Problems solved by technology

Known road milling machines do allow the direction of travel to be precisely controlled, but it is a disadvantage that the rope has to be pulled along the ideal strip to be milled

Embodiment Construction

[0032] Figure 1 is a schematic side view of a machine for processing deposits from surface mining, hereinafter referred to as a surface mining machine. The structure and operation of a surface mining machine is well known to those skilled in the art, so the following will describe those elements of a surface mining machine which are relevant for understanding the purposes of the present invention. Road milling machines, the structure and operation of which are also well known to those skilled in the art, will not be described, since only the milling configuration and the steering configuration are relevant to the invention, as far as the elements involved are relevant to the invention fundamentally these Milling and steering configurations are no different from surface mining machines.

[0033]A surface mining machine for milling and cutting mineral material has an underframe 1 formed of a highly deflective welded structure. Milling configuration 2, located under the chassis,...

Abstract

The invention relates to a road-milling machine or machine for working deposits, such as deposits of coal, ores, minerals, etc. by surface mining. The machine according to the invention has an arrangement 14 for detecting the path followed by a milled edge 13 of a milled strip, with the arrangement for detecting the path followed by the milled edge having means 14 for measuring the distance between at least one reference point I on the machine and the milled edge. The means 14 for detecting the path followed by the milled edge co-operate with the arrangement 6 for steering the track-laying units 3A, 3B in such a way that the machine follows the path followed by the milled edge. The distance between the at least one reference point on the machine and the milled edge can be set in such a way that milled strips situated alongside one another are exactly aligned relative to one another.

Description

technical field [0001] The present invention relates to a road milling machine or a machine for handling deposits, such as deposits of coal, ore, or minerals from surface mining operations. Background technique [0002] There are various known self-propelled machines for milling. In particular, these machines include road milling machines that can be used to remove existing layers of road surface structure, and machines that process deposits from surface mining. [0003] Road milling machines are available in milling configurations with mechanically or hydraulically driven milling drums. Machines that process the stock of surface mining, known as surface mining machines, also have a milling arrangement comprising a milling drum, also known in surface mining machines as cutting drums. The milling drums of road milling machines and surface mining machines have tool holders for milling tools. [0004] The milling drums of road milling machines and heap handlers have a preset...
