FIG. 1 shows a cross-section of the machine; in fig. 2 - the same, section A-A of FIG. one; in fig. 3-part cross section of the drum; in fig. 4 - sections BB and B-B of FIG. 3; in fig. 5 - knot for cutting off the caudal fin with a cut Г - Г; in fig. 6 shows sections D-D and E-E of FIG. five.

The machine consists of a revolving hollow surgical drum 1 assembled from cassette disks 2, a device for placing fish on the head cut, a vibrator 3 for cutting the head, a device for removing intestines and a node for cutting tail fin.

The cassette disk 2 can have any number of cassettes 4 directed along the radius to the axis of rotation of the operating drum. The pitch t of the cassette 4 along the generatrix of the inner diameter of the drum 1 is equal to the height of the fish being processed, taken at its largest cross section, which achieves the greatest density of the cassettes in disc 2.

A device for placing fish on the head cut is installed inside the operating drum 1 and is made in the form of a rotary drum 5 with cells, whose pitch in the outer diameter is equal to the pitch of the cassettes 4 of the operating drum 1 in its internal diameter. The cells are shaped like a fish's head and are a continuation of the cassettes 4 during the loading of the fish.

Vibrating cutter 3 is plate-shaped and mounted on brackets 6 on rod 7 in bearings 8. Vibrating cutter is connected to electric motor 9 through an eccentric clutch (not shown in the drawings).

Vibrating cutter 3 is made in an arc, the conceptual axis of rotation of the drum, and is installed along its length so that the heads are cut at the same time for the entire batch of 4 fish loaded into cassettes.

The internals removal device consists of an outer pipe 10, an inner pipe 11 and a seal 12 between the pipes to prevent air from leaking out of the atmosphere. The pipe 10 has annular grooves with holes 13, the number

which corresponds to the number of cassette disks in the drum, and in diameter these holes are arranged with a pin equal to that of the cassettes in the inner diameter of the drum 1. The tube 10 through the pinions 14, 15 is kinematically connected with the operating drum. The inner pipe 11 is fixedly mounted on the brackets 6. On the one hand it is closed, on the other it is open and connected to the hose through which the internals are sucked.

The inner tube 11 has one row of holes 16, and these holes are larger in diameter than the holes in the outer tube 10, in order to ensure a longer suction cycle. The holes on the pipe 11 are located along the axis of the radius of the drum 1 and are directed in the direction of the cassettes 4. The suction of the internals occurs only in the period when the holes on the pipes 10 and 11 are aligned.

On the outer side of the operating drum 1, a loading device is installed, which consists of feeding needles 17 fixedly mounted on a carrier bar 18. The latter is mounted on traction chains 19 with a drive sprocket 20. The loading device has trays 21, which are a connecting link between orienting device (not shown in the drawings) and fish processing machine. In the lower part, the trays 21 have a slot for the passage of the needle 17. The loading device and the operating drum are synchronously connected to each other.

The node for cutting the tail fins consists of stationary guides 22, which have a cone-shaped cross-section for better entry of fish into them with the tail forward when it leaves the cassettes 4. To the guides 22 from the outside, a bar 23 is not fixedly mounted caudal fins. To the bar 23, the bearings 24 mounted on the shaft 25 are loaded with spring-loaded knives 26, which are fixedly attached to the rod 27. The spring-loaded blades 26 are constantly and pressed against the bar 23, which eliminates the gap between the knife 26 and the bar 23 and improves the conditions cutting the tail fin, compensates for the wear of the knives, which in this case are self-sharpening.

The knife 26 for cutting off the caudal fin is made in the form of an isosceles trapezium with curved lateral cutting edges and becomes a smaller base towards the tail fin.

