Chip conveyor

A chip conveyor comprising:

• a housing that has an inlet receiving chips and a discharge outlet for discharging the chips downward;
• and a conveying mechanism that is housed in the housing and configured to convey the chips received through the inlet toward the discharge outlet, the chip conveyor being configured to discharge the chips through the discharge outlet to a chip bucket disposed below the discharge outlet, wherein:
• a tubular body open at top and bottom thereof is engaged with a discharge portion of the housing where the discharge outlet is formed, so that an internal space of the tubular body communicates with the discharge outlet;
• the tubular body is provided such that a height position of its lower end opening is displaceable;
• the discharge portion of the housing is formed in a tubular shape having a rectangular horizontal cross-section and is provided to hang downward:
• the tubular body has a rectangular horizontal cross-section corresponding to the discharge portion, covers an outer peripheral surface of the discharge portion, and is provided to be movable in an up-down direction with respect to the discharge portion;
• and
• a front-side outer peripheral surface of the discharge portion that is provided at a front side in a front-rear direction of the chip conveyor in the outer peripheral surface of the discharge portion and a front-side inner peripheral surface of the tubular body that is provided corresponding to the front-side outer peripheral surface of the discharge portion at the front side in the front-rear direction in an inner peripheral surface of the tubular body are spaced apart from each other to form a space between them, and at least a part of a positioning mechanism configured to position a height position of the tubular body relative to the discharge portion is provided within the space.
