Description

Technical Field

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

[0002] Blueberries are a fruit crop that prefers acidic soil and ample water. They have shallow roots and are sensitive to changes in soil moisture. Their water requirements vary at different growth stages. To ensure fruit quality and yield, blueberry cultivation usually requires precise management of soil moisture and maintaining a suitable moisture level around the roots. In modern greenhouse or open-field cultivation, proper control of irrigation amount and method can effectively promote plant growth, flowering, fruiting, and fruit enlargement.

[0003] During long-term use, existing drip irrigation systems tend to accumulate scale and impurities in the water delivery pipes, especially in the bends of the inner walls. This usually requires disassembly and manual cleaning, which is cumbersome and time-consuming. There is a lack of simple self-cleaning structures that can automatically clean the pipes during use. At the same time, because blueberry plant roots have a strong tendency to grow towards water, they will actively extend into the water delivery or outlet pipes along the direction of the dripper. Existing drip irrigation systems lack effective turbine water intake structures, which cannot effectively restrict root growth in the drip irrigation pipes, easily leading to pipe blockage. This affects the uniformity of irrigation and the normal water absorption of blueberry plants.

[0004] Therefore, this utility model proposes a drip irrigation device for blueberry plant cultivation. Utility Model Content

[0005] Therefore, in order to overcome the problems of existing drip irrigation devices, such as the accumulation of scale and impurities in the water pipes, especially in bends, which require disassembly and manual cleaning and lack of simple self-cleaning function, and the fact that blueberry roots can easily extend into the pipes along the drippers, the lack of a turbine water intake structure in existing devices can not effectively restrict root growth, easily leading to pipe blockage and affecting the uniformity of irrigation and the plant's water absorption.

[0006] The technical solution of this utility model is as follows: a drip irrigation device for blueberry plant cultivation, comprising a water storage tank, a water outlet pipe, and a turbine gate; a water supply pipe is fixedly connected inside the water storage tank, and a connecting shell is fixedly connected to the outer wall of the water supply pipe, the connecting shell being located away from the water storage tank; the water outlet pipe is fixedly connected to the end of the water supply pipe away from the water storage tank, and a dripper is flanged to the end of the water outlet pipe away from the water supply pipe; the turbine gate is rotatably connected to the inner wall of the water supply pipe, and the turbine gate is located near the connecting shell.

[0007] Preferably, the water supply pipe and the water outlet pipe are an integrated structure, the water outlet pipe is located near the connecting shell, and the dripper is an hourglass-shaped structure.

[0008] Preferably, a limiting block is fixedly connected to the outer side wall of the connecting shell, the limiting block is symmetrically installed on the side of the connecting shell, a limiting gear is movably connected to the outer side wall of the connecting shell, the limiting block is engaged with the outer side wall of the limiting gear, a rotating ring is fixedly connected to the side of the limiting gear away from the connecting shell, the rotating ring is located near the outer side wall of the limiting gear, and a return spring is fixedly connected to the side of the limiting gear away from the connecting shell, the return spring is symmetrically installed near the rotating ring.

[0009] Preferably, the connecting shell has a slidingly connected locking block inside. The locking blocks are symmetrically installed near the limiting gear. A limiting rod is fixedly connected to the end of the locking block away from the limiting gear. The limiting rod is symmetrically installed near both sides of the locking block. The limiting rod is slidably connected inside the connecting shell. A storage spring is sleeved on the outside of the limiting rod. One end of the storage spring is fixedly connected inside the connecting shell, and the other end of the storage spring is fixedly connected to the end of the locking block near the limiting rod.

[0010] Preferably, a connecting plate is fixedly connected to the end of the dripper near the water outlet pipe, and a fixing plate is connected to the flange on the side of the connecting plate away from the dripper. The fixing plate is fixedly connected to the end of the water outlet pipe near the dripper.

[0011] Preferably, a rotating shaft is fixedly connected inside the turbine gate, the rotating shaft is rotatably connected inside the water supply pipe and the connecting shell, the rotating shaft passes through the water supply pipe, the limiting gear is engaged with the outer side wall of the rotating shaft, one end of the rotating shaft is fixedly connected to a rotating disk, the rotating ring is slidably connected to the outer side wall of the rotating disk, and the end of the return spring away from the limiting gear is fixedly connected to the inner side of the rotating disk.

[0012] Preferably, a limiting ratchet is fixedly connected to the other end of the rotating shaft. The limiting ratchet is rotatably connected inside the connecting housing. A limiting pawl engages on the outer side wall of the limiting ratchet, and the limiting pawl is rotatably connected inside the connecting housing.

