Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural machinery technical field, concretely relates to a self -propelled flax puller header. BACKGROUND

[0002] Flax fiber has high strength, moisture absorption, air permeability, heat conduction, anti-static, anti-ultraviolet and other properties, and can be spun into high-grade clothing, and its textiles have unique advantages and occupy a large market. Flax can be planted in a wide area in China, and the area is large. Under the premise of ensuring food production, only Heilongjiang province has 4666.67 mu of land suitable for flax planting, so flax planting has a good prospect. Timely harvesting is the key to ensuring the yield and quality of flax fiber. If harvesting is too late, it is easy to cause fiber yield and quality to decrease. At present, most of the flax harvesting in China adopts self-propelled flax puller and traction type flax puller. The traction type flax puller has the disadvantages of overlapping, large inclination angle and large root difference during operation, which seriously affects the subsequent mechanized production. The self-propelled flax puller plays an important role in the whole process of flax mechanized production, but the existing self-propelled flax puller header uses rubber belts and hanging rubber wheels to form an arc-shaped clamping surface to clamp the stems for operation. The single rubber belt and hanging rubber wheel clamping has large and uncontrollable pressure between the rubber belt and the hanging rubber wheel, which causes large damage to the stems, causes the damaged parts of the stems to be easily over-rotted, reduces the fiber strength, and seriously affects the long flax rate. The stems are rigidly tensioned during the conveying process, which further increases the damage rate of the stems during conveying, and the root difference is low in uniformity. Therefore, it is necessary to optimize the design of the self-propelled flax puller header. The design adopts two same-specification hanging rubber wheels to clamp the stems for operation by sleeving rubber belts to form a straight slightly inclined clamping surface. The double rubber belts and the double hanging rubber wheels are adjusted at the same time, the conveying belt is self-excited tensioned, the stems are less damaged, the root difference is high in uniformity, the structure is simple, and the adjustment is easy.
