DEVICE FOR SPREADING GRANULAR AND/OR POWDERY MATERIAL

摘要

A spreader has a hopper (2) the lower region of which comprises a part-spherical wall portion (12) in which outlet ports (50, 51) are provided for enabling material to pass from the hopper to a distribution member (5). The free aperture of each port is adjustable by a dosing slide (80,81). The dosing slides (80, 81) are controllable by an adjusting mechanism (114) which is able to displace either one of the dosing slides (80, 81) without displacing the other.
