APPARATUS FOR SPREADING MATERIAL

摘要

A spreader wagon (1) comprises a container (10) for material to be spread. The container (10) is formed by a semi-circular base (14) and side walls (15 and 16) and a downstream end wall (17). A dispensing rotor (30) rotatable in the downstream end (12) of the container (10) dispenses material through a dispensing outlet (19). A piston plate member (45) extending transversely of and slidable in the container (10) from the upstream end (11) to the downstream end (12) retains the material in the container and urges the material into engagement with the dispensing rotor (30). An isolating plate (55) slidable in tracks (57) is lowerable into a closed position for isolating the dispensing rotor (30) from an upstream portion (56) of the container (10) for retaining the material out of engagement with the dispensing rotor (30) until the dispensing rotor (30) has been run up to speed.
