Abstract
A mobile vehicular mounted pneumatic conveying apparatus is disclosed which comprises a self-propelled vehicle having an elongated boom capable of being elevated and rotated relative to the vehicle, with the boom having a nozzle structure mounted on the other end thereof for engaging dry particulate material to be conveyed. The apparatus also has a material transfer assembly which includes at least one closed vessel for receiving material from said nozzle under vacuum pressure and for subsequently expelling material into a conveying line under positive pressure. The transfer assembly can be easily removed from the vehicle and a rearward carriage that is attached to the transfer assembly can similarly be removed. The apparatus is particularly adapted for conveying large quantities of dry, particulate material such as Portland cement from a large horizontal storage building as opposed to a vertical silo or the like. Support equipment is preferably located externally of the building and a unique distribution system for supplying positive and vacuum pressure to various distribution ports enables a very large surface area to be covered by selectively connecting the apparatus to one of t…
