Problems solved by technology

The reason for this is that the known shields cannot directly rest on the road surface, and when the road surface is uneven, for example, if there are fluctuations in the road surface or at the intersection of the milling tracks, this will hinder the advancement, or even not advance, because the shield board is stuck on the road surface

Embodiment Construction

[0036]FIG. 1 shows a schematic view of an embodiment of a rear loading road milling machine 2 of the present invention. The road milling machine 2 has a frame 4, which in this embodiment is supported on three wheels 6, 6, 8, of which two rear wheels 6, 6 (only one of which can be seen in FIG. One wheel) is arranged on the side of the rear area, while the front wheel 8 is arranged in the middle of the road milling machine 2 front area. The rear wheels 6, 6 are adjusted in height by means of hydraulic pressure, and the turning of the milling machine 2 is realized by the front wheels 8, which can rotate around the vertical axis A. Furthermore, such a road milling machine 2 can be carried by a sprocket drive in the position of the wheels 6 , 6 , 8 . In addition, the number of wheels or sprocket drive described above can be varied.

[0037] Inside the frame 4 there is at least one drive for the milling rollers, the wheels 6, 6, 8 and the hydraulic system, as well as additional de...

Abstract

The disclosure describes a rear-loader road milling machine with a milling roll, which is arranged in a roller housing open on the bottom, whereby an opening between a front part of the roller housing and a road surface, facing in a direction of travel a, can be closed with a sealing device, the height of which can be altered. The sealing device can be pivoted around an axis in the direction of travel in front of the milling roll for the purpose of adjusting the height of the sealing device. As a result of the pivotability of the sealing device on an axis, which is arranged in the direction of travel in front of the milling roll, it becomes possible to pull the sealing device slidingly above the road surface so that it follows the unevennesses, for example, the waviness of the road surface or existing milling tracks, following these unevennesses by pivoting frontward and backwards. Interruption or even blocking of the advance by jamming is excluded in this way. The sealing device also provides safe protection against milled material thrown forward.

Description

technical field [0001] The invention relates to a rear-mounted road milling machine with a milling roller arranged in a downwardly open milling roller housing, the opening in the direction of travel between the front part of the milling roller housing and the road surface having a height adjustable The adjustable closing device is closed. Background technique [0002] In the field of road construction, especially the repair and maintenance of road surfaces, road surface milling machines are mainly used today to process road surfaces. [0003] Its known road milling machine mainly includes the structure described below. The road milling machine comprises a frame which is supported on a wheel or chain drive. In addition, a milling roller is arranged on the machine frame, which is arranged in a milling roller housing whose milling roller housing is open downwards, ie towards the road. For conveying the milled material, hereinafter referred to as milling material, known road ...
