Description

A Windrower Adapting to Crops of Different Plant Heights

technical field

The utility model relates to the technical field of agricultural equipment, in particular to a windrowing machine adapted to crops with different plant heights.

Background technique

The growth of crops is affected by the external environment. Under different conditions such as temperature, precipitation, and light, the growth of the same crop and the yield at harvest are very different, especially in areas with harsh climates such as the Northwest Mountains. The harvest of crops in different years is not the same. In the stage of crop harvesting, due to the terrain, it is difficult for the combine harvester with high operating efficiency to work on land with large terrain differences such as mountains. This is to a large extent The development of intensive agricultural mechanization in these areas is restricted. At the same time, such an environment also gives room for the development of other small agricultural machinery; the windrower used for segmental harvesting is one of them, and the windrower satisfies the requirements to a certain extent. However, the crops planted in the mountains are greatly affected by environmental factors, so the growth conditions of the crops are different; although the existing windrowers can basically meet the requirements for harvesting the crops planted in the mountains. However, for some crops with relatively high growth height, the adaptability of the windrower is not very good. During the transfer process, the stress on the crop stalks is unbalanced, resulting in a relatively loose laying of the crops, which has caused great trouble to the subsequent collection.
