Fuente: WIPO "industrial hemp" The utility model relates to the technical field of industrial hemp breeding equipment, and provides a combined isolating device for industrial hemp breeding, which aims to solve the problems that the existing industrial hemp is easy to mix during breeding, and the existing isolating device is poor in adaptability, wind-proof and overturn-proof effects and poor in stability, and comprises a plurality of fixing nails, the upper ends of the multiple fixing nails are vertically and fixedly connected with mounting pipes with the upper ends not closed, mounting columns are vertically inserted into inner cavities of the mounting pipes, positioning holes are formed in the top walls of the mounting columns, flange bolts are in threaded connection with the interiors of the positioning holes, and anti-skid gaskets are laid at the lower ends of flanges of the flange bolts. A plurality of anti-disengaging clamping grooves are formed in the annular side wall, corresponding to the position of an inner cavity of the mounting pipe, of the mounting column, anti-disengaging clamping springs are connected into the anti-disengaging clamping grooves in a sliding mode, and the anti-disengaging clamping springs are fixedly mounted on the annular inner wall of the mounting pipe. The industrial hemp breeding isolation device is particularly suitable for industrial hemp breeding isolation and has high social use value and application prospects.
