In a preferred embodiment, there is a longitudinal flow through the horizontal crossbars consisting of a U-shaped curved cavity of the crossbar below the sheet metal, the open side of which results in the bottom of the conveyor trough. The longitudinal flow through which is facing and on both sides between the side cavities can be reinforced in an advantageous manner thereby tenwände of the conveyor trough 1 and the end plates 6 that additionally has the cross-section of the lateral extensions. The open side of the profile 20 has air inlet openings 12 (underneath the large one is tightly welded by a sheet metal 7. The two mouth openings 10) are made smaller than the sides between the side cheeks 3 and 4 and than the cross section of the lateral air inlet openings Conveyor trough 1 arising gene 13 (below the smaller mouth opening drainage channels 8 and 9 point approximately at the level of the trough 11). .

On the top, the space between the side walls of the frame and the vibrating machine is covered over its entire length with a dust extractor hood 14 that is sufficiently fixed to the side winds of the conveyor organ, which is able to effect the dimensions.

This simple measure will A negative pressure via the conveyor trough, so that from the outside pressure generated in an advantageous manner The flow of air into this space differs from a longitudinal flow through the hollow indulgence. A part of the air volume drawn in occurs through traverses.
