Description

Technical Field

[0001] The utility model belongs to the technical field of prawn seedling breeding, and particularly relates to a prawn seedling collection device. Background Art

[0002] Prawn seedlings refer to individuals in the larval stage of prawns. This stage is the starting stage of the production cycle of cultured prawns. The quality of prawn seedlings directly affects the success rate and yield of aquaculture. The cultivation and management of prawn seedlings are important links in the aquaculture process. In the cultivation of prawn seedlings, a prawn seedling collection device is needed to collect prawn seedlings.

[0003] In the existing prawn seedling collection device, the wire rope of the prawn seedling collection net is controlled by controlling the operation of the winch to pay out the wire rope, so that the wire rope drives the prawn seedling collection net to sink into the storage pond. The prawn seedling collection net is driven by a drive module to move in the storage pond. When the prawn seedling collection net moves to a suitable position, the winch is controlled to take in the wire rope, so that the wire rope drives the prawn seedling collection net to rise, and the prawn seedlings in the storage pond are netted into the prawn seedling collection net. However, in the actual use process, since only one wire rope is used to control the rise of the prawn seedling collection net when collecting prawn seedlings, and during the process of collecting prawn seedlings, most of the prawn seedlings may not be located at the inner bottom end of the prawn seedling collection net. Therefore, during the rising process of the prawn seedling collection net, due to the weight of the prawn seedlings, the prawn seedling collection net may tilt to a certain extent, and then the opening above the prawn seedling collection net tilts, so that some prawn seedlings may fall out of the prawn seedling collection net and fall into the storage pond. The quality of the prawn seedlings falling out of the prawn seedling collection net may be problematic, affecting the subsequent breeding work. Summary of the Utility Model

[0004] In view of this, in order to overcome the deficiencies of the prior art, the utility model provides a prawn seedling collection device, which can stably pull the prawn seedling collection net to rise synchronously from the four corners by using nylon ropes, quickly and stably net out the prawn seedlings in the breeding pond, and can effectively avoid the prawn seedlings falling out of the prawn seedling collection net due to the tilt of the prawn seedling collection net during the upward pulling process.

[0005] To solve the above technical problems, the technical solution adopted by the present utility model is as follows: A prawn seedling collection device includes a bracket.
