The threshinc., operation in the threshin, , & part of head feedin-, type combine consists of the pulling and squeezin" action of ears of rice plant with the threshinla, tooth, the friction with a concave, and the other conditions. It is an object of this study to clear the threshing operation by the threshine teeth. The experimental device measurinc., the threshin-r force of a threshinc, tooth was made by using some parts of a commercial type head feeding combine. It is known from the past experiment that the threshinu operation changes accordine to the settine condition of threshina tooth(the inclination ancle, the lead m 'm C3 anclle, the settine ancle, the settine pitch, the rotatine pitch), so a threshine tooth measuring the threshine force is set on the threshina drum in this experiment. The threshing tooth is independent of the threshing drum, but rotates with the same rotating radius and speed of the threshing drum. The parameters of this study are the setting pitch, the rotati … More ne pitch, and the lead angle of threshing tooth. The measuring points are the bending, moment and the torsional moment of the threshing tooth measuring the threshing force, and the driving torque and the rotating speed of the threshing drum. The experiment was done by using a sheaf of rice plant(variety KINMAZE)with the weight of about 1kgf that is made by gathering 6 8 hills of rice plant. The measuring terms about the sheaf of rice plant are the total weight before and after passina the experimental device and the weight of ears that is threshed and dropped under the concave and the rear position of threshing drum, and the threshing rate and the cumulative threshing rate are calculated from these data.The following matters are found from the experimental results.1)The threshing tooth measuring the threshing force strikes a sheaf 6 times during a pass of the threshing drum.2)The time for a strike of the sheaf is from 0.01 to 0.02 second. This time depends on the rotating speed of threshing drum.3)The threshing force increases in case with set larger or smaller lead angle in comparison with the normal angle.4)The threshing rate by a pass increases with the inclination of lead angle.5)It is found that the influence of threshing tooth upon the threshing force increases by the threshing teeth that are in pre- or postpositions rather than the the threshing teeth that strike at the same time.

脱粒机和部分头部喂入式联合收割机的脱粒操作由稻穗与脱粒轮、齿的拉动和挤压作用、与凹面的摩擦等条件组成。本研究的目的是通过脱粒齿完成脱粒操作。该实验装置测量脱粒机的脱粒力，牙齿是用牙齿的某些部分制成的 商用型头部喂料联合收割机。从以往的实验中得知，脱粒操作是根据脱粒齿的脱粒情况（倾斜角、导程m'm C3齿、脱粒角、脱粒齿距、旋转齿距）而变化的，因此本实验在脱粒滚筒上设置了测量脱粒力的脱粒齿。脱粒齿独立于脱粒滚筒，但随脱粒滚筒一起旋转 脱粒滚筒的旋转半径和速度。本研究的参数为设定节距、旋转节距和脱粒齿的导程角。测量点是测量脱粒力的脱粒齿的弯曲、力矩和扭转力矩，以及脱粒滚筒的驱动扭矩和转速。该实验使用一束重量约为 1kgf是由6-8山稻草采集而成。稻穗经过实验装置前后的总重量和脱粒落入脱粒滚筒凹部和后部位置的穗的重量作为测量稻束的指标，根据这些数据计算出脱粒率和累计脱粒率。由实验结果发现以下几点： 1）脱粒齿测量脱粒力 在脱粒滚筒的一次通过过程中，撞击禾捆6次。2)撞击禾捆的时间为0.01至0.02秒。该时间取决于脱粒滚筒的转速。3）与正常角度相比，设置较大或较小的导程角时，脱粒力增大。4）每次通过的脱粒率随着导程角的倾斜度而增大。5）发现脱粒齿对脱粒效果的影响 脱粒力是通过位于前位置或后位置的脱粒齿而不是同时撞击的脱粒齿来增加的。少
