Convenient nest casting equipment for aquaculture

Abstract

The invention discloses convenient nest casting equipment for aquaculture. The equipment comprises two rotary mechanisms, the rotary mechanisms comprise fixing plates, rotary columns, nuts, first telescopic columns, supporting rods and baffle blocks, two rotary columns are symmetrically arranged on both left and right sides of each of the fixing plates, the two connecting columns are connected through a second telescopic column, the bottom face of the fixing plate located below is connected with fixing columns, the rotary columns are fixed to the fixing plates through the nuts, the rotary columns are connected with one end of the first telescopic columns, the other end of the first telescopic columns are fixedly connected with the baffle blocks, the side faces of the first telescopic columns are movably sleeved with pull rings on a fish net, the pull rings at the two ends of the fish net are fixed to the two baffle blocks respectively, the pull rings in the middle of the fish net are fixed to the supporting rods, and the supporting rods are fixed to the front end faces of the fixing plates. By means of the equipment, the casting and recovering of the fish net are convenient, the equipment is more conformed to actual situations, and the adaptability is high.

Description

technical field [0001] The invention relates to the technical field of aquaculture equipment, in particular to a convenient net-casting equipment for aquaculture. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. [0003] Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish farming, cag...

AI Technical Summary

Problems solved by technology

[0004] Fish or shrimp are the main crops of aquaculture. When they grow long, they are usually caught by fishing nets. It is very inconvenient to open with the help of bamboo poles, so we propose a convenient net-casting device in aquaculture to solve the above problems
