A telescopic discharge chute for bulk materials is described including telescoping first and second elongated tubular members. The first tubular member includes a first internal bore leading from a bulk material infeed at a first top end, to first bottom end. The second elongated tubular member includes a second top end and a bulk material discharge at a second bottom end. The second tubular member slides axially over the first tubular member between an extended position wherein the second tubular member projects axially downwardly from the first tubular member. At least one vent is formed by the second tubular member adjacent the second top end, opening outwardly and in open communication with the second internal bore. The vent is situated above the first bottom end of the first tubular member. The vent is included in a ventilation air passageway defined between the first and second tubular members. The passageway extends axially from an upper end in open communication with the vent to a lower discharge end in open communication with the first internal bore downwardly of the vent. Flanges on the first and second tubular members engage to prevent the second tubular member from sliding longitudinally off the bottom end of the first tubular member.
