Description

Technical Field

[0001] The utility model relates to the field of fences, in particular to a fence for crayfish breeding which can prevent crayfish from escaping. Background Art

[0002] Crayfish is a delicacy on our table. Nowadays, the market demand for crayfish is very large, so a large number of crayfish farms are needed to cultivate crayfish in order to meet the market demand and enable the breeders to obtain certain profits. The farms generally cultivate crayfish in a closed fence style, with the purpose of easy management and catching.

[0003] For example, a Chinese patent with announcement number CN218635058U discloses a crayfish breeding fence to prevent crayfish from escaping, including a fence and a fixing pin, wherein a middle rotating drum is arranged at the right end of the fence, and the middle rotating drum is fixedly connected to the fence, an outer rotating drum is arranged at the left end of the fence, and the outer rotating drum is fixedly connected to the fence, a plurality of ventilation holes are arranged at the upper part of the fence, a plurality of sealing grilles are arranged at the bottom of the fence, and the sealing grilles are fixedly connected to the fence, a fixing pin is rotatably connected inside the middle rotating drum, and a top cap is arranged on the top of the fixing pin. The top cap is fixedly connected to the fixing pin, a loading and unloading hole is provided on the side of the top cap, a spiral cone is provided at the bottom of the fixing pin, and the spiral cone is fixedly connected to the fixing pin. Although it solves the problem that "currently crayfish breeding fences are mainly made of woven nets, the fence effect is not good, and it cannot adapt to a variety of harsh environments. It is easy to cause holes in long-term use. If it is not replaced and repaired in time, the crayfish will drill out of the holes and escape, causing certain losses to the breeding." However, during use, there are cases where smaller crayfish escape through the sealing fence, which has certain management disadvantages.

[0004] For this reason, a crayfish breeding fence is proposed which prevents the crayfish from escaping. Utility Model Content
