Description

Technical Field

[0001] This utility model specifically relates to a watering device for strawberry seedling cultivation, belonging to the field of strawberry seedling watering technology. Background Technology

[0002] Drip irrigation systems are widely used in strawberry seedling cultivation. By slowly delivering water to the plant roots in droplets, it ensures precise water supply, which not only significantly reduces water waste but also effectively avoids root diseases caused by excessive soil moisture, thereby promoting healthy seedling growth and improving the overall survival rate.

[0003] During strawberry drip irrigation, inorganic salt crystals such as calcium carbonate, organic colloids, and insoluble fertilizer residues in the irrigation water and fertilizer solution can easily accumulate in the dripper channels over a long period of time, causing dripper blockage. This leads to a decrease in irrigation uniformity, resulting in drip leakage or uneven irrigation, which affects the normal growth of strawberry seedlings. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a watering device for strawberry seedling cultivation.

[0005] A watering device for strawberry seedling cultivation includes a main water supply pipe connected to multiple sets of branch water supply pipes. A first drip irrigation pipe and a second drip irrigation pipe are connected to each branch water supply pipe from high to low. Each of the first and second drip irrigation pipes has a drip irrigation head threaded to one end. A limiting ring is fixedly connected to each branch water supply pipe between the first and second drip irrigation pipes. A piston is slidably and sealingly connected to each branch water supply pipe between the first and second drip irrigation pipes. A first sliding rod is fixedly connected to one end of the piston, slidingly penetrating the interior of the branch water supply pipe. A spring is provided between the piston and the bottom end of the branch water supply pipe. A first strong magnetic plate is fixedly connected to the bottom end of the branch water supply pipe, and a second strong magnetic plate, magnetically attracted to the first strong magnetic plate, is correspondingly fixed to one end of the piston.

[0006] The first slide bar has a limiting block fixed to one end outside the water supply branch pipe, and the limiting block is coated with a fluorescent layer and a color developing layer in sequence.

[0007] A filter plate is fixedly connected to the top of the water supply branch pipe. A sleeve shaft is rotatably connected to the center of the filter plate. A second sliding rod is fixedly connected to one end of the piston, passing through the sleeve shaft. A spiral groove is opened on the second sliding rod. A slider that is slidably connected to the spiral groove is fixedly connected to the inner side of the sleeve shaft. A cleaning brush that contacts the filter plate is fixedly connected to the outer side of the sleeve shaft.

[0008] One end of the main water supply pipe is connected to a water delivery pipe, and the other end of the water delivery pipe is connected to a water tank. A pump is installed in the middle of the water delivery pipe, and a stirring rod is rotatably installed inside the water tank. A motor connected to the stirring rod is installed at the top of the water tank.

[0009] An arc-shaped filter screen is installed at one end of the water delivery pipe inside the water tank, and a scraper that contacts the arc-shaped filter screen is fixed to one end of the stirring rod.

[0010] The water tank is equipped with a feed inlet at the top and a water inlet pipe and flange on one side. Beneficial effects

[0011] After being distributed to the branch pipes through the main water supply pipe, the water is controlled by a piston to prioritize the discharge through the first drip irrigation pipe at the higher position. When the first drip irrigation pipe is blocked, the piston moves down under hydraulic pressure to overcome the spring force due to the accumulation of water flow. Two sets of strong magnetic plates lock the piston to the lower position of the second drip irrigation pipe, reducing flow fluctuations and allowing water to be discharged through the second drip irrigation pipe. This achieves automatic switching of the drip irrigation path, ensuring the continuity and stability of irrigation and avoiding water supply interruptions caused by blockages.

[0012] The arc-shaped filter screen can filter large particles of impurities in the water-fertilizer solution, and combined with the filter plate, it can further filter fine impurities, achieving a dual filtration effect and reducing the risk of drip head clogging. At the same time, the scraper automatically cleans the arc-shaped filter screen as the stirring rod rotates, and when the piston moves, the second slide rod, spiral groove, slider and sleeve shaft work together to drive the cleaning brush to automatically clean the filter plate, achieving a self-cleaning effect for both the arc-shaped filter screen and the filter plate.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 As shown, a watering device for strawberry seedling cultivation includes a main water supply pipe 1, with multiple sets of branch water supply pipes 2 connected to the main water supply pipe 1. A first drip irrigation pipe 3 and a second drip irrigation pipe 4 are connected to each branch water supply pipe 2 from high to low. One end of each of the first drip irrigation pipe 3 and the second drip irrigation pipe 4 is threaded with a drip irrigation head 5. A limiting ring 6 is fixedly connected to the branch water supply pipe 2 between the first drip irrigation pipe 3 and the second drip irrigation pipe 4. A piston 7 is slidably connected to the branch water supply pipe 2 between the first drip irrigation pipe 3 and the second drip irrigation pipe 4. A first sliding rod 8, which slides through the interior of the branch water supply pipe 2, is fixedly connected to one end of the piston 7. A spring 9 is provided between the piston 7 and the interior of the bottom end of the branch water supply pipe 2. A first strong magnetic plate 10 is fixedly connected to the interior of the bottom end of the branch water supply pipe 2. A second strong magnetic plate 11, which is magnetically attracted to the first strong magnetic plate 10, is correspondingly fixedly connected to one end of the piston 7.

