PNEUMATIC MATERIAL DELIVERY APPARATUS AND METHOD

摘要

Material delivery apparatus mounted on a vehicle (2) for delivering particulate or fine material from an unpressurized container (4) on the vehicle (2) to another location. The apparatus has a vessel (8) having an inlet valve to permit ingress of the particulate material to the vessel (8), an outlet valve to permit egress of the particulate material to the other location, a blower (14) for creating a current of air and a first valve (26) between the blower (14) and a port of the vessel (8). When the blower (14) produces the current of air the apparatus functions in a first mode whereby the particulate material is moved pneumatically from the container (4) to the interior of the vessel (8) and thereafter functions in a second mode whereby the particulate material is moved pneumatically from the interior of the vessel (8) to the other location.
