Description

Mussel underwater automatic harvesting device and harvesting method thereof

technical field

The invention relates to a mussel underwater automatic harvesting device and a harvesting method thereof, belonging to the technical field of breeding engineering.

Background technique

Mussels are also called mussels, and the dried products are called mussels. They are bivalve molluscs with dark brown shells that live on seashore rocks. Distributed along the coasts of the Yellow Sea and the Bohai Sea in China. The mussel shell is wedge-shaped, with a tapered front end and a broad and round back end. Generally, the shell length is 6-8 cm, and the shell length is less than twice the shell height. The shell is thin. The top of the shell is near the front end of the shell. The two shells are equal, left and right symmetrical, the surface of the shell is purple-black, with luster, the growth lines are fine and obvious, and grow in a ring form from the top.

For example, an application number of CN105475244A discloses a non-destructive self-shedding mussel picking system, which aims to provide a method that can effectively solve the problem that the current mussel picking and harvesting method has a large damage to mussels, and may even cause mussel shells to rupture, mussels, etc. Non-destructive self-shedding mussel picking system for problems such as shell meat pressure loss. It includes a breeding rope, a frame and a self-falling removal device arranged on the frame; the farming rope includes a load-bearing core rope and several attachment ropes wound in parallel outside the load-bearing core rope; the self-falling removal device includes a load-bearing core rope. The first horizontal guide rail, the first sliding seat that can be slidably arranged on the first horizontal guide rail, the translation actuator used to drive the first sliding seat to move, the first clamping bracket arranged on the first sliding seat, set on The second horizontal guide rail on the frame and parallel to the first horizontal guide rail can slide the second sliding seat arranged on the second horizontal guide rail and the second clamping bracket arranged on the second sliding seat.

Because of their strong vitality, mussels are easy to cultivate in large quantities. Coastal provinces have vast sea areas for cultivation, and floating suspension cultivation systems are often used. Floating suspensions include cable buoys and high-density polyethylene pipes. At present, mussels are mostly harvested by small ships as vehicles, and mechanical lifting is used to drag the cultured rope ladder full of mussels from the sea to the harvesting slide, and then the mussels are threshed and cleaned by thresher and cleaning mechanism. In this way, because the hoisting process will lift the surrounding mussel chains, a lot of energy is consumed, and the harvesting time is long, the operation efficiency is low, and the stability of the floating hoisting system is affected. Therefore, how to develop a series of mechanical technology and equipment that can be applied to offshore operations according to the actual needs of mussel farming, harvesting and processing is to expand the scale of farming, shorten the harvest time, increase the proportion of fresh sales and labor costs for mussel production. An urgent need for productivity.
