Description

Technical Field

[0001] This utility model relates to the field of asparagus cultivation technology, and in particular to a water-saving drip irrigation device for asparagus cultivation. Background Technology

[0002] Asparagus is the seedling of Asparagus genus, a perennial herbaceous plant of the Asparagaceae family. It can be eaten as a vegetable. Before it emerges from the soil, it is white and called white asparagus. After it emerges from the soil, it is green and called green asparagus. Even if the production area is different, no matter what variety of asparagus it is, as long as it is exposed to sunlight, it will turn into green asparagus. If it is buried in the soil or shaded from the sun, it will be whiter. Asparagus needs to be irrigated by drip irrigation system when it is grown.

[0003] However, traditional drip irrigation tapes are mostly laid at a fixed height close to the ground, which cannot adapt to the changes in root distribution at different growth stages of asparagus (such as shallow roots in the seedling stage and deep roots and upward movement of underground stems in the mature stage), resulting in insufficient irrigation precision and easy to cause local waterlogging or drought. At the same time, the fixed structure is difficult to use in special scenarios such as high-ridge mounding and off-season greenhouse cultivation. The drippers are easily blocked by mud and sand and are inconvenient to maintain. In addition, existing devices lack a dynamic adjustment mechanism and cannot flexibly adjust the height of the drip irrigation tape according to the growth needs of asparagus, which affects the water and fertilizer utilization rate and the quality of asparagus (for example, if the drip irrigation tape is too low during the mounding stage of white asparagus, it will easily cause erosion of the ridge surface and soil staining of tender stems). Therefore, this utility model proposes a water-saving drip irrigation device for asparagus planting to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a water-saving drip irrigation device for asparagus cultivation, which solves the problems of fixed drip irrigation tape height, low accuracy, and inconvenient maintenance in the prior art.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a water-saving drip irrigation device for asparagus cultivation, including a main pipe, a connecting seat installed above the main pipe, drip irrigation tapes connected to both sides of the connecting seat, a plurality of drip irrigation ports provided at the bottom end of the drip irrigation tapes, a base plate installed below the drip irrigation tapes, a fixing cavity installed above the base plate, an adjustment mechanism provided inside the fixing cavity, an installation plate installed above the adjustment mechanism, and a fixing mechanism installed above the installation plate;

[0006] The adjustment mechanism includes a movable rod, a mounting groove, a positioning hole, and a positioning structure. The mounting groove is provided inside the fixed cavity, and the movable rod is provided inside the mounting groove. The top end of the movable rod extends into the interior of the mounting groove and is connected to the bottom end of the mounting plate. The positioning hole is provided inside the movable rod.

[0007] A further improvement is that multiple positioning holes are provided inside the movable rod, and these multiple positioning holes are distributed at equal intervals inside the movable rod.

[0008] A further improvement is that the positioning structure includes a mounting cavity, a pull pin, and a telescopic spring. The mounting cavity is installed above one side of the fixing cavity. A pull pin is provided through the interior of the mounting cavity. One end of the pull pin extends into the interior of the positioning hole. A telescopic spring is provided on the outer wall of the pull pin. The telescopic spring is installed inside the mounting cavity.

[0009] A further improvement is that the cross-section of the positioning hole is larger than the cross-section of the pull pin, and the positioning hole and the pull pin form a sliding structure.

[0010] A further improvement is that the fixing mechanism includes a mounting base, a fixing groove, a limiting groove, a positioning groove, and a limiting rod. The mounting base is installed above the mounting plate. The mounting base has a fixing groove inside. The drip irrigation tape is placed inside the fixing groove. One end of the mounting base has a limiting groove through it. The other end of the mounting base has a positioning groove. A limiting rod is installed through the limiting groove. One end of the limiting rod extends into the positioning groove.

[0011] A further improvement is that fixing pins are provided through both ends of the base plate, which can fix the base plate in place.

[0012] The beneficial effects of this utility model are as follows: By setting an adjustment mechanism inside the fixed cavity, the height of the drip irrigation tape can be adjusted by utilizing the interaction between the movable rod, mounting groove, positioning hole, mounting cavity, pull pin, and telescopic spring of the adjustment mechanism. This allows for flexible adjustment of the drip irrigation tape height to adapt to different root distributions and cultivation scenarios at different growth stages of asparagus, improving irrigation accuracy and thus greatly enhancing the practicality of the device. Furthermore, by setting a fixing mechanism above the mounting plate, the drip irrigation tape can be fixed by utilizing the interaction between the mounting base, fixing groove, limiting groove, positioning groove, and limiting rod of the fixing mechanism. This ensures the stability of the drip irrigation tape position, preventing displacement due to external force shaking or agricultural operations, and guaranteeing uniform water and fertilizer delivery, thereby greatly improving the stability of the device during use.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a water-saving drip irrigation device for asparagus cultivation, including a main pipe 1, a connecting seat 2 installed above the main pipe 1, drip irrigation tapes 3 connected to both sides of the connecting seat 2, a plurality of drip irrigation ports 4 provided at the bottom end of the drip irrigation tapes 3, a base plate 5 installed below the drip irrigation tapes 3, a fixing cavity 7 installed above the base plate 5, an adjustment mechanism provided inside the fixing cavity 7, an installation plate 8 installed above the adjustment mechanism, and a fixing mechanism provided above the installation plate 8.

