Civil Engineering Machine For Spreading Material For Spreading On Soils Or Base Materials

Abstract

The invention relates to a civil engineering machine for spreading material for spreading on soils or base materials, and in particular to a civil engineering machine for spreading binders for soil or base material stabilization, which has a container (3) for material for spreading to receive the material for spreading and a spreading arrangement (5) having one or more outlet openings for the discharge of the material for spreading. The invention relates in this case both to a civil engineering machine which is intended solely for discharging the binder and to a civil engineering machine, and in particular a stabilizer or recycler, which has a milling or mixing rotor by which, directly after the discharge, the binder can be mixed into the soil or base material which has been milled up. The anti-dust arrangement (7), which is arranged below the outlet openings, is characterized in that there is created below the outlet openings a spreading compartment (8) which is bounded by one or more first anti-dust members (7A, 7B, 7C, 7D) and in that there is created an anti-dust space (9) which is bounded by one or more second anti-dust members (8A, 8B, 8C, 8D). What is achieved in this way is that dust which occurs when the material for spreading is being discharged is first retained in the spreading compartment which is surrounded by the first anti-dust members, thus enabling the dust to settle on the ground. Quite a high proportion of the dust is trapped by this means at an early stage. The dust which is not retained in the spreading compartment is then captured in the anti-dust space which is surrounded by the second anti-dust members.
