The invention discloses a spark-proof excavator silencer, which relates to the technical field of silencers, and comprises an outer pipe and a liner pipe, two ports of the outer pipe are smooth, a flow dividing cover is installed on the inner side of one end of the outer pipe, an inclined flow guiding pipe is arranged in the middle of the flow dividing cover, and a friction pipe is fixed to the outer side of the flow guiding pipe. The end, close to the flow dividing cover, of the lining pipe is shrunk to form a shrunk part, the end of the shrunk part extends into the friction pipe, an annular isolation plate is fixed to the outer side face of the shrunk part and divides a gap between the outer pipe and the lining pipe into two cavities, an annular cavity is formed between the isolation plate and the friction pipe, and connecting holes are distributed in the side face of the shrunk part; the silencer further comprises a silencing pipe, the lining pipe is sleeved with the silencing pipe, and a cavity where the silencing pipe is located is communicated with an inner cavity of the lining pipe through a connecting hole. The sparkproof excavator silencer has good silencing capacity, meanwhile, sparks are prevented from overflowing, and good safety is achieved.
本发明公开了一种防火星挖掘机消音器，涉及消音器技术领域，包括外管和衬管；外管：两个端口畅通，其中一端内侧安装有分流罩，所述分流罩的中部设有斜向的导流管，所述导流管的外侧固定有摩擦管；衬管：靠近分流罩的一端收缩形成收缩部，且收缩部的端头延伸至摩擦管内，所述收缩部的外侧面固定有环形的隔离板，隔离板将外管和衬管的间隙分割成两个腔室，所述隔离板和摩擦管之间为环腔，所述收缩部的侧面分布有连接孔；还包括消音管，所述消音管套在衬管的外侧，所述消音管所处的腔室与衬管的内腔通过连接孔相通。本防火星挖掘机消音器，具有良好的消音能力，同时避免火星外溢，具有良好的安全性。
