Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a cutting machine for cutting frozen feed for fish culture, especially a cutting machine for making food suitable for feeding larvae that have grown to about 12 cods in length after being acetylated. It is related to.

[Conventional technology]

The artificially hatched larvae are raised on rotifers and plankton for the first 30 to 40 days, but when they reach about 12 cods in length, they are initially fed fish. The best bait at this time is fish fillets from 0.5 m square to 1 cod square. Frozen feed is generally used for fish farming, and this frozen feed is made by freezing fish such as sardines and saury in a box.

Such frozen feed is transported from the frozen warehouse to the fishing grounds in refrigerated trucks, thawed, and then cut into pieces using cutters, choppers, mincing machines, etc., and administered to fish farms. Since it is not possible to make them, the fish tanks used for raising larvae are fed with ground food using a mincing machine.

[Problem that the invention seeks to solve]

If you put the above-mentioned ground bait into an aquarium, the water in the aquarium will become cloudy, and nutrients will flow into the water, causing the water to rot.

Therefore, it is necessary to constantly replace the water in the aquarium, which may cause the water quality to change suddenly or the water temperature to change, which requires adjustment.

Therefore, dry bait is sometimes used, but this dry bait has problems with floating and sinking when administered, and the swallowed bait absorbs water in the fish's vagina and swells, causing oxygen deficiency and leading to death. There is also.

Also, when the fish reach the intermediate stage of growth between 3 and 8 inches in length, they will be raised in the sea, but if minced bait like the one mentioned above is used, the bait will stick to the fish as it breathes and rot, causing gill disease.
Problems arise such as vitamin B1 being destroyed and fat denaturing into peroxidized fat due to the outside air, causing fish diseases.

In addition, in the case of frozen feed, yellowtail fed with unthawed food has stronger resistance than yellowtail fed with thawed food, and even if they develop the disease, they are more likely to recover. It has become clear that.

For this reason, methods have been considered to crush the frozen fish into pieces without waiting for them to thaw and then administer them either as is or by using a chopper or mincer to make them even finer. Currently, there is no ice crusher that can crush ice well and safely.

In order to solve the above problem, the present inventor first filed a patent application in 1983.
-201699 and Utility Application No. 59-177154, we proposed a frozen feed ice crusher and its blades.

Although this ice crusher is excellent in that it can crush frozen feed very efficiently, it has the problem of not being able to obtain fine ice that is suitable for use as feed for young fish that have recently been acetylated.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention fixes replaceable blades to at least two locations on the circumferential wall of a hollow rotating drum driven by an appropriate driving means via replaceable shims. The cutter is configured to cut the frozen bait that is sent toward the target, and the surface of the cutter is provided with a plurality of grooves in the direction of rotation, and the grooves between them are used as cutting blades, so that the frozen bait can be cut to an appropriate width. At the same time, the cutting edge of the cutter is placed at different positions so that the front part of the frozen bait can be cut evenly, and the back surface of the cutter is bent by the crease, so that the cut bait can be broken by the cutting blade. This is what I did.

[Effect]

This invention has the above configuration, and when the frozen bait is pushed toward the outer periphery of the rotating hollow drum, the uneven cutter fixed to a part of the opening of the drum scrapes off the frozen bait. The creases formed on the inside of the knife break it into pieces, which are then discharged into the chute.

However, the last bait 43 can be completely cut by placing the additional push frame 41 shown in FIG.

〔effect〕

Since the cutting machine of the present invention cuts the frozen bait using a cutter provided on the peripheral wall of the rotating drum, the frozen bait can be cut into extremely thin pieces. Moreover, the cutter has multiple grooves, and the cutting edge is between these grooves, so the frozen bait is cut thin and wide, and the cutting edge is provided at multiple locations on the peripheral wall of the drum. Due to the different positions, the front side of the bait is cut evenly.

Further, the back surface of the cutter is bent at the folds, and since the cut bait is still frozen and hard, it will break if bent at the folds. Therefore, the frozen feed is discharged in the form of extremely fine fillets, so that the optimum feed for young fish can be obtained.

In addition, you can change the shim to adjust the protrusion of the cutting edge,
By selecting and installing blades with cutting edges of different widths, it is possible to adjust the size of the cut feed according to the growth of the larvae.

In addition, when the horizontal type is used as in the example, the cutting is done crosswise, which reduces the load on the drum and saves power, and since the cutting is done in an arc shape, the frozen feed sticks to the drum and becomes stable. However, since there is no vibration, a thin bait bag with a uniform thickness can be obtained. Further, since the work surface is around the waist of the worker, the work becomes easier.
