Bidirectionally freely rotating pedestal of rock core drilling machine and sampling method

The invention provides a bidirectionally freely rotating pedestal of a rock core drilling machine and a sampling method. The bidirectionally freely rotating pedestal comprises a rotary rock sample tray structure, a spherical hinge support structure, a movable chassis structure and a base plate structure. The pedestal is simple to manufacture, high in precision, safe, environment friendly, and convenient and reliable to operate. According to the invention, the rock sample tray of a sample drilling machine is improved and is allowed to be able to incline so as to facilitate selection of a desired bedding rock sample drilling angel and drilling of rock samples with different bedding inclination angles; moreover, the pedestal is movable, so the positions of rock samples can be conveniently adjusted. 本发明提供了种双向自由旋转岩石取芯机底座及取样方法，它包括旋转岩样托盘结构、球铰支座结构、活动底盘结构和底板结构。其制造简单，精度高，安全环保，操作起来方便可靠。本发明对钻样机的岩样托盘进行了改进，使钻样机的岩样托盘可以倾斜，以便于选择需要的层理岩样钻进角度，钻取不同层理倾角的岩样。同时也可以移动，方便调整岩样的位置。
