Description
Technical Field
[0001] The utility model relates to the technical field of sand dredging ship gear boxes, in particular to a high-strength middle box structure of a sand dredging ship gear box. Background Art
[0002] A sand dredger is a floating mining and selection combined device for mining underwater sand deposits or loose materials. The ore sand is mined by the excavation mechanism installed on the flat-bottomed bow and lifted to the ship's silo. After being crushed, washed and graded by the circular screen, the fine-grained materials containing ore flow by gravity into the roughing chute or jig for roughing. The tailings are discharged into the goaf behind the stern through the tailings chute or sand pump, and the waste rock on the circular screen is discharged into the tailings pile behind the stern through the belt conveyor or gravel chute. Since this type of floating device was originally used to mine gold in New Zealand, it was named a gold dredger. Later, it was also used to mine platinum, cassiterite, diamond, rutile, monazite, zircon, sulfur, phosphate, coal, silver, ilmenite, silver-containing lead-zinc ore, iron sand, niobium, tantalum, thorium and other minerals and sand and pebbles for construction. All methods of using sand dredging ships to mine useful minerals are collectively referred to as sand dredging ship mining, or ship mining for short. With the development of society, when the gearbox of the sand dredging ship needs to be protected, the middle box structure is used.
[0003] When workers need to protect the internal parts of the gearbox, they install the middle box structure in the middle of the gearbox so that the middle box structure can protect the internal parts of the gearbox. However, the existing middle box structure will be in contact with water stains for a long time during use, causing serious rust on the surface of the middle box structure, which in turn leads to a reduction in the strength of the middle box structure.
