Abstract
A transport assembly for transporting granular material may define at least a first egress for releasing a first portion of a granular material. The device may also include a door assembly slidably coupled with the transport assembly for at least substantially covering the first egress in a first position for retaining granular material and for at least substantially uncovering the first egress in a second position for controllably releasing the first portion of the granular material. The device may also include a linear actuator assembly coupled with the transport assembly and the door assembly for moving the door assembly between the first position and the second position. The device may also include a pump assembly coupled with the linear actuator assembly for actuating the linear actuator assembly to move the door assembly between the first position and the second position.
