The utility model relates to a diamond-based composite picking head in which a picking head is embedded in a head of a cemented carbide substrate, and a surface of the cemented carbide body portion is exposed on the surface of the picking head to be coated with a diamond composite material. Therefore, the preparation operation is simple, the application range is wide, and the wear resistance is improved by 3000 times and the impact resistance is correspondingly improved as compared with the ordinary hard alloy. When applied to the roadheader, the tunneling speed can be increased by more than 30%, the service life is greatly extended, and the tunneling cost is reduced by about 35%.
