Reasons and Solutions of Impure Grain Discharging in Combined Harvesters
Introduction
The use of combined harvesters has been popularized in the agricultural industry around the world over the past few decades. It can complete the whole process of harvesting grain crops, including The use of combined harvester to complete harvesting processing. Harvesting grain crops involves the pressing, shelling and dehydration processes, which are usually carried out in succession. However, one of the common challenges faced by farmers is that the grain discharged from a combined harvester is often impure. This impurity may include unripe grain, foreign objects, husks, straw, and other debris. This can reduce the quality of the grain and result in reduced yields, thus reducing productivity and loss of income for farmers.
Reasons of Impurity
This problem of impure grain discharged from a combined harvester is mainly caused by inadequate cleaning during the process of shelling and dehydration. If the header is not clean, the header will not be able to remove all the husks, straw, stones, and other debris from the grain. This will ultimately lead to the impure grain caught in the combines. Moreover, sometimes, the speed of the combine may be too slow which will also lead to unripe grain or debris being in the combine. The husks may also be dried and become tougher over time, which makes it more difficult for the combines to remove them. Furthermore, the harvester may not be properly maintained. If the blades and rollers of the harvester are not sharp enough, they may not be able to effectively remove the debris from the grain.
Solution
To solve the problem of impure grain discharged from the combine harvester, it is important to ensure that the machine is properly maintained. The blades and rollers of the harvester should be kept sharp and clean and should be replaced with new ones as needed. This will ensure the efficient removal of all the husks, straw, stones and other debris from the grain. In addition, it is important to make sure that the speed at which the combine is running is at the optimal speed for harvesting. This speed should be adjusted according to the harvesting conditions of the grain.
Furthermore, in order to reduce the incidence of impure grain discharged from the combined harvester, the farmers should use a grain cleaner. This machine can effectively remove the husks, straw, stones and other debris from the grain by passing it through a series of screens. This will significantly reduce the amount of impure grain that is discharged from the combine harvester.
Conclusion
The higher level of impurity in the grain discharged from the combined harvester is a serious problem faced by the farmers. This problem can lead to reduced yields, thus reducing the productivity and income of the farmers. To solve this problem, it is important to maintain the combine harvester properly, adjust the speed of the combine for optimal harvesting, and use a grain cleaner. Following these strategies will help to minimize the level of impurity in the harvested grain.
