A vacuum-based filling device allows a user to transfer quantities of heavy or difficult to manage materials from a dependent position into a delivery system or storage container at a higher elevation or less accessible position. This allows the person filling the delivery system or storage container to remain at a safe and convenient location while operating the vacuum-based filling system. For example, in the case of a feeder for animals, the user is able to fill the storage portion of the feeder from ground level without having to climb a ladder or other unsafe device in order to elevate the feed and place it into the feeder. The vacuum-based filling device uses a motor to create a vacuum within the storage container via a hose connected between the vacuum motor and storage container. Another hose is coupled between the storage container and a container holding the feed. The vacuum created within the storage container draws the feed from its container into the storage container. |
