  • the invention further relates to a method for milling soil with such a milling device, according to the preamble of claim 11.
  • Milling devices for milling soil with a milling machine which has two pairs of milling wheels at the lower end of a milling machine frame, have long been known as so-called diaphragm wall milling machines.
  • the milling machine is introduced essentially vertically in order to create slots in the ground.
  • the slots can be filled with settable masses to create supporting or cut-off walls, such as those required to enclose construction pits.
  • Such a milling device is, for example, from EP 3401444 B1 or the EP 1452645 A1 known. With this, slots can also be reliably produced with large slot depths.
  • cutter blades Furthermore, it is known to mill off soil by means of so-called cutter blades. Such cutting swords have a cutting chain, which is guided along an elongate guide body. Furthermore, large from the open pit Milling devices are known, which usually have one or two milling wheels with a diameter of 5 meters and larger, for example to mine coal in opencast mines. The milling wheels with horizontally directed axes of rotation are swiveled sideways for milling.
  • the invention is based on the object of specifying a milling device and a method for milling soil, with which an upper layer of soil can be removed in an efficient manner.
  • the object is achieved by a milling device having the features of claim 1 and by a method having the features of claim 11 .
  • Preferred embodiments are given in the dependent claims.
  • the milling device according to the invention is characterized in that in a central region of the mobile carrier device the milling frame is mounted in a linearly displaceable manner on a milling cutter receptacle which can be pivoted about a horizontal pivot axis by means of a pivoting device.
  • a basic idea of the invention can be seen in mounting a milling machine with two pairs of milling wheels on a mobile carrier device so that it can be pivoted about a horizontal pivot axis, so that the milling wheels are not directed vertically downwards, but inclined to the horizontal or horizontally.
  • By moving the mobile carrier device with rotating driven cutting wheels an upper layer of soil can be reliably removed.
  • the tiller it is also mounted in a linearly displaceable manner on the tiller mount, which is also pivotally mounted about a horizontal pivot axis.
  • the milling cutter holder can be a simple lateral bearing with a fixing device or a clamp-like holder.
  • the axes of rotation of the cutting wheels are preferably directed in the longitudinal direction of the carrier device.
  • the carrier device has a first traversing unit and a second traversing unit, which are spaced apart from one another in a transverse direction, and that the milling cutter is mounted between the two traversing units.
  • the milling machine can thus be stored on the carrier device in a central area between the two traversing units.
  • the cutter can be within the circumferential dimensions in the longitudinal direction and be arranged in the transverse direction of the carrier device, so that a particularly good stability of the milling device can be achieved when the carrier device is moved.
  • the displacement units can be adjusted relative to one another, in particular in a vertical direction.
  • the surface can be machined linearly with the milling device.
  • the milling device can be moved along a milled edge, with a first traversing unit still being located on the unprocessed and thus a higher surface, while the second traversing unit is already arranged on the milled and thus lower surface. Due to the individual height adjustability, tilting of the tiller can be avoided and a particularly even removal of a layer of soil can be achieved.
  • the traversing units can be height-adjustable relative to one another, in particular via actuating cylinders.
  • the traversing units can be implemented in any suitable manner, for example with wheels or walking mechanisms.
  • the pivoting device is mounted on the carrier device so that it can be adjusted in a vertical direction.

  • At least one or more linear drives can preferably be provided for adjustment.
  • At least one vertical linear guide is arranged on each traversing unit, on which the pivoting device is mounted.
  • the pivoting device can serve as a yoke or a connecting element between the two traversing units.
  • the carrier device can have an overall structure which forms a supporting frame for the carrier device.
  • the at least one linear guide can also be used via the pivoting device be pivoted.
  • only one traversing unit can be mounted so that it can be adjusted vertically up and down with sufficient adjustment options, provided that the milling frame is also mounted on the pivoting device so that it can be adjusted in a linear manner.
  • a further preferred embodiment of the milling device consists in that the milling machine receptacle is designed in the manner of a clamp and at least one drive unit is arranged for the linear displacement of the milling machine.
  • the milling machine can have a conventional angular milling machine frame and/or an angular or round milling machine guide.
  • the milling cutter holder can be designed in the manner of a clamp with a corresponding rectangular or round holder cross-section.
  • the milling machine can be reliably linearly displaced along the milling machine frame by means of a linear drive, which can have at least one actuating cylinder, a cable drive or a toothed rack with a drive pinion. In this way, a desired milling position of the milling machine in relation to the ground can be set in cooperation with the pivoting device, which in particular can pivot the milling machine frame.
  • a suction pump is arranged on the milling machine frame, which is connected to the suction opening. This means that ground material that has been milled off can be sucked off and removed directly at the milling wheels.
  • the cutting wheels mutually rotate inwards in the direction of the at least one suction opening.
  • At least the area to be milled is under water, so that the suction opening is always below the water level and the milled soil material can be reliably sucked off together with the surrounding liquid.
  • a discharge hose can be provided for discharging the soil material that has been sucked off, for example to a receptacle at the rear.
  • This receptacle for the soil material can be above or below the water.
  • the receptacle can have one or more containers.
  • a collecting element for milled soil material is arranged in the area of the milling wheels. This prevents milled soil material, especially stones, uncontrolled from the be thrown away at the milling site.
  • suction of the removed soil material can be promoted by a collecting element, in particular if it is arranged in the manner of a hood over the milling site. This also counteracts contamination of the environment.
  • precise milling off of a soil layer can be further improved in that the milling wheels are mounted together on a pivoting unit which is pivotably mounted on the milling frame. In this way, an adjustment angle of the cutting wheels relative to the floor area to be processed can be set and adjusted independently of the position of the cutting frame.
  • the pivoting unit can be adjusted by means of an adjusting device, in particular at least one adjusting cylinder, about a pivot axis that is horizontal during operation in relation to the other milling machine frame.
  • the milling device can be used on land. According to one embodiment of the invention, it is particularly advantageous that it is designed for use under water and that at least one connecting line is provided for power supply and/or for data.
  • the corresponding units are provided with the necessary seals so that the milling device can be used on a body of water, in particular also on the seabed, with a depth of a few hundred meters or a few thousand meters, for example to mine mineral resources.
  • the milling device can be provided with an autonomous power supply, in particular a battery.
  • a supply line a so-called umbilical, which is connected to a rear unit, is preferably provided for the supply of energy and/or data.
  • the rear unit can itself be under water or preferably be a supply ship on the water surface.
  • the invention also includes a method for milling soil with the milling device according to the invention, wherein the milling device is pivoted into an inclined position relative to the horizontal and for milling an upper layer of soil, the inclined milling machine is moved with the carrier device along the ground.
  • the actual feed movement is carried out by moving the carrier horizontally along the ground. This enables efficient removal of an exposed layer of soil.
  • the milled soil material is sucked off via a suction pump on the milling machine frame.
  • the extracted soil material can be conveyed to a rear pick-up and transported away from there.
  • a further advantageous variant of the method results, according to a development of the invention, in that the cutting wheels are pivoted in relation to the inclined cutting frame.
  • the pivoting can take place about a horizontal pivot axis. This allows for further fine tuning or adjustment of the cutter wheels.
  • a particularly advantageous variant of use results from the fact that the milling is carried out under water on a body of water.
  • mineral resources in particular can be efficiently extracted from a body of water, in particular from a seabed.
