Description

Technical Field

[0001] This utility model belongs to the field of drip irrigation tape technology, and in particular relates to a drip irrigation tape with adjustable drain outlet gap. Background Technology

[0002] Drip irrigation tape is a water-saving irrigation device that delivers water to the roots of crops through plastic tubing (drip irrigation pipes) via orifices or drippers on capillary tubes with a diameter of approximately 10mm. The design of drip irrigation tape allows water to drip evenly and slowly into the soil near the crop roots, reducing water evaporation and waste and improving water resource utilization efficiency. Therefore, existing drip irrigation tapes basically meet people's needs, but the following problems still exist.

[0003] Most drip irrigation tapes on the market are made of plastic tubes. When drip irrigation is performed, the drip head is inserted into the installation hole on the drip irrigation tape to carry out the drip irrigation work. However, since the gap between the installation holes is mostly fixed, it may not be possible to adjust the gap of the drip position according to the planting density of the vegetation. This may result in a single drip irrigation tape being unsuitable for drip irrigation work with different vegetation densities. Therefore, we propose a drip irrigation tape with adjustable drain outlet gap. Utility Model Content

[0004] This utility model provides a drip irrigation tape with an adjustable drain outlet gap. The drip irrigation tube slides within the adjustment cavity, and after the drip irrigation tube is inserted into one of the several sets of inlet pipes fixed on the surface of the adjustment cavity, it is convenient to adjust the drip irrigation position of the drip irrigation tape. This makes the drip irrigation tape suitable for drip irrigation of vegetation with different gaps, thus improving the application range of the drip irrigation tape.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable drain outlet gap drip irrigation tape, comprising a drip irrigation tape, wherein a plurality of adjustment cavities are inserted into the surface of the drip irrigation tape, and extension bands that adhere to the outer and inner side walls of the drip irrigation tape are fixed around the adjustment cavities; a plurality of liquid inlet pipes are fixed on the end face of the adjustment cavity near the inside of the drip irrigation tape, and each liquid inlet pipe is provided with a push plate and a sealing plug, and the push plate and the sealing plug are elastically connected to the liquid inlet pipe; sealing blocks that are fixed at the opening of the liquid inlet pipe are inserted around the sealing plug; a drip irrigation tube that penetrates the adjustment cavity is inserted into the middle of the liquid inlet pipe, and an extension block that adheres to the inside of the adjustment cavity is fixed on the surface of the drip irrigation tube.

[0006] Furthermore, the drip irrigation tube has a squeezing chamber at the end away from the inlet pipe, and an adjusting plug is threaded in the middle of the squeezing chamber. Several sets of rectangular through holes are formed around the squeezing chamber.

[0007] Furthermore, the surface of the adjusting plug is provided with a threaded groove, and the inner wall of the extrusion chamber opening is provided with an internal threaded groove that matches the adjusting plug.

[0008] Furthermore, a push rod is fixed between the push plate and the sealing plug, and a support frame fixed inside the liquid inlet pipe is sleeved on the surface of the push rod. A first spring is wound on the surface of the push rod, which abuts against the push plate and the support frame respectively.

[0009] Furthermore, all the sealing blocks are rectangular blocks, and the sealing plugs are provided with rectangular notches around their perimeter that match the sealing blocks.

[0010] Furthermore, the drip irrigation tube has a backing plate embedded in the adjustment cavity through its middle section, and the backing plate and the surface of the extension block are in contact with each other. Connecting pipes that pass through one side of the adjustment cavity are fixed around the backing plate, and extension sleeves fixed to the inner wall of the adjustment cavity are fitted on the surface of the connecting pipes. Second springs that abut against the backing plate and the connecting pipes are wound around the surface of the connecting pipes, and a pull plate is fixed at the end of the connecting pipes.

