Description

Technical Field

[0001] This utility model relates to the field of irrigation device technology, specifically to an automatic control device for water-saving irrigation in farmland. Background Technology

[0002] Farmland irrigation is a technical measure to replenish the water needed by crops to ensure normal growth and achieve high and stable yields. Under natural conditions, insufficient or uneven rainfall often fails to meet the water requirements of crops. In addition, the water requirements of crops vary at different growth stages. Therefore, artificial irrigation is necessary to supplement insufficient natural rainfall and regulate the water volume in farmland. Traditional farmland irrigation is flood irrigation, which wastes water resources severely. Furthermore, traditional irrigation methods lack quantitative water supply devices and can only adjust the water intake by the size of the opening. This often leads to excessive water release or even overflow, causing crops to drown and fertilizer to be lost during the growing season, affecting normal crop growth and wasting water resources. Although existing irrigation devices can irrigate surrounding farmland by setting up multiple vertical water pipes at different locations in the farmland, this method is not uniform enough and affects the irrigation effect on crops. Therefore, a farmland water-saving irrigation automatic control device is of great practical value. Summary of the Invention

Alternatively, the limiting slip ring 4 can be replaced with several rollers evenly distributed circumferentially, each roller rolling into the annular groove, as long as it facilitates the relative movement of the hollow base 1 and the turntable 3 and has a limiting function. An irrigation component 5 is arranged on one side of the top of the turntable 3, the irrigation component 5 including a nozzle 12. A metering water supply device 6 is provided at intervals on the side of the irrigation component 5. A second water pump 8 is provided between the irrigation component 5 and the metering water supply device 6. A first water pump 7 is provided at intervals on the side of the metering water supply device 6. Water pipes are connected to the output and input ends of the first water pump 7 and the second water pump 8. The output end of the second water pump 8 is connected to the nozzle 12 of the irrigation component 5 through the water pipe. The input end of the second water pump 8 is connected to the metering water supply device 6 through the water pipe. The output end of the first water pump 7 is connected to the metering water supply device 6 through the water pipe. The first water pump 7 can be detachably connected to tap water. During the use of this device, external water is drawn into the metering water supply device 6 by the first water pump 7, and then the second water pump 8 draws the water from the metering water supply device 6 to the irrigation component 5 for irrigation. During the irrigation process, the metering water supply device 6 can realize metered irrigation, thereby avoiding the waste of water resources.

[0021] The irrigation assembly 5 includes a support plate 9. An electric telescopic rod is fixedly connected to the bottom of the support plate 9. The bottom end of the electric telescopic rod is fixedly connected to the top of the turntable 3. A mounting bracket 10 is fixedly connected to the top of the support plate 9. A swing plate 11 is rotatably connected to the inner cavity of the mounting bracket 10 via a rotating shaft. A connecting hole is horizontally provided on the swing plate 11. A nozzle 12 is fixedly connected to the inner cavity of the connecting hole. An electric hydraulic rod 13 is provided below the swing plate 11. The top and bottom ends of the electric hydraulic rod 13 are rotatably connected to end plates via pins. The two sets of end plates connected to the electric hydraulic rod 13 are respectively fixedly connected to the bottom of the swing plate 11 and the top of the support plate 9. The extension and retraction of the electric hydraulic rod 13 drives the swing plate 11 to swing, and the swing plate 11 drives the nozzle 12 to adjust the irrigation angle, thereby realizing the precise adjustment of the irrigation angle of the nozzle 12, which is beneficial to improving the irrigation effect.

[0022] The quantitative water supply device 6 includes a water tank 14. A pre-drilled hole is provided through the top of the water tank 14. A guide ring 16 is fixedly connected to the inner cavity of the pre-drilled hole. A vertical rod 17 is inserted into the inner cavity of the guide ring 16. A scale is provided on the vertical rod 17. The bottom end of the vertical rod 17 extends through the guide ring 16 into the inner cavity of the water tank 14 and is fixedly connected to a float block 15. A water injection pipe is connected to the top of the water tank 14. The water tank 14 is fixedly connected to the top of the turntable 3. When there is no river water or other water source available for pumping outdoors, water can be manually injected into the water tank 14 for irrigation operations through the water injection pipe connected to the top of the water tank 14.

[0023] Multiple sets of guide rods are evenly connected to the side wall of the float block 15. The inner wall of the water tank 14 is longitudinally provided with matching grooves at the corresponding positions of each set of guide rods. The end of each set of guide rods away from the float block 15 extends into the inner cavity of its matching groove. Through the guiding effect of multiple sets of guide rods, the float block 15 can always move in the vertical direction without tilting, thereby improving the stability of the movement of the float block 15.

[0024] The other end of the water pipe connected to the input end of water pump 28 is connected to the bottom of the side wall of water tank 14. Water pump 28 transfers the water inside water tank 14 to nozzle 12 through the water pipe for irrigation.

[0025] Water is pumped from the outside through water pump 7 and stored inside water tank 14. When in use, water is pumped out from inside water tank 14 by water pump 8 for irrigation.

[0026] Working principle:

[0027] During operation, the device uses a water pump 7 to draw water into a water tank 14. A second water pump 8 then pumps the water from the tank to the sprinkler head 12 via a connected pipe. The volume of water used in the tank is measured by a scale on the vertical rod 17, ensuring accurate water usage and preventing over-irrigation. As the sprinkler head 12 sprays water, a reduction motor 2 rotates the sprinkler head 12 via a turntable 3, ensuring even irrigation. The height of the nozzle 12 is adjusted by an electric telescopic rod, thereby expanding the irrigation range of the nozzle 12. At the same time, the electric hydraulic rod 13 can precisely adjust the irrigation angle of the nozzle 12 by swinging plate 11, which helps to improve the irrigation effect. During irrigation, the input end of the water pump 8 is disconnected from the external water source. The water tank 14 can be used as a water storage or pesticide storage device in daily use. It can be used to replenish water in drought and water shortage situations, and to spray pesticides when fertilization or pest control is needed, so as to improve the utilization rate of the structure. Alternatively, after the irrigation angle is adjusted by the reduction motor 2, the water tank 14 can be replenished by connecting to the external water source when the turntable 3 is not rotating relative to it.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
