Anti-negative pressure self-cleaning drip irrigation tape

Abstract

This utility model relates to the field of drip irrigation tape technology, and more particularly to a self-cleaning drip irrigation tape with anti-negative pressure. The self-cleaning drip irrigation tape with anti-negative pressure includes a drip irrigation tape body, with mounting holes at the bottom of the tape body. A drip tray is fixedly installed in each mounting hole, and the drip tray has drip holes. A rotating disk is rotatably connected to the drip tray, and the rotating disk has drop holes corresponding to the drip holes. An impeller is installed on the rotating disk, and a cleaning pipe is connected to the drip irrigation tape body. The self-cleaning drip irrigation tape with anti-negative pressure provided by this utility model uses intermittent drip irrigation instead of continuous drip irrigation, which helps reduce soil surface moisture evaporation. Furthermore, the intermittent drip irrigation helps balance the pressure inside the pipe, thus preventing negative pressure. Opening the valve allows the angled nozzles to flush the drip irrigation tape body below, effectively removing accumulated impurities. This eliminates the need for frequent manual cleaning, reducing labor intensity and improving irrigation efficiency.

Description

Technical Field

[0001] This utility model relates to the field of drip irrigation tape technology, and in particular to a self-cleaning drip irrigation tape with anti-negative pressure. Background Technology

[0002] In the field of drip irrigation tape technology, traditional drip irrigation tape has some problems during use. On the one hand, when the drip irrigation system stops working, negative pressure can easily be generated inside the pipe, which can cause impurities such as soil to be sucked into the drip irrigation tape, thereby clogging the drip holes and affecting the normal operation of drip irrigation. On the other hand, after long-term use, impurities may accumulate inside the drip irrigation tape, and traditional drip irrigation tape itself lacks an effective cleaning mechanism, requiring manual cleaning, which not only increases labor intensity but also affects irrigation efficiency.

[0003] Therefore, it is necessary to provide a new anti-negative pressure self-cleaning drip irrigation tape to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a self-cleaning drip irrigation tape with anti-negative pressure.

[0005] The anti-negative pressure self-cleaning drip irrigation tape provided by this utility model includes a drip irrigation tape body. The bottom of the drip irrigation tape body is provided with a number of equally spaced mounting holes, and a drip tray is fixedly installed in each mounting hole. The drip tray is provided with a number of fan-shaped drip holes, and a rotating disk is mounted on the drip tray. The rotating disk is provided with drop holes that correspond one-to-one with the drip holes.

[0006] An impeller is mounted on the rotating disk;

[0007] The drip irrigation tape is also connected to a cleaning pipe, and the cleaning pipe is equipped with an angled nozzle.

[0008] Preferably, a rotating rod is fixedly installed on the rotating disk, and the impeller is fixedly sleeved on the rotating rod.

[0009] Preferably, the cleaning tube is located above the drip irrigation tape, and the cleaning tube has several evenly distributed oblique nozzles on both sides near the bottom of the tube.

[0010] Preferably, a valve is fixedly installed on the cleaning pipe.

[0011] Preferably, an annular mounting base is fixedly installed on the drip tray, and the inner ring wall of the annular mounting base is provided with a T-shaped groove.

[0012] Preferably, a T-shaped ring with a T-shaped cross-section is fixedly installed on the outer ring wall of the rotating disk, and the T-shaped ring is inserted into the T-shaped groove of the annular mounting seat and rotatably connected to the T-shaped groove.

[0013] Preferably, the drip tray and the rotating tray are in close contact with each other.

