Abstract
A material sprayer includes a hopper module and a power module. The power module is mountable and dismountable from the hopper module. The hopper module includes a hopper frame and a hopper supported by the hopper frame. The power module includes a drive and a pump connected to and configured to be powered by the drive. The pump interfaces with the hopper with the power module mounted on the hopper frame such that the pump can draw material from the hopper.
Claims18
A material sprayer comprising:
- a hopper module including:
- a hopper frame;
- a plurality of hopper wheels attached to the hopper frame and configured to support the hopper frame relative to a ground surface;
- and
- a hopper supported by the hopper frame, the hopper including a top opening at a top end of the hopper and through which the hopper is filled with material and the hopper including a hopper outlet at a bottom end of the hopper;
- and
- a power module mountable and dismountable from the hopper frame, the power module including:
- a drive;
- a power module frame;
- a power module wheel attached to the power module frame;
- and
- a pump connected to and configured to be powered by the drive;
- wherein the power module is mountable to the hopper module and dismountable from the hopper module, the power module disposed on the hopper frame when mounted to the hopper module such that the power module rides on and is supported by the hopper frame;
- wherein the pump includes a pump inlet configured to interface with the hopper outlet with the power module mounted on the hopper frame such that the pump can draw material from the hopper.
