Description

The invention relates to the field of engineering for the food industry, in particular to devices for processing poultry carcasses, and can be used in the poultry processing industry in poultry processing lines, including quail.

Known devices for cutting cloacas of carcasses of a bird, consisting of a bed, a shaft, cams, a rotor carrying upper working bodies with a cylindrical knife and lower working bodies with elements for fixing the tail and carcass of the bird in a certain position (see Johnson brochure, exhibition Agroprodmash - 2013).

The disadvantages of these devices are the need to fix the tail with a vacuum device and remove the cut cloaca from the inner cavity of the cylindrical knife by supplying pressure water to the inner cavity of the cylindrical knife, which greatly complicates the design of the devices.

The closest technical solution is a device for cutting cloaca of poultry carcasses according to the patent of the Russian Federation No. 2483555, MKI A22C 21/06 from 11/22/11.

The device consists of a bed on which a shaft is mounted motionless, carrying cams, a rotor and a drive sprocket. The rotor contains an upper working body mounted on rods with a slider in which hollow gears with a cylindrical knife are mounted. The rotor is equipped with a fixed guide included in the internal cavity of the gear and knife. The lower working body is mounted on the rods and is equipped with hinges for fixing the carcass and tail and the chest clip.

The traction member of the overhead conveyor drives the drive sprocket, which transmits the rotation to the rotor. Pendants with poultry carcasses fit the device and are located opposite the working bodies. With further rotation of the rotor, the lower working body descends along the rods to the carcass, while one of its loops and a breast clip fix the carcass, and the second loop fixes the tail, placing it under the cylindrical knife of the upper working body. The upper working body, lowering, cuts out the cloaca with a rotating knife, while the fixed guide remains in place, as a result of which a cavity is opened in the cylindrical knife, into which the cut cloaca enters. Then the upper working body rises to its original position, and the fixed guide pushes out the cloaca cut from the cavity of the cylindrical knife, leaving it hanging from the back of the carcass. Elements of the lower working body release the carcass and it leaves the device.

The disadvantage of this device is the inability to process on it non-standard carcasses of birds, differing in weight by more than 10%. (For example, at the present time, in industrially grown quails, carcasses may differ in weight by 50-100%). The sizes of such carcasses can differ to such an extent that when loops and presses of the lowering lower bodies of carcasses with small and large mass are fixed, the carcass of the carcass is incorrectly oriented, as a result of which the cylindrical knife misses the carcass and cuts out part of the carcass, which leads to meat loss or damage to the intestines and contamination of the carcass by its contents, which leads to an increase in labor costs, because additional refinement of carcasses is needed. In addition, the loop that fixes the tail, located on top, does not hold it in carcasses of small sizes, the tail starts to rotate, is pulled inside the knife and cut off with the cloaca, which also leads to the loss of raw meat.

The technical task of the present invention is to expand the range of sizes (mass) of simultaneously processed poultry carcasses, reducing losses of raw meat and reducing labor costs during further processing of non-standard carcasses.

The solution to the technical problem is achieved by the fact that in the device containing the frame, the drive sprocket, a fixed shaft with cams and a rotor carrying movable upper and lower working bodies on the rods with an abdominal clamp loop, a carcass chest clamp and a tail fixing loop, the lower working body is additionally equipped with movable two-arm levers for raising the carcass and a fixed roller, the loop of the clamp of the abdominal cavity of the carcass is fixedly mounted relative to the two-arm levers and rods and is equipped with a plate with ribs located per d double-arm lever.

The technical result is achieved by the fact that in the proposed device, the lower working body further comprises movable two-shouldered levers for raising the carcass and a fixed roller, the loop of the clamp of the abdominal cavity is fixed with respect to the two-shouldered levers and rods and is equipped with a plate with ribs located in front of the two-shouldered levers, which allows you to accurately orient the cut cesspool under a cylindrical knife, regardless of the size (weight) of the carcass of a bird grown industrially, to exclude the rotation of the tail during rotation the cylindrical knife and therefore cut the cloaca without damaging the carcass or the intestine, thereby increasing the quality of the non-standard processing carcasses and reducing the loss of meat raw material and labor costs during further processing of poultry.

Comparative analysis with the prototype shows that the inventive device is characterized by a constructive implementation of the lower working body, which improves the quality of processing of a non-standard product and reduces the loss of raw meat and labor costs during further processing of poultry. Thus, the claimed device meets the criterion of "novelty."

