Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, specifically to an anti-clogging filter structure for orchard drip irrigation pipes. Background Technology

[0002] Drip irrigation pipes are a core component of orchard irrigation systems, precisely delivering water and nutrients to the vicinity of fruit tree roots to meet the water needs of fruit trees at different growth stages. They reduce water evaporation and loss, improve water resource utilization, and avoid soil compaction problems that can occur with traditional irrigation. In large-scale orchards, drip irrigation pipes can be flexibly laid out to match the planting layout, creating a stable water supply environment for fruit trees, facilitating refined orchard management, and supporting healthy tree growth and stable yields.

[0003] Utility model patent CN212381841U discloses a drip irrigation pipe, which includes a water supply pipe, a dripper, and an elastic ring. The dripper is cylindrical, with an annular mounting groove on its outer wall. A water outlet hole is formed through the annular mounting groove, and the edge of the groove has an inner chamfer. The elastic ring is fitted onto the dripper and located within the annular mounting groove, covering the water outlet hole. The dripper is housed in the water supply pipe, which has a matching water outlet that spans both sides of the annular mounting groove. This design improves the anti-clogging performance and reliability of the drip irrigation pipe.

[0004] This drip irrigation pipe only uses an elastic ring to block the water outlet of the dripper, passively reducing the amount of impurities entering the outlet. This means that impurities in the water cannot be intercepted before the water reaches the dripper. If the impurity content in the irrigation water is high, some impurities will still adhere to the gap between the elastic ring and the annular mounting groove with the water flow. Over time, this can easily lead to increased resistance to water flow and thus poor water flow. In view of this, we propose an anti-clogging filter structure for orchard drip irrigation pipes. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging filter structure for orchard drip irrigation pipes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anti-clogging filtration structure for orchard drip irrigation pipes includes a main irrigation pipe with a pipe filtration device installed within it. The pipe filtration device includes a bottom shell, a cover installed at the head end of the bottom shell, and a filtration assembly rotatably connected between the bottom shell and the cover. The tail end of the bottom shell has a drain pipe connected to the main irrigation pipe, and a first support frame is fixed inside the drain pipe. The bottom end of the bottom shell has a collection seat, and the head end of the cover has an inlet pipe connected to the main irrigation pipe, with a second support frame inside the inlet pipe. The filtration assembly is rotatably connected between the first and second support frames. The filtration assembly includes a rotating shaft, a mesh bucket installed at the end of the rotating shaft, and a drive impeller fixed at the head end of the rotating shaft. The mesh bucket has a conical mesh structure with its pointed end facing the bottom shell.

[0008] Preferably, the front end of the bottom shell has a conical cavity structure, the drain pipe is connected to the conical cavity, a friction ring is embedded on the inner wall of the conical cavity, and the outer surface of the net bucket is in contact with the friction ring.

[0009] In this setup, the conical cavity guides the water flow to the drain pipe, and the friction ring scrapes off impurities from the surface of the filter basket as it rotates, achieving self-cleaning of the filter basket and preventing residual impurities from affecting filtration.

[0010] Preferably, the collecting seat is hollow and communicates with the interior of the bottom shell, and the bottom edge of the net extends toward the top opening of the collecting seat.

[0011] In this design, the collection base can collect the impurities that fall from the net bucket. The design of the net bucket's edge extending towards the opening can reduce the scattering of impurities inside the bottom shell and facilitate the directional collection of impurities.

[0012] Preferably, the outer end of the collection seat is connected to a slag discharge pipe, and the end of the slag discharge pipe is connected to a valve.

[0013] In this setup, the slag discharge pipe can guide impurities out of the collection seat, and the valve can control the opening and closing of the slag discharge pipe to achieve centralized discharge of impurities and prevent water leakage during filtration.

[0014] Preferably, the tail end of the cover has a recessed cavity, which is connected to the liquid inlet pipe, and the drive impeller is sleeved in the recessed cavity.

[0015] In this design, the concave cavity allows the water flow in the inlet pipe to precisely flush the impeller, ensuring that the impeller stably obtains power.

[0016] Preferably, a bearing is installed at the center of the first support frame, and the end of the rotating shaft is inserted into the bearing inside the first support frame, and the end of the rotating shaft is rotatably connected to the first support frame through the bearing.

[0017] In this configuration, the bearing reduces the frictional resistance between the shaft and the first support frame, making the shaft end rotate more smoothly, while also providing stable support to the shaft and preventing it from wobbling.

