Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology, specifically to a water-saving drip irrigation device for agriculture. Background Technology

[0002] Traditional agricultural irrigation methods, such as flood irrigation, result in significant water waste and low utilization efficiency. To address the problem of water scarcity, drip irrigation technology has emerged. This technology uses a pipeline system and drippers installed at the ends to precisely and evenly deliver water and nutrients directly to the soil around the crop roots in the form of water droplets.

[0003] Application number CN202020712765.9 discloses a water-saving drip irrigation device, including a drip tube with a hollow interior. A water inlet pipe connected to the inside of the drip tube is located on its side. A diverter column is connected to the outside, and multiple radial water inlets are arranged on the side wall of the diverter column. A flow control plug is correspondingly provided on the diverter column, comprising a handle and a cylinder. This water-saving drip irrigation device, through the combined use of the drip tube and the diverter column, with equally spaced water inlets on the diverter column and the flow control plug working in conjunction with the diverter column, controls the number of water inlets, thereby adjusting the water flow rate of the drip tube and achieving water saving. It can be manually adjusted according to different plant types, is simple to operate, and has low cost.

[0004] However, the internal thread of the diversion column of this device is connected to the external thread of the cylinder. Agricultural irrigation water usually contains impurities such as mud, sand and minerals. These impurities are easy to get stuck at the thread, affecting the up and down movement of the cylinder and making cleaning extremely difficult. In addition, there is no sealing between the threads, which will cause some water to seep out from the gaps, resulting in water waste and violating the original intention of water saving in drip irrigation technology. Therefore, an agricultural water-saving drip irrigation device is proposed. Utility Model Content

[0005] The main purpose of this invention is to provide a water-saving drip irrigation device for agriculture, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An agricultural water-saving drip irrigation device includes a sealing pipe, which is movably installed inside a diversion column. A rubber layer is sleeved on the outside of the sealing pipe, and the outside of the rubber layer is tightly fitted to the inside of the diversion column.

[0008] The top end of the sealing tube is rotatably connected to the bottom end of the threaded tube, the threaded tube is threadedly connected to the top end of the heightening seat, and the heightening seat is fixedly installed on the top end of the dropper tube.

[0009] By adopting the above technical solution, a dynamic seal is formed between the rubber layer on the outside of the sealing pipe and the smooth inner wall of the diversion column. This design fundamentally avoids the problem of adjustment failure caused by mud, sand, and mineral impurities in the irrigation water getting stuck in the threads. The adjustment process is smoother and more reliable, and the sealing performance is excellent. It completely eliminates the phenomenon of water leakage from the adjustment gap, truly achieving zero leakage and significant water-saving effect.

[0010] Specifically, the diversion column is located inside the dropper tube, and the side wall of the diversion column is provided with water inlet holes, which are provided in multiple places.

[0011] By adopting the above technical solution, irrigation water enters the drip irrigation tube and then enters its interior through multiple water inlets on the side wall of the diversion column. By moving the sealing pipe up and down, the rubber layer on its outer wall gradually blocks or exposes the water inlets at different heights, thereby changing the effective channel area for water to enter the diversion column and realizing the step-by-step adjustment of the water inflow.

[0012] Specifically, a bearing is fitted onto the outer side of the bottom end of the threaded tube, and the bearing is fixedly installed inside the sealing tube.

[0013] By adopting the above technical solution, when the threaded tube is rotated, the bearing effectively converts the rotational motion of the threaded tube into the pure linear motion of the sealing tube, thus preventing the sealing tube from rotating along with the threaded tube.

[0014] Specifically, the outside of the height-increasing seat is provided with an observation window, and the outside of the rubber layer is provided with a scale ring, which has multiple scale rings.

[0015] By adopting the above technical solution, users can directly observe the movement of the internal sealing pipe and the scale ring on the outside of the rubber layer through the observation window on the riser. The scale rings at different heights correspond to different numbers of water inlet holes being opened. Users can accurately and intuitively judge the current flow regulation status according to the scale indication to achieve quantitative control.

[0016] Specifically, the bottom end of the diverting column is fixedly connected to the top end of the dropper head, and the diverting column is in communication with the inside of the dropper head.

[0017] By adopting the above technical solution, the water that enters the diversion column after being regulated by the inlet hole will flow directly downwards into the drip head connected to it, and finally flow out evenly in the form of drips from the drip head, thus completing the precise irrigation of crops.