[0014] Compared with related technologies, the anti-negative pressure self-cleaning drip irrigation tape provided by this utility model has the following beneficial effects:

[0015] 1. This utility model uses water flow to impact the impeller, thereby driving the rotating disk to rotate. As the rotating disk rotates, the drop holes on the rotating disk periodically align and stagger with the drip holes on the drip tray. When the drop holes and drip holes are aligned, a connecting flow channel is formed; when they are staggered, the flow channel is closed. This periodic opening and closing allows the drip irrigation tape to drip intermittently rather than continuously, which helps reduce soil surface moisture evaporation and improve irrigation efficiency. In particular, the intermittent drip irrigation of this drip irrigation tape helps to balance the pressure inside the pipe and prevents negative pressure.

[0016] 2. This utility model opens the valve to allow water to enter the cleaning pipe, and through the angled nozzles on the cleaning pipe, it washes the drip irrigation tape below, effectively removing impurities accumulated in the drip irrigation tape. It eliminates the need for frequent manual cleaning, reduces labor intensity, and improves irrigation efficiency. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 3This utility model provides a self-cleaning drip irrigation tape with negative pressure prevention, which includes a drip irrigation tape body 1, a drip tray 2, and a rotating tray 3.

[0024] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 3 The drip irrigation tape body 1 has several equally spaced mounting holes 1a at its bottom, and a drip tray 2 is fixedly installed in each mounting hole 1a. The drip tray 2 has multiple fan-shaped drip holes 2a, and a rotating disk 3 is rotatably connected to the drip tray 2. The rotating disk 3 has drop holes 3a that correspond one-to-one with the drip holes 2a. An impeller 4 is installed on the rotating disk 3. Specifically, a rotating rod 41 is fixedly installed on the rotating disk 3, and the impeller 4 is fixedly sleeved on the rotating rod 41.

[0025] It should be noted that when the drip irrigation tape 1 is filled with liquid, the water flow impacts the impeller 4, thereby driving the rotating disk 3 to rotate. As the rotating disk 3 rotates, the liquid drop hole 3a on the rotating disk 3 periodically aligns and offsets with the drip point hole 2a on the drip tray 2. When the liquid drop hole 3a aligns with the drip point hole 2a, a connecting flow channel is formed. When they offset, the flow channel is closed. This periodic opening and closing allows the drip irrigation tape 1 to drip intermittently rather than continuously, which helps reduce soil surface moisture evaporation and improve irrigation efficiency. In particular, the intermittent drip irrigation of this drip irrigation tape 1 helps to balance the pressure inside the pipe and plays a role in preventing negative pressure.

[0026] Furthermore, the dripping plate 2 and the rotating plate 3 are fitted together. An annular mounting base 21 is fixedly installed on the dripping plate 2, and a T-shaped groove is opened on the inner ring wall of the annular mounting base 21. A T-shaped ring 31 with a T-shaped cross-section is fixedly installed on the outer ring wall of the rotating plate 3. The T-shaped ring 31 is inserted into the T-shaped groove opened on the annular mounting base 21 and is rotatably connected to the T-shaped groove, so that the rotating plate 3 can rotate stably along the dripping plate 2.

[0027] In the embodiments of this utility model, please refer to Figure 1 The drip irrigation tape body 1 is also connected to a cleaning pipe 5, and the cleaning pipe 5 is provided with an angled nozzle 5a. The cleaning pipe 5 is located above the drip irrigation tape body 1, and several evenly distributed angled nozzles 5a are opened on both sides of the cleaning pipe 5 near the bottom of the pipe body. A valve 51 is fixedly installed on the cleaning pipe 5.

[0028] It should be noted that opening valve 51 allows water to enter the cleaning pipe 5, and through the angled nozzle 5a on the cleaning pipe 5, it washes the drip irrigation tape 1 below, which can effectively remove the impurities accumulated in the drip irrigation tape. This eliminates the need for frequent manual cleaning, reduces labor intensity, and improves irrigation efficiency.

[0029] It is worth noting that a filter structure is installed at the inlet of the drip irrigation tape 1 to filter the water entering the drip irrigation tape 1, reduce the content of impurities in the water, and reduce the impact of impurities on the impeller, drip plate 2 and rotating plate 3.

[0030] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
