Abstract

The invention relates to the fishing industry, in particular to the mechanization of cutting processes for small and medium-sized fish, such as herring, saury, gerbil, capelin. The aim of the invention is to simplify maintenance and increase reliability. The flaps 1 and 3 are made in the form of grooves having a cross-sectional shape corresponding to the shape of the abdominal and dorsal surfaces of the fish; the flap 3 has an oblique slice at one end to which the socket 4 is attached. The lower flap 1 has guide flanges that restrict the movement of the holder to horizontal plane. 3 il.

Description

1

The invention relates to the fishing industry, in particular to the mechanization of cutting processes for small and medium sized fish, such as herring willow, saury, gerbil, capelin.

The aim of the invention is to simplify maintenance and increase reliability.

FIG. 1 shows the holder

general form; FIG. 2 is a view A of FIG. one; in fig. 3 - node 1nafig „2,

The design of the holder in the form of U-shaped and V-shaped valves, corresponding to the shape of the dorsal and ventral surfaces of the fish, provides a significant area of contact between the valves and the body of the fish, which at the time of compression of the valves reduces the trauma to the raw material. For fish of small breeds, with a significant change in the length of the fish, its cross-section varies only slightly, therefore this design of the holder allows, without changeover, to cut up raw materials with different sizes in a known range.

The presence of a mouth for receiving fish allows the fish to be fed into the cassette while the latter is continuously moving, which makes it possible to automate the process of unloading the fish into the fish processing machines, the flaps are opened at this moment.

Connecting elements made of elastic material, for example rubber, in the form of rings, provide closure of the holder's valves. The use of such elements allows you to quickly change the cutting machine to another raw material by replacing the rings with others, with the necessary elasticity, which fixes the fish in the holder.

The design of the holder allows you to move the fish in it in the longitudinal direction for submission to the working bodies of the machine.

The holder for transporting fish contains a flap 1, made in the vice of the U-shaped groove along

the shape of the dorsal surface of the fish with guide ribs 2, and the flap 3, made in the form of a V-shaped groove corresponding to the shape of the surface of the fish. Obliquely

a bell 4 for receiving fish is attached. The connecting rings 5 are made of elastic material and cover both

Sash 1 and 3, one above the other.

In the working state, the moving holder is loaded with fish through the receiving opening of the bell 4 in a predetermined position: head on, back down. After this, the holder is closed, and the fish contained therein is evenly compressed by flaps 1 and 3, having a cross-sectional shape corresponding to the dorsal and ventral surfaces of the fish, and held in position with elastic rings 5, the guide flanges 2 are removed the possibility of distortions in the mutual operation of the valves 1 and 3.

A rotor of a cutting machine (not shown) is assembled from the required number of holders mounted on the shaft for a given capacity. The lower flap of the holder 1 is fixed on the rotor shaft, the axis of rotation of the latter is perpendicular to the vertical longitudinal plane of symmetry of the holder. The upper flap 3 is connected to a cutting machine cam that opens the flaps by removing the upper flap 1 along the longitudinal vertical plane of symmetry of the holder. At the moment when the holder's flaps are open, the fish are loaded into the hollow of the holder. At the same time, the fish head is exposed beyond the end edges of the holder for further cutting. The closing of the valves and the fixation of the fish with a predetermined crimping force are carried out only with the help of elastic rings 5.

The rings are replaced manually without any disassembly of the machine.

The movement of the fish inside the holder in order to feed the tail fin under the knife for cutting is carried out with the flaps opened due to the forces of gravity.

The extraction of the viscera is carried out by known methods without the direct penetration of working tools into the abdominal cavity of the fish. Thus, for small-sized fish, for example, herring, saury, gerbil, capelin, vacuum suction methods, hydromygea, or a combination of these methods, high-quality abdominal cleansing is achieved when cutting into a carcass.
