PURPOSE:To enable the uniform supply of a particulate material, by allowing a large number of gathering branch pipes, which are attached to the gathering base pipe erected in a silo in an upwardly oblique state to communicate with each other while taking the particulate material, into the gathering base pipe from a large number of positions in the silo through the gathering branch pipes. CONSTITUTION:In a gathering pipe wherein the arbitrary numbers of many gathering branch pipes 3 are attached to the gathering base pipe 4 erected in a silo 1 in an upwardly oblique state, throttled cylindrical parts 5 of which the diameters are gradually reduced toward the lower side are provided in the gathering base pipe 4. The communication mouth part of each gathering branch pipe 3 is positioned to the wall surface of the base pipe faced to the gap between each throttled cylindrical part 5 and the inner wall of the base pipe 4. That is, a particulate material is taken in the gathering base pipe 4 from a large number positions in the silo through the arbitrary numbers of many gathering branch pipes to enable the uniform supply of the particulate material. |
