John Deere combine concaves are combine parts that are used in the harvester. These concaves are parts manufactured by the internationally renowned John Deere Company. The harvester is one of the most important types of equipment that a farmer can use to make his work easier. It helps to automate the process of harvesting, allowing processes like threshing and winnowing to be done using the equipment. This ensures a reduction in effort and time for the farmer, thanks to mechanization.
All about combine concaves
John Deere combine concaves are key parts used in the combine harvester. The combine harvester has a reel at the front that does the key activity of pulling the grain stalk and then pushing it into the machine. Once the grain stalks enter the harvester, a conveyer belt moves the stalks into the threshing cylinder. The threshing cylinder rotates over the concave at a high speed. When this happens, the kernels and the stalk heads are separated.
Once this is done, the kernels would be collected in a grain pan. The kernels after separation fall into slits on the concave to reach the grain pain. The stalk heads are separated. The grain pain starts vibrating and this process removes chaff and other materials, which are taken out from this compartment. Finally, the cleaned grain kernels are separated and they are moved into the grain tank. This is how the process of harvesting works in a combine harvester.
From this description of the process, you would have understood the role played by John combine concaves. They are an essential part of the harvester, which helps in threshing and separating. The concave helps to remove the grains and separate them from the stalk. During the separation process, chaff is removed from the grains and the harvested grains and stored in the tank. For all these to work, the concave part should be of good quality.
Handling the concave
John combine concaves would have a space between the concave and the cylinder. This space is what allows the materials to move smoothly. Setting this space is important. There are other such settings that need to be done to ensure that the concave works perfectly in the harvester. If space is not set properly, then the stalk gets damaged. If too much space is given, then separation does not happen in an effective way.
You can use different concaves for different crops harvested. For instance, if you are harvesting corns then the seeds are large and they require more space to fall into the tank. Hence, you need concaves with wide wires. If you are harvesting a crop like wheat, then the grains being small require slits that are narrow, so you need a narrow wire concave.
You can choose the concave type of your choice depending on the crops that you want to harvest. The concave settings can also be fine-tuned, so that the harvester works with precision. The combine concaves thus play a key role in the harvesting process.
