| 4. | Abstract : stripper header invented by afrc uk , mounted on grain combine harvester showed its two deficiencies in china : leaving the stripped straw stan ding without windrowing and relatively high free grain loss especially working a t lower ground speed 文摘:英国发明的悬挂在联收机上的摘脱台在中国使用中有两个缺点:摘脱后的基秆未能切割搂集成条铺和落粒损失,尤其在低速时较大。 |
| 5. | Through the experimental analysis of the single factor , the influence of the rotation speed of the two kinds cross - flow fan and the forward speed was find on grain losses of the unit , finally the optimum combination of the forward speed and the rotation speed was got 通过单因素的实验分析,找出在横流风机不同风机转速,不同的行车速度下摘脱装置落粒损失的变化规律,并确定了最佳的装置参数组合。 |
| 6. | The pneumatic performance of the fan was got when working at several different rotation speeds based on the similar theory , which is useful to estimate the pneumatic performance of the fan when the air flow of the fan changes , and further the grain loss of the unit can be estimated 由装置出风口的气流流量,通过特性曲线来求解出风机该状态下的其他性能系数,分析此情况下的风机性能对装置落粒损失的影响因素。 |
| 7. | Hello , restrain in marrow period it is to should avoid to affect , had done nurse measure , if luck is white , can use the remedy with white hurried namely again , indigestion fall bead cell stimulates factor to wait , also can undertake recuperating with chinese traditional medicine , be in commonly stop 10 days of or so marrow after changing cure to begin to restore , need not too anxious 你好,在骨髓抑制期一是要避免感染,做好护理措施,再就是可以应用促白的药物如瑞白、积落粒细胞刺激因子等,也可以用中药进行调理,一般在停化疗后10天左右骨髓就开始恢复,不必过于着急。 |
| 8. | The air - flow field in the stripping unit can be adjusted easy by changing the rotation speed of fan which is benefit to reduce the grain losses , it was found during experiment that the cross - flow fan can diffuse some of mog ( material other of grain ) and diffuse it in a certain direction which is useful to satisfy the working condition for driver and lighten working load of the threshing unit of the combine harvester candidate and speciality : peng shengmin ; machinary design and theory supervisor : prof . zhang huiyou 该装置可以通过控制横流风机的转速,使装置内气流在有控制的情况下排出装置外,改善了装置内流场状态,提高了装置喂入口处的负压,这对减少摘脱装置的落粒损失,有着重要意义。由于横流风机的除杂,可以减轻机器的复脱和清选负荷。安装横流风机后可以对装置的出风口处灰尘进行有效导引,改善驾驶员的工作条件。 |
| 9. | 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 针对非气吸式割前摘脱装置在收获作物时,出风口筛面发生堵塞使装置内流场变差,导致装置的落粒损失率过大;以及出风口处烟尘四散,影响了驾驶员的视野和危害工作人员的身心健康等生产中存在的问题。 |
