This creation is an automatic ejection device for fishery aquaculture bait. The device is fixed on the side of a fishery aquaculture pond and includes a positioning bracket, a bucket, a receiving tray located below the bucket to receive bait, a drive unit, and a receiving unit. An elastic picking piece rotating on the top surface of the receiving plate driven by the driving unit, wherein the receiving plate is provided with a stopper on a rotation path corresponding to the outer end of the elastic picking piece. The end will be bent by the stopper of the stopper and continue to accumulate the elastic force until the elastic dial releases the elastic force and can automatically eject the bait to a long distance to achieve the function of uniform bait. It has a simple structure and maintenance The advantages of being easy, saving power consumption and reducing maintenance cost, and improving the lack of conventional automatic bait feeders can only provide fixed-point bait.本創作為一種漁業養殖餌料自動彈射裝置，該裝置固定在漁業養殖池邊，包含一定位支架、一料桶、一位於該料桶下方以承接餌料的承接盤、一驅動單元、以及一接受該驅動單元的驅動而在該承接盤頂面旋轉的彈性撥料片，其中，該承接盤對應於彈性撥料片外側端的旋轉路徑上設有一止擋件，當彈性撥料片轉動時，其外側端會受止擋件的止擋而彎曲並持續蓄積彈力，直到該彈性撥料片釋放彈力而能夠將餌料自動彈射投灑至較遠的距離，達到均勻投餌的功能，具有結構簡單、維修容易、節省耗電及降低養護成本的優點，改善習知自動投餌器只能定點投餌的缺失。
