Abstract

PURPOSE:To automate an oyster-shucking operation, eliminate hard labor, improve the efficiency and reduce the shucking cost by elastically clamping an oyster with an oyster-clamping means and opening the shell of the oyster using a specific method in the course of moving the clamped oyster in water. CONSTITUTION:An oyster K is elastically clamped with an oyster-clamping means 20 on a conveyor 1 in a state directing the back of the oyster downward and coinciding the plane including the outer circumference of the shell to the vertical plane including the moving direction of the conveyor and is transferred in water keeping the above state. In the course of moving in water, a rotating grinder 11 is pressed to both sides of the oyster K at a position corresponding to an adductor muscle or its neighborhood to grind the shell SH and separate the adductor muscle from the shell SH. Thereafter, the slightly opened part at the tip of the belly part is pressed against the sharp end of a wedge-shaped shell-opening member 27 to thrust the opening member into the shell and open the shell SH. A fluid is ejected from a nozzle 28 into the opened shell to extract the meat from the shell SH.

(Problem to be solved by the invention) In the above-mentioned manual process, it takes 1 oyster on average to peel one oyster.
It is inefficient as it takes 0 seconds, and at the same time, it is extremely harsh and can cause your body to get cold as you are working in water during the cold season, as well as pain in your legs and lower back and chapped hands due to working in a sitting position for a long time. Because of the difficult working conditions, high wages are required, resulting in high costs.Furthermore, the work is concentrated over a period of time, making it difficult to secure labor.There are many adverse conditions that make this work extremely difficult. This is the biggest problem faced by aquaculture farmers, and various attempts have been made to mechanize and automate the problem in order to overcome this problem. This was considered the industry's biggest challenge.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention is to place an oyster belonging to the class Bivalvia on an oyster holding means provided on a conveyor, with the back side down and a plane including the outer periphery of the shell. The oyster is moved underwater in the aquarium while being clamped almost in line with the vertical plane including the direction of travel of the conveyor, and during this underwater movement, the oyster is rotated from both sides of the oyster to the outside of the closed shell muscle position and in the vicinity. By grinding the shell with a grindstone, the shell is separated from the shell, and the opening at the tip of the abdomen, which is slightly opened due to this cutting, is fitted into a wedge-shaped opening member from the pointed end to open the shell. , is an automatic scraping method that injects fluid into the closed shell muscles to release the body from the shell.

In addition, a conveyor that moves underwater in an aquarium with a portion exposed in the air, a fixed claw that protrudes upward and a movable claw that is biased in the direction of the fixed claw provided on the top surface of the conveyor, are provided on the conveyor. A grinding wheel that rotates in the horizontal direction is arranged to have a diameter smaller than that of the grinding wheel, and a grinding wheel that rotates in a horizontal direction corresponding to the positions of the closed shell muscles on both sides of the oyster moving in the water. It is attached to a vertical whetstone shaft along with a regulating ring that restricts the cutting depth of the whetstone by hitting the shell of the oyster, and the whetstone shaft is biased in the direction of the oyster. multiple pairs of grinding means provided at different vertical positions;
A wedge-shaped opening member with an acutely pointed end on the side where the oyster approaches is provided along the traveling direction of the conveyor at the position where the small opening at the tip of the abdomen of the oyster passes through. Then, the fluid is injected into the closed oyster,
A nozzle for removing the shell from the shell, and a clamping and opening member provided along the traveling direction of the conveyor for opening the movable claw in a counter-biasing direction in order to remove the shell from the scraping and clamping means. This is an automatic scraping device.

When this happens, the action of the obturator muscles that close the shell disappears, and the ligaments on the back try to open the shell, but since the shell is being held elastically by the scraping and pinching means, the abdomen at the upper end resists the elastic force. (0) In this state, the conveyor advances, the small opening fits into the sharp point at the tip of the opening member, and as the width expands in a wedge shape, the movable claw of the clamping means becomes a biasing force. Push it open and open it wide.

(1) Oysters belonging to the class Bivalvia were clamped with their backs down on the oyster clamping means provided on the conveyor, with the plane including the outer periphery of the shells approximately aligned with the vertical plane including the traveling direction of the conveyor. During this underwater movement, a rotating grindstone is applied from both sides of the oyster to the outside of and near the position of the shell muscle, and the shell is ground, thereby cutting the shell muscle from the shell. The shell is opened by inserting the opening at the tip of the abdomen, which is slightly opened by cutting, into a wedge-shaped open shell member from the pointed end side, and the body is expelled from the shell by injecting fluid into this open shell. Features an automatic scraping method.

(2) A conveyor that moves underwater in an aquarium with a portion exposed in the air, a fixed claw that protrudes upward and a movable claw that is biased in the direction of the fixed claw provided on the top surface of the conveyor. , a grinding wheel rotating in the horizontal direction is provided with a grinding wheel having a diameter smaller than that of the grinding wheel, corresponding to the oyster clamping means facing each other in a direction perpendicular to the traveling direction of the conveyor, and the positions of the closed shell muscles on both sides of the oyster moving in the water. It is attached to a vertical whetstone shaft along with a regulating ring whose outer periphery hits the oyster shell and regulates the cutting depth of the whetstone, and the whetstone shaft is biased in the direction of the oyster in order to correspond to the size of the oyster. A plurality of pairs of grinding means are provided at different vertical positions of the grindstone, and a oyster is provided along the traveling direction of the conveyor at a position where the small opening at the tip of the abdomen of the oyster, which has been made small by cutting the closed shell muscle, passes through. a wedge-shaped opening shell member having an acutely pointed end on the side where the shell approaches; a nozzle for injecting fluid to the open shelled oyster to remove the shell from the shell; An automatic scraping device comprising: a clamping and opening member provided along the traveling direction of the conveyor for opening the movable claw in a counter-biasing direction.
