Description

Technical Field

[0001] The utility model relates to the technical field of blueberry planting drip irrigation devices, in particular to an adjustable pressure-compensating dripper. Background Art

[0002] Drip irrigation is the preferred irrigation method for blueberry cultivation. This choice is based on several reasons, including the blueberry's specific water requirements, reducing pests and diseases, facilitating the movement of drip irrigation areas, and improving water resource efficiency.

[0003] Existing pressure-compensating drippers adjust pressure by changing the dripper's flow area, such as with an elastic diaphragm. When water pressure increases, the elastic diaphragm is squeezed, shrinking the outlet of the flow channel, reducing water pressure and thus maintaining a stable flow rate. However, in this technical solution, the position between the elastic diaphragm and the outlet of the flow channel is fixed, and therefore the adjustable pressure range is also fixed. When the water pressure exceeds the applicable range, the dripper needs to be replaced, and the pressure compensation range cannot be adjusted.

[0004] For example, an adjustable pressure-compensating dripper disclosed in Chinese patent CN211020360U has a base and a cap, which are connected to the cap by a threaded connection. The end of the cap is provided with a water inlet pipe, and a retaining plate is provided inside the cap. The retaining plate is connected to a spring at one end away from the water inlet pipe, and a rubber diaphragm is connected to the other end of the spring. The rubber diaphragm is provided with a spiral groove at one end away from the spring, and a stopper is provided in the spiral groove. The end of the base is provided with a water outlet pipe. A small hole is opened in the water pipe, and the socket at the water inlet pipe end of the dripper is aligned with the small hole. The dripper is inserted into the water pipe, and the water pipe is turned on. According to the water pressure, the base is rotated to adjust the distance between the base and the cap so that water drips evenly from the dripper.

[0005] However, when the pressure-compensating dripper used in the prior art is in use, the elastic diaphragm of the dripper is subjected to different pressures due to the different water pressures inside the dripper at the water inlet end and the distal end, which affects the water flow size and drip irrigation speed. Therefore, it is necessary to adjust the water pressure inside the dripper to ensure that the drip irrigation speed and water flow size are consistent.

[0006] For this reason, we urgently need to provide a kind of adjustable pressure compensation dripper. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-6 , the utility model provides a technical solution:

[0029] Example 1:

[0030] An adjustable pressure-compensating dripper comprises a plug connector 1, the top of the plug connector 1 is connected to a body structure, a pressure-bearing structure is installed at the bottom end of the body structure, and an adjustment structure is installed on the top of the pressure-bearing structure.

[0031] The adjustment structure includes an abutment unit and an adjustment unit. The abutment unit is mounted at the bottom of the adjustment unit. The abutment unit includes an adjustment plate 304. Sliders 305 are mounted in the middle of the left and right sides of the adjustment plate 304. Guide rails 306 are connected to the outer surfaces of the slides 305. Abutment rods 307 are mounted in the middle of the bottom surface of the adjustment plate 304, near the left and right ends. The adjustment unit includes a water outlet head 301. A water outlet pipe 302 is fixedly connected to the middle of the bottom surface of the water outlet head 301. A limit block 303 is fixedly mounted on the outer surface of the water outlet pipe 302, near the bottom end.

[0032] The outer surface of the limit block 303 is rotatably connected to the inner wall of the rotating groove opened on the inner wall of the circular hole in the middle of the adjustment plate 304, and the outer surface of the slider 305 is slidably connected to the inner wall of the convex groove opened in the middle of one side close to the two guide rails 306, and the interior of the water head 301 is connected to the interior of the water outlet pipe 302.

[0033] By setting the adjustment structure, the rotating water outlet head 301 drives the water outlet pipe 302 to rotate, so that the limit block 303 drives the adjustment plate 304 to rise and fall, and the abutment rod 307 is used to limit the height of the pressure plate 204, thereby adjusting the amount of water output, thereby ensuring the water volume and water flow rate of drip irrigation.

[0034] When it is necessary to adjust the drip irrigation water output and drip irrigation speed of the dripper, the water outlet head 301 is rotated to drive the water outlet pipe 302 to rotate, and the outer surface of the water outlet pipe 302 is connected to the fixed block 104 by thread, so as to adjust the length of the water outlet pipe 302 inside the adjustment chamber 102, and the limit block 303 is connected to the rotating groove inside the circular hole in the middle of the adjustment plate 304 by rotation, so that the limit block 303 drives the adjustment plate 304 to rise and fall. At the same time, when the adjustment plate 304 is raised and lowered, the slider 305 is used to slide inside the convex groove provided in the guide rail 306 to limit the lifting and lowering of the adjustment plate 304, so that the abutment rod 307 is installed at the bottom of the adjustment plate 304 to limit the displacement of the pressure plate 204, thereby ensuring that the water output and drip irrigation speed of the dripper at the water inlet end and the remote water end are consistent.

[0035] Example 2:

[0036] Based on the first embodiment, the main structure includes a water inlet hopper 101, with a regulating chamber 102 fixedly connected to the top of the water inlet hopper 101. A top cover 103 is fixedly mounted in the middle of the top surface of the regulating chamber 102, and a fixing block 104 is fixedly mounted on the top surface of the top cover 103. The four fixing blocks 104 are threadedly connected to the middle of the outer surface of the water outlet pipe 302 on the side closest to each other. The middle of the left and right inner walls of the regulating chamber 102 are fixedly connected to the two guide rails 306 on the side away from each other.

[0037] The pressure-bearing structure includes a cover 201, with a connecting pipe 202 mounted in the middle of its top surface. A spring 203 is mounted in the middle of its top surface, near the left and right ends. A pressure plate 204 is connected to the top of the spring 203, and a drain pipe 205 is fixedly mounted in the middle of its bottom surface. The outer surface of the cover 201 is fixedly connected to the top of the water inlet hopper 101. The end of the spring 203, away from the adjustment plate 304, is fixedly connected to the top of the cover 201. The outer surface of the drain pipe 205 is in sliding connection with the inside of the connecting pipe 202.

[0038] Through the arrangement of the main body structure and the pressure-bearing structure, utilizing the spring 203 installed on the top of the sealing cover 201 and the connection between the spring 203 and the pressure plate 204, the contraction tension of the spring 203 can be utilized to cause the pressure plate 204 to seal the connecting pipe 202. Under a certain water pressure, the water pressure is utilized to push the pressure plate 204 and the leakage pipe 205 upward, thereby enabling the dripper to perform drip irrigation under a certain water pressure.

[0039] When using the pressure structure to discharge water, the plug connector 1 is inserted into the installation hole opened on the surface of the water delivery pipe, so that the water flows into the water inlet bucket 101 through the plug connector 1, and then is transported through the connecting pipe 202. The pressure plate 204 is pushed by the water pressure, so that the pressure plate 204 drives the spring 203 to stretch. The force of the spring 203 stretching and deforming ensures that the pressure plate 204 drives the leakage pipe 205 to rise under a certain water pressure, so that water is discharged through the water outlet hole opened on the outer surface of the leakage pipe 205, so that the dripper can perform drip irrigation under a certain water pressure.