Comparison of the claimed solution not only with the prototype, but also with other technical solutions, did not reveal in them the signs that distinguish the claimed solution from the prototype, which allows us to conclude that the criterion of "significant differences".

The technical solution is illustrated by drawings.

The device consists of a bed 1, on which the shaft 2 is fixedly mounted, bearing cams 3 and the rotor 4, connected with a pin 5 to the drive sprocket 6. The rotor 4 contains an upper working member 7 with rods 8. A slide 9 is installed on the rods 8, in which a hollow gear 10 is mounted that carries a hollow cylindrical knife 11. The slider 9 is equipped with a roller 12. A gear sector 13 is fixed to the shaft 2. The rotor 4 contains a fixed guide 14 that enters the inner cavity of the gear 10 and knife 11.

The lower working body 15 is equipped with a chest clip 16, in the form of a swinging pusher with a roller 17 mounted on the axis 18, and contains rods 19, on which the loop of the clamp of the abdominal cavity 20 with the plate 21 and ribs 22 is fixedly mounted, the slider 23 is mounted movably mounted on it on the axis 24 with two two-shouldered levers 25, having bends “a” and a roller 26. A fixed roller 27 is installed between the rods 19, which interacts with the ends “b” of the two-shouldered levers 25. The pendants 28 for the carcasses of the bird 29 are mounted on the carriages 30 of the overhead conveyor.

The device operates as follows.

The carriage 30 of the overhead conveyor rotates the drive sprocket 6, which, through finger 5, transmits rotation to the rotor 4. Pendants 28 with bird carcasses 29 fit the device and are located opposite the working bodies 7 and 15. With further rotation of the rotor 4, the slider 23 interacts with the roller 26 sec cam 3, rises up, while the ends "b" of the two-arm levers 25, interacting with the stationary roller 27 are moved apart, turning around the axis 24, and the bends "a" of the two-arm levers 25 converge towards each other under the legs of the carcass 29 and raising the carcass 29, press it to the fixed loop 20. The breast clip 16, interacting with the roller 17 with the cam 3, presses the carcass 29 with its back to the plate 21 and the tail to the ribs 22. At the same time, the plate 21 protects the back of the carcass 29 from damage by movable two-arm levers 25. Thus , the abdominal cavity and cesspool of all carcasses, regardless of their size (mass), are at the same distance from the cutting edge of the cylindrical knife 11, because the fixed loop 20 is installed at a fixed distance "in" from the cutting edge of the cylindrical knife 11 (see Fig.3, 4, 5, 6). In this case, the tail of the carcass 29 is fixed from turning by the ribs 22 and the chest clip 16. After this, the upper working body 7 lowers down, while the guide 14 remains in place, as a result of which the inner cavity opens in the cylindrical knife 11 (see Fig. 4) and the gear 10, interacting with the gear sector 13, rotates together with the knife 11, which cuts the cloaca, delving into the carcass at a fixed distance "d" (see Fig. 4, 6), which excludes damage to the intestine, without damaging the carcass, because the cesspool is oriented exactly under the knife 11 by the lower working member 15. The cut out cesspool is located in the inner cavity of the knife 11. Then the upper working part 7 rises to its original position, while the fixed guide 14 pushes out the cut out cesspool from the cavity of the cylindrical knife 11, which remains hanging from the back carcasses 29 (see Fig.7). The movable elements 16, 23 and 25 of the lower working body 15 are returned to their original position, freeing the carcass 29, and it leaves the device.

Thus, improving the quality of processing non-standard poultry carcasses, reducing losses of meat raw materials and reducing labor costs during further processing of poultry carcasses is ensured by the design of the lower working body, which allows using the movable two-arm levers for lifting the carcass and the fixed roller, the loop of the abdominal cavity with the plate and ribs, mounted motionless relative to two-shouldered levers and rods and located in front of two-shouldered levers, precisely orient the cut out cesspool under the cylindrical knife by one kovom distance "a" from the cutting edge of the knife irrespective of the size (weight) poultry carcass grown industrial method to eliminate rotation of tail by the rotation of the cylindrical knife and ensure uniform depth "d" of the knife into the carcass of call, i.e., cut cesspool without damaging the carcass or intestines.
