Description

FIELD OF THE INVENTION The invention relates to the fishing industry, namely to fish processing equipment. According to the main auth. No. 490455, a device for removing scutes from a fish is known, which includes a conveyor with fish pushers, a centering device made from podprezzinnyh valves and freely rotating profile rollers, paired cutting tools, which are bowl-shaped. figurative knives, enclosed in KOSCJTXH, on which the profile guides and the fish drainage tray are installed in front of the cutting edges. A disadvantage of the known device is that it does not completely provide an economical cutting of the scutes of a fish, as a result of which the quality of processing of the fish does not always meet the established standards. Occurs (mainly in the middle part of the fish) nedorog strips with bugs, where the crowd of bugs decreases and the fish leaves the device with a string with bugs hanging on the knife. There is a need for manual modification to remove strips. With bugs. The described drawback arises from the fact that the profile guides are installed in front of the cutting edges of the knives with a gap, i.e. with an insufficiently pronounced cutting site to prevent displacement of cut off scutes from the force of knives down. In the process of removing scutes, when their dimensions in cross section decrease to the thickness of the skin, they are knocked into the gap with a blade and profile bar. and then the carcass of fish with under-cutting is pushed out of the device. The purpose of the invention is to provide an economical cutting of the scutes. The goal is achieved by the fact that the device for removing the scutes of a fish is provided with additional trays attached to directing and positioned inside the cups of the shaped knives so that the edges of the trays adjoin the inner parts of the blades of the knives, while the additional trays are made of a material softer than the cutting edges of the knives and mounted with the possibility of intersection of the cutting edges. Fig. 1 shows a device for removing scutes in a fish in Fig. 2, section A-A in Fig. 3 in Fig. 3 is a section B-B in Fig. 1. A device for removing scutes in a fish consists of bowl-shaped knives 1 with a cutting edge 2, covers 3 knives, profile guides 4 with shanks 5, protects of fish from contacting the blades during processing, the flange used for fixing the strips, additional trays 7, crepe schihs flanges 8, tray for removing fish and the conveyor with pushers (not shown). The profile guides.4 are shaped in cross section, analogous to the shape of the scissors, and fixed by means of fixing elements 9 and 10 on the covers 3 before the cutting edges 2 of the knives 1. The additional tray 7 has the shape similar to the shape of the profile guides 4, is made as their continuation and directed inside the cup-shaped knives, while the edges 11 of the trays 7 fit snugly (lapped) to the inner surface 12 of the cutting edges 2 of the knives 1. The length of the trays 7 (overlap area q) is slightly longer than the value of the cut 2 during operation of the knives. To fit the edges 11 and the trays 7 tightly to the inner surfaces 12 cutting edges 2 knives 1, the trays are made of a material less solid than the material of the cutting edges of the knives. the second part is forward to the profile guides 4, while the bugs are oriented in the directions, and as they progress they approach the cutting edges of 2 cup-shaped knives 1. Advance, the fish acts with its wedge part on the profile directions Suitable 4 1 pushes the cup-shaped knives and extends between them, sliding on guides 5 tails. At this point, bugs are cut off. The thickness of the cutting blades is determined by the size of the window formed by the cutting edge 2 of the knife, the profile guides 4 by the additional chute 7.

The cut bugs are retracted inside the cup-shaped knives, and then removed from the device, while the edges 11 of the additional tray 7 fit snugly against the inner surface 12 of the cutting edges 2, do not allow the bugs to slide down into the gap, thus ensuring complete misalignment of the scissors and separation from the carcass in the place of their attachment, where the thickness of them is comparable with the thickness of the skin of the fish.

Thanks to the fact that the additional tray is made of softer

the material than the cutting edge of the knife, and its length q is greater than the amount of possible grinding off the cutting edges of the 2 knives, ensuring reliable operation of the device.

The proposed device can also be used to cut the dorsal and anal fins of a fish. 10 The economic effect of using the device will be (approximately) 1000 rub. for one car.
