[0002] In real life, coal strata often contain various different particle size coal blocks, rock fragments and silt and other materials. In the drilling process, these materials will be cut by the drill bit and enter the sampling bucket. Due to the different particle sizes and irregular shapes, the sampling bucket is easily accumulated and blocked. The coal geological exploration personnel usually use the drill to pull up and down the sampling bucket to relieve the blockage, which requires human power to adjust, not only consuming a lot of physical strength of the detection personnel, but also reducing the work efficiency.
