摘要

以提高采摘后红花丝收集效率和采收质量为目标,优化设计便携对辊式红花采收机采摘腔室内的气流场,基于Fluent流体仿真软件建立了红花采收机气固两相流分布模型,根据实测的红花采收机相关数据,确定边界条件和模型参数,得到不同导流孔参数下气流场分布.设计了与模拟条件相同的验证试验,利用高速摄像与试验设备对仿真结果进行验证分析,试验结论与仿真结果均表明:红花采摘腔室的较佳参数为导流孔直径d=6 mm、导流孔数量N=3、导流孔排列方式为竖向、导流孔间距h=15 mm,在此参数下采摘腔室内气流场流速稳定,花丝运动轨迹较为一致,花丝收集效率较高.

Abstract

To improve the collection efficiency and quality of safflower silk after picking, the airflow field in the picking chamber of portable counter roller safflower harvester was optimized. The relationship between the diversion holes in the picking chamber of safflower harvester and the trajectory of safflower filaments was investigated, and a gassolid twophase flow distribution model of the safflower harvester was established based on the Fluent fluid simulation software. The boundary conditions and the model parameters were determined based on the measured data of safflower harvester,and the distributions of airflow field under different parameters of diversion holes were obtained. The verification test under the same conditions as the simulation was designed, and the highspeed camera and the test equipment were used to verify and analyze the simulation results. The test conclusions and simulation results show that the preferred parameters of the safflower picking chamber are determined with  diversion hole diameter of 6 mm, diversion hole number of 3, vertical diversion hole arrangement and distance between the diversion holes of 15 mm. For the preferred parameters, the flow velocity of airflow field in the picking chamber is stable, and the filament trajectory is relatively consistent with high filament collection efficiency.
