    Cross-section, which device is arranged substantially perpendicular to the direction of movement of the conveyor and the wedge tip is directed in the return direction and the wedge base in said device is directed in the forward direction.
    Furthermore, EP-B-0 532 484 discloses a transport element of a reciprocating scraper for displacing sludge in sedimentation basins and similar objects at water treatment plants, which elements have a cross section which has a downwardly directed surface, a substantially curved, convex surface and a substantially vertical concave surface, which concave surface is directed in the forward, transporting direction.
    All transport of sludge takes place with these elements placed in a perpendicular relation to the longitudinal direction of the conveyor, either a chain, net or a bar moves over the bottom of the sedimentation basin, the chain moving continuously in one direction, and the net and bar working forward and back.
    Previous transport elements have always been welded to longitudinal drawbars, nets and the like on their upper side, which welding requires special training for certification of welding-skilled personnel, and creates tensions between the different materials, which leads to the transport element bending and thus transporting worse. Often, layers are built up under the transport element of sludge that is not transported but compressed and lifts the entire scraper conveyor.
    SUMMARY OF THE PRESENT INVENTION An object of the present invention is to provide an arrangement which meets these problems and creates an easily assembled conveyor with retained shape after assembly. This can be achieved by a construction which in a simple manner allows the joining of several elements to reduce space, as well as a rational mounting device is provided.
    Description of the present invention It has now surprisingly been found possible to meet these requirements and solve these problems by the present invention relating to a conveyor comprising a sludge scraping, and conveying arrangement comprising primarily a scraping and transporting element to be arranged in a simple and rational manner. a sedimentation basin at water purification plants, the conveyor comprising a) a series of slides to be arranged to the bottom of a sedimentation basin, b) a drawbar to be arranged reciprocating, c) at least two outer rods arranged parallel to said drawbar, d ) at least four oblique struts arranged in pairs to and between the outer rods and the drawbar, and e) a series of transport elements arranged to the undersides of the drawbar, outer rods and oblique struts. In a preferred embodiment of the invention, friction-reducing elements arranged for the transport elements are to abut against said slide rails. In a preferred embodiment of the invention, the transport elements consist of hollow bodies which can be fixed to each other.
    In a preferred embodiment of the invention, friction-reducing elements arranged for the hollow bodies are to abut against said slide rails. In a preferred embodiment of the invention, the hollow bodies are fixable to each other by means of a groove and a locking heel joint. In a preferred embodiment of the invention, said drawbar is axially arranged to a first hollow body by means of a bolt and locking lug bolt connection.
    In a preferred embodiment of the invention, said outer rods are fixably arranged to a first hollow body by means of a groove and locking bolt bolt connection.
    In a preferred embodiment of the invention, the transport element consists of a solid, concave arcuate body arranged in its transport direction, arranged to be fixed to said drawbar, outer rods and oblique struts by means of screw connections.
    The design of the conveying element means that after mounting in a sludge basin, it will have a triangular, or wedge-shaped cross-section open in the conveying direction.
    The invention will now be described in more detail in the following with reference to the accompanying drawing, in which FIG. 1 shows a perspective view of a scraper and transport device according to the present invention; FIG. 2 shows a perspective view of the scraper and transport element in the present invention together with mounting device; FIG. 3 shows in a perspective detail of attachment of spacer struts between outer rods and central drawbar to said outer rod in the embodiment according to the present invention; FIG. 4 shows in a perspective detail of attachment of spacer struts between outer rods and central drawbar to said drawbar in the embodiment according to the present invention; FIG. 5 shows the detail of attachment of a drawbar; and FIG. 6 shows an alternative shape of a transport element in the conveyor according to the invention.
    The present invention has in a preferred embodiment a sludge conveyor generally with a number of transporting elements 1, a drawbar 11, two outer rods 12 arranged parallel to the drawbar, four oblique struts 20 arranged between the drawbar 11 and the outer rods 12 and three slides 13, which are later attached to a mud pool bottom.
