Definitions
- the present invention relates to a material collection container of a suction dredger.
- the material collection container includes a longitudinally extending container wall, a hinged lid, and a seal between the top edge of the material collection container and the lid.
- the invention also relates to a suction dredger with such a material collection container.
- suction excavators which are regularly equipped with a material collection container for receiving the material that has been sucked up.
- Such a suction excavator is known from DE 3837 670 A1, comprising a pneumatic suction nozzle, a collection container for the sucked-up soil or comparable material, into which the suction nozzle opens and in which the sucked-up material is separated from the suction air flow, and a container connected to the collection container Suction fan to generate the suction air flow.
- Other common components of suction dredgers include guide elements for the suction nozzle and filters for cleaning the suction air before it leaves the collection container and is released into the environment.
- a collection container is used, which can alternatively be tilted about one of two tilting axes running in the longitudinal direction of the vehicle to the respective side of the vehicle in order to pour out the material separated in the collection container.
- EP 3436 306 B1 describes a vehicle, in particular a suction excavator, with a vehicle frame, a material collection container that can be tipped out and suspended in a tilting axis running parallel to the longitudinal axis of the vehicle, with a telescoping device and at least one rotary drive, which is arranged on the container-side end of at least one telescopic arm , to allow rotation of the material collection container around the tilting axis.
- DE 102016 105 850 B4 shows a material collection container of a suction dredger, in which case the material collection container can be closed by means of a cover that is divided into at least two parts.
- the material collection container has a flat top edge on which the cover rests in a working position in order to seal the container tightly so that a negative pressure can be generated in it.
- EP 0749 870 A1 relates to a utility vehicle in the form of a tipper that can be emptied to the rear.
- the tipper includes a container formed by a self-supporting wall made of simple steel sheets.
- the wall is U-shaped and formed by segments that are angled to each other.
- CN 202243117 U shows a truck comprising a body and a top cover.
- the car body is open at the top.
- the top cover is placed on top of the car body and closes the opening.
- the car body consists of a floor panel and a car wall which extends upwards around the floor panel.
- the top cover consists of a top panel and side walls that run down around the top panel.
- the upper Cover is attached to the car body so that the side walls are positioned on the outside of the car wall.
- a seal located on the top cover is used to prevent gases from escaping from the car body.
- DE 102017 108731 B4 discloses a suction excavator with a pivotable filter unit, which has a material collection container that can be tilted out and a cover that closes it in a working position. This material collection container also has a flat upper edge.
- General material containers of construction vehicles can be divided into two basic designs. While round containers are often used for the transport of liquids and gases, tipping containers with a square cross-section are usually used in construction vehicles for the transport of earth material and the like. Round containers, such as those of a tanker, are very expensive to produce because they have to be built as uniformly as possible in order to withstand the overpressure that prevails. However, they provide an optimal loading volume and high pressure resistance with a comparatively low weight. Another disadvantage is that the round container is usually emptied through a small opening in the rear, which means longer loading and unloading times. In contrast, loading and unloading a tipping container through a large opening is much quicker and easier.
- the tipping container also has a high manufacturing cost, since due to the many necessary reinforcements on the largely flat container wall, many welds are required for a desired high level of rigidity. This results in a higher net weight, many surfaces for corrosion and fractures or leaks in the weld seams.
- the suction dredger uses negative pressure to pick up material, it is particularly important that the negative pressure generated by a blower unit is communicated with as little loss as possible to a suction nozzle in order to pick up material there.
- the known suction dredgers which have a material collection container that can be closed by a cover, have considerable disadvantages.
- the negative pressure required for the suction process can only be generated with the fan units used if the collection chamber is tightly closed and no secondary air is drawn in.
- the sealing effect between the cover and the collection chamber can be massively impaired by construction tolerances resulting from the manufacture.
- a seal is used in the contact area between the cover and the suction chamber. In this case, however, the problem remains that, especially during the emptying process, parts of the material emptied from the collection chamber often remain on the flat upper edge of the collection chamber or the seal, which then significantly impairs the sealing effect when the lid is closed and/or can damage the seal.
- the suction material left in the sealing area must therefore be removed manually before the lid is closed.
- the object of the present invention is therefore, based on the prior art, to provide an improved material collection container of a suction excavator, which ensures high rigidity, with low material and production costs, and at the same time improved vacuum tightness in order to achieve the required suction vacuum with little provide energy expenditure.
- the material collection container according to the invention is designed for use as part of a suction dredger.
- the material collection container extends in the longitudinal direction of the suction dredger and comprises a container wall extending in this direction.
- the longitudinal direction corresponds to the direction of travel of the suction dredger.
