Definitions

  • the invention relates to a material feed container for a slurry pump according to the preamble of claim 1.
  • a material feed container for thick matter pumps which has an upwardly open container bottom part and a container attachment releasably connected thereto via a flange connection.
  • the peripheral upper edge of the container attachment limits the material feed opening.
  • an agitator is mounted, the bearings are in an open-edged recess of the container base, so that the agitator is easily replaceable after removal of the container attachment.
  • the container attachment forms a hopper for thick matter, such as concrete.
  • the filling of the concrete is usually carried out in that a truck mixer approaches the material supply container and fills the concrete via a channel in the material supply container.
  • the container attachment must be made of sturdy sheet metal. This requires a high weight, so that the container attachment can not be easily removed by hand.
  • Material feed container according to EP 1 076 596 B1 have in the delivery cylinder openings intermediate rings as wearing parts that protect the belonging to the container end wall inner surface of the delivery cylinder opening from wear by flowing concrete. These intermediate rings must be replaced regularly due to wear. Since the intermediate rings are inserted from the delivery cylinder side into the delivery cylinder opening, the delivery cylinder must first be removed from the container end wall for mounting and dismounting. This is expensive.
  • a material supply container having the features of the preamble of claim 1 is known. It has a hinged lid for covering the material feed opening.
  • a vehicle engine cover which has a hinged hood with a cover part made of a plastic wall.
  • a tiltable engine cover for trucks which consists of glass fiber reinforced plastic.
  • the engine cowling has glued-on reinforcing ribs on its inside.
  • the solution according to the invention is based on the idea that a hinged lid covering the material feed opening and articulated on a container wall is easier to clean than a conventional hinged lid made of sheet metal. Thick material, especially concrete, adheres much less to plastic than to sheet metal.
  • the hinged lid is designed as a hollow plastic body with a first plastic shell facing the material feed opening and a second plastic shell which preferably integrally connects to the latter and forms a top side of the lid.
  • a plastic hollow body is relatively stable with low weight. This is particularly advantageous when the hinged lid is hinged to the container attachment and must be removed together with the container attachment for maintenance work inside the container.
  • the first plastic shell may have a smooth surface facing the material supply opening.
  • the second plastic shell has stiffening beads. This gives the hinged lid increased stability.
  • the hinged lid is advantageously made in one piece by a Rotationsg tell Kunststoff.
  • the hinged lid expediently has handles, which are preferably integrally formed. Furthermore, it expediently has hooks, in which fastened to a container wall closure elements can be hooked. The hooks are preferably integrally formed on the hinged lid.
  • the hinged lid is preferably connected by at least one hinge and at least one gas spring with the container end wall. The gas spring facilitates the opening of the lid. Near its side connected to the container end wall, the hinged lid on the first plastic shell expedient attachment means for a rubber apron. This hangs down from the hinged lid into the material feed opening and prevents thick material from flowing into the gap between the hinged lid and the container end wall.
  • the advantageous development according to claim 9 is based on the idea that it requires less effort to mount the intermediate rings on the inside of the container and dismantle as over the container outside. This avoids that when replacing the intermediate rings, the delivery cylinder must be disconnected from the material supply container. An intermediate ring is inserted over the container interior into the delivery cylinder opening by the cam is pushed on its outer surface in the bayonet opening and the intermediate ring is then rotated about its longitudinal axis, so that the cam is inserted into the inner groove.
  • the mounting of an intermediate ring on the container interior is particularly advantageous when the material feed container, as described above, is formed in two parts. By removing the relatively light container top the inside of the container is easily accessible.
  • the advantageous development according to claim 15 is based on the idea to make the interior of the material feed container for maintenance personnel easier to access by having an easily demountable and removable container attachment on the end wall side.
  • the container top does not extend to the rear wall which faces the approaching truck mixer.
  • the peripheral edge delimiting the material feed opening has, on the rear wall side, an edge part belonging to the container lower part.
  • the container attachment is thus protected against damage by the truck mixer. It must therefore not be designed as stable as the container base and can have a relatively low weight.
  • Fig. 1 shown in the drive state truck concrete pump has a chassis 10, a front-side cab 12, a mounted on a pivot bracket 14 of the chassis 10 concrete distribution boom 16 and arranged on the chassis 10 two-cylinder slurry pump 18.
  • the arranged in the rear part of the chassis 10 material feed container 20 has in its end wall 22 delivery cylinder openings 24 through which two delivery cylinder 26 of the slurry pump 18 are connected.
