Underwater quantitative larva throwing device

Abstract

The invention discloses an underwater quantitative larva throwing device which aims at completing quantitative throwing of underwater larvae and protecting the underwater larvae from being hurt. A steering shaft base is arranged on a linear guide rail through a sliding block. A gear is fixed to the lower end of a steering shaft, and a main cylinder is fixed to the upper end of the steering shaft. A rack is fixed to a rack supporting plate and meshed with the gear. A driving wheel and a driven wheel are arranged at the two ends of a base respectively. The driving wheel and the driven wheel are sleeved with a belt fixed to the steering shaft base. A piston is arranged in the main cylinder and driven by an electric push rod. A stop piece is arranged on the electric push rod. A separation net is arranged on the front portion of the main cylinder. An elastic sleeve is fixed to a sliding cylinder, and the main cylinder is sleeved with the elastic sleeve and the sliding cylinder together. The end A1 of a crank A1B1 and the end A2 of a crank A2B2 are arranged on the outer side wall of the main cylinder through hinges, three rods at the end B1 and three rods at the end B2 are connected through hinges respectively. The end C1 of a connecting rod B1C1 and the end C2 of a connecting rod B2C2 are arranged on the outer side wall of the sliding cylinder through hinges, two connecting rods at the end D are connected through a hinge. The hinge joint of the end A1 and the end A2 is sleeved with a reset spring. The underwater quantitative larva throwing device can complete quantitative larva throwing and protect the larvae from being hurt.

Description

technical field [0001] The invention relates to a seedling throwing device, in particular to an underwater quantitative seedling throwing device. Background technique [0002] In the cultivation of aquatic products, especially the cultivation of sea cucumbers and abalones, seedlings need to be placed on designated artificial reefs. At present, the work of throwing seedlings is mainly done by professional divers. They dive into the water with gauze bags full of seedlings on their backs, find artificial reefs, drop a certain amount of seedlings, and then continue to the next place for seedling throwing until the entire cultivation is completed. The whole process of throwing seedlings in the region requires a lot of human and financial resources. For larger breeding areas such as marine ranches, tens of thousands or even hundreds of thousands of catties of seedlings need to be put in, and it is time-consuming and labor-intensive to rely on people alone. At the same time, due ...

Problems solved by technology

At present, the work of throwing seedlings is mainly done by professional divers. They dive into the water with gauze bags full of seedlings on their backs, find artificial reefs, drop a certain amount of seedlings, and then continue to the next place for seedling throwing until the entire cultivation is completed. The seedling work in the region requires a lot of manpower and financial resources in the whole process

For larger breeding areas such as ocean ranches, tens of thousands of catties or even hundreds of thousands of catties of seedlings need to be put in, and it is time-consuming and labor-intensive to rely on people alone

At the same time, due to the particularity of the work of this kind of divers, they work in an inverted state underwater, which has certain damage to the human body. Therefore, fewer and fewer people are engaged in this work, and there may be a labor shortage in the future. Putting in seedlings in product breeding is an urgent problem to be solved

[0003] With the development of science and technology, the research and development and application of underwater robots have made great progress, but they can only complete underwater monitoring and simple underwater grasping, etc. At present, there is no one that can be used on underwater robots.
