具有凿刀保持件和两个凿刀的工具组合
摘要：
本发明涉及由凿刀保持件和至少一个先行的凿刀和跟随的凿刀组成的工具组合，凿刀保持件可固定在地面加工机的铣削滚轮上，先行的凿刀和跟随的凿刀保持在凿刀保持件上，其中，跟随的凿刀关于工具组合在应用于地面加工机时的作功运动布置在先行的凿刀之后，且其中，每个凿刀具有包括刀刃的凿刀尖。对此设置成，跟随的凿刀的跟随的凿刀尖至少局部地具有比先行的凿刀的先行的凿刀尖更大的硬度。由此能够减小地面加工机的由于维修引起的停机时间且至少能够降低凿刀的损耗。
摘要（英）：

The invention relates to a tool combination consisting of a chisel holder, which can be fastened to a milling drum of a soil tillage machine, and at least one leading and one trailing chisel, which are retained on the chisel holder, wherein the trailing chisel is arranged after the leading chisel, based on a working movement of the tool combination in use in the soil tillage machine, and wherein each chisel has a chisel tip having a cutter. According to the invention the trailing chisel tip of the trailing chisel has, at least in some areas, a greater hardness than the leading chisel tip of the leading chisel. Thus stoppage times of the soil tillage machine for maintenance can be reduced and the loss of chisels can at least be decreased.
