Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a wheeled self-propelled full-feed rapeseed combine harvester aimed at the rapeseed planting mode in Northwest China. Background technique [0002] In the current era of rapid development of China's manufacturing industry, rapeseed is the main oil crop in Northwest China. The harvesting method of rapeseed is still mainly manual harvesting, supplemented by segmented mechanical harvesting, and a small amount of combine harvesters. The machine-harvesting level is far lower than that of southern rapeseed, and its mechanization rate is significantly different from other crops in the region. The reasons for this phenomenon are, firstly, the biological characteristics of the rapeseed plant itself, which brings difficulties to mechanical harvesting; [0003] (1) Compared with wheat, rice, highland barley and other crops, the northern rapeseed plant is taller, and its height is betw...

Problems solved by technology

[0003] (1) Compared with wheat, rice, highland barley and other crops, the northern rapeseed plant is taller, and its height is between 1.5-2m or even more than 2m, which brings difficulties in dividing and repelling; and the thick and high sugar content of the stalks increases cutting Difficulty; more branches, longer pod section, in order to avoid losses, the full feeding method is adopted to harvest, resulting in a high proportion of grass seeds, and a large load of threshing and separation; pod-shaped siliques, which are easy to burst when mature and collide, which brings inconvenience to mechanical harvesting ; The moisture content of the stalk is high, which is not conducive to cleaning and separation; the cut stalk is long and has too many branches, which is prone to blockage

[0004] (2) Rapeseed planting in Northwest China is mainly based on dense planting modes such as drill sowing and broadcasting. The mature rapeseed branches are entangled with each other, making it impossible to divide the crops, while Hunan, Hubei, Sichuan and other southern regions use crop cultivation Mode-based, the mature rapeseed branches are less entangled; the rainfall, temperature difference, and sunshine in the southern region are relatively stable, and they are committed to rapeseed breeding. The cultivation height is consistent and the maturity period is consistent for machine-harvested varieties. Therefore, the combined harvester Most of the cutting platforms are rigid and non-adjustable structures, while the same species in the mountains and basins in the northwest region form local microclimates on the mountains, under the mountains, in front of the mountains, and behind the mountains, which further amplifies the biological characteristics of the plants, and the height of the crops is uneven. The height of the platform and the height of the eccentric reel shaft can be adjusted in a larger range; also due to the continuous and uneven mountains, rapeseed is planted on slopes with different slopes. Compared with the large-scale planting mode in the south, rapeseed in the Northwest is planted in blocks and in small areas under the limitation of geographical factors, making the crawler-type combined harvesting machinery suitable for field operations in the south, Operating efficiency in the north is significantly reduced

[0005] Compared with the rapeseed planting mode in the south, the biological characteristics of rapeseed in Northwest China are further amplified due to reasons such as the ground environment, climatic conditions, and breeding techniques, making rice and wheat combine harvesters and rapeseed harvesting machines in the south unsuitable for the unique Northwest region.
