| titleOfInvention | Novel blasting cartridge |
| abstract | The utility model discloses a novel blast pipe, including body and disappointing head, body and disappointing head are hollow structure, the one end of body with open and explode the device and be connected, fill liquid carbon dioxide in the hollow structure of body, the other end of body is equipped with the linkage segment, the linkage segment is connected with disappointing head, it is sealed through the voltage limiting piece between linkage segment and the disappointing head, the one end that the body is close to the linkage segment is equipped with the chamfer, the chamfer is 42-47, the external diameter of the head of letting out is the same with the external diameter of body, perhaps, the external diameter of the head of letting out is 2-3cm bigger than the external diameter of body. Has the advantages that: change the traditional connected mode that loses heart head insert the body, insert the body through the linkage segment with the body and let out in the gas head, the chamfer is seted up to the body simultaneously, makes the body and form annular groove between the head that loses heart, and during the blasting, the slay is piled up and is filled in annular groove, increases the resistance between blasting tube and the blasting pore wall, prevents that the blasting tube from the downthehole departure of blasting, increases blasting security. |
