[0002] Traditional farmland irrigation relies on manual water diversion and irrigation, which consumes a lot of manpower and time, especially in large-scale planting scenarios, where labor costs account for a significant proportion.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing irrigation devices lack a structure for modularly connecting and extending pipelines. This makes it difficult to conveniently increase pipeline length and branches when farmland expands or planting area layout is adjusted. Instead, a completely new irrigation network must be planned and laid, which increases the cost of manpower, materials, and time significantly.

[0004] Therefore, an automatic irrigation device for agricultural planting is proposed. Utility Model Content

This makes it impossible to conveniently increase the length and branches of pipelines when the farmland area expands or the planting area layout is adjusted. Instead, a completely new irrigation network must be planned and laid, which increases the cost of manpower, material resources and time.

[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] An automatic irrigation device for agricultural planting includes an installation plate 1, four support columns 2 are fixedly connected to the top of the installation plate 1, a water storage tank 3 is welded to the top of the support columns 2, a timing mechanism 4 is fixedly connected to the left side of the water storage tank 3, and an irrigation mechanism 5 is fixedly connected to the left side of the timing mechanism 4.

[0027] The irrigation mechanism 5 includes a diversion pipe 51, a one-way valve 52, a connecting plate 53, a connecting pipe 54, an extension pipe 55, a sealing cap 56, and a nozzle 57. The diversion pipe 51 is fixedly connected to the left side of the timing mechanism 4. The one-way valve 52 is installed on the left side of the diversion pipe 51. The connecting plate 53 is fixedly connected to the left side of the diversion pipe 51 and the right side of the connecting pipe 54, respectively. The connecting pipe 54 is fixedly connected to the left side of the diversion pipe 51. The extension pipe 55 is threadedly connected to the left side of the connecting pipe 54. The sealing cap 56 is threadedly connected to the left side of the extension pipe 55. The nozzle 57 is respectively located at the bottom of the connecting pipe 54 and the extension pipe 55.

[0028] In this embodiment: the mounting plate 1 supports and limits the support column 2 and the irrigation mechanism 5. The support column 2 supports and limits the water storage tank 3. The water storage tank 3 stores a certain amount of water to cope with short-term drought or insufficient water supply, ensuring continuous irrigation. It can also collect natural rainfall through the rain inlet 7 at the top, realizing water resource recycling and reducing irrigation costs. The diversion pipe 51 distributes the water from the booster pump 46 to multiple connecting pipes 54 to realize simultaneous irrigation in multiple areas and improve irrigation efficiency. The one-way valve 52 prevents irrigation water backflow and avoids the backflow of residual water in the pipeline to contaminate the water storage tank when the water supply is interrupted. The water tank 3 and the connecting plate 53 adopt a flange connection design to provide a stable pipe interface. The connecting pipe 54 delivers water from the branch pipe 51 to each irrigation area. The extension pipe 55 achieves modular expansion of pipe length through threaded connection. The layout can be adjusted according to the length of farmland, making it easy to add irrigation range when the planting area expands without having to lay the entire pipe again, reducing expansion costs. The sealing cap 56 can seal the opening of the last extension pipe 55 to prevent debris from entering and clogging the pipe, reducing maintenance frequency. The nozzles 57 are distributed at the bottom of the extension pipe 55 and the connecting pipe 54 to achieve large-area coverage irrigation.

[0029] Specifically, such as Figure 3 , Figure 4 As shown, the timing mechanism 4 includes a mounting housing 41, a rain sensor 42, a drain pipe 43, a solenoid valve 44, a water outlet pipe 45, a booster pump 46, and a PLC controller 47. The mounting housing 41 is welded to the left side of the water storage tank 3.

[0030] Specifically, such as Figure 3 , Figure 4 As shown, the rain sensor 42 is installed inside the mounting housing 41, the detection end of the rain sensor 42 is installed on the top of the mounting housing 41, the drain pipe 43 is fixedly connected to the bottom of the water storage tank 3, the solenoid valve 44 is installed at the bottom of the drain pipe 43, and the outlet pipe 45 is fixedly connected to the bottom of the solenoid valve 44.

[0031] Specifically, such as Figure 3 , Figure 4 As shown, the booster pump 46 is installed on the top of the mounting plate 1, the bottom left side of the outlet pipe 45 is fixedly connected to the right side of the booster pump 46, the left side of the booster pump 46 is fixedly connected to the left side of the diversion pipe 51, and the PLC controller 47 is installed on the front side of the water storage tank 3.

