The utility model facilitates pulling the fish barrel and fry out of the barrel body, avoids using a net to salvage the fry inside the barrel body, avoids damage to the fry after the fry contact with the net, and avoids affecting the survival rate of the fry.

[0004] Although the above-mentioned incubator can salvage the hatched fry, some fry will always be located under the fish barrel and will not enter the fish barrel. At the same time, although fish food can be sprinkled into the fish barrel to attract the fry to enter the fish barrel, there is a lot of uncertainty. Sometimes some fry will not enter the fish barrel. Subsequently, the staff still needs to use salvage tools to salvage the fry in the barrel, which increases the labor burden of the staff. Utility Model Content

[0005] The utility model discloses a fry hatching device, which solves the problem that some fry are always located under a fish barrel and do not enter the fish barrel, and workers still need to use salvage tools to salvage the fry in the barrel, which increases the labor burden of the workers.

[0006] In order to solve the above technical problems, the utility model specifically adopts the following technical solutions:

[0007] A fry hatching device comprises a barrel body, the bottom of which is fixed with supporting legs, the bottom of which is connected with a round shell, a liftable loading shell is arranged at the bottom of the barrel body, the outer wall of the loading shell is fitted with the inner wall of the barrel body, the bottom of the loading shell is connected with a threaded pipe, and a collecting shell threadedly connected with the threaded pipe is arranged in the round shell; a motor is arranged above the barrel body, a winding rod is fixed on the rotating shaft of the motor, and a connecting rope detachably connected with the loading shell is fixed on the winding rod.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] After injecting a proper amount of water into the barrel body, the fish eggs are placed in the barrel body for hatching, and the fish eggs are located in the loading shell or the collecting shell. When the fish eggs are hatched into fry and the fry need to be salvaged, the motor is started to rotate the winding rod to wind up the connecting rope, and the connecting rope drives the loading shell and the collecting shell to move upward. In the process of the loading shell driving the collecting shell to rise, the fry are always located in the loading shell or the collecting shell. When the collecting shell moves outside the barrel body, the collecting shell is rotated to separate the collecting shell from the threaded tube, and the fry in the loading shell enters the collecting shell through the threaded tube, completing the salvaging of the fry, and the collecting shell can be transferred later. The utility model can effectively salvage the fry quickly, and there will be no fry remaining in the barrel body, thereby reducing the burden on the staff. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0013] The specific contents of the utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 and Figure 2As shown, the utility model provides a fry hatching device, including a barrel body 1, a support leg 7 is fixed to the bottom of the barrel body 1, a round shell 2 is connected to the bottom of the barrel body 1, a liftable loading shell 3 is provided at the bottom of the barrel body 1, the outer wall of the loading shell 3 is fitted with the inner wall of the barrel body 1, a threaded tube 31 is connected to the bottom of the loading shell 3, and a collecting shell 4 threadedly connected to the threaded tube 31 is provided in the round shell 2; a motor 5 is provided above the barrel body 1, a winding rod 51 is fixed to the rotating shaft of the motor 5, and a connecting rope 52 detachably connected to the loading shell 3 is fixed to the winding rod 51.

[0015] like Figure 1 As shown, both sides of the barrel body 1 are fixed with fixed blocks 6, and a fixed frame 61 connected to the two fixed blocks 6 is provided above the barrel body 1. The main body of the motor 5 is fixed on the top of the fixed frame 61, and a connecting plate 62 rotatably connected to the winding rod 51 is also fixed on the fixed frame 61; the bottom end of the connecting rope 52 passes through the top of the fixed frame 61. The motor 5 adopts a servo motor, and the connecting plate 62 can increase the stability of the winding rod 51. After starting the motor 5, the rotating shaft of the motor 5 drives the winding rod 51 to rotate, and the connecting rope 52 can be wound up, driving the loading shell 3 and the collecting shell 4 to move upward; after the loading shell 3 moves upward, the fry in the barrel body 1 will move upward with the loading shell 3. After the loading shell 3 and the collecting shell 4 move to the outside of the barrel body 1, the collecting shell 4 is separated from the threaded tube 31, and the fry in the loading shell 3 will be discharged into the collecting shell 4 through the threaded tube 31 along with the water, and the subsequent staff can transfer the collecting shell 4.

[0016] like Figure 1 As shown, a fixing beam 33 is fixed on the top of the loading shell 3, and a rectangular opening is opened on the fixing beam 33. The fixing frame 61 is U-shaped, and a rectangular block 63 matching the opening is fixed on the top of the inner side of the fixing frame 61. When the loading shell 3 is moved outside the barrel body 1, the rectangular block 63 is inserted into the rectangular opening on the fixing beam 33, so as to limit the loading shell 3 and prevent the loading shell 3 from rotating when the staff rotates the collecting shell 4.

[0017] like Figure 1 As shown, handles 41 are fixed on both sides of the collection shell 4. The arrangement of the handles 41 facilitates the staff to rotate the collection shell 4, connect or separate the collection shell 4 from the threaded tube 31, and facilitates the staff to carry the collection shell 4.

[0018] like Figure 1 and Figure 2 As shown, two symmetrical hanging rings 34 are fixed on the top of the loading shell 3, and two connecting ropes 52 are provided on the winding rod 51, and the bottom ends of the two connecting ropes 52 are respectively tied to the two hanging rings 34. When there are a lot of dirt and other impurities in the loading shell 3, the connecting rope 52 can be separated from the hanging ring 34 to clean the inside of the loading shell 3.

[0019] like Figure 1 and Figure 2 As shown, the loading shell 3 is provided with a perforation, and a fixing ring 32 is fixed at the bottom of the loading shell 3. The inner diameter of the fixing ring 32 decreases from top to bottom, and the threaded tube 31 is located at the axis of the fixing ring 32. After the loading shell 3 is provided with a perforation, when the loading shell 3 moves upward to the water surface in the barrel body 1, the water in the loading shell 3 can be discharged into the barrel body 1 through the perforation, and will not move upward with the loading shell 3. Only the collecting shell 4 has water, which is also convenient for the fry to enter the collecting shell 4 through the threaded tube 31, thereby reducing the weight of the loading shell 3; the setting of the fixing ring 32 also facilitates the fry in the loading shell 3 to enter the collecting shell 4 through the threaded tube 31.

[0020] like Figure 1 As shown, one side of the barrel body 1 is connected with a drain pipe 8. A valve is installed on the drain pipe 8, so that the water in the barrel body 1 can be discharged through the drain pipe 8 after the staff opens the valve.

[0021] When in use, first inject a proper amount of water into the barrel body 1, and then the staff put the fish eggs in the barrel body 1 for incubation. After the fish eggs are hatched into fry, when the fry need to be salvaged, the motor 5 is started to rotate the winding rod 51, and the connecting rope 52 is wound, so that the loading shell 3 moves upward. After the loading shell 3 moves upward, the fry can be driven to move upward all the time; when the loading shell 3 moves above the water surface in the barrel body 1, the fry all enter the loading shell 3, and the fry in the loading shell 3 can be discharged into the collecting shell 4 through the threaded tube 31; the subsequent staff separates the collecting shell 4 from the threaded tube 31 and transfers the collecting shell 4; and in the process of the loading shell 3 rising, the loading shell 3 can also clean the inner wall of the barrel body 1 to ensure that the inside of the barrel body 1 is clean and tidy.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
