Chute pipe for particle transportation

The invention provides a chute pipe that can easily transport and distribute particles. The chute pipe for particle transportation has: a loading chute pipe (10) that has a loading port (11) for particles; a discharge chute pipe (35); and an intermediate chute pipe (20) that diagonally connects between the loading chute pipe (10) and the discharge chute pipe (35). The intermediate chute pipe (20) has a groove (23) not having steps and being formed from the combination of a first inclined plane (21) and a second inclined plane (22). The groove (23) has a cross-section in the shape of two adjacent sides of a triangle. 本发明提供容易进行颗粒的输送和分配的滑槽管。颗粒输送用滑槽管包括：具有颗粒的投入口（11）的投入用滑槽管（10）；排出用滑槽管（35）；以及倾斜连接在投入用滑槽管（10）与排出用滑槽管（35）之间的中间滑槽管（20），中间滑槽管（20）具有由第1倾斜面（21）和第2倾斜面（22）的组合形成的无台阶的槽（23），槽（23）的截面形状是相当于三角形的相邻两边的形状。
