Description

This invention relates to fish processing equipment and is intended for removal of the head, ripping and stripping the abdominal cavity of a fish.

Known machines for cutting fish, for example, hake, hake, sea crucian carp, consisting of an operational chain conveyor with transversely fixed cassettes for laying fish belly up and consistently along the conveyor along the process of a circular knife for incision of the head from the side of the abdomen, two profile slats installed one above the other with the formation of a gap for the fish to enter into it with a head notch and fixing it in the process of cutting, an abdominal cavity ripping and stripping mechanism Containing fortified on a common shaft crescent knife for opening the abdomen, rasplastyvatel and brushes disposed under the lower run of the conveyor means for the intestine tearing, disc knives for cutting the head and the supporting guideway.

In order to improve the quality of cutting and prevent cutting of the spine, the proposed machine is equipped with a spring-loaded figured emphasis installed under the circular knife for incision of the head and a distance equal to the height of the backrest.

fish of minimal size, and to limit the depth of incision of the head, the entrance end of the upper profile bar is fixed directly above the spring-loaded stop. The abraded and abdominal stripping mechanism and the circular knife for cutting the head are located under the lower branch of the conveyor. Each cassette of the operating conveyor should be made with a spring-loaded side plate to secure the fish from lateral displacement.

FIG. 1 schematically shows the proposed machine; in fig. 2 - notch unit

heads, side view in FIG. 3 - the same, front view; in fig. 4 - the mechanism for ripping up and stripping the abdominal cavity.

The machine consists of an operational chain conveyor 1 with transversely fortified

cassettes 2, successively arranged along the technological process of the disk knife 3 for incision of fish heads from the side of the abdomen, spring-loaded figure stop 4, two profile bars 5 and 6, installed one above the other to form a gap for entering the fish with a head notch and fixing the cutting process , the mechanism for ripping up and stripping the abdominal cavity, consisting of the spreader 8 and the brushes 9 fixed on the tarp, and the brushes 9 placed under the lower branch of the conveyor belt in the form of grooved rollers .10, // cutting disc cutter to cut the head and the supporting guideway 12.

The entrance of the profile web 6 serves to prevent cutting of the spinal column and is set on the side of the knife in such a way that the knife goes beyond its limits by 1-2 mm. The spring figured support 4 serves to ensure reliable pressing of fish having different back height with their spine all the way into profile bar 6. It is located under disc knife 3 at a distance equal to the height of the back of the smallest of treated fish.

Thus, if a fish with a high back falls on the groove, then it, resting its spine on the bar 6, pushes the spring stop 4 down. At the same time, the knife goes deeper into the spine no more than 1-2 mm.

In each cassette of the operating conveyor / there is a spring loaded lateral plate 13 for fixing the fish from the lateral displacement.

Scale works as follows.

The fish are manually placed in the cassette 2 conveyor / black up, the reference gill flares on the ends of the cassettes. According to the conveyor, it approaches the disk knife 3, where it is slightly raised by the support 4 towards the knife. Since the cutting force of the bone is greater than the muscular tissue, and the knife does not protrude more than 2 mm relative to the bar 6, as soon as the knife reaches the spine, the latter rests on the bar 6. In this case, the knife cannot cut the spine. Depending on the height of the back, the spring stop 4 is deflected. This stop presses with such force that the head of the fish is lifted towards the knife and its tail is depressed by pressing the bar 6 onto the spine. The limit of the stop is limited by the lock. Passing the knife 3, a fish with a notch at the head enters the gap between the slats 5 and & and is kept by them when ripping up the abdomen with a knife 7 and spreader 8, as well as during stripping

the brush cavity 9. The remains of the saucer are torn off by corrugated rollers, after which the head is removed with a knife. This operation is carried out with an economical figure cut, since before this, with the bars 5 and 6, the head is bent in the direction of the back of the fish. The guide 12 holds the tail of the fish.

Subject invention

1.Machine for cutting fish, such as hake, hake, sea crucian carp, consisting of an operational chain conveyor with transversely reinforced cassettes for laying fish belly up and in series along the conveyor along the process of a circular knife for incision of the head from the side

abdomen, two profile strips, installed one above the other with the formation of a gap for the fish to enter into it with a head notch and fix it in the process of cutting, the mechanism of opening and stripping the abdominal

cavities containing a crescent-shaped knife mounted on a common shaft to open a noose, a sweetener and a brush placed under the lower branch of the conveyor of a device for tearing off a tweezer or a disk knife

for cutting off the head and supporting guide, characterized in that, in order to increase the quality of cutting and prevent cutting of the spine when incising the head, the machine is equipped with a spring-loaded figured support installed under the circular knife for cutting the head at a distance of the minimum fish size, and to limit the incision of the head,

The input end of the upper profile bar is fastened directly above the spring-loaded stop, with this. The mechanism for ripping and stripping the chasing cavity and the disk knife for cutting the head are located under the lower branch of the conveyor belt.

2. Machine no. 1, different from those.m, that each cassette of the operating conveyor is provided with a spring-loaded side plate for fixing the fish from lateral displacement.
