Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation, and in particular to an Internet of Things agricultural spray irrigation device for smart agriculture. Background Art

[0002] Irrigation is a technical measure to replenish the water needed by crops. To ensure normal crop growth and high and stable yields, crops must be supplied with sufficient water. Under natural conditions, insufficient or unevenly distributed precipitation often fails to meet the crop's water requirements. Therefore, artificial irrigation is necessary to supplement the lack of natural rainfall. Irrigation, i.e., using water to irrigate the land, requires the principle that the amount, frequency, and timing of irrigation should be determined based on the water requirements of the medicinal plant, its growth stage, climate, and soil conditions. Irrigation should be timely, appropriate, and reasonable. It can be divided into pre-sowing irrigation, seedling-stimulating irrigation, growing season irrigation, and winter irrigation.

[0003] Simply put, the Internet of Things is an Internet where everything is connected. It is an extension and expansion of the Internet. With the development of science and technology, the application fields of the Internet of Things involve all aspects, including agricultural irrigation in agriculture. Agricultural irrigation mainly refers to irrigation operations in agricultural farming areas.

[0013] Furthermore, an elastic member is provided between the abutment block and the rotating block, the rotating block is fixed to the outer surface of the connecting pipe, the outer shape of the rotating seat is convex, and its inner side is hollow, and the outer surface of the abutment block is fixed with an anti-slip pad that abuts against the inner side of the rotating seat.

[0014] Furthermore, the number of the abutment blocks, elastic members and connecting arms are two, and the two abutment blocks are symmetrically arranged. A connecting rod connected to the transmission member is fixed on the outer wall of the sliding sleeve. The transmission member includes a rotating shaft, and a gear is fixed at one end of the rotating shaft.

A valve fixed to the end of the rotating shaft is rotatably installed inside the delivery pipe.

[0018] Compared with the existing technology, the present invention provides an IoT agricultural spray irrigation device for smart agriculture, which has the following beneficial effects:

[0019] 1. This IoT agricultural spray irrigation equipment for smart agriculture uses the change in pipe cross-sectional area at the throat and, based on the principles of fluid mechanics, increases the water flow rate and reduces the pressure, achieving a natural pressurization effect. It does not require additional complex pressurization equipment. It has a simple structure and can ensure that the water flow obtains sufficient pressure to enter the irrigation component, meeting the basic irrigation requirements for water pressure, reducing equipment costs and energy consumption. The negative pressure generated during the pressurization process can be sucked into the liquid medicine storage tank through the valves of the dosing pipe 1 and the dosing pipe 2, realizing automatic mixing of the liquid medicine and water. There is no need for manual addition of liquid medicine, which improves the degree of automation of irrigation operations.

[0020] 2. This smart agriculture IoT agricultural spray irrigation equipment, after the liquid medicine is initially mixed with the main water flow at the throat, enters the expansion tube. The expansion tube provides sufficient space and time for further mixing of the liquid medicine and water, so that the two can be fully mixed and evenly mixed, ensuring that the liquid medicine can act evenly on the irrigation area during irrigation, improving the irrigation effect and liquid medicine utilization rate.

[0021] 3. The IoT agricultural spray irrigation equipment for smart agriculture has a horizontally arranged nozzle and a connecting pipe that is rotatably connected to the top water pipe. When water enters the nozzle and overflows and is ejected from the nozzle, the thrust generated by the water flow drives the nozzle to rotate. This rotary spraying method can expand the irrigation area and make irrigation more uniform. Compared with traditional fixed sprinklers, it can effectively reduce irrigation blind spots and improve irrigation efficiency. Rotation is achieved through water flow thrust, and no additional power drive device is required. The structure is simple, which reduces the probability of failure and maintenance costs, while improving the reliability and stability of the system.

