Abstract
Description
Technical Field
[0001] This utility model relates to the field of irrigation equipment, and more specifically, to root-sensing drip irrigation tape. Background Technology
[0002] Drip tape is an important irrigation tool in drip irrigation systems. It uses a plastic tube as a carrier and has drip holes distributed in a specific pattern to accurately deliver water to the roots of plants. In actual irrigation, water enters the drip tape through the pipeline system and drips slowly from the drip holes to moisten the soil around the plant roots and provide the water needed for plant growth.
[0003] Chinese Patent Announcement No. CN213662893U discloses a drip irrigation tape. This patent reduces the impact force of water flow through a spiral flow channel. Through a filter element, a first filter plate, and a second filter plate, it achieves multiple filtrations of drip irrigation water, allowing the drip irrigation water to flow smoothly in the drip irrigation tape and ensuring the normal operation of drip irrigation.
[0004] However, the drip irrigation tapes mentioned in the above patents are difficult to accurately supply water according to the real-time water demand of plant roots during the irrigation process, often resulting in insufficient or excessive irrigation, which wastes water resources and is not conducive to plant growth. Specifically, these traditional drip irrigation tapes lack the ability to actively sense and dynamically adjust the soil moisture status. The water flow rhythm of their drip holes is mostly controlled by preset flow channel parameters or external manual operation, and cannot be automatically adjusted according to the changes in water around the plant roots. Utility Model Content
[0005] 1. Technical problems to be solved
[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a root-sensing drip irrigation tape. It can absorb water through the liquid-guiding cotton, causing the sensing cotton to expand and push the sealing pad to block the water passage, thus avoiding over-irrigation. When water is scarce, the sensing cotton contracts, causing the sealing pad to retract and the water passage to open, allowing water to be replenished. This can accurately match the real-time water demand of the plant roots, reduce ineffective water consumption, and significantly save water resources.
[0007] 2. Technical Solution
[0008] To solve the above problems, the present invention adopts the following technical solution.
[0009] A root-sensing drip irrigation tape includes a water guide pipe, the lower end of which is fixedly connected to a drip irrigation plate. Multiple fixed cylinders and multiple spray heads are fixedly connected to the lower end of the drip irrigation plate, and these are arranged in a staggered pattern. Multiple micro-holes are formed on the outer end of each fixed cylinder. Multiple water passage holes corresponding to the spray heads are formed in the middle of the drip irrigation plate. Liquid-guiding cotton is placed inside each fixed cylinder and embedded in the lower end of the drip irrigation plate. Perforations are formed on the inner wall of each water passage hole, and a sealing gasket is slidably connected within each perforation. A sensing cotton, which is water-absorbing and expanding, is fixedly connected between the sealing pad and the liquid-guiding cotton. It is placed at the root position of the plant through the water-guiding pipe. The fixing cylinder is inserted into the soil. The liquid-guiding cotton absorbs water from the soil, causing the sensing cotton to increase in volume and push the sealing pad to block the water passage, preventing over-irrigation. When irrigation is insufficient, the soil lacks water and the liquid-guiding cotton cannot absorb enough water. The sensing cotton does not come into contact with water and shrinks itself, pulling the sealing pad back into the perforation. This allows water in the water-guiding pipe to flow from the water passage to the sprinkler head for spray irrigation.
[0010] Furthermore, the upper end of the drip irrigation plate is provided with multiple pull-out grooves corresponding to the spray heads, and magnetic baffles are slidably connected in the pull-out grooves. The magnetic baffles can block and filter impurities in the water supplied in the water pipe.
[0011] Furthermore, the magnetic baffle includes a pull plate, which is slidably connected to the pull-out groove. The pull plate has a placement hole in the middle, and a filter screen is provided in the placement hole. The filter screen can filter water, and the pull plate can be removed to replace the filter screen.
[0012] Furthermore, the magnetic baffle also includes a pull block, which is fixedly connected to the outer end of the draw plate. The outer surface of the pull block is provided with anti-slip texture. The magnetic baffle can be easily pulled out by the pull block to replace the filter.
[0013] Furthermore, a magnet is fixedly connected to the inner wall of the pull-out groove, which can magnetically attract and fix the magnetic baffle to improve the stability of the magnetic baffle after installation.
[0014] Furthermore, a cone block is fixedly connected to the lower end of the fixing cylinder, which facilitates the insertion of the fixing cylinder into the soil.
[0015] 3. Beneficial effects
[0016] Compared with existing technologies, the advantages of this utility model are:
[0017] (1) This solution uses the liquid-absorbing cotton to absorb water and cause the sensing cotton to expand, which pushes the sealing pad to block the water passage and avoids over-irrigation. When there is a water shortage, the sensing cotton contracts and causes the sealing pad to retract, opening the water passage to replenish water. This can accurately match the real-time water demand of the plant roots, reduce ineffective water consumption, and significantly save water resources.
[0018] (2) In this scheme, the fixed cylinder and the cone block not only facilitate the quick insertion and stable fixation of the device into the soil, but also ensure the full contact between the liquid-conducting cotton and the soil environment through the micro-holes at the outer end of the fixed cylinder, thus ensuring the sensitivity of the moisture sensing.
