Description

Put. four

The invention relates to processing equipment for fish processing and can be used in enterprises and vessels of the fishing industry fleet.

A device for ripping and stripping the abdominal cavity of fish is known, which includes a conveyor with cassettes, a knife mounted along the process and a device for stripping the viscera.

The known device has the following disadvantages knife and brush for cleaning the internals are located on the same shaft

When cutting fish of an enlarged size, the knife and brush will be inserted into the vertebral part of the fish, and the abdominal cavity in the region of the anus will not be cleaned. When cutting fish of smaller size OE, the cut of the abdomen of the fish and the stripping of the entrails is not performed, since the device does not move the knife shaft and the brush shaft along the horizontal and vertical planes, which reduces the quality of cutting fish of different sizes.

Closest to the invention is a fish cutting machine, comprising an operating transport unit with cassettes, a knife for cutting the abdomen of the fish and a brush for abdominal stripping.

The known machine does not eliminate the main disadvantages of the previous device. The quality of cutting in fish of various sizes remains low. When you try to install a knife for cutting a test, an economical cut of the test will decrease, because the machine does not have a translation of the brush shaft and the knife shaft in the horizontal and vertical planes. When processing fish of a large fraction, the springs arranged on the brush exert more pressure. Thus, the bristles will remove the fish from the bone and expose the bones; the cavity of the fish in the anal fin area will not be peeled off. When processing a smaller fraction of the fish, the force of the springs is not enough for the brush to remove the intestines and remove the black film.

In addition, the disadvantage is that the knife holder does not have a device for installing a knife with a different type of cutting fish, which reduces the technological capability

The aim of the invention is to improve the quality of cutting fish and economical cutting of mousse in fish of different sizes.

The goal is achieved by the fact that the device for cutting fish, which contains a transporting organ with cassettes for fish, is a blade knife for cutting the head.

mounted on individual shafts with the ability to move vertically depending on the size of the fish, holder with a knife for ripping the abdomen and brush

for cleaning the abdominal cavity, it is provided with shafts that are reinforced so that they can move in a horizontal plane, and the knife holder has a groove located along an arc of a circle in which an additional flat knife is mounted.

Fig.7 - holder with a groove and a flat knife.

The device consists of a conveyor 1 with

0 cassettes 2 for fish installed in the course of the process above the conveyor 1 of the frame 3 with the mounted shaft 4 and inclined to the shaft 4 fixed by the holder 5 with the knife b for cutting the test. The hanger 5 has a groove 7 in which an additional flat knife 8 is mounted. A adjustable stop bar 9 is installed above the knife b against the movement of the conveyor 1, ensuring the end of the cutting edge

The device has a frame 10 with another shaft 11 in which is mounted. A fixed shaft 11 is fixed by a brush 12 in the form of an auger with a pitch of the turn equal to the distance between the centers of the cassettes.

5 2 intended for stripping fish from the viscera. The frames 3 and 10 have a locking pin 13, inserted into the groove 14, on the stand 15, which provides for the translation of the shaft along a horizontal plane.

0 On the other hand, the frames have a clamp 16, connected by a screw 17 to a stand 18, for shifting the shaft in a vertical plane. To perform a soft abdominal cleaning of the fish with a brush 12 clamp.

5 16 is equipped with springs 19, and the frame 10 is a swivel 20. The shafts 4 and 11 have a mechanical drive 21 connected by a set-up clutch 22, mounted on a common shaft 23, which is connected on one side

0 to the gearmotor 24, and on the other to the gearbox 25, which provides the specified turns of the conveyor 1. The device is equipped with a disk knife 26 for cutting the head and a disk knife 27 for cutting the tail of the fish.

5 Both knives are connected with a motor with a motor 28. In order to perform a high-quality cut of the caudal fin in different-sized fish, a wheel 29 is brought to the cutting edge of the disk knife 27. The sprocket 31 mounted on the shaft 30, on the other hand, the sprocket 31 is mounted in the shaft 30 and connected In this way, the shaft 30 and the conveyor 1 are mounted on the foundation 32. For stable processing of fish, the conveyor 1 has a run-in groove 33 of cassette rollers 34. In addition, along the conveyor 1 on the foundation 32 a road 35 is installed, including a cassette strip 36 for pressing the fish ohm ribbon spring 37. The device comprises a cylindrical brush 38 with a drive 39 for dozachistki from the surface of the fish neotorvannoy kishechki, cutting the split abdomen.

The device works as follows.

The gearmotor 24 is turned on, which, through the gearbox 25, produces the design turns of the conveyor 1. At the same time, the shaft 4 with the knife 6 and the shaft 11 with the brush 12 are driven into motion by the common shaft 23 and the mechanical drive 21. The disk knife is activated. 26 for cutting off the head and a circular knife 27 for cutting off the caudal fin. In the cassette 2 lay the fish belly up. Prior to the approach of the cassette 2 with fish to the cutting, the ribbon spring 37 is inserted into the engagement of the road 35. During this period, the cassette strip 36 presses the fish carcass, after which the disk knife 26 cuts off the head and the disk knife 27 cuts off the tail fin. For a good tail fin cut, wheel 29 produces a steady grip on the tail of the fish.

Along the line of movement of the cassettes, the fish will come to the inclined knife 6 fixed on the shaft 4, where the speed of movement of the holder 5 is equal to that of the cassettes 2, and the speed of movement of the cutting edge of the knife 6 is ahead of the speeds of movement of the cassettes 2. . At the end of the cut, the stop bar 9 rests in the basket, allowing the blade of the knife 6 to pass between the plate 9 and the cassette 2 to cut the skin. During the rotation period of the knife 6 along the trajectory, the next carcass of the fish is advanced, the blade of the knife 6 again cuts into the carcass, the cutting process is repeated. During the transition to the cutting operation of the small fish in the groove 7, the flat knife 8 is installed and secured. Rotate the screw 17 to adjust the cutting depth with the knife 8. If the flat knife 8 and the knife 6 cut behind the anal fin, for this

finger 13, and then the frame 3 with the shaft 4 and the knife is moved on a horizontal plane in the direction of the head of the fish.

Along the line of movement of the fish cassettes, the brush 12 enters into the abdominal cavity on the side of the head with a screw with a pitch of the turn equal to the distance between the centers of the cassettes 2. In this case, the speed of movement of the edge of the brush 12 is equal to the speed of movement of the cassettes 2. removes black film, cleans blood clots and black kidney. To cut up the larger fraction of fish on the frame 10, the fixing pin 13 is tightened. The shaft 11 with the brush 12 is moved in the horizontal plane towards the tail fin of the fish, the fixing pin 13 is pressed. Rotate the screw 17 to reach the pressure of the brush 12 on the abdominal cavity of the fish. To cut fish of a smaller fraction, the movement of the shaft 11 of the brush 12 is carried out on a horizontal plane in the direction of the fish head. Thereafter, the movement is carried out in a vertical plane by rotating the screw 17, which improves the quality of the cutting.

The technical and economic efficiency of the invention consists in improving the quality of cutting fish of various sizes by moving the knife into a horizontal and vertical planes to cut the fish’s mash and reconfigure the brush into the cavity to clean the fish, which prevents its repeated processing; in increasing efficiency for an economical cut of the test; in expanding the technological capabilities of cutting fish with an additional flat knife.
