Description
- The present application is a continuation of International Application No. PCT/EP11/59731 filed Jun. 10, 2011, which is fully incorporated herein.
- This disclosure generally relates to the field of industrial machines. More specifically, the present invention relates to surface treatment machines equipped for road conditioning operations, as well as methods of manufacturing and operating the same.
- Industrial machines may include mounted cutting rotors that contact a surface over which the industrial machine is operating. These industrial machines may include milling machines or cold planers designed to prepare or treat a surface such as a road surface, pavement, soil, or earth. The cutting rotor, which may have a coarse surface or attachments protruding from its surface, is rotationally driven by a motor. The motor may form part of a drive train that includes a series of pulleys connected by a drive belt that is used to rotate the cutting rotor so that it may contact the surface with a force sufficient to alter, treat, or even remove the surface to a predetermined depth. For operations such as milling a paved surface significant force may be required where the cutting rotor contacts the road surface for the breakup and removal of the surface.
- After treatment by the machine, the surface may no longer be smooth as grooves may be formed due to the cutting rotor cutting into the surface. Present machines may use cutting rotors with finer tool spacing, so that the grooves that are formed on the ground are closer and better resemble a smooth surface, even after treatment.
- However, the procedure to change from a normal cutting operation to a fine milling operation and vice-versa may be time-consuming and accordingly expensive as the procedure may involve changing the cutter rotor.
- The present disclosure is directed, at least in part, to improving or overcoming one or more aspects of the prior art engine component support structures.
- In a first aspect, the present disclosure describes a surface treatment machine comprising a chassis; a cutter member mounted to the chassis for milling a surface; and a smoother member mounted to the chassis for levelling raised edges of a milled surface, the smoother member being positioned behind the cutter member relative to the direction of travel, wherein the smoother member comprises a movably supported impact element for impacting the raised edges of the milled surface.
- In a second aspect, the present disclosure describes a method of manufacturing a surface treatment machine comprising the steps of installing a cutting member to a chassis for milling a surface; and installing a smoother member to the chassis for levelling raised edges of a milled surface, wherein the smoother member is positioned behind the cutting member relative to the direction of travel and comprises a movably supported impact element for impacting the raised edges of the milled surface.
