Silenced boom of excavator and excavator
The invention relates to excavators and booms thereof and discloses a silenced boom of an excavator. The silenced boom of the excavator is used for overcoming disadvantages of the existing excavators that special silencers are used. The silenced boom of the excavator comprises a box body structure with an internal cavity, wherein both the front end and the rear end of the box body structure are hinged ends; partition plates which are used for partitioning the internal cavity into a plurality of chambers, which at least comprise an air intake chamber, a resonant chamber and an exhaust chamber, are arranged in the box body structure; an air intake port communicating with the air intake chamber and an exhaust port communicating with the exhaust chamber are formed in the box body structure; resonance throat tubes are arranged on the partition plate between the air intake chamber and the resonant chamber, and an exhaust passage exists from the air intake chamber to the exhaust chamber. Meanwhile, the invention further discloses the excavator with the boom. The silenced boom has the advantages of low exhaust resistance, good silencing effect, whole-machine cost reduction and mounting space saving and meanwhile has the advantage that the structural strength of the boom is improved.
