The present invention contemplates an improved material moving apparatus which is particularly useful for blowing insulation material into portions of various structures. The apparatus includes: a hopper, having a chamber; a hopper blade assembly; a blower assembly; and a discharge conduit. The blower assembly includes an air lock positioned about a discharge opening from the hopper, the air lock including a plurality of rotating vanes which divide the air lock into an inlet chamber communicating with the hopper and an outlet chamber through which air is blown. The material is discharged into the hopper chamber, contacted by the hopper blade assembly, and discharged from the hopper chamber into the inlet chamber of the air lock for transfer to the outlet chamber thereof for discharging the material from the material moving apparatus.
