The present invention relates to an apparatus for cutting a net and a rope for a ship, which, when marine waste such as a waste fishnet and a waste rope is wound around a propulsion device of a ship, smoothly cuts the marine waste, thereby eliminating hindrances in ship navigation caused by the winding of the marine waste in advance and enabling safe navigation. Furthermore, malfunctioning may be prevented from being caused by an overload during the rotation of a propeller. To this end, the apparatus for cutting a net and a rope for a ship according to the present invention is the apparatus for cutting a net and a rope for a ship, which cuts marine waste wound around a propulsion device by being installed at the propulsion device of a ship, which comprises a propeller shaft which is extended out of a stern tube installed at the lower portion of the stern of a ship, and a propeller installed at the rear end portion of the propeller shaft. To this end, the present invention comprises: a rotating cutter member including a hub provided in a circular ring shape which is rotated by being coupled to the outer surface of the propeller shaft, a first rotation blade which is extended in the radial direction of the hub and has a serrated blade formed in the circumferential direction on the outer circumference, and a second rotation blade which is formed at the hub to be in parallel with the first rotation blade and has a blade formed on the outer circumference; and a fixing cutter member which is installed to be fixed at the stern tube, and has a cutting unit formed in a sharp blade shape to cut marine waste by being linked with the rotating cutter member after being installed at the rear end portion to be close to the rotation cutter member.

    본 발명은 선박의 추진장치에 폐어망이나 폐로프와 같은 해양폐기물이 감길 경우, 해양폐기물을 원할하게 절단함으로써 해양폐기물의 감김으로 인한 선박 운항의 저해요소를 사전에 제거하여 안전한 운항을 할 수 있고, 추진기의 회전시 과부하로 인한 고장 발생을 방지할 수 있는 선박용 그물 및 로프 커팅장치에 관한 것으로, 본 발명에 따른 선박용 그물 및 로프 커팅장치는, 선박의 선미 하부에 설치되는 스턴튜브의 외측으로 연장되는 프로펠러샤프트와, 상기 프로펠러샤프트의 후단부에 설치되는 프로펠러를 포함하는 선박의 추진장치에 설치되어 추진장치에 감기는 해양폐기물을 커팅하는 선박용 그물 및 로프 커팅장치에 있어서, 상기 프로펠러샤프트의 외면에 결합되어 회전하는 원형 링 형태로 된 허브와, 상기 허브의 반경방향으로 연장되게 형성되며 외주연부에 원주방향을 따라 톱니 형태의 칼날이 형성된 제1회전블레이드와, 상기 허브에 상기 제1회전블레이드와 나란하게 형성되며 외주연부에 칼날이 형성된 제2회전블레이드를 포함하는 회전커터부재; 및, 상기 스턴튜브에 고정되게 설치되며, 후단부에 상기 회전커터부재에 근접하게 설치되어 회전커터부재와 연동하여 해양폐기물을 절단하도록 예리한 칼날 형태로 절단부가 형성되어 있는 고정커터부재;를 포함한다.
