[0002] Grain warehouse is an important facility for modern agricultural production and grain storage, aiming to ensure the safe storage and efficient management of grain after harvesting. With the progress of agricultural technology and management concept, the design and function of grain warehouse are continuously optimized. Especially in the process of grain warehouse, grain is transported from the inside of the warehouse to the truck through the grain outlet pipeline. Usually, it is cleaned and screened first to ensure the quality of grain. During the grain outlet process, grain flows through the pipeline and is loaded into the truck in an orderly manner by gravity or mechanical conveying device, ensuring transportation efficiency.
[0003] During the process of grain loading, the grain outlet equipment often produces noise when transporting grain to the truck, which is mainly caused by the impact between grain and pipeline. The noise not only affects the surrounding environment, but also may affect the health of workers. Grain often carries a certain amount of dust during the transportation process. These dusts are raised with the movement of grain, causing dust to spread in the air, affecting air quality and potentially threatening the respiratory health of operators. It cannot meet the actual needs. SUMMARY