[0013] The beneficial effects of this utility model are: 1. When drip irrigation is needed for the external blueberry plants, pull the rotating ring to move the limiting gear along the rotation axis towards the rotating disk, gradually disengaging from the two sets of limiting blocks. At this time, the rotating ring moves outward along the outer wall of the rotating disk. After the limiting gear is completely disengaged, the storage spring pushes the locking block to move towards the limiting gear, locking between the limiting gear and the connecting shell, thus longitudinally limiting the limiting gear and releasing the restriction on the rotating shaft. At this time, the rotating shaft can rotate freely, and the water in the water tank flows through the water delivery pipe, turbine gate and water outlet pipe, and finally drips slowly into the soil through the dripper to achieve automatic drip irrigation for the blueberry plants. 2. During drip irrigation, the water flow in the water pipe drives the turbine gate to rotate, which in turn drives the rotating shaft to rotate synchronously. This causes the limiting ratchet to rotate synchronously within the connecting housing. The limiting pawl prevents the limiting ratchet and rotating shaft from reversing, ensuring that the turbine gate rotates in a single direction and preventing plant roots from penetrating deep into the water pipe. At the same time, the scraper on the turbine gate fits tightly against the inner wall of the water pipe, continuously scraping away scale and impurities at the bends of the water pipe and outlet pipe during rotation. This achieves a simple self-cleaning function for the device, preventing pipe blockage, maintaining smooth water flow, and thus avoiding affecting the uniformity of irrigation and the normal water absorption of the blueberry plants. 3. When drip irrigation needs to be stopped, pull the two sets of locking blocks to disengage from the limiting gear. The reset spring pushes the limiting gear along the rotating shaft and re-fits with the outer wall of the connecting shell. The limiting block is locked onto the outer wall of the limiting gear again, restricting the rotation of the limiting gear and the rotating shaft. At this time, the turbine gate is forced to stop rotating, and the scraper closes the water flow channel, which acts as a valve closure, thereby stopping drip irrigation. Attached Figure Description

[0020] Please see Figures 1-8 This utility model provides a technical solution: a drip irrigation device for blueberry plant cultivation, including a water storage tank 1, a water outlet pipe 4, and a turbine gate 6; a water supply pipe 2 is fixedly connected inside the water storage tank 1, and a connecting shell 3 is fixedly connected to the outer wall of the water supply pipe 2, the connecting shell 3 being located away from the water storage tank 1; the water outlet pipe 4 is fixedly connected to the end of the water supply pipe 2 away from the water storage tank 1, and a dripper 5 is flanged to the end of the water outlet pipe 4 away from the water supply pipe 2; the turbine gate 6 is rotatably connected to the inner wall of the water supply pipe 2, and the turbine gate 6 is located near the connecting shell 3.

[0021] The water supply pipe 2 and the water outlet pipe 4 are integrated structures. The water outlet pipe 4 is located near the connecting shell 3. The dripper 5 has an hourglass-shaped structure. The arrangement of the water outlet pipe 4 near the connecting shell 3 helps to shorten the water flow path, improve water pressure transmission efficiency, and make drip irrigation more stable. The hourglass-shaped dripper 5 can form a uniform pressure reduction and diversion effect when the water flows through it, making the dripping speed more constant. This ensures that the roots of the blueberry plants receive a continuous, fine, and stable water supply, improving irrigation uniformity and water use efficiency.

[0022] A limiting block 301 is fixedly connected to the outer wall of the connecting shell 3. The limiting block 301 is symmetrically installed on the side of the connecting shell 3. A limiting gear 302 is movably connected to the outer wall of the connecting shell 3. The limiting block 301 is engaged with the outer wall of the limiting gear 302. A rotating ring 303 is fixedly connected to the side of the limiting gear 302 away from the connecting shell 3. The rotating ring 303 is located near the outer wall of the limiting gear 302. A return spring 304 is fixedly connected to the side of the limiting gear 302 away from the connecting shell 3. The return spring 304 is symmetrically installed near the rotating ring 303. The return spring 304 can automatically push the limiting gear 302 back to the initial position after the external force is released, so as to achieve automatic reset and avoid repeated manual adjustment.

[0023] Inside the connecting shell 3, there is a sliding connection of a locking block 305. The locking blocks 305 are symmetrically installed near the limiting gear 302. The end of the locking block 305 away from the limiting gear 302 is fixedly connected to a limiting rod 306. The limiting rods 306 are symmetrically installed near both sides of the locking block 305. The limiting rods 306 are slidably connected inside the connecting shell 3. A storage spring 307 is sleeved on the outside of the limiting rod 306. One end of the storage spring 307 is fixedly connected inside the connecting shell 3, and the other end of the storage spring 307 is fixedly connected to the end of the locking block 305 near the limiting rod 306. The symmetrical arrangement of the limiting rods 306 ensures that the locking block 305 is subjected to balanced force and avoids the locking block 305 and the storage spring 307 from shifting or jamming during movement.

