Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, and in particular to an agricultural irrigation anti-clogging drip irrigation tape and irrigation system. Background Technology

[0002] Ordinary drip irrigation tape consists of a flexible plastic tubular tape with water outlets. Water is forced out of the tape by dripping or spraying through these outlets after the pressure in the main pipeline is reduced. In agricultural irrigation, water is typically drawn from reservoirs or cisterns using pumps. However, the outlets of drip irrigation tape are prone to clogging during use. To address this issue, our company's technical staff has developed an anti-clogging drip irrigation tape and system for agricultural irrigation.

[0003] A search revealed Chinese patent document CN204272663U, published on April 22, 2015, which discloses a drip irrigation tape with a concentric filter. The drip irrigation tape has a hollow cylindrical structure with pores spaced at intervals on its sides for connecting drippers. A cylindrical filter with a pore size of 60-150 mesh is embedded within the hollow cavity of the drip irrigation tape. A support frame is provided on the side of the cylindrical filter, which, through the action of the support frame, holds the cylindrical filter within the hollow cavity of the drip irrigation tape, forming a concentric circle structure. The cylindrical filter is made of one of polyethylene, polypropylene, polyvinylidene fluoride, or polytetrafluoroethylene. Its advantages are: the drip irrigation tape effectively prevents impurities such as mud and sand from clogging the drippers, and it has high economic efficiency and practicality; its disadvantages are: the structure is relatively complex, the operating cost is high, and the support frame is not convenient for connecting and fixing to the drip irrigation tape and filter.

[0004] Similarly, Chinese patent document CN204272663U discloses an anti-clogging and easy-to-use drip irrigation pipe, including a capillary tube with drip holes. A filter screen, cylindrical in shape, is fitted onto the inner wall of the capillary tube. A support is arranged in a spiral pattern between the filter screen and the tube wall. Its advantages are that the support is easy to install and effectively prevents the drip holes from clogging. Its disadvantages are that the structure is relatively complex, the cost of use is high, and the spiral arrangement of the support makes it difficult to store the drip irrigation pipe.

[0005] In addition, Chinese patent document CN202907562U also discloses a drip irrigation tape. This drip irrigation tape includes an upper tape body and a lower tape body, with a water pressure reducer installed in the lower tape body. A filter device is also provided between the upper and lower tape bodies, allowing the irrigation water, which has already been filtered before entering the drip irrigation tape, to be filtered again before entering the water pressure reducer. The water, after this second filtration, can then drip out through the water pressure reducer. Its advantages are: because an additional filter layer is added to the drip irrigation tape, various particles such as sediment in the irrigation water can be further filtered before entering the water pressure reducer, reducing the likelihood of micropores in the pressure reducer becoming clogged, extending the service life of the drip irrigation tape, and improving efficiency. Its disadvantages are: the filter cloth is flexible and easily adheres to the labyrinthine flow channels during use. In this case, each labyrinthine flow channel only filters through the filter cloth at the inlet, affecting the filtration effect, and the inlet of the labyrinthine flow channel is prone to clogging. Utility Model Content

[0006] The purpose of this utility model is to provide an agricultural irrigation anti-clogging drip irrigation tape and irrigation system. By installing a filter screen on the inner wall of the tubular tape, the filter screen is elastically supported on the side away from the water outlet. During use, the filter screen will not stick to the water outlet and will not clog the water outlet, thus ensuring the filtration effect.

[0007] To achieve the above objectives, this utility model provides an agricultural irrigation anti-clogging drip irrigation tape, including a tubular tape body with water outlet holes. A filter screen is installed on the inner wall of the tubular tape body on the side of the water outlet holes. The filter screen is the same length as the tubular tape body and is elastically protruded and supported on the side away from the water outlet holes. The filter holes on the filter screen are smaller than the diameter of the water outlet holes.

[0008] The two sides of the filter screen are respectively connected and fixed to the tubular belt.

[0009] The filter screen has extension edges on both sides, which are connected and fixed to the tubular belt.

[0010] The filter screen has an arc-shaped structure.

[0011] The filter screen has a bent structure.

[0012] The tubular strip is closed into a tubular shape through the butt joint.

[0013] The protrusion height L1 of the filter screen is 1 / 3 to 1 / 4 of the diameter L of the tubular strip, and the width L2 of the filter screen is 1.5 to 2.5 times the protrusion height L1.

[0014] The outer wall of the tubular belt is fixedly connected to a baffle at the water outlet. The baffle covers the water outlet, and there is a gap between the baffle and the tubular belt for water to flow out.

[0015] An irrigation system employs the aforementioned agricultural irrigation anti-clogging drip irrigation tape.

[0016] Compared with the prior art, this utility model has the following technical effects:

[0017] 1. This utility model uses a filter screen installed on the inner wall of a tubular belt. The filter screen has elastic protrusions that support the water outlet, preventing it from sticking to the outlet and clogging it during use, thus ensuring effective filtration. Furthermore, it has a simple structure and low operating costs.

