  • the field of application for such a cultivation system is, in particular, road construction, special civil engineering, tunneling or hydraulic engineering.
  • the cultivator is e.g. used for breaking up sealed surfaces but also for demolition of concrete and for the mining of certain layers of earth and rock.
  • Excavator crops are also often used for mining soft and medium-hard rocks such as limestone or gypsum. It is particularly important in the case of plaster removal that the fines content in the milled material is kept as low as possible.
  • plaster removal Through the use of dredger mills with lateral cutting heads, which are pivoted on the mining wall, the broken off from the front cutting head material is undesirably further crushed by the subsequent cutting head.

  • the individual mounted mills (1) are interchangeable via connecting brackets (8) side by side, one behind the other or at an angle to each other, arranged at the same or different height.
  • this milling system is expensive and, for example, not very suitable for trench construction.

  • the trencher includes worm shafts mounted vertically to the direction of travel of the cutting chain, which push the removed soil away from the excavated trench.
  • a disadvantage here is the limited usability of this machine. For large-scale material removal on a wall of the Trencher is unsuitable.
  • the trencher is also exposed to high mechanical stresses due to its high-guided construction. The forces occur not only in the longitudinal direction of the rotating milling chain, but also vertically to the chain, especially if the milling tool hits obstacles such as stones or the like.
  • the object of the invention is to further develop an attachment rearing system for attachment to a movable carrier arm of a carrier device in such a way that it can be used for different milling and cutting operations without substantially impairing the efficiency of the individual work situations.
  • the milling bits of the milling chain form a semi-cylindrical mantle surface at the exposed front end of the milling chain. In this case, the front reversing line of the cutting chain is located substantially in a plane tangent to the milling lateral surfaces of the two cutting heads.

  • This interchangeability of the cutting heads makes it possible to remodel and use the mounted rearing system for other applications. For example, cutting heads with a narrower shape can be exchanged for those with a wider shape. Another possibility is to generally omit the cutting heads in order to work exclusively with the milling chain.
