Description

Technical Field

[0001] The utility model relates to the technical field of corn harvesting equipment, in particular to a fresh corn harvesting header. Background Art

[0002] In recent years, with people's preference for fresh corn, the planting area of ​​fresh corn has continued to expand, which has promoted the development of mechanization of fresh corn harvesting. Many mechanical products related to fresh corn harvesting have appeared on the market. Such products mainly use horizontal roller ear picking devices, plate ear picking devices and vertical roller ear picking devices for ear picking. However, fresh corn has a higher moisture content than traditional corn. The existing harvesting method can easily cause grain damage. According to actual harvesting conditions, it is generally difficult for the ear picking device to directly break the ear stalk but breaks it at the straw. The broken straw will increase the power consumption of the machine and easily clog the machine to cause grain damage, thereby affecting the quality of ear picking. Utility Model Content

[0003] The utility model aims to provide a fresh corn harvesting cutting platform, which adopts an upward pulling stem type to simulate manual pulling downwards, has less impact on the ears, and is convenient for subsequent processing of the corn plants.
