[0002] The bucket elevator is a conveying equipment commonly used in port wharf, grain processing and mineral exploitation industry, and is used for conveying powdery, granular and small block materials vertically or obliquely. Due to the structural relationship, the hoist base, especially the internal residual material of large hoist base, is more, and if not cleaned for a long time, the material can be mildewed, germinated and hardened, which not only affects the use of equipment but also causes environmental pollution. The residual material of conventional large hoist base is cleaned manually, which not only wastes labor but also has a poor working environment, and the cleaning is not clean. The ordinary self-cleaning base realizes self-cleaning through the discharge adjusting base, but the adjusting device is easy to be dusty and hardened after long-term use, and then cannot be cleaned, which causes the self-cleaning mechanism to fail and the hoist itself cannot be used.

[0003] Therefore, it is necessary to design a tail self-cleaning system of bucket elevator to solve the above problems. CONTENT OF THE UTILITY MODEL

The four reversing gears are driven by a chain, and the chain passes through the material receiving seat. The chain is evenly provided with a plurality of flexible scrapers along the running direction. One of the reversing gears is provided with a power mechanism for driving the reversing gear to rotate.

[0007] The material receiving seat comprises a material receiving pipe; two ends of the material receiving pipe are connected with end portions of the feeding pipe and the discharging pipe respectively; a top portion of the material receiving pipe is provided with a material receiving hopper; inner walls around the material receiving hopper are all arranged to be inclined towards the middle portion.