[0022] 4. The IoT agricultural spray irrigation equipment for smart agriculture uses a nozzle that rotates to drive the connecting pipe, which in turn drives the rotating block to rotate. Under the action of centrifugal force, the abutment block is thrown outward, and the anti-slip pad on it rubs against the inner wall of the rotating seat. The friction torque generated drives the rotating seat to rotate. The rotating seat uses the synchronous parts to drive the stirring to stir the medicine inside the liquid storage tank, realizing the automation of the liquid stirring, eliminating the need for manual stirring, saving labor costs, and at the same time ensuring that the liquid medicine is always in a uniformly mixed state during the storage process, thereby improving the quality of the liquid medicine.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1 to 6In this embodiment, an IoT agricultural spray irrigation device for smart agriculture includes an irrigation device for agricultural spraying, the irrigation device includes an irrigation component 1 and a water delivery component 2 arranged on the bottom side of the irrigation component 1; the irrigation component 1 includes a nozzle 11, and both ends of the nozzle 11 are detachably installed with plugs 12. The plugs 12 can be detachably installed at both ends of the nozzle 11. This design greatly facilitates the maintenance and overhaul of the equipment. When the nozzle 11 is clogged or damaged, the inside of the nozzle 11 can be easily cleaned or parts replaced by removing the plug 12. At the same time, if the nozzle 11 needs to be upgraded or modified according to different irrigation needs in the future, such as adding an internal structure to optimize the water flow distribution, the detachable plug 12 also makes the operation more convenient, providing convenient conditions for the expansion and upgrade of the equipment. The plug 12 can be fixed by a thread. The nozzle 11 has multiple spray holes 13 inside. It should be noted that there are two plugs 12. The irrigation assembly 1 and the water delivery assembly 2 are arranged in the X and Y axis directions. The nozzle 11 is hollow inside, and its two ends are connected and blocked by two plugs 12. The nozzle 11 has multiple spray holes 13 inside. By rationally designing the number, size, and distribution of the spray holes 13, precise control of the irrigation water volume and irrigation range can be achieved. Different crops have different water requirements at different growth stages. The multiple spray holes 13 can be opened or closed according to actual needs, or the water output of each spray hole 13 can be adjusted to meet diverse irrigation needs and improve the utilization efficiency of water resources.

[0032] Furthermore, the rational structural design of the irrigation assembly 1 and the water delivery assembly 2 facilitates the installation of various sensors. For example, a flow sensor can be installed on the nozzle 11 to monitor the water output of each nozzle 13 in real time; a pressure sensor can be installed in the water delivery assembly 2 to monitor changes in water pressure; and a water quality sensor can be installed to detect indicators such as the pH and salinity of the irrigation water. These sensors can collect a wealth of irrigation-related data, providing a fundamental data source for the IoT system. IoT technology can connect irrigation equipment to cloud servers or control centers. Operators can remotely monitor the operating status of the irrigation equipment, such as the water flow of the nozzle 11, the water pressure of the water delivery assembly 2, and the mixing ratio of the liquid medicine, using terminal devices such as mobile phones and computers. Furthermore, based on the real-time data collected and the growth needs of the crops, operators can remotely adjust the parameters of the irrigation equipment, such as opening or closing specific nozzles 13, adjusting the operating status of the pressurizing element to change the water pressure, and controlling the amount of liquid medicine drawn into the dosing pipe 26, thus achieving intelligent and precise control of the irrigation process.

[0033] A transmission structure 4 and a support component 3 for support are provided on the water delivery component 2. A liquid storage structure 5 connected to the water delivery component 2 and cooperating with the transmission structure 4 is provided on the support component 3. The water delivery component 2 includes two water delivery pipes 21 arranged vertically. A pressurizing member is provided between the two water delivery pipes 21. A communicating pipe 24 fixed to the nozzle 11 is rotatably installed at the top end of the top water delivery pipe 21. A first chemical addition pipe 26 connected to the liquid storage structure 5 is installed on the pressurizing member. The bottom end of the bottom water delivery pipe 21 is flange-connected to a connecting pipe 25.

