A shovel is a lever. it has a handle, and one hand sets a fulcrum with the load set opposite the hand that is not the fulcrum. It might be argued that the leading edge of the shovel is a wedge making your shovel a compound machine, but that's cutting things fine.

An airplane is not a simple machine. A lever is a simple machine. A wheel is a simple machine. Any machine that can be described by a mathematical formula is a simple machine.
