摘要： A boring bit or other component for horizontal directional drilling is provided which includes a hard faced layer that is preferably made by a laser cladding bead. A subsequent or post heat treatment is applied to modify the heat affected zone (HAZ) to eliminate or reduce the hard brittle regions and/or softer regions in the base iron or steel material of the HAZ. Further, the hard faced layer may be applied in combination with carbide insert teeth that are embedded within the steel base of the boring bit body, such as by press fitting.

摘要： A boring bit such as for horizontal directional drilling is provided which includes a hard faced layer that is preferably made by a laser cladding bead. The laser clad bead may be applied in some regions to a greater extent and in other regions to a lighter extent and with thicker coverage or longer regions of application in different regions of the boring bit. Additionally, circumferential segments of the hard faced layer bead may be applied to impart a spiral path on the outer periphery of the boring bit which may be overlapped upon more general hard faced layer application. Further, the hard faced layer may be applied in substantially complete coverage over carbide insert teeth that are embedded within the steel base of the boring bit body.

摘要： The concave section includes a first concave body. The first concave body includes a first leading end, a first trailing end, a first upstream side and a first downstream side. A width between the first upstream side and the first downstream side is no greater than 10 inches. The first concave body includes a first crop engagement face that extends between the first ends and the first sides. The first crop engagement face includes at least one of a first thresher profile portion and a first separator profile portion.

摘要： A sickle cutting section is provided. The sickle cutting section comprises a plate having a base material of a first hardness. The plate extends forwardly from a mounting portion to a front tip. A serrated cutting edge extends at least partially between the front tip and the mounting portion. A clad material is of a second hardness that is harder than the first hardness and is deposited along the base material at least partially along the serrated cutting edge.

摘要： A crop harvesting header with a cutter bar and a draper assembly has a draper canvas driven by a drive roller with a cylindrical roller body having an outer surface surrounding an axis of rotation of the roller for engaging an inner drive surface of a canvas wrapped therearound. The roller has a plurality of ribs arranged on the outer surface of the roller body extending along a part of the body in an axial direction and angularly spaced around the outer surface. The ribs have a height less than 6 mm and a width less than 6 mm arranged such that the ribs do not engage into any recesses in the drive surface of the canvas.

摘要： A concave section for a harvester includes a concave body having an upstream side, a downstream side, a leading end and a trailing end. The concave body defines an arcuate crop engagement face facing radially inwardly. A plurality of crop passage openings are defined through the arcuate crop engagement face. A cover is configured to at least partially cover at least some of the crop passage openings. The cover is carried by the concave body and is movable thereon between at least two different positions to adjust a degree of openness of at least some of the crop passage openings.

摘要： A sickle cutting section is provided. The sickle cutting section comprises a plate having a base material of a first hardness. The plate extends forwardly from a mounting portion to a front tip. A serrated cutting edge extends at least partially between the front tip and the mounting portion. A clad material is of a second hardness that is harder than the first hardness and is deposited along the base material at least partially along the serrated cutting edge.

摘要： An agricultural cutting blade has top and bottom surfaces and mounting apertures extending through top and bottom surfaces. A cutting edge support surface (e.g. that may be a flat, pointed or rounded) is formed on the cutting blade body with the cutting edge support extending along a side of the cutting blade body transversely between the top and bottom surfaces. A clad material deposited upon the cutting edge support such as by laser cladding process. The clad material can be built up, that is layered in partial or full overlapping relation to provide at least 2 and often more than 4 layers of clad material at one or more locations. A cutting edge provided by the clad material that may be a ground surface into a laser clad bead.
