摘要(英):
The invention discloses a carbon dioxide blaster. The carbon dioxide blaster comprises a push rod, a liquid storage pipe and an exhaust pipe, wherein the liquid storage pipe is internally provided with a liquid storage cavity; the exhaust pipe is internally provided with an exhaust cavity; exhaust holes are formed in the surface of the exhaust pipe and are communicated with the exhaust cavity; the push rod is connected with the liquid storage pipe by a first connector; the liquid storage pipe is connected with the exhaust pipe by a second connector; the first connector is provided with a heater; the second connector is provided with a constant pressure shear piece; the constant pressure shear piece is arranged between the liquid storage cavity and the exhaust cavity. The carbon dioxide blaster can avoid the conditions that the push rod is separated and ejected from a drill hole as well as is damaged and deforms, and facilitates recycling of a blast tube. 1.一种二氧化碳爆破器,其特征在于,包括推送杆(1)、储液管(2)和排气管(3),所述储液管(2)内设有储液腔(21),排气管(3)内设有排气腔(31),排气管(3)表面设有排气孔(32),排气孔(32)与排气腔(31)连通,所述推送杆(1)与储液管(2)间通过一连接头(4)相连,储液管(2)与排气管(3)间通过二连接头(5)相连,一接头上设置加热器(41),二连接头(5)上设置定压剪切片(51),定压剪切片(51)设置在储液腔(21)与排气腔(31)之间。
