Description

Technical Field

[0001] This utility model relates to the field of drip irrigation device technology, and in particular to a drip irrigation device. Background Technology

[0002] Drip irrigation, as a core technology for water-saving irrigation in modern agriculture, improves water resource utilization efficiency by precisely delivering water to the root zone of crops. In the field of Shatang pomelo cultivation, drip irrigation tape is laid along the root system of Shatang pomelo plants. Its surface is covered with precision water outlets, which can slowly soak the soil around the roots in the form of fine streams or droplets, ensuring that the pomelo trees receive a uniform and appropriate amount of water during their growth.

[0003] Existing patent (publication number: CN221510506U) discloses "This utility model discloses a drip irrigation device, including a base plate, a connecting plate, and a water-blocking head. A water guide pipe is installed in the middle of the base plate, and a flow valve is installed at the upper end of the water guide pipe. The upper end of the water guide pipe is connected to a bottom box, and an outer box cover is installed at the upper end of the bottom box. An inlet pipe is connected to the upper end of the outer box cover. A connecting plate is installed on one side of the upper part of the base plate, and a movable plate is provided inside the connecting plate. An adjusting bolt is installed on the upper side of the connecting plate. A connecting pipe is connected to the lower end of the water guide pipe, and a diversion pipe is threaded onto the surface of the connecting pipe. This drip irrigation device can easily dilute and block the dripping water through the use of a sponge pad and a mesh inside the drip head, avoiding excessive water loss. At the same time, an anti-clogging mesh is provided at the outer end of the drip head, which can effectively protect the dripping holes of the drip head and prevent dirt from clogging the dripping holes and affecting drainage."

[0004] In the process of developing this application, the inventors discovered the following problems with the existing technology: When the filter screen of this drip irrigation device needs to be replaced, the adjusting bolt is turned, and then the movable plate is pushed upward, so that the movable plate drives the outer box cover upward to separate the outer box cover from the bottom box, thereby facilitating the cleaning and replacement of the filter screen inside the bottom box. However, the outer box cover is bulky and heavy, and it is labor-intensive and inefficient to separate it from the bottom box. Moreover, the cone-shaped filter screen inside causes impurities to easily accumulate at the bottom of the filter screen, which not only shortens the service life of the filter screen, but also greatly increases the replacement frequency, thereby increasing maintenance costs and causing many inconveniences to daily irrigation work.

[0005] Therefore, those skilled in the art have provided a drip irrigation device to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drip irrigation device. The filter plate inside the lower casing can filter the irrigation water, remove impurities from the water, prevent impurities from clogging the drip heads, ensure the normal operation of drip irrigation, and improve the stability and reliability of irrigation.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A drip irrigation device includes an upper housing and a lower housing. A rotating shaft is rotatably mounted inside the upper housing. Multiple propeller blades are fixedly mounted outside the rotating shaft. Multiple scrapers are fixedly mounted at the end of the rotating shaft away from the propeller blades. A water inlet pipe is fixedly mounted at the upper end of the upper housing.

[0009] A filter plate is slidably installed at the upper end of the lower housing, a sealing ring is fixedly installed at the upper end of the lower housing, a screw is rotatably installed on one side of the upper housing, the screw is externally threaded to one side of the lower housing, multiple support legs are fixedly installed on the outside of the upper housing, and a corrugated pipe is fixedly installed at the lower end of the lower housing.

[0010] Furthermore, the multiple scrapers are arranged on opposite sides of the upper housing inner wall, and the multiple support legs are slidably arranged on the outside of the lower housing inside.

[0011] Furthermore, the lower end of the upper housing is positioned above the sealing ring, and the lower outer end of the upper housing is slidably positioned inside the upper inner end of the lower housing.

[0012] Furthermore, a base is fixedly disposed between the lower ends of the plurality of support legs, and two handles are fixedly disposed on the upper end of the filter plate.

