Working Conditions And Structure Parameters Research On Cyclone Separating Cleaning System Of Micro-combine Grain

Cyclone Separating Cleaning System, which is cleaning device very concerned inrecent years,,mainly consists of winnower,grain pipeline, Cyclone Separating Cone,fan and is small volume, simple structure and efficiency separation ability. This papermainly studied the different structure and working conditions of Cyclone SeparatingCleaning System in order to solve the problems that existing in the Cleaning System of4L-0.2Micro-sized grain Combine such as: fan high speed, wet material jams in thesystem, long stem separation difficult, big volume, the connection angle betweenpipeline in winnower and cyclone separating cone.In this paper, according to the actual application situation that Cyclone SeparatingCleaning System is used in Micro-sized grain Combine, we made an experimentalresearch about Cyclone Separating Cleaning System to provide the reference forsolving the problem of the system. Using Cyclone Separating Cleaning System test-bed, High-speed camera instrument, based on normal working condition of material inthe clearing system, we discussed the motion law of material components insideCyclone separator on the case of changing rotating peed of winnower and moisturecontent of material. Through the analysis of the various components of the material inthe motion law of the different working conditions, we get the primary influence factorof motion state and track in the material components.Combineing with the aboveexperiment results, we had a single factor test about the Cleaning rate and Losing rateof the system as entrance angle and vents up in the the Cyclone separator, speed of fanand winnower for test factors and get clear choose performance test rule. Finally,wemeasured the speed of the export in the Cyclone Separating Cone with the vent air ornot and get its distribution rule.
