The invention relates to the poultry processing industry, namely, devices for removing bone from the bone of the small bird.

The purpose of the invention is to improve the quality of processing and increase the reliability of the device.

FIG. 1 shows the device, general view, section; in fig. 2 - device at the time of completion of the process of removing chicken from the bones of the leg.

The device comprises a cutting element 1, a gripping device 2 for fixing the leg, an actuator (not shown), two hollow cylinders 3, coaxially mounted with reciprocating motion. The cutting element 1 is a hollow cylinder with a cutting edge that is coaxially mounted on one from hollow cylinders 3 with reciprocating motion. Each hollow cylinder 3 has a conical shaped groove 4 at the end, and a fixed stop 5 is installed in the cavity of each cylinder 3.

The device is also equipped with guides 6, a pusher 7, a Y-knife.

8dl cutting epiphysis 9 thigh 10.

The device works as follows.

Okor ochek 10 ankle epiphysis

9 is installed in guides 6, which can be made in the form of several pairs of arcuate broken or straight rods, plates, etc. At the same time, the ankle epiphysis is located above the upper pair of guides 6, and the knee joint is between the middle and lower pair. The pusher 7, making a swinging movement received from the drive, moves the legs 10 along the guides 6, while the Y-shaped knife 8 cuts off the epiphysis 9. The leg 10 is placed in the gripping device 2 and fixed. Then, the hollow cylinders 3 receive translational movement from the drive and approach each other to a contact. In this case, the bones 11 of the thigh 10 enter into the cavities of the cylinders 3, and the muscle tissue 12 is displaced to the knee joint.

In this case, the conical groove 4 contributes to a more complete movement of the mac without destroying the knee joint.

After eating the hollow cylinders 3 in contact, the cutting element 1 is set in motion and cuts muscle tissue from the knee joint with a whole piece. Thereafter, the hollow cylinders 3 and the cutting element 1 take the initial position, and the cycle repeats after removing the bone and the bone, the jogging of which in the cavity of the cylinders 3 is prevented by fixed stops 5.

The device allows to improve the quality of processing, since the meat is removed with a whole piece with the internal cavity simultaneously with the femur and tibia of the leg of a chicken without their separation, which is impossible on known devices, as well as with manual

boning.

The design of the device is simple, which provides increased reliability of the device in operation.

Claims (2)

1. A device for removing meat from the bones of the chicken roe, containing a cutting element for cutting meat, a gripping device for fixing the leg, and a drive, characterized in that, in order to improve the quality of processing and increase the reliability of the device, it is equipped with two hollow cylinders coaxially mounted with the possibility of reciprocating movement to move the bone from the bones of the leg to the knee joint, and the cutting element is a hollow cylinder with a cutting edge, coaxially mounted on one of these cylinders with the possibility of reciprocating movement to cut the meat from the knee joint. 2. The device according to claim 1, that is, so that each hollow cylinder for The shearing device has a conical shaped groove at the end, and a fixed stop is installed in the cavity of each of these cylinders.
