英国阿伯丁大学工程系和冲积层采掘公司合作研制出一种新式取芯机具。它有一个转换部件联结到传统的振动取芯机上,从而既可以产生振动,也可以产生冲击,能够在多种类型的土壤中取得良好的穿入效果。这种振动冲击取芯机能够自身调整,在松散的非
University of Aberdeen Engineering and alluvial mining company to develop a new type of coring machinery. It has a conversion unit coupled to a conventional vibrating coring machine to generate vibrations and shocks and to achieve good penetration in many types of soils. This kind of vibrating impact coring machine can adjust itself in a loose way
