Description

Devices for cutting crab limbs are known, including a main chain conveyor with clamps, a knife mechanism for cutting limbs, a nozzle for hydraulically pushing meat, hydraulic chutes, receiving trays and a system for supplying water.

The proposed device allows separate removal of meat from the chopped armor parts of the extremities and increases labor productivity.

The peculiarity of the device lies in the fact that in addition to the main one there are three auxiliary chain conveyors with clamps; Each conveyor at the end has a hydraulic unit with nozzles.

The hydraulic unit of the lower horizontal conveyor is designed to push the meat out of the rosette, the hydraulic unit of the inclined conveyor to push the meat out of the knee segment, and the hydraulic unit of the horizontal upper conveyor with the upper branch positioned at the level of the upper branch of the main conveyor is designed to push the meat out of the segment thick ma sa. At the end of the main conveyor, a hydraulic unit is installed to push the meat out of the segment of the thin meat, and in its loading area, under the clamps, a rotary cross, having curved ends, is mounted.

FIG. 1 shows a side view of the device; in fig. 2 - its front view; in fig. 3 - its plan view; in fig. 4- hydraulic unit for pushing the meat out of the segment.

On the welded frame / there are four chain conveyors 2, 3, 4 and 5, on the links of which the clips 7 for crab limbs interacting with copiers are mounted. At the end of each conveyor, a hydraulic unit is installed to push the meat out of the chopped armor parts of the extremities, including a shaft 8, on which a cross 9 is fixed, driven by a chain conveyor. On the spider 9, there are nozzles 10 into which water is pushed through the holes drilled in the center of the shaft 8 to push the meat out of the joints.

The hydraulic unit // of the main conveyor 2 serves to push the meat out of segment 12 of the thin meat. At the level of the upper branch of the main conveyor is the upper branch of the upper horizontal conveyor 5, the hydraulic unit 13 of which is designed to push the meat out of segment 14 of the thick meat. The hydraulic unit 15 of the inclined conveyor 4 serves to push the meat out of the cap 16 segment, and the lower horizontal conveyor 5 has a hydraulic unit 17 to push the meat out of the rosette 18.

A knife mechanism 19 with seven knives 20 for chopping limbs into segments and for separating the rosette is installed on the path of movement of the claws with crab limbs.

The device is equipped with a water supply system 21.

The crab limbs are manually fed from the hopper 22 to the opened clamps of the conveyors. The swiveling cross 23 installed in the loading zone with its curved ends straightens the limb of the crab in the clamps 7, which, when they exit to the straight line, close and clamp each segment of the limb of the crab. Further, the limb of the crab is cut by knives 20 into its segments of thick meat, knee, thin meat, which are conveyed by conveyors 2, 3 - 4 to hydraulic units, and the rosette falls into tray 24, from where it enters the clamp of conveyor 5 and is transported last to the hydraulic unit 17.

Knocked out of the severed limbs m with enters the foster

the trays 25, and the waste (armor and felled joints) are removed from the device using a hydraulic chute 26.
