<p>A bulk container comprises a box body with an open top, a top plate arranged at the open position of the box body and provided with a top hole and a top cover capable of covering the top hole, a connection rod, two guide rails and at least a pair of roller wheels. The two guide rails are arranged in parallel and respectively located on two opposite sides of the top hole. The connection rod is vertically arranged between the two guide rails and connected with the top cover in rotating mode. Two roller wheels in the pair of roller wheels are respectively connected with two ends of the connection rod. The central axes of the roller wheels are parallel and not overlapped with that of the connection rod, and the two roller wheels can be respectively embedded in the two guide rails movably along the guide rails. The top cover of the bulk container rotates eccentrically, is lifted automatically and is opened in sliding mode. The top cover occupies a small height space when being opened, so that the container reduces labor intensity in operation and is safe and reliable. Further, a rubber strip at the bottom of the top cover is in the loosing state when the top cover slides, abrasion of the rubber strip is avoided, and box maintaining cost is reduced. A limit mechanism can be further arranged to prevent the top cover from sliding to the top hole when the top cover is opened.</p> |
