Wood chip conveyor comprising: - an impeller for conveying wood chips, the impeller being arranged on a horizontally aligned drive shaft, - radially aligned blades lying radially outward being arranged on the impeller, - a housing which surrounds the impeller in the form of two parallel side walls (21, 22) and a peripheral wall, and which housing has a feed opening for wood chips in one side wall and an ejection opening directed vertically upwards in the peripheral wall through which opening the wood chips are conveyed out of the housing, - a drive for the drive shaft of the impeller, the impeller having a wheel disc and an annular disc, and the blades being arranged between the wheel disc and the annular disc and the wheel disc being attached to the wheel hub or the drive shaft, or the impeller having two annular discs and the blades being arranged between these two annular discs and being connected to the wheel hub or the drive shaft via struts which are arranged on the blades, which struts have a smaller axial extension than the blades, and - the feed opening being arranged in a side wall to which an annular disc of the impeller is adjacent and the feed opening having a lower height above the base than the drive shaft, - the axis of rotation of the drive shaft of the impeller lying outside the feed opening, - the ejection opening, seen in the direction of rotation of the impeller, being arranged between 90° and 270° behind the feed opening, characterised in that - the radial extension of the blades in the direction of the hub on the annular disc does not exceed the radial extension of the annular disc, - the feed opening has a protrusion directed axially into the interior of the housing, which protrusion extends in the axial direction over the annular disc into the housing and which is spaced apart from the rotating blades in the radial direction, and - the protrusion directed into the interior of the housing is axially spaced apart from the wheel disc or the struts arranged on the wheel blades. - an impeller for conveying wood chips, the impeller being arranged on a horizontally aligned drive shaft, - radially aligned blades lying radially outward being arranged on the impeller, - a housing which surrounds the impeller in the form of two parallel side walls (21, 22) and a peripheral wall, and which housing has a feed opening for wood chips in one side wall and an ejection opening directed vertically upwards in the peripheral wall through which opening the wood chips are conveyed out of the housing, - a drive for the drive shaft of the impeller, the impeller having a wheel disc and an annular disc, and the blades being arranged between the wheel disc and the annular disc and the wheel disc being attached to the wheel hub or the drive shaft, or the impeller having two annular discs and the blades being arranged between these two annular discs and being connected to the wheel hub or the drive shaft via struts which are arranged on the blades, which struts have a smaller axial extension than the blades, and - the feed opening being arranged in a side wall to which an annular disc of the impeller is adjacent and the feed opening having a lower height above the base than the drive shaft, - the axis of rotation of the drive shaft of the impeller lying outside the feed opening, - the ejection opening, seen in the direction of rotation of the impeller, being arranged between 90° and 270° behind the feed opening, - the radial extension of the blades in the direction of the hub on the annular disc does not exceed the radial extension of the annular disc, - the feed opening has a protrusion directed axially into the interior of the housing, which protrusion extends in the axial direction over the annular disc into the housing and which is spaced apart from the rotating blades in the radial direction, and - the protrusion directed into the interior of the housing is axially spaced apart from the wheel disc or the struts arranged on the wheel blades.