    The drawbar 11 is connected to a motor (not shown) for a reciprocating motion.
    Normally, the width and length of the conveyor are adapted to the sludge basin to be provided with a conveyor. In the case of very wide basins, you can place two or more conveyors next to each other and let them work in parallel.
    With 1 is indicated in FIG. 1, 2 and 5 generally a conveying element for a sludge basin, which element comprises a lower horizontal hollow body 2, such as an aluminum extruded profile comprising a forwardly inclined conveying surface 3, a lower horizontal bottom 4, a rear also forward-facing back surface 5 and a upper surface 6 provided with a groove 7. The inclined conveying surface 3 is indicated here inclined in relation to an imaginary horizontal plane. Furthermore, the transporting element comprises a top part element 8, such as an aluminum extruded profile, provided with a locking lug 9 adapted to be inserted into the groove 7 for a tight fit between the hollow body 2 and the top part element 8. The top part element 8 connects in shape to the hollow body 2 to form a final transport element 1 with in this embodiment the shape of a "shark fin", as shown in more detail in FIG. 2 and 5.
    The groove 7 has in cross section the shape of an upwardly truncated triangle or the shape of a lower square part with an upper with smaller cross-sectional area square part. The purpose is to achieve a locking or tight fit to one in the groove inserted locking lug 9 with corresponding shape. The transporting element 1 is suitably made of aluminum, as mentioned above, or of a steel grade, such as preferably stainless or acid-resistant steel.
    The conveyor is easily mounted against the slides 13 by placing the transport elements across the basin at equal distances from each other, a distance which is basically determined by the expected amount of sludge to be transported. The distance between the transport elements is defined by vertical holes arranged in the outer rods 12 and the drawbar 11, which are intended to receive reading bolt joints 16 with locking lug 17. When the hollow bodies 2 of the transport elements 1 are placed, the locking lug 17 of the drawbar 16 bolt joint 17 is inserted into the groove 7 2, whereby the drawbar 11 will be placed in the upper part of the transport element 1, after which top part elements 8 with their locking lugs 9 are inserted into the hollow bodies 2. These top part elements 8 then have a length which takes up the distance between the drawbar 11 and the outer rod 12. Then the outer rods 12 are inserted with their bolt joints 15 with its locking lugs 17 in the hollow body 2, the outer rods 12 being placed in the upper part of the transport element 1. Outside the outer rods 12, further top part elements 8 are then inserted.
    In order to maintain the parallelism partly in the longitudinal direction and partly in the transverse direction, the conveyor in the embodiment shown comprises four oblique struts 20 placed in pairs between the outer rods 12 and the drawbar 11. The inclined struts 20 are fixed by means of screw connections to the outer rods 12 via a mounting plate 21. additional mounting plate 22.
    Between the transported elements 1 and the slides 13, a friction-reduced element 23 is arranged. This friction-reducing element 23 is suitably made of a polymeric material.
    The friction-reduced element 23 is locked against the transport element 1 by a snap coupling where a bead 18 in the friction-reduced element 23 is snapped into a corresponding groove 19 in the back surface 5. The friction-reduced element 23 is clamped over the lower horizontal bottom 4 of the hollow body 2 and upwards 3, and its rear forward facing surface 5.
    In an alternative embodiment (FIG. 6) of the transport element, it consists of a solid, concave arcuate body 24 arranged in its transport direction, which is fixed to said drawbar 11, outer rods 12 and oblique struts 20 by means of screw connections 25. 24 through a snap coupling where a one foot 26 of the arcuate body 24 is snapped into a corresponding groove 27 in the friction-reduced element 23.
    By means of the present invention it is achieved that a simple assembly in a sludge basin can be achieved and further that stresses which cause bends in the construction are eliminated. Because the drawbar lies in the upper part of the construction, the transport elements 1 are also supplied with a load which provides an even sludge transport, since the transport elements are to some extent forced down towards the bottom of the basin with an even pressure.
