Description

Technical Field

[0001] This utility model relates to the field of water-saving irrigation devices, and in particular to a high-clogging, low-flow-rate embedded dripper. Background Technology

[0002] Drip irrigation offers greater water savings and yield increases compared to other irrigation technologies. Its core product is the drip irrigation tape, and the dripper is a crucial component of the tape. Its function is to dissipate turbulent energy; when pressurized water enters the dripper, it is dissipated by the dripper, resulting in a stable and uniform low-flow rate that drips into the soil. A drawback of existing embedded dripper technology is that after the drip irrigation tape wraps around the embedded patch, the low flow rate and shallow flow channel of the embedded patch make the outlet of the flow channel easily covered by the inner surface of the drip irrigation tape, causing blockage and affecting the drip irrigation flow rate.

[0003] Based on this, the present invention designs a highly resistant, low-flow-rate embedded patch dripper to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a highly resistant, low-flow-rate embedded drip tip, which solves the problem that low-flow-rate drip tips in the prior art are more prone to clogging.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A high-anti-clogging, low-flow-rate embedded dripper includes a dripper body, characterized in that: a flow channel structure is formed on the upper surface of the dripper body, one end of the flow channel structure is connected to a guide groove, a plurality of water inlet holes are formed on the guide groove, the other end of the flow channel structure is connected to a water collection trough, and a strip-shaped support block is vertically provided in the water collection trough at the connection of the flow channel structure; a plurality of grids are vertically provided on the lower surface of the dripper body, and the water inlet holes are located between two adjacent grids.

[0006] Furthermore, the flow channel structure is wavy or serrated.

[0007] Furthermore, there are at least 14 water inlets.

[0008] Furthermore, the upper surface of the dripper body is arc-shaped.

[0009] This utility model has the following beneficial effects: The strip support block designed in this invention can effectively prevent structural deformation that may be caused when the water collection tank is tightly fitted to the pipe wall, while ensuring that the dripping rate is not affected. It is suitable for various small-flow embedded patch drippers. Attached Figure Description

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0012] The attached diagram lists the components represented by each number as follows: 1. Drip head body; 2. Water inlet hole; 3. Grille; 4. Guide channel; 5. Flow channel structure; 6. Strip support block; 7. Water collection tank. Detailed Implementation

[0013] 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. It should be understood that the terms "upper", "middle", "outer", "inner", "lower" etc., which indicate orientation or positional relationship, are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0014] The attached figures illustrate specific embodiments of this utility model, such as... Figures 1-2As shown, this utility model is a high-anti-clogging, low-flow-rate embedded dripper, including a dripper body 1. The upper surface of the dripper body 1 is arc-shaped to facilitate fitting with the drip irrigation tape wall. A flow channel structure 5 is formed on the upper surface of the dripper body 1. The flow channel structure 5 is wavy, toothed, or can be other shapes. When water flows through the flow channel structure, the turning points of the flow channel structure can create resistance to the water flow, slowing down the water flow velocity and controlling the drip rate. One end of the flow channel structure 5 is connected to a guide groove 4. Several water inlet holes 2 are formed on the guide groove 4. The water inlet holes 2 penetrate the upper and lower surfaces of the dripper body 1 to intercept large particulate impurities in the water and prevent them from clogging the dripper. In this embodiment, there are 14 water inlet holes 2. Any one of the water inlet holes 2 can ensure the flow supply of the dripper body 1 when used alone. The other end of the flow channel structure 5 is connected to the water collection tank 7. When in use, a hole is made in the drip irrigation tape at the corresponding position above the water collection tank 7. The water flows through the water inlet hole 2 and enters the guide channel 4, the flow channel structure 5, and the water collection tank 7 in sequence, and finally drips out from the hole in the drip irrigation tape to achieve the effect of small flow drip irrigation. Since this embodiment uses a 0.35L / h dripper, which is a low-flow dripper, the grooves in the flow channel structure 5 and other grooves on the upper surface of the dripper body 1 have a small depth. Even a slight indentation in the outer wall of the drip irrigation tape could block the connection between the flow channel structure 5 and the water collection tank 7, resulting in reduced flow. To avoid this, this invention provides a vertically oriented strip support block 6 at the connection between the water collection tank 7 and the flow channel structure 5. The strip support block 6 has a certain gap at the intersection of the flow channel structure 5 and the water collection tank 7. During use, the strip support block 6 can support the outer wall of the drip irrigation tape, maintaining the overall structure of the dripper without deformation and preventing the drip irrigation tape from completely covering the upper surface of the dripper body 1 during production shrinkage, thus avoiding flow channel blockage. The lower surface of the dripper body 1 is vertically provided with several grids 3, separating adjacent water inlets 2. The grids 3 ensure that each water inlet 2 operates independently, preventing impurities from accumulating and migrating at a particular water inlet 2, thus affecting adjacent water inlets 2 that are functioning normally. In this embodiment, the grille 3 can also block particles of a specific shape, such as sheet-like particles. When sheet-like particles cover the water inlet 2, the grille 3 can support the sheet-like particles and will not affect the water intake effect of the water inlet 2 below.

[0015] Another embodiment of this utility model is a small flow dripper with a flow rate of 0.75L / h. The difference between this and the small flow dripper with a flow rate of 0.35L / h in embodiment 1 is that the flow channel structure 5 and the depth of the water collection tank 7 are different.

[0016] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to specific implementation methods.
