Preliminary leaf knocking method and device for cane harvesting machine

Abstract

The invention provides a preliminary leaf knocking method for a cane harvesting machine. The characteristics of the vertical growth of cane tail portions, large cane toughness and the like whether the canes fall over or not are used, parts of the cane leaves are knocked off through a leaf knocking unit arranged on the front upper portion of the cane harvesting machine with a cane support unit, the canes are supported to be cut through the cane support unit of the cane harvesting machine after the leaves are knocked off, and accordingly, the cane harvest impurity rate is reduced, and the phenomenon of the incapability of normal harvest caused by blockage of the cane harvesting machine due to the dense cane leaves is prevented. By means of the method and a device, the impurity rate of cane harvest through the cane harvesting machine can be reduced, and the normal operation of the cane harvesting machine is guaranteed.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a method and device for prethreshing leaves of a sugarcane harvester. Background technique [0002] At present, the mechanization level of sugarcane production in my country is relatively low. The sugarcane harvesting work in domestic sugarcane planting areas is basically done manually, with high labor intensity, low efficiency, poor working environment, shortage of labor force and rising prices, which make sugarcane production mechanized. The need is very urgent. [0003] The steps of traditional artificial harvesting of sugarcane are: cutting down sugarcane-removing sugarcane leaves, sugarcane tips-sugarcane bundling. Harvesting sugarcane manually is labor-intensive and inefficient. Due to poor working environment and labor shortage, labor prices are increasing day by day, which also results in high cost of sugarcane planting and low profit. Therefore, people ha...

Problems solved by technology

Harvesting sugarcane with a segmented sugarcane harvester will cause a high rate of damage to the sugarcane, the loading tonnage is lower than 70% of the normal level, and the impurity rate is as high as 15%, and it requires two vehicles to cooperate with the harvest. The efficiency is low, and the sugarcane needs to be processed on the same day. The storage of sugarcane, sugarcane farmers, and drivers will be affected and lost to varying degrees. There is an urgent need for a sugarcane harvester with a whole pole harvesting. The traditional whole pole sugarcane harvester is very serious because the sugarcane lodging phenomenon is very serious, and the leaves of sugarcane It is dense, and it is easy to be blocked when the sugarcane enters the process of cutting, clamping and conveying, stripping and tailing, and cannot be harvested normally, and the cane leaves at the tail of the sugarcane are very tough, so it is difficult to strip the leaves when the sugarcane harvester is harvesting , the docked tail is not clean, resulting in high impurity content in sugarcane
