Capture device for farming crayfish in rice field in south China

Abstract

The invention relates to the technical field of crayfish farming and discloses a capture device for farming crayfish in a rice field in the south China. The capture device comprises a transfer mechanism and a capture mechanism, wherein the transfer mechanism comprises a base; the upper end of the base is fixedly connected with a fixed box; two through holes are symmetrically formed in the upper end of the fixed box; the inside of each through hole is rotationally connected with a rotating screw through a ball bearing; the upper end of each rotating screw is in threaded connection with a lifting screw cylinder; and the upper ends of two lifting screw cylinders are fixedly connected with a same support frame. The capture device for farming the crayfish in the rice field in the south China has the advantages that the capture device can quickly capture the crayfish and is suitable for the position, which is difficult to capture, namely the rice field for capturing the crayfish.

Description

technical field [0001] The invention relates to the technical field of crayfish farming, in particular to a catching device for cultivating crayfish in paddy fields in southern regions.
