| description | The utility model relates to the technical field of blasting engineering, in particular to a recyclable solid carbon dioxide pneumatic rock breaking device, which is characterized in that a shell of the device is formed by connecting three sections of cylinders, the bottom end of the lower section of cylinder is welded with a bottom cover for sealing, the outer side of the middle section of cylinder is uniformly provided with a plurality of thin grooves, and the top of the upper section of cylinder is connected with a sealing top cover. The shell, the bottom cover and the top cover form a closed pressure container, a heating device and an excitation device are preset in the center of the pressure container, and the rest space is filled with solid carbon dioxide. According to the utility model, solid carbon dioxide is used as a carrier, and after each time of use, only the middle section of cylinder is damaged, the lower section of cylinder and the upper section of cylinder can be recycled and reused, so that |
