Abstract

Claims (30)

1. A feedstock processing apparatus configured to apply, distribute, and compact feedstock in defined layer heights, the feedstock processing apparatus comprising:

a chassis with a traction drive, a first undercarriage, and a second undercarriage, wherein at least one of the first undercarriage or the second undercarriage is coupled to the traction drive;

a frame structure that connects the first and second undercarriage over a span width of the feedstock processing apparatus and provides a working width for the feedstock processing apparatus between the first and second undercarriages;

a material feeding device coupled to or supported on the frame structure;

a material distributing device that is coupled to the material feeding device, that is displaceable at least in certain sections over the span width, that is mounted on the frame structure, and that is positionable at a plurality of application positions within the span width, wherein the material distributing device is configured to apply the feedstock in layers on soil in different, predefinable height positions between the first and second undercarriages;

a control device configured to activate the material distributing device and to set a layer thickness of the feedstock applied in layers; and

a compacting device that is displaceably mounted on at least one of the frame structure or the material distributing device, the compacting device being connected in terms of material flow to the material feeding device, wherein the compacting device includes at least two compacting units configured as a drum or a roller with a rolling axis, in an articulated mount configured to be positionable or alignable relative to one another so that a movement path of the compacting device represents crab steering,

wherein the control device is configured to regulate a respective movement path of the compacting device and the material distributing device in a manner dependent on one another respectively within the working width.

2. The feedstock processing apparatus of claim 1 wherein at least one of:

the compacting device or a compacting unit of the compacting device is mounted rotatably around a height axis or around an axis of rotation inclined at an angle of less than 45° to the height axis, wherein the control device is configured to set a steering deflection of the compacting unit around the height axis or the axis of rotation; or

the compacting device or a compacting unit of the compacting device is mounted in a height-adjustable manner, wherein the control device is configured to set a height position and/or an inclination of the compacting unit.

3. A feedstock processing apparatus configured to apply, distribute, and compact feedstock in defined layer heights, the feedstock processing apparatus comprising:

a chassis with a traction drive and an undercarriage;

a frame structure that provides a working width for the feedstock processing apparatus;

a material feeding device coupled to or supported on the frame structure;

a material distributing device that is coupled to the material feeding device, that is displaceable at least in certain sections over the working width, that is mounted on the frame structure, and that is positionable at a plurality of application positions within the working width, wherein the material distributing device is configured to apply the feedstock in layers on soil in different, predefinable height positions within the working width;

a control device configured to activate the material distributing device and to set a layer thickness of the feedstock applied in layers; and

a compacting device that is displaceably mounted on at least one of the frame structure or the material distributing device, the compacting device being connected in terms of material flow to the material feeding device, wherein the compacting device includes at least two compacting units configured as a drum or a roller with a rolling axis, in an articulated mount configured to be positionable or alignable relative to one another so that a movement path of the compacting device represents crab steering,

wherein the control device is configured to regulate a respective movement path of the compacting device and the material distributing device in a manner dependent on one another respectively within the working width.

4. The feedstock processing apparatus of claim 3 wherein the undercarriage is a first undercarriage, wherein the chassis includes a second undercarriage, wherein the frame structure is supported on the first and second undercarriages and defines a span width of the feedstock processing apparatus, wherein the frame structure provides between the first and second undercarriages the working width for the material distributing device and the compacting device, wherein the material distributing device and the compacting device are each displaceable on the frame structure within the working width.

5. The feedstock processing apparatus of claim 3 wherein the compacting device includes a compacting unit configured to be inclined about an axis of inclination relative to a horizontal plane.

6. The feedstock processing apparatus of claim 3 wherein at least one of:

the material distributing device and the compacting device are configured to distribute and compact the feedstock in horizontal strips with a predefinable longitudinal extent; or

the feedstock processing apparatus is configured to apply, distribute, and compact the feedstock in horizontal strips that are created in a row one after another in a propulsion direction over the working width, with a respective translational displacement of the material distributing device and the compacting device exclusively in a width direction, with a matrix-like movement path with graduated displacement of the undercarriage in the propulsion direction.

7. The feedstock processing apparatus of claim 3 wherein the frame structure includes a longitudinal member that extends at least approximately in an advancement direction of the traction drive and extends over a length corresponding to a multiple of an individual horizontal strip to be created of construction works to be created or over a length corresponding to a multiple of a longitudinal extent of a crossmember of the frame structure that mounts the material distributing device and the compacting device.

8. The feedstock processing apparatus of claim 3 wherein the feedstock processing apparatus defines at least three material transfer points on a material flow path defined by the feedstock processing apparatus from a delivering material transport unit to an application point defined by a material distributing unit of the material distributing device, the at

least three material transfer points comprising:

a first material transfer point from a first continuously-conveying device to a second continuously-conveying device;

a second material transfer point from the second continuously-conveying device to a third continuously-conveying device; and

a third material transfer point from the third continuously-conveying device to the material distributing device.
