When the device works, the hydraulic rod 25 is firstly driven, the slide block 24 above the hydraulic rod drives the filter screen 6 to move in the direction of the chute 23, and the diameter of the filter screen 6 is smaller than the size of fish school in the culture box 1, so that the fish school can be driven to the upper end of the culture box 1 by the filter screen 6, and the fish school is prevented from being injured; then, high-pressure gas is introduced into the cylinder 7 through a high-pressure air pump, and the piston 26 and the impact rod 16 are pushed to move downwards until the impact hammer 8 is in contact with the bottom plate 13 at the bottom of the cultivation box 1 to impact the bottom plate 13, so that the sludge on the bottom plate 13 is vibrated, the sludge is not attached to the bottom plate 13 any more, and the sludge can be removed more conveniently; meanwhile, the impact hammer 8 is also subjected to the reaction force of the bottom plate 13, and generates reverse impact on the impact hammer 8 and the upper filter screen 6. The filter screen 6 vibrates under the impact action, so that the sludge attached to the surface of the filter screen 6 can be vibrated down and flows into the water area below.

The sludge shaken by the impact hammer 8 is not attached to the bottom plate 13 any more, but floats in the water surface below the filter screen 6, at the moment, the motor is started, the stirring shaft 15 drives the stirring block 9 to rotate at the bottom of the culture box 1, rotational flows are formed below the stirring block 9 and outside the stirring block 9, water flows into the water storage cavity 4 through the drain hole 10 and the filter screen under the action of rotational flow centrifugal force due to different centrifugal forces of the water and the sludge, the water in the water storage cavity 4 is gradually increased until the water flows into the water collecting tank 21 from the overflow hole 20 above, and the water in the water collecting tank 21 finally flows back into the culture box 1 from the backflow hole 19 through the guide plate 22 again; the water in the culture box 1 can be recycled, the water and the sludge in the culture box 1 can be separated, the separated water flows into the culture box 1 again, and the water flowing into the culture box can also provide pressure for the sludge to flow downwards; the separated sludge moves to the lower part of the stirring block 9 along with the rotational flow under the action of centrifugal force and flows out of the sludge discharge hole 14; when the stirring shaft 15 rotates, the brush 11 connected below the stirring block 9 can also scrape off sludge on the bottom plate 13.

A circle of clamping grooves 2 are formed in the bottom of the top cover 12, the clamping grooves 2 are located at the top of the outer box 3, and sealing rings are arranged at the connecting positions of the clamping grooves 2 and the side wall of the outer box 3; top cap 12 is located and is bred case 1 top to be connected with outer box 3 through draw-in groove 2, make whole breed and present confined state in the case 1, the setting of sealing washer is avoided breeding 1 interior water and is spilled over from draw-in groove 2 when rotating.

The bottom of the culture box 1 is provided with a bottom plate 13, the bottom plate 13 is provided with a sludge discharge hole 14 at a position corresponding to the stirring block 9, and the bottom of the sludge discharge hole 14 is connected with a collection box 18 through a water pipe; the sludge discharge hole 14 is used for discharging sludge in the culture box 1 and recycling the sludge by using the collection box 18.

Two ends of the filter screen 6 are provided with inclined scrapers 5, and the scrapers 5 are provided with scraping teeth; the filter screen 6 is at the in-process that removes along spout 23, and scraper blade 5 can strike off the mud on breeding case 1 inner wall, is equipped with to scrape the tooth and is convenient for operate curved 1 inner walls of breeding case more.

Referring to fig. 4, in the embodiment of the present invention, an inclined water-stop plate 27 is disposed outside the impact rod 16, the bottom surface of the impact hammer 8 is an arc-shaped structure, and a plurality of elastic protrusions 28 are disposed on the impact hammer 8; the impact rod 16 drives the impact hammer 8 to move downwards and impact the bottom plate 13, and when the impact hammer moves in water, the impact hammer will be subjected to water resistance, so a water stop plate 27 is arranged outside the impact rod 16, water flow can flow along the direction of the water stop plate 27, the water resistance can be effectively reduced, and the impact force generated by the impact rod 16 is larger; the contact area of the elastic bulge 28 on the impact hammer 8 and the bottom plate 13 is small, the generated pressure is strong, so that the impact force is increased, and the elastic bulge 28 can also slow down the reverse acting force generated by the bottom plate 13.
