Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cutter suitable for removing shellfish adhering to the surface of, for example, bivalves.

(Prior Art) Other shellfish such as crow shells and barnacles tend to adhere to the surface of bivalves such as Akoya shellfish used for aquaculture, and if this is left as is, the growth of the cultured shellfish will be impaired. Therefore, the surface of cultured shellfish is pressed against a rotating disk-shaped cutter to cut off and remove any deposits such as other shellfish attached thereto.

This type of cutter has a disc with a large number of wart-shaped cutting blades protruding from its rotating circumferential surface, which is fixed to a rotating body. This cutter has a rotating body and a cutting blade that are integrated, so when you hold the bivalve in your hand and press the cutter to remove the deposits, the bivalve receives a direct reaction, which causes a large amount of damage to the shell itself. Not only were the vibrations transmitted and adversely affected, but the recoil often accidentally scratched or damaged the shellfish. Furthermore, since the shape of the cutting blade is determined to be one type, it is not possible to use cutting blades with different shapes depending on the size of the cultured shellfish and the type and size of the deposits.

(Problems to be solved by the invention) The present invention has been made in view of the above circumstances, and
To provide a cutter that absorbs the reaction against the shellfish when pressing the shellfish against the cutter and allows cutting blades of different shapes to be used in combination as required.

(Means for Solving the Problems) In order to solve the problems of the conventional art, the present invention includes a laminated ring group, a cutting blade group, a ring groove formed in each laminated ring, and a ring groove formed in each cutting blade body. It is characterized by comprising a cushioning material interposed between the recess and the recess.

The laminated ring group is constructed by concentrically stacking a plurality of rings each having a plurality of ring grooves formed on the outer periphery so as not to rotate.

The cutting blade group has a plurality of cutting blades protruding from the outer periphery, a circular hole in the center in which the ring can be positioned with a gap, and each of the rings on the inner periphery of the circular hole. A cutting blade body provided with a concave portion corresponding to the concave groove is positioned corresponding to each ring.

Furthermore, by stacking and fixing a plurality of rings with their phases shifted by a predetermined angle, the cutting blades of the cutting blade group corresponding to the rings are arranged in a staggered manner.

(Function) According to the above configuration, when pressing the ingredient against the cutter, the reaction force received by the shellfish can be absorbed by the cushioning material, and by stacking and fixing cutting blades with different shapes, several types of cutting blades can be used. can be used in combination.

(Example) Examples of the present invention will be described below based on the drawings. In FIGS. 1 and 2, 1 is a side plate of the cutter, and a shaft barrel 2 is protruded from the center of one side of the side plate 1, and an insertion hole 2a for the rotating shaft of a drive source such as a motor is provided at the shaft center. is formed through it. As shown in FIGS. 2 and 3, the shaft barrel 2 has a shaft hole 3 in the center, and a plurality of substantially semicircular ring grooves 4 arranged at equal intervals on the outer periphery.
A plurality of rings 5 (five in this embodiment) each having a ring 5 formed thereon are stacked and fixed to the shaft body 2 through the shaft hole 3 such that the ring grooves 4 of each ring 5 are out of phase at a predetermined angle. and constitute a stacked ring group.

The means for shifting the phase of the ring grooves 4 of each ring 5 by a predetermined angle does not need to be particularly limited, but, for example, it may be attached to a semicircular groove 6 carved in one end of the shaft barrel 2. As shown in FIG. It is sufficient to insert and fix it by sliding it so that it cannot rotate.

On the outer periphery of each ring 5, the same number of cutting blade bodies 10 as the rings 5 having the same shape and each having a large number of cutting blades 9 protruding from the circumferential surface at equal intervals are attached.
As shown in FIG. 4, each cutting blade body 10 is provided with a circular hole 11 whose diameter is slightly larger than the diameter of each ring 5.
A plurality of approximately semicircular recesses 1 corresponding to the ring grooves 4 of each ring 5 are provided on the inner circumferential surface of the circular hole 11.
2 is formed. And these cutting blade bodies 1
As shown in FIGS. 5 and 6, when the ring 5 is inserted into the outer circumference of each ring 5 inserted into the shaft body 2, urethane, rubber, etc. A donut-shaped cushioning material 13 made of an elastic material such as the above is interposed, and a constant gap 14 is formed between the outer circumferential surface of the ring 5 and the inner circumferential surface of the cutting blade body 10. Since the rings 5 are stacked and fixed at different angular phases, as shown in FIG. 7a,
The cutting blades 9 of each cutting blade body 10 are positioned sequentially shifted by a predetermined angle. For example, when each ring 5 and each cutting blade body 10 are combined, FIGS.
As shown in the figure, six ring grooves 4 are formed by sequentially setting the phase difference between the ring grooves 4 of each ring 5 to 7.5 degrees, and the deviation angle of each cutting blade 9 is set to 7.5 degrees, respectively, to form the cutting blade body 10. By setting the number of each cutting blade 9 to 24, as shown in FIG. 7a, the straight cutting blades 9 of adjacent cutting blade bodies 10 can be arranged in a staggered manner.

