Insert rod for sea area aquaculture

Abstract

An insert rod for sea area aquaculture comprises a tubular plastic rod body, a drill bit is connected at the lower end of the rod body and comprises a screw-in portion and an inverted-cone-shaped pointed end portion, the screw-in portion comprises a column, the outer surface of the column is provided with projections in thread-shaped distribution, the column is connected with the lower end of the rod body, and the bottom surface of the pointed end portion is connected with the column. The insert rod for sea area aquaculture, made of plastics, is lightweight, high in bending strength and corrosion resistance, long in service life, cheap, reusable, free of pollution, convenient and labor saving to mount and arrange and saving in labor, time and expense.

Description

technical field [0001] The invention relates to the field of marine aquaculture, in particular to a cutting rod for marine aquaculture. Background technique [0002] Seaweed cultivation has become more and more widespread nowadays. For example, altar laver cultivation has been widely carried out along the coast of Zhejiang. Altar laver cultivation is a sunrise industry with low investment and obvious economic and social benefits. The most important method is that the net curtain is hung on the insertion rod deep in the sea area through the buoy, and the net curtain can be raised and lowered with the tide or artificial control. The plunger is the core part of the plunger-type raft, and its function is to support the entire raft. The quality of the insert rods determines the breeding effect. [0003] At present, the bamboo poles of large-scale moso bamboo are generally used as the stems. The average annual investment of farmers on the stems of moso bamboo accounts for more t...

AI Technical Summary

Problems solved by technology

[0004] 1. Perishable, short service life

2. The length of moso bamboo itself is limited, generally no more than 16 meters, which restricts stocking in deeper sea areas

3. Moso bamboo is thick and heavy, and the labor intensity required for processing, transporting and inserting it into the mud is very high

4. Cause environmental damage

5. Waste moso bamboo sticks cannot be reused

But these two kinds of plunger prices are high, and the cost is large, almost ten times that of the original moso bamboo, which is not conducive to market promotion

[0006] In short, there is no suitable and economical cutting rod that can meet the needs of altar laver culture or other similar sea area culture.
