Description

Technical Field

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

[0002] Simple drip irrigation devices are low-cost, easy-to-operate precision irrigation systems that deliver water and nutrient solution directly to the root zone of plants through controlled water flow. They are suitable for water-saving needs in small farmlands or resource-limited areas. Their core objective is to improve irrigation efficiency by minimizing water waste and human intervention, and they are especially suitable for arid regions or crop cultivation that requires meticulous management.

[0003] Current simple irrigation devices mainly consist of a water storage tank and drip irrigation heads. The water storage tank is erected in the farmland by a support frame. Water is stored in the water storage tank, and the water is discharged out through the drip irrigation heads by its own weight to achieve the purpose of drip irrigation. However, as the water in the water storage tank is gradually used up, its own weight gradually decreases, and the pressure of the droplets discharged from the drip irrigation heads will also decrease. In addition, the drip irrigation flow rate of the drip irrigation heads cannot be adjusted, making it difficult to meet the planting needs. Utility Model Content

[0004] This invention proposes a simple drip irrigation device that solves the problems of reduced internal pressure in the drip head and difficulty in adjusting the drip flow rate in the prior art.

[0005] The technical solution of this utility model is as follows: A simple drip irrigation device includes a water storage tank and a bracket set on the water storage tank; it also includes a sinking structure, a drip head and an adjustment component. The sinking structure is slidably disposed inside the water storage tank. The drip head is threadedly installed at the bottom output end of the water storage tank. The adjustment component is disposed inside the drip head and is used to adjust the drainage hole diameter of the drip head.

[0006] As a preferred embodiment of the simple drip irrigation device described in this utility model, the sinking structure includes a holding tray, a screw cap, and a weight block. The holding tray has a cavity inside and a water storage hole at the top. The screw cap is threaded onto the water storage hole.

[0007] In a preferred embodiment of the simple drip irrigation device described in this utility model, the adjusting component includes a fixed plate and an adjusting plate. The fixed plate is fixedly disposed inside the drip irrigation head and has multiple water passage holes arranged in a circular pattern with gradually increasing diameters. The adjusting plate is rotatably disposed on the fixed plate and has water passage holes.

[0008] In a preferred embodiment of the simple drip irrigation device described in this utility model, each of the water passage holes is provided with a spherical groove, and the bottom circumference of the adjusting plate is provided with multiple hemispherical structures, the number of which is one less than the number of water passage holes.

[0009] In a preferred embodiment of the simple drip irrigation device described in this utility model, a placement groove is provided at the top center of the fixed plate, and a spring is connected inside the placement groove, with the top of the spring connected to the bottom of the adjusting plate.

[0010] In a preferred embodiment of the simple drip irrigation device described in this utility model, an O-ring is fitted around the outer ring of the hemispherical structure.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figures 1-6 As shown, this embodiment proposes a simple drip irrigation device, including a water storage tank 1 and a bracket 2 mounted on the water storage tank 1; it also includes a sinking structure, a drip head 3, and an adjustment component. The sinking structure is slidably disposed inside the water storage tank 1, the drip head 3 is threadedly mounted on the bottom output end of the water storage tank 1, and the adjustment component is disposed inside the drip head 3 for adjusting the drainage hole diameter of the drip head 3. As the water volume inside the water storage tank 1 gradually decreases, the weight of the sinking structure provides water pressure to ensure stable drip irrigation operation. The alignment state of the water passage 10 is changed by a mechanical rotating structure to achieve flow control. The device is easy to operate. Through the dual adjustment of the sinking structure and the adjustment component, the drip irrigation frequency and flow rate can be adjusted according to the drip irrigation situation to adapt to the drip irrigation needs of different crops, making it more adaptable.

