LARGE-TONNAGE NARROW AND LONG EXTERNAL FORCE TYPE BEND UNLOADING SKIP BUCKET

摘要

A large-tonnage narrow and long external force type rail unloading skip bucket comprises an upper box body (1), a lower box body (2), a self-locking gate (6), and a gate opening apparatus. The upper box body (1) and the lower box body (2) are separately formed by fixedly connecting inner layer liner plates (10-1) and outer layer liner plates (10-2) into a whole by means of a plurality of pins (11). The upper portion of the upper box body (1) is provided with a loading port and a spillplate (4) for blocking coal in a process of coal loading. The lower box body (2) is provided with the self-locking gate (6) consisting of sector gate plates (6-1) and unloading idler wheels (6-2). The lower portion of the self-locking gate (6) is provided with a coal sliding apparatus (7). The upper box body (1) and the lower box body (2) are connected by means of a flange (5), and a steel channel (9) is welded to each of the outer wall of the upper box body (1) and the outer wall of the lower box body (2) in a surrounding manner. When the skip bucket is located at an unloading position, an external force telescopic push rod (13) pushes the unloading idler wheels (6-2) to move inside an unloading rail (12-1) of a sliding block (12) to open the self-locking gate (6), and the coal is unloaded along the coal sliding apparatus (7). Because the upper box body (1) and the lower box body (2) are reliably connected, the inner layer liner plates (10-1) are effectively and conveniently fixed and the self-locking gate (6) is reliably opened, the skip bucket can meet requirements of a large mine with a ten-million-ton scale.
