Cutting device of sugarcane harvester

Abstract

The invention discloses a cutting device of sugarcane harvesters. The cutting device comprises a box body, left and right sawtooth-shaped round cutter discs and left and right transmission shafts, wherein the box body is provided with a transmission mechanism; the transmission mechanism inside the box body drives the left and right sawtooth-shaped round cutter discs to rotate in the opposite directions through the left and right transmission shafts; and the adjacent saw teeth on the sawtooth-shaped round cutter discs are staggered up and down. The adjacent saw teeth on the sawtooth-shaped round cutter discs are staggered up and down; with such structure, persistent and centralized acting force is applied on the sugarcane, so that the sugarcane has a low head damage rate; furthermore adjacent saw teeth are staggered up and down, the cut part of the sugarcane is large in thickness, and the cutter disc are not clamped by the sugarcane, so that the sugarcane is easier to be cut down and the head damage rate of the sugarcane is further reduced; and double cutter discs are adopted for cutting, so that the cutting efficiency is high.

Description

technical field [0001] The invention relates to a sugarcane harvester, in particular to a cutting device for the sugarcane harvester. Background technique [0002] Among the existing sugarcane harvesters, the harvesting is mainly based on the whole rod type. During the walking process of the sugarcane harvester, the rotating shaft on the cutting device is driven by power to make the cutter head on it rotate, thereby cutting off the sugarcane from the root. , and then the sugarcane is sent into the conveying mechanism. The cutting device used to cut off the sugarcane from the root mainly includes a single cutterhead working mode, such as the Chinese utility model patent with the publication number CN2439773Y, the cutting device is installed in the middle of the front lower part of the frame, including a sawtooth circular cutterhead, cutter shaft , belt pulley, the power device on the frame drives the cutter shaft to rotate through the belt pulley, so that the sawtooth circul...

The cutting device used to cut off the sugarcane from the root mainly includes a single cutterhead working mode, such as the Chinese utility model patent with the publication number CN2439773Y, the cutting device is installed in the middle of the front lower part of the frame, including a sawtooth circular cutterhead, cutter shaft , belt pulley, the power device on the frame drives the cutter shaft to rotate through the belt pulley, so that the sawtooth circular cutter head can cut the sugarcane, and the sawtooth circular cutter head can continue to exert force on the sugarcane due to its dense tooth shape, but its The incision on the sugarcane is small, it is easy to clamp the sugarcane on the cutter head, causing the sugarcane to break, affecting the germination and growth of the sugarcane in the second spring, and its working efficiency is low. It is only suitable for small sugarcane harvesters and is not conducive to large-scale sugarcane harvesting. Moreover, the power is transmitted by the pulley, which is easy to cause the belt to loosen, requires shutdown and maintenance, and has a high failure rate

There is also a double-cutter work mode, such as the Chinese utility model patent whose publication number is CN2531619Y. It uses gears to achieve equal linkage speed and opposite direction of rotation. Such a structure has high harvesting efficiency, but there is also a large damage to the sugarcane by the blade. When the sugarcane is not cut by a blade, the cutter head continues to rotate, and the blade is Set at intervals, due to the time difference of sugarcane stress, it is easy to cause a large number of sugarcane heads to break, resulting in a large reduction in the growth and harvest of sugarcane in the second spring, which will affect the growth of sugarcane in the coming year.
