SCREED COMPACTION BEAM, SCREED, AND PAVER

摘要

A screed compaction beam comprising a drive shaft (1), a cam (2), a transmission rod (3), and a transmission rod resetting mechanism (5). The drive shaft (1) is connected to a drive motor. The cam (2) is sleeved onto the drive shaft (1) and is coaxially linked with the drive shaft (1). The upper end of the transmission rod (3) is contactedly connected to the outer peripheral wall of the cam (2), while the lower end is fixedly connected to a blade (6). The transmission rod resetting mechanism (5) allows the upper end of the transmission rod (3) to press tightly against the cam (2). Also provided are a screed provided with the screed compaction beam and a paver. The compaction beam is structurally simple and easy to remove.