[0017] The main water supply pipe 1 is the main water supply pipe for the entire drip irrigation system, responsible for delivering water to each branch pipe 2. The branch pipes 2 deliver water to the first drip irrigation pipe 3 or the second drip irrigation pipe 4. The first drip irrigation pipe 3 and the second drip irrigation pipe 4 are located at different heights on the branch pipes 2, and the water is delivered to the roots of the strawberry seedlings in a dripping form through the drip head 5. At the same time, the first drip irrigation pipe 3 and the second drip irrigation pipe 4 are slightly staggered to prevent the liquid dripped from the first drip irrigation pipe 3 from falling onto the second drip irrigation pipe 4. Under normal use and without blockage, the water source will only be discharged through the first drip irrigation pipe 3 under the cut-off action of the piston 7. The limiting ring 6 is used to limit the movement of the piston 7. The piston 7 is used to prevent excessive sliding from blocking the inlet of the first drip irrigation tube 3. The piston 7 is used to block the water source from entering the second drip irrigation tube 4. When the first drip irrigation tube 3 is completely blocked, the continuous accumulation of water will push the piston 7 to move down to the bottom of the water supply branch pipe 2, so that the water can be discharged through the second drip irrigation tube 4, ensuring the continuity of drip irrigation. The first slide bar 8 is used to improve the stability of the piston 7 sliding. The spring 9 provides elastic force so that the piston 7 remains in the default position when the first drip irrigation tube 3 is unobstructed. The first strong magnetic plate 10 and the second strong magnetic plate 11 are used to lock the position of the piston 7 so that the water can be discharged stably through the second drip irrigation tube 4.

[0018] Furthermore, a limiting block 12 is fixed to one end of the first sliding rod 8 located outside the water supply branch pipe 2. The limiting block 12 is coated with a fluorescent layer and a color-developing layer in sequence. The limiting block 12 is used to limit the sliding range of the first sliding rod 8 to prevent it from sliding completely into the water supply branch pipe 2. The fluorescent layer enables the limiting block 12 to fluoresce in low light or nighttime environments, improving visibility. The color-developing layer adopts a bright color design to further enhance the visual recognition of the limiting block 12. When a group of first drip irrigation pipes 3 becomes blocked, the first sliding rod 8 will push the limiting block 12 to move away from the water supply branch pipe 2. Through the combination of the fluorescent layer and the color-developing layer, personnel can quickly identify which group of first drip irrigation pipes 3 is blocked.

[0019] Furthermore, a filter plate 13 is fixedly connected to the top of the water supply branch pipe 2. A sleeve shaft 16 is rotatably connected to the center of the filter plate 13. A second sliding rod 14, which passes through the sleeve shaft 16, is fixedly connected to one end of the piston 7. A spiral groove 15 is provided on the second sliding rod 14. A slider 17, which is slidably connected to the spiral groove 15, is fixedly connected to the inner side of the sleeve shaft 16. A cleaning brush 18, which contacts the filter plate 13, is fixedly connected to the outer side of the sleeve shaft 16. The filter plate 13 is used to filter out fine impurities and particulate matter in the water entering the water supply branch pipe 2, reducing... These impurities clog the drip irrigation pipe and drip irrigation head 5. The sleeve shaft 16 is the rotating support shaft of the cleaning brush 18. By rotating, the cleaning brush 18 is driven to clean the filter plate 13, reducing the clogging of the filter plate 13 due to the accumulation of impurities. The second slide rod 14, the spiral groove 15 and the slider 17 work together in a coordinated manner, so that when the piston 7 moves up and down, the second slide rod 14 moves accordingly. Through the cooperation of the spiral groove 15 and the slider 17, the sleeve shaft 16 is driven to rotate, thereby driving the cleaning brush 18 to automatically clean the filter plate 13.

