AUTOMATIC SURFACING APPARATUS FOR PURPLE LAVER CULTIVATION, CULTIVATION APPARATUS, AND AUTOMATIC SURFACING METHOD USING TIDAL RANGES

摘要

An automatic surfacing apparatus for purple laver cultivation comprises a hollow bearing rod (6) and a floating rod (8). One end of the hollow bearing rod (6) is perpendicularly and fixedly connected to a middle portion of the floating rod (8). Several tail wings (15) for stabilizing the hollow bearing rod (6) are evenly disposed at the other end of the hollow bearing rod (6) along a circumferential direction of a rod body. A big float (7) is sleeved over the hollow bearing rod (6) between the tail wings (15) and the floating rod (8). Oblique-pulling ropes (12) are disposed between the big float (7) and two ends of the floating rod (8). A surfacing root cable (10) that coordinates with the big float (7) to hold the floating rod (8) is threaded inside the hollow bearing rod (6) along an axial line of the rod body. In addition, the automatic surfacing apparatus for purple laver cultivation comprises or is applied to a full-floating purple laver cultivation apparatus of an automatic surfacing type using tidal ranges or a cultivation method of an automatic surfacing type using tidal ranges. By means of the automatic surfacing apparatus for purple laver cultivation, automatic surfacing and automatic sinking of a mesh screen can be implemented, labor intensity and cultivation costs are reduced, and the quality of purple laver is improved.
