Description

[Detailed Description of the Invention] The present invention relates to a fish cutter for cutting sardines and mackerel used as feed for aquaculture.

Unlike when cutting vegetables, when the object to be cut has hard bones surrounded by soft meat, such as fish, be careful not to collide with other objects or crush them at the feeding, cutting, and dropping parts. If not, the farmed fish will end up in an oily state that is difficult to ingest, and not only will it be deposited on the bottom of tanks, ponds, and the sea without being ingested, but it will also pollute the water, causing economic and pollution prevention problems. is also preferable.

The present invention was devised in view of the fact that the above-mentioned drawbacks have not been solved with conventional fish cutters or vegetable cutting plates. , the lower end opening of the cylinder 1 is made bottomless and this part is used as an outlet, and bent blades with different rising heights are formed on the left and right sides of the vertical shaft 3 hanging from the center of the upper end of the cylinder 1. The V-shaped cutter 2 is located at the top, and below it a large number of knife-shaped cutters 2' are mounted at predetermined intervals in the axial direction and radially in plan view, and are attached to the inner wall surface of the cylinder 1. is a sliding receiving blade 7 that is compatible only with the V-shaped cutter 2.
is fixed, and furthermore, an input port 5 is opened at the upper end of the cylindrical body 1 at a position above the rotation locus of the cutter.

In the embodiment shown in the figure, a take-out guide 4 is provided at the bottomless opening of the cylindrical body 1, and the take-out guide 4 is inclined to an extent that significantly reduces the collision force and does not impede the bottomless state, and the take-out guide 4 is provided at the bottomless opening of the cylinder 1, and the take-out guide 4 is inclined to an extent that does not inhibit the bottomless state. The upper end of the cylindrical body 1 is closed with a top plate 12 leaving an input port 5, and a vertical shaft 3 is shown penetratingly supported in the center of the top plate 12.

In the figure, 6 is a charging guide whose lower end faces the charging port 5.

The fish cutter configured above has a cutter size of 500 mm.
- Rotate at a speed of ~tooorpm, and add sardines.
It is used to feed fresh fish such as mackerel through the opening of the input guide located at a biased position, cut it inside the cylinder and take it out from the output port. is opened at an eccentric position on the rotational trajectory of the cutter, so that the fresh fish thrown in will not fall directly near the free end of the cutter, which has a high rotational speed, rather than near the rotating part, which has no or poor cutting ability. Becomes disconnected.

In addition, the cutters are V-shaped and knife-shaped and are axially mounted at predetermined pitches in the axial direction and radially when viewed from above, so that (1) the fresh fish is not cut into small pieces, but is cut appropriately.

This is because if a large number of blades radiating from the same plane are arranged in the axial direction, each blade will surely cut the fish into small pieces, but with the above-mentioned configuration of the present invention, the first blade Sometimes it is only cut by the third piece, or it slips through and is cut only by the second and fourth pieces.
This will result in an extremely rough cut.

In particular, a V-shaped cutter is provided at the top, as well as a sliding receiving blade that corresponds only to this cutter, so that the fish thrown in will be reliably cut without being thrown upwards, and will be pulled downwards. Because of this, ■The fish that has been put in can be cut smoothly without pooling near the bottom of the inlet.

Furthermore, since the cylindrical body is bottomless or the take-out port is formed through a take-out guide inclined from the bottomless part, ■ the cut fish falls directly onto the cut fish or via a take-out guide with a small collision force; The cut fish can be taken out without being crushed.

The fish fed through the cooperative synergistic effects of (1), (2), (2), and (3) above can be used as food for aquaculture fish of an appropriate size that will not be crushed.

Therefore, the intake effect is good and economical, and water contamination due to wet and crushed bait or uningested bait is significantly reduced, contributing to pollution prevention.
