Description

Technical Field

[0001] The utility model belongs to the field of agricultural water-saving drip irrigation equipment, and particularly relates to a water-saving irrigation non-blocking water seepage buckle. Background Art

[0002] Drip irrigation is an irrigation method that, according to the water requirements of crops, through a pipeline system and emitters installed on the lateral pipes, evenly and slowly drips water and the water and nutrients required by the crops into the root zone soil of the crops. The blockage of the emitter is the most main problem in the current application of drip irrigation. In severe cases, it will cause the entire system to fail to work properly or even be scrapped. The causes of blockage can be physical factors, biological factors or chemical factors, such as sediment, organic matter or microorganisms, and chemical precipitates in water.

[0003] The patent with the authorization announcement number CN215602427U provides an inlaid flat emitter, which has the abilities of anti-blocking, anti-rolling, anti-fold and anti-stretching, and has a long service life. Without changing the original size of the emitter, it adopts a turbulent flow channel with an overall U shape, increases the length of the flow channel, and further improves the dripping uniformity and turbulent effect. This emitter is used for drip irrigation by bonding it to the inner wall of the PE water pipe. Therefore, it cannot be fixed on the outside of the PE water pipe, and there is a problem of inconvenient disassembly and replacement. Content of the Utility Model

[0004] The utility model aims at the defects or deficiencies existing in the prior art in the above background art, and provides a water-saving irrigation non-blocking water seepage buckle that is buckled on the outside of the drip irrigation lateral pipe. This water seepage buckle has the ability of anti-blocking, and is convenient, fast for disassembly and replacement.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The water-saving irrigation non-blocking water seepage buckle includes a buckle body for buckling on the outside of the drip irrigation lateral pipe. The buckle body is a circular pipe axially provided with a through notch. A hollow protrusion is arranged in the middle of the buckle body. Axially arranged water guide grooves are formed on the inner side wall of the buckle body. One end of the water guide groove is communicated with the hollow protrusion, and the other end is communicated with the water outlet grid channel. It is installed on the outside of the drip irrigation lateral pipe by clamping the buckle body, and the water outlet holes opened on the drip irrigation lateral pipe are opposite to the hollow protrusion.

[0007] Further, there are two of the water guide grooves, and they are symmetrically arranged on both sides of the hollow protrusion.

[0008] Further, the central angle of the cross section of the notch is less than 180 degrees.

[0009] Preferably, the central angle of the cross section of the notch is 90 degrees.

[0010] Furthermore, the water outlet grid channel is of a staggered structure. By setting the water outlet channel of the staggered structure, the water outlet resistance is increased to reduce the water pressure. Even if it is blocked, water can seep through the pores of the soil by the osmosis of water, without affecting the water outlet.

[0011] Furthermore, the water guide groove is communicated with the water outlet grid channel through a zigzag water guide channel. By setting the zigzag water guide channel, the flow resistance is increased to reduce the water pressure and maintain the uniformity of the water output.

[0012] Compared with the prior art, the beneficial technical effects of the present utility model are as follows: The water-saving irrigation non-blocking water seepage buckle of the present utility model is installed on the outer side of the drip irrigation branch pipe, and has the capabilities of uniform dripping and anti-blocking, and is convenient and fast to install, disassemble and replace.

[0017] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below through preferred embodiments.

[0018] Please refer to the attached Figure 1-2 , the water-saving irrigation non-blocking water seepage buckle provided in this embodiment includes a buckle body 1 for buckling on the outer side of the PE drip irrigation branch pipe 7. The buckle body 1 is a circular pipe axially provided with a through notch 2. A hollow protrusion 3 is arranged in the middle of the buckle body 1. A water guide groove 4 is axially opened on the inner side wall of the buckle body 1. One end of the water guide groove 4 is communicated with the hollow protrusion 3, and the other end is communicated with the water outlet grid channel 6.

[0019] In this embodiment, the drip irrigation branch pipe 7 is a PE pipe with a diameter of 16 mm. Small holes with a diameter of 1.5 - 2.5 mm are drilled at equal intervals on the drip irrigation branch pipe 7 to form a stable hole structure as the water outlet holes 8; the buckle body 1 is made of PE material.

[0020] Specifically, there are two water guide grooves 4, which are symmetrically arranged on both sides of the hollow protrusion 3. The central angle of the cross-section of the notch 2 is 90 degrees, that is, 1 / 4 of a circle. The water outlet grille channel 6 is of a staggered butted structure. The water guide groove 4 is communicated with the water outlet grille channel 6 through a zigzag water guide channel 5.

[0021] In this embodiment, the hollow protrusion 3 forms a cavity to decompress the pressurized water flowing out of the water outlet holes 8 of the drip irrigation branch pipe 7. The zigzag water guide channel 5 increases the flow resistance to further reduce the water pressure and maintain the uniformity of the water output. The water outlet grille channel 6 with a staggered butted structure also has the effect of increasing the water outlet resistance, and even if it is blocked, it does not affect the water outlet.

[0022] Please refer to the attached Figure 3 As shown in the figure, the installation and use method of the water-saving irrigation non-blocking seepage buckle of the present utility model and the drip irrigation branch pipe 7: Fold the drip irrigation branch pipe 7, align the notch 2 of this seepage buckle with the folding line, and press it hard to install. The buckle body 1 is clamped on the outer side of the PE drip irrigation branch pipe 7, and then align the hollow protrusion 3 with the water outlet hole 8. After alignment, a space is formed by the hollow protrusion 3 at the water outlet hole 8.

[0023] The working principle of the present utility model: When water sprays out from the water outlet holes 8 of the drip irrigation branch pipe 7, a back pressure is formed inside the hollow protrusion 3. After the water pressure is evenly distributed, the water flows out along the water guide groove 4, and successively flows out through the zigzag water guide channel 5 and the water outlet grille channel 6 with a staggered butted structure. Since the water outlet resistance of the water guide channel 5 and the water outlet grille channel 6 is greater than the force of discharging air, a relatively stable pressure is not formed in a single drip irrigation branch pipe 7. Multiple seepage buckles arranged at equal intervals form water output compensation at different positions, achieving the purpose of water-saving irrigation. When this seepage buckle is buckled on the drip irrigation branch pipe 7, the water outlet hole 8 is aligned with the hollow protrusion 3, so that the water outlet hole 8 and the hollow protrusion 3 are connected as a whole to form a hollow cavity. When water flows out from the water outlet hole 8, it flows out normally. When the water supply stops, the water in the drip irrigation branch pipe 7 retracts, and the water outlet hole 8 is completely in contact with the air. Water or fertilizer will not precipitate blockage. As long as the water outlet hole 8 is not blocked, the irrigation operation can be repeated, achieving non-blocking water outlet.

[0024] The above is the preferred embodiment of the present utility model to explain the technical solution of the present utility model. Those skilled in the art can also make routine modifications, equivalent replacements, and improvements within the spirit and principles of the present utility model.
