

[0048] Soil moisture monitoring module, which is used to monitor soil moisture in real time and provide key information about whether the soil is dry. When the soil moisture is lower than the set threshold, the system will start the irrigation function to ensure that the crops get enough water to avoid drought;

[0049] Meteorological monitoring module, which is used to monitor meteorological changes in real time, including parameters such as temperature, humidity, and wind speed. By analyzing meteorological conditions, the system can adjust the irrigation plan to prevent over-irrigation or fertilization in severe weather such as high temperature and strong wind;

[0050] Precipitation monitoring module monitors precipitation in real time. The system can detect the occurrence of precipitation and automatically stop or adjust irrigation to avoid over-irrigation.

[0051] The data processing module is used to analyze and process the monitored data and communicate it.

[0052] The soil moisture monitoring module is one of the core components of the monitoring system. It is mainly used to monitor the moisture content in the soil in real time. Soil moisture is a key factor affecting crop growth. Too dry soil will cause crop drought, and too wet soil will cause root hypoxia or pests and diseases. By monitoring soil moisture in real time, the system can dynamically adjust the irrigation amount to ensure that crops grow under optimal humidity conditions.

[0053] The meteorological monitoring module helps the monitoring system understand external climate changes by real-time monitoring of environmental meteorological parameters such as temperature, humidity, wind speed, etc. By analyzing meteorological data, the system can automatically adjust irrigation plans and fertilization strategies to ensure that crops can grow under the most suitable environmental conditions and effectively avoid water waste or excessive fertilization in extreme weather.

[0054] The data processing module is responsible for analyzing, processing and transmitting the raw data collected from various sensors such as soil moisture sensor 31, meteorological sensor 32, precipitation sensor 33, etc. Through real-time processing and analysis of data, the data processing module not only provides decision support for irrigation and fertilization control, but also ensures the efficient operation and accurate response of the monitoring system.

[0055] The meteorological monitoring module is responsible for real-time monitoring of meteorological changes in the environment, including meteorological parameters such as temperature, humidity, wind speed, and light intensity. By analyzing these data, the meteorological monitoring module can help the monitoring system automatically adjust irrigation plans and fertilization strategies to prevent excessive irrigation or fertilization in severe weather such as high temperature and strong winds, thereby improving the utilization efficiency of water resources and optimizing the crop growth environment.

[0056] Please see attached Figure 7 , the soil moisture monitoring module includes:

[0057] A data acquisition unit, which is responsible for receiving data from the soil moisture sensor 31 and converting it into a digital signal or an analog signal for further processing;

[0058] The signal processing unit is used to filter, amplify, calibrate and process the signal collected from the soil moisture sensor 31.

[0059] Please see attached Figure 1 A support frame 2 is fixedly connected to the bottom of the mixing barrel 1, which is used to support and fix the mixing barrel 1. A ladder 3 is fixedly connected to the outer wall of the mixing barrel 1 for manual climbing. A feed port 4 is fixedly connected to the top of the mixing barrel 1, which is used to add materials to the inside of the mixing barrel 1.

[0060] The support frame 2 can conveniently support and fix the mixing barrel 1, thereby making the mixing barrel 1 more stable. The ladder 3 can facilitate personnel to climb to the top of the mixing barrel 1, thereby conveniently adding water or fertilizer into the mixing barrel 1.

[0061] Working principle: When irrigating farmland, the water pump 6 will work. When the water pump 6 works, it will pump the mixed water inside the mixing barrel 1. After the water pump 6 pumps the water, it will inject the water into the support tube 8 through the water inlet pipe 7. After the water is injected into the support tube 8, it will flow upward and can be sprayed out through the spray hole 19. Because the spray hole 19 is opened on the opposite side, when spraying, the sprayed water will generate a jet force, which will drive the connecting pipe 17 and the three-way pipe 16 to rotate, realizing large-scale spraying. At the same time, under the action of the soil moisture sensor 31, the meteorological sensor 32 and the precipitation sensor 33, the crop fertilization and drip irrigation can be controlled on demand according to the climate and soil conditions.

[0062] When the water source and the fertilizer are mixed, the motor 10 is started. When the motor 10 is working, it drives the rotating rod 14 to rotate. When the rotating rod 14 rotates, it drives the pulley 11 to rotate at the same time. When the pulley 11 rotates, it drives the pulley 2 12 to rotate through the synchronous belt 13. When the pulley 2 12 rotates, it drives the rotating rod 2 15 to rotate at the same time. When the rotating rod 14 and the rotating rod 2 15 rotate at the same time, they drive multiple stirring rollers 34 to move, thereby mixing the water source and the fertilizer.

[0063] When the height of the support tube 8 is adjusted, the upper nut 24 and the lower nut 25 are manually driven to rotate. When the upper nut 24 and the lower nut 25 are rotated, the adjusting block 23 will be loosened. After the adjusting block 23 is loosened, the adjusting block 23 can be driven to adjust up and down. When the adjusting block 23 moves, the movable frame 27 will be driven to move. When the movable frame 27 moves, the movable frame 1 26 will be driven to move at the same time. When the movable frame 1 26 moves, the support tube 8 will be driven to adjust its height through the support seat 20, so that the height of the water source spraying can be adjusted.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
