Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a purifier for removing deposits adhering to the surface of shells of shellfish such as scallops and oyster shellfish.

(Conventional technology and its problems) This kind of shell surface cleaner
There is one described in Publication No. 43676.

The bottom surface of the shellfish movement passage provided in the frame body is on the same level from the entrance to the exit (the bottom surface is in a straight line), so when removing deposits from the surface of the shell, the bottom surface of the shellfish is cut below the center. Adjust the cutting blade accordingly. However, since the shellfish supplied to the shellfish moving passage are rotated and moved by the shellfish extrusion rotating belt, cutting by the cutting blade is performed radially from the center of the shellfish, and the central part of the surface of the shellfish is cut more than necessary. cutting wear. By the way, the hardness of seashells is such that the surface skin is hard and becomes softer as it goes inside the shell. Therefore, as mentioned above, when the central part of the shellfish is cut more than necessary, a soft layer appears, which makes it easier for parasites (Polydora) to invade the inside of the shell during aquaculture and rearing when the shellfish is put back into the sea after the deposits are removed. When a parasite (Polydora) invades the shell, it eats through the shell and creates a tunnel-like hole that harms the growth and reduces the commercial value of the shell.

(Purpose of the invention) In view of the above-mentioned conventional circumstances, it is an object of the present invention to provide a cleaner that uniformly removes deposits from the shell surface and does not cause excessive cutting wear.

(Structure of the invention) The technical means taken by the invention to achieve the above object is to make the bottom surface of the shellfish moving passage with a substantially V-shaped cross section attached to a pedestal as a straight section on the same level from the entrance to the vicinity of the exit. , the structure is such that it is gradually inclined downward from near the exit toward the exit.

(Function) According to the above configuration, by adjusting the cutting blade so that the cutting is performed from a portion slightly outward from the center of the shellfish, the shellfish is cut during the movement in the straight line from the entrance to the vicinity of the exit. Cutting is performed radially from a point slightly outward from the center, and as the bottom surface is lowered while moving from the vicinity of the exit to the exit, the point where the cutting blade comes into contact is near the center of the shell, and the entrance The surface of the shellfish is cut almost uniformly by the movement from the point to the outlet.

(Embodiment) Hereinafter, embodiments of the present invention will be described based on the drawings. Reference numeral 1 indicates a pedestal, 2 a comb-shaped shell moving passage with a substantially V-shaped cross section and a comb-like shape attached to the pedestal 1; a shellfish extrusion rotating belt arranged at the upper part of the shellfish moving passage 2 and rotating from one end (inlet) to the other end (exit);
4 and 4' are cutting blades arranged on both the left and right sides of the shellfish moving passage 2, which cut the shellfish extruding rotating belt 3 inside the shellfish moving passage 2.
The surface of the shell of the shellfish 8 which is rotated and moved by the operation of is cut to remove deposits.

The shellfish moving passage 2 has rods 6 on both left and right sides of the frame 5.
are fixed at appropriate intervals, and the lower ends of the left and right bars 6 are joined and fixed to form a passage having a substantially V-shaped cross section.
A cutting blade window 7 into which the blade 4' fits is formed.

The bottom surface of the shellfish moving passage 2 is formed with a linear portion a on the same level from the entrance to the vicinity of the exit, and the bottom surface of the portion from the vicinity of the exit to the exit is formed as an inclined portion b that gradually slopes downward.

With the above configuration, the cutting blades 4, 4' are cut radially from a location on the outside of the center of the outer surface of the shellfish 8 in the moving portion of the straight line a of the shellfish moving path 2 (see Fig. 3). By adjusting this so that the center of the shell 8 is lowered while the inclined part b is moving, the center part that was not removed during the movement of the straight part a is cut while the inclined part b is moving (see FIG. 4). As a result, the shell 8 can be cut almost uniformly, and the central part will not wear out more than necessary. This makes it possible to perform cuttings that can prevent the invasion of parasites. Note that the left and right bars 6 constituting the shellfish moving passage 2 are not limited to the illustrated form in which they are fixed to each other facing each other, but the left and right bars 6 may be arranged alternately.

(Effects of the invention) As detailed above, the shell surface cleaner of the present invention has a straight line section on the same level from the entrance to the vicinity of the exit on the bottom of the shell moving passage, and gradually slopes downward from the vicinity of the exit toward the exit. Therefore, while moving in a straight line from the inlet to the vicinity of the outlet, the outer part of the shell surface excluding the central part is cut radially, and while moving in the inclined part from near the outlet to the outlet, the outer part of the shell surface is cut radially. The central part of the blade is cut to ensure uniform cutting.

Therefore, excessive cutting does not occur in some parts, and ease of invasion by parasites can be prevented.
