The first motor 44 is started to drive the gear 441 to rotate, so that the gear ring 431 and the fifth sleeve 43 are driven to rotate, the water collecting pipe 5 on the supporting rod 51 is driven to rotate, and the cylindrical netting 2 is washed.

In particular, the flushing structure comprises a number of spray heads 53 and an electric water pump 54.

The plurality of spray heads 53 are sequentially arranged on one side of the water collecting pipe 5 close to the cylindrical netting 2 from top to bottom, and the spray heads 53 are communicated with the water collecting pipe 5.

The electric water pump 54 is fixedly arranged on the outer side of the frame 1, an inlet of the electric water pump 54 is connected with an external water source, and an outlet of the electric water pump 54 is connected with the water collecting pipe 5.

Start electric water pump 54, with in external water source suction to collector pipe 5, then spout through shower nozzle 53, along with the rotation of collector pipe 5, shower nozzle spun water constantly washes the inside wall of cylindric etting 2, will adhere to the seedling on cylindric etting 2 lateral wall and wash down, improves the clearance efficiency of mussel seedling on the cylindric etting 2.

Particularly, the upper and lower both ends level of rotating tube 4 has set firmly two backup pads 61, two backup pad 61 is just right from top to bottom, two rotate through axis of rotation 63 between the backup pad 61 and be provided with guide plate 6, the axial of axis of rotation 63 is unanimous with the length direction of rotating tube 4, is located and vertically sets firmly first pin 64 and second pin 65 on the backup pad 61 of guide plate 6 below, and first pin 64 and second pin 65 are located the left and right sides of axis of rotation 63 respectively, and when rotating tube 4 clockwise turning, guide plate 6 rotates to contacting with first pin 64, and when rotating tube 4 anticlockwise rotation, guide plate 6 rotates to contacting with second pin 65.

First pin 64 and second pin 65 can inject the rotation range of guide plate 6, when rivers drive impeller 41 and rotating tube 4 and rotate, guide plate 6 between two backup pads 61 then rotates, under the effect of rivers, make less contained angle between guide plate 6 and the cylindric etting 2 unanimous with the direction of rotation all the time, the water around the guide plate 6 extrusion cylindric etting 2 of slope, make the inside wall of cylindric etting 2 of constantly assaulting of water around the cylindric etting 2, wash the mussel seedling on the cylindric etting 2, and the operation is simple.

Specifically, the guide plate 6 is provided with a plurality of guide holes 62.

The setting up of water conservancy diversion hole 62 can reduce guide plate 6 pivoted water flow resistance, increases guide plate 6's slew velocity, and increase water improves the efficiency of cleaing away of mussel seedling on cylindric etting 2 to the impact force of cylindric etting 2.
