Description

Technical Field

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

[0002] Drip irrigation equipment is a highly efficient and water-saving irrigation system that uses a low-pressure pipeline system and drippers installed on capillary tubes to deliver water and nutrients evenly and accurately into the soil around the crop root zone at a relatively small flow rate.

[0003] Existing drip irrigation equipment often uses perforations in the pipe or a single dripper structure. Controlling drip irrigation efficiency is usually achieved by controlling the efficiency of the water pump. However, for longer pipes, controlling the dripping efficiency is not precise enough. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a drip irrigation dripper device that can control the drip irrigation efficiency, in view of the shortcomings mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a drip irrigation device, including a main pipe, with an inlet connection end and an outlet connection end at both ends of the main pipe, and a drip irrigation structure at the bottom of the main pipe, wherein the drip irrigation structure is provided with an inlet section, an adjustment section and an outlet section connected to each other from top to bottom.

[0006] The regulating section is equipped with an regulating structure, and the regulating structure has multiple outlets of different sizes in the middle. The outlets are connected to the water outlet section. The main pipe is equipped with a regulating motor at the top, and the regulating motor has a rotating shaft at the bottom power end. The rotating shaft extends into the regulating structure and is equipped with a regulating block. The regulating block is equipped with a water guide groove that can connect the water inlet section and the water outlet.

[0007] Furthermore, the inner side of the adjustment structure is provided with a first sealing ring and a second sealing ring above and below the water outlet, respectively, which can ensure the sealing operation.

[0008] Furthermore, a third sealing ring is provided on the inner side of the adjustment structure below the water guide groove, which can further ensure the sealing operation.

[0009] Furthermore, the top of the main pipe is equipped with a sealed bearing structure that works in conjunction with the adjusting motor and the rotating shaft to ensure the sealing operation of the rotating shaft.

[0010] Furthermore, the main pipeline is equipped with a first filter screen structure and a second filter screen structure at the inlet and outlet connection ends, respectively, to prevent larger impurities from entering the operation.

[0011] The advantages of this drip irrigation dripper device compared with the prior art are as follows: This device, through the setting of an inlet section, an adjustment section and an outlet section, and the multiple outlets set by the internal adjustment structure in conjunction with the water guide groove of the adjustment block, can adjust the dripping rate as needed.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] Combined with appendix Figure 1-3 A drip irrigation device includes a main pipe 1, with an inlet connection 2 and an outlet connection 3 at both ends of the main pipe 1. A drip irrigation structure 4 is provided at the bottom of the main pipe 1. The drip irrigation structure 4 is provided with an inlet section 5, an adjustment section 6 and an outlet section 7 that are interconnected from top to bottom.

[0018] The regulating section 6 is equipped with an regulating structure 8. The regulating structure 8 has multiple outlets 9 of different sizes in the middle. The specific size of the outlets 9 can be set according to the needs of the plant. The outlets 9 are connected to the water outlet section 7. The main pipe 1 is equipped with a regulating motor 10 at the top. The regulating motor 10 has a rotating shaft 11 at the bottom power end. The main pipe 1 is equipped with a sealed bearing structure 19 that cooperates with the regulating motor 10 and the rotating shaft 11. The sealed bearing structure 19 can prevent water in the main pipe 1 from overflowing through the connection end of the rotating shaft 11. The rotating shaft 11 extends into the regulating structure 8 and is equipped with an regulating block 12. The regulating block 12 is equipped with a water guide groove 16 that can connect the water inlet section 5 and the outlets 9. That is, in actual operation, the regulating motor 10 drives the rotating shaft 11 to rotate, so that the water guide groove 16 of the regulating block 12 moves to the position of the outlets 9 of different sizes, thus completing the water output adjustment operation of the drip irrigation structure 4.

[0019] The inner side of the adjustment structure 8 is provided with a first sealing ring 13 and a second sealing ring 14 above and below the water outlet 9, respectively. The inner side of the adjustment structure 8 is provided with a third sealing ring 15 below the water guide groove 16. The arrangement of the first sealing ring 13, the second sealing ring 14 and the third sealing ring 15 from top to bottom can prevent water from overflowing through the gaps and other water outlets 9 when water is discharged from one of the water outlets 9.

[0020] The main pipe 1 is equipped with a first filter structure 17 and a second filter structure 18 at the inlet connection end 2 and the outlet connection end 3, respectively. Since there are usually multiple dripper devices, only the main pipe 1 of the first dripper device is equipped with the first filter structure 17, and the main pipe 1 of the last dripper device is equipped with the second filter structure 18. The first filter structure 17 and the second filter structure 18 are set to prevent large foreign objects from entering the equipment, which could cause blockage of the outlet 9 or damage to the sealing ring. If the first filter structure 17 is blocked, it can be flushed by backwashing. During backwashing, the second filter structure 18 will perform the filtering function.

[0021] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
