Embodiment Construction

[0028] figure 1 A milling roller with a cylindrical milling tube 10 is shown, on the roll surface 10.1 of which a plurality of basic parts 11 of the tool holder changing system are welded. These basic parts 11 have exchangeable tool holders 12 . Knives 13 , ie round-shank knives, are always accommodated in the tool holder 12 in a replaceable manner. The basic parts 11 are assigned to one another in such a way that they form a thread, ie a transport thread. In this case, the thread turns from the side of the milled tube 10 onto the roll surface 10.1 in the direction of the middle of the milled tube formed between the two sides. exist figure 1 with 2 Only a part of the tool holder change system is shown in for better visibility. Instead, dashed lines are shown starting from the tool holder changing system, which is not shown, and which represent the central longitudinal axis of the tool 13 . As is clear from these lines, the middle of the milled tube has a number of shippi...

Abstract

The invention relates to an ejector, in particular an ejector for road milling machines, which enables a considerable reduction in maintenance costs.

Description

technical field [0001] The invention relates to an ejector, in particular an ejector for milling rollers of road milling machines or surface mining machines or the like. Background technique [0002] Road milling machines generally have a milling tube on the surface of which a number of tool holders are fixed. In this case, these tool holders are the bulk of the tool holder changing system, which also has a basic piece. This basic part is welded on the surface of the milling tube and accommodates the tool holder exchangeably. The tool holder is used to hold knives, usually round shank knives, as disclosed for example in P3701905A1. These tool holders are arranged on the surface of the milling tube in such a way that a helical thread is formed. In this case, the thread exits the edge region of the milled tube and turns into the center of the milled tube. [0003] The threads coming out of the opposing edge regions therefore each meet in the middle of the milled tube. One...
