Description

The invention relates to a laying device, a laying vehicle and a method for laying at least one line in a floor.

Laying devices for laying lines in a floor are known from the prior art. For example, laying devices of this type are used to lay underground cables without having to dig a complete trench. For this purpose, the laying devices usually have a plow which tears open the ground along the pulling direction of the laying device, so that a cable can be inserted into the torn open ground.

Depending on the depth at which the cable is to be laid in the ground, high forces can occur which affect the service life and strength of the components can influence. Traditionally, the plow is inserted vertically into the ground. For example, it is also known to provide a vertically aligned trench for a hillside location in order to lay a cable. This is a traditional construction principle.

It is an object of the present invention to at least partially remedy the above disadvantages known from the prior art. In particular, it is an object of the present invention to improve the laying of at least one line in a floor so that the at least one line can be laid at a higher speed and / or with less effort.

The above object is achieved by a laying device with the features of claim 1, a laying vehicle with the features of claim 12, and a method with the features of claim 14. Further features and details of the invention emerge from the respective subclaims, the description and the drawings. Features and details that are described in connection with the laying device according to the invention naturally also apply in connection with the laying vehicle according to the invention and / or the method according to the invention and in each case vice versa, so that with regard to the disclosure of the individual aspects of the invention, reference is always made or alternated. can be.

According to a first aspect of the invention, a laying device for laying at least one line in a floor is provided. The laying device has a coupling interface which can be aligned to a bottom surface of the ground for coupling with a propulsion means which is suitable for moving the laying device along a propulsion direction. Furthermore, the laying device has a plowing means for producing an opening in the ground for laying the line along the advance direction and a positioning unit for positioning the plowing means in the ground. By means of the positioning unit, the plowing means can be brought into a rest position in which the plowing means is located outside the soil, and a plowing position in which the plowing means is located at least in some areas inside the soil. It is also provided that the plow means in the plowing position an angle of inclination by one Has the longitudinal axis running along the propulsion direction. Due to the angle of inclination, the plowing means in the plowing position engages under a floor area of the soil at an angle to the floor surface, preferably whereby the opening is at least partially closed by the action of gravity on the soil area when the plowing means is moved along the propulsion direction.

In particular, the laying device can be a cable plow. The line can in particular be understood to mean an electrical line or a conduit. The soil can preferably comprise soil. For example, it is conceivable that the laying device can lay an empty pipe in a floor, through which different cables can then be pulled. It is also conceivable that the line is a glass fiber line and / or a glass fiber section. The propulsion means can in particular comprise a construction vehicle and / or a tractor. For coupling with the coupling interface, the propulsion means can comprise a counter coupling interface.

The coupling interface can in particular comprise several fastening points with which the laying device can be connected to the laying vehicle. The propulsion direction of the propulsion means can in particular be understood to mean a direction of travel. Furthermore, the bottom surface can be understood to mean, in particular, a bottom surface, preferably in the form of a ground plane, and / or a contact surface of the propulsion means. In the plowing position, the plowing means is in particular oriented at an angle to the ground surface, as a result of which the plowing means engages under the ground area both when moving on a flat surface and when moving on a slope. Due to the oblique alignment of the plow means to the ground surface, in particular an opening can be created which also runs obliquely to the ground surface, ie, for example, that an extension of the opening can be greater than an opening depth. In the inclined orientation in the plowing position, the plow means can preferably have an acute or an obtuse angle to the ground surface. The longitudinal axis about which the plowing means is inclined can be oriented parallel to the direction of advance or be identical to the direction of advance. The plowing means can in particular have further directions of inclination. In particular, the angle of inclination can also relate to a vertical axis and / or a vehicle plane refer, which is preferably oriented perpendicular to the floor surface. The fact that the plowing means is arranged in the plowing position within the soil can include that the plowing means is lowered when transferring from the rest position to the plowing position and thus, in particular when moving the plowing means along the direction of advance, creates the opening and / or plows through the ground. In particular, the plowing means extends below the ground surface in the plowing position.

The plow means preferably comprises a plow blade which can be introduced into the ground in order to enable the ground to be opened. For this purpose, the plowing means can in particular be lowered into the ground by the positioning unit. In the rest position, the laying device can be guided by the propulsion means to a location from which the laying of the line is to begin. The plowing means can be transferred from the rest position to the plowing position by the positioning unit, preferably while the plowing means is moving through the propulsion means, so that a propulsive force of the propulsion means can be used to make the plowing means easier to insert into the ground.

