How can rice and wheat thresher improve threshing efficiency and reduce food loss?
Publish Time: 2025-03-27
As an important part of modern agricultural machinery, rice and wheat thresher is of great significance to improving agricultural production efficiency and reducing farmers' labor intensity. However, in actual operation, how to improve threshing efficiency and reduce food loss has always been the focus of farmers and agricultural machinery manufacturers.
1. Strategies to improve threshing efficiency
Adopt advanced technology design: Modern rice and wheat thresher generally adopts advanced threshing devices and power systems, such as the new rice and wheat thresher of Saint Lu. By optimizing the design of threshing drum and threshing gap, it ensures that the high-speed rotating threshing drum can effectively and quickly separate rice or wheat, thereby improving threshing efficiency.
Adjust the speed of the threshing device: Properly increasing the speed of the threshing device is the key to improving threshing efficiency. However, it should be noted that excessively high speed may lead to increased mechanical wear and increased food loss, so it should be reasonably adjusted according to the type of crop and actual situation.
Optimize grain feed: Ensuring that the grain feed is normal and not too large helps the thresher maintain a stable working state and avoids blockage and incomplete threshing caused by excessive feed.
Enhance machine adaptability: The structure of rice and wheat thresher should be compact and easy to move to meet the needs of different working environments. For example, a foldable design is adopted to facilitate flexible use in the field and reduce transportation time and cost.
2. Methods to reduce grain loss
Adjust the threshing gap: The size of the threshing gap directly affects the threshing effect and grain loss. If the gap is too large, the threshing is not clean; if the gap is too small, it may cause grain damage. Therefore, it should be adjusted appropriately according to the crop type and humidity.
Replace worn parts in time: The threshing parts of the thresher, such as drums and screens, will gradually wear out during use, affecting the threshing effect and grain loss. Regular inspection and timely replacement of worn parts are effective measures to reduce grain losses.
Reasonable drying of grains: Proper drying of grains to ensure that they have appropriate dryness and humidity during threshing helps reduce damage and loss during threshing. Overly wet or overly dry grains are not conducive to threshing. Optimize the use of separation screens and fans: Blockage of the separation screen holes and improper fan speed are one of the main causes of grain loss. Regularly cleaning the screen holes and adjusting the fan speed and angle according to the type and humidity of the grain can effectively reduce grain losses.
Avoid blockage during threshing: Too much thickness when feeding grains, wet straw and too long straw entering the thresher may cause blockage. Therefore, the thickness and uniformity of grain feeding should be ensured to avoid feeding too wet and too long straw into the thresher.
Improving the threshing efficiency of rice and wheat thresher and reducing grain losses are important directions for the development of modern agricultural machinery. The threshing efficiency can be effectively improved by adopting advanced technology design, adjusting the speed of the threshing device, optimizing the grain feeding amount, and enhancing the adaptability of the machine. At the same time, by adjusting the threshing gap, timely replacing wear parts, reasonably drying grains, optimizing the use of separation screens and fans, and avoiding blockage during threshing, grain losses can be significantly reduced.
