[0003] Traditional seedling water exchange methods, such as using filter drums or fixed mesh cages, have many drawbacks. Because of the limited filtration area of ​​the filter drum screen, the strong suction during siphon pumping can easily cause seedlings to adhere to the screen. Prolonged adhesion can cause irreversible damage to the seedlings, even leading to death, greatly affecting the survival rate and yield of seedlings. Utility Model Content

[0004] The purpose of this invention is to provide a water exchange screen box that is easy to adjust. The motor drives the agitator rotating column to rotate the agitator plate, which effectively agitates the water, prevents seedlings from adsorbing and settling, and assists the water pump to enhance the pumping power of the siphon outlet pipe, thereby improving the water circulation efficiency. The pumping pipe directionally extracts the agitated water. With the detachable flexible filter cover, it can prevent seedlings and impurities from clogging the pipe, and is easy to clean and replace, ensuring smooth water pumping and improving the overall stability and controllability of the seedling environment.

[0005] To achieve the above objectives, a water exchange screen box with an easily adjustable screen is provided, comprising: a filter tank, a cover plate fixedly connected to the upper surface of the filter tank, a motor and a siphon outlet pipe fixedly connected to the upper surface of the cover plate, a disturbance rotating column fixedly connected to the output end of the motor, several disturbance plates fixedly connected to the outer surface of the disturbance rotating column, an auxiliary water pump provided on the outer surface of the siphon outlet pipe, a suction pipe fixedly connected to the outer surface of the siphon outlet pipe, and a flexible filter cover detachably connected to the lower surface of the suction pipe. This design filters impurities to prevent clogging and is detachable for easy cleaning and replacement.

[0006] According to the aforementioned water-changing screen box and filter tank with easily adjustable screen, a cover plate is fixedly connected to the upper surface of the filter tank.

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Reference Figure 1-4 This utility model provides a water exchange screen box with an adjustable screen, comprising: a filter tank 1, a cover plate 2 fixedly connected to the upper surface of the filter tank 1, the cover plate 2 providing a sealed protection for the filter tank 1 and providing a stable mounting base for upper components such as a motor 4 and a siphon outlet pipe 5; a motor 4 and a siphon outlet pipe 5 fixedly connected to the upper surface of the cover plate 2, the motor 4 providing a power source for the disturbance structure, and the siphon outlet pipe 5 serving as the main channel for water extraction; the arrangement of these two components on the cover plate 2 ensures the coordinated operation of water circulation and disturbance action; a disturbance rotation column 7 fixedly connected to the output end of the motor 4, the motor 4 driving the disturbance rotation column 7 to rotate through the output end, transmitting power to subsequent disturbance components; and the disturbance rotation column 7... Several disturbance plates 3 are fixedly connected to the outer surface of the moving column 7. When the moving column 7 rotates, it drives the disturbance plates 3 to rotate synchronously, which agitates the water to prevent seedlings from adsorbing and settling. An auxiliary water pump 6 is installed on the outer surface of the siphon outlet pipe 5. The auxiliary water pump 6 enhances the water flow dynamics in the siphon outlet pipe 5 and improves the water extraction efficiency. A water pumping pipe 11 is fixedly connected to the outer surface of the siphon outlet pipe 5. The water pumping pipe 11 guides the water in the inner filter cylinder 9 into the siphon outlet pipe 5 to achieve directional water pumping. A flexible filter cover 13 is detachably connected to the lower surface of the water pumping pipe 11. The flexible filter cover 13 filters the water entering the water pumping pipe 11 to prevent seedlings or impurities from clogging the pipe. The detachable design makes it easy to clean and replace.