The laying device preferably has a frame which connects the plowing means to the coupling interface. As a result, power can be transmitted from the propulsion means to the plow means in a stable manner via the coupling interface and the frame. The frame can be a rigid or at least partially movable frame. For example, the frame can have joints in order to support the positioning of the plowing means. To transfer the plowing means from the rest position to the plowing position, the positioning unit can be designed, for example, to be hydraulic or an electric motor. For example, the positioning unit can have a hydraulic cylinder through which the plowing means and / or part of the frame can be moved.

The fact that the plowing means reaches under the bottom area of the soil in the plowing position can thus be understood in particular to mean that the plowing means is inserted obliquely into the ground due to the inclined position of the plowing means at the angle of inclination and also plows through the soil at an incline when the plowing means is moved along the direction of advance . The bottom area can thus in particular have a triangular cross section have, which sags when the plowing means is moved further along the direction of advance. In particular, the opening behind the plowing means is closed in relation to the direction of advance. The inclined introduction of the plow means only a small scar is produced in the ground, so that reworking to close the opening is not necessary or is only necessary to a reduced extent. In addition, it was surprisingly found that the inclined position of the plow means the expenditure of force for placing the line at a certain depth can be significantly reduced. The laying device according to the invention thus overcomes a long-standing prejudice of the original construction principle, in which a perpendicular opening is dug into the ground in order to lay a line.

It is also conceivable in a laying device according to the invention that the plowing means has an adjusting means for setting the angle of inclination about the longitudinal axis or that the plowing means is fixedly, i.e. preferably non-adjustable, mounted in the angle of inclination on a frame which connects the plowing means to the coupling interface. In particular, when the plowing means is transferred from the rest position to the plowing position, the frame can also be moved at least in certain areas. For this purpose, the frame can have a lowering joint for lowering the area of the frame. The adjustment means can in particular comprise a joint around the longitudinal axis. The setting means can also have a locking means for fixing the plowing means at the set angle of inclination. The setting option allows an advantageous angle of inclination to be set depending on the type of soil. A fixed installation of the plowing means at the angle of inclination on the frame also has the advantage that the support of the frame can be aligned to the predetermined angle of inclination and thus a lighter frame can be achieved with regard to the strength of the frame. In addition, a complex setting and / or finding of a suitable angle of inclination can thereby be dispensed with.

Furthermore, it is conceivable in a laying device according to the invention that the angle of inclination is greater than or equal to 10 °, preferably greater than or equal to 20 °, to a vertical axis which runs in particular perpendicular to the bottom surface of the floor. It is also conceivable that the angle of inclination is between 30 ° and 45 °. It has been found that such angles of inclination, in particular the angle of inclination of 20 °, an advantageous combination of an achievable depth of the opening and the required force. As a result, the plowing means can advantageously cut through the soil layers when the laying device is moved along the advance direction.

It is also conceivable in a laying device according to the invention that a guide unit is provided for guiding the line into the opening in the ground, in particular wherein the guide unit is arranged on the plowing means. The guide unit can have an at least partially or completely closed guide section through which the line can be guided into the opening in the base. By arranging the guide unit on the plowing means, a particularly direct coupling of the plowing means and the guide unit can be given. The guide unit is preferably arranged downstream of the plowing means in relation to the direction of advance, i.e. in particular when moving the plowing means in the direction of advance. As a result, the line can be laid to a desired depth in the ground, in particular automatically when the laying device is moved. The guide unit can comprise at least one insertion tube for guiding the line into the opening in the base. Advantageously, the laying device and / or the propulsion means can have a holding unit on which at least one line is held, preferably at least two lines are held. For example, the storage unit can have a cable drum or a receptacle for line sections. In particular, the storage unit can be designed to automatically provide the lines. Furthermore, it can be provided that the lines can be fed from the supply unit to the guide unit.