[0018] Preferably, a bearing is installed at the center of the second support frame, and the first end of the rotating shaft is inserted into the bearing inside the second support frame, and the first end of the rotating shaft is rotatably connected to the second support frame through the bearing.

[0019] In this configuration, the bearing reduces friction between the first end of the shaft and the second support frame, preventing wear on the first end of the shaft. At the same time, it works with the first support frame to support both ends of the shaft, improving the rotational stability of the shaft.

[0020] Preferably, a first connecting edge is provided at the first edge of the outer peripheral surface of the bottom shell, and a second connecting edge is provided at the last edge of the outer peripheral surface of the cover shell, and the first connecting edge and the second connecting edge are fixedly connected by bolts.

[0021] In this configuration, the first and second connecting edges, together with bolts, enable a detachable connection between the bottom shell and the cover, facilitating the later opening of the device for maintenance or replacement of internal components.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. The anti-clogging filter structure of the orchard drip irrigation pipe, by setting up a special filter component, can actively intercept impurities such as mud, sand and fertilizer residue in the water before the water flows into the subsequent pipe or dripper. It can reduce the amount of impurities transported to the water outlet from the upstream stage of the water flow, reduce the probability of impurities accumulating in the subsequent water outlet channel, and thus better maintain the smoothness of the water outlet channel.

[0024] 2. The orchard's drip irrigation pipe anti-clogging filter structure, through the set collection seat, allows impurities that have been intercepted by the net bucket to be collected in the collection seat when they are thrown out. By opening the valve, the impurities can be discharged, avoiding the accumulation of impurities in the pipe filter device and maintaining the long-term smooth flow of the pipe filter device.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0034] Please see Figures 1-5 The orchard drip irrigation pipe anti-clogging filtration structure includes an irrigation main pipe 100, in which a pipe filter device 200 is installed. The pipe filter device 200 can centrally filter the water flow in the irrigation main pipe 100 to prevent impurities from directly entering the subsequent drip irrigation components. The pipe filter device 200 includes a bottom shell 210, a cover 220 installed at the head end of the bottom shell 210, and a filter assembly 230 rotatably connected between the bottom shell 210 and the cover 220. The bottom shell 210 and the cover 220 cooperate to form a closed filtration space, providing an installation and working environment for the filter assembly 230. The filter assembly 230 includes a rotating shaft 231, a net bucket 232 installed at the end of the rotating shaft 231, and a drive impeller 233 fixed at the head end of the rotating shaft 231. The filter assembly 230 is used to filter impurities in the water. The net bucket 232 can directly intercept impurities such as mud, sand and fertilizer residue in the water flow. The drive impeller 233 can convert the impact force of the water flow into rotational power. When the water flow in the irrigation main pipe 100 passes through the pipe filter device 200, it will wash the drive impeller 233, causing the drive impeller 233 to drive the net bucket 232 to rotate through the rotating shaft 231 and throw the intercepted impurities outward under the action of centrifugal force. Centrifugal force can help impurities detach from the surface of the net bucket 232 and reduce the amount of impurities attached to the net bucket 232.

[0035] like Figures 1-4As shown, in this utility model, the tail end of the bottom shell 210 is provided with a drain pipe 211 connected to the irrigation main pipe 100. The drain pipe 211 can send the filtered water back to the irrigation main pipe 100, realizing the directional delivery of the filtered water. A first support frame 212 is fixed inside the drain pipe 211. The first support frame 212 can support the end of the rotating shaft 231, ensuring the stable rotation of the rotating shaft 231. A bearing is installed at the center of the first support frame 212. The end of the rotating shaft 231 is inserted into the bearing inside the first support frame 212. The end of the rotating shaft 231 is rotatably connected to the first support frame 212 through the bearing. The bearing can reduce the frictional resistance between the rotating shaft 231 and the first support frame 212, making the rotating shaft 231 rotate more smoothly. The head end of the cover 220 is provided with a drain pipe 211 connected to the irrigation main pipe 100. The inlet pipe 221 is connected to guide the water flow in the irrigation main pipe 100 into the pipe filter device 200, ensuring a stable water flow into the filter space. A second support frame 222 is provided inside the inlet pipe 221. The second support frame 222 cooperates with the first support frame 212 to support the rotating shaft 231 from both ends, further improving the rotational stability of the rotating shaft 231. A bearing is installed at the center of the second support frame 222. The head end of the rotating shaft 231 is inserted into the bearing inside the second support frame 222. The head end of the rotating shaft 231 is rotatably connected to the second support frame 222 through the bearing. The bearing here also plays a role in reducing friction and preventing the head end of the rotating shaft 231 from being damaged by friction, so that the filter assembly 230 is rotatably connected between the first support frame 212 and the second support frame 222.

