SU1204165A1 - Device for orientating fish - Google Patents

Description

The invention relates to fish industry and can be used in loading devices for fish processing machines and in devices for loading fish into tar where orientation of the fish with one tail is required.

The aim of the invention is to improve the orientation accuracy of fish in a wide size range by eliminating the possibility of wedging its tail section.

The invention provides a clearer piece-by-piece separation of fish carcasses.

Fig, 1 shows a device, a general view, a section; in fig. 2 - the same plan.

The device for orienting fish contains a conical table 1 mounted on axis 2, a stationary feed cylinder 3 with a guide bar A, concentrically arranged annular flange 5 mounted above table 1 with a gap in the form of a slit 6, a visor 7 fixed on the annular board 5 in the fish feed zone, an annular sector 8 with a set of teeth 9, mounted outside the annular flange 5, trays 10 and 11, respectively, loading and unloading fish, gearmotor 12, pulleys 13 and 14, frame 15.

The device works as follows.

Fish in the loading tray 10 in bulk without orientation, 4-5 pcs.

at the same time it is applied to the rotating conic table 1 and under the action of centrifugal force it is pressed against the cylinder 3 and further along the guide bar 4 it is fed almost one by one to the conical visor 7 fixed on the annular side 5.

If the carcass of the fish enters under the visor 7 forward with a cut, then its reversal will not occur due to the fact that the center of gravity is located closer to the heading cut. In this case, the seizure will not occur either, since crimping the cylindrical part of the fish's head cut, with the surface of the visor 7 located at an angle of 30-50 to the horizontal, and the surface of the table 1 will be minimal.

If the carcass of the fish enters under the visor 7 by the caudal fin forward, then under the action of centrifugal force and due to the visor 7, the caudal fin will clearly enter the crevice, the fish’s tail will be pressed into the tooth 9 and it will turn forward with a headcut. In this case, the jamming of the fish does not occur, since the tail part cannot go far into the slot due to obstacles in the form of an annular sector 8 with a set of teeth 9. The rotation of the disk 1 is carried out from the gearmotor 12 by means of the V-belt drive and the pulleys 13 and 14.
