Movable type chain bucket ship unloader

Abstract

The invention provides a mobile chain bucket ship unloader, which includes a retrieving mechanism, a conveying mechanism and a control mechanism. It is a chain-bucket reclaiming and lifting mechanism, and the conveying mechanism is a cantilever conveying mechanism. The chain-bucket reclaiming and elevating mechanism is connected with the cantilever conveying mechanism. A positioning mechanism is provided on the mechanism, and the positioning mechanism is controlled by a control mechanism. The positioning mechanism includes: a cantilever pitching mechanism and a cantilever turning mechanism. The invention provides a mobile chain-bucket ship unloader, which is a continuous type of retrieving and conveying, with fast unloading speed and wide application range; The unique swing mechanism can also take out the materials under the deck; the reclaiming section of the reclaiming system is equipped with a hydraulic tensioning device, which can reclaim the materials smoothly and completely remove the residual materials.

Description

technical field [0001] The invention relates to the technical field of ship unloaders, in particular to a mobile chain-bucket ship unloader with high material retrieving efficiency, low loss, strong adaptability and stable material retrieving. Background technique [0002] At present, there are several processes for bulk unloading: [0003] 1. Bridge type grab ship unloader, which takes materials through grab buckets. For example, CN103287984A discloses bridge type grab ship unloader, including steel structure system, operation system and unloading system. The unloading system includes a receiving plate system , a funnel and a feeding belt conveyor, the feed board system includes a sea side feed board, an intermediate feed board and a land side feed board, and the sea side feed board, the middle feed board and the land side feed board They are respectively installed on the sea-side column, funnel and land-side column. The feeding belt conveyor is a rotary belt conveyor. A ...

AI Technical Summary

Problems solved by technology

The bridge type grab ship unloader with this structure is generally suitable for granular materials, the maximum output is only 1000 tons / hour, and the efficiency is poor;

[0004] 2. Through the form of transportation, the energy consumption is high; it is not suitable for powder materials;

The screw ship unloader with this structure has a large investment, and during the process of material retrieving and conveying, the reclaiming head and the screw blades are greatly worn, and the maintenance cost is high;

[0006] 4. Pneumatic ship unloader, such as CN205061019U discloses a high-throughput high-negative pressure pneumatic ship unloader, including suction nozzle, material delivery pipeline, intermediate storage silo, separator and its purging system, unloading lock air device and its intelligent control system, and Roots vacuum pump; it is characterized in that the suction nozzle is connected to the middle storage bin through the feeding pipeline, and the bottom of the middle storage bin is a hopper, which is connected to the unloading air locker, The separator is located in the upper part of the intermediate storage bin, and the upper part of the separator is a clean air chamber. The separated gas from the material-gas mixture is discharged from the outlet of the Roots vacuum pump, and the material is discharged from the outlet of the unloading air lock. The pneumatic unloading of this structure Marine machinery, suitable for powder materials, has a narrow application range, and cannot be used for corrosive, viscous, etc.
