1. A vibratory conveyor for bulk material, comprising:
a conveying trough or a conveying tube for accommodating bulk material,
at least one vibration generator functionally connected to the conveying trough or the conveying tube and configured for generating a directed vibratory excitation in order to transport the bulk material in a longitudinal direction through the conveying trough or the conveying tube, wherein the directed vibratory excitation has directional components in the longitudinal direction of the conveying trough or the conveying tube and in vertical direction opposite to a direction of gravity, and
at least one retaining weir arranged in the conveying trough or the conveying tube and configured for decelerating transport movement of the bulk material in the longitudinal direction through the conveying trough or the conveying tube,
wherein the retaining weir has a rear wall pointing in a transport direction of the bulk material and a front wall pointing opposite to the transport direction,
wherein the rear wall of the retaining weir is at least sectionally inclined in an obliquely descending manner from an apex of the retaining weir toward the bottom of the conveying trough or the conveying tube in the longitudinal direction of the conveying trough or the conveying tube, said rear wall having at least one of a plane oblique surface section, a convexly curved surface section, and a concavely curved surface section for contacting the bulk material, and
wherein the length of the front wall measured in the longitudinal direction of the conveying trough or the conveying tube from the runout at bottom side to the apex of the retaining weir is smaller than the length of the rear wall measured in the longitudinal direction of the conveying trough or the conveying tube from the apex of the retaining weir to the runout at bottom side.
