Description

Technical Field

[0001] This utility model relates to the field of precision control of drip irrigation under corn film, and in particular to a precision control device for drip irrigation under corn film. Background Technology

[0002] Corn cultivation: Maize is a plant belonging to the Poaceae family and the genus Zea. Commonly known as corn, it is a tall annual herb with erect, usually unbranched stalks, reaching a height of 1-4 meters. Drip irrigation is commonly used for watering corn. Therefore, a drip irrigation system is necessary when cultivating corn. Drip irrigation uses plastic pipes to deliver water to the roots of the crop through orifices or drippers on capillary tubes with a diameter of about 10mm for localized irrigation. It is the most effective water-saving irrigation method in arid and water-scarce areas, with a water utilization rate of up to 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation. It can also be combined with fertilization to more than double fertilizer efficiency. It is suitable for irrigating fruit trees, vegetables, cash crops, and greenhouses. In arid and water-scarce areas, it can also be used for irrigating field crops. Its disadvantage is that the drippers are prone to scaling and clogging, therefore, strict filtration of the water source is necessary.

[0003] Currently, Chinese patent CN219002724U discloses a precision water and fertilizer control system for shallow-buried drip irrigation of corn, including a weighing scale. A control panel is located on one side of the outer wall of the weighing scale, a hinge is connected to one side of the outer wall of the control panel, and a protective door is connected to the other side of the outer wall of the hinge. This precision water and fertilizer control system for shallow-buried drip irrigation of corn, through the setup of the weighing scale, control panel, hinge, protective door, and sealing ring, allows the weighing scale to roughly calculate the amount of fertilizer-water mixture needed based on the amount of land to be irrigated, thus performing a preliminary weighing. The data from the weighing is then recorded via the control panel. After recording the weight of the water and fertilizer in each mixing tank... This device, while solving the aforementioned problems, also presents the following issues: irrigation relies solely on a water pump, making it impossible to precisely control the drip irrigation based on the different heights of the corn roots. Furthermore, the fixed connection between the drip irrigation pipes and the water pump without diversion causes severe water accumulation in these areas, while other areas remain under-irrigated. Prolonged waiting for water to seep in and diffuse significantly slows down the irrigation process. Therefore, a new type of precision drip irrigation device for corn under plastic film is needed. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome the shortcomings of existing devices, which rely solely on water pump regulation for irrigation, making it impossible to perform precise drip irrigation based on the different heights of corn roots. Furthermore, the fixed connection between the drip irrigation pipe and the water pump without diversion causes severe water accumulation in some areas while other areas are under-irrigated, resulting in prolonged waiting for water to seep in and diffuse in the same area, which greatly slows down the irrigation progress. This invention provides a precision control device for drip irrigation of corn under plastic film.

In this way, the drip head at the bottom can accurately adapt to the corn root system at different heights, achieving precise drip irrigation for different areas and fully meeting the water needs of various corn growth zones.

[0012] By activating the regulating water pump, a stable suction and pressure are generated, causing the well-mixed water and fertilizer solution in the drip irrigation funnel to flow smoothly into the connecting hose along the water supply pipe. The solution continues to be transported along the connecting hose, smoothly reaching the water distribution seat. The water distribution seat, with its ingenious diversion structure, evenly distributes the incoming water and fertilizer solution to each drip irrigation rod. Finally, the solution drips precisely from the drip head at the end of the drip irrigation rod onto the roots of the corn under the mulch film. Furthermore, the regulating water pump has a flexible speed adjustment function, allowing operators to easily and accurately control the flow rate according to the different irrigation needs of the corn at different growth stages, achieving scientific irrigation.

A sealing ring 706 is fixedly mounted at the connection between the regulating water pump 704 and the connecting hose 705. When the regulating water pump 704 is turned on, it generates stable suction and pressure, causing the uniformly mixed water and fertilizer solution in the drip irrigation funnel 701 to flow smoothly into the connecting hose 705 along the water supply pipe 703. The solution is continuously transported along the connecting hose 705 and smoothly reaches the water distribution seat 604.

[0018] The subsurface irrigation control device 6 includes an adjustment knob 601, an adjustment screw 602, a shaft seat 603, a water distribution seat 604, drip irrigation rods 605, and drip irrigation heads 606. The adjustment screw 602 is fixedly mounted on the bottom surface of the adjustment knob 601. The shaft seat 603 is fixedly mounted on the bottom surface of the adjustment screw 602.

The solution continues to travel along the connecting hose 705, smoothly reaching the water distribution seat 604. The water distribution seat 604, with its ingenious diversion structure, evenly distributes the incoming water-fertilizer solution to each drip irrigation rod 605. Finally, the solution drips precisely from the drip head 606 at the end of the drip irrigation rod 605 onto the corn roots under the mulch film. Furthermore, the regulating water pump 704 has a flexible speed control function, allowing operators to easily and precisely adjust the flow rate according to the varying irrigation needs of the corn at different growth stages, achieving scientific irrigation.
