INTRODUCTION TO TWIN ROTOR HARVESTING

There are four basic areas of harvesting:

Feeding Separation

Threshing Cleaning

Refer to Figure 1 to follow the flow of material through the combine.

FEEDING

The head cuts or picks the crop and feeds the cut crop to the auger, 1. The auger brings the crop to the center of the head, where it is fed into the front of the feeder, 2.

The crop is then carried up the feeder and fed into the rotors. The auger flighting on the front of each rotor, 3, feeds the crop across the feed plate, 4, into the threshing area. At this point, feeding is complete and threshing begins.

THRESHING

This process is carried out as the crop passes between the rotor rasp bars,S, and the con­caves, 6. As the rotors turn, they rub the crop against the concave rub bars and concave wires. This rubbing action threshes the grain from the straw. The rearward movement of the material between the rotors and the concaves is controlled, so the crop passes between the rasp bars and can caves several times. This allows for more efficient and complete threshing, with reduced risk of grain damage. The free grain falls through the concaves onto the grain pan, 7.

FIGURE 1

Chaff, straw and any remaining grain is moved rearward from the threshing area to the rotary separation area, by the action of the rotors tu rn­ing the material against the transport fins which are welded to the transport covers over the rotors.

ROTARY SEPARATION

When the material reaches the rotary separa­tion area, most of the remaining grain is separ­ated from the straw and chaff by centrifugal force.

The wires and bars of the separation grates, 8, allow only grain and chaff to fall onto the grain pan. Remaining material is forced into the discharge beater, 9, which also has a separation grate, 10, positioned under it.

Any remaining grain falls through this grate onto the chaffer sieve, 11, while the straw and remaining chaff is discharged to the rear of the machine. At this paint, separation is complete and cleaning begins.

IDENTIFICATION

Before operating your new combine. become familiar with the location and purposes of its controls and instruments. Study these pages carefully, regardless of your previous combine experience.

Your control levers and instruments have symbols to help you quickly locate them. Famil­iarize yourself with the symbols shown in Fig­ure 1 A so that you can identify the operation of the various controls and instruments. Figures 2 through 11 will help you identify the various controls.
