The development of industrial economy brings convenience and material enjoyment to people’s life， but it also inevitably brings some environmental problems， such as pollution of soil， water and air； hence， harm to people’s life and survival. In order to sample and measure the pollution degree of soil and provide scientific basis for later treatment， ESD-70 environmental protection sampling drill is developed to integrate sampling and treatment. The rig is designed with the hydraulic cylinder for feed and lift， which is more stable than the traditional chain； It can drill at multiple angles， and equipped with the open and close control cabinet， and wireless remote control and electro-hydraulic control. It is compact， rubber crawler-mounted and with strong impact force of the power head， which can meet the needs of soil sampling up to the depth of 0~30m. The drill operates on a direct push sampling way with a double-tube sampler， and the samples directly reach the inner tube to effectively maintain the original state of the soil. The drill can also be used for simple jet treatment of soil； thus achieving use for multiple purposes. Moreover， the drill has the advantages of simple operation， high safety， stable performance and high efficiency， which can greatly reduce the labor intensity of soil sampling personnel.