[0013] Furthermore, a medicine storage box is fixedly installed at the upper end of the upper box, and a second control valve is fixedly installed at the lower end of the medicine storage box. The output end of the second control valve is fixedly installed at the upper end of the upper box.

[0014] Furthermore, a first control valve is fixedly installed at the lower end of the corrugated pipe, and a water guide pipe is fixedly installed at the output end of the first control valve. Multiple drain pipes are externally threaded onto the water guide pipe.

[0015] Furthermore, each of the multiple drain pipes is threaded with multiple plugs on the outside, and each of the multiple drain pipes is threaded with multiple drip heads on the outside.

[0016] This utility model has the following beneficial effects:

[0017] 1. The drip irrigation device proposed in this utility model allows for the replacement of filter plates by rotating a screw, causing the lower housing to slide downwards along the screw and simultaneously slide down outside multiple support legs. This gradually increases the distance between the lower and upper housings, and the pressure of the upper housing on the sealing ring gradually disappears. When the distance between the two reaches a suitable level, the filter plate inside the lower housing is exposed, making it easy to remove the filter plate from the lower housing. The entire operation is relatively simple, requiring no multiple people to cooperate, reducing maintenance difficulty and labor costs, and avoiding the inconvenience of maintenance caused by bulky components.

[0018] 2. The drip irrigation device proposed in this utility model, when the water inlet pipe is opened, the water flow will impact the propeller blades, driving the rotating shaft to rotate, causing the scraper on the rotating shaft to rotate as well. The scraper will scrape the inner wall of the upper box, effectively preventing impurities from adhering to the inner wall. The filter plate at the upper end of the lower box will filter the water flow. The filter plate adopts a flat filter plate, which can reduce the accumulation of impurities, reduce the replacement frequency, save maintenance costs, reduce the possibility of drip head blockage, and ensure the normal operation of drip irrigation.

[0028] 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.

[0029] Reference Figures 1-7 One embodiment provided by this utility model:

[0030] A drip irrigation device includes an upper housing 1 and a lower housing 2. A rotating shaft 15 is rotatably installed at the upper end inside the upper housing 1. Multiple propeller blades 14 are fixedly installed outside the rotating shaft 15. Multiple scrapers 16 are fixedly installed at the end of the rotating shaft 15 away from the propeller blades 14. A water inlet pipe 12 is fixedly installed at the upper end of the upper housing 1.

[0031] A filter plate 17 is slidably installed at the upper end of the lower box 2. A sealing ring 19 is fixedly installed at the upper end of the lower box 2. A screw 3 is rotatably installed on one side of the upper box 1. The screw 3 is externally threaded to one side of the lower box 2. Multiple support legs 5 are fixedly installed on the outside of the upper box 1. A corrugated pipe 18 is fixedly installed at the lower end of the lower box 2.

[0032] Multiple scrapers 16 are arranged on opposite sides of the inner wall of the upper box 1. Multiple support legs 5 are slidably arranged inside the lower box 2. The lower end of the upper box 1 is arranged on the upper end of the sealing ring 19. The lower end of the outer side of the upper box 1 is slidably arranged inside the upper end of the lower box 2. A base 6 is fixedly arranged between the lower ends of the multiple support legs 5. Two handles 20 are fixedly arranged on the upper end of the filter plate 17.

[0033] A medicine storage tank 11 is fixedly installed at the upper end of the upper box 1. A second control valve 13 is fixedly installed at the lower end of the medicine storage tank 11. The output end of the second control valve 13 is fixedly installed at the upper end of the upper box 1. A first control valve 4 is fixedly installed at the lower end of the bellows 18. A water guide pipe 7 is fixedly installed at the output end of the first control valve 4. Multiple drain pipes 9 are externally threaded to the water guide pipe 7. Multiple plugs 8 are externally threaded to the multiple drain pipes 9. Multiple drip heads 10 are externally threaded to the multiple drain pipes 9.

