Zusammenfassung:	The utility model discloses a silencer of a pneumatic anchor rod drilling machine. The silencer comprises a silencing sleeve and a silencing rod. The silencer comprises a top wall and a tubular side wall fixedly connected with the top wall, and a plurality of small holes b are formed in the top wall. The silencing rod comprises a silencing part, a circular connecting part a and a circular connecting part b which are sequentially connected. The silencing part comprises a top wall and a tubular side wall fixedly connected with the top wall, a plurality of small holes a are formed in the side wall of the silencing part, and the silencing part is placed in a cavity of the silencing sleeve. The connecting part a is connected with the silencing sleeve, and the diameter of the connecting part a is larger than the diameter of the silencing part. According to the silencer of the pneumatic anchor rod drilling machine, the noise of a downhole drilling site is lowered within the range capable of being accepted by workers
