Corn is one of the most important items in the development of agriculture in the country. Harvesting seed corn with a grain combine machine causes significant physical damage (10 to 15%) to the seed in the current conditions. The correct mechanism of seed production is the harvesting of corn cobs, after drying, the seeds can be separated from the cobs using a corn threshing machine. In this regard, the present device is used for the basic production of seeds, which seeds cobs with the least possible waste. The use of rubber for all surfaces in contact with the wings prevents any damage to the seed. Another major advantage of this device is its mobility, which gives the user the ability to move the device to the desired location before use.
