Composite Device for New Grain Transportation Separation and Cleaning
Journal Title: 河南科技大学学报（自然科学版） - Year 2017, Vol 38, Issue 1
Abstract
In view of the problems of large volume and strong vibration in small grain combine harvester cleaning system,a new type of composite device for grain transpotation,seperation and cleaning was developed.The device was combined with the spiral conveyor,sieve separation,air cleaning and so on. The device had small size and weak vibration. The process of conveying grain mixture for effectively separating stalks was realized by cutting stem processing. The cleaning ability of the device was improved. Through indoor experiment,the optimal working parameters of the composite device were obtained. Under the optimal parameters,the composite device grain crushing rate is 0. 27%,cleaning loss rate is 0. 18%,entrainment loss rate is 0. 45%,the cleaning rate is higher than 98%,and the cleaning ability is 977. 4 kg/h.
