Open-close type chain cutter sisal hemp harvesting device

Abstract

The invention relates to an open-close type chain cutter sisal hemp harvesting device. The open-close type chain cutter sisal hemp harvesting device comprises an open-close type chain cutter cutterhead mechanism for clamping and cutting sisal hemp, a circumference feeding mechanism for driving the open-close type chain cutter cutterhead mechanism to rotate around a circle center on a horizontal plane, a circle center feeding mechanism for driving the open-close type chain cutter cutterhead mechanism to leave far away and approach to the circle center on the horizontal plane, and a Z-direction feeding mechanism for driving the open-close type chain cutter cutterhead mechanism to vertically move. The open-close type chain cutter cutterhead mechanism comprises an open-close cutterhead mechanism and a chain cutter mechanism; the open-close cutterhead mechanism comprises a fourth motor, a worm and gear mechanism and two circular arc-shaped cutterheads; the chain cutter mechanism comprises a fifth motor, a chain, a driving chain wheel, a driven chain wheel, a tensioning wheel, a tensioning mechanism, a crescent cutter blade and a cover plate; and the crescent blade is arranged at the outer side of the chain and forms a chain cutter structure with the chain. The open-close type chain cutter sisal hemp harvesting device provided by the invention solves the mechanical harvesting problem of sisal hemp leaves, ensures the harvesting efficiency and the harvesting quality, and belongs to the field of sisal hemp harvesting equipment.

Description

technical field [0001] The invention relates to the field of sisal harvesting equipment, in particular to an opening and closing chain knife sisal harvesting device. Background technique [0002] At present, the mechanized harvesting level of sisal in my country is very low, there is no mature sisal harvester on the market, and the picking of sisal leaves is all done by manual cutting. From the point of view of the entire production process of sisal, soil preparation machines, field management machines, leaf cutters, and processing machinery are generally required. From the perspective of the mechanization level of each link, the mechanization level of only the leaf cutting link is almost zero, and still requires A lot of manual work, the tools that can be used in actual work are just some simple auxiliary tools, such as sickles, electric leaf cutting hand saws, etc. Therefore, realizing mechanized harvesting of sisal leaves is a technical problem that needs to be solved urg...

AI Technical Summary

Problems solved by technology

At present, collecting and transporting sisal in the field is no different from other crops that have been mechanized. Cutting leaves has never been fully mechanized at home and abroad because of its complexity and difficulty.
