Description

Technical Field

[0001] The utility model relates to the technical field of harvesters, in particular to a harvesting platform for a grain combine harvester. Background Art

[0002] The header is one of the main working parts of the combine harvester. Its function is to rely on the cutting system to cut the crops to be harvested, and then the reel wheel will push the crops to the header auger, and the header auger will transport the crops to the intermediate conveying device. The conveying capacity of the auger is related to the auger structure and the gap between it and the bottom plate. Properly increasing the gap between the auger and the bottom plate can improve the conveying capacity of the auger and increase the adaptability of the header to the feed amount. However, when the gap is large and the feed amount is small, the conveying capacity of the auger decreases. However, the existing harvester headers usually do not have the ability to adjust the gap, and the adaptability is poor. In addition, the existing grain dividers on the headers are mostly fixed structures and cannot be adjusted. The grain dividers cannot achieve the best grain separation effect when harvesting different crops at the same time, which affects the performance of combined harvesting. Utility Model Content
