Vehicle for bulk transport of powder-form, granular or pellet-like material

A vehicle for transport of bulk material of powder, granular or pellet-like material comprising a plurality of reservoirs, means for filling each of said reservoirs with bulk material, said reservoirs having upper portions thereof interconnected with one another, a source of compressed air connected with said interconnected portions for discharging bulk material from said reservoirs, a discharge pipe including an outlet for discharging bulk material from the vehicle, discharge means at the lower portions of said reservoirs, each of said discharge means defining a discharge opening in communication with said pipe, said discharge means having a substantially cylindrical sealing surface and defining a first circular edge, closing means mounted for axial movement relative to said discharge means in a first direction to open the discharge means and in a second direction to close the discharge means, said closing means carrying an annular resilient sealing ring which engages said sealing surface in the closed position, said closing means having on the lower part thereof a circular cutting edge engageable with said first edge prior to engagement of said sealing surface and sealing ring when said closing means moves in said second direction to close the discharge means to thereby break up any pellet-like or granular bulk material which might otherwise lodge between the sealing ring and the sealing surface and prevent an effective airtight seal.
