中文摘要:采用二次正交旋转组合试验方法,取脱粒滚筒线速度、风口真空压强、果穗含水率为影响因素,破碎率、含杂率、未脱净率、吸杂误夹种率为目标函数,对影响玉米种子脱粒效果的部件尺寸和作业参数进行了试验验证和优化设计。试验分析得出:当脱粒滚筒线速度4.6~5.5m/s、果穗含水率14.4%~15.9%、风口真空压强为6.3MPa时,含杂率低于 1.1%,破碎率低于 0.86%,未脱净率低于1.1%,吸杂误夹种率低于 0.44%。该试验研究可应用于立式轴流玉米单穗种子脱粒机的产品优化设计和作业参数选择。

Abstract:Three structure and operation parameters which had effect on vertical axial-flow corn single panicle thresher were optimized. The quadratic rotary orthogonal experiments were carried out. Taking linear velocity of threshing cylinder, negative pressure value of fan, moisture content of cluster as effect factors, and broken rate, impurities, loss of entrapped grains, gettering drift loss as objective function, the structure size and operation parameters were experimented and optimized design. The result showed that when the linear velocity of threshing cylinder was 4.6~5.5m/s, the moisture content of cluster was 14.4%~15.9%, the negative pressure value of fan was 6.3MPa, the broken rate was less than 1.1%, impurities rate was less than 0.86%, loss rate of entrapped grains was less than 1.1%, and gettering drift loss rate was less than 0.44%. This experiment’s analysis could provide theory basis for the optimization design and operation parameter selection for the vertical axial single panicle threshing corn product.

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.