In addition, 15 is a cover plate, which is fixed to the end face of the shaft body 2 of the side plate 1 with a countersunk screw 15a to connect the side plate 1 and the cover plate 15.
Each ring 5 and each cutting blade body 10 are held in between.

Figures 7b and 7c show other embodiments of the cutting blade; while the cutting blade shown in Figure 7a is straight, Figure 7b shows a spiral cutting blade 9a that is inclined to the right. A cutting blade group is constituted by alternately arranging the left-inclined spiral cutting blades 9b in a staggered manner. FIG. 7c shows a combination of a straight cutting blade 9 and spiral cutting blades 9a and 9b, forming a cutting blade group in which adjacent cutting blades are arranged in a staggered manner. In addition, the arrangement and combination of the cutting blade bodies can be freely set other than the above example as necessary.

FIGS. 8 and 9 show an example in which the cutter according to the present invention (in the example, the cutter shown in FIG. 7a) is applied to a device for removing deposits on the surface of bivalve molluscs.

The insertion hole 2a of the cutter A is inserted into the rotating shaft 16 and fixed with a nut 17, and the rotating shaft 16 is held through the bearing part 18, and the bearing part 18 is supported by the arm 19. A bearing plate 22 is mounted on the machine frame 21 so as to be able to rotate vertically (FIG. 9) using the support portion 20 at the base end as a fulcrum.
It is supported by 22. The upper end of a shaft 23 is held in the middle of the arm 19, and the machine frame 21 is attached to the shaft 23.
A stopper 24 is provided at the lower end of the
Between the arm 19 and the machine frame 21 and the machine frame 2 on the shaft rod 23
Coil springs 25a and 25b serving as cushioning means are stretched between the stopper 1 and the stopper 24, respectively.
This allows the arm 19 to be held in a cushioned manner. A pulley 26 is provided at the other end of the rotating shaft 16, and a belt 29 is wound around the pulley 26 and an output shaft 28 of a motor 27. 30 is a rotation speed variable device for the motor 27.

Next, the operation will be explained. When the motor 27 is started, the cutter A is rotated via the belt 29, and then the cutter A is rotated as shown by the imaginary line in FIG.
A cultured shellfish 31 held by hand is brought close to the shell from below, and the attachments 32 such as crow shellfish adhering to the surface of the shellfish are pressed against the cutting blade 9 to be cut and removed. At this time, by pressing the deposit 32 against the cutting blade 9, the cutter A is caused to spring against the coil springs 25a, 25a and 25a according to the pressing force.
5b is pushed up against the spring force, and the vibrations received by the cutting blade 9 are caused by each buffer material 1 of each cutting blade body 10
3, each cutting blade body 10 can absorb it independently within the gap 14, thereby suppressing large vibrations and recoil caused by cutting to the shellfish itself, and making it possible to effectively remove deposits. . The shape and combination of the cutting blades of the cutter can be freely changed depending on the size of the cultured shellfish and the type and shape of the attached materials.By removing the countersunk screws 15a and removing the cover plate 15, each cutting blade body 10 can be changed. It can be attached and detached.

Although the cutter of the present invention has been described as an example in which it is used in an apparatus for removing deposits on the surface of shellfish, it can be widely applied to other cutters that require cutting.

(Effects of the Invention) As described above, according to the present invention, a cutting blade group is provided in which a cushioning material is interposed on the outer periphery of each of the laminated ring groups inserted in the shaft barrel, and cutting blades are protruded from the outer periphery. With this structure, there is little vibration or reaction to the object to be cut, and it is possible to prevent scratches on the surface of the shellfish when removing various deposits attached to the shellfish.

Furthermore, since cutting blades of different shapes can be freely combined as needed, various deposits attached to the surface of the bivalve can be effectively removed.
