A kind of ramie fiber harvesting method

Abstract

The invention provides a method for harvesting ramie. The method includes the steps of A, material feeding and first-time ramie separation through a ramie stalk clamping main machine and B, second-time ramie separation through a fiber clamping auxiliary machine and fiber output; a ramie cutting step is further performed between the step A and the step B, and in the ramie cutting step, a sliding-cutting mechanism is arranged between the output end of a ramie stalk clamping and conveying device and the front section of a fiber clamping and conveying device, and composed of a blade and a blade clamp, is triangular, and is fixed on the left side of an installing plate of a second shaftless belt wheel and a third shaftless belt wheel. With the sliding-cutting mechanism, first-time main machineramie separation and second-time auxiliary machine ramie separation are stably engaged with fiber outputting.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a method for primary processing of hemp fibers, in particular to a method for harvesting ramie fibers. Background technique [0002] Ramie is a traditional characteristic economic crop in my country. Ramie fiber is known as the king of natural fibers, and ramie leaves are rich and comprehensive in nutrition. Ramie needs to be harvested in good time, the fibers are not fully developed when harvested too early, the ramie skin is thin and the output is low, and the physical and mechanical properties of the fibers are poor, resulting in a low yield of ramie and poor fiber quality; It is not easy to separate on the surface, resulting in a decrease in fiber strength and a decrease in the yield of hemp, which affects the output and economic income of ramie. [0003] Ramie is generally harvested three times a year. In the traditional manual harvesting method, harvesting ram...

Problems solved by technology

The third is that the machine completes the cutting and collecting operations by the cutting device and the finished product integration box. The unprocessed hemp stalk at the rear base held by the clamping device is cut by the cutting device, and the loss is too great to lose, and it is not easy to reprocess and utilize.

[0008] The machine has both mechanical transmission and airflow transmission, and the structure is relatively complex. The fiber is blown into the clamping mechanism by airflow, and the reliability is poor. The hemp feeding needs to be manually placed into the inner side of the hemp stalk clamping conveyor belt, and the degree of automation is low. It is not high enough to be directly matched with vertical headers to achieve combined harvesting of ramie fibers, let alone be matched with vertical headers of horizontal double headers ramie fiber feeding double harvesting combine harvester to realize combined harvesting of ramie fibers