[0036] like Figures 1-4 As shown, specifically, a first connecting edge 217 is provided at the first edge of the outer peripheral surface of the bottom shell 210, and a second connecting edge 224 is provided at the last edge of the outer peripheral surface of the cover 220. The first connecting edge 217 and the second connecting edge 224 are fixedly connected by bolts. The cooperation between the first connecting edge 217 and the second connecting edge 224 can realize the detachable connection between the bottom shell 210 and the cover 220, which facilitates the maintenance or replacement of the internal components of the pipeline filter device 200 in the later stage.

[0037] like Figure 2 , Figure 3 and Figure 5As shown, the net bucket 232 further has a conical mesh structure with a cone apex angle of 45° and a mesh aperture of 0.5-1mm. The pointed end faces the bottom shell 210. This cone apex angle range can both utilize gravity to help impurities gather at the bottom of the net bucket 232 and avoid excessive angle that would increase water flow resistance. The 0.5-1mm mesh aperture can accurately intercept common impurities such as silt and fertilizer residue, while ensuring smooth water flow. This improves filtration accuracy while also taking into account impurity gathering efficiency. The front end of the bottom shell 210 has a conical cavity structure. The conical cavity structure can guide the water flow towards the drain pipe 211 and at the same time provide a matching rotation space for the net bucket 232. The drain pipe 211 is connected to the conical cavity. A friction ring 213 is embedded in the inner wall of the conical cavity. The friction ring 213 is made of wear-resistant rubber or polytetrafluoroethylene. The outer surface of the net bucket 232 is in contact with the friction ring 213. This material has both wear resistance and flexibility. It can effectively scrape off the impurities attached to the surface of the net bucket 232 when it rotates, realizing the self-cleaning of the net bucket 232. It can also avoid wear on the net bucket 232 during the scraping process and maintain the filtration capacity of the net bucket 232 for a long time.

[0038] like Figure 3 As shown, in addition, a cavity 223 is provided at the tail end of the cover 220. The cavity 223 is connected to the liquid inlet pipe 221. The drive impeller 233 is sleeved in the cavity 223. The cavity 223 can limit the drive impeller 233 to prevent the drive impeller 233 from deviating when rotating, and at the same time ensure that the water flow in the liquid inlet pipe 221 can accurately flush the drive impeller 233.

[0039] like Figure 3 As shown, it is worth noting that a collection seat 214 is provided at the bottom end of the bottom shell 210. The collection seat 214 can receive impurities that fall off the net hopper 232, realizing the centralized collection of impurities. The collection seat 214 is hollow and connected to the interior of the bottom shell 210. The bottom edge of the net hopper 232 extends to the top opening of the collection seat 214. This design makes it easier for impurities on the net hopper 232 to fall into the collection seat 214, reducing the scattering of impurities inside the bottom shell 210. The outer end of the collection seat 214 is connected to a slag discharge pipe 215. The slag discharge pipe 215 can discharge the impurities in the collection seat 214 to the pipeline filter device 200. The end of the slag discharge pipe 215 is connected to a valve 216. The valve 216 can control the opening and closing of the slag discharge pipe 215, which facilitates the centralized discharge of impurities when needed and avoids water leakage from the slag discharge pipe 215 during the filtration process.

[0040] In this embodiment, the anti-clogging filter structure for orchard drip irrigation pipes works as follows: First, water from the irrigation main pipe 100 enters the cavity 223 of the pipe filter device 200 through the inlet pipe 221, causing the impeller 233 to rotate. Then, the impeller 233 drives the mesh bucket 232 to rotate synchronously via the rotating shaft 231. When the water flows through the mesh bucket 232, impurities are intercepted by the 0.5-1mm mesh openings. The filtered water then enters the outlet through the conical cavity of the bottom shell 210. The liquid flows through pipe 211 and back to irrigation main pipe 100; then, the net bucket 232 rotates with a 45° cone apex angle structure, and its outer surface is in contact with the friction ring 213 made of wear-resistant rubber or polytetrafluoroethylene. The friction ring 213 scrapes off the impurities on the surface of the net bucket 232, and the impurities fall into the collection seat 214 under the action of centrifugal force and gravity; finally, when a certain amount of impurities accumulate in the collection seat 214, the valve 216 is opened, and the impurities are discharged from the system through the slag discharge pipe 215, completing one filtration and slag discharge process.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
