摘要: The asphalt tamper includes a tamper plate connected to a reciprocating rod that oscillates inside of a protective sleeve, wherein the reciprocating rod abuts a cam that rotates about the output of a motor. The reciprocating rod has a shoulder that interacts with a spring that applies a biasing force ushering the reciprocating rod back and forth upon interaction with the rotating cam.
