If you are a farmer then you must be aware that how making small adjustments can bring a good chance in the overall performance. Performance of a machine can go unpredictable in the field if some required adjustments in the concave combine harvester are not done. It is the system which starts with the header and no component works independently and it ends at planter. Straw chopper, cleaning fan, thresher, feeder house, separator etc. interact with one another with an effect. Many experts believe that combine is a very sophisticated machine and it helps in doing a lot of tasks at one time.

The Endless Routine of Combine Offers:

• Threshing of crop

• Separating the grain

• Dispersing the residue

All the processes function smoothly with one another smoothly to achieve optimum performance.

Interaction Influences Combine Performance

The header and feeder houses of the concave combine harvester are the first point of contact. They are responsible for moving the crop into the combine. The performance of the combine gets influenced in particular with soybean platform and small grains. The thriving capabilities of the combine depend on the smooth feeding of the crop in the machine. If you are doing the bunch feeding and there is a mis adjustment in the reels on the platform, it dramatically increases the grain damage.

In concave combine harvester, feeder houses are considered more than a simple conveyor between the combine and the header. The in flowing crops get flattened by the feeder house drum and conveyor chain. This helps in preparing them for smooth feeding in the separator. The majority of crops travels in the center third and this leads to a decrease in the efficiency of feeder house.

Other Processes of a Combine

In the concave combine harvester, the threshing segment follows the rubbing action between the surface of the concave and threshing lobes or rasp bars. This could knock kernels from the cobs, seeds from the seed head etc. If too tight then grain gets crushed and if too fast, the grain gets cracked. The optimum threshing speed and concave clearance for a particular crop are mentioned in the owner’s manual and also some specifics about the moisture.

The separate section of the concave combine harvester is the combination of upper and lower sieve, cleaning fan etc. The residue and mat of grain float across the sieves due to shaking motion so that grains can fall down through it and through the residue as well. If all the cleaning is done through the lower sieve because some farmers think this can keep the grain from going out the back. The issue is that the bottom sieve gets overloaded and tailing return. The upper sieve does the main separating and the lower sieve is for the fine-tuning of the sample.

Secondary to threshing and separation of grains come stalk choppers. The residue management hast turned into a critical function due to the improved genetics of small grain which is combined with reduced or no-till practices.
