DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shellfish automatic sorter used to sort shellfishes such as scallops, akoya shells, and sea cucumber by size.

[0002]

2. Description of the Related Art Shellfish such as scallops, akoya and other shellfish during cultivation need to be sorted by size for cultivation. An automatic sorting machine is used for this sorting. A main automatic sorting machine is an automatic sorting machine which was first developed by the present applicant and registered as a utility model (No. 2142924). As shown in FIGS. 7 and 8, this automatic sorting machine mounts rail-shaped receiving members 55 in two stages vertically on the inner surface of a gutter-shaped case 52 having a wide upper opening. A diaphragm 51 having a large number of selection holes 50 formed therein is inserted to form a selection body 60,
This case 52 is disposed inside the metal frame 54 at a downward inclination, and the upper bottom surface of the case 52 is
4 is connected to an upper end of a swing arm 57 attached to the swing arm 57 via a rotary bearing 61, and a lower bottom surface of the lower sorting body 60 is supported by a frame 54 via an elastic urethane support rod 62. . With this configuration, when the crank rod 63 is reciprocated in the direction of the arrow by the motor 56 in FIG. 8 to rotate the swing arm 57, the case 52 vibrates back and forth, and the
Vibrates in the same direction and the diaphragm 51 inserted into the groove of the receiving member 55 also vibrates back and forth, and furthermore, the diaphragm 51 can freely vibrate in the groove back and forth, left and right, and up and down. is there. Also, a hopper 53 is provided above the upper sorting body 60.
And the hopper 53 is connected to the case 52 by a connector 58. When the case 52, the receiving member 55, and the vibration plate 51 are vibrated as described above by the rotation of the motor 56, the hopper 53 is connected through the connector 58. The hopper 53 also vibrates. In this case, the upper diaphragm 5
The shells A that have fallen on 1 slide down while vibrating on the diaphragm 51, while the shells A having a smaller outer diameter than the sorting holes 50 of the diaphragm 51 pass through the sorting holes 50 and fall on the lower diaphragm 51. The shells A that have been dropped and sorted on the lower diaphragm 51 slide down on the diaphragm 51, while the shells A having a smaller outer diameter than the sorting holes 50 of the diaphragm 51 are sorted. It falls down from 50 and is sorted again.

[0003]

The automatic sorting machines shown in FIGS. 7 and 8 function well with this, but have the following problems to be mentioned. (1) Shellfish A easily gathers at the center in the width direction of the outlet of the hopper 53, and the shellfish A is gathered from there, and the upper sorting body 6 is collected.
In some cases, the shellfish A falls on the zero vibration plate 51 and falls without overlapping the entire surface of the vibration plate 51. For this reason, the shellfish A, which would normally fall from the selection hole 50 while sliding down on the diaphragm 51, does not fall from the selection hole 50, but slides on another shellfish A and exits from the diaphragm 51. It may slide down to the point, and the sorting accuracy decreases. (2) Since the sorting work of shellfish A is performed while watering shellfish A, light juvenile shellfish adhere to each other with water when sorting,
It adheres to the surface of the hopper 53. For this reason, if a large amount of juvenile shellfish is thrown into the hopper 53 at once,
In some cases, even if vibration is applied, the juvenile shellfish may not flow down onto the sorting body 60 smoothly. Therefore, conventionally, the juvenile shellfish has to be divided and put into the hopper 53, which lowers the working efficiency.

[0004]

The present invention has a simple structure,
It is an object of the present invention to provide a shellfish automatic sorting machine that allows a shellfish to be fed into a hopper smoothly and automatically even when a large amount of shellfish is thrown into the hopper at one time.

The first automatic shellfish sorter of the present invention vibrates a sorting body having a large number of sorting holes, and sends out the shellfish 3 to the outlet side of the sorting body 2 while reducing the size of the shellfish 3 smaller than the sorting hole 1. In the automatic sorter for shellfish in which the shells 3 are shaken off from the same sorter hole 1, a hopper 4 for charging the shellfish 3 is provided above the sorter 2, and the shellfish 3 in the hopper 4 is provided at the bottom in the hopper 4. Conveyor 5 to send out of hopper 4
