[0040] In an embodiment of the present invention, the water volume control device 26 includes an annular floating plate 40, a pull rod 41, and a second blocking ball 42.

The annular floating plate 40 is made of a high buoyancy material.

[0042] In one embodiment of the present invention, water connection interfaces 17 are provided at both ends of the water supply pipeline 14. A plurality of water supply interfaces 16 are distributed along the pipeline on the water supply pipeline 14. The water supply interfaces 16 are connected to the bottom of the extension pipe 25 through hoses 13. The irrigation assembly 5 includes a water tank 6, a water pump 7, and a pipeline 8. A water storage chamber and a recovery chamber are provided in the water tank 6. One end of the water pump 7 is connected to the water storage chamber of the water tank 6, and the other end of the water pump 7 is connected to the water connection interface 17 at one end of the water supply pipeline 14 through the pipeline 8. The water connection interface 17 at the other end of the water supply pipeline 14 is connected to the recovery chamber of the water tank 6 through a water pipe.

[0043] Working principle: When using a cultivation device for agricultural seedling raising of the present invention to cultivate seedlings, relevant personnel can pre-fill the seedling raising soil into the seedling raising boxes 11 in each water storage bin 10, and then place the specified seedling seeds or seedlings into the corresponding seedling raising boxes 11 according to requirements. When the seedling raising box 11 is installed in the water storage bin 10, the water path in the extension pipe 25 is in an open state. At this time, relevant personnel can start the water pump 7 to pump water from the water tank 6 and transport it to each water supply pipeline 14 through the pipeline 8, so that the irrigation water is transported to the extension pipe 25 through each water supply interface 16 in the water supply pipeline 14 through the hose 13, and the water is transported from the open extension pipe 25 into the water storage bin 10. As the water flows in, the water level in the water storage bin 10 rises. At this time, the annular floating plate 40 rises in the water storage bin 10 along the guide rod 28 under the buoyancy of the water. When the annular floating plate 40 rises until the second plugging ball 42 suspended by the pull rod 41 at its bottom reaches the second sealing ring 33, the water flow into the water storage bin 10 gradually decreases until the second plugging ball 42 cooperates with the second sealing ring 33 to close the water path in the extension pipe 25. At this time, the water level in the water storage bin 10 reaches the maximum limit of irrigation, realizing the automatic control of the water level therein to avoid excessive irrigation caused by too high a water level, enabling the water level in each water storage bin 10 in the use state to be automatically adjusted and controlled. At this time, the water-absorbing cotton wicks 18 penetrated in the seedling raising boxes 11 can absorb water for irrigation.

[0044] When it is necessary to disassemble a specified seedling raising box 11, the water path of the disassembled seedling raising unit 12 can also be automatically closed to avoid irrigation waste.

[0045] Specifically, the relevant personnel manually take out the seedling-raising box 11 magnetically adsorbed on the water storage bin 10. At this time, without the downward pressure of the seedling-raising box 11, the annular pressing plate 27 rebounds under the cooperation of the spring 32 and the support member 31, so as to drive the installation outer ring 29 to slide upward along the outer wall of the extension pipe 25 through the guide rod 28. At this time, while the magnetic adsorption inner ring 30 moves upward with the installation outer ring 29, due to the magnetic adsorption principle with the magnetic adsorption outer ring 37, the annular installation seat 36 lifts the first plugging ball 39 through the push rod 38 until the first plugging ball 39 abuts against the opening of the first sealing ring 34 to block it. At this time, the installation outer ring 29 also reaches the highest limit position to maintain the plugging effect here, thereby realizing the closing of the water circuit of the extension pipe 25 of the seedling-raising unit 12 in the state where the seedling-raising box 11 is not installed, so as to realize the automatic water circuit regulation of each seedling-raising unit 12 on the premise of unified water supply and irrigation.

[0046] It should be noted that the magnetic attraction force generated by the magnetic attraction protrusion 20 installed at the edge 19 of the seedling-raising box 11 and the magnetic attraction card slot 22 arranged in the installation groove 21 is greater than the supporting force provided by the spring 32 in cooperation with the support member 31 for the annular pressing plate 27, so that the seedling-raising box 11 can be stably installed in the corresponding water storage bin 10. And a limiting block 43 is also arranged on the guide rod 28 to limit the upward lifting process of the installation outer ring 29 to ensure that the magnetic adsorption inner ring 30 and the magnetic adsorption outer ring 37 can achieve close magnetic traction cooperation throughout the process.

[0047] It should be noted that the length of the pipeline 8 in the irrigation assembly 5 is adjustable and can be adjusted according to requirements. Therefore, when the relevant personnel need to rotate and unfold the specified support floor 2 on the seedling-raising rack 1 to operate the seedling-raising device 4, it will not affect the operation due to the layout of the pipeline 8. And the layout of the pipeline 8 can be adjusted according to requirements without any constraints, which is well-known and easily modified by those skilled in the art. And whether the water supply circulates or not can also be adjusted by itself.

[0048] It should be further noted that in order to ensure the stability of the seedling-raising rack 1, a breeding base can be set at the bottom of the seedling-raising rack 1.

[0049] In summary, for the cultivation device for agricultural seedling raising of the present invention, each seedling raising unit exists independently. It can control the opening and closing of the water path according to the cooperation of the water path closing device and the plugging device therein, and according to whether the seedling raising box in each seedling raising unit is placed. The automatic control of irrigation for each seedling raising unit is realized. Moreover, the water volume control device arranged in the water storage bin can control the opening and closing of the water path according to the fluctuation of the water level, effectively avoiding the influence of too high water level in the water storage bin on the irrigation effect, realizing the automatic adjustment of the water level, avoiding the waste of water resources in the traditional sprinkler irrigation method. The water guiding cotton core inserted into the seedling raising box realizes capillary water supply, ensuring that each seedling absorbs water as needed and reducing the operation of frequent manual water replenishment. The seedling raising box and the corresponding water storage bin are installed in a magnetic adsorption manner, which is convenient for disassembly and maintenance. And by using the installation or non-installation of the seedling raising box as a trigger point, the water path closing device controls the plugging device in the extension pipe through the magnetic adsorption of the magnetic inner ring and the magnetic outer ring to control the opening and closing of the main water path, realizing the automatic control of the opening and closing of the irrigation water path for each seedling raising unit, with flexible use and effectively avoiding the waste of water resources. The annular floating plate with high buoyancy performance monitors the water level in the water storage bin, and controls the closing and opening of the extension pipe by controlling the lifting of the second plugging ball, so as to realize the regulation of the water level in the water storage bin, control the irrigation water volume for each seedling raising unit, and make the seedlings in each seedling raising box absorb water as needed, avoiding over-irrigation or excessive irrigation. The water supply pipeline adopts a series-connected annular design, and cooperates with the recovery cavity of the water tank to realize the recycling of water resources, avoiding the waste of traditional one-way irrigation. The support bottom plate is rotatably connected to the support column through the connecting part, realizing the flexible adjustment of the seedling raising rack. The rotation angle of the seedling raising tray can be adjusted according to the light requirement, or rotated to a position convenient for operation for maintenance, improving the space utilization rate and operation convenience.
