The invention relates to a road milling machine, with a milling drum housing partially surrounding a milling drum, wherein the opening between the milling drum housing and the surface of the material to be milled can be closed off by a hold-down device. The distance between the axis of rotation and the hold-down device increases in the specified direction of rotation of the milling drum at least over a section of the gap between the milling drum and the hold-down device. The particular configuration of the hold-down device leads to an improvement in transport of the milled material to the transport arrangement. The gap width increasing in the direction of rotation of the milling drum improves material flow with a relatively small power requirement and relatively low wear of the milling drum.

The construction machine according to the invention is distinguished by the fact that an air-processing apparatus (28) is arranged outside the cab (9) on the machine frame (2), wherein a device (13, 22) 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 (13, 22) is connected to the outlet (28C) of the air-processing apparatus (28) and the discharge air duct is connected to the inlet (28B) 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 (13, 22) to have an outer section (30) which is formed by a component connected to the machine frame in a rotationally fixed manner and an inner section (31) 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.

The invention relates to a highway marking machine, belonging to the technical field of highway engineering machinery, including a body, wherein a hopper is arranged on the body; a stirring bucket isarranged coaxially with the hopper in the hopper, and is rotatably connected with the hopper; the upper part of the hopper and the stirring bucket are provided with openings; a stirring device is arranged in the stirring bucket, and the stirring device comprises a plurality of sets of stirring members arranged along the height direction of the stirring bucket; each set of stirring members includesa plurality of stirring shafts circumferentially and uniformly distributed on the stirring bucket; a plurality of stirring blades are arranged on the stirring shaft along the length direction of thestirring shaft in the stirring bucket; a plurality of agitating shafts in each set of agitating members are located at the same height; the driving member drives the stirring bucket to rotate in the hopper, and the bottom wall center of the stirring bucket is communicated with a discharge pipe which is arranged through the hopper and extends to the outside of the hopper; and the driving member drives the stirring bucket to rotate in the hopper, so that the stirring blades have the stirring effect on the paint, thereby preventing the paint in the stirring bucket from precipitating or agglomerating.
