Abstract
Description
Technical Field
[0001] This utility model relates to the field of irrigation dripper technology, and in particular to an anti-clogging dripper for water-saving irrigation in the field. Background Technology
[0002] As a core component of field water-saving irrigation systems, drip emitters directly control the outflow pattern and precision of irrigation water, and are widely used in irrigation scenarios for field crops, cash crops, and facility agriculture. Their core function is to transform the water flow within the pipe into uniform water droplets, precisely delivering them to the crop root zone to achieve integrated water and fertilizer supply, reducing water waste while ensuring nutrient absorption by crops.
[0003] Currently, irrigation drippers require water to be filtered before entering the irrigation pipe and finally flowing out of the dripper. Although this method can minimize impurities entering the dripper, impurities will gradually increase over time, affecting the use of the dripper and even causing blockage. Therefore, an anti-clogging dripper for water-saving irrigation in the field is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an anti-clogging dripper for water-saving irrigation in the field. It aims to improve the existing technology where irrigation drippers rely on external filters for filtration. After long-term use, impurities will gradually accumulate inside, which can easily cause dripper clogging, affect irrigation effect, and lead to water waste and insufficient crop nutrient supply.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a clog-resistant dripper for water-saving irrigation in fields, comprising an upper shell and a lower shell, wherein a water inlet head is fixedly connected to the upper shell, and a pressure compensation component is disposed in the upper shell; a water outlet head is fixedly connected to the lower shell, and an anti-clogging component is disposed in the lower shell, the anti-clogging component comprising:
[0006] A collection ring is detachably connected to the lower shell by bolts, and the lower shell has an opening.
[0007] A blocking ring is fixedly connected to the inner wall of the lower shell.
[0008] As a further description of the above technical solution:
[0009] A sealing ring is embedded in the side of the collecting ring near the lower shell, and the sealing ring abuts against the lower shell.
[0010] As a further description of the above technical solution:
[0011] The upper shell and the lower shell are detachably connected by bolts.
[0012] As a further description of the above technical solution:
[0013] The lower shell has an inlay groove, and a sealing ring is inlaid and installed in the inlay groove.
[0014] As a further description of the above technical solution:
[0015] The inner wall of the end of the water inlet head furthest from the upper shell is tapered.
[0016] As a further description of the above technical solution:
[0017] The pressure compensation component includes a fixed sleeve and an elastic diaphragm. A through groove is provided on the outer wall of the fixed sleeve, and the fixed sleeve and the elastic diaphragm are fixedly connected.
[0018] As a further description of the above technical solution:
[0019] The elastic diaphragm is located directly above the water outlet.
[0020] As a further description of the above technical solution:
[0021] A spiral strip is fixedly connected to the inner wall of the water outlet head. Multiple sets of the spiral strip are arranged in a circular array.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, by using the anti-clogging component, some impurities in the water flow can be blocked by the blocking ring, so that the impurities are intercepted after flowing into the collection ring, reducing the impurities entering the water outlet. At the same time, the spiral strip in the water outlet can also guide the water flow to form a rotating flush, reducing the adhesion of impurities, greatly reducing the probability of clogging, and ensuring the continuity of irrigation.
[0024] 2. In this utility model, the collecting ring is detachably connected by bolts. It can be disassembled periodically to clean internal impurities. The sealing ring ensures a tight seal to prevent leakage. At the same time, through the use of the pressure compensation component, when the water inlet is no longer being transported, the water flow squeezing force on the elastic diaphragm is reduced, resulting in smaller deformation of the elastic diaphragm. This reduces the obstruction of the water flowing out of the outlet, increases the flow rate of the water from the outlet, and further reduces the adhesion of impurities. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-3 This utility model provides an embodiment of an anti-clogging dripper for water-saving irrigation in fields, comprising an upper shell 1 and a lower shell 2. The lower shell 2 has an inlay groove, and a sealing ring 101 is inlaid in the inlay groove. In this way, the sealing effect after the upper shell 1 and the lower shell 2 are installed can be improved. A water inlet head 3 is fixedly connected to the upper shell 1. The water inlet head 3 is provided with a threaded groove to facilitate the connection between the water inlet head 3 and the irrigation pipe. A pressure compensation component 4 is provided in the upper shell 1. A water outlet head 5 is fixedly connected to the lower shell 2. Through the use of the pressure compensation component 4, the water flow from the water outlet head 5 can be relatively stable and uniform. An anti-clogging component 6 is provided in the lower shell 2.
