Abstract:At the simulation platform of DFQX-3 air-and-screen cleaning device, the velocity of flow at different positions of the vibration sieve surface was measured through the space-points. With the measurement, the velocity of flow in the surface is less than 4.81m/s which is low-speed airflow. We used Matlab to plot the isovel and velocity variation curve of the cross section, vertical section and horizontal section at different positions in the screen surface, and then analyzed the distribution rules of the velocity of flow on the screen surface of the air-and-screen cleaning device. The result shows that the velocity of flow is symmetric on both sides of the screen surface, and is close at both ends while complex in the middle. |
Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
