Definitions

  • ABSTRACT A frame mounting a pair of rotatable rollers forming a June 16, 1971 Germany ..P 21 29 840.8 seat for a cylindrical drum containen Means for receiving the drum after mixing and means for lifting [52] U.S.Cll ..259/89, 259/81 the drum from the rollers into the receiving means ⁇ 2 23: 0 ⁇ with the axis of the drum maintained in parallel relationship to the axis of the rollers.
  • the present invention relates to cylindrical drum mixing apparatus particularly adapted for the mixing of such missible materials as sand, concrete, plaster of paris, cement and similar articles.
  • containers of this type are cylindrical, hollow drums which are adapted to rest on one or more rollers which are driven to effect rotation.
  • one of the rotating rollers may be driven in order to assist the attendant in rolling the container off of the mixing device.
  • the degree of friction existing between the container and the rollers determines the ease at which the attendant is able to manipulate the container. Notwithstanding this, the lifting of the drum and its removal from the drive mechanism calls for an exceptionally large physical exertion since the relatively large size of the drum and its heavy weight in a filled condition does not make the task simple.
  • apparatus for mixing materials such as sand, concrete and the like comprising a frame on which a pair of elongated rollers are mounted.
  • the rollers are arranged in parallel spaced relationship in order to create a seat for a drum container which receives the material to be mixed.
  • At least one of the rollers is positively driven by conventional means to rotate the container about an axis parallel to the axis of the rollers.
  • Means are mounted adjacent to the front of the frame, transversely of the rollers to receive the drum container after the completion of the mixing operation comprising a carrier in which the drums may be rotatably seated.
  • Means are provided for mechanically lifting the drum container from its seat on the rollers and transporting it to the carrier.
  • the mixing apparatus is generally defined by the numeral 10 and comprises an elongated chassis frame formed from a plurality of upright beams 12 and a number of elongated cross connecting beams 14.
  • a pair of cylindrical roller shafts 16 are arranged across the length of the chassis on the lower pair of cross beams 14, parallel but transversely spaced from each other to form a saddle-like supporting seat for a pair of mixing drums 18, 19 (seen in dot-dash lines).
  • the length of the frame and rollers 16 is chosen to accommodate a multiple number of containers which if desired may be more than the two shown.
  • the drums 18, 19 are axially aligned with each other and thus provide two stations containing drums which may be simultaneously rotated.
  • Each of the drums 18, 19 are formed with end caps, being radially extending flange-like bogey wheels 20 and a hollow cylindrical container portion 22 therebetween. Extending outward along the central axis of the drum of the bogey ends is a supporting bearing pin or spindle post 24.
  • the cylindrical portion 22 is provided with an appropriate door or flap mechanism having a suitable latching or fastening means through which the material to be mixed may be inserted and removed prior and after the mixing operation.
  • a carrier Arranged in front of the chassis of the mixing apparatus is a carrier, generally designated by the numeral 30, supported on a movable table generally designated by the numeral 35.
  • the supporting table comprises a flat rectangular based plate 40 inclined downwardly toward the chassis of the mixing apparatus.
  • the plate 40 is secured to a pair of transversely extending bracket arms 54 which are supported in a manner to be described later below, and transversely of the rotating rollers 16.
  • the carrier 30 comprises a pair of transversely spaced vertical wall plates 32 and 34 joined at their rearward end by a wall 36. Both vertical wall plates 32 and 34 are similar to each other having an upper forward edge 42 inclined upwardly away from the chassis and in which are formed a pair of arcuate receiving grooves or half bearing portions 46, 48 which are adapted,as will be described later, to receive the bearing pins 24 of each of the drums l8 and 19.
  • the vertical wall plates 32 and 34 are spaced apart from each other a distance conforming to the outer linear distance of each of the drums 18, 19 so that when the drums are placed thereon the container drums l8 and 19 may easily revolve about the pins 24.
