The present invention relates to a laver unloading device. A plurality of pillars are installed at particular intervals on both left and right sides in a laver extracting chamber which is installed in a ship for extracting laver adhered on a laver screen. A plurality of left and right guiderails are installed in parallel with each other toward the left and right sides of the ship while both ends thereof are fixed to the top end of a top divided pillar of every two pillars that face each other while being separately installed on the left and right sides of the ship at a predetermined interval. A left and right moving device is mounted on both ends of the laver unloading device to be moved in the left and right directions of the ship along the left and right guiderails. A plurality of front and rear guiderails are installed in parallel with each other toward the back and front of the ship. The front and rear guiderails include a front and rear moving device installed to reciprocate in the front and rear directions of the ship. An elevating cylinder is formed in the front and rear moving device to make a piston rod protrude downward from the front and rear moving device while a cylinder body is fixed to vertically protrude on the top surface of the front and rear moving device. A bucket elevating device is connected with a fixing connector fixed and installed on the bottom surface of the front and rear moving device so as to move a bucket for unloading laver up and down by means of the protrusion of the piston rod of the elevating cylinder.COPYRIGHT KIPO 2014본 발명은 김 하역장치에 관한 것으로, 김발에 붙어있는 김을 채취하는 배에 설치되어 있는 김채취실의 좌,우 양측 각각에는 일정 간격을 유지하도록 복수개씩 형성되는 기둥이 설치되어 있으며, 상기 복수의 기둥들 중 배의 좌,우측 각각에 일정 간격으로 이격 설치된 채 서로 마주하는 2개씩의 기둥 각각의 상부 분할기둥 상단에 양단이 고정된 채 배의 좌,우측을 향해 서로 평행하도록 설치되는 복수의 좌우안내레일이 형성되어 있으며, 상기 복수의 좌우안내레일을 따라 배의 좌우 방향을 향해 이동가능하도록 설치되는 좌우이동장치가 양단에 장착되어 있고 배의 전후 방향을 향해 서로 평행하도록 설치되는 복수의 전후안내레일이 형성되어 있으며, 상기 복수의 전후안내레일에는 배의 전후 방향으로 왕복이동이 가능하도록 설치되는 전후이동장치가 형성되어 있으며, 상기 전후이
