Definitions

  • the invention relates to a storage container for a bulk material according to the preamble of claim 1.
  • Such a reservoir is such.
  • a predetermined amount of the respective bulk material is drawn off from a plurality of storage containers, preferably arranged in a row, and fed via a removal belt to a common collecting belt which feeds the bulk material to a mixing device.
  • aggregates such as grit, lime, bentonite or the like.
  • the excavated earth is processed into a stable material, so that an otherwise necessary removal of the excavated earth from landfills can be dispensed with.
  • the invention is based on the object of designing a storage container for a bulk material in such a way that even poorly flowing bulk goods can be withdrawn in a meterable amount without problems.
  • the discharge tools moved by a drive ensure repeated destruction of the bridges formed, which disrupt the material flow, so that even difficult-to-flow bulk materials such as clay or loosened earth excavation can be drawn off in a continuous, determinable material flow.
  • the quality of the preparation of a stable paving material can be maintained within narrow limits by means of a mixing device. A standstill of the mixing device due to an added discharge opening is largely avoided.
  • the shaft In order to support the flow of the bulk material to the discharge opening, the shaft is moved back and forth by a predeterminable, adjustable angle of rotation, so that the working tools execute a corresponding pitch circle movement. It may be expedient to carry out a lateral movement in the axial direction of the shaft instead of or in addition to the pitch circle movement, for which purpose the shaft can be moved axially back and forth together with the working tools.
  • the drive is a piston-cylinder unit, which can carry out the back and forth movement in a simple manner via a corresponding hydraulic control device.
  • the work tools are preferably arranged in pairs, each work tool having a half-shell-like foot section which, together with the opposite foot section of the diametrically assigned work tool of the same pair, forms a common fastening shell.
  • the arrangement is such that one work tool of a pair protrudes into the storage container and the other work tool of the same pair protrudes into the discharge opening.
  • the other working tool expediently projects through the trigger opening with approximately half its radial length.
  • the cross section of the section of the shaft lying in the storage container is designed to deviate from the circular shape.
  • the section preferably has a rectangular, in particular square, cross section, the foot section of a work tool being designed to match the cross section in order to encompass it in a form-fitting manner.
  • the foot section is preferably provided in one piece with the working tool.
  • the storage container 1 shown in FIG. 1 has - as can be seen in particular from FIG. 3 - an essentially rectangular shape with longitudinal walls 2 and narrow walls 3 which - cf. 1 and 2 - run towards each other. This forms an upper feed opening 4, which is additionally determined by a collar 5 with a vertical side wall placed on the walls 2 and 3.
  • the feed opening 4 Opposite the feed opening 4 is a drain opening 6 whose passage cross section is significantly smaller than the passage cross section of the feed opening 4 due to the converging walls 2 and 3.
  • the width B of the discharge opening 6 corresponds to approximately one third of the width of the feed opening 4, while the length L of the discharge opening 6 has approximately two thirds of the length of the feed opening 4.
  • a draw-off belt 7 is arranged under the draw-off opening 6, the conveying direction 8 of which is oriented in the longitudinal direction of the storage container 1 (cf. FIG. 2), a housing 9 being provided between the draw-off belt 7 and the draw-off opening 6.
  • a similar or identical storage container 10 is adjacent in the longitudinal direction in the storage container 1, from which another bulk material emerges.
  • the quantities of bulk material dropped from various storage containers 1, 10 onto discharge belts 7 are fed from a collecting belt 33 (FIG. 1) to a mixer (not shown) in order to be intimately mixed with one another.
  • a mixer (not shown) in order to be intimately mixed with one another.
  • a stable filling material can be provided for filling work spaces, the loamy, releasable excavated earth is given to the storage container 1 and withdrawn from it in predetermined amounts in order to be fed to the mixer with the addition substances withdrawn from other storage containers 10.
  • a steady flow of bulk material from the storage containers 1, 10 is required.
  • a plurality of discharge tools 11 are provided, which are fixed to a shaft 12 which extends transversely to the extraction opening 6.
  • two shafts 12 are arranged parallel to one another at the same height; the arrangement of a shaft - e.g. B. running in the longitudinal direction through the discharge opening - may be sufficient.
  • Each shaft 12 is supported in the area of its end sections 13 in a bearing 14, the bearings 14 being held on a support frame 15 which surrounds the storage container 1 and is preferably fixedly connected to the storage container 1 on the narrow walls 3.
  • the carrier frame 15 lies in a plane between the feed opening 4 and the discharge opening 6, preferably at a small distance a from the discharge opening 6. Therefore, the axis of rotation 16 of the shaft 12 lies at a distance w from the plane of the discharge opening 6.
  • the shaft 12 projecting through the storage container 1 has a section 17 which has a shape deviating from the circular shape.
  • the section 17 preferably has a rectangular shape, in particular square cross section.
  • An outer angle plate 34 (Z plate) is arranged on the longitudinal wall 2 in the entry region of the shaft into the storage container 1, the axis of rotation 16 being perpendicular to the angle plate 34. This ensures simple sealing 18 of the shaft in the entry region of the longitudinal walls 2.
  • Dispensing tools 11, 11 ' are fixed on the section 17 of a shaft 12 which is square in cross section, wherein - as shown in FIG. 2 - each dispensing tool 11, 11' extends essentially in a straight line radially to the shaft 12 and is designed in a "paddle-like" manner.