- the container wall is closed at both of its end faces by a front and a rear end wall, so that a trough-shaped container interior is formed.
- a cover of the material collection container is pivotably mounted on a cover axis. The cover closes the material collection container in a closed position on its upper side and opens it in an emptying position in order to be able to empty the material collection container, ie to be able to remove the material that has been sucked up.
- the material collection container has a seal which is arranged between its upper edge and the cover in such a way that the material collection container is sealed off when the cover is in the closed position in order to maintain the negative pressure required for suction operation to be able to build up in the material collection container.
- the material collection container In the closed position, the material collection container is thus sealed in a gas-tight manner, for which purpose the container wall and the end walls must also be tightly connected to one another, at least in the vacuum area required for the operation of the suction dredger.
- the material collection container essentially has a U-shaped or trough-shaped cross section, with the bottom surface, the side surfaces and the front surfaces being designed to be gas-tight and the top of the container being closable in a gas-tight manner by the pivotable cover.
- the container wall has several side segment surfaces that merge into one another at stiffening edges.
- the stiffening edges run in the longitudinal direction of the material collection container, preferably parallel to the longitudinal axis of the vehicle. Particularly preferably, several or all such stiffening edges run parallel to one another. Furthermore, at least some, preferably the majority of the side segment surfaces are arranged at an angle to one another, so that the U-shaped cross section of the material collection container is formed in this way.
- the container wall has an upper edge which is formed by a folded section of the container wall as a hollow profile which is closed at least on the upper side directed towards the lid, preferably closed around the circumference. The result of this is that the upper edge has a smooth surface, in particular one that is not disturbed by weld seams.
- An advantage of this design is that the smooth surface resists wear when the absorbent material is dumped along the edge when emptying the container. Also, it comes despite the strong Turbulence in the suction tank does not lead to unwanted deposits or noise on the weld seams.
- the material collection container can thus be dimensioned for an operating pressure, namely a negative pressure of up to -0.65 bar, without irreversible deformations occurring on the material collection container during operation of the suction dredger.
- a plurality of adjacent side segment surfaces are preferably formed in one piece, i. H. the stiffening edges running between them are not produced by a joining process but by forming.
- Particularly preferably, mutually inclined segment surfaces adjoining one another are at an angle of >90° to ⁇ 180°, preferably of 110° to 170°, at their enclosed stiffening edge.
- a plurality of segment surfaces are formed from a single piece of sheet metal and divided by formed stiffening edges.
- the aim is to produce the pieces to be connected to one another by joining processes (eg welding or folding) in a small number and instead with a large surface area.
- the stiffening edges are then formed as beads or with a similar design, so that the surface Stiffness is increased, but at the same time connections prone to leakage are avoided.
- individual sections of the material collection container can also be additionally provided with stiffening elements, e.g. B. struts are equipped.
- the width of side segment surfaces that are not additionally stiffened is preferably no greater than 150 times, particularly preferably no greater than 100 times, their respective material strength or thickness.
- the dimensioning and the determination of optimized geometrical conditions of a side segment area is preferably carried out using suitable model calculations, for example using the finite element method (FEM). Taking into account the geometric conditions, the distribution of the bearing forces, determination of the line loads and maximum bending moments and the resulting bending stresses, a suitable dimensioning formula can be determined so that the yield point Re of the material can be determined.
- FEM finite element method
- the optimal segment width of the side segment areas and the approximate Position of the stiffening edges are determined in the container wall, so that the largest possible volume for absorbing suction material is achieved with a high inherent rigidity of the material collection container.
- the container wall of the material collection container, formed from the side segment areas determined using the aforementioned dimensioning formula, should be simulated and tested for their load-bearing capacity using the finite element method (FEM).
- FEM finite element method
- At least one additional stiffening element is arranged on the side segment surfaces, which preferably have a width greater than 150 times their material thickness.
- This can, for example, be in the form of a crossbar or a profile, preferably on the outside of the segment surface, so that the rigidity of the segment surface is increased and deformations are prevented.
- the material collection container preferably has one or more floor segment surfaces which are formed on the underside as the floor of the material collection container.
- the floor segment surfaces also preferably merge into one another at stiffening edges.
- additional rigidity can also be generated in this area by additional stiffening elements, which are preferably arranged on the outside of the floor segment surfaces. This can be used above all in the area of the contact areas or other force application points.
- the material collection container has a particularly stiffened side segment surface, which is arranged on that side of the material collection container over which it can be tilted for emptying.
- This stiffened side segment surface has additional stiffening elements, preferably on the outside. This also ensures increased rigidity, so that there is no risk of deformation or damage to the container wall when it is emptied. Due to the design of the stiffened side segment surface, which is nevertheless largely flat and free of obstacles on the inside, the suction material can slide along this surface more easily and without residues in the emptying position of the material collection container.
