Abstract
Description
Technical Field
[0001] This utility model relates to the field of drip irrigation tape technology, and in particular to a low-flow compensating drip irrigation tape. Background Technology
[0002] Drip irrigation is a precise irrigation method that uses a low-pressure pipeline system to deliver water directly to the field. The water is then dripped evenly and slowly into the soil near the crop root zone through emitters, orifices, or drip tapes installed on the capillary tubes. This keeps the soil in the most developed root zone at a suitable level of moisture, ensuring that the soil's water, fertilizer, air, heat, and microbial activity are always in good condition, creating favorable conditions for high and stable crop yields.
[0003] Traditional drip irrigation tape has the following technical defects in long-term use:
[0004] 1. Defects in impurity management: Existing drip irrigation tapes lack an integrated impurity collection system. Deposits require disassembly and cleaning of the pipe body, which can easily cause pipe wall wear or leakage at joints.
[0005] 2. Water flow diffusion and positioning deviation: Conventional drip irrigation tapes do not have a flow guiding structure at the outlet, so water droplets easily spread along the pipe wall, resulting in local soil over-wetting or irrigation position deviation.
[0006] Therefore, in order to solve the aforementioned problems, we propose a low-flow compensating drip irrigation tape. Utility Model Content
[0007] The purpose of this invention is to address the deficiencies in the existing technology by proposing a low-flow-rate compensating drip irrigation tape.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] A low-flow compensating drip irrigation tape includes a drip irrigation tape body, a pressure compensating dripper fixedly installed on the upper side of the drip irrigation tape body, a collection component fixedly installed on the lower side of the drip irrigation tape body, and a filter screen fixedly installed inside the drip irrigation tape body, the filter screen being located between the pressure compensating dripper and the collection component.
[0010] Furthermore, the collection assembly includes a connecting tube and a collection bottle. The connecting tube is fixedly installed on the lower side of the drip irrigation tape body, and the bottom end of the connecting tube is threadedly connected to the bottle opening of the collection bottle.
[0011] Furthermore, the collection bottle has a transparent structure.
[0012] Furthermore, a flow guide ring is fixedly installed on the outer surface of the drip irrigation tape body, and the flow guide ring corresponds to the output port of the pressure-compensated dripper.
[0013] Furthermore, a guide tip is fixedly installed on the lower center of the guide ring.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. The filter screen of this utility model can effectively filter impurities in the water flow, avoid clogging the pressure-compensated drip head, and the impurities can gradually fall under the action of gravity and fall into the collection bottle of the collection component, avoiding the accumulation of impurities inside the drip irrigation tape body. By rotating the collection bottle, the collection bottle can be disassembled, making it easy to clean the impurities inside. The transparent structure makes it easy to observe the amount of impurities accumulated inside the collection bottle.
[0016] 2. Water droplets discharged from the pressure-compensated dripper can flow down along the guide ring, and converge and drip at the guide tip. The guide ring can prevent water from spreading on the surface of the drip tape body, thus reducing the local flow rate. The guide tip can effectively guide the droplet position and accurately control the drip irrigation position. Attached Figure Description

[0023] 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;
[0024] Reference Figure 1-4A low-flow compensating drip irrigation tape includes a drip irrigation tape body 1, a pressure compensating dripper 2 fixedly installed on the upper side of the drip irrigation tape body 1, a collection component fixedly installed on the lower side of the drip irrigation tape body 1, and a filter screen 6 fixedly installed inside the drip irrigation tape body 1, with the filter screen 6 located between the pressure compensating dripper 2 and the collection component.
[0025] The number of pressure-compensating drippers 2 can be multiple. The filter screen 6 and the collection component are located at the water inlet. The filter screen 6 can effectively filter impurities in the water flow to avoid clogging the pressure-compensating drippers 2. Impurities can gradually fall under the action of gravity and fall into the collection component to prevent impurities from accumulating inside the drip irrigation tape body 1.
[0026] Filter screen 6 features a double-layer design with 120-mesh stainless steel mesh, the interlaced mesh openings forming a three-dimensional filtration layer capable of intercepting particles ≥0.1mm. Filter screen 6 is installed at a 15° angle, allowing gravity to guide impurities to slide down into the collection assembly.
[0027] When the drip irrigation tape body 1 is in use, the pressure-compensating dripper 2 is positioned at the top and the collection component is positioned at the bottom. When the water supply stops, the water remaining in the drip irrigation tape body 1 will naturally drain downwards, which can carry away the tiny impurities attached to the outlet of the pressure-compensating dripper 2 and keep the water flow unobstructed.
[0028] The collection assembly includes a connecting tube 4 and a collection bottle 5. The connecting tube 4 is fixedly installed on the lower side of the drip irrigation tape body 1, and the bottom end of the connecting tube 4 is threadedly connected to the bottle opening of the collection bottle 5. The collection bottle 5 is transparent.
[0029] The collection bottle 5 can collect the filtered impurities. By rotating the collection bottle 5, it can be disassembled to facilitate the cleaning of the impurities inside. The transparent structure makes it easy to observe the amount of impurities accumulated inside the collection bottle 5.
[0030] A flow guide ring 3 is fixedly installed on the outer surface of the drip irrigation tape body 1, and the flow guide ring 3 corresponds to the output port of the pressure-compensated dripper 2. A flow guide tip 7 is fixedly installed in the middle of the lower side of the flow guide ring 3.
[0031] Water droplets discharged from the pressure-compensated dripper 2 can flow down along the guide ring 3 and converge and drip at the guide tip 7. The guide ring 3 can prevent water from spreading on the surface of the drip irrigation tape body 1 and reducing the local flow rate. The guide tip 7 can effectively guide the water droplet's landing position and accurately control the drip irrigation position.
