When the floating attachment plate moves upwards from the vertical guide groove and abuts against the box cover, the lower end of the valve core sleeve is positioned in the middle valve sleeve. The case lid can be used for covering the upper end opening of seedling culture case on the one hand, and on the other hand can also be used for spacing the attachment plate that floats, avoids the snail device of releasing to flow the in-process (being water pump work promptly), and the attachment plate that floats is shifted out by the last port of vertical guide slot.
Further, as shown in fig. 1 and 2, when the floating attachment plate is supported on the lower end of the vertical guide groove of the corresponding guide structure, the water inlet of the valve core sleeve connected with the floating attachment plate is located in the corresponding lower valve sleeve.
Further, as shown in fig. 2, a limiting block 16 is arranged on the inner wall of the vertical discharge pipe, and the piston is located above the limiting block. Therefore, the piston can be limited by the limiting block and can be moved out through the upper end of the vertical discharge pipe.
Further, as shown in fig. 1 and 2, the seedling culture device further comprises a vertical operating rod 14, the lower end of the vertical operating rod is connected with the piston, and the upper end of the vertical operating rod is located above the seedling culture box. So, the operator can make the piston shift out or be pushed in by the upper end of vertical discharge tube through vertical action bars with the piston up-shifting or down-shifting, makes things convenient for among the actual operation.
Further, as shown in fig. 1, the bottom wall of the seedling culture box is a downward-recessed conical bottom wall, and the upper end of the vertical drainage pipe is connected with the bottom end of the conical bottom wall. Therefore, the snail seeds falling on the bottom wall of the seed culture box can flow out of the vertical releasing pipe into the releasing sea area along with the water flow.
Further, as shown in fig. 1, the outlet of the water pump is provided with a three-way joint. One end of the three-way joint is connected with an outlet of the water pump, one end of the main pipeline is connected with the second end of the three-way joint, and the third end of the three-way joint is communicated with the inner cavity of the seedling culture box through a water supply pipeline 13. So, in the water pump working process, can also supply water in the case is bred to the seed through water supply pipeline, make the seed breed and have sufficient sea water in the case to make spiral shell class seed can flow out in the vertical release pipe along with the rivers and flow in the release sea area together.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, alterations and equivalents of the above embodiments according to the technical spirit of the present invention are still within the protection scope of the technical solution of the present invention.
