Harvester for leaves of agave sisalana

Abstract

The invention discloses a harvester for leaves of agave sisalana. A lifting frame is movably connected up and down with the front end of a vehicle body, a piston is transversely fixed at the front endof the lifting frame, a piston rod of the piston extends towards one side of the vehicle body, and a harvesting device is fixed at the end part of the piston rod; and the harvesting device comprisesa ring sleeve, a hollow cavity is arranged in the ring sleeve, a groove opening is arranged in the middle of the top surface of the ring sleeve, an annular rod which is in slide connection along the ring sleeve is arranged in the ring sleeve, one side, far away from the piston, of the ring sleeve is provided with a gap A, the annular rod is provided with a gap B, the straight line distance of a gap with a smaller radian in the gap A and the gap B is greater than or equal to the diameter of the stem of the agave sisalana, the top, located at in the range of the groove opening, of the annular rod is inwards provided with cutting knives, and the distance between each cutting knife and the circle center of the annular rod is greater than the radius of the stem of the agave sisalana. Accordingto the above structure, the harvester for the leaves of the agave sisalana provided by the invention realizes mechanized harvesting of the leaves of the agave sisalana, thereby changing the industry rule that the agave sisalana can only be manually harvested, greatly reducing the labor intensity of harvesting of the leaves of the agave sisalana, and improving the harvesting efficiency of the leaves of the agave sisalana.

Description

technical field [0001] The invention relates to the technical field of harvesting sisal leaves, in particular to a harvester for sisal leaves. Background technique [0002] Hemp fiber refers to fibers obtained from various hemp plants, including bast fibers from the cortex of annual or perennial herbaceous dicotyledonous plants and leaf fibers from monocotyledonous plants. Bast fiber crops mainly include ramie, jute, green hemp, hemp, flax, apocynum and kenaf. Generally speaking, hemp fiber is a high-strength and low-elongation fiber, and its breaking strength is 5.0~7.0cN / dtex (2.6~4.5 for cotton fiber and 3.0~3.5 for silk). This is mainly because hemp fibers are mainly bast fibers, and bast fibers are the basic skeleton of plants, with high crystallinity and orientation, and the fibrils are distributed in a layered structure along the fiber radial direction. For example, flax has 90% crystallinity and nearly 80% orientation. Because of its high crystallinity and orienta...

AI Technical Summary

Problems solved by technology

However, because the fiber yield of sisal leaves is very low, generally less than 4%, the harvest of sisal leaves is extremely large

Due to the huge amount of harvesting, a lot of manual work is required, resulting in huge labor costs