- the seal which runs to seal between the upper edge and the lid, is embedded in a groove which runs on the underside of the lid facing towards the material collection container and which extends parallel to the upper edge of the material collection container in the closed position of the lid. It should be pointed out that in modified versions the seal can also be attached in another suitable manner, provided gas-tightness between the upper edge and the cover is nevertheless guaranteed.
- the seal preferably has a rectangular cross-section that is selected to match the width of the groove, so that the seal sits tightly in the groove and does not jump out of the groove even when vibrations or movements occur.
- the upper edge to be sealed runs at least along the side walls of a collection chamber of the material collection container, preferably along the side walls of the entire material collection container if it is to be sealed off from the cover as a whole.
- the course of the upper edge is preferably formed by two edge surfaces which converge at an angle, so that the edge surfaces of the upper edge enclose an angle ⁇ and form a joint line which runs in the sealing plane.
- the upper edge points at the line of the converging edge surfaces has a width that is preferably smaller than the width of the groove, so that in the closed position the upper edge dips into the seal or is pressed into it.
- a significant advantage of this preferred configuration of the top edge is that there is no horizontal surface left on it, on which material residues can be deposited when the lid is open. In particular, when the material collection container is emptied, all parts of the material sucked up immediately fall off the top edge so that they are no longer pinched between the seal and the top edge when the lid is closed.
- the design of the upper edge with the two mutually inclined edge surfaces which are preferably in one piece at the abutting edge and merge into one another without unevenness, also leads to a high inherent stability of the upper edge due to the profile-related rigidity and at the same time to protection of the seal, since a sharp , the seal possibly damaging edge is avoided.
- the seal particularly preferably has a closed surface or at least one with low porosity, so that particles of the suction material cannot settle in the pores and thus wear out the seal. This guarantees, on the one hand, easier cleaning and, on the other hand, a long service life of the seal.
- the U-shaped cross-section stiffens the material collection container in such a way that twisting or deformation of the upper edge is reliably avoided even with the required negative pressure in the container. This is an important prerequisite for a permanently tight closure by the lid carrying the seal.
- the top edge which is preferably trapezoidal in cross section, prevents dirt particles or other deposits from adhering there and thus impairing the sealing effect.
- the seal is preferably soft-sealing, so that movements are better absorbed and structural tolerances resulting from the manufacture of the material collection container are better compensated.
- the upper edge of the collection chamber can preferably be pressed about 3-15 mm into the seal due to the soft sealing material of the seal. This results in a better sealing effect, since the seal adapts to the rounded top edge. In this way, large construction tolerances can be compensated for on a larger scale.
- the negative pressure of up to -0.65 bar that is usually generated with suction dredgers can therefore be maintained with less energy consumption. With increasing negative pressure during the work process of the suction dredger, the cover including the seal is sucked in more strongly. Since the seal is positively located within the groove in the cover, the seal can only deviate in the direction of the upper edge and thus seals the material collection container more tightly.
- the upper edge of the material collection container is preferably designed with a triangular or trapezoidal cross section, in particular in the form of a hollow profile.
- the angle ⁇ which is formed by the two edge surfaces of the upper edge, is preferably about 20° to 120°, particularly preferably between 45° and 90°. This angular range leads to a high rigidity of the profile, so that a deformation of the upper edge due to the negative pressure in the collection chamber and due to the pressure of the cover being pressed on is counteracted. Due to this, the life of the seal of the material collection container is extended.
- the edge surfaces of the upper edge that are inclined in this way have the advantage that little or no absorbent material can settle on the edge surfaces.
- the inner inclined edge surface deflects the suction flow in the collection chamber so that the suction material in the suction flow is less likely to wear the inner edge surface and the seal located within the groove.
- the upper edge at the joint line of the edge surfaces preferably has an outer radius in the range of 8-65 mm, particularly preferably 10-25 mm.
- the result of this is that the upper edge has a smooth and, at the same time, sufficiently wide surface for the sealing effect.
- An advantage of this design is that the seal is protected in the closed position, since the force exerted on the upper edge when the lid is placed on arises, acts on a rounded surface.
- the smooth surface counteracts wear in the emptying position when the suction material is tipped out along the edge.
- the invention also relates to a suction dredger with a material collection container according to one of the previously described embodiments.
- the material collection container is preferably attached to the vehicle in such a way that it can be tipped out in the direction of a longitudinal side of the vehicle. In particular, the material collection container can be tipped out on both sides of the vehicle.
- an elevated position of the tilting axis is provided in order to allow the material collection container to be emptied onto surfaces of different heights, for example a vehicle standing next to it.
