A conveyance apparatus (1) according to an embodiment includes: a trough (11) that receives an article from an outside and conveys the article in a conveyance direction from upstream to downstream; and a drive unit (20) that drives the trough. The trough includes a plurality of protrusions (92) on a front surface (91) on which the article is conveyed, and an opening (91A) passing from the front surface to a back surface (93) is formed at an end (92E) on a downstream side of the plurality of protrusions.

A vibratory conveying apparatus (10) comprises a trough (20) for conveying articles from an upstream side to a downstream side, a vibrator (30) for vibrating the trough (20), and an attachment/detachment mechanism (40) for attaching and detaching the trough (20) and the vibrator (30). The attachment/detachment mechanism (40) has a trough-side attachment/detachment member (50), a vibrator-side attachment/detachment member (70), and a lever (65). The trough-side attachment/detachment member (50), which is secured to a trough bottom plate (21), has a protruding part (55) disposed on the upstream side and an eccentric cam (66) disposed on the downstream side. The vibrator-side attachment/detachment member (70), which is secured to the vibrator (30), has a protruding part (72) disposed on the upstream side and a bent part (73) disposed on the downstream side. The lever (65) is configured to be moved up and down to switch between a fixed state in which the trough-side attachment/detachment member (50) and the vibrator-side attachment/detachment member (70) are fixed to each other, and a separated state in which the two members are separated from each other.