[0032] In this embodiment: the mounting shell 41 provides physical protection for the internal rain sensor 42, resisting ultraviolet rays and rainwater erosion, and extending the service life of the equipment. The rain sensor 42 monitors the rainfall in real time. When the detected rainfall reaches the set threshold, the PLC controller 47 automatically closes the solenoid valve 44 to avoid repeated irrigation. The drain pipe 43 can drain the water inside the water storage tank 3. The solenoid valve 44 is controlled by the electrical signal of the PLC controller 47 to realize rapid opening and closing and control the start and stop of irrigation. The outlet pipe 45 connects the solenoid valve 44 and the booster pump 46 to deliver water to the irrigation mechanism 5. The booster pump 46 provides the pressure required for irrigation to ensure that the water flows to the remote nozzle 57. It is linked with the PLC controller 47 and can automatically adjust the pump speed according to the size of the irrigation area. The PLC controller 47 stores preset irrigation programs and controls the solenoid valve 44, the one-way valve 52 and the booster pump 46 according to the preset time.

[0033] Specifically, such as Figure 3 As shown, a protective housing 6 is snapped onto the surface of the PLC controller 47, and the surface of the protective housing 6 is coated with an anti-corrosion coating.

[0034] Specifically, such as Figure 5 As shown, the top of the water storage tank 3 is provided with a rain inlet 7, and a filter plate 8 is welded to the top of the water storage tank 3. The surface of the filter plate 8 is coated with an anti-corrosion coating.

[0035] In this embodiment: by setting a protective shell 6, physical protection is provided for the PLC controller 47 to prevent rainwater and dust from entering and extend the service life of the controller. By setting an anti-corrosion coating, it can resist the erosion of chemical substances in the agricultural environment and reduce the failure rate. By setting a rain inlet 7, the rainwater collection area of ​​the water storage tank 3 is increased and the water resource collection efficiency is improved. By setting a filter plate 8, it prevents leaves, mud and other debris from entering the water storage tank 3, avoids clogging of pipes and nozzles 57, and reduces the maintenance frequency. By setting an anti-corrosion coating, the corrosion resistance is enhanced, adapting to the weak acidity of rainwater and extending the service life of the filter plate 8.

[0036] Specifically, such as Figure 5 As shown, a filling pipe 9 is fixedly connected to the right side of the water storage tank 3, and a plug cap 10 is snapped into the top of the inner side of the filling pipe 9.

[0037] Specifically, such as Figure 5 As shown, a reinforcing base 11 is fixedly connected to the bottom of the pressure pump 46, and the bottom of the reinforcing base 11 is fixedly connected to the top of the mounting plate 1.

[0038] In this embodiment: by setting the filling pipe 9, when there is insufficient rainwater, the external water source can be connected through the filling pipe 9 to ensure sufficient irrigation water. By setting the plug 10, the filling pipe 9 is sealed to prevent dust and insects from entering the water storage tank 3 and to keep the water quality clean. By setting the reinforcing seat 11, the installation stability of the booster pump 46 is enhanced, the vibration and noise during operation are reduced, and the service life of the pump body is extended.

[0039] Working principle: First, the operator opens the cap 10 and fills the water tank 3 with irrigation water through the filling pipe 9. Next, the operator connects the connecting pipe 54 to the branch pipe 51 through the connecting plate 53. Then, the operator connects multiple extension pipes 55 according to the length of the farmland. When the extension pipe 55 extends to the length of the farmland, the operator threads the sealing cap 56 to the opening of the last extension pipe 55 to seal it. After that, the rainfall sensor 42 monitors the rainfall in real time and transmits the data to the PLC controller 47. The PLC controller 47 determines whether to start the irrigation process based on the preset irrigation time and rainfall threshold. When irrigation conditions are met, the PLC controller 47 starts the solenoid valve 44 and the booster pump 46. Water in the water tank 3 flows into the booster pump 46 through the drain pipe 43 and the outlet pipe 45. At this time, the booster pump 46 adjusts its pump speed under the linkage control of the PLC controller 47 to provide pressure for the water flow. The pressurized water enters the diversion pipe 51 of the irrigation mechanism 5. The diversion pipe 51 distributes the water to multiple connecting pipes 54. Finally, the nozzle 57 sprays the water evenly onto the roots or leaves of the crop to irrigate it. When the set irrigation threshold is reached, the PLC controller 47 controls the booster pump 46 and the solenoid valve 44 to close, waiting for the next working time.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