- the tilting axis preferably runs in a plane of symmetry of the material collection container, which particularly preferably includes a longitudinal axis of the vehicle in a resting, working or transporting state.
- the material collection container preferably has other components.
- the material collection container preferably comprises a suction connection on its rear end wall and a suction flow guide which leads from the suction connection through the collection chamber already mentioned to a filter unit and from there via a fan to an exhaust air outlet.
- the material collection container preferably comprises a pivot bearing on each of its two end walls, which allow the material collection container to be suspended in the tilting axis. Due to its design with stiffening edges, the material collection container has considerable advantages over the previously known container shapes that have hitherto been used in suction excavators. The large opening of the material collection container, which can also be realized and which can be closed by a lid, enables the absorbent material located in it to be removed quickly.
- stiffening edges in the container wall due to the stiffening edges in the container wall, separate stiffeners can be dispensed with or their number can in any case be reduced, so that a low intrinsic weight can be achieved with a high degree of rigidity of the material collecting container. Finally, there is a larger volume available for collecting material than with conventional material collection containers.
- the combination of the container wall with stiffening edges and the top edge shaped as a hollow profile results in a very stiff edge and at the same time provides an optimized contact surface for the seal in the lid.

- directly adjacent side segment surfaces enclose an angle in the range ⁇ 90° to ⁇ 180°.
- the stiffening edges are positioned during the design process using the above-mentioned FEM calculation in such a way that they increase the overall rigidity of the material collection container compared to a container wall without stiffening edges.

- the width of the side segment area is ⁇ 40cm.
- stiffening elements 11 are arranged as transverse struts on the outside of the floor segment surface 10 and in the longitudinal direction, which can be designed as a hollow profile. If necessary, such stiffening elements can also be attached to individual side segment surfaces and/or the end faces, preferably on their outside.
- the end walls 03 also have segment surfaces and stiffening edges.
- the end walls are essentially perpendicular to the side segment surfaces 09 of the container wall 02. This increases the rigidity of the entire material collection container.
- Fig. 4 shows a sectional view of the container wall 02, including an upper edge 08 of the material collection container 01 in an early dimensioning phase.
- the cross section of the container and the position of the stiffening edges can be optimized step by step until the desired compressive strength is reached.
- the side segment surface which is arranged on the tipping side of the material collection container, should form a surface that is as large and straight as possible so that the suction material can slide out of the container more easily and with less resistance in an emptying position.
- the side segment surfaces 09 can be folded from a piece of sheet metal at the stiffening edge 04 or can be made in several parts, so that they are connected to one another at the stiffening edges 04, preferably by welding.

- the cover 06 is preferably designed as a substantially flat plate. Alternatively, the cover 06 can be made in two or more parts or have elevations and/or depressions.
- On the bottom A groove 12 runs in the cover 06, into which a seal 07 with a rectangular cross section is embedded in a form-fitting manner.
- the groove 12 can additionally have a continuous or partial constriction on its open side in order to prevent the seal 07 from falling out.
- the upper edge 08 runs below the groove 12 and, in the closed position, dips into the seal 07.

- the cover 06 closes the material collection container 01 in such a way that the upper edge 08 is pressed into the seal 07 (FIG. 6).
- the one or more side segment surfaces 09 which is/are arranged on the tilting side of the material collection container 01, form/form a surface that is large compared to the opposite side segment surfaces and free of obstacles on the inside, so that the suction material in the emptying position, ie can slide out of the container easily and with little resistance when the material collection container is tilted.
- On the outside of said large side segment surface 09 there are therefore several stiffening elements 11 running transversely to the longitudinal extension of the segment surface, which each support the side segment surface at several points.
- stiffening elements 11 can at the same time form the holder for the tilting axis 18 and for the pivot bearings 22 positioned at the front. Further stiffening elements 11 are arranged on the outside of the floor segment surface 10 and are shaped as transverse and longitudinal struts, with the stiffening elements 11 running in the longitudinal direction preferably being designed as a hollow profile.

- the container wall preferably has a material thickness of 4 mm, the width of the individual side segment surfaces 09 is about 35 cm on the side facing away from the tilting axis 18 between successive stiffening edges.
- the end walls 03 also have side segment surfaces 09 and stiffening edges.
- the end walls 03 are substantially perpendicular to the side segment surfaces 09 of the container wall 02. This increases how already described above, the rigidity of the entire material collection container.
- the material thickness and width of the segments installed on the front sides correspond to those on the side of the container facing away from the tilting axis.
- FIG. 8 it can be seen from FIG. 8 that in addition to the collection chamber 23 further chambers are provided in the material collection container, B. filter units and the fan unit are housed.