[0034] Specifically, the pressurizing member includes two expansion pipes 22. A throat pipe 23 is fixed between the two expansion pipes 22. The two ends of the two expansion pipes 22 away from each other are respectively fixedly connected to the adjacent ends of the two water delivery pipes 21. One end of the first chemical addition pipe 26 is fixedly connected to the throat pipe 23. The pressurizing member adopts a combined structure of two expansion pipes 22 and a throat pipe 23 to achieve efficient pressurization by using the principle of fluid mechanics. When water flows through the throat pipe 23, due to the reduction of the pipe cross-sectional area, the water flow velocity increases and the pressure decreases, resulting in pressure recovery and flow velocity adjustment in the subsequent expansion pipes 22, enabling the water flow to obtain sufficient pressure to enter the irrigation component 1. At the same time, the first chemical addition pipe 26 is fixedly connected to the throat pipe 23, and the negative pressure generated during the water flow pressurization can automatically suck the liquid medicine into the throat pipe 23 to be mixed with the main water flow, achieving automatic and uniform mixing of the liquid medicine and water, and improving the efficiency and effect of irrigation fertilization or pesticide application.

[0035] The support component 3 includes a support frame 31 with a U-shaped outer shape and a base 32 welded to the bottom side of the support frame 31. Both water delivery pipes 21 are fixedly connected to the support frame 31. The base (32) is fixed to the ground.

[0036] To achieve automatic liquid infusion, the transmission structure 4 includes a rotating seat 41 rotating on the outer surface of the top water delivery pipe 21. A rotating block 42 is arranged inside the rotating seat 41. A sliding sleeve 43 sleeved on the outer surface of the communicating pipe 24 is arranged above the rotating block 42. An abutting block 44 intermittently abuting against the inner side of the rotating seat 41 is arranged on the side of the rotating block 42. A connecting arm 45 is hinged between the abutting block 44 and the sliding sleeve 43. Among them, an elastic member 46 is arranged between the abutting block 44 and the rotating block 42. The elastic member 46 is composed of a guide rod and a spring. The rotating block 42 is fixed to the outer surface of the communicating pipe 24. The rotating seat 41 has a convex-shaped outer shape and is hollow inside. An anti-slip pad abutting against the inner side of the rotating seat 41 is fixed to the outer surface of the abutting block 44.

[0037] Specifically, the number of the abutting blocks 44, the elastic members 46 and the connecting arms 45 is two, and the two abutting blocks 44 are symmetrically arranged. A connecting rod 47 connected to the transmission member 48 is fixed to the outer wall of the sliding sleeve 43. The transmission member 48 includes a rotating shaft 481. A gear 482 is fixed to one end of the rotating shaft 481. A tooth plate 483 fixed to the bottom end of the connecting rod 47 is externally engaged with the gear 482.

[0038] The rotating base 41 is rotatably mounted on the outer surface of the top water pipe 21. The rotating block 42 is fixed to the outer surface of the connecting pipe 24. When the connecting pipe 24 rotates due to the water flow, the rotating block 42 is driven to rotate synchronously. The abutment blocks 44 on the side of the rotating block 42 are swung outward under the action of centrifugal force, intermittently contacting the inner side of the rotating base 41. The anti-slip pads increase friction, ensuring that the rotation of the rotating block 42 is reliably transmitted to the rotating base 41, ensuring the stability of the rotational power transmission. The liquid storage structure 5 includes a liquid storage tank 51 fixedly mounted on the exterior of the support assembly 3. A stirring rod 53 is rotatably mounted within the liquid storage tank 51 and extends outward. A synchronization member is provided between the rotating base 41 and the stirring rod 53. Specifically, the synchronization member comprises two synchronous pulleys 49 of different sizes and a synchronous belt 410 that is connected between the two synchronous pulleys 49. The two synchronous pulleys 49 are respectively fixed to the rotating base 41 and the outer surface of the stirring rod 53. The rotating base 41 and the stirring rod 53 are connected by a synchronous member. When the rotating base 41 rotates, the stirring rod 53 is driven to rotate synchronously via the synchronous belt 410, thereby automatically stirring the liquid medicine in the liquid storage tank 51. This design does not require an additional power source to drive the stirring rod, but utilizes the rotational force of the water flow in the irrigation system, reducing energy consumption and equipment costs.

