Abstract
A material spreader includes a hopper that defines a hopper interior, a hopper exterior, and an opening that extends from the hopper exterior to the hopper interior. The material spreader also includes a shaft that extends through the opening, and a fastener that interfaces the hopper and the shaft at the opening, where the fastener supports and aligns the shaft on the hopper. The material spreader also includes a seal connected with the shaft and the fastener in the hopper interior, where the seal extends over the fastener, outward from the shaft toward an outer perimeter of the fastener.
Claims40
A material spreader comprising:
- a hopper that defines a hopper interior, a hopper exterior, and an opening that extends from the hopper exterior to the hopper interior;
- a shaft that extends through the opening;
- a fastener that interfaces the hopper and the shaft at the opening, wherein the fastener supports and aligns the shaft on the hopper;
- and
- a seal connected with the shaft and the fastener in the hopper interior, wherein the seal extends over the fastener, outward from the shaft toward an outer perimeter of the fastener.
A material spreader comprising:
- a hopper that defines a hopper interior, a hopper exterior, and an opening that extends from the hopper exterior to the hopper interior;
- a shaft that extends through the opening in a longitudinal direction;
- a fastener that interfaces the hopper and the shaft at the opening, wherein the fastener supports and aligns the shaft on the hopper;
- and
- a seal that extends over the fastener, outward from the shaft in a radial direction perpendicular to the longitudinal direction, toward an outer perimeter of the fastener.
A material spreader comprising:
- a hopper;
- a shaft pivotally fixed with the hopper;
- a cam fixed with the shaft;
- and
- an agitator disposed in the hopper, wherein the shaft is operably connected to the agitator through the cam in the hopper interior such that rotating the shaft causes reciprocating motion in the agitator.
