Abstract

A discharge device includes a plurality of material conveying components, an adjustable shear ledge, and an adjustable shroud to convey materials from a container of a material spreader out onto an open area. The adjustable shear ledge includes at least one longitudinal mounting member such that the adjustable shear ledge may be translated towards or away from the plurality of material conveying components to maintain a predetermined gap distance. The adjustable shroud may also be pivotably connected to the adjustable shear ledge such that the adjustable shroud can be pivoted towards or away from the plurality of material conveying components. The adjustable shear ledge and the adjustable shroud may be moved accordingly to maintain a preferred gap distance and to maintain concentricity with a swing of the material conveying components in order to reduce wear on components and promote spread performance of the material spreader.

Dependent claims

A material spreader for spreading materials from a container onto an open area including a discharge device disposed on a first side of the container, the discharge device comprising:

a housing including a plurality of material conveying components, the housing being attached to a sidewall of the container;
an adjustable shear ledge having an arcuate shear top surface, the adjustable shear ledge being mounted to the container adjacent to the plurality of material conveying components;
and
an adjustable shroud having an arcuate shroud top surface, the adjustable shroud being mounted to the container adjacent to the plurality of material conveying components,
wherein the adjustable shear ledge includes at least one longitudinal mounting member, the at least one longitudinal mounting member allowing the adjustable shear ledge to translate along a first axis to bring the shear top surface towards or away from the plurality of material conveying components, and
wherein the arcuate shear top surface of the adjustable shear ledge and the arcuate shroud top surface of the adjustable shroud are substantially concentric with a swing path of the plurality of material conveying components, and are substantially continuous with each other along the swing path of the plurality of material conveying components.
