The invention relates to a stabilizer or recycler which has a rotor housing, in which a milling/mixing rotoris arranged, and a unitfor discharging binder for soil or base material stabilization. In the civil engineering machine according to the invention, at least part of the supply containerfor the binder, and in particular the part thereof which is of larger volume, is arranged to the rear of the milling/mixing rotorin the direction of working. The center of gravity A of the supply containeris preferably arranged to the rear of the axis of rotationof the milling/mixing rotorin the direction of working. This special way in which the supply container is arranged gives an optimum weight distribution. Whereas the supply container, which is relatively heavy when filled with binder, is situated mainly to the rear of the milling/mixing rotor, the drive unitof the civil engineering machine can be arranged ahead of the milling/mixing rotor. With the supply container and drive unit arranged in this way between the front and rear wheels, the center of gravity of the civil engineering machine is situated in the region of the milling/mixing rotor, which is something that is aimed for in practice.

Stabilizer or recycler

The construction machine according to the invention is distinguished by the fact that an air-processing apparatus () is arranged outside the cab () on the machine frame (), wherein a device () for feeding processed and/or fresh air into the cab and used air from the cab is provided, said device having a feed air duct for processed air for the cab and a discharge air duct for used air from the cab.

Construction machine, in particular road milling machine, miner, recycler or stabilizer

A civil engineering machine for spreading material for spreading on soils or base materials, and in particular a civil engineering machine for spreading binders for soil or base material stabilization, has a container for material for spreading to receive the material for spreading and a spreading arrangement having one or more outlet openings for the discharge of the material for spreading. An anti-dust arrangement is arranged below the outlet openings, and is characterized in that there is created below the outlet openings a spreading compartment which is bounded by one or more first anti-dust members and in that there is created an anti-dust space which is bounded by one or more second anti-dust members.

The construction machine according to the invention is distinguished by the fact that an air-processing apparatus () is arranged outside the cab () on the machine frame (), wherein a device () for feeding processed and/or fresh air into the cab and used air from the cab is provided, said device having a feed air duct for processed air for the cab and a discharge air duct for used air from the cab. The feed air duct of the air-processing apparatus () is connected to the outlet (C) of the air-processing apparatus () and the discharge air duct is connected to the inlet (B) of the air-processing apparatus. In a construction machine whose control station is rotatably arranged on the machine frame, the arrangement with the air-processing apparatus outside the cab has the decisive advantage that it is not necessary to run hoses and/or lines between the rotatable cab and the machine frame. A preferred embodiment of the construction machine provides for the feed and discharge air duct of the air-processing apparatus () to have an outer section () which is formed by a component connected to the machine frame in a rotationally fixed manner and an inner section () which is formed by a component connected to the cab in a rotationally fixed manner, wherein the outer section encloses the inner section. Thus concentric air conduction via the swivel joint of the control station is possible.
