Dredging vessel

The invention relates to an excavator vessel which is used to carry out different work processes one consisting of two side walls and a vessel bottom and on the excavator boom a horizontal axis pivotable main vessel part and a likewise about a horizontal axis through the main vessel part has through separately pivotable transverse vessel wall, so that the main vessel part and transverse wall can be pivoted relative to one another.

In the case of mobile excavators (so-called shovel or truck loaders) In the normal case, so-called shovels are used as dredging containers with the blade opening forward be moved and loaded in the process. The lower edge of the bucket is

designed as a cutting edge. The loading movement is with such Shovels generated essentially by the moving vehicle. Such a shovel is emptied by tilting it around one horizontal axis, with its contents falling out of the shovel in free fall. Such a drain is often unsatisfactory, especially with sticky goods. The remedial measures used by the operator to improve emptying are time-consuming and even harmful to the excavator and the excavator vessel. You can also use a such a shovel in addition to the actual shoveling very little other work processes are carried out.

To ensure safe emptying of the dredging vessel, is in the case of the known vessels mentioned at the beginning, from which the invention is based, a division of the same into a pivotable one Vessel main part (side walls and bottom) and separately pivotable transverse vessel wall has been provided. This serves for its pivoting movement through the interior of the main part of the vessel as a forced emptying shield for the shovel. In known dredging vessels of this type (British patent specification 937 5 ^ 3) but the pivoting transverse wall is used exclusively for this purpose mentioned purpose.

In order to further increase with the help of a To obtain dredging vessel with a pivotable transverse wall work processes that can be carried out, is in a further known one Pahr excavator design (British patent specification 1 06l 633) provided, the pivotability of the transverse wall of the vessel to create the main vessel part by dividing the vessel into approximately two equal-sized vessel parts that can be pivoted relative to one another. The increase in the number of operations that can be carried out with the excavator is, however, not a serious disadvantage bought that no forced emptying of the vessel halves is possible, and that the excavator vessel exclusively by the driving process of the entire excavator can be filled.

The invention is based on the object of creating a dredging vessel of the type mentioned at the outset which, without reducing, yes, even with an increase in the number of work processes that can be carried out in both directions when the machine is stationary Excavator can be used as a shovel and also allows their forced discharge.

To solve this problem, according to the invention proposed that the end positions of the pivoting range of the vessel, transverse wall DES * are the same at least at the opposing end position of the vessel main portion outside of the both side end edges.

With a dredging vessel designed according to the invention, the dredging vessel can be used both as a gripper and as a shovel, using the transverse wall of the vessel, which can be swiveled over a wide range. But also numerous ^e

other working possibilities can be carried out with the dredging vessel according to the invention, as will emerge from the further below The following description of exemplary embodiments results.

To make the transverse wall of the vessel for the various work options, in particular for its use as a gripper jaw of a gripper, To make particularly suitable, it can be provided according to a development of the invention that the vessel transverse wall on its free end expires in two cutting edges each directed towards one of the two sides. Such double-sided cutting arise at the correspondingly thickened free end of the transverse edge of the vessel, if for their design in the case of a main vessel part with a vessel bottom curved in the shape of a circular arc and with a Vessel transverse wall, which has a common pivot axis in the center of the circle, is provided that the vessel transverse wall is convexly curved at its free end edge after a concentric circular arc, which together with the concave at this end Arched transverse vessel wall end faces forming the cutting edges.

Since the main vessel part with the intended further pivotability the transverse wall of the vessel on both front edges can work together with this transverse wall as a gripper, this option can be used designed in such a way that the two front edges of the vessel bottom are given different shapes and thereby different v / operating gripper is available on one and the same vessel. This can be achieved if e.g. provided becomes that the main vessel part in a manner known per se forms a continuous cutting edge on one of its free bottom edges and is studded with fangs on the other.

If, according to a development of the invention, on a Dredging vessel with a vessel main part with an arc of a circle curved vessel bottom and with a vessel transverse wall, which has a common pivot axis in the center of the circle has drive means for the pivoting movement of the main vessel part and the transverse wall of the vessel about their common pivot axis provides j the pivoting of each by the same, to both sides .from one through the pivot axis and the Center of the main vessel part from certain plane of symmetry allow the measured angular amount, the different types of work of the excavator vessel can be done on both sides of the vessel carried out in the same way. As a result, turning maneuvers of the vehicle can often be saved. Furthermore, this enables the work to be carried out both when the vehicle is pushing and when the vehicle is pulling. This is again important for working in the mountains. There, the propulsive force of the vehicle is added when reversing downhill with the natural downhill drift, so that the digging or filling power can be considerably increased compared to the otherwise usual uphill operation.

On the double boom 11, the parts of a dredging vessel 13 are pivotably articulated on a pivot axis 12 connecting its two ends. The main vessel part, consisting of two side walls 14 and a bottom 15 curved as a cylinder jacket, can be pivoted on the aforementioned common pivot axis 12, just like a transverse vessel wall 16. The transverse vessel wall 16 can, however , be pivoted about the pivot axis 12 independently of the main vessel part Ik ₃ 15, this transverse vessel wall 16 being sealed as tightly as possible on the side walls 14 through the interior of the main vessel part 14, 15 and on both sides over the front edges of the main vessel part 14, 15 can also be pivoted. This follows from the explanation of the further exemplary embodiments. The end positions of the transverse vessel wall 16 pivoted through the main vessel part 14, 15 pivoted in this example are therefore each at a distance cc from the end edges of the main vessel part on both sides.

The cross section of the vessel transverse wall 16 is designed so that its free end is thickened like a mushroom. The end edge 16a of this, which is curved according to the radius of the vessel bottom 15 The transverse vessel wall 16 forms cutting edges l6c with the transverse vessel wall end faces curved concavely at lob.

The main vessel part Ik ₃ 15 has fangs 21 on the free edges of the base 15. However, it can also form cutting edges on these free bottom edges (cf., for example, FIGS. 6 and 7). In order to have both one and the other type of bottom edge available on one and the same dredging vessel, provision can also be made for the vessel main part 14, 15 to form a cutting edge 22 on one of its free bottom edges and to have fangs 21 on the other is.

In the following description of examples for different ways of working with the one explained in FIG. 1 Excavator vessel 13 is provided with a row of ripping teeth 21 on each of the two front edges of the bottom 15.
