The modern combine harvester, frequently referred to as a combine, is adaptable equipment that can successfully harvest a variety of grain crops. It combines the four distinct harvesting processes of reaping, threshing, gathering, and winnowing into a single procedure, hence the name. Among the crops gathered using a combine are wheat, rice, oats, rye, barley, corn (maize), sorghum, soybeans, flax (linseed), sunflowers, and seed. The crop’s stems and any remaining, low-nutrient leaves make up the separated straw, which is left on the field and cut, scattered, plowed back in, or baled for bedding and low-deed for cattle. One of the most economically significant labor-saving innovations is the combine harvester, which has significantly decreased the number of people working in agriculture.
A removable header intended for certain crops is mounted on combines. The typical header, which is also referred to as a grain platform, contains a reciprocating knife cutter bar and a rotating reel with metal teeth that cause the chopped crop to fall into the auger when it is cut. When cutting soybeans with pods that have fallen to the ground, a “flex” platform, which is similar to the regular platform, features a cutter bar that can flex across ridges and hills. Although a rigid platform is frequently used solely for cereal grains, a flex head may cut both soybeans and cereal crops.
Some wheat headers, referred to as “dr” headers, use a fabric or rubber apron in place of a cross auger. Dr headers have fewer power requirements than cross augers, which enables faster feeding and larger throughputs. ᴍᴀɴy farmers cut wheat with platform headers rather than separate wheat headers to save money. Dummy heads, often referred to as pick-up headers, have pickups with spring-tines that are typically fastened to a thick rubber belt. They employ crops that have already been chopped and arranged in swaths or windrows. Weeds can be dried out more quickly by swathing, which is crucial in northern regions like western Cᴀɴᴀᴅᴀ.
Although corn can be planted on a grain platform, it is typically done using a customized corn head. Only the ear of the corn can enter the throat because snap rolls on the corn head tear the stalk and leaf from the ear. Efficiency greatly increases because there is less material that needs to pass through the cylinder. urmari urmari urmari urmari dispozitie dispozitie cerinte clientilor dispozitie dispozitie desfaso desfaso desfaso desfaso desfaso desfaso desfasopoți desfasotoatasectiunesectiunesectiunesectiunesectiunesectiuneăci dispozitie dispozitie dispozitie dispozitie dispozitie On rare occasions, row crop heads that look like corn heads and serve as a grain platform but have points between the rows can be noticed.