[0026] In this embodiment, the sinking structure includes a holding tray 4, a screw cap 5, and a weight block 6. The holding tray 4 has an internal cavity and a water storage hole at its top. The screw cap 5 is threaded onto the water storage hole. The weight block 6 is installed at the bottom of the holding tray 4. The weight block 6 is conical with its tip pointing downwards. The weight block 6 and its shape design ensure that the holding tray 4 can move linearly downwards along the inner wall of the water storage tank 1. A piston rubber ring 7 is provided on the outer circumference of the holding tray 4 to ensure the sliding seal between the holding tray 4 and the inner wall of the water storage tank 1. Water is stored in the holding tray 4 through the water storage hole. By changing the amount of water, the weight of the holding tray 4 can be adjusted, thereby adjusting the downward pressure on the water storage tank 1 and enhancing adaptability.

[0027] In this embodiment, the adjustment assembly includes a fixed disk 8 and an adjustment plate 9. The fixed disk 8 is fixedly disposed inside the drip head 3. The fixed disk 8 has multiple water passage holes 10 arranged in a circular pattern with gradually increasing diameters. The adjustment plate 9 is rotatably disposed on the fixed disk 8 and has water passage holes 11. Each water passage hole 10 has a spherical groove 12. The bottom circumference of the adjustment plate 9 has multiple hemispherical structures 13, the number of which is one less than the number of water passage holes 10. The top center of the fixed disk 8 has a placement groove 14, and a spring 15 is connected inside the placement groove 14. The top of the spring 15 is connected to the bottom of the adjustment plate 9. The end connection, through the tension of the spring 15, ensures that the hemispherical structure 13 can always stay in the corresponding spherical groove 12, thereby limiting the position of the rotating adjustment plate 9. Moreover, through the design of the hemispherical structure 13, it has a good arc surface, making the rotation smoother. The water passage hole 11 on the spherical groove 12 that is not embedded in the hemispherical structure 13 can let the water in the water storage tank 1 flow out from the bottom of the drip head 3. Thus, by rotating the adjustment plate 9 to different positions, the water passage hole 11 can be aligned with different water passage holes 10 to achieve flow rate adjustment. The spring 15 is provided with an anti-corrosion coating to improve the service life of the spring 15. The spring 15 can also be disassembled and replaced periodically. The diameter of the water passage hole 10 can also be marked on the side wall of the drip head 3 for easy selection.

[0028] It should be noted that the outer ring of the hemispherical structure 13 is fitted with an O-ring 19. Through the tension of the spring 15, the hemispherical structure 13 enters the corresponding spherical groove 12. The O-ring 19 can seal the gap between the hemispherical structure 13 and the spherical groove 12, ensuring that the water can only flow out from the adjusted water passage 10. The top of the adjusting plate 9 is connected to the adjusting rod 16. The adjustment of the water passage 10 is determined before crop drip irrigation. Therefore, the adjusting rod 16 can be rotated first to rotate the water passage 10, and then the drip irrigation head 3 can be rotated and installed at the bottom of the water storage tank 1. The bottom of the water storage tank 1 is provided with a valve 17 to facilitate the interception of water inside the water storage tank 1 when adjusting the water passage 10 by disassembling the drip irrigation head 3. The outer wall of the drip irrigation head 3 is provided with anti-slip protrusions to facilitate the rotation, disassembly and installation of the drip irrigation head 3.

[0029] This embodiment presents a simple drip irrigation device. In use, the entire device is first positioned at the location of the crop. Then, according to the type of crop and its water requirement, water is added to the holding tray 4, and the cap 5 is tightened. The holding tray 4 is then placed inside the water storage tank 1 along its axis. Before this, the corresponding diameter water passage 10 is selected, and the drip irrigation head 3 is rotated and installed at the bottom of the water storage tank 1. A sealing ring is fitted onto the drip irrigation head 3, and corresponding Teflon tape is wrapped around the external threads of the drip irrigation head 3 to maintain a tight seal. For batch drip irrigation, the pipe 18 can be first threaded into the bottom of the water storage tank 1, and then the drip irrigation head 3, after adjusting the flow rate, can be evenly installed on the pipe 18 for drip irrigation of crops in different locations. Figure 6 As shown.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
