【Abstract】 The portable sampler is used in soil investigation. It is made of a frame of aluminum alloy, a spiral anchorage block, an upset by chain driver, and a turn by bevel gear, etc. The totally enclosed sample barrel is designed to turn on and off in self action. When the barrel is forced into the position of the soil sampling and when you rotate it clockwise, it opens to collect the samples. To avoid losing or polluting the samples, it is closed by counter clockwise rotation. This sampler is light to carry about and can be run easily. It needs only one person to operate it.更多还原