[0020] Furthermore, one end of the main water supply pipe 1 is connected to a water delivery pipe 19, and the other end of the water delivery pipe 19 is connected to a water tank 20. A pump 26 is installed in the middle of the water delivery pipe 19. A stirring rod 22 is rotatably installed inside the water tank 20, and a motor 21 connected to the stirring rod 22 is installed at the top of the water tank 20. The water delivery pipe 19 is a water source delivery pipe that transports water or fertigation solution from the water tank 20 to the main water supply pipe 1, thereby supplying the entire drip irrigation system. The water tank 20 is used to store irrigation water or prepared fertigation solution. The motor 21 is connected to the stirring rod 22 and drives the stirring rod 22 to rotate through electricity. The stirring rod 22 stirs the fertigation solution in the water tank 20 to maintain the uniformity of the solution. The pump 26 provides the power to transport water or fertigation solution from the water tank 20 through the water delivery pipe 19 to the main water supply pipe 1, ensuring that the water source can smoothly enter the drip irrigation system.

[0021] Furthermore, an arc-shaped filter screen 23 is installed at one end of the water supply pipe 19 inside the water tank 20, and a scraper 24 that contacts the arc-shaped filter screen 23 is fixedly connected to one end of the stirring rod 22. The arc-shaped filter screen 23 filters water or fertilizer solution before it enters the water supply pipe 19, intercepting large particles of impurities and reducing the wear and failure rate of the pump 26. The scraper 24 can move synchronously with the rotation of the stirring rod 22 to scrape and clean the surface of the arc-shaped filter screen 23, removing impurities and deposits attached to the arc-shaped filter screen 23.

[0022] Furthermore, a feed inlet 25 is installed at the top of the water tank 20, and a water inlet pipe and flange are installed on one side of the water tank 20; the feed inlet 25 can easily add solid or liquid fertilizer to the water tank 20, and the water inlet pipe and flange facilitate connection to an external water source.

[0023] Working steps: Connect an external water source through the inlet pipe and flange to replenish clean water into the water tank 20, ensuring sufficient water volume. Turn on the motor 21 to drive the stirring rod 22 to rotate within the water tank 20, thoroughly mixing the water and fertilizer to ensure uniform mixing of the solution. Before entering the water supply pipe 19, the solution is filtered through an arc-shaped filter screen 23 to intercept large particles and floating matter, preventing impurities from entering the system and clogging pipes and equipment. The scraper 24 is fixed to one end of the stirring rod 22. Synchronous rotation of the stirring rod 22 scrapes and cleans the arc-shaped filter screen 23, removing impurities and deposits adhering to it and keeping it unobstructed. The pump 26, located in the middle of the water delivery pipe 19, provides power to transport the filtered fertilizer solution through the water delivery pipe 19 to the main water supply pipe 1. The main water supply pipe 1 then evenly distributes the fertilizer solution to each branch water supply pipe 2. Next, the filter plate 13 filters out fine impurities and particles in the water entering the branch water supply pipes 2, achieving a double filtration effect. This ensures proper filtration during normal use without clogging. In the event of a blockage, spring 9 provides elastic force, keeping piston 7 in its default position when the first drip irrigation tube 3 is unobstructed. At this time, water is discharged only through the first drip irrigation tube 3. When the first drip irrigation tube 3 becomes completely blocked, the continuous accumulation of water pushes piston 7 downwards, overcoming the elastic force of spring 9, and moving it to the bottom of the water supply branch pipe 2, allowing water to be discharged through the second drip irrigation tube 4, ensuring continuous irrigation. When piston 7 moves to the bottom of the water supply branch pipe 2, the first strong magnetic plate 10 and the second strong magnetic plate 11 lock the position of piston 7 through magnetic attraction, ensuring a stable water flow. The water is discharged through the second drip tube 4. When the piston 7 moves, the second slide rod 14 moves accordingly. Through the cooperation of the spiral groove 15 and the slider 17, the sleeve shaft 16 is driven to rotate. The rotation of the sleeve shaft 16 drives the cleaning brush 18 to automatically clean the filter plate 13 and prevent the filter plate 13 from clogging. When a group of first drip tubes 3 is clogged, the first slide rod 8 will push the limit block 12 to move away from the water supply branch pipe 2. Through the combination of the fluorescent layer and the color developing layer, the staff can quickly identify and locate the clogged first drip tube 3, which is convenient for subsequent maintenance.
