Technical Field

[0001] This utility model relates to the field of drip irrigation device technology, specifically a drip irrigation device for farmland planting. Background Technology

[0002] Traditional drip irrigation systems for farmland mostly use fixed sprinkler designs, which cannot dynamically adjust the irrigation angle, leading to uneven crop coverage and significant water waste. While existing technologies include adjustable-angle drip irrigation devices, they often rely on complex mechanical structures or external drive devices, resulting in low adjustment precision, high maintenance costs, and susceptibility to clogging. Furthermore, fluctuations in irrigation water pressure easily affect the uniformity of drip irrigation, and existing devices lack an adaptive pressure-stabilizing structure, leading to insufficient irrigation in low-pressure areas and splashing and water loss in high-pressure areas. Therefore, there is an urgent need for a drip irrigation device with a simple structure, precise adjustable drip angle, and adaptive pressure stabilization to improve water resource utilization efficiency and farmland irrigation quality.

The drip irrigation angle can be infinitely adjusted along the guide frame 6.

[0020] like Figure 4 As shown, the fixed base 3 is provided with a connecting pipe 7 inside, the connecting base 2 is provided with a water inlet channel 8 and a drainage channel 9 inside, a water supply slip ring 10 is provided between the connecting pipe 7 and the water inlet channel 8, the upper end of the water inlet channel 8 is connected to the bottom of the regulating pipe 1, the water inlet channel 8 is provided with a water inlet check valve 11, the upper end of the drainage channel 9 is connected to the bottom of the regulating pipe 1, and the drainage channel 9 is provided with a drainage check valve 12; The lower end of the drainage channel 9 is provided with a connecting hose 13, and the drip irrigation nozzle 5 is connected to the outer end of the connecting hose 13.

The water inlet channel 8 and the water outlet channel 9 are set separately and do not affect each other. When the telescopic piston moves upward, the backflow flows upward through the water inlet check valve 11, and when the telescopic piston moves downward, the water flow flows outward through the water outlet check valve 12.

[0022] like Figure 4 As shown, the telescopic piston includes a telescopic rod 14 and a sealing plug 15. The sealing plug 15 is slidably disposed inside the regulating tube 1. The fixed end of the telescopic rod 14 is disposed outside the regulating tube 1.
