[0013] Compared with related technologies, the rapid positioning and quantitative charging device for blasting holes in open-pit mines provided by this utility model has the following advantages:

[0014] This utility model provides a rapid positioning and quantitative charging device for blasting holes in open-pit mines. By connecting a spring, a T-shaped slider is elastically pushed until its outer side is tightly fitted or inserted into the inner wall of the charging hole. This effectively reduces the occurrence of positional deviation when the quantitative charging shell is disturbed by external forces, and enhances the stability of the quantitative charging shell in the designated position. At the same time, the oblique movement of the T-shaped slider and its fit with the inner side of the charging hole can increase the load-bearing capacity of the quantitative charging shell, which is beneficial to improving the applicability of the equipment.
