Mortar transport apparatus

Abstract

The invention relates to a mortar transport apparatus, consisting essentially of a rotor comprising cylindrical mortar transport chambers, the rotor being arranged between stationary sealing plates and being adapted to be driven by a motor, a feed hopper arranged above the rotor, the feed hopper being adapted to fill the mortar transport chambers via a filling hole provided in the sealing plate situated above the rotor, a blow-off chamber arranged under the lower sealing plate and adapted to have a transport hose connected to it, the blow-off chamber being adapted to be filled via a mortar discharge opening in the lower sealing plate, a duct for supplying air under pressure terminating in a slit-shaped opening in the upper sealing plate above the mortar transport chamber which communicates with the blow-off chamber for driving out the mortar present in the transport chamber, air being supplied to the blow-off chamber at the location opposite the transport hose connection, for pneumatic transport of the mortar through the transport hose. According to the invention the slit-shaped opening (16) is formed by a series of separate spray openings (31) arranged side by side, and arranged for an adjustable water/air mixture to be supplied to them under pressure. The series of spray openings are arranged in a semi-circular pattern (16), the radius of the pattern being about equal to the radius of the transport chamber (10).