Furthermore, in a laying device according to the invention, it can advantageously be provided that the guide unit has a holding section for at least temporarily supporting the floor area for introducing the line into the ground, in particular wherein the holding section is arranged downstream of the plowing means when the plowing means is moved in the propulsion direction. The holding section can in particular comprise a closed guide section of the guide unit. In particular, in the plowing position of the plowing means, the holding section can extend opposite to the direction of advance. As a result, the opening can advantageously be kept open and supporting the soil area while the plowing means is moved. This makes it easier for the line to be set down in the opening below the soil area before the soil area at least partially closes or sags the opening due to the movement of the plowing means. The holding section is preferably designed to support the floor area along the vertical axis. In this case, the holding section is in particular coupled to the plowing means, so that the holding section is also moved when the plowing means is moved along the direction of advance and exposes the ground area. In particular, the holding section can be of tubular design in order to advantageously guide the line. It can be provided that the holding section is connected to a deflection section of the guide unit, by means of which the line can be deflected from a guide along the plowing means in the propulsion direction during laying.

Furthermore, in the case of a laying device according to the invention, it is conceivable that the guide unit is designed to guide two lines simultaneously into the opening in the floor. In particular, the guide unit can comprise two holding sections for keeping the opening open by supporting the base area in order to support the base area for both lines. The combination with the angle of inclination of the plow means of the laying device can thus achieve an advantageous depth at which the two lines can be positioned. In particular, the guide unit can be designed to guide two lines at the same time, which are laid one above the other at least in some areas. For example, the guide unit can have two guide sections which are arranged one after the other at least in regions in the direction of advance. As a result, it is not necessary for a width of the opening to correspond to the sum of the two line diameters. Instead, the opening can be made narrower, as a result of which the plow means can be made narrower and forces when uncovering can be further reduced.

It is also conceivable in a laying device according to the invention that the coupling interface is designed for releasable or permanent, in particular non-releasable, coupling with the propulsion means. This can ensure that the laying device can be mounted on the propulsion means in a modular manner. For example, a tractor and / or another utility vehicle can thereby be used for further applications. Furthermore, the coupling interface can thereby be stored in a space-saving manner. To the solvable Coupling with the propulsion means, the coupling interface z. B. be designed for screwing with a counter coupling interface of the propulsion means. Furthermore, it is conceivable that the coupling interface is designed to latch with the mating coupling interface of the propulsion means. In particular, the coupling interface can be designed for a form-fitting and / or force-fitting connection with a counter-coupling interface of the propulsion means. For permanent coupling, the coupling interface can be designed, for example, for a material connection, in particular for welding, with a counter-coupling interface of the propulsion means.

Furthermore, it is conceivable in a laying device according to the invention that a, in particular hydraulic, steering unit is provided by which the plowing means can be pivoted about a vertical axis in order to achieve steering when the laying device is moved when the plowing means is in the plowing position. The vertical axis can in particular be understood to mean an axis which, in the plowing position of the plowing means, is oriented perpendicular to the ground and / or perpendicular to the direction of advance. The steering unit can thus enable, in particular, a rudder-like steering of the propulsion means and / or the laying device. In particular, the plowing means can be used as a rudder through the steering unit. Thus, cornering can be made possible by the steering unit with a reduced expenditure of force on the propulsion means. In particular, depending on the ground conditions of the ground, the steering unit can enable steering at all. A curve radius of less than or equal to 50 meters, preferably less than or equal to 30 meters, particularly preferably less than or equal to 20 meters, can thereby be made possible when moving the plowing means.

Furthermore, in a laying device according to the invention, it can advantageously be provided that the plowing means is mounted on an articulated joint so that it can pivot about the vertical axis. In particular, the articulation joint can be part of the frame. The articulated joint can be designed in such a way that a center of gravity of the laying device and / or of a laying vehicle with the laying device shifts from the longitudinal axis to the center of the curve as the steering angle increases. In particular, an axis that is horizontal with respect to the ground through the plowing means and an axis that is horizontal with respect to the ground through the propulsion means, in particular a chassis axis of the propulsion means, can meet at the pivot point at the center of the curve. The articulation can be designed as a swivel joint. Furthermore, the articulated joint can represent a central area for the connection of the plowing means to the coupling interface. For example, it can be provided that a force of the plow means, in particular only, can be transmitted to the coupling interface via the articulated joint. By virtue of the articulated joint, the plow means can advantageously be pivotable about the vertical axis in an angular range of over 90 °, preferably over 180 °. As a result, a change in direction when moving the plowing means is advantageously possible by pivoting or bending horizontally, while at the same time an advantageous transmission of force between plowing means and propulsion means can be made possible.

