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

Known devices of venting poultry carcasses comprising a frame, a shaft, Cams, rotor, bearing the upper working bodies with a cylindrical blade and lower working bodies with elements for fixing the tail and poultry carcasses in a certain position (see the prospectus of the company Johnson, the exhibition Agroprodmash - 2013).

The disadvantages of these devices are the need of fixing the tail with a vacuum device and removing cut venting from the inner cavity of the cylindrical blade with the help of flow into the internal cavity of the cylindrical knife water under pressure, which significantly complicates the design of the device.

The closest technical solution is a device for cutting out the vent of the poultry carcasses by the patent RF №2483555, MKI A22C 21/06 from 22.11.11.

The device consists of a frame, on which are fixedly mounted shaft carrying Cams, rotor and drive sprocket. The rotor includes a top working body mounted on the rod with the slide, in which are mounted a hollow gear with a cylindrical blade. The rotor is provided with a fixed guide, which is included in� the internal cavity of the gear and knife. Lower working body mounted on the rods and hooks are fitted to the fixation of the carcass and tail and clamp the chest.

Traction body overhead conveyor causes the rotation of the drive sprocket, which transmits the rotation of the rotor. Pendants with whole birds come to the device and are located opposite of the working bodies. Further rotation of the rotor the lower the working body is lowered on the rods on the carcass, with one loop and clamp the breast is fixed to the carcass, and the second loop locks the tail, placing it under the upper cylindrical blade of the working body. Top working body, sinking, cut by a rotating knife cesspool, with a stationary guide rail remains in place, resulting in a cylindrical knife open cavity, into which is carved the cloaca. Then upper body work rises to its original position, and the fixed guideway is pushed out from the cavity of the cylindrical knife cut out the body, leaving it hanging on the back of the carcass. The elements of the lower working body release the carcass and she comes out of the device.

The disadvantage of this device is the inability to handle it custom of birds that differ in mass by more than 10%. (For example, currently have grown industrially quail, carcass may differ in weight by 50-100%). Size�ry of such carcasses may differ in the extent when fixing hinges and clamp the chest sinking lower working parts of carcasses with small and large mass occurs incorrect orientation of the tail carcasses, resulting in a cylindrical knife misses the tail and cuts a portion of the carcass, leading to the loss of meat or damage to the intestines and the contamination of a carcass its contents, resulting in increased labor costs because of the required additional refinement of the carcasses. In addition, the loop that secures the tail, lying on top, not to hold her at the carcasses of small size, the tail starts to rotate, delayed inside the knife and is cut together with the cloaca, which also leads to the loss of raw meat.

The technical object of the present invention are the extension of the range of sizes (masses) of concurrently processed poultry carcasses, reducing losses of raw meat and reduce labor costs in the further processing of non-standard carcasses.

The solution of a technical problem is achieved in that the device comprising a base frame, a drive sprocket, a stationary shaft with Cams and a rotor, a carrier movable on rods top and bottom working bodies with a loop of a clip of the abdominal cavity, pressing the breast of the carcass and loop fixing tail, lower body work is additionally equipped with a movable two shoulders levers lifting the carcass and the fixed roller, loop clamp br�shny carcass body cavity mounted in a fixed position relative to two shoulders of levers and rods and is provided with a plate with ribs, located in front of the two shoulders levers.

The technical result is achieved in that in the proposed device the lower working body further comprises a movable two shoulders levers lifting the carcass and the stationary roller, loop clamp the abdominal cavity mounted in a fixed position relative to two shoulders of levers and rods and is provided with a plate with ribs placed in front of two shoulders levers that allows you to accurately align cut cesspool beneath cylindrical knife regardless of the size (mass) of a poultry carcass, grown industrially, avoid turning tail when rotating cylindrical knife and, therefore, cut the body without damage to the carcass or intestines thereby increasing the quality of processing non-standard carcasses and reduces the loss of meat raw materials and labor costs in the further processing of poultry.

Comparative analysis with the prototype shows that the claimed device differs constructive execution of the lower working body, which improves the machining quality custom product and to reduce the loss of meat raw materials and labor costs in the further processing of poultry. Thus, the claimed device meets the criterion of "novelty."

Comparison of the proposed solutions not only prototype, but also with other technical solutions that are not found in them �rsnake, distinguishing the claimed solution to the prototype that allows to conclude that the criterion of "substantial differences".