[0034] Specifically, when drip irrigation is carried out on pomelos, the water inlet valve 12 is opened to allow water to flow into the upper chamber 1. Under the impact of the water flow, the propeller blade 14 will rotate, which in turn drives the rotating shaft 15 to rotate synchronously. This causes the scraper 16 on the outside of the rotating shaft 15 to make a circular motion, constantly scraping against the inner wall of the upper chamber 1. This not only achieves automatic cleaning of the upper chamber 1 and reduces the frequency of manual maintenance, but also effectively prevents impurities from adhering and accumulating, ensuring a clean environment inside the upper chamber 1.

[0035] If medication needs to be added during irrigation, simply open the second control valve 13 at the bottom of the storage tank 11. The medication will then slowly flow into the upper tank 1. Through the propeller blade 14 and scraper 16, the medication and water flow will mix, allowing irrigation, fertilization, and medication to be seamlessly connected. This ensures that the medication is evenly integrated into the irrigation water, improving the utilization rate of the medication and saving manpower and time costs. The flat filter plate 17 inside the lower tank 2 can intercept and filter impurities in the water, ensuring both water purity and irrigation uniformity, providing good water conditions for the growth of pomelos. The filtered water enters the water pipe 7 through the corrugated pipe 18 under the control of the first control valve 4. Users can flexibly install drip heads 10 on the drain pipe 9 according to actual irrigation needs. For interfaces that are not in use, they can be sealed with plugs 8. As the drip heads 10 slowly drip water, they can be adjusted as needed to achieve precise irrigation, regardless of the size of the planting area or the complex and varied terrain. The base 6 provides stable support for the support legs 5.

[0036] When the filter plate 17 needs to be replaced, the operator rotates the screw 3. Since the screw 3 is threadedly connected to the lower housing 2, the lower housing 2 slides downward along the outside of the screw 3 during the rotation of the screw 3. At the same time, it moves down smoothly under the guidance of multiple support legs 5. As the lower housing 2 gradually descends, the pressure of the upper housing 1 on the sealing ring 19 is gradually relieved. When it reaches the appropriate position, the filter plate 17 is fully exposed. At this time, it can be easily removed from the lower housing 2 through the handle 20 on the filter plate 17. The whole operation process is simple and quick, reduces the difficulty of maintenance, improves the efficiency of equipment maintenance, and ensures the continuous and efficient operation of the drip irrigation system.

[0037] Working principle: When drip irrigation is needed, open the valve on the inlet pipe 12. Water enters the upper tank 1 through the inlet pipe 12. The water flow impacts the propeller blade 14, causing the propeller blade 14 to drive the rotating shaft 15 to rotate. When the rotating shaft 15 rotates, the scraper 16 on its outside also rotates. The scraper 16 scrapes the inner wall of the upper tank 1 to prevent impurities from adhering to the inner wall. If it is necessary to add medicine for irrigation, the second control valve 13 at the lower end of the medicine storage tank 11 can be opened. The medicine in the medicine storage tank 11 flows into the upper tank 1 and mixes with the water. The filter plate 17 inside the lower tank 2 will filter the water and remove impurities. The filtered water will enter the corrugated pipe 18 and enter the water guide pipe 7 through the first control valve 4. According to the actual irrigation needs, drip heads 10 can be installed on the drain pipe 9. Excess interfaces can be blocked with plugs 8. Water drips slowly from the drip heads 10 to achieve drip irrigation for crops.

[0038] When the filter plate 17 needs to be replaced, by rotating the screw 3, since the screw 3 is externally threaded and connected to the inside of the lower housing 2, the lower housing 2 is slid outside the screw 3. At this time, the lower housing 2 will slide downward outside the multiple support legs 5, thereby gradually increasing the distance between it and the upper housing 1, causing the upper housing 1 to gradually release the pressure on the sealing ring 19. After the lower housing 2 moves down to the appropriate position, the filter plate 17 inside will be exposed. At this time, by holding the handle 20 at the upper end of the filter plate 17, it can be removed from the lower housing 2, making it convenient to replace the filter plate 17.

[0039] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
