A supporting device for crab harvesting and trapping

The device includes: a crab collection barrel, which is buried at the edge of a rice field, with the rim of its inlet flush with the ground; an escape-proof cover, fixed at the inlet of the crab collection barrel and provided with a through hole, in which a baffle plate is installed, with its discharge port extending into the crab collection barrel, the baffle plate being used to prevent crabs from climbing out of the barrel; a mesh bag, arranged between the crab collection barrel and the baffle plate and fixed to the escape-proof cover, the mesh bag being used to collect crabs; the baffle plate has a smooth surface, and there is a gap between the baffle plate and the mesh bag.

The gap, along with the smooth surface of the baffle plate, serves to block crabs attempting to climb out of the collection barrel, preventing them from escaping through the inlet. The present utility model can prevent crabs from escaping, thereby increasing the harvest yield per collection. Additionally, operators can directly transfer the mesh bag containing the collected crabs, making the collection method convenient, reducing collection time, and improving work efficiency.
