Description

Technical Field

[0001] The utility model relates to the technical field of farmland drip irrigation, in particular to a combined farmland drip irrigation pipe group. Background Art

[0002] Agricultural drip irrigation is a new type of agricultural water-saving irrigation method that saves water, fertilizer and labor. At present, the drip irrigation tape used for farmland drip irrigation usually adopts a drip irrigation structure with an embedded patch. A square plastic patch is fixed on the inner wall of the drip irrigation hole. The inside of the patch is hollow and the surface of the patch is grooved. The groove wall is used as a filter to filter out impurities in the water, thereby preventing the drip irrigation hole from being blocked.

[0003] However, the drip irrigation holes of the existing embedded patch drip irrigation tape are fixed and cannot be adjusted, and the spacing between different plants may also be different. If the position of the drip irrigation hole does not correspond to the root of the plant, the plant will dry up or even die. The drip irrigation tape with a fixed drip irrigation position is difficult to be used in farmland with different planting spacings. In addition, the existing drip irrigation tapes are mostly integrated. Since the drip irrigation tapes are exposed to the sun in the natural environment for a long time during drip irrigation, they are prone to weathering and damage. In this case, the drip irrigation tape can only be replaced as a whole, and replacing other undamaged areas will undoubtedly cause a waste of resources. Utility Model Content

The cleaning column 8 is cylindrical and is welded and fixed to the stainless steel spring mesh 7. A slip ring 9 is connected to the other end of the drip irrigation belt 3. One end of the drip irrigation belt 3 connected to the slip ring 9 is used to connect another set of adjusting tubes 5. A slide groove 10 is provided inside the side wall of the adjusting tube 5. An annular groove 11 is provided on the outer wall of one end of the adjusting tube 5. A clamp 12 is sleeved in the annular groove 11. Bolts 13 are penetrated at both ends of the clamp 12. The clamp 12 is clamped in the annular groove 11. Both ends of the clamp 12 are connected by bolts 13 to form a ring shape. The bolts 13 are screwed in so that the clamp 12 squeezes the adjusting tube 5. On the one hand, the drip irrigation belt 3 is squeezed and connected and fixed to the adjusting tube 5 by the clamp 12. On the other hand, the sealing between the drip irrigation belt 3 and the adjusting tube 5 is achieved.

[0026] Specifically, the adjusting tube 5 is in the shape of a circular tube, and the adjusting tube 5 is a hard pipe made of PVC. One side of the adjusting tube 5 is fixedly connected to the drip irrigation belt 3, and the inner cavity of the adjusting tube 5 is connected to the inner cavity of the drip irrigation belt 3. There are several adjusting tubes 5 and drip irrigation belts 3. The adjusting tubes 5 are used in conjunction with the drip irrigation belt 3. One adjusting tube 5 is used in conjunction with one drip irrigation belt 3. By designing the drip irrigation belt 3 into a multi-section combined connection type, when the drip irrigation belt 3 is partially damaged after long-term use, the damaged section can be disassembled and replaced with a new one, thereby realizing the function of partial disassembly and replacement, and extending the overall service life of the drip irrigation tube group.

At this time, the limit block 15 cancels the limiting effect on the slip ring 9, and the user can pull the slip ring 9 to disengage it from the slide groove 10, thereby achieving the purpose of the detachable drip irrigation belt 3.

[0032] The method of using the present embodiment is as follows: when the user actually uses the drip irrigation pipe set to drip irrigate the farmland plants, firstly, the user lays the water pipe 1 on the main road of the farmland, connects the water pipe 1 to the water source through a water pump, connects the drip irrigation belt 3 to the joint 2 on one side of the water pipe 1, lays the drip irrigation belt 3 on the field ridge, loosens the bolt 13, pulls the slip ring 9 to slide in the slide groove 10, pulls the drip irrigation belt 3 out of the slide groove 10, adjusts the distance between adjacent drip irrigation holes 6 so that the position of the drip irrigation holes 6 corresponds to the root of the plant, tightens the bolt 13, squeezes the drip irrigation belt 3 with the clamp 12 to connect and fix it with the adjusting pipe 5, after laying, turns on the water pump, the water pump flows water into the water pipe 1, the water flows from the water pipe 1 into the drip irrigation belt 3, the water flows into the drip irrigation belt 3, passes through the stainless steel spring mesh 7 and flows out from the drip irrigation hole 6, and irrigates the plants. The roots of the plants are irrigated, and the stainless steel spring mesh 7 is used to intercept large impurities in the water flow. When the small particle impurities in the long-term drip irrigation water that pass through the stainless steel spring mesh 7 block the drip irrigation hole 6, the drip irrigation belt 3 can be pressed to squeeze the stainless steel spring mesh 7 across the drip irrigation belt 3, and the stainless steel spring mesh 7 is pushed to deform and drive the cleaning column 8 to insert into the drip irrigation hole 6 to clean the impurities blocked in the drip irrigation hole 6. When the drip irrigation belt 3 is partially damaged due to long-term use, the bolt 13 can be loosened, and then the connecting rod 16 is pulled. The connecting rod 16 drives the limit block 15 to slide in the movable groove 14, so that the limit block 15 shrinks and enters the inside of the movable groove 14, and the spring 17 is compressed. At this time, the limit block 15 cancels the limiting effect on the slip ring 9, and the user can pull the slip ring 9 to disengage the drip irrigation belt 3 from the slide groove 10, and the damaged section can be removed and replaced with a new one.
