The working process of the central chute is as follows:

1. the chain bucket type continuous ship unloader is used for continuously excavating and lifting materials from a ship cabin, unloading the materials to a horizontal arm support belt type conveying system 005 after multiple transfer, continuously conveying the materials, and transferring the materials through a multi-stage turning-back type central chute 9.

2. The materials thrown out by the horizontal arm support belt conveyor system 005 firstly reach the first buffer table 013, the material flow direction is changed when the first buffer speed is reduced, and the materials reversely fall after the first buffer speed is reduced.

3. The material falling reversely reaches the second buffer table 023, the material flow direction is changed again when the second buffer is slowed down, and the material falls positively after the speed is reduced.

4. The material falling downwards reaches a third buffer table 024, and the material flow direction is changed while the speed is reduced by the third buffer, so that the material falls reversely after the speed is reduced.

5. When the falling material reaches the tail stock guide 003, the falling speed is greatly reduced, and the flowing direction of the material can be controlled by adjusting the angle of the tail stock guide 003, so that the material is centered at the center of the feeding belt conveyor system 006, and the conveyor system is ensured not to deviate.

6. After the operation is finished, all materials on the buffer table can be cleaned completely under the action of the accumulation pushing plate 004, so that the phenomenon of accumulation of materials in the central chute is avoided.

In the embodiment, in the vertical falling conveying process of the material, multi-stage buffering is adopted to form multiple turning-back of the material, so that the falling speed of the material is greatly reduced, the problems of impact, dust emission and the like are fundamentally solved, and the safe, efficient and environment-friendly operation of equipment is ensured.

The central chute provided by the invention has the advantages of simple structure and strong practicability. The first buffer table, the second buffer table and the third buffer table are arranged in the chute, so that the materials are subjected to multistage buffer in the material descending process, and the problems of belt conveyor deviation, carrier roller damage, serious dust emission and the like caused by high-speed impact caused by fall height in the material transfer process of the chain bucket type continuous ship unloader are solved; all materials are conveyed and arranged in the sealing cylinder, the whole process is sealed, no materials are scattered, and the environmental protection performance is improved; the whole device is convenient to assemble and disassemble.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
