Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for cutting fish bodies such as saury used as bait in longline fishing.

[Prior art and its issues] In general, when catching walleye cod etc. by longline fishing, the size of the bait is changed in 1 mm increments within the range of 10 to 15 mm depending on the sea area and growth. There is. For this reason, if the sliced fish body is cut diagonally and the size varies, it may affect the catch.

As a means to solve such problems,
A fish body cutting machine as shown in Publication No. 50-3898 has been proposed, but this machine receives fish bodies that have slid down a chute with an impeller, and presses them against a number of disk cutters arranged side by side. This cutter is designed to cut the fish body into small rounds, but when the cutting resistance of the disk cutter is large and it is difficult to cut, an excessive load is applied to the impeller, which may damage the disk cutter or the impeller. Significant issues remain.

The present invention was developed in view of these circumstances, and it solves the problems of the conventional technology through simple and rational means, and mechanically obtains food of a size suitable for the sea area and growth. It is an object of the present invention to provide a fish body ring-slicing device that can improve fishing efficiency.

[Means for Solving the Problems] The configuration of the present invention, which solves the problems of the prior art, has two shafts that rotate in opposite directions mounted in parallel inside the box-structured fuselage. is provided with a plurality of disc blades, and a disc body for feeding the fish body is provided on the other shaft, each disc body is interposed between the disc blades, and above the group of disc bodies,
In the fish body cutting device provided in the above-mentioned body and facing the fish body input port for inputting fish bodies in a horizontal position, each of the above-mentioned disk bodies is symmetrically formed with mutually matching fish body holding notches, A semi-circular fish body receiving edge is formed between the notches, a gap between this fish body receiving edge and the lower surface of the fish body inlet is made smaller than the thickness of the fish body, and the shaft on which the disk body group is provided is made to It is characterized in that it is connected to a drive mechanism via a clutch structure.

[Embodiment] To explain the details of the embodiment of the present invention with reference to the drawings, 1 is a rectangular plane shape and a box-shaped body, and an outer end of the body 1 is located above the interior of the body 1. A shaft 2 that rotates at high speed and has a flywheel 2a on its part and a shaft 3 that rotates at low speed are parallel to each other.
Moreover, the shafts are mounted on the same plane. Further, as shown by the arrows in FIG. 1, the shafts 2 and 3 have opposite rotation directions and a polygonal cross-sectional shape.

The shaft 2 that rotates at high speed has a plurality of disk blades 4.
are attached at appropriate intervals. As a means for attaching the disc blade 4 to the shaft 2, a polygonal hole having the same cross-sectional shape as the shaft 2 is formed at the center of the disc blade 4,
The shaft 2 is inserted into this hole. Also, the second
As is clear from the figure, the starting end positioning pipe 5 of the disc blade 4 is fixed to one end of the shaft 2 by means such as welding, and the distance between each disc blade 4 is determined by the length of the interval between the disc blades 4 inserted into the shaft 2. It is determined by the partition pipe 6. When adjusting the distance between each of the disc blades 4,
A spacer (not shown) having a width in mm units is interposed between the partition pipe 6 and the disc blade 4, so that the distance between the disc blades 4 can be arbitrarily set and adjusted within the range of 10 to 15 mm, for example. It is. 7 is a terminal pipe which is tightened and fixed with a nut 8 screwed onto the shaft 2 to prevent each disk blade 4 from moving in the axial direction. 9 is a motor that drives the shaft 2 that rotates at high speed; the motor 9 and a pulley 10 provided at the end of the shaft 2;
and are connected by a belt 11.

The shaft 3 that rotates at a low speed also has a polygonal cross-sectional shape similar to the shaft 2 that rotates at a high speed, and a plurality of disk bodies 12 are inserted into this. As a means for attaching each disc body 12 to the shaft 3, a polygonal hole having the same cross-sectional shape as the shaft 3 is formed in the center of the disc body 12, and the shaft 3 is inserted into this hole. Further, as shown in FIG. 2, a starting end positioning pipe 13 of the disc body 12 is fixed to one end of the shaft 3 by means such as welding, and furthermore, the interval between each disc blade 12 is determined by the distance between the disc bodies 12. This is determined by the boss 12a or by a partition pipe (not shown). When adjusting the distance between the discs 12, a spacer (not shown) having a width in millimeters is used to adjust the spacing between the discs 12 so that they are located in the center between the disc blades 4. In the figure, 14 is a terminal pipe, and 15 is a nut.

