| titleOfInvention | Device for drilling blastholes and breaking oversize lumps |
| abstract | Use: for drilling holes and destroying over-sized rocks without explosive energy. SUMMARY OF THE INVENTION: The supply and replacement of a drilling tool is carried out by a single drive; a feed hydraulic cylinder 2. For this, the device is equipped with a spring-loaded driver 15 and a rocker 14 mounted on the carriage 6, fingers and latches on the bracket and an emphasis 4 on the transverse element of the support frame. At the end of drilling, the carriage 6 with the informer is retracted by the hydraulic cylinder 2 until the stop 4 comes into contact with the rocker 14, which is pushed under the action of the stop, with the result that the bracket will be able to turn on the trunnions to replace the working position of the Executive Bodies. 5 il.
