Overall-sampling device for sectional rock stratums of biological fossils

Abstract

The invention discloses an overall-sampling device for sectional rock stratums of biological fossils. A drilling mechanism is arranged to comprise an outer drill barrel, an inner drill barrel, an outer drill barrel drive motor and an inner drill barrel drive motor; drilling edges are arranged at the front ends of the outer drill barrel and the inner drill barrel; the drilling edge of the outer drill barrel is shorter than the drilling edge of the inner drill barrel, so that the drilling edge of the inner drill barrel is forwards protruded out of the drilling edge of the outer drill barrel; when drilling a slot hole, the inner drill barrel can firstly drill, and the outer drill barrel is then adopted for chambering, so that the vibration during drilling is reduced, the fossils are preventedfrom being cracked; and a buffer mechanism is further arranged, so that the vibration generated by drilling can be further reduced through a buffer effect of the buffer mechanism, and the fossils areprevented from being damaged.

Description

technical field [0001] Specifically, the invention relates to an integral sampling device for section rock formations used for biological fossils, and relates to the related field of fossil sampling equipment. Background technique [0002] At present, after fossils are discovered, especially in the field, rocks, caves, etc., after the discovery of fossils, it is generally necessary to sample them. The current sampling method is generally to destroy the rocks around the fossils, and then the fossils Just cut it off. Although this method is simple, it will cause great damage to the surrounding rocks and affect the research of the surrounding rocks. At the same time, due to the destruction of the surrounding rocks and cutting, it is easy to cause cracks, Problems such as cracks will cause damage to the fossils, affecting the sampling effect and sampling ability. Contents of the invention [0003] Therefore, in order to solve the above-mentioned disadvantages, the present inv...
