Question

Combines are used for what?

Answer 1

Combines:

1. The combine harvester, sometimes known as the combine, is a device made to efficiently grow a variety of agricultural crops.
2. The word comes from combining three separate winnowing, threshing, and reaping processes into one.
3. A combine is a piece of equipment that recovers grain while also cutting standing crops.

Principle:

1. The primary mechanism of operation is the result of friction between the material and the threshing lobes or rasp bars.
2. The speed of the rotor and cylinder as well as the distance between the concave's surface and the threshing drum determine how effectively the rubbing motion works.
