SU1433452A1 - Arrangement for deboning carcasses of poultry - Google Patents

Abstract

The invention relates to control devices for the boning of carcasses of birds and can be used in the poultry processing industry. The purpose of the invention is to increase the productivity of deboning the legs of the poultry carcasses by simultaneously deboning the lower leg and thigh of the bird without separating them. This device is driven by a drive shaft 4,

connected with a pair of horizontal rods 7 by means of a carrier 6, while the rods 7 perform a circular movement due to the direction of the shaped grooves 5 on the generator surface of the cylinder 3. This makes cutting the thigh of the knee around the knee joint with U-shaped knives 8 fixed to rods x 7 and plate blades 12 mounted on guide plates 11, after which, as a result of the movement of the leg between two pairs of guide plates 11 installed in the plane of the shaped grooves 5 1, the cylinder 3 displacements of the meat together with the tibia and femur bones of the legs. To facilitate removal of the thighs from the leg bone, the device is equipped with a circular knife 10 for cutting the ankle epiphysis 24. 4 sludge.

The invention relates to the poultry processing industry, namely to devices for separating meat from the bones of birds ducts,

The aim of the invention is to improve the performance of deboning; The bird spots of bird carcasses by means of one-time: glute deboning of the leg and thigh of the bird without j separating them.

I Fig, 1 shows the proposed I device, a longitudinal section; Fig. 2 i is the same, top view; in Fig, 3 - products obtained after deboning; in fig. 4 - loading zone of the legs in the proposed device,

Device for deboning the legs; bird carcass contains frame 1, on which: the swarm is installed drive 2, poland cy-: lindr 3, П1 i-shaft 4, cutting

 guides. On the surface of the hollow cylinder 3, two figured grooves 5, the drive shaft 4, mounted inside the hollow cylinder 3, are made, by means of the drive 6, connected to the cutting unit. The latter consists of two horizontal, rods 7, installed by one cane in the shaped grooves 5 of the cylinder B, while at the opposite end of each rod 7, an I-shaped plate knife 8 with an extended leading edge is fastened, In the loading area, under the guides 9, fixing the ankle epiphysis , placed the circular knife 10 for cutting off the pineal gland. The guide system also contains two pairs of arcuate plates 11 installed in the same plane with shaped grooves 5, provided with plate knives 12 in the loading area, and two pairs of arcuate i horizontal bars 13 mounted between plates 11 for fixing the knee joint.

The carrier 6 is connected to the horizontal rods 7 by means of a pair of vertical rods 14, mounted in vertical bushes 15, between

which rigidly fixed two horizontal sleeves 16 for the rods 7,

The ends of the rods 7, mounted in the shaped grooves 5 of the cylinder 3, contain rollers 17, included in the grooves 5, and are rigidly fixed on the rings 18 movably mounted on the pipe 19,

The disk cutter is operated by an additional drive 20. In the discharge zone for cutting off the bone of the meat on the plates 1P a pair of blade knives 21 is installed. The working head is attached to the frame 1 on the support 22,

and the system of guides is on brackets 23.

The device works as follows.

The leg is placed in the bulbar epiphysis 24 in the guides 9, and the knee joint 25 is fixed between the rods 13. The drive 2 rotates the shaft 4 with the driver 6, which drives the rods 7, which make a circular motion,

caused by the direction of the shaped grooves 5 of the cylinder 3, while the rollers 17 serve for one friction and rings 18 -; у1 for a steady movement of the rods 1,

U-shaped lamellar knives 8 roll up the thigh of their elongated edges above and below the knee joint 25 and, with simultaneous cutting of the meat, move the thigh between the blade knives 12, which cuts along the sides of the thigh above and below the knee joint 25. Disc knife 10 section The epiphysis 24 and the I-shaped knives 8 move on the rods x 7 along the plates 11 in such a way that the upper knife 8 moves over the upper pair of plates 11, and the lower knife 8 moves under the lower pair of plates 11, touching their surface.

After cutting the meat from the sides around the knee joint with 25 i-shaped knives 8 and blade knives 12, the further movement of the small bar between the plates 11 causes the movement of the mac up and down from the knee joint 25, i.e. with shin and thigh at the same time. In this case, the knee joint 25 moves between the rod guides 13.

After the pieces of meat 26 are removed from the bones 27, 28, the deboning process is completed by removing the pieces of meat to the discharge conveyor (not shown), with the lower piece falling under its own weight, and the upper piece is removed from the blade knives 21 by the rear edge of the elongated section. an i-shaped knife 8, wherein the upper knife 8 may be provided with a vertical protrusion 29. The bones 27, 28 are undividedly falling out of the guides 13 to the discharge conveyor. Then the rods 7 complete a circular motion and return to their original position, for which the figured grooves 5 are made converging and closing the circle. After the return,

elements of the working head to its original position, the process is repeated.

Claims (1)

The resulting lumpy meat can be used for the production of various semi-finished products and meat products, including baby and diet food. The use of the present invention provides high performance and reliability of operation due to simultaneous boning of the tibia and thigh of a bird without their prior separation.