[0024] A connecting plate 501 is fixedly connected to one end of the dripper 5 near the water outlet pipe 4. A fixing plate 502 is connected to the flange on the side of the connecting plate 501 away from the dripper 5. The fixing plate 502 is fixedly connected to the end of the water outlet pipe 4 near the dripper 5. The flange connection between the connecting plate 501 and the fixing plate 502 facilitates disassembly and maintenance. The dripper 5 can be replaced or cleaned without affecting the overall water supply structure, thus improving the maintainability and service life of the device.

[0025] A rotating shaft 601 is fixedly connected inside the turbine gate 6. The rotating shaft 601 is rotatably connected inside the water supply pipe 2 and the connecting shell 3. The rotating shaft 601 passes through the water supply pipe 2. The limiting gear 302 is engaged with the outer wall of the rotating shaft 601. One end of the rotating shaft 601 is fixedly connected to the rotating disk 602. The rotating ring 303 is slidably connected to the outer wall of the rotating disk 602. The end of the return spring 304 away from the limiting gear 302 is fixedly connected to the inner side of the rotating disk 602. When water flows through, it can drive the turbine gate 6 to rotate, thereby driving the rotating shaft 601 to rotate synchronously, so that the limiting gear 302 and the rotating disk 602 work together to form a stable power transmission relationship.

[0026] The other end of the rotating shaft 601 is fixedly connected to a limiting ratchet 603, which is rotatably connected inside the connecting shell 3. A limiting pawl 604 engages on the outer wall of the limiting ratchet 603, which is rotatably connected inside the connecting shell 3. The limiting pawl 604 can prevent the limiting ratchet 603 and the rotating shaft 601 from reversing, effectively ensuring the stability of the water flow direction and preventing backflow of water and the blueberry plant roots from entering the water supply pipe 2.

[0027] Working principle: See Figures 1-5 As shown, when the device is ready to be used, first, place the water tank 1 next to the external blueberry plant and inject drip irrigation water into it. Then, insert the dripper 5 into the soil near the plant roots so that the connecting plate 501 and the fixing plate 502 are kept on the soil surface, thus completing the installation preparation of the device. See Figures 3-8 As shown, when drip irrigation is needed for the external blueberry plants, first, grasp and apply external force to pull the rotating ring 303, causing the limiting gear 302 to overcome the elastic force of the return spring 304 and move along the rotating shaft 601 towards the rotating disk 602, gradually disengaging from the engagement of the two sets of limiting blocks 301. At this time, the rotating ring 303 moves outward along the outer wall of the rotating disk 602. When the limiting gear 302 is completely disengaged, the storage spring 307 releases its elastic force, pushing the locking block 305 towards the limiting gear 302. During this process, the limiting rod 306 guides the locking block 305 to prevent the energy storage spring 307 from shaking. Then, the locking block 305 engages between the limiting gear 302 and the connecting shell 3, longitudinally limiting the limiting gear 302 and releasing the restriction on the rotating shaft 601. At this time, the rotating shaft 601 can rotate freely. The water in the water storage tank 1 flows through the water supply pipe 2, the turbine gate 6 and the water outlet pipe 4, and finally, it slowly drips into the soil through the dripper 5 under the action of gravity, realizing automatic drip irrigation of the blueberry plants. See Figures 3-8As shown, during drip irrigation, the water flow in the water pipe 2 drives the turbine gate 6 to rotate, which in turn drives the rotating shaft 601 to rotate synchronously, causing the limiting ratchet 603 to rotate synchronously in the connecting shell 3. Since the limiting pawl 604 meshes with the limiting ratchet 603, it can prevent the limiting ratchet 603 and the rotating shaft 601 from reversing, ensuring that the turbine gate 6 rotates in a single direction. At the same time, the scraper on the turbine gate 6 is in close contact with the inner wall of the water pipe 2, and continuously scrapes away the scale and impurities at the bends of the water pipe 2 and the outlet pipe 4 during the rotation process, realizing the simple self-cleaning function of the device. See Figures 3-8 As shown, when drip irrigation needs to be stopped, first, pinch and apply external force to pull the two sets of locking blocks 305, so that they overcome the elastic force of the storage spring 307 and disengage from the limiting gear 302. Under the elastic force of the return spring 304, the limiting gear 302 moves along the rotating shaft 601 towards the connecting shell 3 and re-fits with the outer wall of the connecting shell 3. The limiting block 301 is locked onto the outer wall of the limiting gear 302 again, restricting the rotation of the limiting gear 302 and the rotating shaft 601. At this time, the turbine gate 6 is forced to stop rotating, and the scraper closes the water flow channel, thereby stopping drip irrigation.

[0028] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
