Laying a gauge plate with a large number of through holes of the same size on a sorting case with a rubber roller attached to the bottom, placing a shell on the upper surface of the gauge plate, and using a combination of a motor, a pulley, and an endless belt. Vibration was mechanically applied in the vertical direction, and shellfish and the like were dropped from the through holes for selection.

[0003]

However, in the above sorting machine, since the sorting case is vibrated with a large amplitude in the vertical direction together with the gauge plate, the sorting is carried out between the upper position and the lower position of the gauge plate. It means sorting by the vibration width, that is, when moving the gauge plate to the upper position, the object to be sorted is flipped up a little and then the gauge plate is moved downward.
The object to be sorted is dropped on the gauge plate, and at the next moment when it falls, the process of flipping it up again is repeated, and the object to be sorted is dropped from the through hole to sort. Therefore, there is a problem in that it is very important for the aquaculture shellfish and other items to be sorted, which is extremely important and should not be damaged.

In addition, no soundproofing measures have been considered in the conventional sorters, and the noise is high and hinders other work.
People who work over time are tired and annoy other people, and they cannot work for a long time or at night.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and was devised as a result of the study.
