PURPOSE:To greatly improve the durability and safety of the curved part of a pipe, by providing a funnel-shaped receiving plate which is secured in a central expanded portion having an inlet section and an outlet section and faces the inlet section. CONSTITUTION:A funnel-shaped receiving plate 12 is secured in a central expanded portion 10 having an inlet section 6 and an outlet section 7 and faces the inlet section so that grains straightly flowing in collide very little directly against the inside surface of a curved pipe 3 and the high-power flowing-in part of the grains collides mostly against the funnel-shaped receiving plate 12. The impact of the grains on the pipe 3 is thus decreased so that they are conveyed as their flowing power is reduced. Therefore, the durability and safety of the curved part of the pipe are greatly improved. Since the constitution is simple, the cost of manufacturing is low and the assembly and disassembly are easy. |