It is also conceivable in a laying device according to the invention that the steering unit comprises two hydraulic drive means for pivoting the plowing means about the vertical axis, which are articulated at a distance from the vertical axis to pivot bearing points of the plowing means, in particular wherein the pivoting bearing points are symmetrical to one another with respect to the articulated joint, are in particular arranged symmetrically in a center plane of the articulation joint. The hydraulic drive means can in particular be hydraulic cylinders. The pivot bearing points can comprise connecting rod bearings through which the hydraulic drive means are connected to the plow means. The hydraulic drive means can be arranged on one side of the plow means in order to enable the plow means to be adjusted by lengthening and / or shortening the hydraulic drive means. In the symmetrical arrangement, the pivot bearing points preferably have a common axis of rotation. As a result, an advantageous introduction of force can take place without loading the articulation joint with transverse forces.

In a laying device according to the invention, it can preferably be provided that the plowing means has a plowing depth through which an opening depth of the opening in the ground of greater than or equal to 1 m, preferably greater than or equal to 1.2 m, particularly preferably greater than or equal to 1.4 m, in the Plow position can be predetermined, has. The plowing depth of the plowing means can in particular be defined by a length of the plowing means. It can be provided that the plowing means in the plowing position at least partially protrudes from the ground or the opening in the ground, so that the plowing depth can be greater than the opening depth. The plowing depth is preferably designed in such a way that two lines one above the other at a depth of at least 1 m, preferably at least 1.2 m, particularly preferably at least 1.4m can be laid in the ground. As a result, a high overlap height can be achieved, in particular in the case of agricultural areas, while at the same time a high laying speed of two lines can take place at the same time. For example, for the use of fiber optic cables, in particular for conduits for fiber optic cables, cable diameters of up to 80 mm are common. With an opening depth of 1.4 m, an overlap height of 1.20 m, in particular for agricultural use of the soil, can therefore advantageously be achieved even if two lines are laid on top of each other at the same time.

According to a further aspect of the invention, a laying vehicle is provided for laying at least one line in a floor. The laying vehicle has a propulsion means for generating propulsion along a propulsion direction on the ground and a laying device for laying the line in the ground. The laying device comprises a coupling interface, which is coupled to a counter-coupling interface of the propulsion means for alignment with a floor surface of the ground, so that the laying device can be moved by the propulsion device along the propulsion direction, preferably parallel to the floor surface. Furthermore, the laying device comprises a plowing means for producing an opening in the ground for laying the line along the advance direction and a positioning unit for positioning the plowing means in the ground. The positioning unit can bring the plowing means into a rest position in which the plowing means is located outside the soil and a plowing position in which the plowing means is located at least in some areas inside the soil. Furthermore, it is provided that the plowing means in the plowing position has an angle of inclination about a longitudinal axis along the direction of advance, so that the plowing means engages under a floor area of the ground at an angle to the ground surface, preferably whereby the opening when moving the plowing means along the advance direction is exerted on the ground area by gravity is at least partially closed.

Thus, a laying vehicle according to the invention has the same advantages as have already been described in detail with reference to a laying device according to the invention. The propulsion means can in particular comprise a tractor, a utility vehicle and / or the like. The propulsion means can be hydraulic or electrical and / or be driven by an internal combustion engine. The counter-coupling interface is preferably designed to correspond to the coupling interface of the laying device. In particular, the coupling interface and the counter coupling interface can be coupled to one another in a releasable or non-releasable and / or permanent manner. In this case, the coupling interface and / or the laying device is aligned or can be aligned in particular with the floor surface through the coupling with the counter-coupling interface. For example, the frame can extend parallel to the floor surface, at least in some areas. It is conceivable that the coupling interface and the counter-coupling interface are positively, non-positively and / or cohesively connected to one another. So it is conceivable that the coupling interface and the counter coupling interface are welded.

The laying vehicle can therefore be used to advantageously lay the line in the ground. In this case, a propulsion means with a low level of motorization can be used to lay the line, in particular due to the low expenditure of force.

Furthermore, in a laying vehicle according to the invention, it can advantageously be provided that the propulsion means comprises a caterpillar drive. The caterpillar drive can in particular be understood to mean a crawler or crawler chassis. As a result, the weight of the propulsion means and / or the laying vehicle can advantageously be transferred to the ground over a large area in order to reduce damage to the ground. In combination with the inclination of the plow, which causes only a small scar in the ground, this results in a minimally invasive intervention in the ground when laying the lines.

