Development of TGQ Knapsack Sampling Drill

Abstract:

Sampling is required anywhere at anytime in the geologic survey and reconnaissance stage, it is necessary to develop portable sampling drill with the characteristics of convenient relocation, high efficiency and high quality. This paper introduces TGQ knapsack sampling drill about its parameters, features and the related tests. With the characteristics of small size, light weight, high and low gear speeds by reasonable structure design, the rig can realize diamond drilling and auger boring, take core in inclined hole and take sample in complex stratum. The drilling tools are made of high strength materials and rapid plug-in type connecting structure is used on drilling rod, the efficiency of drill pipe screwing on and off is improved. The development of this drilling rig has broken the monopoly of foreign products in Chinese market.