To knock out fish from the cassettes 4 into the guides 22, nozzles 28 are installed, feeding water jets to each cassette 4. At the end of the guides 22 on the inner side of the drum 1 there is a mechanism for knocking the fish out, which consists of a pipe 29 and sprockets with prominent conical

using fingers 30 to push the fish out of the drum cassette 1 and roll it along its inner diameter. The tube 29 has a number of holes equal to the number of cassette disks. In the tapered fingers 30, the asterisks are also made through holes for the pulsed water supply to the cassette 4.

The pallet 31 serves to remove the cut heads from the machine.

The machine works in the following way.

The fish from the orientator (not shown) enters the loading device, pgl 17 passes the tray 21, at the end of it comes off the needles 17 due to inertia and goes into the cassette 4 of the operating drum 1 until it stops at the fish setting device heads. The cell of drum 5, owner, and with the continuation of cassette 4, tightly closes it at the moment of cutting the head.

The loading device feeds the fish in batches according to the number of cassette disks 2 into each cassette 4 continuously vras, the operating drum 1. The fish loaded into the cassette 4 and into the cell of the drum 5 is fed by the drum 1 to the vibrator 3. After the fish touches the blade of the vibro-blade 3, the fish remains on its outer surface until the head is completely cut, the drum 5 at this time seems to roll around the inner diameter of the drum 1, from the moment the cut begins, the head begins to leave the cell of the drum 5, which further provides free lunge her from the cells.

The remaining carcass 4 in the cassette is fed by the drum 1 to a device for removing intestines, by means of which the latter are sucked.

The suction of the viscera begins from the beginning to the last moment, when the holes on the pipes 10 and 11 mix together. The annular grooves on the outer pipe 10, as well as larger holes on the inner pipe 11, increase the duration of the suction cycle. When the combination of holes on pipes 10 and 11 is completed, the suction of the internals stops, at this moment an increase in the depth of vacuum occurs, which saves its consumption, and consequently, the performance of the vacuum pump is less. After the beginning of the next alignment of the holes in the pipes 10 and 11, the process is repeated. The suction of the entrails of each subsequent batch of fish occurs through a new series of holes in the outer tube 10, which rotate synchronously with the cassettes 4. In case of clogging of the holes in the outer tube 10, they are self-cleaning using the inner tube 11, through which the tube 10 runs around its holes mi

Headless and gutted fish carcass continues its way in cassette 4 to nozzle 28, the water jet of which knocks out

the whole batch of fish in the guides 22 under the cut of the tail fin.

Cutting off the caudal fin is carried out using an economical cut due to the slit formed by the guides 22. Only a part of the caudal fin with a certain thickness of the tail section passes into this slit. Spring-loaded knives 26, along with shchtanga 27, reciprocate from the cam mechanism and cut off the tail fins of the batch to process the fish.

The processed fish continues its way in the cassette 4 of the reel 1, the slippery cut-off tail part along the guides 22. The mechanism for turning the fish around the inner diameter of the drum 1 and its protruding taper fingers 30 sprockets into each cassette 4 and simultaneously pushes the fish out of the constriction The cassette 4, thus creating favorable conditions for a jet of water that is less sprayed, requires less pressure and beats concentratedly in the center of the cassette, forming a continuous water column over the entire cross section of the cassette. As a result, all fish batches are simultaneously pushed out and fish are unloaded from the machine in even rows, which

It is necessary for further technological process, for example, smoking, for solving the problem of mechanized loading of cut fish on the canvas of the transporting organ of the electro-smoke plant.

In order to save on water consumption, the mechanism for knocking out fish delivers a stream of water to the cassette, periodically with short pulses at the time when the hole on the tube 29 is aligned with the through hole on the conical pin 30 of the sprocket.

The proposed machine is simple and compact in comparison with the known machines designed to perform

data operations, high-performance and reliable in operation.

The theoretical capacity is 1200 fish / min. At the same time the machine provides high-quality cutting

fish, which is achieved due to the small peripheral speeds of the surgical drum.

As a result of the use of the invention, the expected economic effect will amount to 33 thousand rubles per car.
