Determination of Rice Grain Physical Properties
摘要
Abstract
The demand of the design and production of the agricultural machinery promotes development of agricultural materials properties testing and research with the rapid development of agricultural machinery .Rice grain physical proper-ties and mechanization of rice production is closely related , such as seeding technique , direct seeding , raise seeding and transplanting techniques and threshing-cleaning technology .This paper studied the physical properties of rice grain , in-cluding:grain geometrical size , density , coefficient of internal friction , coefficient of sliding friction between the plate and the rice grain , recovery coefficient between the plate and the rice grain and rice grain suspension speed .Test results provide a reasonable and reliable design basis for design on rice mechanical production and the original physical parame -ters for related to numerical simulation .关键词
