Abstract (en)
[origin: EP0456911A1] The invention relates to a mixer-transport apparatus for floor mortar and the like, comprising a mixing tank having a filling hole that can be sealed and a transport hose connected to the mixing tank for the pneumatic transport of an earth-humid sand-cement mixture to a site where it is used. According to the invention a remote-controlled shut-off valve (23) is arranged for pivotal movement about a vertical shaft (20) is arranged at the filling hole (18) of the mixing tank (5). The vertical valve shaft (20) can be moved vertically over an adjustable distance (X) between a pivoting position, in which the valve (23) is just clear of an O-ring (17) mounted in an annular groove (16) provided in the bottom surface of a ring (14) surrounding the filling hole (18), and a sealing position, in which the valve (23), owing to the pressure in the mixing tank (5), is pressed into sealing engagement with the O-ring (17). <IMAGE>
