[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device for cutting block-like frozen feed for cultured fish, which is made of feed such as sardines and mackerel, into diced patterns.

[0002]

2. Description of the Related Art Sardines, mackerels and the like, which are used as feed for cultured fish, are usually instantly frozen, sterilized and frozen in a block state. Therefore, when feeding the cultured fish, it is necessary to cut the block-shaped frozen bait into a predetermined size according to the type and size of the cultured fish.

The applicant of the present application has already proposed a cutting device for dicing block-shaped frozen bait (Japanese Patent Publication No.
16536).

In the cutting device described in the above publication, the movable blade plate is moved up and down with respect to the fixed receiving blade to cut the block-shaped frozen bait inserted between both blade plates in the width direction, and Brick-shaped frozen bait formed by cutting is pressed against a plurality of fixed blade plates arranged in parallel by a movable pressing blade to cut it into diced shapes.

[0005]

By the way, in the cutting device described in the above publication, since the block-shaped frozen bait is diced by the reciprocating movement of the movable blade plate and the movable pressing blade, the processing capability is improved. Is low and there is a problem that noise is generated.

[0006] An object of the present invention is to provide a cutting device which can cut a frozen frozen bait in a block shape very efficiently with a small amount of noise.

[0007]

In order to solve the above-mentioned problems, in the present invention, a chute arranged in an inclined shape with a gradient toward the tip, and a block-shaped frozen bait supplied on the chute. A feeding device that conveys the tip toward the tip of the chute while pressing and the tip of the frozen bait protruding forward from the tip of the chute by the blade plate attached to the outer periphery that is rotatably driven in one direction disposed in front of the chute. A rotary cutter that cuts in the width direction to form a brick-shaped frozen bait, and a pair of rotary cutters that are arranged below the rotary and are driven to rotate in the direction in which the brick-shaped frozen bait is wound between the facing portions. And a fixed blade disposed below the pair of rotary cutters, wherein the rotary cutter is arranged in parallel with the rotary cutter and has a plurality of cutting blades extending in the radial direction of the rotary shaft. A plurality of blade plates having a required interval is attached, the fixed blade has a plurality of blade plates having a cutting blade on the upper side, with an interval at which the cutting blade of the rotary cutter can pass. The configuration adopted is that the rotary cutter is arranged in the axial direction.

[0008]

In the cutting device having the above-mentioned structure, the block-shaped frozen bait supplied on the chute is fed toward the lower part of the inclined part of the chute by the feeding device, and the frozen bait protruding forward from the tip of the chute is fed by the rotary cutter. Cut across the width to form a brick-like frozen bait. The frozen bait is cut by rotating the pair of rotary cutters in opposite directions, and the frozen bait is pressed against the fixed blade by the pair of rotary cutters and cut into diced pieces.

A tubular body 17 is attached to the outside of the drum shaft 14 between the pair of flanges 15.

Here, a V-shaped guide surface 18 is formed on the outer periphery of the body 17 facing each blade plate 16. The guide surface 18 has a function of smoothly discharging the brick-shaped frozen bait A ′ below the rotary cutter 13 when the brick-shaped frozen bait A ′ enters between the body 16 and the blade plate 16.

Below the chute 3 and the rotary cutter 13, an intermediate sheet 19 for guiding the fall of the brick-shaped frozen bait A'formed by the rotary cutter 13 is provided.

As shown in FIG. 3, the intermediate chute 19 is provided with a plurality of guide pieces 21 extending long in the inclination direction of the support plate 20 at the tip end of the support plate 20 which is arranged in an inclined shape with a downward slope toward the tip. The support plates 20 are arranged at equal intervals in the width direction.

A pair of rotary cutters 22 are provided in front of the intermediate chute 19 and below the rotary cutter 13.
a and 22b are provided at the front and rear, and a pair of rotary cutters 2

As shown in FIG. 5, the fixed blade 23 has a structure in which a plurality of vertically oriented blade plates 29 are provided at equal intervals in the lengthwise direction of a horizontally oriented blade plate 28. A cutting blade 30 is provided on the edge.

In the fixed blade 23, the horizontal blade plate 28 is parallel to the rotary shaft 24 of the rotary cutters 22a and 22b, and the cutting blades 26 of the rotary cutters 22a and 22b can rotate between the vertical blade plates 29. It is supposed to be arranged.

Reference numeral 31 denotes a discharge port provided on the lower side of the other side of the casing 1.

The cutting device shown in the embodiment has the above structure, and its operation will be described below.

Now shoot 3 blocks of frozen bait A
When it is supplied to the top, the frozen bait A is pressed by the engagement of the feed claws 9a formed on the plurality of feed plates 9 of the feeding device 5, and is fed toward the tip of the chute 3 by the rotation of the feed plate 9.

If the thickness of the frozen bait A is thicker than the distance between the feed claw 9a at the lower outer periphery of the feed plate 9 at the lowest position and the upper surface of the chute 3, the frozen bait A passing under the feed plate 9 is thickened. By this, the feeding device 5 is lifted upward, and the weight of the feeding device 5 acts on the frozen bait A, and the floating of the frozen bait A is prevented.

The frozen bait A is the transmission 1 of the feeding device 5.
It is sent at a feed rate corresponding to the rotation speed of 1. For this reason,
By adjusting the rotation speed of the transmission 11, the feed amount can be arbitrarily adjusted.

When the front end of the frozen bait A projects forward from the front end of the chute 3, the front end of the frozen bait A is rotated by the rotary cutter 13.
Brick-shaped frozen bait A'is formed by cutting the blade plate 16 in the width direction.

The width dimension of the brick-shaped frozen bait A'correlates with the feed amount of the feeding device 5, and when the feed amount is small, the width dimension is small, and the width dimension increases as the feed amount increases.

The brick-shaped frozen bait A'may fall downward along with cutting, or may enter between the blade plate 16 of the rotary cutter 13 and the guide surface 18 of the body 17, and the falling one is intermediate. It drops onto the chute 19, slides down along the inclination of the intermediate chute 19, is scraped up by the blade plate 25 of the one rotary cutter 22a, and is fed between the opposing parts of the pair of rotary cutters 22a and 22b.

On the other hand, the brick-shaped frozen bait A ′ that has entered between the blade plate 16 and the guide surface 18 of the rotary cutter 13 is conveyed in the circumferential direction by the rotation of the rotary cutter 13, and the blade plate 16 is located below the outer periphery of the rotary cutter 13. When passing through the blade plate 16, a pair of rotary cutters 22a, 2
It falls between 2b.

The brick-shaped frozen bait A'invaded between the pair of rotary cutters 22a and 22b is the rotary cutters 22a and 2b.
It is cut by the cutting blade 26 formed on the blade plate 25 of 2b, pushed down, and further cut by the horizontal blade plate 28 and the vertical blade plate 29 of the fixed blade 23 to be diced and discharged from the discharge port 31. It

[0036]

As described above, in the cutting device according to the present invention, the block-shaped frozen bait which is supplied on the chute and sent forward is diced by the rotation of the rotary cutter and the rotation of the pair of rotary cutters. Since the block-shaped frozen bait is cut into pieces, it is possible to cut the frozen bait in a very efficient manner and to suppress the generation of noise.

Further, since the frozen bait is pressed forward by the feeding device provided on the chute,
The rotary cutter can surely cut the frozen bait.

Furthermore, the frozen bait can be cut into an arbitrary size by using the feeding device whose feed amount can be adjusted.
