Description

Closed cab suitable for large-tonnage underground scraper Technical Field The utility model relates to the technical field of earthmoving machinery, in particular to a closed cab suitable for a large-tonnage underground scraper. Background The scraper is a soil-shoveling and transporting machine which can shoveling soil by utilizing a bucket and loading crushed soil into the bucket for transporting, can finish comprehensive operations of shoveling soil, loading soil, transporting soil, unloading soil, filling soil in layers and locally compaction by rolling, is suitable for working on flat sites of projects such as railways, roads, water conservancy, electric power and the like, and has the advantages of simple operation, no limit by topography, independent working, high running speed, high production efficiency and the like. In a downhole mining operation scenario, a closed cab for a downhole scraper is typically provided with a door that facilitates access by the driver.
