[0004] Due to the small size of the farmed seedlings, in order to prevent the farmed seedlings from being discharged along with the sewage, the size of the sewage holes set on the farmed riverbed is generally small. In this way, the leftover bait and excrement produced during the breeding process may be blocked in the sewage holes. This blockage will hinder the normal discharge of sewage, thereby affecting the water quality of the breeding environment. Secondly, the leftover bait and excrement may have some viscosity. These pollutants will adhere to the farmed riverbed, which is not only difficult to clean, but will also gradually decompose over time, releasing harmful substances and causing water quality deterioration. The deteriorated water quality may contain higher levels of harmful substances such as ammonia nitrogen and nitrite, which are extremely detrimental to the healthy growth of the farmed seedlings, and may cause the farmed seedlings to grow slowly, have decreased immunity, and even die in large numbers.

[0026] Reference Figure 1 The moving component includes a motor 6 fixedly connected to the side wall of the breeding box 1, a reciprocating screw rod 7 is rotatably connected to the inner side of the breeding box 1, the output shaft end of the motor 6 is axially connected to one end of the reciprocating screw rod 7, a sliding rod 8 is fixedly connected to the inner side of the breeding box 1, and two connecting rods 9 are fixedly connected to the mounting frame 4, one of the connecting rods 9 is threadedly sleeved on the reciprocating screw rod 7, and the other connecting rod 9 is slidably sleeved on the sliding rod 8. Under the guiding and limiting action of the sliding rod 8, the rotation of the reciprocating screw rod 7 will not drive the mounting frame 4 and the connecting rod 9 to rotate, but drive the mounting frame 4 to move horizontally along the axial direction of the sliding rod 8, so that the two brush plates 5 also move together, thereby playing a role in brushing away dirt.

[0027] Reference Figure 1-5 The vibration assembly includes a driving member and two connecting members, the connecting member is used to connect the brush plate 5 and the mounting frame 4, and the driving member is used to drive the two brush plates 5 to vibrate.

[0028] Reference Figure 2 , Figure 3 and Figure 4 The connecting part includes a guide rod 10 fixedly connected to the inner side of the mounting frame 4, and the brush plate 5 is slidably mounted on the guide rod 10. The cross-section of the guide rod 10 is a rectangular structure, so that the brush plate 5 can maintain a horizontal state, thereby ensuring that the brush plate 5 can always be in contact with the breeding bed 2 to ensure the cleaning effect. An air bag 12 is provided between one end of the brush plate 5 and the mounting frame 4, and a spring 11 is provided between the other end of the brush plate 5 and the inner side of the mounting frame 4. Under the action of the spring 11 and the air bag 12, the brush plate 5 can vibrate as the mounting frame 4 moves, which can effectively ensure the cleaning effect of the brush plate 5 on the breeding bed 2.

[0029] Reference Figure 1 , Figure 3 and Figure 5The driving member includes a control cylinder 13 fixedly connected to the side wall of the breeding box 1, the inner sealing sliding connection of the control cylinder 13 is connected to the slide plate 14, the side wall of the slide plate 14 is fixedly connected to the sleeve 15, the end of the sleeve 15 away from the slide plate 14 extends to the outside of the control cylinder 13, the other end of the reciprocating screw rod 17 is axially connected to the reciprocating screw rod 2 16, the sleeve 15 is threadedly sleeved on the reciprocating screw rod 2 16, and the control cylinder 13 is connected with a connecting pipe 17 and a connecting pipe 2 18, and the connecting pipe 17 and the connecting pipe 18 are connected.

[0030] Reference Figure 1 The side wall of the mounting frame 4 is in contact with the inner side of the breeding box 1, which can increase the lateral distance of the brush plate 5, so that the brush plate 5 can fully contact with the breeding bed plate 2 to ensure the cleaning effect.

[0031] The specific working principle of the utility model is as follows:

[0032] When cleaning, start the motor 6, and the output shaft end of the motor 6 rotates to drive the reciprocating screw rod 7 to rotate. Under the guiding and limiting action of the slide bar 8, the rotation of the reciprocating screw rod 7 will not drive the mounting frame 4 and the connecting rod 9 to rotate, but drives the mounting frame 4 to move horizontally along the axial direction of the slide bar 8, so that the two brush plates 5 also move together. The movement of the brush plate 5 can brush off the residual bait and excrement adhering to the breeding bed plate 2. At the same time, the bristles on the brush plate 5 can squeeze the drainage holes on the breeding bed plate 2 to prevent the drainage holes from being blocked. In this way, the dirt can be discharged smoothly, effectively preventing the deterioration of the water quality and ensuring the normal growth of the cultured seedlings.

[0033] Furthermore, when the reciprocating screw rod 1 7 rotates, it also drives the reciprocating screw rod 2 16 to rotate. Since the cross-section of the sleeve 15 is a U-shaped structure, the control cylinder 13 guides the movement of the sleeve 15, so that the rotation of the reciprocating screw rod 2 16 can drive the horizontal movement of the sleeve 15, so that the slide plate 14 can move in the control cylinder 13. When the slide plate 14 moves to one side, it squeezes the air on this side, allowing the air to enter one of the airbags 12, thereby enabling the brush plate 5 connected to the airbag 12 to move. When the slide plate 14 moves in the opposite direction, the airbag The air in 12 can be sucked back into the control cylinder 13, and then under the action of the spring 11, the brush plate 5 can be reset, and at the same time, the other brush plate will move under the expansion of the other airbag 12, that is, when one brush plate 5 moves in one direction, the other brush plate 5 moves in another direction. The above steps are repeated in this way, and the two brush plates 5 can vibrate, and the vibration direction is perpendicular to the movement direction of the mounting frame 4, and the two brush plates 5 vibrate alternately, which can ensure that the bristles on the brush plate 5 can be evenly and fully in contact with the breeding bed 2, effectively ensuring the cleaning effect of the brush plate 5 on dirt.
