Description

Whole pole sugarcane harvester

technical field

The utility model belongs to the field of agricultural machines, in particular to a whole pole type sugarcane harvester.

Background technique

Sugarcane harvesters are divided into two categories, one is the whole pole type, and the other is the section type. The above two types of harvesters have the following problems in the past harvesting work;

(1) The header cutter head of the harvester does not have good terrain imitation technology. The traditional sugarcane harvester has a terrain exploration wheel, which is only used to explore the bottom of the ditch near the root of the sugarcane, and does not harvest sugarcane according to the height of the sugarcane root on the top of the ridge. , cutting sugarcane can not accurately imitate the terrain according to the uneven ground on the sugarcane ridge, the bottom of the cutting sugarcane fluctuates, causing waste and affecting the germination of perennial roots.

(2) The cane supporter does not have accurate terrain imitation technology, and a lot of sugarcane will be missed in the process of lifting the sugarcane with severe lodging, which is one of the reasons for the reduction of sugarcane production, and the missed sugarcane needs to be harvested one by one. The sugarcane leaves reaped by the harvester are collected and loaded from the ground, which increases the labor intensity of farmers.

(3) Whole-rod sugarcane harvesters generally have the function of stripping leaves. Because of the structure of the stripper and the wear resistance of the material, the stripping material is placed in the belly of the harvester, and it is inconvenient to replace the stripping material. The leaf material has poor wear resistance, poor leaf stripping effect and too frequent replacement times, which increases the labor intensity of the driver.

(5) The design of the tip stripper of the sugarcane harvester is defective. It can only cut the tail tip of one side, and the tail tip of the sugarcane is uneven, which will easily cause waste if the tail tip is cut too deep, and will be deducted by the sugar factory if the cutting is too shallow. The miscellaneous is serious, and the tip stripper is as useless to the lodging sugarcane.

(6) The sugarcane self-propelled harvester is huge and expensive, which affects the ability of cooperatives and farmers to purchase. The performance of the sugarcane harvester is single. After the sugarcane harvesting work is over, the harvester is sealed up. Caused a waste of financial resources.

(7) The sugarcane with serious lodging will affect the driver's sight and increase the difficulty of harvesting. The side-mounted harvester can better solve this problem.

(8) The problem of sugarcane row spacing. Generally, wheeled or crawler-type sugarcane harvesters have the problem that the sugarcane row spacing does not match the wheel spacing of the harvester, which will compact the sugarcane field or crush the cane bag to a certain extent, affecting the germination of perennial sugarcane. Reduced sugarcane yields.

(9) Most of the traditional wheeled and tracked sugarcane harvesters are tall and heavy and cannot adapt to harvesting sugarcane in mountains and hills. Generally, sugarcane is only harvested in relatively flat paddy fields and dry fields with relatively flat terrain.
