Description

Technical Field

[0001] This utility model relates to the technical field of drip irrigation pipes, and in particular to a drip irrigation pipe with a flexibly detachable drip head. Background Technology

[0002] Drip irrigation pipes are the core irrigation equipment of drip irrigation systems. They precisely deliver water and nutrients to the soil around the roots of crops through low-pressure pipes and emitters on the capillary tubes. They are mainly used in field crops, orchards, greenhouses, and landscaping projects. They are mainly divided into two types of water outlets: pressure-compensated and non-pressure-compensated, and two structural types: embedded and inter-pipe.

[0003] As a core component of water-saving irrigation systems, drip irrigation heads have evolved into mainstream product types, including pressure-compensated and eight-hole adjustable types. The selection should be based on flow parameters and anti-clogging performance.

[0004] Chinese patent document CN108834835A discloses a dripper for drip irrigation, including a housing, a piston slidably connected within the housing, and a rear cover. The piston includes a first piston portion, a second piston portion, and a connecting rod portion connecting the first piston portion and the second piston portion. The area of ​​the outer end of the first piston portion is S1, and the area of ​​the outer end of the second piston portion is S2, wherein S1 and S2 satisfy: S1 < S2. The housing has a first piston cavity that matches the shape of the first piston portion, and a second piston cavity that matches the shape of the second piston portion. The housing has a channel connecting the left end of the first piston cavity and the right end of the second piston cavity. The sidewall of the first piston cavity is provided with a plurality of drip outlets that penetrate the housing at equal intervals along the movement direction of the first piston portion. The housing also has a spring that drives the first piston portion to move to the right side of the first piston cavity, thereby opening the drip outlets. Regardless of the pressure of the water inside the dripper, the flow rate of water dripping from the dripper can always remain relatively constant.

[0005] The aforementioned patent document states that regardless of changes in the internal water pressure, the flow rate of water dripping from the dripper can always remain relatively constant during implementation. However, it does not allow for convenient disassembly and assembly of the dripper head, resulting in a significant amount of time and effort required for replacement or maintenance, which affects the effectiveness of the dripper head.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A drip irrigation tube with a flexibly detachable drip head includes a drip irrigation tube one. A plurality of diversion components are fixedly connected at intervals on the lower part of the outer surface of the drip irrigation tube one. Each of the plurality of diversion components is threadedly connected to a connecting mechanism.

[0011] Preferably, the filtering mechanism includes a loading frame, a filter screen is fixedly installed in the middle of the inner cavity of the loading frame, and the outer surface of the loading frame is movably connected to the inner cavity of the corresponding connecting sleeve.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 As shown, a drip irrigation tube with a flexibly detachable drip head includes a drip irrigation tube 1. Several diversion components 2 are fixedly connected at intervals to the lower outer surface of the drip irrigation tube 1, enabling the diversion of water within the drip irrigation tube 1. Each diversion component 2 is internally threaded with a connecting mechanism 3, facilitating installation and disassembly. Each connecting mechanism 3 has a movably connected filter mechanism 4 on its lower inner side, intercepting and filtering particulate impurities in the water. Each connecting mechanism 3 has a detachably connected bearing mechanism 5 on its lower outer side, supporting several positioning mechanisms 6. Each bearing mechanism 5 has a fixedly connected positioning mechanism 6 in a circular array, allowing the bearing mechanism 5 to be locked and secured to the lower outer side of the corresponding connecting mechanism 3. Each bearing mechanism 5 has a fixedly connected drip head 7 on its lower outer side.

[0024] To achieve the goal of diverting water from the inner cavity of drip irrigation tube 1, please refer to... Figure 2 The diversion component 2 includes a limiting plate 21, and a diversion pipe 22 is fixedly connected to the lower part of the outer surface of the limiting plate 21, which can realize the function of connecting the corresponding external threaded pipe 31.

[0025] For ease of installation and removal with the corresponding splitter component 2, please refer to... Figure 3 The connecting mechanism 3 includes an external threaded tube 31. A connecting sleeve 32 is fixedly connected to the lower end of the outer surface of the external threaded tube 31, which can accommodate the loading frame 41. Several positioning holes 33 are arranged in an annular array on the side wall of the outer surface of the connecting sleeve 32. The outer surface of the external threaded tube 31 is threadedly connected to the inner surface of the corresponding diversion tube 22.

[0026] To achieve the goal of intercepting and filtering particulate impurities in water, please refer to... Figure 3 The filtration mechanism 4 includes a loading frame 41, and a filter screen 42 is installed and fixed in the middle of the inner cavity of the loading frame 41. It can intercept and filter particulate impurities contained in the water flowing into the inner cavity of the external threaded pipe 31. The outer surface of the loading frame 41 is movably connected to the inner cavity of the corresponding connecting sleeve 32.

[0027] To achieve the purpose of supporting several positioning mechanisms 6, refer to... Figure 3 The bearing mechanism 5 includes a bearing housing 51. The inner wall of the bearing housing 51 has a plurality of rectangular cavities 52 arranged in a ring array. A sealing gasket 53 is installed and fixed in the middle of the bottom wall of the inner cavity of the bearing housing 51, which can seal the lower end of the outer surface of the connecting housing 32 with the opening end of the bottom wall of the inner cavity of the bearing housing 51. The inner surface of the bearing housing 51 is slidably connected to the corresponding outer surface of the connecting housing 32.

[0028] To facilitate locking the bearing mechanism 5 to the lower side of the corresponding connecting mechanism 3, refer to... Figure 4 The positioning mechanism 6 includes a U-shaped plate 61, a convex spring sheet 62 fixedly connected to the middle of the inner cavity of the U-shaped plate 61, a hemispherical block 63 fixedly connected to the middle of the outer surface of the convex spring sheet 62, and the outer surface of the U-shaped plate 61 is fixedly connected to the inner cavity of the corresponding rectangular cavity 52.

[0029] When it is necessary to disassemble the drip head 7, pull down the bearing sleeve 51 so that several hemispherical blocks 63 slide down along the outer surface sidewall of the connecting sleeve 32. The hemispherical blocks 63 will squeeze the corresponding convex spring sheet 62. At this time, the contracted convex spring sheet 62 allows the hemispherical blocks 63 to be dislodged from the inner cavity of the corresponding positioning hole 33. Thus, the bearing sleeve 51 can be successfully disassembled from the outer surface of the corresponding connecting sleeve 32.

[0030] The working principle of this utility model is as follows: When the water in the inner cavity of the drip irrigation tube 1 is diverted through the diversion tube 22 and enters the external threaded tube 31, it then flows into the loading frame 41 through the external threaded tube 31. At this time, the filter screen 42 can intercept and filter particulate impurities in the water. Meanwhile, the bearing sleeve 51 is fitted on the outside of the connecting sleeve 32. At the same time, the convex spring plate 62 on the U-shaped plate 61 will push the hemispherical block 63 into the positioning hole 33 of the connecting sleeve 32, thereby locking the bearing sleeve 51 and the connecting sleeve 32 tightly. Then, drip irrigation can be performed through the drip head 7 at the lower end of the bearing sleeve 51. When disassembling, pull down the bearing sleeve 51, and several hemispherical blocks 63 will squeeze the corresponding convex spring plate 62 to contract. At this time, several hemispherical blocks 63 will slide out from the corresponding positioning hole 33 until disassembly is completed.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
