Description

Technical Field

[0001] The invention relates to the technical field of breeding, and in particular to an escape-prevention device for breeding turtles in rice fields. Background Art

[0002] Raising turtles in rice fields is a method of breeding that combines rice planting with turtle farming. In this breeding method, turtles can move freely in the rice fields, prey on pests, loosen the soil, and their excrement can provide nutrients for the rice. At the same time, the rice also provides shade and a habitat for the turtles.

[0003] When raising turtles in rice fields, it is necessary to use corresponding anti-escape devices to prevent the turtles from escaping from the rice fields. A patent document with an existing application number of 2024107316102 and a publication date of 20240806 discloses an anti-escape device for rice field farmed turtles, including a mounting frame, a blocking mechanism for blocking farmed turtles on the mounting frame, and an anti-bite mechanism for preventing farmed turtles from biting. The present invention uses a protective net wound on the outside of a net roller, a first rotating roller and a second rotating roller to enclose the rice field, so that the turtles cannot escape, and the driving component drives the flapping mechanism to flap the lower side of the protective net to prevent the turtles from biting the protective net. In addition, the arc-shaped rod drives the pushing roller to push the middle part of the protective net outward, so that the lower part of the protective net forms an inclined surface that gradually extends outward from the bottom to the top, thereby making it difficult for the turtles to climb up along the protective net. The present invention uses a buffer component to buffer the fallen turtles, prevent the fallen turtles from directly contacting the bottom surface and causing falls, and further protect the turtles.

[0004] Although the anti-escape device can block farmed turtles in rice fields and prevent them from escaping from the rice fields, it can only protect a certain range of rice fields during application and cannot be adaptively adjusted according to the complex terrain of the rice fields. The application range is relatively small. For this reason, we propose an anti-escape device for raising turtles in rice fields. Summary of the invention