[0033] The anti-clogging component 6 includes a collection ring 61 and a blocking ring 62. The collection ring 61 is detachably connected to the lower shell 2 by bolts. The lower shell 2 has an opening 63. The blocking ring 62 is fixedly connected to the inner wall of the lower shell 2. A spiral strip 51 is fixedly connected to the inner wall of the water outlet 5. Multiple sets of spiral strips 51 are arranged in a circular array. During the water flow, some impurities in the water flow can be blocked by the blocking ring 62, so that the impurities are intercepted after flowing into the collection ring 61, reducing the impurities entering the water outlet 5. After the collection ring 61 collects a certain amount of impurities, the impurities can be cleaned by removing the collection ring 61. At the same time, the spiral strips 51 in the water outlet 5 can also guide the water flow to form a rotating flush, reducing the adhesion of impurities, greatly reducing the probability of clogging, and ensuring the continuity of irrigation.
[0034] A sealing ring 64 is embedded on the side of the collecting ring 61 near the lower shell 2. The sealing ring 64 abuts against the lower shell 2. The use of the sealing ring 64 ensures that the collecting ring 61 can stably abut against the lower shell 2 after installation, thereby improving the sealing effect.
[0035] The inner wall of the end of the water inlet head 3 away from the upper shell 1 is tapered. This design allows the water to flow faster when it enters the water inlet head 3, and prevents impurities in the water from adhering to the inner wall of the water inlet head 3.
[0036] Reference Figures 2-4 The pressure compensation component 4 includes a fixed sleeve 41 and an elastic diaphragm 43. A through groove 42 is provided on the outer wall of the fixed sleeve 41. The fixed sleeve 41 and the elastic diaphragm 43 are fixedly connected. The elastic diaphragm 43 is located directly above the water outlet 5. When the irrigation system pressure increases, the water flow squeezes the elastic diaphragm 43 to make it bulge downward, reducing the flow cross-section of the water outlet 5. When the pressure decreases, the diaphragm elastically resets and expands the channel. Through this adaptive adjustment, the water flow rate is ensured to be unaffected by the fluctuation of the pipeline pressure, providing uniform irrigation for crops. Furthermore, when the water in the inlet head 3 is no longer being transported, the water flow squeezing effect on the elastic diaphragm 43 is reduced, resulting in smaller deformation of the elastic diaphragm 43. This reduces the obstruction of the water flowing out of the water outlet 5, increases the flow rate of the water from the water outlet 5, and further reduces the adhesion of impurities.
[0037] The upper shell 1 and the lower shell 2 are detachably connected by bolts, which facilitates the replacement and maintenance of the elastic diaphragm 43.
[0038] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here. The standard parts used in this application can all be purchased from the market. The specific connection methods of each part are all connected by conventional means such as riveting and welding that are mature in the prior art. The standard parts are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art.
[0039] Working principle: In use, the dripper is precisely connected to the irrigation pipe using the threaded groove on the inlet head 3. Then, the upper shell 1 and lower shell 2 are assembled with bolts. The sealing ring 101 in the groove of the lower shell 2 is pressed and fitted. After the irrigation system is started, water flows through the irrigation pipe into the inlet head 3. The conical inner wall of the end of the inlet head 3 away from the upper shell 1 guides the water flow to accelerate, preventing impurities from adhering and accumulating on the inner wall of the inlet head 3. After the water flows into the upper shell 1, when the irrigation system pressure increases, the water flow squeezes the elastic diaphragm 43, causing it to bulge downwards and reducing the flow cross-section of the outlet head 5. When the pressure decreases, the diaphragm elastically returns to its original position, expanding the channel. Through this adaptive adjustment, the water flow rate is ensured to be unaffected by fluctuations in the pipe network pressure, providing uniform irrigation for the crops.
[0040] After the water flows into the lower shell 2 through the channel 42, the blocking ring 62 on the inner wall of the lower shell 2 first intercepts the impurities in the water flow and flows into the collection ring 61 through the opening 63 of the lower shell 2. The small impurities are intercepted by the collection ring 61, effectively reducing the impurities entering the outlet head 5. At the same time, the spiral strips 51 of the annular array on the inner wall of the outlet head 5 guide the water flow to form a rotating scouring, further reducing the adhesion and deposition of impurities on the inner wall of the outlet head 5.
[0041] When the irrigation system stops supplying water, the water flow from the inlet head 3 is interrupted, the pressure on the elastic diaphragm 43 decreases, and the deformation decreases accordingly. This reduces the obstruction of the water flow from the outlet head 5, allowing the residual water to flow out at a faster rate. The impact force of the water flow is used to clean up any trace impurities that may be attached to the outlet head 5.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
