A stripping uint with the cross - flow fan was developed , aimed to reduce the grain losses at the rear of the stripping drum reduce the blocking to the air outlet sifter and diffuse dust . . this dissertation gives overall scheme of the rig and had mad experimental study 針對非氣吸式割前摘脫裝置在收獲作物時,出風口篩面發生堵塞使裝置內流場變差,導致裝置的落粒損失率過大;以及出風口處煙塵四散,影響了駕駛員的視野和危害工作人員的身心健康等生產中存在的問題。

In order to solve the technological problem of the dredge of raw material flow on the production line , we ? e carried out as overall theoretical and experimental research on the movement characteristic of the raw material on the surface of sifter in the vibratory machine , the dynamics property of the vibration stimulated by inertial double - axes , the flow property of raw material in these store hoppers , the agglomeration and obstruction mechanism 針對生產實踐急需,提出了本項研究題目。本文為了解決生產線物料流疏通的技術難題,對物料在振動篩分機篩面上的運動特性、雙軸慣性激勵式振動篩分機的動力學特性、儲料倉內物料的流動特性、物料結拱及堵塞機理等進行了全面的理論分析和試驗研究。

Through investigation and comparison of the edition , sifters have found that the present : yu zhang series has been of the same origin with the series corrected by yu wangjue , which exists little differences , and it had no original connection with the series of ye zhanquan , which exists much differences 通過版本考察與對比,整理者發現行世《豫章叢書》本與館藏俞王爵校輯本同源,差異較小,而與館藏清初葉瞻泉刻本無淵源關系,差異較大。
