Description

Sugarcane Harvesting Mechanical Cutting Conveyor System with High Feeding Capacity

(1) Technical field:

The utility model relates to a sugarcane harvester, in particular to a cutting and conveying system for sugarcane harvesting machinery with strong feeding capacity, which can be used on the whole pole type sugarcane harvester, and can also be used on the cutting type sugarcane harvester.

(2) Background technology:

The sugarcane harvesting mechanical cutting and conveying system of the whole stalk sugarcane harvester or cut-off sugarcane harvester used in the market is mainly to push the sugarcane to a certain angle through the front corrugated cane pressing roller, and then the double cutter disc cutter will push the sugarcane to a certain angle. After the sugarcane is cut, it is transported. To realize the backward transportation after the sugarcane is cut, it must be changed from the vertical direction to the horizontal direction. At this time, the sugarcane has been separated from the cane pressing roller. It is a passive feeding and conveying method to enter the next process; since the corrugated cane press roller has no diversion effect, the sugarcane will gather in the center of the cane press roller during the process of being pushed down, and the gathered sugarcane leaves will be entangled with each other. At the same time, sugarcane and sugarcane will also hinder each other's movement.

The entire cutting system is usually integrated with the subsequent leaf stripping system (cutting system). In order to adapt to different ridge heights and cut normally, the cutting system and the subsequent leaf stripping (cutting) system must be lifted at the same time. Since the cutting system is integrated with the subsequent leaf stripping (cutting) system, the vibration of the leaf stripping (cutting) system will be transmitted to the cutting system during work, which will cause the vibration of the entire cutting system to intensify, resulting in the sugarcane head breaking rate when the harvester is working. It remains high; the distance between the clamping and feeding ports of the cutting system is relatively fixed, and when the harvester encounters sugarcane with a thicker diameter or multiple sugarcanes gathered at the clamping and feeding port at the same time, the capacity is blocked.
