Currently, reciprocating cutting blades on the corn harvester use the triangle tip tooth type blades, which are widely used in rice and wheat harvesters. Using the rice and wheat harvester blade to cut corn stalks results in large cutting resistance, high energy consumption, and poor quality of stubble along with other issues.

A. The Ordinary Blade Used In The Harvester. Harvester blades are the elements of the combine that scrape the surface of crops such as wheat, barley, corn, and other grains [25]. Iron and steel are perhaps the most prevalent materials utilized in the production of these blades.

Existing corn harvester cutting blades have problems associated with large cutting resistance, high energy consumption, and poor cut quality. Using bionics principles, a bionic blade was designed by extracting the cutting tooth profile curve of the B. horsfieldi palate.

Harvester blades are the elements of the combine that scrape the surface of crops such as wheat, barley, corn, and other grains [25]. Iron and steel are perhaps the most prevalent materials utilized in the production of these blades. These blades are available from a variety of producers in the market, depending on the needs of their consumers.

A bionic blade was designed by extracting the cutting teeth profile curve of the beetle palate using bionics concepts. The analysis of designed bionic blade was carried out using Ansys software.
