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 invention discloses a road marking machine with a splash-proof mechanism for highway engineering and an implementation method of the road marking machine with the splash-proof mechanism for the highway engineering, the road marking machine comprises a feeding device and a marking device, and a rotating shaft is arranged in the middle of the upper end of a bottom plate of a coating barrel; the bottom end of the rotating shaft is fixedly connected with the output end of a driving motor at the lower end of the top plate of the rack, a leakage disc with stirring blades and comb teeth installed on the side wall is arranged on the outer wall of the rotating shaft, a fixing ring movably sleeves the outer wall of the rotating shaft at the upper end of the leakage disc, and a friction sleeve movably sleeves the outer wall of one side of the fixing ring through a connecting rod. The lower end of the friction sleeve abuts against the upper end surface of the leakage disc. A counterweight ball is arranged at one end, which is far from the fixing ring, of the connecting rod. The driving motor is started to drive the rotating shaft to rotate, the stirring blades and the comb teeth are driven to stir the coating in cooperation with the leakage disc, and during stirring, the friction sleeves are attached to the leakage disc to rub and rotate to generate heat to preserve heat of the coating; and the problem that low-temperature freezing paint obstructs construction is avoided.

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.

The invention discloses an automatic road marking machine, including a device body, wherein the device body includes a bottom plate; a pulley block is arranged at both ends of the bottom of the bottomplate; at one end of the top of the bottom plate, an air machine case body is fixedly installed; an air compressor is arranged inside the air machine casing; the other end of the top of the bottom plate is fixedly provided with a storage cylinder; a material storage box cover is arranged on the top of the material storage cylinder body, a cover handle is fixedly arranged at both ends of the top of the storage cover, in accordance with the prior art, the invention has the following beneficial effects: the device is provided with a water storage tank body, storage cylinder, the second connecting pipe and the pumping pump can convey the cleaning agent inside the water storage tank to the inner part of the material storage cylinder through the second connecting pipe by opening the pumping pump, thereby cleaning the inner part of the material storage cylinder, avoiding the tedious steps of removing the material storage cylinder, saving manpower and time, and improving the working efficiency of the device.

The invention discloses a road marking machine device capable of meeting various marking requirements. A main box body is included. A motor belt wheel cavity is formed in the main box body; a slidinggear cavity is formed in the lower side of the motor belt wheel cavity; a rotating block cavity is formed in the left side of the sliding gear cavity; a large straight gear cavity which penetrates through the rotating block cavity, extends rightwards to the sliding gear cavity and is connected with the sliding gear cavity is formed in the left side of the rotating block cavity; a line width adjusting cavity is formed in the lower side of the sliding gear cavity; a motor bevel gear cavity is formed in the right side of the line width adjusting cavity; and a forward bevel gear cavity is formed in the right side of the motor bevel gear cavity. According to a self-propelled marking machine, manual auxiliary pushing is not needed; and under the condition of rapid marking, straightness of a marking line can be ensured and a width of the marking line can be adjusted, the mechanism is suitable for the marking lines with different line width requirements, a spray head does not need to be manually replaced, marking efficiency is greatly improved, an intermittent paint spraying mechanism is adopted, simple conversion between a solid line and a dotted line is achieved, and dotted line markingcan be performed without manually controlling a spray head switch.

The application relates to a road milling machine (1) having a machine frame (2), driving devices (3) connected to the machine frame, a drive motor (4), a driver's station (10), and a road milling apparatus (5) comprising a road milling drum (7) and a milling drum box (6) surrounding the latter and having height-adjustable side shields (8A, 8I) which are arranged transversely to the rotation axis(R) of the road milling drum. An outer side shield (8A) terminates substantially flush with an outer side of the machine frame, and an inner side shield (8I) is offset towards the longitudinal center(M) of the machine from an opposite outer side. An essential concept of the application consists in that a viewing shaft (9) is present so that the inner side shield and / or a road area in front of theinner side shield in the working direction (A) is at least partially visible from the driver's station.
