Charge

Abstract

A charge comprises a case, the bottom of which has disposed therein an explosive cartridge, on the inside surface of which cartridge there is mounted a liner. Opposite the bottom, an upper portion of the case is cylindrical and threaded and is provided with a threaded bushing, which is mounted such as to abut the liner and has a through aperture with a diameter that is less than the inside diameter of the liner. The threaded sleeve has an internal or an external thread and the upper portion of the case has an external or an internal thread accordingly. The threaded sleeve has recesses about its periphery for the installation of a removable turning means. The bottom and the outside surface of the cartridge are conical. The liner is configured with a cylindrical shoulder in its upper part and has a height which is greater than that of the cartridge.

What is claimed is: 
     
         1 . A charge containing a case, in a tapering bottom of which an explosive cartridge is placed, a cavity is mounted on an inner surface of the cartridge, and an upper part opposite to the bottom is made cylindrical with a threaded bushing, characterized in that the threaded bushing is made with grooves along a periphery to install a detachable tool of rotation and with a through hole having a diameter smaller than an internal diameter of the cavity, and installed until tight to the cavity. 
     
     
         2 . The charge according to  claim 1 , characterized in that the upper part of the case is made with an external thread, and the thrust threaded bushing is made with an internal thread and with grooves in a form of blind pin-mounting holes for the detachable tool of rotation. 
     
     
         3 . The charge according to  claim 1 , characterized in that the upper part of the case is made with an internal thread, and the thrust threaded bushing is made with an external thread and with grooves in a form of radial slots for shoulders of the detachable tool of rotation. 
     
     
         4 . The charge according to  claim 1  claim, characterized in that the case is made to be fixed mounted. 
     
     
         5 . The charge according to  claim 1 , characterized in that a thread connection of the threaded bushing with the upper part of the case is fixed against self-unscrewing. 
     
     
         6 . The charge according to  claim 1 , characterized in that the bottom of the case and an outer surface of the cartridge are made conical. 
     
     
         7 . The charge according to  claim 1 , characterized in that the cartridge is made hollow with a conical internal surface. 
     
     
         8 . The charge according to  claim 1 , characterized in that the cavity is made with a cylindrical band in the upper part and higher than the explosive cartridge.
