Description

Technical Field

[0001] This utility model relates to the field of drip irrigation pipe technology, specifically a micro-pressure constant flow drip irrigation pipe. Background Technology

[0002] Drip irrigation is a highly efficient water-saving irrigation device that delivers water and nutrients directly and slowly to the crop root zone through drippers in the form of droplets or fine streams. This precise delivery method minimizes water evaporation and deep seepage losses, effectively saving water and energy, and promoting increased crop yield and quality. It is one of the core technologies of modern precision agriculture.

[0003] In existing drip irrigation systems, the drippers are permanently fixed inside the pipe during manufacturing, and the dripper spacing is predetermined at the factory and cannot be changed. This leads to irrigation blind spots or water waste when the plant spacing of the user's crops does not match the preset dripper spacing, resulting in extremely poor flexibility. To address this, we provide a low-pressure constant-flow drip irrigation system. Utility Model Content

[0004] This utility model provides a micro-pressure constant flow drip irrigation pipe that can adjust the dripper spacing by setting up multiple water outlets and a movable water outlet device. By sealing unused water outlets with a sealing device, water cannot be discharged, thus solving the problem of fixed dripper positions in traditional drip irrigation pipes, which causes irrigation blind spots and water waste.

[0005] To achieve the above objectives, a micro-pressure constant flow drip irrigation pipe is provided, comprising a drip irrigation pipe body, a T-shaped groove formed on the outer surface of the drip irrigation pipe body, a water outlet provided on the front side of the drip irrigation pipe body, a connecting groove formed on the front side of the drip irrigation pipe body, the connecting groove being located outside the water outlet, a sealing ring being connected to the bottom end of the connecting groove, a water outlet device provided on the outside of the drip irrigation pipe body, and a sealing device provided on the front side of the water outlet.

[0006] According to the aforementioned micro-pressure constant flow drip irrigation pipe, the sealing device includes a cover plate, a connecting plate, and a rubber plug. The cover plate is fixedly connected to one end of the connecting plate, the connecting plate is threadedly connected inside the connecting groove, the bottom end of the connecting plate is in contact with a sealing ring, and the rubber plug is fixedly connected to the inner end face of the cover plate and fits inside the water outlet.

[0007] According to the aforementioned micro-pressure constant flow drip irrigation tube, the rubber stopper is located inside the connecting disc, and the outer surface of the connecting disc near the cover plate is knurled.

[0008] According to the micro-pressure constant flow drip irrigation pipe, the water outlet device includes a support plate, a connecting cover, a connecting rod, a T-block, a dripper, a first fixed arc block, a second fixed arc block, a first fixed plate, a second fixed plate, bolts and nuts. The support plate is fixedly connected to the outer surface of the front side of the connecting rod, and the connecting cover and the water outlet are threaded together.

[0009] According to the micro-pressure constant flow drip irrigation pipe, the connecting cap is threadedly connected to the inside of the support plate, the connecting rod is fixedly connected to the outer surface of the front side of the T-block, and the T-block is slidably connected to the inside of the T-groove.

[0010] According to the micro-pressure constant flow drip irrigation tube, the drip head is fixedly connected inside the connecting cover, the first fixing arc block is movably connected to the rear outer surface of the support plate near the top, and the second fixing arc block is movably connected to the rear outer surface of the support plate near the bottom.

[0011] According to the micro-pressure constant flow drip irrigation pipe, the first fixing plate is fixedly connected to the lower surface of the first fixing arc block away from the support plate, and the second fixing plate is fixedly connected to the upper surface of the second fixing arc block away from the support plate.

[0012] According to the micro-pressure constant flow drip irrigation tube, holes are opened on the surfaces of the first fixing plate and the second fixing plate, the bolt passes through the holes opened on the surfaces of the first fixing plate and the second fixing plate, the nut is fixedly connected to the lower surface of the second fixing plate, and the bolt and the nut are threadedly connected.

[0013] The beneficial effects of this utility model are as follows: by setting up multiple water outlets in conjunction with a movable water outlet device, the purpose of adjusting the dripper spacing can be achieved. By using a sealing device to block unused water outlets, water cannot be discharged, thus solving the problem of fixed dripper positions in traditional drip irrigation pipes, which causes irrigation blind spots and water waste.