[0018] The water suction pipe 11 is located above the disturbance plate 3. This arrangement allows the water agitated by the disturbance plate 3 to be drawn more smoothly by the water suction pipe 11, reducing dead zones in the water flow. The number of water suction pipes 11 corresponds to the number of disturbance plates 3, ensuring that each disturbance area has a corresponding water suction channel, improving the uniformity of the overall water circulation. The position of the siphon outlet pipe 5 is parallel to the position of the disturbance rotating column 7. This parallel arrangement makes the water flow path more compatible with the disturbance direction, reducing water flow resistance and improving the stability of system operation. The number of flexible filter covers 13 and... The number of water pumping pipes 11 is set accordingly, and each water pumping pipe 11 is equipped with an independent flexible filter cover 13 to ensure that the filtration effect of each water pumping channel is consistent. Second magnetic blocks 12 are fixedly connected to all four sides of the inner wall of the filter tank 1. The second magnetic blocks 12 provide a magnetic positioning structure for the installation of the inner filter cartridge 9. The side wall of the second magnetic block 12 abuts against the first magnetic block 10. The first magnetic block 10 and the second magnetic block 12 attract each other, realizing the rapid positioning and fixation of the inner filter cartridge 9 in the filter tank 1. The side of the first magnetic block 10 away from the second magnetic block 12 is fixed. An inner filter cylinder 9 is fixedly connected, providing a relatively independent growth space for seedlings. Simultaneously, it purifies the water through side-wall filtration. The disturbance plate 3 and the pumping pipe 11 are both located inside the inner filter cylinder 9, ensuring that the disturbance and pumping actions directly affect the seedling growth environment within the inner filter cylinder 9, precisely controlling the water condition. Three water level sensors 8 are fixedly connected to the inner wall of the filter tank 1. These three water level sensors 8 are arrayed on the inner wall of the filter tank 1, providing real-time feedback on water volume information. Furthermore, the different heights of the three water level sensors 8 allow for monitoring of water level changes. The system features a lower limit warning and dynamic adjustment function. The lower surface of the cover plate 2 abuts against the filter tank 1, and this abutting connection enhances the sealing between the cover plate 2 and the filter tank 1, preventing water leakage and ensuring stable internal pressure. The lower surface of the auxiliary water pump 6 is fixedly connected to the cover plate 2, and the cover plate 2 provides a stable support for the auxiliary water pump 6, ensuring its structural stability during operation. The upper surface of the cover plate 2 is fixedly connected to a controller 14, which receives signals from the water level sensor 8 and controls the operation of components such as the motor 4 and the auxiliary water pump 6, thereby realizing intelligent control of the entire water exchange system.

[0019] Working principle: First, the inner filter cartridge 9 is attracted to the second magnetic block 12 on the inner wall of the filter tank 1 via the first magnetic block 10, completing the rapid positioning and fixation of the inner filter cartridge 9 in the filter tank 1, ensuring that the inner filter cartridge 9 is installed firmly. Check whether the flexible filter cover 13 on the lower surface of the water pumping pipe 11 is installed in place, ensuring that each water pumping pipe 11 is equipped with a corresponding flexible filter cover 13 and that the connection is tight and not loose, to prevent seedlings or impurities from entering the pipe during water pumping. Confirm that the lower surface of the cover plate 2 is in close contact with the filter tank 1 to enhance the sealing between the two. Then check the cover. Check the installation status of the motor 4, siphon outlet pipe 5, auxiliary water pump 6, and controller 14 on the upper surface of plate 2, ensuring that all components are firmly fixed. Inject the water required for seedling cultivation into filter tank 1 and observe the three water level sensors 8 on the inner wall of filter tank 1. When the water level reaches the preset normal height, the water level sensor 8 transmits a signal to the controller 14, which starts the motor 4. The output of the motor 4 drives the agitator rotating column 7 to rotate, which drives the agitator plate 3 on the outer surface to rotate synchronously, stirring the water in the inner cylinder 9 and preventing seedling adsorption and sedimentation. The controller 14 synchronously starts the auxiliary water pump 6, which enhances the water flow in the siphon outlet pipe 5. The water in the inner filter cartridge 9, agitated by the disturbance plate 3, is drawn through the pumping pipe 11 (located above the disturbance plate 3), filtered by the flexible filter cover 13, and then enters the siphon outlet pipe 5, realizing directional pumping and water circulation. During operation, three water level sensors 8 monitor the water level at different heights in the filter tank 1 in real time. If the water level is lower than the lower limit or higher than the upper limit, the controller 14 receives the signal and issues an early warning, and can automatically adjust the motor 4 or the auxiliary water pump 6. The operating status is monitored, and the cleanliness of the flexible filter cover 13 is checked regularly. When blockage occurs, the flexible filter cover 13 on the lower surface of the water pumping pipe 11 can be removed for cleaning or replacement to ensure that the water pumping channel is unobstructed. If the inner filter cartridge 9 needs to be repaired, the adsorption between the first magnetic block 10 and the second magnetic block 12 can be disconnected, and the inner filter cartridge 9 can be taken out for maintenance. After maintenance, it can be re-fixed by magnetic attraction. When not in use, the motor 4 and the auxiliary water pump 6 can be turned off by the controller 14 to drain the water in the filter tank 1 and clean and maintain all components to prepare for the next use.
