[0024] The working principle of the fry releasing device is as follows. When the device is used to release fry into a pond, first, the box 14 is connected and fixed with the transport vehicle box through the locking assembly, and the box 14 is immersed in the water in the vehicle compartment. The fry can contact the hopper 21 and be attracted by the bait in the hopper 21. According to the water area, the guide and conveying mechanism is assembled, so that the length of the multiple guide and conveying mechanisms can span the water area as much as possible. The bottom end of the guide pipe 27 is immersed in water. According to the water span, the shunt assembly is spliced, the left end of the connecting pipe 2 is inserted into the insertion slot 101 of the right end of the floating pipe 1, and the zipper mechanism 5 is closed to realize the connection of the floating pipe 1 and the connecting pipe 2. The two ends of the first hose 31 are connected through the insertion joint 32 to realize the conduction. The bottom end of the guide pipe 27 is connected with the connecting pipe 2 through the insertion slot 101 and the zipper mechanism 5. The assembled guide and conveying mechanism is sent into the fish pond, and under the action of the buoyancy, the guide and conveying mechanism floats on the water area and spans the pond. The bottom end of the input hose 36 is sent into the pond and immersed in water.

[0025] The device is started, and the conveyor belt device 15 rotates clockwise. Under the attraction of the bait, the fry will gather on the right side of the hopper 21. The conveyor belt device 15 operates to drive the net hopper 16 to rotate clockwise to catch the fry. When the net hopper 16 loaded with fry moves to the upper end of the conveyor belt device 15, the fry is discharged and slides onto the baffle 23, and then slides into the sliding plate 22 through the baffle 23, and then is sent into the guide pipe 27 through the sliding plate 22, and then slides into the connecting pipe 2 and the floating pipe 1 along the guide pipe 27. Through the terminal control device, the motor 6 is intermittently reversed. The motor 6 is started to drive the gear 7 to move the rack 8. The rack 8 drives the connecting plate 9 to move in the sliding cavity 103. The connecting plate 9 moves to drive the two insertion rods 11 to deflect the two swing rods 10. The swing rod 10 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the sealing plate 3 to deflect. The two sealing plates 3 deflect towards the same direction. The sealing plate 3 deflecting towards the floating pipe 1 blocks the floating pipe 1, and at the same time changes the flow direction of the floating pipe 1. The sealing plate 3 deflecting outwardly makes the overflow hole 102 open, and the fry flows out through the overflow hole 102.

[0026] Under the control of the terminal, the guide mechanism guides and conveys the fry, and under the cooperation of multiple linkage mechanisms, the two sealing plates 3 change the flow direction of the floating pipe 1 to discharge the fry in different areas of the water area, which avoids discharging all the fry to a local area when the fry enters the pond, prevents overcrowding and oxygen deficiency, and improves the survival rate of the fry.

[0027] During discharge, the motors 6 in multiple shunt assemblies are intermittently reversed under the terminal control to make the overflow holes 102 of the floating pipes 1 in different areas open and closed, so as to realize the interception and discharge of the fry.

[0028] When the fry is unloaded, the pump body device 35 is operated to suck water from the fishpond through the input hose 36 and discharge through the second hose 37 and the third hose 38, the water flow discharged through the second hose 37 is sprayed through the spray pipe 34 to discharge the fry in the net basket 16, facilitating the separation of the net basket 16, the water flow discharged through the third hose 38 is discharged through the horizontal pipe 29 on the upper side of the guide pipe 27, flows through the multiple first hoses 31 and the horizontal pipe 29 on the floating pipe 1, and is discharged from the shunt pipe 30 to transport the fry away from the box body 14, and the fry blocked by the sealing plate 3 is sent out through the overflow hole 102, so that the fry is discharged to different water areas.

[0029] Under the cooperation of the drainage mechanism and the guide assembly, the water in the fishpond can be discharged into the guide mechanism, the fry is contacted with the water in the fishpond in advance when being discharged to different water areas, facilitating the adaptation of the fry to the environment in the fishpond.

[0030] The guide mechanism is a splicing structure as a whole, the length of the guide mechanism is adjusted according to the span of the water area, so that different span water areas can be adapted, and the fry is conveniently discharged to different areas.

[0031] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, the scope of the present application is defined by the appended claims and their equivalents.