[0018] 2. The filter screen of this utility model has a bent structure, which provides better support and facilitates the storage of drip irrigation tape when it is wound into a disc. The filter screen can be folded for storage.

[0019] 3. The tubular belt of this utility model is closed into a tubular shape by the butt joint, which facilitates the welding and installation of filter screens inside the tubular belt.

[0020] 4. The outer wall of the tubular belt of this utility model is fixedly connected with a baffle at the water outlet. The baffle covers the water outlet, and there is a gap between the baffle and the tubular belt for water to flow out. Even if the water pressure is too high, the water will not spray out.

[0028] Tubular belt 10, water outlet 11, connecting edge 12, baffle 13, filter screen 20, extension edge 21. Detailed Implementation

[0029] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0030] Example 1:

[0031] Please see Figure 1-5 An agricultural irrigation anti-clogging drip irrigation tape includes a tubular tape body 10 with water outlet holes 11. A filter screen 20 is installed on the inner wall of the tubular tape body 10 on one side of the water outlet holes 11. The filter screen 20 is the same length as the tubular tape body 10 and is elastically protruded and supported on the side away from the water outlet holes 11. The filter holes on the filter screen 20 are smaller than the diameter of the water outlet holes 11.

[0032] By installing a filter screen 20 on the inner wall of the tubular belt 10, the filter screen 20 is elastically protruded and supported on the side away from the water outlet 11. During use, the filter screen will not stick to the water outlet and will not clog the water outlet, thus ensuring the filtration effect.

[0033] In this embodiment, see Figure 1 The filter screen 20 has an arc-shaped structure.

[0034] When the tubular belt 10 is made of plastic, the filter screen 20, also made of plastic, is heat-fused to the inner wall of the tubular belt 10 on both sides. The plastic filter screen 20 is densely covered with filter holes.

[0035] Furthermore, to improve the strength of the connection, extension edges 21 are provided on both sides of the filter screen 20, and the extension edges 21 are connected and fixed to the tubular belt body 10. After the extension edges 21 are provided, they can be ultrasonically welded to the inner wall of the tubular belt body 10.

[0036] Example 2:

[0037] The difference from Example 1 is that, see [link to example]. Figure 2 The filter screen 20 has a bent structure. The bent structure provides better support and also facilitates the storage of the drip irrigation tape. For storage, please refer to... Figure 5 The filter screen 20 can be folded.

[0038] Example 3:

[0039] Based on Embodiment 1 or Embodiment 2, the tubular belt 10 is closed into a tubular shape via the butt joint 12, facilitating the welding and installation of the filter screen 20 within the tubular belt 10. After welding, the filter screen 20 is then closed into a tubular shape again via the butt joint 12. The butt joint 12 can be made of... Figure 4 The structure in the middle is ultrasonically welded, and the welding can be done by staggered overlay.

[0040] Example 4:

[0041] Based on Example 1, 2, or 3, see [link to example]. Figure 1 The protrusion height L1 of the filter screen 20 is 1 / 3 to 1 / 4 of the diameter L of the tubular belt 10, and the width L2 of the filter screen 20 is 1.5 to 2.5 times the protrusion height L1. This structure ensures the support of the filter screen 20.

[0042] In one embodiment, the diameter L of the tubular belt 10 is 19 mm, the protrusion height L1 of the filter screen 20 is 5 mm, and the width L2 of the filter screen 20 is 10 mm.

[0043] Example 5:

[0044] Based on embodiments 1, 2, 3, or 4, when the water pressure inside the tubular belt 10 is too high, water will spray out from the outlet 11. Since in actual use, the outlet 11 may not be directly facing the ground, the water spraying out cannot irrigate the land directly below. Therefore, see... Figure 1 , 2 A baffle 13 is fixedly connected to the outer wall of the tubular belt 10 at the water outlet 11. The baffle 13 blocks the water outlet 11, and there is a gap between the baffle 13 and the tubular belt 10 for water to flow out. By setting the baffle 13, the water outlet 11 is blocked, so water will not spray out even if the water pressure is too high.

[0045] In this embodiment, the baffle 13 is made of flexible plastic sheet, and the baffle 13 is heat-fused or ultrasonically welded to the tubular belt 10 made of plastic. The baffle 13 can be connected to the left and right sides of the tubular belt 10, or to three sides. That is to say, at least one part must be left unconnected so that water can flow out from the gap between the baffle 13 and the tubular belt 10.

[0046] Example 6:

[0047] An irrigation system employs the aforementioned agricultural irrigation anti-clogging drip irrigation tape.

[0048] The working principle or operation process of this utility model is as follows:

[0049] See Figure 1 , 2 A filter screen 20 is installed on the inner wall of the tubular belt 10. The filter screen 20 is elastically protruded and supported on the side away from the water outlet 11. The filter screen will not stick to the water outlet and will not block the water outlet, thus ensuring the filtration effect.

[0050] When in use, the water supply pipe is inserted into the side of the filter screen 20 inside the tubular belt 10 away from the water outlet 11. The tubular belt 10 can be fixed to the water supply pipe by cable ties or clamps.
