Drying the shelf: and starting the motor 3, driving the rotary main shaft 2 to rotate by the motor 3 through a belt, further driving the placing platform 4 and the shelf limiting frame 5 to simultaneously rotate, spin-drying the shelf, discharging water on the shelf from the through hole 6, stopping the motor 3 after the shelf spin-drying operation is completed, returning the second oil cylinder 19 to the initial position, enabling the shelf limiting frame 5 to ascend to the initial position, and taking out the spin-dried shelf from the top surface of the placing platform 4.

The shelf can be dried quickly, the drying speed of the washed shelf is increased, the washed and dried shelf can be used for breeding silkworms in the next stage at once, the utilization rate of the shelf is improved, and the number of the shelves is reduced appropriately.

The utility model discloses repeated step d to step f can carry out the operation of spin-drying to different batchs of shelf, improves the efficiency of spin-drying of shelf.

The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions or modifications made based on the present invention to solve the same technical problems and achieve the same technical effects are all covered by the scope of the present invention.
