Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology, and in particular to an anti-clogging vortex irrigation device for grape drip irrigation. Background Technology

[0002] In drip irrigation systems for grape cultivation, clogging of the drip emitters is a common problem. Existing equipment typically uses a single filter structure, which is insufficient to handle impurities of different sizes, leading to easy clogging of the drip holes. This affects the stability of water flow, causing uneven irrigation and impacting crop growth. During maintenance, disassembly is inconvenient, increasing labor costs. Although some emitters attempt to optimize the water flow path, there is a lack of effective mechanisms to maintain uniform water flow, resulting in a shorter equipment lifespan. These problems increase the frequency and cost of maintenance in agricultural production. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as easy clogging of drip irrigation holes, inconvenient disassembly increasing labor costs, and the lack of effective mechanisms to maintain uniform water flow despite attempts to optimize water flow paths. Therefore, this invention proposes an anti-clogging vortex-type drip irrigation device for grapes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A clogging-resistant vortex-type irrigation device for grape drip irrigation includes a dripper, a drip hole for drip irrigation at the bottom of the dripper, a water inlet for water intake at the top of the dripper, a vortex mechanism for facilitating drip irrigation inside the dripper, and a filter assembly for filtering the drip irrigation water.

[0006] In one possible design, the vortex mechanism includes four connecting blocks, an inner ring, a connecting rod, a water outlet pipe, an impeller, and a rotating column. The top of the impeller is fixedly connected to the rotating column, and the top of the rotating column is rotatably connected to the bottom center of the connecting rod. The two ends of the connecting rod are respectively fixedly connected to the inner walls of the same inner ring on both sides. The four sides of the inner ring are respectively fixedly connected to one side of the four connecting blocks. The other side of each of the four connecting blocks is fixedly connected to the inner wall of the same dripper. The water outlet pipe is fixedly installed on the top inner wall of the dripper and communicates with the water inlet hole. The water outlet pipe is inclined and located above the blades of the impeller.

[0007] In one possible design, the filter assembly includes a first filter, a second filter, and a filter chamber. The filter chamber is located directly above the dripper. The first filter and the second filter are fixedly mounted on the inner wall of the filter chamber in sequence. The filter holes of the first filter are larger than those of the second filter, and the first filter is tapered.

[0008] In one possible design, the top of the dripper is fixedly connected to a connecting pipe three, the outer side of the top of the connecting pipe three is provided with a threaded groove two, the bottom of the filter chamber is fixedly connected to a connecting pipe two, the inner wall of the connecting pipe two is provided with a threaded groove that matches the threaded groove two, and the connecting pipe two and the connecting pipe three are threadedly connected.

[0009] In one possible design, the connecting pipe three is provided with a sealing ring for sealing.

[0010] In one possible design, the top of the filter chamber is fixedly provided with a connecting pipe for connecting to an external pipeline, and the outer side of the connecting pipe is provided with a threaded groove for easy connection.

[0011] In one possible design, the dripper is shaped like a cone to facilitate accelerating the water flow.

[0012] In this application, when the anti-clogging vortex-type water emitter is working, external water supply enters the filter chamber through connecting pipe one. The double-layer filter screen inside the filter chamber plays its role. The conical stainless steel filter screen one intercepts large particles of impurities such as mud and sand, while the flat nylon filter screen two further filters fine particles, achieving gradient filtration. The filtered water flows through connecting pipe three and enters the outlet pipe from the water inlet at the top of the dripper. The outlet of the water pipe is directly above the impeller blades. The water flow impacts the impeller tangentially, driving the impeller to rotate at high speed and forming a vortex. The inner wall of the conical dripper constrains the water flow, causing the vortex to spiral downwards along the wall and finally be discharged from the drip irrigation hole at the bottom of the dripper, thus achieving irrigation. When the filter screen is clogged, connecting pipe two and connecting pipe three are rotated and disassembled to remove the filter chamber for cleaning or replacement of the filter screen.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, the double-layer filter structure can effectively intercept impurities of different particle sizes, reducing the risk of drip irrigation hole clogging. The filter chamber and the dripper are detachably connected, facilitating regular replacement or cleaning of the filter chamber and reducing maintenance costs. The conical dripper structure, combined with the vortex formed by the impeller, enables water to flow evenly and stably, improving irrigation uniformity and benefiting crop growth. At the same time, this design can extend the service life of the irrigation device and reduce the frequency of replacement due to clogging, bringing convenience and economic benefits to agricultural production.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In one embodiment: Refer to Figures 1-4 A clog-resistant vortex-type water emitter includes a dripper 6, which has a conical structure. The top of the dripper has a water inlet hole 11 and is connected to a filter chamber 3 via a connecting pipe 3 5. The outer wall of the connecting pipe 3 5 has a threaded groove 2 10, which matches the threaded groove on the inner wall of the connecting pipe 2 4 at the bottom of the filter chamber 3 to achieve a detachable connection, facilitating the periodic replacement of the filter chamber 3. To ensure sealing, a rubber sealing ring 9 is embedded on the contact surface between the connecting pipe 3 5 and the connecting pipe 2 4 to prevent leakage. The top of the filter chamber 3 is connected to an external water supply pipe via a connecting pipe 1. The outer wall of the connecting pipe 1 1 has a threaded groove 2 for quick installation.

[0022] The inner ring 13 is fixed to the inner wall of the dripper 6 by four connecting blocks 15 to form a support frame. The two ends of the connecting rod 14 are welded to the inner wall of the inner ring 13, and the center is rotatably connected to the rotating column 17 through a bearing. The impeller 16 is fixed to the bottom of the rotating column 17. The water outlet pipe 12 is inclinedly welded to the inner wall of the top of the dripper 6, and its outlet is directly above the blades of the impeller 16. After the water flows through the water inlet hole 11 into the water outlet pipe 12, it impacts the blades of the impeller 16 tangentially, driving the impeller 16 to rotate at high speed and forming a vortex. The inner wall of the conical dripper 6 further constrains the water flow, so that the vortex spirals downward along the wall and is finally discharged through the bottom drip hole.

[0023] This application can be used in the field of grape drip irrigation, or in other fields applicable to this application.

[0024] In another embodiment: Reference Figures 1-4 A clog-resistant vortex irrigation system for grape drip irrigation, comprising:

[0025] The filter assembly adopts a double-layer filter structure. Filter 7 is a conical stainless steel mesh with a filtration aperture of 0.5mm, used to intercept large particles such as mud and sand. Filter 8 is a flat nylon mesh with a filtration aperture of 0.2mm, which further filters fine particles. The two filter layers are fixed to the inner wall of the filter chamber 3 by a slot to form a gradient filtration. The conical design of filter 7 can expand the filtration area and reduce the risk of clogging. When the filter is clogged, the filter chamber 3 can be removed for cleaning or replacement by rotating and disassembling connecting pipe 2 4 and connecting pipe 3 5.
