Abstract

The invention discloses a shellfish throwing device and method. The device comprises a circular storage tank with the upper end open and arranged on a ship, an agitator arranged in the circular storage tank, a plurality of throwing pipes connected to the bottom of the circular storage tank, a telescopic pipe disposed on the lower portion of each throwing pipe, a roller disposed at the lower end ofeach telescopic pipe and a rotating disc disposed on each throwing pipe below the water surface. An elastic baffle is disposed in each throwing pipe above the corresponding rotating disc, the throwing pipes above the elastic baffles are provided with a plurality of openings, and an annular groove is formed in the outer side wall of each rotating disc. Each annular groove is provided with a winding rope. The free end of each rope is connected with a rotating shaft of the corresponding roller, and the upper surface of each rotating disc is provided with a flexible backing plate. The device hasthe advantages of good safety in the throwing process, high throwing efficiency and high survival rate.

Description

technical field [0001] The invention relates to the technical field of marine organisms, in particular to a device and method for expelling shellfish that can adjust the distribution density of shellfish according to water depth. Background technique [0002] Marine ecological restoration is a complicated process. Shellfish obtain food by filtering seawater through the digestive system, which can effectively filter oxides and algae, have good filtration and enrichment characteristics, and can absorb and consume various toxic substances such as benzene and phenol. Excess organic matter in seawater plays a role in purifying seawater. Shellfish can provide ecological services and are known as ecological cleaners, which can filter out sediment in the water, improve water quality, and make the water clearer. What's more, they can remove toxic substances from water. [0003] At present, the eutrophication in China's coastal waters is serious, and there is an urgent need to impro...
