| 摘要 | A spreader for spreading granular and/or powdery material comprises a hopper (2) for receiving material to be spread. Said hopper (2) has a wall portion (107) comprising at least one outlet port (103, 104, 105, 106). The spreader is provided with at least one rotatable distribution member (5, 6) underneath the said outlet port (103, 104, 105, 106). The rotatable distribution member (5, 6) has an upwardly axis of rotation (86) being located outside the area of the said outlet port (103, 104, 105, 106). Said outlet port (103, 104, 105, 106) is surrounded by an edge (126, 127, 130, 134, 135), a part of which, being the inner edge (134, 135), is located lower and nearer to the said axis (86) than the remaining part (126, 127, 130) of the said edge. A dosing slide (142, 143, 144, 145) is displaceable in the area of the outlet port (103, 104, 105, 106) for adjustment of the effective outlet opening. A lower edge (150) of the said dosing slide (142, 143, 144, 145) cooperates with the said inner edge (134, 135) to form the effective outlet opening. Said inner edge (134, 135) is curved so that a middle portion (141) extends towards the central part of the area of the said outlet port (103, 104, 105, 106). The spreader furthermore comprises means for moving the said dosing slide (142, 143, 144, 145) towards and away from the said inner edge (134, 135), in such a way that the smallest effective outlet opening consists of two passages, whereby a part of the said middle portion (141) is overlapped by the said dosing slide (142, 143, 144, 145). | ||||||
