Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a chopper for cutting fish meat, etc., and more particularly to a chopper cutting device for producing granular feed for fish and poultry farming.

BACKGROUND TECHNOLOGY In general, as shown in Fig. 2, a chopper consists of a body 1 having a built-in screw (not shown) for pumping raw materials, and a body 1 formed on the body 1.
It consists of a hopper part 2 into which raw materials such as pork are fed, and a gearbox 3 which transmits power from a drive source (not shown) to the screw. A cutting device A is provided.

In FIG. 3, numeral 4 is fixed in the body 1 by a key 5, and has a plurality of through holes 6, 6 having a predetermined shape.
The plate 7 on which... is formed is a rotating shaft passing through the center of the plate 4, and is connected to the screw. 8 is on the back side of the plate 4,
A substantially cross-shaped first cutter is fixed to the rotating shaft 7, and the cutting edges 8a, 8a... of the first cutter 8 are on the side facing the plate 4, and the rotation of the first cutter 8 is It is provided on the edge on the direction side. Reference numeral 9 denotes a substantially cross-shaped second cutter disposed on the surface side of the plate 4 in a state fixed to the rotating shaft 7, and the cutting edge 9 of this second cutter 9
a, 9a, . . . are provided at the edge of the second cutter 9 on the side facing the plate 4 in the rotational direction. In addition, the first and second cutters 8, 9
The cutting edges 8a, 8a..., 9a, 9a... are in sliding contact with the back surface or the front surface of the plate 4, respectively.

The above-mentioned chopper uses a screw that rotates raw materials such as fish meat and pork fed into a hopper section 2 via a gearbox 3 by a drive source (not shown) to force feed the raw materials inside the body 1 toward the cutting device A. The raw material is pushed into the through holes 6, 6... of the plate 4, cut by the first cutter 8 by rotation of the rotating shaft 7 connected to the screw, and the cut raw material is further passed through the through holes 6, 6... At the time of extrusion, the second cutter 9 cuts the product into predetermined lengths to obtain granular products.

The above-mentioned granular products are manufactured in various types depending on their dimensions, particle diameters, raw materials, etc., and these products are supplied to the market as granular feed, granular fertilizer, and the like.

Problems to be Solved by the Invention In recent years, in the marine aquaculture industry for yellowtail, silver salmon, etc., granular products made mainly of fish meat and the like have been frequently used as feed.

Considering the digestibility, growth, etc. of farmed fish, this type of granular product is preferably a moist product with a relatively high moisture content, using raw small fish as the main raw material.

However, the conventional chopper cutting equipment mainly only cuts raw materials into small pieces, and since the degree of bonding is low, especially in wet products such as those mentioned above, when this granular product is administered to the sea surface, it easily breaks down in the sea. However, when used as actual feed for farmed fish,
At the same time, the problem arises that the seawater becomes polluted.

Therefore, there is a need for the development of a chopper cutting device that can produce highly bonded granular products that are difficult to decompose in water.

Means for Solving the Problems The present invention has been made in view of the above-mentioned problems, and is provided with a first coarse grinder having a predetermined shape and number of through holes, which is disposed at the back of the body of the chopper. a plate, and a second plate for forming product particle size, which is disposed on the front side of the body and has through holes of a predetermined shape and number.
The first plate is fixed to a rotating shaft that rotatably passes through the center of the plate and the first and second plates.
It consists of a combination of first, second, and third cutters arranged on the back side of the plate, between the first plate and the second plate, and on the front side of the second plate, and the cutter is arranged between the first and second plates. The second cutter placed in the second plate has a single blade with a cutting edge formed only on the back side of the second plate, and is placed with a predetermined gap formed in the front side of the first plate. The present invention provides a chopper cutting device having such a configuration.

Effect With the above configuration, the raw material supplied into the hopper of the hopper is force-fed toward the first plate by the screw in the body, and at the position of the first plate, the raw material is fed into the hopper of the hopper. Rough cutting is performed by a first cutter placed on the side. Then, it passes through the through hole of the first plate and is pushed out between the first plate and the second plate. Here, the second cutter has a single edge, and the part without a cutting edge is placed on the front side of the first plate to face each other with a predetermined gap, so that the second cutter is coarsely cut from the first plate. The raw materials that come out are stirred and kneaded using the bladeless part of the second cutter to increase the degree of binding and prevent dryness. Then, the subsequent raw material is fed under pressure by the screw in the body, and the product is formed into a predetermined particle size and discharged from the second plate. The third cutter placed in front of the second plate cuts the grains of the product to a uniform length, and the cutting edge of the second cutter cuts the grains roughly cut by the first cutter. It cuts raw materials into small pieces.

Embodiment FIG. 1 shows an embodiment of a chopper cutting device according to the present invention, and the same constituent members as in FIGS. 2 and 3 are given the same reference numerals, and their explanation will be omitted.

