Description

Automatic dropout and coating yarn separator for harvesting submersible oysters The present invention relates to an automatic detachment and coated yarn separator for suspended oyster harvesting, and more specifically, to an automatic detachment and coated yarn separator for suspended oyster harvesting in which the lifting roller is formed of acetal to prevent damage caused by seawater and to excellently prevent slippage of the coated yarn line, thereby enabling stable use. Generally, due to the development of aquaculture technology, various fish, shellfish such as oysters and sea squirts, and seaweed such as kelp are being farmed in large quantities in the sea. This aquaculture system is configured by installing suspension lines at regular intervals on the main line and allowing the lines to hang down into the sea so that the aquatic products can attach and grow. Furthermore, harvesting requires a towing process to pull up the main line and coating line from the seabed using a crane installed on a barge. Since workers must simultaneously cut the coating line from the main line with scissors after towing, they easily experience fatigue, and as the rate of safety accidents increases, there is a demand for a harvesting device that can safely harvest farmed oysters using an automated method. As prior art to the above-mentioned harvesting device, an automatic harvesting device for farmed oysters and sea squirts has been registered in Korean Registered Patent Publication No. 10-2779245. This prior art comprises a harvester body in which a pair of support arms are spaced apart in an upright position to allow a suspended line, including cultured oysters and sea squirts, to enter, and an entry space is formed between them; a pair of lifting rollers arranged between the support arms, gears formed on their outer surfaces to mesh with each other to grip the suspended line, and configured to rotate in opposite directions to pull and transport the suspended line upward; a pair of scrap rollers arranged facing each other below the lifting rollers and configured to rotate in opposite directions to strike and separate the aquatic products attached to the suspended line; and an upward propulsion module arranged below the scrap rollers to transport the aquatic products attached to the suspended line upward, wherein the upward propulsion module comprises a pair of shafts rotating in the same rotational direction as the pair of lifting rollers and wing plates attached longitudinally to the outer surfaces of the shafts and protruding outward, the suspended line is lifted between the pair of shafts, and the pair of shafts rotate It is a configuration in which the wing plates are spaced apart so that their rotation radii do not overlap during operation. However, the lifting roller of the aforementioned prior art is made of metal, which causes damage such as the breaking of the coated yarn line and leakage into the sea. In addition, there is a problem in that the lifting roller is made of metal and cannot prevent damage from seawater. In addition, there is a problem in that the angle of the scrap roller cannot be adjusted, making it inconvenient to use. FIGS. 1 to 3 are drawings showing a suspended oyster harvesting automatic detachment and coating sand separator according to an embodiment of the present invention. FIGS. 4 and 5 are drawings showing the lifting roller of a submerged oyster harvesting automatic detachment and coating sand separator according to an embodiment of the present invention.
