This study aimed to clarify the cleaning and separating characteristics of cleaner of a head feeding type combine. In 1998, in order to analyze the flow of the mixture of rough rice, chaff, and straw in the cleaning device of head feeding type combine, a small CCD-TV camera and a light source were built in the back side of grain shieve. It is not recognized the remainder of rough rice and chaff in case of the rated engine speed. In case that the engine speed decreased under 2000r.p.m., it is recognized the remainder of rough rice and chaff in the 2nd thrower. The wind velocity and the static pressure of fan were measured by a wind velocity meter with a thermal wire. When the engine speed was in the range of 1800〜2000(r.p.m.), the wind velocity on the grain shieve was in the range of 0.8〜13.3(m/s) and the static pressure of wind was in the range of 0.1〜0.4(mmAq).In 1999, the wind velocity and the wind direction were measured by a mold type wind velocity sensor at the center of cleaning chamber. It is clarified that the wind velocity was stronger at the edge of cleaning chamber. The main wind stream in the cleaning chamber shows the upward line with 45〜60 degrees. The wind velocity of the 2nd thrower is not uniform, and decreases at the center position of thrower.

本研究旨在阐明头喂入式联合收割机清选器的清选和分离特性。 1998年，为了分析头喂入式联合收割机清选装置中糙米、谷壳、秸秆混合物的流动情况，在粮仓后侧安装了小型CCD-TV摄像机和光源。在发动机额定转速的情况下，不识别剩余的糙米和谷壳。如果发动机转速降低到2000r.p.m以下，则识别出第二抛掷器中剩余的糙米和谷壳。风扇的风速和静压通过带有热线的风速计测量。当发动机转速在1800〜2000（r.p.m.）范围内时，粮耙上的风速在0.8〜13.3（m/s）范围内，风静压在0.1〜0.4（mmAq）范围内。1999年，通过清选室中心的模型风速传感器测量了风速和风向。说明清洗室边缘处风速较强。清洗室内主风流呈45〜60度的向上线。第二个投掷器的风速不均匀，在投掷器中心位置风速减小。
