Background
Flax is the earliest natural plant fiber used by human beings, originates from coasts of the east and the Mediterranean, and has the characteristics of strong tension, softness, good fineness, weak electric conduction, quick water absorption and dispersion, large expansion rate and the like, and can spin high count yarns and high-grade clothing. Development of agricultural mechanization is an urgent need for construction of modern agriculture. Agricultural mechanization is the development direction of modern agriculture, and flax working machines mainly comprise seed cleaning machines, seeding machines, flax pulling machines, threshing machines, turnover threshing machines, flax turning machines, bundling machines, decorticators and the like.
Timely harvesting of flax is a key to ensuring high yield and harvest of flax and improving fiber quality. The harvesting is too early, the fiber is too mature, the hemp stems are easy to fall green and stand, the quality of hemp is reduced, and currently, a self-propelled hemp pulling machine and a Russian combined hemp pulling machine are mostly adopted in China. With the development of the whole-process mechanized production technology of flax, the whole-process mechanized production of flax is a precondition and foundation of high quality and high yield of flax during mechanized harvesting of flax, and the traction flax harvester has the defects of superposition of harvested flax layers, large inclination angle of the flax layers, poor uniformity of roots and the like due to the limitations of the structure and the principle of the flax harvester, so that great inconvenience is brought to subsequent mechanized operation, and even mechanical flax turning, threshing and bundling operation cannot be performed subsequently. The self-propelled flax harvester plays an important role in the whole-process mechanical operation of flax.
However, the self-propelled flax harvester in the prior art is mechanically driven, and the transmission gearbox in the self-propelled flax harvester is required to complete the walking function, the flax pulling function of front power output and the flax conveying and spreading function of side power output. Therefore, the transmission gearbox has the advantages of complex structure, extremely high failure rate, long maintenance period and low productivity. In addition, the self-propelled flax harvester in the prior art is a single-line operation harvester, namely, two front clamping conveying channels are arranged behind two adjacent flax pulling operation areas on the left side and the right side of the flax pulling table, and two steering wheels are arranged at the rear end in parallel up and down. Therefore, the production efficiency is low, the large-area flax planting cannot be met, the relative cost is high, the wheel track is narrow, the flax is easy to press, the flax is damaged and lost, and the harvesting requirement condition is high.
