Description

This invention relates to the fishing industry.

A known fish cutting machine is contained, and an operating conveyor with fish trays and two head cutters are positioned along the conveyor one above the other to form a gap for the food duct and two discs that turn in the opposite direction to remove the head with the insides 1 .

The disadvantage of this machine is that it does not provide for the cutting of small fish, since it is impossible to adjust the knives, cutting the headings in fish like a hamsa, sprat, so as not to affect the insides.

The closest to the invention in technical sushi is a device for cutting fish, containing an operating conveyor with fish cassettes, a knife for incising the head from the back, a retaining bar, a pulley - a disc with an elastic rim for placing fish heads and a rotor lifting and lowering spring clips 2.

A disadvantage of the known device is that it does not provide high quality cutting of small fish such as hamsa and sprat, and because of the need to place the fish in the cassette backwards, it requires the introduction of additional elements — a rotor with clamps to fix it.

The purpose of the invention is to improve the quality of cutting fish by improving the reliability of fixing it.

The goal is achieved by the fact that in a small fish cutting machine, containing an operating conveyor with fish cassettes, a disc with an elastic rim, synchronous movement with it, knives for notching the fish head, a peremetdny mechanism for fish in a cassette for mounting it to an economical cut, including a hydro-nozzle, a disk made with a hub on which a guide has the shape of a ring, and fixing plates are installed on the guide with the possibility of swinging movement to prevent lateral displacement g fishing, knives for incising the head part are also fixed on the guide with the possibility of rocking motion, there is an emphasis above the disk, made in the form of a grid for skipping the hydrojet and creating a pair of adjacent fixing plates of the cell for the fish, and above the operating conveyor is mounted on the axis c the possibility of free rotation of the clamping disc with a notch to keep the fish from longitudinal movement. In addition, the knives have triangular teeth.

At the same time, in order to reduce the adhesion forces of the fish with the cassette, a plate is installed above the hydropod to interact with the tail of the fish.

FIG. 1 shows a schematic of a small fish cutting machine; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. 2; in fig. 4 shows a section B-B in FIG. 2

The machine for cutting small fish contains an operating conveyor with cassettes 1, a hydro nozzle 2, a plate 3, a disk 4 with a notch along the rim, knives 5 for removing heads and entrails, fixing plates 6, copiers 7 and 8, an emphasis 9, table 10,

elastic ring 11, guide 12, pressure flange 13 with clamps 14, scraper 15.

The side walls of the cassettes 1 in the area where the fish are located are cut off to ensure the operation of the disk 4, which holds the fish in the cassette. Hydro nozzle 2 is designed to push the fish. At the exit, the nozzle is flattened and is a horizontal slit, due to which the time of action of the water jet on the fish moved by the operating conveyor is increased. Plates:,: i is installed above the gyroplane 2 in such a way that the tail part of the fish, when moved by the conveyor, rises above the cassette and enters the plate, thus disrupting the adhesion of the fish to the cassette 1, which prevents the fish from moving with a waterjet. The disk 4 is mounted on a horizontal axis, it rotates freely upon contact with the fish being moved in the cassettes 1 and keeps it from moving

along the cassette when removing the head and. viscera.

Knives 5 are mounted on guide 12, dispersed in table hub 10 and fixed by clamping flanges 13.

with lock; : n 14. Knives 5, contact with copiers 7 and 8, make a swinging movement around guide 12 and rotational movement together with table 10 synchronously with the cassettes 1 of the operating conveyor. Knife teeth 5

have a triangular shape.

The locking plates 6 are designed to prevent lateral displacement of the fish heads at the time it is delivered by the hydro jet to the fixing cell under the knife 5. The plates 6 are mounted on the guide 12 and, due to the action of copiers 7 and 8, rotate around the guide 12 and rotate together with the table 10. Copiers 7 and 8 are fixed on the frame

machines and reported swinging movement of the knives 5 and the locking plates 6.

Emphasis 9 is fixed on the frame and is designed to install fish on an economical

res. The working part of the stop 9, into which the fish is pushing, stops the fish at a given point and does not prevent it from moving along with the fixing cell formed by the stop 9 and the plates 6.

Guides 12, groups of knives 5, groups of fixing plates 6 and elastic, for example rubber, ring 11 are placed on the table 10, preventing the blunt edges of the triangular teeth of the knives 5 from blunting the fish.

The guide 12 is installed in the ring-and-slot groove of the table hub 10. The retainers 14 of the pressure flange 13 are used to fasten the guide 12 into the groove of the table hub 10. The scraper 15 is fixed on the frame and is designed to remove the heads and entrails from the machine.

Maschina works as follows.

Fish, orientiron.shnl head toward the device d.-. KviKn, with the tail fin removed (or unremoved) by any of the known methods, is placed in the cassette 1 of the operating conveyor so that its tail portion protrudes beyond the edge of the cassette. This is because the tail part of the fish is lifted in front of the hydraulic nozzle 2 and enters the plate 3, detached from the harness of the cassette 1, and the fish’s adhesion to the cassette is disturbed.

Hydraulically retracted, the fish hits the head in the fixing cell formed by the plates 6 and the stop 9. The plates 6 are under the influence of the copiers 7 and 8 at the point of pushing the fish

in the lowest position. The knife 5 at the time of pushing the fish into the fixing cell is in its extreme upper position.

During the rotation of the table 10, the knife 5 under the influence of the copier 7 makes a movement down and cuts the fish carcass in the head part. Upon further movement of the knife 5 along with the table 10, the head of the fish along with the internals is separated from the carcass. The carcass is at that time held in the cassette G by the disk 4. Disk 4, slightly deforming the fish along the line of contact with it, presses the carcass to the bottom of the cassette, wedges it and thereby keeps it in the cassette during the period of separation of the head and viscera from the duck.

A carcass of shredded fish is sent for further processing. In the waste removal zone of the machine, the knife 5 and the plates 6 are removed by the copier 8 to the highest position and create conditions for dropping the waste from the table 10 with a fixed scraper 15.

The annual economic effect from the introduction of one machine while cutting fish 1 1 type of hamsa and sprat will be 11.9 thousand rubles.
