According to the working principle of the ship unloader transportation equipment, air type, connecting rod type, buried scraping type, spiral type, corrugated type, chain bucket type, chain bucket type, bucket type, rope bucket type, etc. Introduce several common ship unloaders:
1. Air type ship unloader
Often referred to as a feed absorber, it is mainly used for bulk grain disembarkation operations, and has become the main outboard equipment for modern bulk grain professional terminals abroad. China also has many in Xinsha, Guangzhou. The output of coastal and inland ports such as Shanghai, Tianjin, Zhanjiang and Changsha has reached 4000t/h.
2. Continuous ship unloader
Combined program ship unloader, also known as double-belt ship unloader, was used in Haifa Port in Israel in 1976 and introduced from Dalian Port in 1984. The dual band of the dumper includes a carrier belt and a composite belt. The dual band of the lift section is clamped by compressed air, the material is wrapped in the belt, lifted and transported. The boom conveying section adopts air cushion belt conveyor to work.
When disembarking, first hang the boom, in the material people put down, the two tapes walking at the same time apply pressure evenly on both sides, the material is conveyed to the middle of the tape through the feeding device, and then the material is clamped in the tape for lifting shaft conveying. .
3. Embedded scraper ship unloader
The embedded scraper ship unloader is mainly based on the embedded scraper conveyor, with an output of 300-20000t/h. At the same time, when operating in domestic ports, first put the vertical boom with the feeder into the cabin, and insert the feeder into the material stack. middle. The material flows into the box from the lower end opening of the vertical boom through the feeder, and is pushed by the scraper circulating chain, and the material rises with the rise of the chain.
4. Screw Ship Unloader
The screw type ship unloader is a screw type with a constant output of 500~2000t/h. In many foreign countries, it is mainly used for the loading and unloading of coal mines and fertilizers, and sometimes it is also used for the loading and unloading of grains.
