What does the concave do on a combine?
The combine concave performs two important functions- threshing and separating. The threshing process frees the seeds from the plants. Then the separation process moves the seeds away from the chaff.
Where is the chaffer on a combine?
We refer to the top sieve as the chaffer and the bottom as the shoe. Top screen and bottom screen here.
What are combine tailings?
The tailings return system is intended to take crop material that is not completely threshed and/or not completely cleaned from the combine cleaning shoe back to the main threshing cylinder. The combine could be simplified and reduced in cost.
How does a combine work?
The Anatomy of a Combine
- The header cuts off the plant close to the ground and moves the whole plant into the machine.
- The cut crops move toward the center via spinning augers and travel up a conveyor.
- The threshing segment of the combine beats the cut crops to break and shake the grains away from their stalks.
What is the difference between a sieve and a chaffer?
is that sieve is a device to , in a granular material, larger particles from smaller ones, or to separate solid objects from a liquid while chaffer is bargaining; merchandise or chaffer can be (agriculture) the upper sieve of a cleaning shoe in a combine harvester, where chaff is removed.
How does a combine get the corn off the cob?
Each stalk has only one or two cobs of corn, depending on its genetic makeup. The head of the combine pushes through the corn field and grabs the stalks from the ground. The stalk is then forced through a small area where the corn cob pops off, along with much of the husks. Chains then push those cobs into the combine.
Why is it important to adjust combine settings for soybeans?
Proper combine settings and attention to detail during soybean harvest reduces harvest losses. Short soybeans are especially difficult to feed into the header and through the combine header because they are often podded lower to the ground, which increases the risk of loss.
What are the maintenance troublespots on a combine?
Maintenance troublespots Particular wear points on a combine that often demand attention are any parts experiencing repeated friction, like the roller chains on a corn head. With any chain that has noticeably loosened, stretched, or become “sloppy,” the likelihood that part will last through harvest’s end lessens.
How often should you stop the Combine in the field?
Other general rules to adjusting in the field include: Check the combine’s performance frequently and particularly when field conditions (such as grain moisture content) or varieties (especially with corn) change. Stop the combine at least once a day in an area representative of the field.
When to do a check load on a Deere combine?
Recalibrating monitors should be done at the start of every harvest season, possibly even during the season, notes Deere’s Hawk. “You might want to do a check load, for example, to double-check calibration during the season,” he says. “With so much technology in the combines, we typically have a yearly inspection done by the dealer.
