[0002] In agricultural production, labor costs account for a large proportion. With the development of the economy and the improvement of people's living standards, a large number of rural laborers have moved to cities, and the problem of agricultural labor shortage has become increasingly prominent. At the same time, manual harvesting of corn requires a lot of manpower input and has low work efficiency, resulting in rising labor costs. The use of mechanized equipment such as corn root cutting devices can effectively reduce dependence on manual labor and reduce labor costs. For example, a modern corn harvester equipped with an efficient root cutting device can complete the harvesting and root cutting of a large amount of corn in a short time. Its efficiency is much higher than manual harvesting, which can not only save labor costs, but also alleviate the pressure of agricultural labor shortage, allowing farmers to complete corn harvesting operations more easily.

[0003] However, in the process of harvesting corn, existing harvesters often cut the corn stalks at the roots on the soil surface to harvest the corn in a regular manner. The corn roots buried under the soil need to be loosened and removed by special loosening machinery. This cycle repeats many times to completely remove the corn roots, which is inefficient.

[0004] Therefore, we provide a corn root cutting device for corn harvesting to solve the above problems. Utility Model Content
