Device with a telescopic or collapsible chute for delivering flowable bulk cargo

Abstract

Apparatus for delivering flowable bulk material such as grain, substantially free of dust into a receptacle, such as a vehicle, wherein the grain is delivered through a filter assembly to a chute which can be elongated and contracted and which has a lower end for connection to the vehicle. The filter assembly is also capable of assuming elongated and contracted states in order to confer a greater free height below the lower end of the chute. The filter assembly is formed with an outside filter housing capable of being elongated and contracted and within the filter housing is a suction chamber downstream of which, one or more filter bags are provided to separate dust from suctioned air. The filter bags can be constructed to prevent radial and longitudinal collapse thereof, as well as to undergo contraction when the chute and filter housing are contracted. An inlet pipe can be provided within the bag to convey the grain to the chute and in the contracted state the chute surrounds the inlet tube.