[0039] In addition, continuous stirring keeps the liquid medicine in the liquid storage tank 51 in a uniformly mixed state at all times, ensuring that the concentration of the liquid medicine sucked into the dosing pipe 26 is consistent each time, thereby improving the uniformity and effect of irrigation and fertilization or drug application, which is beneficial to the growth of crops.

[0040] A second dosing tube 52 is disposed between the liquid storage tank 51 and the first dosing tube 26. The second dosing tube 52 includes a delivery tube 521 fixed therebetween. A valve 522, fixed to the end of the rotating shaft 481, is rotatably mounted within the delivery tube 521. The sleeve 43 is connected to the transmission member 48 (comprising the rotating shaft 481, the gear 482, and the toothed plate 483) via a connecting rod 47. When the connecting tube 24 rotates, driving the sleeve 43 up and down, the connecting rod 47 causes the toothed plate 483 to move up and down, thereby rotating the gear 482 and the rotating shaft 481, thereby opening or closing the valve 522 and adjusting its opening. This mechanical transmission method enables precise control of the valve 522, accurately adjusting the flow rate of the medicinal solution in the second dosing tube 52 according to actual needs, and meeting the medicinal solution needs of different crops at different growth stages. Compared with electronically controlled valves, this mechanical flow regulation structure has higher reliability and stability, is unaffected by factors such as electromagnetic interference, and is particularly suitable for outdoor agricultural environments.

[0041] The working principle of the above embodiment is:

[0042] Water enters the water delivery assembly 2 from the connecting pipe 25 connected to the bottom flange of the bottom water delivery pipe 21. The water flows through the pressurizing member between the two water delivery pipes 21. When the water flows through the throat pipe 23, due to the change in the cross-sectional area of ​​the pipe, according to the principles of fluid mechanics, the flow rate increases and the pressure decreases, achieving a pressurization effect, so that the water flow obtains sufficient pressure to enter the irrigation assembly 1. The negative pressure is sucked into the liquid medicine in the storage tank 51 through the valves 522 of the dosing pipe 1 26 and the dosing pipe 2 52. The liquid medicine is initially mixed with the main water flow in the throat pipe 23 and further mixed evenly in the subsequent expansion pipe 22.

[0043] After the water enters the nozzle 11, it overflows and is sprayed out from the nozzle hole 13. Since the nozzle 11 is arranged horizontally and the connecting pipe 24 is rotatably connected to the top water pipe 21, the water entering the nozzle 11 will generate thrust, which will drive the nozzle 11 to rotate, thereby achieving spray irrigation.

[0044] The rotation of the nozzle 11 drives the connecting pipe 24 to rotate, and the rotation of the connecting pipe 24 drives the rotating block 42 to rotate. The rotation of the rotating block 42 drives the abutting block 44. Under the action of centrifugal force, the abutting block 44 is thrown outward, and the anti-slip pad on it rubs against the inner wall of the rotating seat 41. The friction torque overcomes the resistance and drives the rotating seat 41 to rotate. When the rotating seat 41 rotates, the synchronous member drives the stirring 53 to mix the medicine inside the liquid storage tank 51, stirring the liquid medicine in the liquid storage tank 51 to ensure uniform mixing and ensure the quality of the liquid medicine.

[0045] In addition, under the action of centrifugal force, when the abutment block 44 expands outward, it drives the sleeve 43 to move downward through the connecting arm 45. The downward movement of the sleeve 43 drives the transmission member 48 through the connecting rod 47, so that the gear plate 483 engages with the gear 482 and drives the valve 522 through the rotating shaft 481, thereby adjusting the opening of the dosing tube 52 and realizing automatic control of the drug absorption amount.

[0046] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
