Description

The present invention relates to an improvement of a sorting device for cultured shellfish such as scallops and oysters.

Conventionally, in order to ship farmed shellfish such as scallops and oysters that have been cultivated and grown, sorting work is performed to divide the shellfish into large, medium and small. Ideally, this sorting work is performed manually to prevent damage to the cultured mussels, but mechanical sorting work is the mainstream in order to improve work efficiency and reduce labor.

There are a wide variety of sorting devices for cultured mussels that have been used in the past, but in order to efficiently sort cultivated mussels, the entrance side of a sorting table with a large number of holes with different inner diameters attached to the top and bottom. The one formed by attaching a hopper for accommodating cultured mussels above the sorting table is widely used.

The sorting table pivotally supports the driving force from the driving source via the pulley to one end of the support arm by eccentricity, and pivotally supports the other end to the frame body, and sorts by the eccentric movement due to the rotation of the pulley. There is known a sorting device that sorts shellfish by dropping them from holes of a predetermined size while moving the cultured shellfish on the sieve plate by swinging the table.

Therefore, it is possible to make the swinging motion of the sorting table 10 including the reciprocating motion in the horizontal direction and the vertical motion smooth. Further, since the cultured shellfish H that moves on the sorting table 10 also moves smoothly, the sorting efficiency can be improved without the possibility that the shellfish will be clogged in the holes.

Since the second drive source Tb and the second rocking mechanism Sb are located above the base frame 2, the seawater sprayed on the cultured shellfish H of the sorting table 10 is less likely to get wet in the sorting work, so that rust and corrosion due to salt damage are less likely to occur. It is possible to prevent problems caused by.

In the sorting operation step by the sorting devices 1a and 1b according to the present invention, the cultured shellfish H for shipping collected from the sea is placed on the hopper 31 or conveyed to the inlet hopper 35 by a belt conveyor. Next, by operating the motors 6 of the first and second drive sources Ta and Tb to rotate the transmission means U or the direct transmission shaft 20 from the drive shaft 7, the first swing mechanism Sa provided at both ends of the transmission shaft Alternatively, by rotating the sorting table eccentrically via the second swing mechanism Sb, the sorting table 10 makes a swing motion including a reciprocating motion in the horizontal direction and a vertical motion.

Since the first oscillating mechanism Sa and the second oscillating mechanism Sb are substantially the same as the oscillating motion, the first oscillating mechanism Sa will be described based on the oscillating motion of the first oscillating mechanism Sa. As shown in FIG. 9A, the oscillating motion of the sorting table 10 is such that when the eccentric shaft 23 comes to the uppermost position due to the rotation of the operating disk 22, the cultured shellfish H on the sieve plate 13 is in the last retracted position as shown by the arrow. It advances in the exit direction while being pushed up from the point Y to the position of the uppermost position W.

Then, as shown in FIG. 9B, when the axis of the operating disk 22 and the eccentric axis 23 move to the same horizontal position in parallel by the rotation of the eccentric axis 23, the sieve plate 13 and the cultured shellfish H both move forward in the horizontal direction. While descending from the uppermost position, it moves to the most advanced position X.

Further, as shown in FIG. 9C, when the eccentric shaft 23 rotates and moves from the most advanced position X to the lowest position Z, the sieve plate 13 descends and is at the same position as the uppermost position W in FIG. 9a. Retreat to lower position Z. When the sieve plate 13 is lowered, the sieve plate 13 is rapidly lowered, so that the cultured shellfish H on the sieve plate temporarily floats in the air and stays at the most advanced position X as it is.

Furthermore, as shown in FIG. 9D, when the eccentric shaft 23 further rotates and moves to the same horizontal position parallel to the axis of the operating disk 22, the eccentric shaft 23 rotates from the lowest position Z to the rearmost retracted position Y. Retreat while moving. Further, the cultured mussel H staying at the most advanced position X rises together with the sieve plate 13 at the most advanced position X at the position where the sieve plate 13 is retracted, and moves forward to the uppermost position W (FIG. 9a).

As described above, from the reciprocating motion in which the sorting table 10 is translated from the last retracted position Y to the most advanced position X by one rotation of the operating disk 22 and the eccentric shaft 23, and the vertical motion to the highest position W and the lowest position Z. By repeating the swinging motion, the cultured shellfish H moves from the last retracted position Y to the most advanced position X via the uppermost position W, and only the sieve plate 13 moves to the last retracted position Y again. As the sorting table 10 is tilted, the cultured shell H moves forward while making a stepping motion, and the cultured shell H is appropriately sorted from the holes 14 and 16 of the first and second sieve plates 13 and 15 and dropped and discharged. NS.

The large shellfish moving on the sorting table 10 does not fall from the hole 14 of the first sieve plate 13 but reaches the outlet side as it is and falls from the first guide shooter 37a. While moving on the first sieve plate 13, it is sifted through the holes 14 and falls on the second sieve plate 15, and the medium-sized cultured mussels move on the second sieve plate 15 as they are to the outlet and the second guide shooter 37b. Is stored in the storage container 40. Further small cultured mussels H are further sifted through the holes 16 of the second sieve plate 15 and are housed in the storage container 40 from the third guide shooter 37c for small mussels.

Therefore, since the sorting table 10 suspended on the first rocking mechanism Sa can swing the entire body evenly, the cultured shellfish H does not bounce or dance due to swinging and is moved in a horizontal state. Can be done. Further, since the cultured shellfish H can be smoothly moved without being fitted into the holes 14 and 16 of the sieve plates 13 and 15 by the rocking motion, the sorting work can be performed efficiently.

Even if the shellfish fits in the hole, the eccentric movement and the movement of moving from (b) to (c) in FIG. 9 and descending while retreating in the horizontal direction can cause the cultured shellfish to separate from the hole. It is possible to reduce the phenomenon that the state remains fitted in the hole. Therefore, it is possible to prevent shellfish from being clogged in the sorting hole and passing small shellfish without being sorted, and the cultured shellfish moving on the sieve plate can be smoothly moved without being clogged due to overlapping, and the sorting work can be performed. It can be done efficiently.

Furthermore, since the sorting table 10 reciprocates and moves up and down in the horizontal direction, when the cultured shellfish H moves while swinging on the sorting table 10, the cultured shellfish does not bounce or dance and moves in a horizontal state. Therefore, it is possible to prevent the moving cultivated mussel and the cultivated mussel from colliding with each other and cracking or cracking to be damaged.
