<p>PROBLEM TO BE SOLVED: To provide an explosive charging device that can achieve a cost reduction through the simplification of the device, shorten time required to switch from work for drilling a blast hole to charging work, and charge explosives into a specified position of the blast hole smoothly and reliably.SOLUTION: A work machine 1 comprises a drilling device 6 and a device body 11 of an explosive charging device 10 that are mounted at the tip of a boom 3 that can move up and down. In the explosive charging device 10, an explosive cartridge C is attached to a cartridge attachment 12 on the front end surface of the device body 11. In the device body 11, there is provided a push rod feeding mechanism 13 for axially pushing and pulling a long push rod 14 that can insert the explosive cartridge C into the blast hole. Further, the explosive charging device 10 has a switching mechanism 16 for alternately switching the position of the axial line of the drilling device 6 and that of the device body 11 while maintaining a parallelism between the axial line of the drilling device 6 and the axial line of the device body 11.</p> |
