SU107505A1 - Device for cutting fish, mostly bull - Google Patents

Description

The subject of the invention is: a device for cutting fish, preferably a bull, using an endless feed chain with fish hooks, operating disc knives and a guillotine-type knife for cutting off the tail fin.

The proposed device, in comparison with the known similar devices, improves the quality of cutting and increases productivity. This is achieved by using two augers rotating one against the other, one of which is clamping for the supplied fish and the other one for working.

The working auger is made in the form of a hollow shaft with holes for the shower and is provided with a spiral knife sequentially arranged along a helical surface for ripping the abdomen, an abdominal expander and a screw brush for cleaning the abdomen from the insides.

FIG. 1 is a schematic side view of the device; in fig. 2 - its top view; in FIG. 3-section on LL in FIG. one; in fig. 4 - view of the working screw.

An endless chain / hooked mi 2 for fish suspension, mainly a bull, for the lower jaw feeds the fish for fixing and cutting for augers 3 and 4 rotating towards one another; screw 3 is presser and screw 4 is working.

The working screw 4 is made in the form of a hollow shaft D) with a shower holes 6 for water. A spiral knife 7 for ripping the abdomen of the fish, an expander 8 of the abdomen and screw brushes 9 for cleaning the abdomen are successively placed on the shaft 5 along a helical line.

For cutting off the fish head, the device is equipped with operating disc knives 10, and for cutting off the caudal fin with a knife 11 of the guillotine type.

The fish for cutting is manually hung on a hook 2 of infinite value /, which brings it under the guillotine knife //, which cuts off the tail fin.

With further advancement of the chain 2, the fish is fixed by screws 3 and 4 n processed by working tools placed on the surface of the hollow shaft 5 of the screw 4, its abdomen is ripped by a spiral knife 7, then the abdominal dilator 8 enters the open peritoneum, and after the last screw brushes 9 for cleaning fish from entrails. At the same time, the fish is treated with water coming from the openings 6 of the hollow shaft 5.

After that, the fish are clamped by screws exposed to operating disk knives / (cutting the head. At the same time, the fish carcass enters the receiving hopper 7.2 and the water flows along the chute out of the machine. the drawing is not shown) is reset to the receiver / 5.

Subject invention

A device for cutting fish, mainly a bull, using an endless feed chain with hooks for suspension, operating disk knives and for cutting off the tail fin of a guillotine-type knife, so that, in order to increase quality of cutting and increase in labor productivity, it uses two augers rotating towards each other, one of which is clamping for the supplied fish, and the other - working, with helical rows along the helical surface for ripping the abdomen a, expander abdomen helical brush for cleaning of the abdominal viscera and hollow shaft and provided with a water dushiruyuschimi apertures.
