An adjustable drip irrigation device for kale cultivation

Abstract

This utility model discloses an adjustable drip irrigation device for kale cultivation, including a water tank, a water pump, and branch pipes. The water tank and the water pump are connected by water pipes. A main valve is connected to the side of the water pump away from the water tank via a water pipe. A tee pipe is connected to the side of the main valve away from the water pump via a water pipe. Each branch pipe is connected to both ends of the tee pipe away from the main valve. Several connecting pipes are equidistantly connected to the bottom ends of both branch pipes. A drip irrigation pipe is movably connected to the outer surface of the bottom end of each connecting pipe. The advantage of this utility model is that the movable blocks on both sides inside the drip irrigation pipe wedge with the driving rings on the outer surface of the connecting pipes, thereby pushing the movable blocks on both sides to move the baffles closer or further apart. When the baffles move further apart, the current drip irrigation flow rate is increased; when the baffles move closer together, the current drip irrigation flow rate is decreased, avoiding the formation of grooves in the water flow due to excessive drip volume.

Description

Technical Field

[0001] This utility model relates to the field of kale cultivation technology, specifically to an adjustable drip irrigation device for kale cultivation. Background Technology

[0002] Kale is a low-calorie, high-nutrient cruciferous vegetable, rich in dietary fiber, vitamin C, vitamin K, and antioxidants. It may help regulate intestinal function, enhance immunity, and protect cardiovascular health. Kale cultivation usually requires the use of drip irrigation systems. Drip irrigation systems deliver water precisely to the roots of the crop through a pipeline system, monitor soil moisture in real time, prevent waterlogging and root rot, and save water and labor.

[0003] Existing drip irrigation devices for kale cultivation can only adjust and control the overall drip irrigation volume, but cannot adjust and control it individually according to the different growth needs of different kale varieties. This can easily lead to excessive drip irrigation in some areas, causing the formation of channels and leakage of drip irrigation liquid, thus affecting the overall drip irrigation effect. Therefore, this does not meet the current needs. To address this, we propose an adjustable drip irrigation device for kale cultivation. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable drip irrigation device for kale cultivation, in order to solve the problem mentioned in the background art that the existing drip irrigation devices for kale cultivation can only adjust and control the overall drip irrigation water volume, but cannot adjust and control it individually according to the different growth needs of different kale plants. This can easily lead to excessive drip irrigation volume in some areas, causing the formation of gullies at the water flow points and resulting in the leakage of drip irrigation liquid, which in turn affects the overall drip irrigation effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable drip irrigation device for kale cultivation, comprising a water tank, a water pump, and a distribution pipe. The water tank and the water pump are connected by a water pipe. A main valve is connected to the side of the water pump away from the water tank via a water pipe. A tee pipe is connected to the side of the main valve away from the water pump via a water pipe. Each distribution pipe is connected to both ends of the tee pipe away from the main valve. Several connecting pipes are equidistantly connected to the bottom ends of both distribution pipes. A drip irrigation pipe is movably connected to the outer surface of the bottom end of each connecting pipe.

[0006] Preferably, each of the connecting tubes has a threaded groove on its outer surface near the upper end, and an internal threaded ring that is threadedly connected to the threaded groove is fixedly connected to the inner side of the drip irrigation tube near the upper end.

[0007] Preferably, a drive ring is fixedly connected to the outer surface of the connecting pipe near the bottom end, and the drive ring is arranged in an inverted cone shape. Above the drive ring and located on the inner wall of the drip irrigation pipe, a limiting plate is fixedly connected in an annular shape.

[0008] Preferably, grooves are provided on both sides below the limiting plate and on the inner wall of the drip irrigation pipe. Fixing sleeves are fixedly connected inside the grooves on both sides. A connecting rod extending through to the outside of the fixing sleeve is slidably connected inside the two fixing sleeves on the side that is close to each other. A spring is fixedly connected between one side of the connecting rod and the inside of the fixing sleeve.

[0009] Preferably, the connecting rod extends through to one end of the fixed sleeve and is fixedly connected to a movable block. The two movable blocks are both inclined on the side that is close to each other and are wedged with the outer surface of the drive ring.

[0010] Preferably, baffles are fixedly connected to the bottom ends of the two movable blocks on the side that are close to each other.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model opens the main valve and starts the water pump to transport the water inside the water tank through the water pipe to the two side branch pipes. Then the branch pipes transport the water through each connecting pipe and then through the drip irrigation pipe to drip irrigate the kale.

