The invention provides an energy-saving bundled combined hammer which comprises a square connecting head, a main air inlet pipe, an air inlet chamber, an air dividing pipe, a main exhaust pipe, an exhaust chamber, connectors, an exhaust pipe branch, a barrel and an impactor. The square connecting head, the air inlet chamber, the exhaust chamber and the barrel are sequentially fixed from top to bottom. The connectors are arranged at the top of the barrel and the side face of the exhaust chamber, and the impactor is mounted at the bottom of the barrel. The square connecting head is communicated with the air inlet chamber through the main air inlet pipe, the air inlet chamber is communicated with the connectors through the air dividing pipe, and the connectors are communicated with the impactor. The impactor is further communicated with the exhaust chamber through the exhaust pipe branch, and the main exhaust pipe is arranged on the exhaust chamber. Blast consumption is reduced, and under the same condition, at least two fifths of blast volume is saved. The pore forming efficiency is high, pore bottom back pressure is small, and therefore the problem that due to too large treatment back pressure, work efficiency is low is avoided. Comprehensive cost is low, and the manual labor intensity is lowered.
