ABSTRACT:
Apparatus for handling particulate material, such as wood chips or the like in which a pneumatic conveying tube is manipulated to discharge a stream of wood chips or other particulate material toward a specific location as in the bulk loading of trucks or railway cars. An elongate rigid material conveying tube is coupled at one end to a receiving unit which includes a material receiving hopper and a penumatic blower for propelling material from the hopper into and through the tube. The opposite end of the tube is suspended from a mast assembly mounted upon a power-driven carriage which moves independently of the material receiving unit to position the discharge end of the tube at the desired location. A curved discharge section at the end of the tube may be rotated relative to the tube to direct the stream of discharged material to one side or the other of the tube. A normally closed cover plate on the curved discharge section may be opened and the normal discharge opening simultaneously closed to enable the material to be discharged in a stream directed substantially coaxially of the elongate tube.
