Abstract

This device is used for cutting the heel joints of the legs of poultry after slaughter. The legs of the poultry are suspended and fed. The device includes: a limiter, which is at an angle to the feeding direction, a A long cutting knife, which travels beyond the limiter, is driven to rotate about an axis which is forward in the direction of feed and lateral to the limiter.

Description

The present invention relates to a device for cutting the heel joints of the legs of poultry after slaughter, the legs of which are fed in suspended.

Since the demand for the legs of poultry is increasing day by day (such as the needs of fast food), there is a need for a cutting device, which can accurately cut off the poultry legs from the heel joint. This operation has heretofore been carried out manually, i.e. by hand holding the poultry legs to feed a rotating cutter; this method is time consuming, costly and a very dangerous processing operation.

The present invention proposes a device suitable for this task. The device according to the present invention includes: a limiter, which is at an angle to the feed direction; and an elongated cutting knife, whose travel exceeds the limiter, and which is driven to rotate around an axis of rotation located at The front of the feed direction and the side of the limiter.

With the device of the invention, the heel joint of the bird is positioned between one side of the restraint and the other side of the elongated rotating cutter, after which the cutting stroke of the cutter exceeds the leg portion, using a Pressurized part, the positioning operation is carried out, this slender pressurized part can be rotated through an angle around the rotation axis, it is connected to the slender cutting knife through a spring part, and its distance from the cutting knife is very small close. The pressurized part, under spring action, contacts and presses against the leg before the cutting knife reaches the leg, placing the heel joint of the leg at the limiter and compensating for differences in leg length.

The limiter preferably includes two cutter segments at an acute angle to the feed track. Before the elongated cutting knife completely cuts through the heel joint, the skin on the front side of the heel joint is cut open with the two cutting knife parts, thus improving the cutting process.

The cutting edge of the elongated cutting knife is preferably designed in such a shape that the blade starts from near the axis of rotation and gradually slopes backwards, so that when it moves, the cutting edge is always in a substantially transverse direction perpendicular to the direction of motion. state.

The rotating cutter is preferably driven synchronously with the crawlers on which the birds are suspended, so that it is ensured that the cutter is in a position out of the feed channel when the legs are delivered.

The present invention is described with reference to accompanying drawing, and accompanying drawing is as follows:

Fig. 1 is the top view structural diagram of device of the present invention;

Fig. 2 is the side view structural diagram of device of the present invention;

Figure 3 is a first perspective view of an embodiment of the present invention;

Figure 4 is a second perspective view of an embodiment of the present invention.

The processed poultry limbs are hung on the conveyor crawler 2 (see Fig. 2) with poultry legs 1, and are sent forward along the dotted line 4 shown in Fig. 1 in the direction shown by arrow 3. The device used to cut off the heel joint includes a bracket 6, which is fixed on the bracket part 5 (as shown in the schematic diagram of the structure), and the bracket has two elongated feed guide rails 7 and a limiter 8. Two cutting knives 8a, 8b are housed in the device, and the blade of this cutting knives forms an acute angle with crawler belt 4. The device also includes a rotatable, vertically installed passive drive shaft 9, which is arranged in a cross shape with the feed track, and an elongated cutting knife 10 is installed at the lower end of the shaft, and the shape of the blade 10a of the cutting knife is It is recommended that the cutting edge gradually slopes backwards starting close to the axis 9 . Above the cutting knife, there is a bearing sleeve 11, which is free to rotate around the shaft, and it is mounted between the cutting knife 10 and a retaining sleeve 12 (above the cutting knife and fixed on the shaft) Between; the bearing sleeve 11 is equipped with a slender pressurized part 13, the part is connected with the cutting knife 10 through the tension spring 14; the limiter 15 cooperates with the adjustable stud 16, and the stud 16 is installed in the cutting The knife 10 limits the angle by which the pressing part 13 can rotate about the axis 9 relative to the cutting knife 10 .

The operation process of this device is as follows:

The shaft 9 is continuously driven in the direction indicated by the arrow 17 (driven by the crawler belt 2, the driving device is not shown), due to the result of the rotation, between the position of the crawler belt driving device with the poultry suspended and the cutting knife correspondingly rotated with it, The resulting "phase difference" is adjustable. The mounting position of the device, i.e. the distance from the conveyor belt 2, can be adjusted so that the poultry leg part is fed with its heel joint to the height of the limiter 8, which includes a cutting knife 8a, 8b. Thus, the joint part is elastically pressed against the limiter by the pressing part 13, when pressed into the V-shaped space by the pressing part, the joint is positioned and the difference in the length of the poultry legs is compensated. The cutting knives 8a, 8b cut into the skin and then the heel joint is severed by the blade of the cutting knife 10 which, when moved, goes beyond the heel joint. The upper part 18 of the leg (the bird toggle) is transported along the conveyor tracks and the lower part 19 of the leg falls into a discharge chute (not shown).