As is clear from the figure, between each disc body 2,
This is to allow the disk blade 4 to intervene deeply. Each disc body 12 is provided with fish body holding notches 12b having a U-shaped front face symmetrically with an interval of 180 degrees.
The disc body 12 is attached to the shaft 3 so that b coincides with each other without shifting. Both notches 12b of the disc body 12
In between, there is a relatively long semicircular arc-shaped fish body receiving edge 12c.
form. Further, the peripheral edge portion of the disc blade 4 is
It is located further inward from the deepest part of the notch 12b of the disk body 12, so that no uncut portion of the fish remains. Further, at the outer end of the machine body of the shaft 3 that rotates at a low speed, a rotating body 1 is provided with a friction ring 16 on the outer surface.
At the same time, a pulley 18 is inserted into the shaft 3 on the outside of the rotating body 17, and a spring 19 is elastically loaded between the outer surface of the pulley 18 and the end of the shaft 3, so that the inner surface of the pulley 18 is fixed. The friction ring 16
to form a friction clutch structure. Then, this pulley 18 is connected to the shaft 3 via the belt 20.
is connected to a motor 21 that rotates at a low speed, and when the load resistance when the fish caught in the notch 12b of the disc body 12 group is pressed against the disc blade 4 group exceeds the set load, the pulley 18 and A slip is generated between the shaft 3 and the friction ring 16 to stop the rotation of the shaft 3, thereby preventing damage to the cutting mechanism such as the disc body 12 and the disc blade 4 due to overload.

As shown in FIGS. 1 and 2, 22 is a rod-shaped scraper that is inserted vertically between the disc blades 4 and has the function of causing the cut fish body to fall downward from between the disc blades 4. As shown in FIGS. 4 and 5, pipes 23 made of rubber or the like are fitted into the upper ends of the rod-shaped scrapers 22, respectively. Reference numeral 24 denotes a tightening fitting for the rod-shaped scraper 22, and both ends of the tightening fitting 24 are fixed to the body 1. Each of the rod-shaped scrapers 22 is connected to this clamping metal fitting 24 and another clamping metal fitting 2 that is attached to the clamping metal fitting 24 with a tightening bolt 25.
6, and the bar-shaped scraper 22 can be freely moved in the horizontal direction by loosening the tightening bolt 25. Further, as shown in FIG. 1, the upper end of a safety cover 27 that covers approximately half the circumference of the disk blade 4 is fixedly attached to the tightening fitting 24.

28 is a chute installed diagonally at the bottom of the fuselage,
Partition plates 29a and 29b parallel to the disk surface are vertically provided on the left and right sides of the upper surface of the chute 28, specifically, below the disk body 12 at the left and right ends, and one of the partition plates 2
The head of the fish cut off onto the chute 28 on the outside of the partition plate 9a and the tail of the cut fish on the chute on the outside of the other partition plate 29b are dropped and collected separately, and Both partition plates 29
The sliced body of the fish body is dropped onto the chute 28 between a and 29b and collected, so that the sliced body, head, and tail can be collected without being mixed together.

30 is a cover plate attached to the upper part of the body 1 so as to be openable and closable, and the cover plate 30 has the disk body 12
For example, a fish body inlet 31 into which a saury can be inserted in a horizontal position is provided in the part facing the fish body, and the lower end of this fish body inlet 31 is placed close to the circumferential surface of the disc body 12 at a distance smaller than the thickness of the fish body. The saury accommodated in the fish body inlet 31 is successively inserted and held in the notch 12b of the disc group starting from the one at the bottom.

[Description of action] Next, the action will be explained. For example, when saury serving as food is thrown in one after another in a horizontal position from the fish body inlet 31, the lowest saury is fed by the fish body receiving edge 12c which is the circumferential surface of the disk body 12 group. The fish body is temporarily caught, corrected to the correct posture, and then dropped into the rotating notch 12b for holding the fish body, transported in the direction of the arrow, and held at a predetermined pitch by the disc blade 4. Sliced into rounds. The rod-shaped scraper 22 inserted into each disk blade 4 causes the disk to fall off downward, and the chute 28 and
The head, body, and tail are sorted and collected by the action of the partition plates 29a and 29b.

Furthermore, when the fish body is frozen and hard, or bones are hard, and a load higher than the set value is applied to the disc blade 4, a slip occurs between the friction ring 16 and the pulley 18, and the shaft 3, that is, the disc body 12 is stopped, the fish body is gradually cut by the disk blade 4, and when the cutting of the hard part is completed, the disk body 12 automatically returns to normal rotation again.

In addition, when adjusting the size of the fish to be sliced into rings, a spacer is interposed between the disc blades 4 and a spacer is interposed between the disc bodies 12, and the movement of the rod-shaped scraper 22 is adjusted accordingly. It is.

[Effects of the invention] As described above, according to the invention, the following effects can be obtained.

(a) It goes without saying that the fish (saury) can be automatically and continuously cut into rounds; (b) each disc arranged at appropriate intervals is provided with notches for holding the fish; Since a relatively long semi-circular fish body receiving edge is formed in between, this fish body receiving edge allows the posture of the fish to be corrected and the fish body to be held in the notch, allowing accurate round cutting of the fish body. Therefore, bait of a size suitable for longline fishing can be obtained continuously, and fishing efficiency can be improved.

(c) Since the shaft on which the disc group is provided is connected to the drive mechanism via the friction clutch structure, when a load higher than the set value is applied to the shaft of the disc, the rotation of the shaft is controlled by the friction clutch structure. It stops due to the action of the body, and damage to the disc blade and disc body mechanism due to overload can be reasonably prevented.