  • These rod-like discharge tools 11, 11 ' have a half-shell-like foot section 19 which, together with a half-shell-like foot section 19' of a diametrically opposite discharge tool 11 ', forms a fastening shell 20 with which the discharge tools 11, 11' have a positive fit in the direction of rotation on section 17 of the shaft 12 be stuck.
  • the work tools 11 of adjacent shafts 12 are axially offset from one another. This increases the effectiveness of the trigger device.
  • a pair of discharge tools or a plurality of pairs of discharge tools can be arranged on a shaft 12.
  • At least one shaft 12 of the trigger device is provided with a drive 21, which in the exemplary embodiment shown is a piston-cylinder unit 22.
  • the cylinder 24 is supported on a stiffening frame 23 of the storage container 1, while the piston rod 25 engages on one end of a drive lever 26 which on one of the storage container 1 remote end 13 'of the shaft 12 is arranged in a rotationally fixed manner.
  • the drive lever 26 can also be designed as a coupling lever which is connected to a coupling rod 28 which engages with its other end on the drive lever 26 of an adjacent shaft.
  • the drive lever 26 and a coupling lever 27 for the coupling rod 28 are preferably arranged separately on the opposite ends 13 'of the shaft 12, as a result of which there is a uniform mechanical load. It may be expedient to arrange the drive 21 and the coupling rod 28 on one side of the storage container 1.
  • a back and forth movement of the discharge tools 11, 11 ′ can be achieved in order to achieve a predeterminable angle of rotation 30.
  • the angle of rotation 30 can advantageously be changed to such an extent that - seen in plan view - the working areas of the working tools 11, 11 'of adjacent shafts 12 overlap one another. If the desired discharge of a bulk material rather requires a kind of shaking movement, the work tools 11 can be moved back and forth at very high frequencies by very small angles of rotation. In this case, a movement advantageously takes place about a vertical starting position 31 of the working tools 11, 11 'parallel to the vertical axis 29 of the storage container 1. Another starting position, which deviates from the starting position 31, can also be set via the piston-cylinder unit 22.
  • the cylinder 24 of the piston-cylinder unit 22 is preferably a double-acting cylinder, so that a powerful reciprocating movement of the working tools 11 can be achieved in any position of the piston rod.
  • the one working tool 11 of a pair of tools extends into the storage container 1, while the other, diametrically opposite work tool 11 'extends to the trigger opening 6.
  • the distance w of the axis of rotation 16 of the shaft 12 and the radial extent E of a work tool are preferably matched to one another in such a way that the work tool 11 ′ projects through the trigger opening 6.
  • the working tool 11 ' preferably projects through the trigger opening 6 by approximately half the length.
  • the working tools 11, 11 ' can be moved back and forth on a pitch circle about the axis of rotation 16 of the shaft 12.
  • the movement in the direction of the angle of rotation 30 is oriented in the longitudinal direction of the storage container 1.
  • an additional drive 41 (FIG. 3) can be expediently arranged, which axially moves the shafts back and forth in the direction of the arrow 42.
  • This lateral movement given in the direction of the axis of rotation 16, can be superimposed on the partial circular movement of the working tools 11 or the shaft 12 or can be provided in their place.
  • adjacent shafts 12 can indeed be operatively connected to a coupling rod 43, the ends of the coupling rod 43 being articulated at the ends 13 'of the shaft 12.
  • the coupling rod 43 is preferably supported so that it can be pivoted halfway over a bearing 44 fixed to the housing.
  • the drive 41 consisting of a piston-cylinder unit can therefore be assigned to a shaft 12, the piston rod 45 acting on the end 13 ′ of the shaft 12.
  • the preferably adjustable stroke H is transmitted in the opposite direction to the adjacent shaft. Care should be taken to ensure that, when the swiveling ranges of the work tools 11 of adjacent shafts 12 overlap, the stroke H is adapted to the distance between the work tools.
  • the drive unit 41 instead of the swivel bearing 44 fixed to the housing, so that the shafts 12, which are connected to one another via the coupling rod 43, perform rectified lateral movements. This can be advantageous when equipping with a larger number of drive tools 11 and a small distance between the drive tools on a shaft 12.
  • the support frame 15 holding the bearings 14 of the shafts 12 can also be moved axially back and forth in the direction of arrow 40 relative to the storage container 1 in the plane of the shafts 12. If the cylinder 24 of the drive 21 is supported on the support frame 15, a relatively simple construction is possible since cardanic joints can be omitted.
  • a vibrator 50 is arranged on the outside of a wall 2, 3 of the storage container 1, which vibrates the wall or the storage container.
  • 1 vibrators 50 are preferably arranged on all four walls of the storage container, which is square in plan view (FIG. 1, FIG. 2).
  • the vibrators 50 can be arranged in the extraction device consisting of the shafts and the working tools; In the exemplary embodiment shown, they are arranged in addition to the extraction device and make the foot sections of a bulk material bridge that is supported on the wall 2, 3 difficult or destroy.
  • the vibrators 50 preferably lie on the side of the shafts 12 facing away from the discharge opening 6 a short distance from their axes of rotation 16.
  • the vibrators 50 can expediently be designed as electrical eccentric motors or the like, the electrical control of which takes place via a common control device. This enables targeted vibration excitation of individual or - z. B. out of phase - all walls 2, 3.
  • the shaker 50 actively supports the removal of the hard-flowing bulk material from the storage container 1.