[0013] 2. This utility model utilizes the reverse rotation of the drip irrigation tube to cause the internal threaded ring on the inner side of the upper end of the drip irrigation tube to rotate into the threaded groove on the outer surface of the connecting tube. This causes the drip irrigation tube to move towards the side closer to the branch pipe. As the drip irrigation tube moves upward, the movable blocks on both sides inside the drip irrigation tube engage with the drive ring on the outer surface of the connecting tube, thereby pushing the movable blocks on both sides to move the baffles away from each other and compressing the spring. This increases the opening between the baffles on both sides, thus adjusting and increasing the current drip irrigation flow rate. When the drip irrigation tube is rotated clockwise, it moves away from the branch pipe. Then, through the wedging with the drive ring on the outer surface of the connecting tube and under the elastic force of the spring, it pushes the baffles on both sides closer to each other, thereby reducing the current drip irrigation flow rate and preventing excessive drip volume from forming grooves at the water flow point, causing the drip irrigation liquid to overflow.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figure 1 As shown, one embodiment of this utility model is provided: an adjustable drip irrigation device for kale cultivation, including a water tank 1, a water pump 2, and a diversion pipe 6. The water tank 1 and the water pump 2 are connected by a water pipe 3. A main valve 4 is connected to the side of the water pump 2 away from the water tank 1 through the water pipe 3. A tee pipe 5 is connected to the side of the main valve 4 away from the water pump 2 through the water pipe 3. The diversion pipes 6 are all connected to the two ends of the tee pipe 5 away from the main valve 4. Several connecting pipes 7 are connected to the bottom ends of the two diversion pipes 6 at equal intervals. A drip irrigation pipe 8 is movably connected to the outer surface of the bottom end of each connecting pipe 7.

[0021] As a preferred technical solution in this embodiment, such as Figure 2 and Figure 3 As shown, each connecting pipe 7 has a threaded groove 701 on its outer surface near the upper end. The inner side of the drip irrigation pipe 8 near the upper end is fixedly connected to an internal threaded ring 9 that is threaded to the threaded groove 701. The outer surface of the connecting pipe 7 near the bottom end is fixedly connected to a driving ring 10, which is in an inverted conical shape. Above the driving ring 10 and on the inner wall of the drip irrigation pipe 8, a limiting plate 16 is fixedly connected in an annular shape.

[0022] In this embodiment, by rotating the drip irrigation pipe 8, the inner threaded ring 9 on the inner side of the upper end of the drip irrigation pipe 8 is screwed onto the threaded groove 701 on the outer surface of the connecting pipe 7, thereby causing the drip irrigation pipe 8 to move toward or away from the diversion pipe 6. Furthermore, the setting of the limiting plate 16 can prevent the drip irrigation pipe 8 from rotating and disengaging from the connecting pipe 7.

[0023] As a preferred technical solution in this embodiment, such as Figure 3 and Figure 4As shown, grooves 801 are provided on both sides below the limiting plate 16 and on the inner wall of the drip irrigation pipe 8. Fixing sleeves 11 are fixedly connected inside the grooves 801 on both sides. Connecting rods 13 extending through to the outside of the fixing sleeves 11 are slidably connected inside the side of the two fixing sleeves 11 that are close to each other. A spring 12 is fixedly connected between one side of the connecting rod 13 and the inside of the fixing sleeve 11. A movable block 14 is fixedly connected to one end of the connecting rod 13 that extends through to the outside of the fixing sleeve 11. The side of the two movable blocks 14 that are close to each other is set with an incline and is wedged into the outer surface of the drive ring 10. A baffle 15 is fixedly connected to the bottom end of the side of the two movable blocks 14 that are close to each other.

[0024] In this embodiment, the movable blocks 14 on both sides inside the drip irrigation pipe 8 wedge with the driving ring 10 on the outer surface of the connecting pipe 7, thereby pushing the movable blocks 14 on both sides to move the baffles 15 closer or further apart. The baffles 15 on both sides move further apart, thereby increasing the current dripping flow of the drip irrigation pipe 8. The baffles 15 on both sides move closer together, thereby reducing the current dripping flow of the drip irrigation pipe 8, avoiding the formation of grooves at the water flow point due to excessive dripping volume, and causing the dripping liquid to overflow.

[0025] When using the drip irrigation system for kale cultivation, the main valve 4 is opened and the water pump 2 is started to transport water from the water tank 1 through the water pipe 3 to the two branch pipes 6 on both sides. Then, the branch pipes 6 pass the water through each connecting pipe 7 and then through the drip irrigation pipe 8 to irrigate the kale. By rotating the drip irrigation pipe 8 in the reverse direction, the inner threaded ring 9 on the inner side of the upper end of the drip irrigation pipe 8 rotates into the threaded groove 701 on the outer surface of the connecting pipe 7, thereby moving the drip irrigation pipe 8 towards the side closer to the branch pipe 6. As the drip irrigation pipe 8 moves upward, the movable blocks 14 on both sides inside the drip irrigation pipe 8 drive the pipes on the outer surface of the connecting pipe 7. The wedging of the ring 10 pushes the movable blocks 14 on both sides to move the baffles 15 away from each other and compresses the spring 12, increasing the opening between the baffles 15 on both sides. This allows for adjustment and increases in the current drip flow rate of the drip irrigation pipe 8. When the drip irrigation pipe 8 is rotated clockwise, it moves away from the diversion pipe 6. This causes the driving ring 10 to wed with the outer surface of the connecting pipe 7, and under the elastic force of the spring 12, pushes the baffles 15 on both sides closer together, thereby reducing the current drip flow rate of the drip irrigation pipe 8. This prevents excessive drip volume from forming grooves at the water flow point and causing the drip irrigation liquid to overflow.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
