出端部より搬出される。 Then, when the hinge part of the cultured shellfish is placed first and both side edges of the cultured shellfish are fed, only the both side edges of the cultured shellfish are held by the belt conveyor,
The shells are transported one after another while maintaining or retaining this clamped state and the posture of the shellfish, and as each shellfish passes through the rotary grinding body in turn, each claw of each rotary grinding body hits the surface of the shellfish and scrapes off the deposits. During this time, each shellfish moves forward while being held between its both side edges, and the cultured shellfish from which the deposits have been scraped off is carried out from the carrying-out end of the conveyor.

The distance between a, 21b, and 22b is determined according to the size of the cultured shellfish A to be transported (for example, two-year shellfish, three-year shellfish), and then the width of the group of claws 43 of each rotary grinding body 40 is set to this value. In addition, for example, the number of spring members 44 can be increased or decreased in FIGS. 3 and 4, or the number of pawl support seats 60 can be changed in FIGS. 8, 9, and the number of discs 70 can be changed in FIGS. Increase or decrease the number of grinding bodies 40
are formed and fixed to the drive shaft 41 respectively, and the claws 4
At the point where the virtual cylindrical circumferential surface S formed at the tip position of No. 3 almost reaches the vicinity of the clamping surface of the conveyor 20,
The vertical position of the bearing 42 of the drive shaft 41 is adjusted, and the conveyor 20 and the upper and lower rotary grinding bodies 40 are rotated in the counter directions shown by the arrows. When the radius of the virtual cylindrical surface of is approximately 25 cm, the rotation speed is set to 300 to 600 rpm, and the cultured shellfish A are sequentially fed with their hinges facing forward, a pair of left and right upper and lower V belts 21a, 22a and 21b ,
22b, both sides of the cultured shellfish A are held between the upper and lower sides, and the cultured shellfish A is conveyed toward the rotary grinding body 40.
The individual claws 43 hit the surface, and each claw 43 moving in the rotational direction sequentially collides with the hinge part of the surface of the cultured shellfish A, as shown in FIG. 12, a, b, and c, and continues to scratch the surface. , scrape off the Fuji pot, seaweed, parasites, etc. that are attached to it.

を行える。C. Effects of the Invention The first method invention involves holding only both sides of a cultured shellfish, transporting the shellfish with the hinge part at the top while maintaining that position, and removing harmful deposits on the surface of the shellfish with the plurality of claws. The method allows cleaning of cultured shellfish by removing the shellfish by removing it, avoiding contact of a large number of claws with the fragile parts on both sides of the shellfish, sufficiently protecting the shellfish, eliminating the conventional hand-holding work.

がないから安全である。 In the second device invention, the first method invention can be carried out, and a conveyor 20 is provided which can grip only both sides of the shellfish A and convey it to the rotary grinding body 40. It is possible to securely hold the shellfish A, especially by pinching the fragile parts on both sides of the shellfish, to avoid contact with the rotating grinding body 40, to protect the shellfish A, and to avoid damaging the shellfish A, and to hold the shellfish A in the conventional manner. It is safe because there is no

順次到来するごとに同様の効果を奏する。 In the third device invention, each claw 43 moves toward the center in the radial direction while escaping in the circumferential direction due to the contact resistance with the shellfish A, so that each claw 43 moves along the surface of the shellfish A. Each claw 43 moves while being in contact with each other, which has the effect of scraping off deposits without damaging the shellfish. Further, when the shellfish A passes the position of the rotary grinding body 40 and the external force applied to the claws 43 is removed, each claw returns to its original position, and the same effect is produced each time the shellfishes arrive one after another.

3, the rotary grinding body 40 is prevented from moving in the axial direction, the position of the claw 43 is stable, it rotates at the desired location, there is no fear that the claw 43 will hit the conveyor 10 on both sides, and the position of the shell A is maintained. As mentioned above, since each pawl 43 has different phases and is sequentially shifted in the axial direction, the rotary grinding body 40 rotates once. Ba,
The claws 43 come into contact with the surface of the shellfish A almost without gaps, and have the effect of cleaning the entire area of the shellfish A.

によつても、この調整ができ、歩留まりがよい。 Furthermore, since the rotation axis of the square shaft 45 and the claw guide tube 51 can be mutually changed, the claw guide tube 52 can be moved against the spring force of each spring member 44 to change the movement of the two. By fixing it, the amount of strain given to the spring member 44 in advance can be changed and the repulsive force can be adjusted, and it is also possible to adjust the repulsion force, even when a group of shellfish with a large number of strongly attached objects such as the Fuji pot are attached. ,
A spring force commensurate with this can be obtained. This adjustment can also be made depending on the type of shellfish, resulting in a high yield.