[0019] (3) In this solution, the magnetic baffle and filter screen can effectively intercept impurities in the water and prevent the spray head from clogging. The magnetic attraction and fixing structure of the magnet and magnetic baffle not only ensures the installation stability of the filter components, but also enables quick replacement of the filter screen through the pull-out method. Maintenance can be completed without tools, which greatly improves maintenance efficiency. Attached Figure Description

[0029] Example 1:
[0030] Please see Figure 1-4 The root-sensing drip irrigation tape includes a water guide pipe 1, with a drip irrigation plate 2 fixedly connected to the lower end of the water guide pipe 1. Multiple fixed cylinders 3 and multiple sprinkler heads 4 are fixedly connected to the lower end of the drip irrigation plate 2, and the fixed cylinders 3 and sprinkler heads 4 are staggered. Multiple micro-holes are opened on the outer end of the fixed cylinders 3. Multiple water passage holes corresponding to the sprinkler heads 4 are opened in the middle of the drip irrigation plate 2. Liquid-guiding cotton 5 is provided inside the fixed cylinders 3 and is embedded in the lower end of the drip irrigation plate 2. Perforations are opened on the inner wall of the water passage holes, and a sealing gasket 7 is slidably connected within the perforations. Sensing cotton 6 is fixedly connected between the sealing gasket 7 and the liquid-guiding cotton 5, and the sensing... The cotton 6 is a water-absorbing and expanding cotton. By placing the water-conducting pipe 1 at the root position of the plant and inserting the fixing cylinder 3 into the soil, the liquid-conducting cotton 5 absorbs soil moisture through the micropores at the outer end of the fixing cylinder 3, causing the sensing cotton 6 to absorb water and expand, pushing the sealing pad 7 to seal the water passage and prevent over-irrigation. When the soil is short of water, the liquid-conducting cotton 5 does not absorb enough water, causing the sensing cotton 6 to shrink. The sealing pad 7 retracts, opening the water passage, and water is irrigated through the sprinkler head 4. This mechanical linkage can automatically adjust according to soil moisture, achieve precise irrigation, improve water resource utilization, and the staggered distribution of the fixing cylinder 3 and sprinkler head 4 ensures uniform irrigation, which is beneficial to plant growth.
[0031] The upper end of the drip irrigation plate 2 has multiple pull-out grooves corresponding to the sprinkler heads 4. Magnetic baffles 8 are slidably connected in the pull-out grooves. By sliding the magnetic baffles 8 into the pull-out grooves to the position corresponding to the sprinkler heads 4, impurities in the water can be intercepted to prevent the sprinkler heads 4 from clogging and ensure smooth irrigation. When maintenance is required, the magnetic baffles 8 can be pulled out. This design effectively filters impurities and facilitates maintenance, improving the stability and service life of the drip irrigation system.
[0032] The magnetic baffle 8 includes a pull plate 81, which is slidably connected to the pull-out groove. The pull plate 81 has a placement hole in the middle, and a filter screen 82 is placed in the placement hole. Water enters the spray head 4 after being filtered by the filter screen 82 on the pull plate 81, which can reduce the impact of impurities on the spray head 4 and improve the filtration effect. When the filter screen 82 is clogged, the pull plate 81 can be removed from the pull-out groove to replace the filter screen 82. The operation is simple, reducing the difficulty and cost of maintenance and ensuring continuous and effective filtration.
[0033] The magnetic baffle 8 also includes a pull block 83, which is fixedly connected to the outer end of the drawer plate 81. The outer surface of the pull block 83 is provided with anti-slip texture. By holding the pull block 83 with anti-slip texture, the drawer plate 81 can be pulled, providing a convenient force point for taking out and putting in the magnetic baffle 8. The anti-slip texture prevents slipping, making the pulling operation more effortless and stable, and improving the ease of operation when maintaining the magnetic baffle 8.
[0034] A magnet 9 is fixedly connected to the inner wall of the pull-out groove. After the magnetic baffle 8 is inserted into the pull-out groove, the magnet 9 in the pull-out groove will attract the baffle, making it difficult for it to move when water flows or vibrates slightly, thus ensuring the stability of the filter position and guaranteeing the continuous and reliable filtration effect.
[0035] A cone block 10 is fixedly connected to the lower end of the fixed cylinder 3. With the help of the cone block 10 at the lower end of the fixed cylinder 3, the fixed cylinder 3 can be inserted into soils of different textures more easily, reducing insertion resistance and making the field deployment of drip irrigation tape more labor-saving and efficient, suitable for various soil environments.
[0036] Working principle:
[0037] First, place the water pipe 1 at the root system of the vegetation. Insert the fixing cylinder 3 into the soil through the cone block 10 at the lower end of the fixing cylinder 3. At this time, the fixing cylinder 3 at the lower end of the drip irrigation plate 2 and the sprinkler head 4 are staggered. The liquid-guiding cotton 5 inside the fixing cylinder 3 absorbs soil moisture through the micropores at the outer end of the fixing cylinder 3. When the soil moisture is sufficient, the liquid-guiding cotton 5 absorbs enough water to cause the sensing cotton 6 to absorb water and expand, thereby pushing the sealing pad 7 to slide in the perforation of the inner wall of the water passage and block the water passage to avoid over-irrigation. When the soil is short of water, the liquid-guiding cotton 5 does not absorb enough water, causing the sensing cotton 6 to shrink and pull the sealing pad 7. Water from the water pipe 1 flows through the water passage in the middle of the drip irrigation plate 2 to the sprinkler head 4 to irrigate the plant roots. At the same time, the magnetic baffle 8 in the pull-out groove at the upper end of the drip irrigation plate 2 filters the water flow through the filter screen 82 placed in the middle hole of the pull plate 81 to prevent impurities from clogging the sprinkler head 4. The magnet 9 on the inner wall of the pull-out groove attracts the magnetic baffle 8 to ensure its stability. When maintenance is required, the magnetic baffle 8 can be pulled out from the pull-out groove by the pull block 83 with anti-slip texture on the outer end of the pull plate 81 to replace or clean the filter screen 82, thus completing the entire process of precise irrigation on demand.
[0038] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