According to a further aspect of the invention, a method for laying at least one line in a floor by a laying device, in particular a laying device according to the invention, of a laying vehicle, in particular a laying vehicle according to the invention, is provided. The procedure consists of the following steps:

• Transferring a plowing means of the laying device for creating an opening in the soil from a rest position in which the plowing means is located outside the soil to a plowing position in which the plowing means is at least partially inside the soil and in which the plowing means is one Has an angle of inclination about a longitudinal axis along the direction of advance, the plowing means reaching under a floor area of the soil obliquely to a floor surface of the soil due to the angle of inclination,
• Moving the laying device along the advance direction while the plowing means is in the plowing position, preferably so that the opening along the advance direction is at least partially closed by the action of gravity on the soil area,
• Insert the lead into the opening.

A method according to the invention thus brings the same advantages as have already been described in detail with reference to a laying device according to the invention and / or a laying vehicle according to the invention. In particular, the method can be carried out by a laying vehicle according to the invention. The transfer of the plowing means from the rest position to the plowing position can in particular be carried out by a positioning unit of the laying device. The laying device is preferably moved by a propulsion device of the laying vehicle. When the line is introduced into the opening, provision can be made for the line to be fed from a storage unit for storing the line to a guide unit, which is coupled to the plowing means, in order to lay the line in the ground. Furthermore, when the line is inserted into the opening, it can be provided that the line is deflected. When the line is inserted, the soil area is preferably at least temporarily supported while the plowing means is being moved.

The line can thus be laid in a simple manner with little expenditure of force and / or at high speed. When inserting the line into the opening, two lines are preferably introduced into the opening at the same time.

Furthermore, it is conceivable in a method according to the invention that the laying device is steered when moving by pivoting the plowing means about a vertical axis. The steering can in particular take place by a steering unit of the laying device. The plow means can be pivoted about an articulated joint. In particular, the laying vehicle can also be steered by pivoting the plowing means. This allows the plowing means to be used like a row to enable steering. Curve radii of less than or equal to 50 m, preferably less than or equal to 30 m, particularly preferably less than or equal to 20 m, can be traversed.

In the following description of some exemplary embodiments of the invention, identical reference symbols are used for the same technical features in different exemplary embodiments.

Figure 1 shows a laying vehicle 1 according to the invention for laying at least one line 3 in a floor 200. For this purpose, the laying vehicle 1 has a laying device 10 according to the invention, which is coupled by a coupling interface 11 to a mating coupling interface 2.1 of a propulsion means 2 and to a floor surface 203 of the bottom 200 is aligned or alignable. By means of the propulsion means 2, the laying device 10 can be moved along a propulsion direction 210 in order to introduce the line 3 into the ground 200. In the propulsion means 2 it can be, for. B. be a tractor, a construction vehicle or the like. The propulsion means 2 preferably has a caterpillar drive 2.2 in order to distribute the weight of the laying vehicle 1, in particular when the soil 200 is used for agricultural purposes. The coupling interface 11 can be designed for a detachable or permanent connection to the counter coupling interface 2.1. For example, the coupling interface 11 and the counter coupling interface 2.1 can be screwed or welded.

In order to create an opening 202 for introducing the line 3 into the ground 200 along the driving direction 210, the laying device 10 has a plowing means 12. In order to be able to initially transport the plowing means 12 to the place of use, the laying device 10 has a positioning unit 14 for positioning the plowing means 12 in the ground 200, as in FIG Figure 2 shown. By means of the positioning unit 14, the plowing means 12 can be brought into a rest position I in which the plowing means 12 is located outside of the soil 200. In particular, the plowing means 12 is raised relative to the ground 200 in the rest position I. As a result, the laying device 10 can be moved by the propulsion means 2 without the plowing means 12 engaging the soil 200. Furthermore, the plowing means 12 can be brought into a plowing position II by the positioning unit 14, in which the plowing means 12 is located at least in some areas within the soil 200. As a result, when moving the laying vehicle 1 along the propulsion direction 210, the opening 202 can be made in the ground 200.

