The present invention relates to an automatic shellfish dredge for automatically gathering shellfish living in a wide expanse of mud flat deep in the sea without a need for employing divers, wherein seawater can flow naturally into an automatic dredge and suspended shellfish can be gathered promptly inside a fishing net (8), when a plurality of dredge members (6) turn the mud flat inside out with a boat towing the automatic dredge. According to the present invention, provided is the automatic shellfish dredge, wherein shellfishes (9) are collected and gathered into the fishing net (8), as a dredge member (6) fixed to an axis (4) turns the mud flat inside out by using the rotation of the axis (4) through a hydraulic motor (7) installed in a moving body (1). Therefore, the automatic shellfish dredge according to the present invention can be achieved in such a way that a seawater inlet (2) is formed to reduce tidal resistance on the front surface of the moving body (1) and promptly push the gathered shellfishes (9) into the fishing net (8) an iron net (3) is installed on the upper surface thereof to prevent the collected shellfishes (9) from escaping from the upper side thereof and a plurality of dredge members (6) bent in a shape of &Primeㄱ&Prime and consisting of a fixing portion (6a) and an edge portion (6b) are displaced cornerwise in the right and left sides to the axis (4), each of the dredge members (6) being located on the same line in an axial direction, thereby turning the mud flat (10) inside out in the moving direction of the moving body (1) and in the vertical direction thereof at the same time.COPYRIGHT KIPO 2017본 발명은 깊은 바다의 펄 속에 서식하는 패류를 잠수사를 고용하지 않고도 자동으로 채취하는 패류 자동채취기에 관한 것으로, 배가 자동채취기를 견인함에 있어 복수 개의 채취부재가 펄을 연속적으로 뒤집을 때 자동채취기의 내부로 해수가 자연스럽게 유입되도록 하여 채취되어 부상된 패류가 신속하게 어망에 수집되도록 한 것이다.본 발명은 이동체(1)에 설치된 유압모터(7)에 의한 축(4)의 회전으로 상기 축(4)에 고정된 채취부재(6)가 펄을 뒤집어 줌에 따라 패류(9)가 채취되어 어망(8)에 채집되는 패류 자동채취기에 있어서, 상기 이동체(1)의 전면에 조류 저항을 줄이고 채집된 패류(9)를 어망(8) 측으로 빠르게 밀어내도록
