#This application claims the benefit of priority from Chinese Patent Application No. 201911146584.2, filed on Nov. 21, 2019. The content of the aforementioned applications, including any intervening amendments thereto, is incorporated herein by reference in its entirety.

#The present invention relates to the technical field of crop harvesting machinery, in particular to an automatic harvesting and collecting device for sisal hemp leaves.

#Sisal hemp leaf fibers are tough, wear-resistant, salt and alkali-resistant, corrosion-resistant. They are widely applied to the transportation, fishery, petroleum, metallurgy and other industries. The sisal hemp leaf is an irreplaceable tropical crop, second only to the natural rubber and palm oil. Sisal hemp fibers play an irreplaceable role in the manufacturing of steel wire rope inner cores for high-grade elevators and stainless-steel polishing cloth, so that the sisal hemp has great market potential. In China, the sisal hemp production areas are mainly concentrated in large-scale farms in Guangdong, Guangxi and Hainan provinces. The sisal hemp planting and leaf production have basically achieved mechanized operations from soil preparation, seedling planting and field management to leaf transportation, fiber scraping, hemp field renovation and other production links. However, no mature model of sisal hemp leaf cutting and harvesting machinery is available in the market at present. The harvesting process accounts for more than half of the labor in the whole production process. In addition, a great number of people are needed in the harvesting process. Therefore, it is necessary to invent the sisal hemp leaf harvesting machinery to solve the problem of cutting and harvesting the sisal hemp leaves.

#The present invention will be further described in detail with reference to the accompany drawings and specific implementation methods.
