摘要： A locking device for a material conveyor. The locking device comprises: a snapping part pivotally connected to a first conveying section (1) or a second conveying section (2) of the material conveyor and capable of pivoting in the pivoting direction of the second conveying section (2), the snapping part being provided with two hooks (8,9); a first post and a second post that are arranged on the second conveying section (2) or the first conveying section (1) not pivotally connected to the snapping part and are used for being matched with the hooks (8,9) in hooking to fix the relative position of the second conveying section (2) and the first conveying section (1) when the second conveying section (2) is in a folded or unfolded state; and a first power mechanism (4) used for driving the snapping part to pivot. The second conveying section can be rapidly and effectively fixed by means of the snapping part and the first power mechanism, so that pin inserting work performed by additional staff near the material conveyor is not needed, and one operator can achieve folding and unfolding of the second conveying section on a driving platform, therefore the folding and unfolding efficiency of the second conveying section is improved and the labor intensity of the operator is relieved.
