The invention discloses a locking device and a dumper provided with the locking device. The locking device comprises an engaging component and a lever component, wherein the engaging component is arranged on a tail door of the dumper, and the lever component is arranged, corresponding to the engaging component in position, on a tail door frame; the engaging component and the lever component can be in two states of locking and releasing after being subjected to relative movement. When the door needs to be locked, extending and extracting the lever component until the lever component is attached to the engaging component, so that the two are in the locking state, and at this moment, the lever component limits the movement of the tail door to avoid that the tail door is opened by mistake; when the door needs to be opened, extending and extracting the lever component until the lever component is misaligned with the engaging component by a certain distance, so that the two are in the releasing state, and at this moment, the lever component does not limit the movement of the door any more, and the tail door can be opened easily. The locking device can be used for effectively engaging and locking through the engaging component and the lever component, the effect is remarkable, the structure is simple, and the manufacturing cost is low.