[0011] The beneficial effects of this utility model are:

[0012] 1. This adjustable drain outlet gap drip irrigation tape is equipped with an inlet pipe, an adjustment chamber, a sealing plug, a sealing block, and a push plate. When the operator pulls the drip irrigation pipe, it moves out of the inlet pipe. After the drip irrigation pipe is no longer squeezed by the push plate, the sealing plug moves into the inlet pipe, and the sealing plug and sealing block seal the inlet pipe. Then, the operator pulls the drip irrigation pipe, and it slides in the adjustment chamber to move to another inlet pipe and insert it into the other inlet pipe. The drip irrigation pipe pushes the sealing plug to move through the push plate. After the sealing plug separates from the sealing block, the other inlet pipe is opened. This allows the operator to easily adjust the drip irrigation position, making the drip irrigation tape suitable for drip irrigation of vegetation with different gaps and increasing the application range of the drip irrigation tape.

[0013] 2. The drip irrigation tape with adjustable drain outlet gap is equipped with a squeezing chamber and an adjusting plug. The operator adjusts the plug, which is threadedly engaged with the squeezing chamber, thereby changing the chamber within the squeezing chamber. By changing the chamber within the squeezing chamber, the pressure of the liquid flowing out is adjusted, thereby adjusting the spraying mode of the drip irrigation. Attached Figure Description

[0025] To further understand the utility model's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0026] Example:

[0027] Please see Figure 1 - Figure 9A drip irrigation tape with adjustable drain outlet gap includes a drip irrigation tape 1. Several sets of adjustment chambers 2 are inserted into the surface of the drip irrigation tape 1. Extension strips 4 are fixed around each adjustment chamber 2, adhering to the outer and inner walls of the drip irrigation tape 1. Several sets of inlet pipes 6 are fixed to the end face of each adjustment chamber 2 near the inside of the drip irrigation tape 1. Each inlet pipe 6 is equipped with a push plate 9 and a sealing plug 13, and the push plate 9 and sealing plug 13 are elastically connected to the inlet pipe 6. A push rod 10 is fixed between the push plate 9 and the sealing plug 13, and a support frame 11 fixed inside the inlet pipe 6 is sleeved on the surface of the push rod 10. The surface is wound with first springs 12 that abut against the push plate 9 and the support frame 11 respectively. Sealing blocks 14, fixed to the opening of the inlet pipe 6, are inserted around the sealing plug 13. A drip irrigation tube 3, penetrating the adjustment chamber 2, is inserted into the middle of the inlet pipe 6, and an extension block 5, which fits into the interior of the adjustment chamber 2, is fixed to the surface of the drip irrigation tube 3. When the operator needs to adjust the drip interval of the drip irrigation tube 3, the operator first pulls the drip irrigation tube 3, causing it to slide within the inlet pipe 6. Then, the operator pulls the drip irrigation tube 3 again, causing it to slide within the adjustment chamber 2. The drip tube 3 is moved to the front end of another inlet tube 6. After the drip tube 3 is moved to the front end of the other inlet tube 6, the operator pushes the drip tube 3 to insert it into the inlet tube 6. After the drip tube 3 is inserted into the inlet tube 6, the drip tube 3 pushes the push plate 9 to slide inside the inlet tube 6. When the push plate 9 moves, it pushes the sealing plug 13 to move through the push rod 10. When the push plate 9 pushes the push rod 10 to move, the push rod 10, which is set as a rectangular block, slides in the rectangular through hole opened in the middle of the support frame 11, so that the rectangular through hole opened in the middle of the support frame 11 restricts the push rod 10. To prevent the push rod 10 from rotating the sealing plug 13, the sealing plug 13 and the sealing block 14 are separated. When the push plate 9 moves, the push plate 9 squeezes the first spring 12, causing the first spring 12 to undergo elastic deformation. After the first spring 12 undergoes elastic deformation, it avoids the push plate 9. The push plate 9 pushes the sealing plug 13 to move through the push rod 10. The sealing plug 13 moves out of the liquid inlet pipe 6, and the rectangular through hole opened around the sealing plug 13 moves out of the surface of the sealing block 14, opening the liquid inlet pipe 6. This makes it convenient for the operator to adjust the spraying gap of the drip irrigation pipe 3.