Figure 3 shows a rear view of the laying vehicle 1 with the laying device 10 in a schematic representation with the plowing means 12 in the plowing position II. The plowing means 12 is inclined by an angle of inclination 211 about a longitudinal axis 220. The longitudinal axis 220 is in the Figures 1 and 2 shown along the advance direction 210, ie in particular parallel to the advance direction 210. For example, the longitudinal axis 220 can correspond to a vehicle longitudinal axis of the laying vehicle 1 or lie parallel to it. Because the plowing means 12 is inclined by the angle of inclination 211 about the longitudinal axis 220, the plowing means 12 engages under a floor area 201 of the floor 200 at an angle to the floor surface 203. This leads to a reduced expenditure of force for moving the laying device 10, in particular when the line 3 is to be laid at great depth. If the plowing means 12 is now moved along the advance direction 210, the opening 202 closes at least partially because the soil area 201 sags due to the effect of gravity. This also results in only slight damage to the soil 200. The plowing means 12 is preferably fixedly mounted on a frame 13 which connects the plowing means 12 to the coupling interface 11. As a result, a simple production of the laying device 10 and an advantageous support and / or power transmission between the plow means 12 and the coupling interface 11 can be made possible.

As in Figure 1 As shown, the laying device 10 also has a guide unit 15 for guiding the line 3 into the opening 202 of the floor 200. The guide unit 15 is arranged downstream of the plowing means 12 when the plowing means 12 is moved in the propulsion direction 210. In particular, the guide unit 15 can be arranged directly on the plowing means 12. In the exemplary embodiment shown, the guide unit 15 is designed for simultaneously guiding two lines 3 into the opening 202 of the base 200. For this purpose, the guide unit 15 has two, in particular at least partially parallel, guide sections 15.1. The guide sections 15.1 are preferably closed around the line 3, which in particular runs through it. Furthermore, the guide unit 15 has for each of the lines 3 a, in particular at least partially or completely curved, holding section 15.2 for at least temporarily supporting the base area 201, whereby the introduction of the line 3 into the base 200 is facilitated. In particular, it can be provided that the line 3 can be deflected by the guide unit 15. The holding sections 15.2 thus in particular prevent the bottom region 201 from sagging when the plowing means 12 moves along the propulsion direction 210 before the line 3 is placed. The laying device 10 and / or the propulsion means 2 can advantageously have a holding unit 18 on which at least one line 3, preferably two lines 3, are held. The storage unit 18 can be designed for the automatic provision of the lines 3. In particular, it can be provided that the lines 3 of the guide unit 15 are fed from the storage unit 18.

Due to the angle of inclination 211 of the plowing means 12 about the longitudinal axis 220, the plowing means 12 can be designed with a plowing depth 12.1 through which an opening depth 202.1 of greater than or equal to 1.4 m can advantageously be achieved. As a result, an overlap height 200.1 of at least 1.20 m can be maintained even when the two lines 3 are laid one on top of the other, in particular when the lines 3 are empty conduits for fiber optic cables.

Figure 5 shows a method 100 according to the invention for laying the line 3 in the ground 200 in a schematic representation of the method steps. In this case, a transfer 101 of the plowing means 12 from the rest position I into the plowing position II is initially provided. The laying device 10 is then moved 102 with the plowing means 12 along the advance direction 210. In this case, the lines 3 are introduced 103, in particular automatically, into the opening 202 of the soil 200.

As in the Figures 3 and 4 As shown, the laying device 10 also has a steering unit 16 with two hydraulic drive means 16.1, in particular in the form of hydraulic cylinders, in order to improve or enable maneuverability of the laying vehicle 1 with the laying device 10. By means of the drive means 16.1, the plowing means 12, in particular with the guide unit 15, can be pivoted about a vertical axis 221 in relation to the coupling interface 11 and / or the propulsion means 2. For this purpose, the frame 13 also has a swivel joint, in particular in the form of an articulated joint 13. 1, about which the plowing means 12 is rotatably mounted about the vertical axis 221. The drive means 16.1 are articulated to the plow means 12 by pivot bearing points 16.2, which are in particular arranged symmetrically to a center plane of the articulated joint 13.1. This results in an advantageous introduction of force to the articulated joint 13.1 when the plow means 12 is pivoted about the vertical axis 221. Thus, by pivoting 102.1 of the plowing means 12 about the vertical axis 221, a rudder-like control of the laying vehicle 1 can take place.

It is conceivable that the laying device 10 has an adjusting means 17. By means of the setting means 17, the angle of inclination 211 of the plowing means 12, as in FIG Figure 6 shown, be adjustable. This allows z. B. an adaptation to certain conditions of the floor 200 can be made.

The above explanation of the embodiments describes the present invention exclusively in the context of examples. Of course, individual features of the embodiments can be freely combined with one another, provided that they are technically sensible, without departing from the scope of the present invention.
