I figure I'll post some educationa lpictures of teh inside of a combine from the controls through the guts. One of teh guys I work for just traded this 2188 in on a new Case/IH 2588 but for the most part these axial flow combines are real similar:
Ok what you are seeing here is teh back part of the concave, your material is brought in through the front and there is a big rotor with rasp bars spinning inside the mesh looking screen above, this is where most of the threshing occurs and what drops onto those augers is drawn back to the sieves below (these are not shown yet).
Upper left you can still see part of the concave, good shot of the augers where they drop material to the sieves:
What doesn't pass through the concave is pushed into the chopper where it just beats the heck out of whatever is left over, then drops it to the sieves. The actual blades stikcing through that pan underneath are removeable 9se the next picture):
Me putting the chopper blades in. He does not run the chopper blades when doing corn and we were getting ready to harvest beans so we had to change a few things:
Here are the sieves, there are two big fans in the front of the combine that blow a large quantity of air through these to blow stuff out and let the grain drop through so it can be retained, the sieves are adjustable for different grains and they are not comfortable to lay on:
This simple looking doo-dad is a sensor that tells you in the cab how much grain is being lost out the back of the machine, it is mounted at the very rear of the combine where everything drops out and it lets grain drop on it and the impact sends a signal up front to a gauge. There isn't much making it out the back but you'll always loose some.
Inside the cab:
The yellow handle on the far right is the throttle, the two yellow knobs turn on the machine (back part) and the other turns the header on, both have to be on for the header to work. The transmission is hydrostatic and teh range selector is off to the right, forward backward motion is controlled by the big stick on the left. The knobs control the rotor speed, header float controls, all sorts of good stuff:
On the stick we have 4 buttons (left to right), the left big black button controls the reel position (in/out up/down), middle button controlls the header up or down and tilts it side to side, the right button controls the unloading auger to swing in or out to unload and the yellow button in the center is what engages the auger to unload:
Hope this helps somebody.