[0028] In other embodiments, a squeezing chamber 16 is provided at the end of the drip irrigation tube 3 away from the inlet pipe 6, and an adjusting plug 15 is threadedly installed in the middle of the squeezing chamber 16. The adjusting plug 15 has a threaded groove on its surface, and an internal threaded groove matching the adjusting plug 15 is provided on the inner wall of the opening of the squeezing chamber 16. Several sets of rectangular through holes are provided around the squeezing chamber 16. When the operator needs to adjust the amount of liquid sprayed by the drip irrigation, the operator first turns the adjusting plug 15 so that the thread on the surface of the adjusting plug 15 and the internal thread on the inner wall of the squeezing chamber 16 are threadedly engaged. After the adjusting plug 15 and the squeezing chamber 16 are threadedly engaged, the adjusting plug 15 slides in the squeezing chamber 16. When the adjusting plug 15 slides in the squeezing chamber 16, the size of the rectangular through holes around the squeezing chamber 16 is adjusted, thereby adjusting the amount of drip irrigation liquid.

[0029] In other embodiments, the sealing block 14 is configured as a rectangular block, and the sealing plug 13 is provided with rectangular notches around its perimeter that match the sealing block 14. By matching the rectangular blocks of the sealing block 14 with the rectangular notches around the sealing plug 13, the rectangular notches around the sealing plug 13 can be fitted onto the surface of the sealing block 14, which is configured as a rectangular block, and the back of the sealing block 14 is in close contact with the inner wall of the rectangular notches around the sealing plug 13, thereby increasing the sealing performance of the sealing plug 13 and the sealing block 14 at the opening of the liquid inlet pipe 6.

[0030] In other embodiments, the drip irrigation tube 3 passes through the abutment plate 7 embedded in the adjustment cavity 2, and the abutment plate 7 and the surface of the extension block 5 are in contact with each other. Connecting tubes 18 passing through one side of the adjustment cavity 2 are fixed around the abutment plate 7, and extension sleeves 19 fixed to the inner wall of the adjustment cavity 2 are sleeved on the surface of each connecting tube 18. Second springs 17 are wound around the surface of each connecting tube 18, respectively abutting between the abutment plate 7 and the connecting tube 18. Pull plates 8 are fixed to the ends of each connecting tube 18. When the operator needs to adjust the position of the drip irrigation tube 3, the operator first pulls the pull plate. 8. The pull plate 8 drives the connecting pipe 18 to move, causing the connecting pipe 18 to slide within the extension sleeve 19. This sliding of the connecting pipe 18 within the extension sleeve 19 increases the contact area on one side of the adjusting cavity 2, increasing the stability of the connecting pipe 18's movement. Furthermore, as the connecting pipe 18 moves, it drives the abutment plate 7 to move, causing the abutment plate 7 to slide within the adjusting cavity 2. When the abutment plate 7 slides within the adjusting cavity 2, it compresses the second spring 17, causing the second spring 17 to undergo elastic deformation. After the spring 17 undergoes elastic deformation, the second spring 17 avoids the abutment plate 7, allowing the abutment plate 7 to slide within the adjusting cavity 2. Simultaneously, the abutment plate 7 moves off the surface of the extension block 5, and no longer abuts the drip tube 3 through the extension block 5. The operator then pulls the drip tube 3, causing the extension block 5 to move. Once the drip tube 3 is reinserted into the inlet pipe 6, the operator releases the pull plate 8. The pull plate 8 no longer compresses the second spring 17 through the connecting pipe 18, and the elastic deformation of the second spring 17 returns to normal. Then, the second spring 17 pushes the abutment plate 7 to move, causing the abutment plate 7 to slide again in the adjustment cavity 2, and the abutment plate 7 abuts against the surface of the extension block 5. The extension block 5 pushes the drip irrigation tube 3 into the liquid inlet tube 6, and the extension block 5 abuts against the inner wall of the adjustment cavity 2. At the same time, the elastic force of the second spring 17 is greater than the elastic force of the first spring 12, so when the second spring 17 pushes the abutment plate 7 to move, the abutment plate 7 pushes the extension block 5 to move. After the extension block 5 pushes the push plate 9 to move through the drip irrigation tube 3, the push plate 9 can stably squeeze the first spring 12.
