A device for collecting and discharging solid refuse matter, flowing in sewers includes a grid (15) comprising stationary and displaceable bars (17, 18). The edges of the bars turned towards the flow of water are stepped and the terraces (19) of the steps form the lifting part of a conveyor. The pattern of movement at the displaceable bars is such that a vertical net component of movement is obtained at the lifting parts.
