Description

Technical Field

[0001] The utility model relates to the field of lifting bases, in particular to an omnidirectional leveling liftable chassis device for a combine harvester. Background Art

[0002] At present, the combine harvesters on the market are mainly divided into two types: semi-feed and full-feed. Both full-feed and semi-feed have their own advantages. Semi-feed combine harvesters use a vertical cutting table, and full-feed combine harvesters use a reel plus cutter mode to achieve the cutting of stalks and stems. Due to their different structures, they are directly related to the operation effect ratio.

[0003] A typical example of a double-cutting vertical header for combine harvesters currently on the market is the one disclosed in an invention patent application filed on October 31, 1996. While this double-cutting header ensures that only the ears enter the threshing drum, it is a horizontal header with a large longitudinal dimension. The long distance over which the ears are transported increases the loss rate during transport and reduces harvesting efficiency for severely lodged crops. It is only suitable for use with traditional full-feed combine harvesters. Its large size and weight make it difficult to transport, hindering the harvester's cross-regional operations.
