Long-line culture mechanical harvesting shellfish culture cage, harvesting equipment and working method

Abstract

The invention relates to a mechanical shellfish harvesting culture cage for longline culture. The mechanical shellfish harvesting culture cage comprises a box body, side plates and locking arms, a plurality of hanging rings are arranged on the central axis of the upper end face of the box body. The front side surface of the box body is open, the upper part of the front side surface is provided with a group of hinges I, and the side plate is hung on the box body through the first group of hinges and covers the front side surface; a pair of hinges II is arranged at the front parts of the left and right sides of the bottom of the box body; the locking arm is in a frame shape, the left side edge and the right side edge of the locking arm are hinged to the second hinge, and the front portion of the locking arm is bent upwards to buckle the lower portion of the side plate so that the side plate can seal the box body. Ejector rods extend out of the set height positions on the rear side face of the box body in the left-right direction respectively, the locking arms are lifted upwards to make contact with the ejector rods and then continue to be lifted, the box body can be driven to rotate with the hanging ring as the fulcrum, and the dumping action is carried out. By means of the shellfish culture cage collecting device, cage lifting, cage opening and cage discharging operations, which consume the largest manpower, of traditional shellfish culture cages can be completely replaced by mechanical operations, and the labor intensity of the operations is greatly reduced.
