In the first state, that is, the waste discharge state, the waste discharge sleeve net is lowered to the outside of the net box, and the waste inside the netting (2) enters the sleeve bottom (3) under the influence of seawater and is discharged through the sleeve head (4). In the second state, the waste discharge sleeve net is raised to the inside of the net box, and the waste cannot enter the waste discharge sleeve net. At the same time, raising the waste discharge sleeve net effectively prevents sea cucumbers from gathering and escaping, and prevents feed loss.

[0031] The sea cucumber farming device (100) having the said waste discharge function has a structured waste discharge net bag for discharging residual bait and excrement, and the waste discharge net bag also has an up-and-down transport function. When discharging residual bait and excrement inside the net box, the waste discharge net bag is lowered to the outer side of the bottom of the net box, and the excrement and residual bait enter the waste discharge net bag under the action of ocean currents and waves and are automatically discharged out of the box. The said device plays an important role in keeping the environment of the net box clean and reducing the occurrence of disease.

The other end of each connecting frame (103) is connected to the inner annular frame (102), and the inner side of the inner annular frame (102) is a through structure. The outer frame (101), the inner annular frame (102), and the connecting frames (103) are all pipe structures, and through holes penetrating the inside and outside are installed in the outer frame (101), the inner annular frame (102), and the connecting frames (103).

[0041] In this embodiment, as shown in FIG. 5, an annular continuous stopper belt (10) and a plurality of annular discontinuous stopper belts (11) are installed coaxially on the inner side of the bottom of the netting (2). The bottom net outside the annular continuous stopper belt (10) is a bait casting zone, and the bait is selected as a piece, granule, etc. All annular discontinuous stopper belts (11) are installed on the outer side of the annular continuous stopper belt (10), each annular discontinuous stopper belt (11) is installed within the bait casting zone, all annular discontinuous stopper belts (11) are installed sequentially from the inner side to the outer side, multiple stopper belts are installed sequentially along the circumferential direction of the annular discontinuous stopper belt (11), the stopper belts of any two adjacent annular discontinuous stopper belts (11) are all installed staggered, the axis of the annular continuous stopper belt (10) and the axis of the penetration structure coincide, and the annular continuous The diameter of the stopping belt (10) is larger than the diameter of the through structure. The bottom of a conventional net box is a flat net made of netting, and sea cucumbers inside the net box are generally distributed mostly in the corner areas of the bottom of the net box (referred to as the "corner effect"). When thrown bait sinks to the bottom of the net box, under the action of ocean currents and waves, the bait gathers in the central area of ​​the bottom of the net box, making it difficult for the sea cucumbers to eat, leading to spoilage and waste of the bait. By installing an annular continuous stopping belt (10) and an annular discontinuous stopping belt (11), the sea cucumber bait is effectively prevented from flowing to the center of the bottom of the net box, allowing the sea cucumbers to eat conveniently and extending the feeding time.

[0045] Further, the netting (2), sleeve bottom (3), and sleeve head (4) are all made of nylon mesh, the bottom net located on the outer side of the annular continuous jersey belt (10) is made of nylon mesh with a hole diameter of 0.2 cm, the bottom net located on the inner side of the annular continuous jersey belt (10), sleeve bottom (3), and perimeter are all made of nylon mesh with a hole diameter of 0.7 cm, and the sleeve head (4) is made of nylon mesh with a hole diameter of 1.0 to 1.5 cm. It should be explained that the purpose of the holes in the netting (2) and the holes in the sleeve bottom (3) is both for water exchange, and dirt is mainly discharged through the mesh holes in the sleeve head (4).

[0046] Further, the netting (2) is a rectangular structure.

[0047] In this embodiment, as shown in FIGS. 1 and 2, the net box comprises a net frame (12), a floating mechanism (13), a netting (2), a support mechanism (1), and several second weights (14). The floating mechanism (13) is installed below the net frame (12) and is fixedly connected to the net frame (12), so that the net frame (12) floats on the sea surface. The upper part of the netting (2) and the net frame (12) are connected to each other and are open below the sea surface. The second weights (14) are all connected to the outer side of the bottom of the netting (2), and the second weights (14) are all evenly installed along the circumference of the bottom of the netting (2), and the second weights (14) allow the netting (2) to naturally sink underwater.

[0048] Further, the first weight (5) and the second weight (14) are both cylindrical in shape, and both the first weight (5) and the second weight (14) are made of cement.

[0049] In this embodiment, the floating device (13) is a buoy. It should be noted that the floating device (13) is not limited to a buoy and may be any other device capable of causing the net frame (12) to float on the sea surface. Furthermore, there are multiple buoys, and all buoys are installed symmetrically on both sides of the net frame (12), and the specific number of buoys is determined according to actual demand, and the number of buoys in FIG. 1 is specifically 4.

[0050] As a step forward, the buoy was made of polystyrene.
