In the case of this kind of threshing machine installed in combine harvesters, harvesters, etc., third materials such as straw waste are discharged from the suction impeller chamber located at the end of the main sorting air path of the threshing machine. The amount of grain that gets mixed into the third straw waste and is discharged outside the machine, that is, the amount of grain that is scattered by the third grain, depends on the moisture content of the grain culm being threshed. This is especially true in grain culms with low moisture content, and when harvesting and threshing standing grain culms wet with morning dew or rain, or grains with high moisture content such as lodging grain culms that have fallen in the field. It tends to increase in culm conditions.

ことができる。 Therefore, when harvesting and threshing standing grain culms wet with morning dew or rain-wetted standing grain culms with high moisture content, or grain culms with high moisture content such as grain culms that have fallen in the field, it is difficult to remove grains with high moisture content. In the case of threshing conditions that increase the number of grains, by connecting the third grain collecting device 40 to the end of the third discharge tube 30 of the threshing machine 1, the grains are blown out along with the wind via the suction impeller chamber 31. The centrifugal force of the rotating spiral blades 32 allows the third grain to be transported backwards while being diffused toward the surrounding sorting net 34, and by this diffusion transfer, the grains pass through the mesh of the sorting net 34. The straw waste that does not pass through the mesh can be transferred to the rear and discharged outside the machine through the waste discharge port 39 from the discharging blade 35 at the end. It is possible to collect the third scattered grains that increase when threshing grain culms.

It has the advantage that it can be easily removed when it is not needed, such as when threshing grain culms that normally have a low moisture content and few scattered grains.
