The invention discloses a snail release device and aims to provide a snail release device which not only is convenient to carry out a release operation, but also can effectively solve a problem that currently, when snails are manually released, snail fries need to be packed, resulting in that shells of the snail fries are damaged to influence a release survival rate of the snail fries. The snail release device comprises a water pump, a main pipeline, a fry culture box of which the upper end is open, a plurality of floating attachment plates sequentially distributed in the fry culture box fromleft to right, a plurality of guide structures corresponding to the floating attachment plates one to one, and a plurality of self-driven flushing devices corresponding to the floating attachment plates one to one; a vertical release pipe is arranged on the bottom wall of the fry culture box; and a piston which can be taken out is arranged in the vertical release pipe. Each guide structure comprises vertical guide slots arranged on both front and rear inner side walls of the fry culture box, and the floating attachment plates are inserted in the vertical guide slots of the corresponding guidestructures; and each self-driven flushing device comprises a valve element sleeve and an upper valve sleeve, a middle valve sleeve and a lower valve sleeve which are sequentially communicated.
本发明公开了一种螺类放流装置,旨在提供一种不仅放流操作方便,而且可以有效解决目前的人工螺类放流时,需要打包螺类苗种,导致螺类苗种的外壳破损,而影响螺类苗种的放流成活率的螺类放流装置。它包括水泵、总管道、上端开口的苗种养殖箱、若干由左往右依次分布在苗种养殖箱内的浮动附着板、若干与浮动附着板一一对应的导向结构、若干与浮动附着板一一对应的自驱动冲水装置,苗种养殖箱的底壁设有竖向放流管,竖向放流管内设有可取出的活塞。导向结构包括设置在苗种养殖箱的前后两内侧壁上的竖直导槽,浮动附着板插设在对应的导向结构的竖直导槽内;自驱动冲水装置包括阀芯套及依次连通的上阀套、中阀套与下阀套。
