How do you reduce Combine tailings?

How do you reduce Combine tailings?

Proper rotor speed , concave clearance, fan setting and sieve adjustment will reduce the amount of tailings. Tailings should include only unthreshed particles.

What are two adjustments that affect threshing action?

Threshing Losses Factors influencing this process include: 1. Crop conditions, such as moisture and variety, will affect how easily kernels thresh. 2. Speed of the cylinder or rotor.

What is the difference between a chaffer and sieve?

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.

What are tailings on a combine?

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 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. When the grain tank is full, a tractor with a grain cart on the back pulls alongside the combine.

What could be the most important adjustment in reducing the loss for a rice combine harvester?

Fine tuning forward speed and header height is especially important to minimize field loss.

How do you set combined sieves?

The front third of the upper sieve should be completely clean. The middle section should carry a mixture of grain and crop residue. The rear third should carry only trash. If the sieve is totally covered, increase the fan speed.

What do Concaves do in 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.

What is a chaffer on a combine?

Trapped within this mixture, and making up the other half of it, is the grain you want to save. The HARVEST Air Foil Chaffer provides a uniform distribution of air across the entire width of the combine. It also redirects the air almost straight up. This uniform blast of air prevents the matting which traps your grain.