[0020] The adjustment mechanism includes a movable rod 9, a mounting groove 10, a positioning hole 11, and a positioning structure. The mounting groove 10 is formed inside the fixed cavity 7, and the movable rod 9 is disposed inside the mounting groove 10. The top end of the movable rod 9 extends into the mounting groove 10 and is connected to the bottom end of the mounting plate 8. Multiple positioning holes 11 are formed inside the movable rod 9 and are evenly spaced. The positioning structure includes a mounting cavity 12, a pull pin 13, and a telescopic spring 14. The mounting cavity 12 is mounted above one side of the fixed cavity 7. A pull pin 13 is inserted through the mounting cavity 12, with one end extending into the positioning hole 11. The outer wall of the pull pin 13... A telescopic spring 14 is installed inside the mounting cavity 12. The cross-section of the positioning hole 11 is larger than the cross-section of the pull pin 13. The positioning hole 11 and the pull pin 13 form a sliding structure. In use, pulling the pull pin 13 disengages it from the positioning hole 11, allowing the movable rod 9 to move. The movable rod 9 is adjusted to an appropriate height according to the actual asparagus growth stage. Then, the pull pin 13 is released. The telescopic spring 14 is then subjected to elastic force, causing the pull pin 13 to extend and engage with the positioning hole 11, thus fixing the position of the movable rod 9. The height of the drip irrigation tape 3 can be adjusted flexibly to adapt to different asparagus growth stages, root distribution, and cultivation scenarios, improving irrigation accuracy and greatly enhancing the practicality of the device.

[0021] The fixing mechanism includes a mounting base 15, a fixing groove 16, a limiting groove 17, a positioning groove 18, and a limiting rod 19. The mounting base 15 is installed above the mounting plate 8. The fixing groove 16 is opened inside the mounting base 15, and the drip irrigation tape 3 is placed inside the fixing groove 16. The limiting groove 17 is opened through one end of the mounting base 15, and the positioning groove 18 is opened at the other end of the mounting base 15. The limiting rod 19 is opened through the limiting groove 17, and one end of the limiting rod 19 extends into the positioning groove 18. In use, the drip irrigation tape 3 is placed inside the fixing groove 16, the drip irrigation port 4 is aligned with the root distribution area, and then the limiting rod 19 is inserted into the limiting groove 17 and the positioning groove 18 to limit the position of the drip irrigation tape 3, ensuring that the drip irrigation tape 3 remains stable during irrigation, avoiding shaking or displacement, and preventing displacement caused by external force shaking or agricultural operations, thus ensuring uniform water and fertilizer delivery and greatly improving the stability of the device during use.

[0022] The base plate 5 has fixing pins 6 through both ends, which can fix the base plate 5 and make the device more stable during use.

[0023] Working principle: First, the operator uses the fixing pin 6 to fix the base plate 5 in a suitable position. Then, pull the pull pin 13 to disengage it from the positioning hole 11. At this time, the movable rod 9 can be moved. According to the actual growth stage of the asparagus, the movable rod 9 is adjusted to an appropriate height. Then, the pull pin 13 is released. At this time, the extension spring 14 is driven by the elastic force to extend the pull pin 13, so that the pull pin 13 engages with the positioning hole 11, completing the fixation of the position of the movable rod 9. Then, the drip irrigation tape 3 is placed inside the fixing groove 16, and the drip irrigation port 4 is aligned with the root distribution area. Then, the limiting rod 19 is inserted into the limiting groove 17 and the positioning groove 18 to limit the position of the drip irrigation tape 3, ensuring that the drip irrigation tape 3 remains stable during irrigation and avoids shaking or displacement. Finally, the water source is turned on. The water source flows through the main pipe 1, the connecting seat 2 to the drip irrigation tape 3, and drips precisely into the soil of the asparagus root area through the drip irrigation port 4 to complete the irrigation. If the height needs to be adjusted, the above operation steps can be repeated.