[0018] Specifically, a water inlet pipe is fixedly connected to one side of the dropper tube, and the inside of the dropper tube is connected to the inside of the water inlet pipe.

[0019] By adopting the above technical solution, irrigation water is input through the inlet pipe and enters the internal cavity of the drip tube, providing a water source for the entire drip irrigation system; after the water flow is distributed inside the drip tube, it enters the next process through the inlet hole on the diversion column.

[0020] The beneficial effects of this utility model are:

[0021] The agricultural water-saving drip irrigation device described in this utility model uses a rubber layer on the outside of the sealing pipe to form a dynamic seal with the smooth inner wall of the diversion column. This design fundamentally avoids the problem of adjustment failure caused by mud, sand, and mineral impurities in the irrigation water getting stuck in the threads. The adjustment process is smoother and more reliable, and the sealing performance is excellent, completely eliminating the phenomenon of water leakage from the adjustment gaps. It truly achieves zero leakage and has a significant water-saving effect. Attached Figure Description

[0030] In use, by rotating the threaded tube 1, the threaded engagement between it and the riser seat 2 drives the sealing tube 8 to move vertically inside the diverter column 9. The rubber layer 11 on the outside of the sealing tube 8 always keeps in close contact with the inner wall of the diverter column 9, forming a dynamic seal to ensure no leakage during adjustment, while providing the necessary sealing and guiding function for the up and down movement of the sealing tube 8.

[0031] This utility model also includes that the diversion column 9 is disposed inside the dropper tube 4, and the side wall of the diversion column 9 is provided with a water inlet hole 10, and the water inlet hole 10 is provided in multiple places.

[0032] When in use, irrigation water enters the drip tube 4 and then enters its interior through multiple water inlet holes 10 on the side wall of the diversion column 9. By moving the sealing pipe 8 up and down, the rubber layer 11 on its outer wall gradually blocks or exposes the water inlet holes 10 at different heights, thereby changing the effective channel area for water to enter the diversion column 9 and realizing the step-by-step adjustment of the water inflow.

[0033] The present invention also includes a bearing 7 sleeved on the outer side of the bottom end of the threaded tube 1, and the bearing 7 is fixedly installed inside the sealing tube 8.

[0034] When in use, when the threaded tube 1 is rotated, the bearing 7 effectively converts the rotational motion of the threaded tube 1 into the pure linear motion of the sealing tube 8, thus preventing the sealing tube 8 from rotating along with the threaded tube 1.

[0035] The present invention also includes an observation window 3 on the outer side of the height-increasing seat 2, and a scale ring 12 on the outer side of the rubber layer 11, wherein the scale ring 12 has multiple locations.

[0036] During use, the user can directly observe the movement of the internal sealing pipe 8 and the scale ring 12 on the outside of the rubber layer 11 through the observation window 3 on the riser 2; the scale ring 12 at different heights corresponds to different numbers of water inlet holes 10 open, and the user can accurately and intuitively judge the current flow regulation status according to the scale indication to achieve quantitative control.

[0037] The present invention also includes that the bottom end of the diverting column 9 is fixedly connected to the top end of the dropper head 5, and the diverting column 9 is in communication with the interior of the dropper head 5.

[0038] When in use, the water that enters the diversion column 9 after being regulated by the water inlet 10 will flow directly downwards into the drip head 5 connected to it, and finally flow out evenly in the form of drips from the drip head 5 to complete the precise irrigation of crops.

[0041] In use, irrigation water is fed into the dripper tube 4 through the inlet pipe 6. The sealing tube 8 at its bottom is driven to move vertically inside the diversion column 9 by rotating the threaded tube 1. The rubber layer 11 on the outer wall of the sealing tube 8 is always in close contact with the inner wall of the diversion column 9 to form a dynamic seal. As the sealing tube 8 moves up and down, its rubber layer 11 will block or expose different numbers of water inlet holes 10 on the side wall of the diversion column 9. The water flow rate entering the diversion column 9 can be precisely adjusted by changing the effective flow area of ​​the water inlet holes 10. The adjusted water flow finally flows out evenly in the form of water droplets through the dripper head 5, realizing precise irrigation of the crop root zone. The user can view the position of the inside of the heightening seat 2 and the scale ring 12 through the observation window 3, and accurately judge the position of the sealing tube 8 according to the scale ring 12, thereby accurately adjusting the number of water inlet holes 10 to achieve precise control of different flow rates.