The technical solution is illustrated by drawings.

Fig.6 shows a view B (Fig.3 and 4), showing the mutual arrangement of the working elements after fixing the carcass and cut the cloaca.

Fig.7 depicts birds with carved cloaca after exit from the apparatus.

The device consists of a frame 1 on which is fixedly mounted a shaft 2, which carries the Cams 3 and rotor 4 connected to the finger 5 with a drive sprocket 6. The rotor 4 includes a top working body 7 with the rod 8. The rod 8 is mounted to the slider 9, which includes a hollow gear 10, carrier of the hollow cylindrical knife 11. The slider 9 is equipped with a roller 12. On the shaft 2 is fixed a toothed sector 13. The rotor 4 with�keeps stationary guide 14, a member of the inner cavity of the gear 10 and the blade 11.

Lower working body 15 is equipped with a clamp the chest 16 in the form of an oscillating pusher with roller 17 mounted on the axis 18, and contains a rod 19, which are fixedly mounted hinge clamping of the abdominal cavity 20 with the plate 21 and ribs 22, is movably mounted a slide 23 mounted thereon on an axis 24 two two shoulders of the levers 25 with the legs "a" and the roller 26. Between the rod 19 is mounted stationary roller 27 that interacts with the ends "b" of the two shoulders of the levers 25. Suspension 28 for broilers 29 mounted on the carriage 30 of the overhead conveyor.

The device operates as follows.

The carriage 30 of the overhead conveyor driven to rotate the drive sprocket 6, which through the finger 5 transmits the rotation of the rotor 4. Suspension 28 with the carcasses of the birds 29 are suitable to the device and are located opposite of the working bodies 7 and 15. Further rotation of the rotor 4, the slide 23, interacting roller 26 with the Cam 3, is lifted upwards at the ends "b" of the two shoulders of the levers 25, interacting with the stationary roller 27 are moved apart, turning around the axis 24 and folds "and" two shoulders of the levers 25 converge toward each other under the legs of the carcass 29 and, lifting the carcass 29, press it to a stationary loop 20. Clamp the chest 16, interacting roller 17 with the Cam 3, presses the carcass 29 back to the plate 21 and GU�coy to the fins 22. With the plate 21 prevents the back of the carcass 29 from damage moving two shoulders of the levers 25. Thus, the abdominal cavity and cloaca of all carcasses, regardless of their size (mass) are at the same distance from the cutting edge of the cylindrical knife 11, since the stationary loop 20 is installed at a fixed distance "b" from the cutting edge of the cylindrical knife 11 (see.3, 4, 5, 6). The tail of the carcass 29 is locked against rotation by the ribs 22 and clamp the chest 16. After that, the upper operating body 7 is lowered, the guide 14 remains in place, resulting in a cylindrical knife 11 opens to the internal cavity (see Fig.4), and gear 10, interacting with the toothed sector 13, rotates with the knife 11, which cuts out the sewer, delving deep into the carcass at a fixed distance "d" (see Fig.4, 6), precluding damage to the bowel, without damaging the carcass, because the cloaca is focused precisely under the knife 11 bottom of the screed 15. Cut the cloaca is located in the inner cavity of the knife 11. Then the top working body 7 is raised to its original position, wherein the stationary guide 14 is pushed out from the cavity of the cylindrical knife cut 11 cesspool, which remains hanging on the back of the carcass 29 (see Fig.7). The movable elements 16, 23 and 25 of the lower working body 15 comes�tsya to the original position, freeing the carcass 29, and she comes out of the device.

Thus, improving the quality of custom processing of poultry carcasses, reducing losses of raw meat and reduce labor costs in the further processing of poultry carcasses is ensured by the design of the bottom of the working body, which allows using the mobile two shoulders levers lifting the carcass and the stationary roller, loop clamp the abdominal cavity with the plate and ribs mounted fixedly relative to two shoulders of levers and rods and placed in front of the two shoulders levers, precisely target cut cesspool beneath a cylindrical blade at the same distance "b" from the cutting edge of the knife, regardless of the size (mass) of a poultry carcass, grown industrially, to exclude the turning tail when rotating cylindrical knife and provide the same depth "d" of entry of the knife inside the carcasses, i.e. to cut out the body without damage to the carcass or intestines.
