Description

Technical Field

[0001] The present invention mainly relates to the technical field of irrigation equipment, and specifically relates to a farmland irrigation equipment. Background Art

[0002] The surge irrigation method is a kind of water-saving irrigation technology, which can be used for furrow irrigation or border irrigation. It changes continuous irrigation into intermittent irrigation. Through this irrigation method, the infiltration time at the head of the border ditch is shortened and the infiltration capacity is weakened, thereby reducing the total amount of infiltrated irrigation water. Therefore, the water receiving time of the front section of the border field is greatly reduced in the water flow direction, the deep leakage of irrigation water is reduced, and the irrigation uniformity, water use efficiency and irrigation effect of farmland irrigation water are greatly improved, so as to achieve the purpose of effective water saving.

[0003] The surge irrigation system generally consists of components such as a water source, a controller, a surge valve and a water distribution pipeline. Among them, the controller and the surge valve are the most core components of the whole system. At present, the surge valve and the controller of the surge irrigation system have a relatively complex structure, a relatively high price, a relatively large volume, a high failure rate of the supporting power distribution equipment and a high maintenance cost. At the same time, the controller of the system needs to be waterproof and dustproof, with a high cost and relatively high professional quality requirements for operators. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In combination with the drawings and specific embodiments, the present invention will be further described. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by this application.

[0016] Embodiment: A farm irrigation equipment AsFigures 1 - 3 As shown in the figure, a farmland irrigation device, its specific structure includes: A water tank 1, a base 2 is provided below the water tank 1, a water inlet pipe 3 is fixedly installed behind the water tank 1, water outlet pipes 4 are respectively fixedly installed on both sides of the water tank 1, an intermittent opening and closing assembly is arranged in the two water outlet pipes 4, a solenoid valve 5 is arranged on the water inlet pipe 3, the solenoid valve 5 is electrically connected to a power source, and a pressure regulating mechanism is arranged in the water tank 1. The intermittent opening and closing assembly includes a motor 6, the motor 6 is electrically connected to a power source, the motor 6 is fixedly installed on the top surface of the base 2, through holes 7 are respectively opened at the bottom of the water outlet pipe 4 close to the water tank 1, rotating shafts 8 are respectively installed in the through holes 7 by bearings, water blocking plates 9 are respectively fixedly installed on the rotating shafts 8, the outer periphery of the water blocking plates 9 is attached to the inner wall of the corresponding water outlet pipe 4, a first gear 10 is fixedly installed at the output end of the motor 6, and second gears 11 meshing with the first gear 10 are respectively fixedly installed at the lower ends of the rotating shafts 8. When this mechanism is designed for use, the output shaft of the motor 6 drives the first gear 10 connected thereto to rotate. The first gear 10 drives the corresponding rotating shafts 8 to rotate synchronously through the second gears 11 meshing therewith, and the rotating shafts 8 drive the corresponding water blocking plates 9 to rotate, so that the water blocking plates 9 can intermittently block the water outlet pipes 4, thereby realizing the intermittent opening and closing of the water outlet pipes 4, and further realizing the surge irrigation of farmland.

[0017] The two water blocking plates 9 can alternately open and close the two water outlet pipes 4. In the initial state, the two water blocking plates 9 are in a mutually perpendicular state. By setting the initial angles of the two water blocking plates 9, the two water outlet pipes 4 can be alternately opened and closed.

[0018] The pressure regulating mechanism includes a horizontal plate 12, a telescopic rod 13 is fixedly installed on the bottom surface of the inner wall of the water tank 1, the movable end of the telescopic rod 13 is fixedly connected to the bottom surface of the horizontal plate 12, and a sealing ring 14 is integrally and fixedly installed on the outer periphery of the horizontal plate 12. When the two water blocking plates 9 intermittently open and close the corresponding water outlet pipes 4, the water pressure in the water tank 1 will alternately become larger and smaller. When the water pressure in the water tank 1 becomes larger, the horizontal plate 12 will move downward under the action of the water pressure, and the air in the space between the horizontal plate 12 and the bottom of the water tank 1 is compressed. At this time, the air pressure in the space between the horizontal plate 12 and the bottom of the water tank 1 increases. When the water pressure in the water tank 1 becomes smaller, the horizontal plate 12 moves upward to reset under the action of the air pressure, and can squeeze the water flow above the horizontal plate 12, which can increase the pressure of the water in the water tank 1 and ensure the drainage pressure of this device.

The springs 15 can improve the reset effect of the horizontal plate 12 and ensure the use effect of the horizontal plate 12.

[0020] On both sides of the ground of the base 2, support frames 16 are fixedly installed respectively, and the upper ends of the support frames 16 are fixedly connected to the bottoms of the corresponding water outlet pipes 4 respectively. Through the mutual cooperation between the support frames 16 and the water outlet pipes 4, the water tank 1 can be erected above the base 2, so that there is enough space between the water tank 1 and the base 2 to install other components.

[0021] Flange plates 17 are fixedly installed at the pipe orifices of the water inlet pipe 3 and the water outlet pipe 4 respectively. Through the flange plates 17, it is convenient for users to install the water pipes for irrigation, which is convenient for use.
