Grain husk cracking plate

摘要

A grain husk cracking plate for attaching to a chopping cylinder housing of a harvester in proximity to a shear bar to crack husks of grain moving through the harvester. The grain husk cracking plate includes a base plate adapted for directing grain through the chopping cylinder housing of the harvester. A pair of side mounting members are mounted to side edges of a base plate. A plurality of blade members are mounted on the top surface of the base plate. Each of the side mounting members has a pair of mounting structures, and each mounting structure comprises a mounting aperture extending through the side mounting member adjacent to the leading edge or the trailing edge of the base plate. Each of the mounting structures may include a threaded fastener coupled to each of the side mounting members. The plurality of blade members may be positioned on a rear portion of the base plate. Each of the blade members may comprise a blade assembly with a base member and an edge member, and the base member has a forward surface with the edge member mounted thereon. The forward surface of the base member may have a depression, with the edge member having a rear portion received in the depression of the base member. The edge member of each blade assembly may be formed of a material with relatively greater hardness than the base member. The edge member of each blade assembly may comprise a carbide material, and the base member of each blade assembly may comprise an iron material.