  • a discharge nozzle 30 At the end wall 22 opposite the rear wall 28 of the material feed container 20 is a discharge nozzle 30, to which a delivery line 32 is connected.
  • S-tube diverter 34 In the interior of the container is a here formed as S-tube diverter 34, which is connected at one end to the discharge nozzle 30 and the other end alternately about the axis of a pivot shaft, not shown, by hydraulic means in front of the two delivery cylinder openings 24 is pivotable.
  • the material feed container 20 (FIG. Fig. 2 ) is divided into a container bottom 38 and a container top 40.
  • the end wall 22 and the side walls 42 connecting the end wall 22 to the rear wall 28 are divided into two upper and one lower parts.

  • the container lower part 38 has, in addition to a bottom 54 and the rear wall 28, a lower end wall portion 56 and lower side wall portions 58.
  • the lower side wall portions 58 drop obliquely from the lower end wall portion 56 and carry a second flange 60 complementary to the first flange 50.
  • the two flanges 50, 60 are connected in a simple manner by means of screws 62. Between them, a rubber seal can be arranged so that the container base 38 and container attachment 40 can be assembled in a simple manner to the material supply container 20.
  • the material supply container 20 has an upwardly facing material feed opening 64, which is delimited by a peripheral edge 66, 68.
  • the peripheral edge is divided into two edge parts 66, 68.
  • the first edge portion 66 is formed by the upper edge of the upper end wall portion 44 and the upper side wall portions 46. It is followed by the second edge part 68, which is formed by the upper edge of a rubber apron 70. This is attached to the container base 38 and protrudes beyond the rear wall 28 and extending from the rear wall 28 away portions of the lower side wall portions 58 out.
  • the two edge parts 66, 68 are aligned.
  • the container base 38 In the container base 38 bearing openings 72 are arranged in the side walls 42, which serve to receive bearings of a stirrer. In the rear wall 28, a rear wall opening 73 is arranged, via which the pipe switch 34 can be connected to the discharge nozzle 30. In the lower end wall portion 56 are the delivery cylinder openings 24 for connecting the delivery cylinder 26.
  • the container base 38 is made of sturdy, thick-walled sheet steel. Only forces acting on the container top 40 from the filled into the material supply port 64 concrete originate. Its stability is therefore much lower requirements.
  • the container base 38 has over the lower end wall portion 56 projecting tubular support elements 74 for a grid.
  • the grate can also be placed on a support bead which is provided on the container top 40.
  • the material supply container 20 is attached via hangers 76 on the chassis 10.
  • a connection plate 80 is attached to the end wall 22 for connecting the delivery cylinder 26.
  • a spectacle plate 82 is releasably attached ( Fig. 4 ) whose spectacle plate openings 84 communicate with the delivery cylinder openings 24.
  • the spectacle plate 82 projects beyond the conveying cylinder openings 24 and thus forms a stop for an intermediate ring 86 in the direction of the container interior.
  • the intermediate ring 86 extends in the axial direction over the delivery cylinder opening 24 extending through the end wall 22 and the connection plate 80. Its inner surface delimits one Throughflow 88 for the thick material.
  • the outer circumferential surface 90 of the intermediate ring 86 carries three arranged at an angular distance of 120 ° cam 92.
  • the intermediate ring 86 in its lateral surface 90 has two axially opposite the cam 92 offset circumferential grooves 96, are inserted into the sealing rings 98 for abutment against the end wall 22 and the connection plate 80.
  • Another circumferential groove 96 is located in the end face of the intermediate ring 86 facing the spectacle plate 82.
  • the sealing ring 98 contained in it bears against the spectacle plate 82.
  • the spectacle plate 82 is first unscrewed. Subsequently, the intermediate ring 86 is rotated about its longitudinal axis until the cams 92 can be pulled out of the bayonet openings 95. For this purpose, the intermediate ring on its end face recesses 100 for insertion of holding thorns. Between the intermediate ring 86 and the end wall 22, a circumferential cavity 102 is also arranged, which is fillable via a feed opening 104 with grease. The cavity 102 increases upon withdrawal of the intermediate ring 86 from the delivery cylinder opening 24 in the direction of the container interior. Thus, the injection of grease through the feed opening 104 facilitates the removal of the intermediate ring 86. The grease also acts as a lubricant, which facilitates the rotation of the intermediate ring 86. In general, the wear parts spectacle plate 82 and intermediate ring 86 are replaced together.
