Mechanization. Combine — harvesters

Combine harvesters are used to harvest various crops.

The combine harvester cuts the crop, threshes it, separates the grain from the

straw and chaff.

The mechanism of a combine harvester can be divided into three sections.

from the straw and chaff. To cut the crop a reciprocating tyre cutter bar is used.

The reel is one of the main parts of a

combine harvester.

It separates the crop to be cut

from that which will be left for the next round. The crop is cut while

held against the cutter bar by the reel. After the crop is cut, the reel di-

rects it to the cutter bar platform.

The reel is one of the main parts of a combine harvester.

It has tines which can be angled to provide better cutting of the crops. A large auger moves the crop to the centre of the platform.

By means of tines the auger directs the crop to the main elevator which

lifts the crop to the threshing mechanism.

The threshing mechanism consists of a front beater, a heavy rotating drum, and a rear beater.

The threshing mechanism consists of a front beater and a rear beater.

The threshing mechanism consists of a front beater, a heavy rotating drum, a concave, and a rear beater.

It consists of two sieves and a fan.

The separating unit is used to sort the grain and chaff on the grain pan.

The fan provides a flow of air to keep sieves clean.

The harvested grain is directed to the grain tank.

The fan provides a flow of air to keep sieves clean.

Grain tank capacities vary from 1 to 50 tonnes.

A high capacity auger is used to deliver the threshed grain from the grain into a trailer.

The harvested grain is directed to the grain tank. Big combines

have an auger in the grain tank to provide the proper flow of the grain.
