Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] As Figures 1-4 ​As shown in the drawings, a fish spawning and egg collecting device comprises a supporting bottom plate 12, a spawning assembly for fish spawning and an isolated breeding assembly for isolating fish to collect eggs; the spawning assembly comprises a left containing frame 1, a right containing frame 11 and a partition plate 14; the left containing frame 1 is slidably arranged at the upper end of the supporting bottom plate 12, the right containing frame 11 is fixed to the supporting bottom plate 12, the side end opening of the right containing frame 11 is provided with a slot adapted to the insertion of the two side ends of the left containing frame 1, the left containing frame 1, the right containing frame 11 and the supporting bottom plate 12 enclose a cavity for breeding fish, and the partition plate 14 is detachably arranged on the inner side wall of the cavity; the spawning assembly comprises an egg collecting plate 13 and a transmission rod, and correspondingly, the lower end of the left containing frame 1 is provided with a notch adapted to the up-down sliding of the egg collecting plate 13, and the transmission rod is fixedly arranged at the lower side end of the left containing frame 1. The fish spawning and egg collecting device further comprises a linkage driving device for driving the egg collecting plate 13 to move in the vertical direction, and the transmission rod and the linkage driving device are in transmission connection.

[0024] As shown in the drawings, Figure 2 and Figure 4 As shown in the drawings, the linkage driving device comprises a transmission rod, a linear driving motor, a driving wheel 26, a first transmission wheel 25, a rotating fixed seat 24, a second transmission wheel 20, a transmission belt 19, a third transmission wheel 18, a transmission plate 17, a rotating rod 28 and a resting plate 280; the transmission rod comprises a sliding part 141 and a transmission part 140, the sliding part 141 is arranged on the side close to the driving wheel 26, the driving wheel 26 and the transmission part 140 are in meshing transmission connection, and correspondingly, the end of the transmission part 140 away from the left containing frame 1 is provided with a transmission tooth; the rotating fixed seat 24 is fixed on the side end of the supporting bottom plate 12, the first transmission wheel 25 is in rotating connection with the rotating fixed seat 24, and the first transmission wheel 25 and the driving wheel 26 are in meshing transmission connection; the rotating rod 28 is fixed with the rotating fixed seat 24, and the second transmission wheel 20 and the first transmission wheel 25 are coaxially and rotatably connected on the rotating rod 28; the second transmission wheel 20 and the third transmission wheel 18 are in transmission connection through the transmission belt 19; the transmission plate 17 is fixedly arranged at the lower end of the resting plate 280, the side end of the resting plate 280 is provided with a first meshing tooth, and correspondingly, the third transmission wheel 18 is provided with a second meshing tooth in meshing transmission with the first meshing tooth, and the third transmission wheel 18 and the transmission plate 17 are in meshing transmission connection; the egg collecting plate 13 is placed on the upper end of the resting plate 280, and correspondingly, the resting plate 280 is correspondingly arranged at the lower end of the notch.

[0025] In this embodiment, fish can be raised in the left container 1. To promote spawning, the breeder can lay fine sand on top of the egg collection plate 13 to simulate the natural environment in which fish spawn. After spawning, once the power is turned on, the linear drive motor drives the left container 1 towards the right container 11 at the fish-driving plate 10. During this movement, the left container 1 will drive the fish inside towards the right container 11 until the side of the left container 1 is fully inserted into the slot on the right container 11. At this point, the breeder can insert the separator 14 to isolate the fish within the right container.

[0026] As the left receiving frame 1 moves toward the right receiving frame 11, when the transmission part 140 contacts the drive wheel, meshing transmission occurs, causing the drive wheel 26 to rotate (to... Figure 4 (For example)

[0027] When the transmission unit 140 moves to the left, the counterclockwise rotation of the drive wheel 26 causes the first transmission wheel 25, which meshes with it, to rotate clockwise. The end of the rotating rod 28 is rotatably connected to the rotating fixed seat 24. Since both the first transmission wheel 25 and the second transmission wheel 20 are coaxially fixed on the rotating rod 28, the clockwise rotation of the second transmission wheel 20 causes the synchronously driven third transmission wheel 18 to also rotate clockwise, thereby driving the transmission plate 17 downwards. This, in turn, causes the shelf 280 fixed to the transmission plate 17 to move downwards, thus causing the egg collection plate 13 to move downwards. In practical use, the length of the transmission unit 140 and the height to which the egg collection plate 13 descends are the same. After the egg collection plate 13 descends, the aquaculture personnel can pull it out laterally and remove debris and fine sand through lateral vibration to obtain the fish eggs.

[0028] When the device is in use, during the process of sliding from the left container to the right container, the transmission part 140 will engage with the drive wheel 26 only after the fish deflector plate 10 has slid through the gap. The advantage of this setting is that it prevents the egg collection plate 13 from starting to move downwards before the fish have been driven into the right container, thus preventing some fish from escaping through the gap (where the egg collection plate is installed).

[0029] When egg collection is required again, the egg collection plate 13 is placed on top of the shelf 280, and the egg collection plate 13 can be reset by reversing the linear drive motor. At the same time, the aquaculture personnel can open the partition plate 14 again, allowing the fish to swim to the left receiving frame 1.

[0030] This embodiment also includes a support rod 121, and the linkage drive device also includes a sliding transmission rod 15. The sliding transmission rod 15 is fixed to the lower end of the shelf 280, and the sliding transmission rod 15 and the support rod 121 are slidably connected. The sliding transmission rod 15 helps to make the egg collection plate 13 more stable during the descent process.

[0031] In the embodiment, the sliding transmission rod 15 is provided with a sliding groove at the side end, and the supporting fixed rod 121 is provided with a sliding convex part 122 matched with the sliding groove.

[0032] In order to facilitate the transmission rod to pass through, the rotating fixed seat 24 is provided with a groove matched with the sliding path of the transmission rod.

[0033] The embodiment further comprises a supporting fixed frame, which comprises a fixed rod 22 and a connecting rod 30 fixedly connected with each other, the fixed rod 22 is provided with a sliding convex rib, and the side end of the transmission plate 17 is provided with a sliding groove 170 matched with the sliding convex rib.

[0034] In the embodiment, the supporting fixed frame further comprises a supporting plate 27, a resting rod 29, a supporting connecting rod 230 and a supporting foot rod 23 fixedly arranged at the lower end of the right containing frame 11, one end of the resting rod 29 is fixedly connected with the fixed rod 22, and the other end is fixedly connected with the supporting plate 27, the resting rod 29, the supporting plate 27 and the connecting rod 30 are connected to form a planar support frame for fixing the resting collecting plate 13.

[0035] In the embodiment, the collecting plate 13 is provided with a fixed block at the side end, and the upper end of the fixed block is provided with a handle 130 for facilitating the user to hold. When the collecting plate moves to below the gap, the aquaculture personnel can hold the handle and shake the collecting plate left and right to remove sundries and fine sand, so as to collect the fish eggs.

[0036] In the embodiment, the supporting bottom plate 12 is provided with a sliding block 120, and the left containing frame 1 is provided with a fixed sliding groove matched with the sliding block 120 at the side opposite to the right containing frame 11.

[0037] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
