Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a raw crab foot peeling device for processing raw crabs taken directly from a fishing ground before freezing, and immediately before thawing the frozen crabs for consumption by consumers. ,
It relates to a machine device that peels crab legs on behalf of Mr. Itamae.

[0002]

2. Description of the Related Art Up until now, the only method has been to separate frozen crabs into claws, torso, and feet, and divide them into half halves in the frozen state. In particular, the technique of peeling crab legs, which is called crab-ski, is particularly difficult and requires a skilled cook, and a mechanical device requires a thin skin that envelops the meat of crab legs and the celluloid skin that covers it. Putting a knife in between is a sacred technique, and it is not very conceivable, and the only way to cook kanski is to rely on a skilled cook.

[0003]

DISCLOSURE OF THE INVENTION The present invention is a raw crab foot that can be cooked on behalf of the cook for peeling a raw crab foot used for crab skiing dishes that can only be cooked by skilled cooks. An object is to provide a peeling device.

[0004]

In order to achieve the above object, in the raw crab foot peeling device of the present invention, the crab legs separated from the body are placed on a cutting board and integrated with a fixing base. With the presser cylinder, the crab foot is pressed onto the cutting board with an appropriate force, leaving the thin skin wrapping the meat, while the knife slides left and right only the epidermis of the crab foot, and the angle of the knife is thin and celluloid. It is adjusted so that it is set between the skins, and the cutting board is moved so that the crab feet are peeled off.

Further, when the cutting board moves, the force of the crab foot pressed on the cutting board due to frictional resistance is generated on the pressing rod mounting plate pressed by the pressing cylinder. Provided with a plurality of presser bars equipped with springs so that the uneven joints of the foot can be pressed to each part with an average force, rubber or to press the crab feet directly,
When a pressing plate made of urethane material is provided and a pressing pin is further provided at one end of the pressing rod mounting plate, when the crab foot is pressed by the pressing cylinder,
The presser pin pierces through the skin of the crab foot, and the cutting board is designed to move so that the crab foot does not move from the presser board while being pressed by the cutting board.

Further, the presser plate may be provided with a screw or the like on the presser bar so that the force at the time of pressing can be adjusted by the strength of the spring attached to the presser bar. Furthermore, the partition plate is fixed on the cutting board so that the crab legs do not move sideways when pressed, and the kitchen knife can be slid while the cutting board is bisected, but the partition board does not touch even if the angle of the kitchen knife is changed. It is also effective for fixing the cutting board by cutting it so that it is not cut.

The power source for freely changing the angle of the knife may be an electric motor, air, or a hydraulic cylinder. As shown in the figure below, the knife is effectively a narrow knife with a single or double-sided arm, and if you set it on the rotary shaft and should break the blade, the screw on the rotary shaft should be used. Is preferably loosened so that it can be easily replaced.

Further, the crab legs still pressed on the cutting board are firmly fixed by the pressing pin and the pressing plate attached to the pressing rod mounting plate, and in this state, the knife is angled by the action of the knife angle cylinder. While changing, it is operated by the power of the kitchen knife slide cylinder so as to slide right and left. It is also a condition for solving this problem that the operation up to that point is performed integrally with the cutting board.

Further, a cutting board and a kitchen knife slide rail, a kitchen knife mounting base adapted to be slidable on the rail, and a cutting board slide holder at the bottom of the device in which the kitchen knife slide system mounting board is integrated. The cutting board moving screw holder is fixed, and the cutting shaft can be moved back and forth by rotating the screw shaft mounted on the fixing table by the power of motor, hydraulic pressure, or air. There is. This problem can be solved by the means described above.

[0010]

In the raw crab foot peeling device configured as described above, when the crab feet are set on the cutting board, a plurality of presser bar mounting plates are provided by the power of the cylinder integrated with the fixing base-the pressing cylinder fixed to the mounting panel. The holding rod equipped with the spring of the above works to move downward, and the holding plate presses the crab foot evenly with an appropriate force.

The crab legs, which are pressed onto the cutting board by a plurality of pressing plates, are devised so that they do not move from the pressing plate due to the frictional resistance even if the cutting board moves through the epidermis by the pressing pins and moves.

While the cutting board is divided into two, a long knife whose angle can be freely adjusted is cut into the skin of the crab, and at the same time, it moves in a groove of the knife mounting base so as to repeat the reciprocating motion to the left and right. Insert the knife slide rail, and the long knife operates by the power of the knife slide cylinder so that the angle will be set between the thin skin wrapping the meat of the crab leg and the celluloid skin, and at the same time the cutting board The cutting board slide holder is installed in the lower part, and the cutting board slide rail is inserted into the cutting board slide holder, and the screw shaft is attached to the cutting board moving screw nut holder to rotate the cutting board.

When the cutting board moves from the front to the back, the skin of the crab leg is cut off, and the presser plate is moved upward by the power of the presser cylinder and at the same time, the skin of the crab leg is pierced and fixed so as not to move from the presser plate. The presser pin operates to separate the crab foot from the position of the presser plate by the force of the spring of the presser pin.

The crab feet remaining on the cutting board remain in the position opposite to the cutting board that was initially set, and the cutting board acts so as to move back to the initial position.
