The invention relates to the fish processing industry of the fishing industry and can be used for cutting fish on fishing vessels and coastal fish processing enterprises.

The purpose of the invention is to improve the quality of cutting by ensuring reliable fixation of fish during processing.

FIG. 1 schematically shows a device for cutting fish, front view; in fig. 2 - section A — A in FIG. one; in fig. 3 - a device for mounting fish on an economical head cut, front view; in FIG. 4 a section BB in FIG. 3; in fig. 5 shows a section B-B in FIG. 3; in fig. 6 - a device for feeding fish for an operation to cut off the head, front view; in fig. 7 - section G-Y in FIG. 6; in fig. 8 - an operating drum with nos-dd teli, front view.

The device for cutting fish (figure 1) includes a feeding tray 1 for fish, a device 2 for placing fish on an economical head cut, including a device 3 for feeding fish for the operation of the head sections, as well as an operating drum 4 with trays 5 whose circumference is In the course of the technological process, there are placed a disk knife 6 for cutting the head, a mechanism 7 for fixing tail fins, a mechanism 8 for removing internals, a disk knife 9 for cutting the tail fins.

Above the drum surface concentric with its circumference is mounted guide casing 10.

Tray 1 for feeding fish includes spring-loaded side flaps 11, as well as spring-loaded stop 12.

The device 2 (Fig.3,4,5) to install fish on an economical head cut contains a rotor 13, which is formed by a pair of disks 14, rigidly mounted on the shaft 15.

Between the disks 14 parallel to the shaft '15 with the possibility of rotation fortified axis 16, on which in the rotary axles 17 is diametrically opposite

two pairs of clamps 18 are fastened. Moreover, clamps 18 are strengthened with the possibility of angular movement relative to each other by means of copiers 19, and also with the possibility of rotation relative to the axes 16 on which they are fixed.

On the surface of the rotor 13 in front of each pair of clamps reinforced, comb 20 with curved top teeth for pre-opening the gill covers. Above the rotor 13 concentric with its circumference is mounted, a guide cover 21.

The device 3 for feeding fish to the operation of cutting off the head (Fig. 6, 7) contains a rotor 22, rigidly fixed on the shaft 23, on which two pairs of grippers 24 are fixed on diametrically opposite sides.

The grippers 24 make an angular movement towards one another under the action of the copier 25.

solo mounted on the short arm of the L-shaped lever 27, spring loaded 28, and mounted on a horizontal axis 29 with the possibility of $ reciprocating swinging motion using a roller 30 rigidly connected to the axis 29 and kinematically interconnected with a cam 31.

The mechanism 7 (Fig. 2) of fixation of the needles of the fins includes a trap 32 and a clamp 33 fixed on the surface of the drum 4 behind each tray 5.

Each trap 32 is made in the form of two guide plates 34 and 35, 15 fortified with the formation of a curved converging groove, one of the plates 34 being fixed motionless, and the second 35th being able to move along the generator drum for adjusting the groove width.

The latch 33 is mounted opposite the outlet of each slot and is made in the form of a pack of trapezoidal plates, fortified with the ability to move along the surface of the drum 4 in order to adjust the position of the latch 33 depending on the size of the fish.

The mechanism 8 removal of the viscera 39 is made in the form of a circular knife 36 for ripping up the abdomen with ribs 37 radially reinforced along its circumference, rigidly fixed on the shaft 38. The disk knife 9 for cutting off the tail fins is fixed on the shaft 38.

The mechanism 8 includes a milling cutter 39 for abdominal cleaning, which is fixed on the shaft 40, and also a spreading device 41. The latter is made in the cross section of the i-shaped form for embracing the cutting edge of the knife '36 and with a toothed section 42 for cleaning the blood kidney.

Above the drum 4 concentric with its circumference in the area between the disk knife 6 for cutting the head and the knife 36 for ripping the abdomen is mounted a guide cover 10. It has a variable cross-section of a trapezoidal shape, tapering in the direction of movement of the fish.

The device can be either single-handed or multi-handed.

The device works as follows.

A fish head oriented to the front enters tray 1, while with its body it expands the spring-loaded side flaps 11 and abuts 38 ⁶

snout in the spring-loaded stop 12.

When the rotor 13 rotates, one of the combs 20, coming into contact with the fish, opens the gill covers with its teeth. Following the comb 20 in the open state, a pair of clamps 18 is moved. They grip the fish in tray 1 from the side of the abdomen.

At this moment with the help of copiers 19 clamps are closed on the body of the fish. Moving in the direction of her head, clips 18 go under the gill covers. Then, overcoming the effort, they deflect the spring-loaded stop 12 and remove the fish from tray 1, the side flaps 11 of which, tracing the sides of the fish, prevent the spontaneous movement of the next fish.

The fish removed from tray 1 moves along an arc of a circle with the help of clamps 18, which grab it by the gill covers, while keeping the fish position using the guide casing 21. Next, the fish enters the device 3, which feeds it to the operation of cutting the head. The shaft 23 of this device rotates the rotor 22, the jaw grips 24 of which open when copier 25 acts on them. When the trajectory of the gripper 24 and the head of the fish transported by the clips 18 coincides, the gripper 24 pinches the fish's head and feeds it to the knife 6 to cut the head!

At the same moment under the action of the copiers 19, the clamps 18 are rotated about the axis 16, pushing towards the bottom of the rotor 13 and freeing the fish.

Since the clamps 18 with sufficient accuracy fix the fish at the end of the gill covers, and the relative position of the clamps 18, grips 24 and the knife 6 can be adjusted, this mechanism allows you to remove the fish's head with maximum savings in the food portion.

When the disc knife 6 begins to cut off the fish’s head held by the catch 24, the lever 27 under the influence of the roller 30 interconnected with the copier 31, together with the tray 5 begins to rise, holding the carcass. As the head is separated from its head, the lever 27 smoothly lowers and by the time the head is completely separated, the tray 5 is lowered to the lower position. In this case, the carcass is located in his belly

up or with a slope. In the next moment, the lever 27 with tray 5 begins to rise and inserts the carcass under the guide casing 10. Due to the shape of its cross section, which tapers in the direction of the fish, the carcass when moving tray 5 around the circumference takes up the belly up. At the same time, the stroke of the lever 27 is designed so that when the tray 5 moves along the casing 10, the minimum of the processed fraction fish is pressed against it (the difference in the size of the fish is compensated by the spring 28).

As the cross-section of the guide casing 10 narrows between it and the fish, friction forces arise that shift the carcass in tray 5 in the direction opposite to the direction of movement until the tail is wedged in the trap 32. Due to the curved shape of the groove in the trap 32, the tail gradually bends, installed at an angle of 90 ° to the diametral plane of the fish and wedged in the lock 33, which serves as a stop for it.

Upon further rotation of the drum 4, the fish fixed in tray 5 with the help of trap 32 comes out from under the casing 10 and is fed to the knife 9, which removes the tail fin, and to the knife 36, which is fortified coaxially with it, to rip the abdomen. After that, the spreader 41 enters the abdominal cavity. As it covers the cutting edge of the knife 36, the possibility of damage to the spinal bone is prevented. When this edge 37 of the knife 39 is removed from the abdominal cavity of the main bundle of the viscera.

Further along, the spreader 41 pushes the side walls of the abdominal cavity of the fish somewhat and with its toothed section cleans the blood kidney. From the spreader 41, the fish in the abdominal cavity passes to the milling cutter 39, which produces the final abdominal cleaning from the remnants of the viscera, the blood kidney and the black film.
