Description
Technical Field
The invention relates to the field of agricultural machinery, in particular to a hemp harvester.
Background
Hemp is a plant of Moraceae and Cannabis, and has long and tough stem bark fiber, and is used for weaving hemp cloth or spinning thread, making rope, etc., and seed oil has oil content of 30%. The fruit is called fructus cannabis in traditional Chinese medicine and has medical effect. Hemp also has the effect of continuously reducing petroleum hydrocarbon pollutants in the polluted soil until the content of the pollutants reaches the national environmental standard. China hemp is an annual upright herbaceous plant, is mature in the current cultivation technology, and has a set of systematic sowing and fertilizing measures and a scientific field management system. However, the maturation periods of the female and male China hemp plants are not consistent. The male plant is mature in the late flowering stage, and the female plant reaches seed maturation only when the seeds in the middle of the inflorescence of the main stem are mature. The mature periods of the female and male plants are different by 30-40 days. Thus, hemp is generally harvested in stages. The male plant is harvested at the end of the flowering period of the male plant for the first time, and the female plant is harvested at the middle part of the inflorescence of the main stem of the female plant when the seeds are mature for the second time. Harvesting in the morning and evening has a great relationship to hemp fiber yield and quality. Tests show that the fiber is harvested in the flowering period of a male plant, and the fiber yield is high and the quality is good; the later the harvest, the higher the yield, but the coarse and hard fibers, the poor quality; early harvest resulted in immature fibers, white and soft fibers, but reduced strength. According to investigation, reaping and cutting by using a sickle to be flat and flat, then beating hemp leaves completely, cutting off tips, and bundling according to the height, the thickness and the maturity of hemp stems in a grading way to prepare retting hemp. And harvesting the ramie in the same day, and loading raft and retting the ramie in the same day. It can be seen. China has low mechanization level of China hemp harvesting production, China's hemp harvesting work is basically finished manually, the labor intensity is high, the efficiency is low, the waste rate is high, the working environment is poor, the shortage of labor force and the rising price increasingly limit the market prospect of expanding the China's hemp production scale.
