Abstract

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.

First claim

What is claimed is:

1. A road milling machine for milling a ground surface, comprising:
a machine frame;
a milling drum housing supported from the machine frame such that an opening exists between the milling drum housing and the ground surface;
a milling drum positioned in the milling drum housing and rotatable in a predetermined direction of rotation about an axis of rotation; and
a hold-down device arranged in front of the milling drum to close the opening, the hold-down…
