APPARATUS AND METHOD FOR SECURING A SCREED PLATE

摘要

An apparatus and method for securing a screed plate (16) to a frame member (22) of a screed assembly (10) is disclosed. A leading edge portion (26) of the screed plate (16) is secured to the frame member (22) by a number of fastening assemblies (28) each of which includes an upper fastening block (36), a lower fastening block (38), and a bolt (40). The upper fastening block (36) is welded to the frame member (22), whereas the lower fastening block (38) is welded to the screed plate (16). Rotation of the bolt (40) causes the fastening blocks (36, 38), and hence the frame member (22) and the screed plate (16), to be secured to one another. The bolt (40) is disposed at an angle relative the screed plate (16) thereby allowing access thereto from a rear portion (52) of the screed assembly (10). Such a configuration allows the screed plate (16) to be exchanged without the need to remove the screed assembly (10) from the tractor associated with the paver. Such a configuration further allows the screed plate (16) to be exchanged without the need to remove a number of deflector plates (14) associated with the screed assembly (10).
