Abstract
A pneumatic material transporter includes a material hopper (2), a screw conveyor (3) to transport the material (supplied from the hopper) from the rear portion to a front portion of the screw conveyor, a pressure chamber portion (5) to receive the materials from the screw conveyor and to press the materials down while adding a limited amount of water, a horizontal mixer (6) adapted to mix the material supplied from the pressure chamber portion with pressurized air, and then push the mixture to a material transporting conduit portion (8) connected to the mixer through a check valve portion, so that the material transporting conduit portion transports the materials to a yard.

An air transporter comprising:
- a material hopper to store material supplied thereto;
- a screw conveyor having a rear portion connected to a lower end opening of said material hopper, said screw conveyor including means for transporting the material (supplied from said hopper) from said rear portion to a front portion of said screw conveyor;
- a pressure chamber portion having an upper opening connected to said front portion of said screw conveyor through a material port, said pressure chamber portion including pressure means to press the material (supplied from said material port) down while adding a limited amount of water;
- a horizontal mixer having a front portion, an intermediate portion connected to a lower opening of said pressure chamber portion and a rear portion connected to a compressed air supply pipe, said horizontal mixer mixing the material (supplied from said pressure chamber portion) with pressurized air (supplied through said compressed air supply pipe) and then pushing the material toward said front portion of said horizontal mixer;
- a material transporting conduit portion connected to said front portion of said horizontal mixer through a check valve portion to transport the material to a yard;
- an openable material gate being provided in said material port;
- and
- sensor means provided in said pressure chamber portion for closing said openable material gate when the material in said pressure chamber portion reaches a predetermined level.
