Description

Technical Field

[0001] The utility model belongs to the technical field of rice-shrimp breeding, and specifically relates to a rice field crayfish breeding feeding net. Background Art

[0002] There is abundant water in the south, so the main grain is rice. In order to increase agricultural income and make more rational use of resources, in addition to growing rice, various ecological breeding is often carried out in rice fields, such as various aquatic products and crops. Among them, shrimp and crab farming in rice fields is the most common. Since shrimp and crab farming in natural conditions have higher value, farmers often adopt a method of simulating natural ecology to raise lobsters, and feeding net farming is one of them.

[0003] After searching, the Chinese utility model patent with announcement number CN220044578U discloses a rice field crayfish breeding feeding net, comprising four discs, a plurality of plug-ins are fixedly installed on the lower ends of the discs, a sleeve column is fixedly installed on the upper ends of the discs, and a pillar is penetrated through the upper ends of the sleeve columns, a metal fine mesh plate 1 is fixedly installed on the tops of the four pillars, a U-shaped plate is fixedly installed on the front and rear ends of the metal fine mesh plate 1, a metal fine mesh plate 2 is fixedly installed on the inside of the U-shaped plate near the top of the metal fine mesh plate 1, a blocking net is arranged inside the U-shaped plate, a return frame is fixedly installed on the outside of the blocking net, two hooks are fixedly installed on the inner walls on both sides of the U-shaped plate, and the two hooks are vertically equidistantly arranged; the rice field crayfish breeding feeding net described in the utility model improves the stability of the feeding net and is convenient for feeding.

[0004] In the above scheme, when catching crayfish, although the return frames on both sides can prevent the crayfish from escaping from both sides of the U-shaped plate, there is a lack of interception mechanism at both ends of the U-shaped plate, resulting in the crayfish still escaping from both ends of the U-shaped plate. In addition, manual feeding is required during feeding, which is labor-intensive, inefficient, and easily causes uneven feeding.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies.
