Definitions

  • the invention relates to a vehicle mixer for flowable media, such as concrete, with the features of the preamble of claim 1.
  • Such a vehicle mixer is known from US-A-2,303902.
  • the closure element consists of a pipe socket of the feed funnel and projects axially into the drum mouth.
  • the central tube is only provided in the rear end area of the drum and is attached to radial arms of the drum.
  • a sleeve passes through the feed hopper and is slidably mounted on the tube.
  • the short pipe attached on one side cannot support the feed hopper without vibration. Vibrations of the pipe lead to leaks in the area of the ring seal between the drum mouth and the closure element.
  • the permanently installed pipe is an obstacle for maintenance work inside the mixing drum.
  • the object of the invention is to improve the storage of the closure element of the mixing drum in order to complete the seal.
  • the assembly which includes the closure element and the tube, preferably also the feed hopper, can be removed as a whole from the drum and retracted, which simplifies maintenance work.
  • the at least two rotary bearings in the drum are preferably arranged near the drum ends, thus ensuring low-vibration support of the closure element with the feed hopper on the drum even with large static and dynamic loads. This is for one Uniform, good sealing of the closure element on the drum mouth is crucial.
  • a particularly advantageous development of the invention is to be seen in the fact that the tube is given an additional function thanks to a pressurized water connection and a number of water outlet nozzles in the interior of the drum.
  • the recipe-related mixing water quantity can be metered into the dry concrete mix very effectively.
  • the water is distributed more evenly and quickly. It is preferred that the majority of the nozzles jet obliquely and vertically upwards. Therefore, the majority of the nozzles are preferably located in the upper half of the tube.
  • Another embodiment of the invention is that removable wear sleeves are arranged on the tube in the area of its bearings in the mixing drum. In conjunction with the pressurized water feed into the pipe, this wear protection can now be easily cleaned and lubricated with leakage water from the pipe. This extends the lifespan.
  • the nozzles in the tube are preferably self-sealing and equipped with an exchangeable wear protection.
  • a mixing drum 16 On a vehicle frame 10 there is a bearing block 12 with rollers 14, on which a mixing drum 16 is rotatably mounted via a running ring 18 in the rear area of the mixing drum.
  • the mixing drum 16 has a rear drum mouth 20 which is delimited by an annular flange 22.
  • the mixing drum 16 At the opposite front end, the mixing drum 16 is closed and has a central pin, not shown, which is used for storage and for the rotary drive.
  • the mixing drum is state of the art.
  • a coaxial tube 24 is arranged in the interior of the mixing drum and is mounted so as to be relatively rotatable and axially displaceable by means of a front bearing 26 and a rear bearing 28.
  • the two bearings 26, 28 are held by means of star-shaped arms 30 on the or the peripheral spirals 32 of the mixing drum 16.
  • the bearing shells of the bearings 26, 28 have a larger inner diameter than the outer diameter of the tube 24.
  • wear sleeves 34 which are exchangeably fastened on the tube 24.
  • the pipe 24 protrudes from the drum mouth 20 and carries at its end a rigidly fastened closure element 36 which comprises an annular wall 38 with an annular seal 40 and a feed funnel 42 which is penetrated by the tube 24.
  • a U-bracket 44 is attached to the tube end and is welded to the side walls of the feed funnel 42. From the bracket 12, two support arms 41 extend upwards, on one of which a torque support 46 is fastened, which is designed in such a way that it prevents the feed hopper 42 from pivoting about the drum axis, without, however, transmitting relative movements between the drum and undercarriage to the hopper 42 . On a transversely extending yoke 48 of the bracket 44, two pressure medium cylinders 50, 52 engage, which lie in an axial plane of the drum 16 and have their counter bearing according to FIG. 4 on the support arms 41 or according to FIG.
  • a bearing yoke 54 which is relative is rotatably mounted on the rim 18 of the mixing drum 16 and is secured against rotation with the drum 16 by means of a rotation prevention device 56.
  • the bearing yoke 54 has a plurality of rollers, which are supported on the running surface of the running ring 18, and rollers lying at right angles thereto, which touch the running rim on both end faces.
  • the bearing yoke 54 thus forms an abutment for the actuating cylinders 50, 52, which thus do not exert any forces on the closure element due to deformations of the vehicle frame, which results in a perfect sealing of the drum even while the vehicle is traveling.
  • the structural unit consisting of closure element 36, feed funnel 42 and tube 24 is axially adjusted and moves from the open position shown in FIG. 1 to a closed position in which the ring seal 40 is located on the ring flange 22 Mixing drum 16 creates.
  • the annular wall 38 of the closure element 36 has a forward-facing nozzle 58, which is smaller in diameter than the ring seal 40. This connecting piece 58 engages in the interior of the drum 16 and protects the ring seal 40.
  • the tube 24 protrudes from the funnel 42 and has a pressurized water connection 62 at the projecting end, to which a pressurized water hose can be connected.
  • the tube 24 is provided along its entire length in the area of the mixing drum 16 with axially spaced outlet nozzles 64, most of the nozzles being arranged in the upper half of the tube 24 and pointing upwards. Mixing water can thus be metered into the dry concrete mixture evenly distributed over the entire length of the drum via the pipe 24.