In the drawing, 10 is a first plate disposed at the back inside the fuselage 1, 11 is inside the fuselage 1,
A second plate 12 is disposed on the front side at a predetermined distance from the first plate 10.
A first cutter 13 is approximately cross-shaped and is disposed on the back side of 0, and a second cutter 13 is approximately cross-shaped and is disposed between the first plate 10 and the second plate 11.
The cutter 14 indicates a third cutter having a substantially cross shape and disposed on the front side of the second plate 11.

The first and second plates 10, 11 are fixed in the body 1 by a key 15 as in the conventional device described above, and the first to third cutters 12, 13, 14 are It is locked to a rotating shaft 16 that passes through the first and second plates 10 and 11.

As shown in the figure, the first plate 10 has several relatively large-diameter through holes 17 formed at equal intervals, and the second plate 11 has relatively large-diameter through holes 17 formed at equal intervals, and the second plate 11 has relatively large-diameter through holes 17 formed at equal intervals. A large number of through holes 18 are bored.

The first cutter 12 has a substantially cross shape, and has a side facing the first plate 10, and
Cutting blades 12a, 12a, . . . that come into sliding contact with the first plate 10 are formed on the edge on the rotation direction side.

The second cutter 13 is disposed with a predetermined gap g between it and the first plate 10, and the second cutter 13 is located at the edge of the second plate 11 on the side facing the second plate 11 and on the rotation direction side. Cutting blade 1 in sliding contact with 11
3a, 13a... are formed.

The third cutter 14 has a second cutter on the edge facing the second plate 11 and on the rotation direction side.
Cutting edges 14a, 14a, . . . that come into sliding contact with the plate 11 are formed.

The operating procedure of the chopper equipped with the cutting device B having the above configuration will be explained below.

First, when a motor (not shown) is started and the screw is rotated in a predetermined direction via the gear box 3, the rotating shaft 16 connected to the screw also rotates, and the first to third cutters 12, 13, 14 also rotate to the plates 10, 11. Rotates while sliding in contact. When raw materials such as fish meat are fed into the hopper section 2 in this state, the raw materials are transferred to the cutting device B by the screw.
will be sent under pressure.

The raw material fed under pressure by the screw is first cut by the cutting blades 12a, 12a, .

A gap g is provided between the raw material passing through the through holes 17, 17, . , since no cutting blade is provided on the side of the second cutter 13 facing the first plate 10, the through holes 17, 1
No cutting is performed at the time of extrusion from the second cutter 13, and the second cutter 13 flows through the gap g and is kneaded while being forced toward the second plate 11.

The raw material pressure-fed toward the second plate 11 is transferred to the cutting blades 13a, 13a, . . . of the second cutter 13.
It is pushed into each through-hole 18, 18, . . . of the second plate 11 while being cut by.

By the way, the through hole 1 of the second plate 11
8, 18... are tapered holes as described above, so the above raw material is passed through the through holes 18, 1.
8,... as it passes through, it is compressed and hardened, and when it comes out from the through hole 18, the third cutter 14
are sequentially cut into predetermined lengths by the cutting blades 14a, 14a, . . . to produce granular products.

Since this granular product is kneaded by the second cutter 13 between the first plate 10 and the second plate 11, it is manufactured to have a uniform composition and has a high degree of bonding.

Therefore, if the apparatus of the present invention is used to produce granular feed for marine aquaculture as described above, it will not lose its shape even when dropped onto the sea surface, so it will not pollute the seawater and cause the feed to lose weight. No superior feed can be produced.

In addition, in the above explanation, each cutter 12, 13,
Although the planar shape of 14 is a substantially cross-shaped four-blade cutter, the device of the present invention is not limited to this, and may be a two-blade or three-blade cutter.

Furthermore, the cutter cutting device according to the present invention includes:
The present invention is not limited to granular feed for marine aquaculture as described above, but can be applied to any type of granular product that produces granular products.

Effects of the Invention According to the present invention, the raw material supplied into the hopper of the chopper is forced toward the first plate by the screw in the body, and at the position of the first plate, the raw material is fed into the hopper of the chopper. The first
Roughly cut with a cutter. Then, it passes through the through hole of the first plate and is pushed out between the first plate and the second plate. Here, the second cutter has a single edge, and the part without a cutting edge is placed on the front side of the first plate to face each other with a predetermined gap, so that the second cutter is coarsely cut from the first plate. The raw materials that come out are stirred and kneaded using the bladeless part of the second cutter to bond and increase the strength, thereby preventing dryness.
Then, the subsequent raw material is fed under pressure by the screw in the body, and the product is formed into a predetermined particle size and discharged from the second plate. The third cutter placed in front of the second plate cuts the grains of the product to a uniform length, and the cutting edge of the second cutter cuts the grains roughly cut by the first cutter. It cuts raw materials into small pieces.

In this way, the second cutter placed between the first plate and the second plate has not only the conventional chopping action but also the stirring and kneading action, so it can be used in a relatively simple manner similar to the conventional chopper. With this structure, it is possible to improve the degree of binding of granular products, and as feed for farmed fish, it is possible to reduce loss of weight due to decomposition of granules in water such as seawater, and to increase the feed administration effect, making it economical. This has the advantage of reducing seawater pollution and improving the growth of farmed fish.