  • a generally flat ledge 72 Joining the forward edge of the retaining plates 32 and 34 is a generally flat ledge 72 which is inclined slightly rearwardly and downwardly from the chassis of the mixing apparatus.
  • the ledge 72 provides a flat deck on which the drum containers may rest and roll as they are being shifted from the rotating rollers 16 to their position in the bearing grooves 45 and 48. This is shown in the dot-dash line in FIG. 2.
  • the bracket arm 54 is supported within the chassis frame by a pair of upwardly extending roller arms 60 and 62 on which there are mounted roller runners 64 and 66 respectively.
  • the runners are held and guided in rails 68 and 70 respectively which themselves are fastened to the lower cross connecting beams 14 below the roller shafts 16.
  • the supporting table 35 for the carrier 30 is designed to have a width corresponding to one of the drums 18-19, the parts of the carrier itself being all correspondingly formed to receive just one drum.
  • the supporting table is thus movable within the guide rails 68-70 so that it can be shifted along the length of the chassis between a position in front of either one of the drums; consequently, either one of the drums may be selectively removed from their seated position of the rollers 16 into the carrier frame 30.
  • the resting ledge 72 provides the transfer means between the chassis and the carrier 30 on which the container is rolled.
  • a drum lifting mechanism generally designated by the numeral 74 is provided for lifting the drums 18 or 19 out of its seat in the saddle formed by the rollers 16 and 18.
  • the drum lifting mechanism is mounted on the bracket 54 so that it too is shiftable with the supporting table 35 into position in front of either one of the drums 18 or 19.
  • the lifting mechanism 74 comprises a frame formed of a pair of parallel lever arms 76 and 78 connected at its forwardmost position under the rollers 16 by a crosspiece 80 and at its rearmost position under the supporting table 35 by a foot pedal piece 82.
  • the double lever arms 76, 78 are each pivotally connected to their associated bracket 54 by a bolt 84, 86 respectively, located midway along their length.
  • each of the lever arms 76 and 78 there is provided a substantially vertical angle piece 88 or 90 respectively.
  • the angle pieces 88 an 90 extend upwardly between the roller shafts 16 preferably just forward of the rearmost roller 16.
  • Each of the angle pieces 88 and 90 supports a propping roller 92, 94 respectively, each of which is adapted to engage the periphery of the spaced bogey wheel flanges 20 of either of the container drums 18 or 19.
  • a refuse receiving tray is located in conventional manner below the operation equipment in line with the rotating drums in order to receive any refuse which may inadvertently fall from the drums as the material is being mixed.
  • empty drums 18 and 19 are placed in their seated position on the rollers 16 and thereafter a suitable number of materials to be mixed is inserted therein.
  • the rollers 16 are driven in conventional manner and the material within the containers are thereby mixed by causing the rapid rotation of the containers l8 and 19.
  • a carrier mechanism is placed over the supporting table 35 and the table and carrier are aligned along the length of the mixing apparatus in front of the selected one of the drums 18 or 19 to be emptied.
  • the operator then depresses the foot pedal -bar 82, pivotting the lifting mechanism 74 so that the rearward angle brackets 88 and 90 move upwardly between the rollers 16.
  • the carrier mechanism 30 may be removed and the mixed material may be delivered to the site at which it is to be used and removed from the mixing drum.
  • a carrier 30 is then replaced on the supporting table 35 and the supporting table and carrier and lifting mechanism all are moved axially along the drame into position in front of the other one of the mixing containers. It will thus be seen by alternating the placement of empty containers and the removal of full containers from the apparatus that a sequential operation may be effected wherein a continuously mixing operation is underway at all times.
  • Apparatus for mixing comprising a frame, a pair of rotatable rollers mounted on said frame, said rollers being arranged in parallel spaced relationship to form a seat therebetween for receiving a drum container thereon with its axis parallel to the axis of the rollers, means for rotating at least one of said rollers to thereby effect the rotation of said drum, a carrier mounted to the frame in front of said rollers for receiving said drum and means for lifting said drum from said rollers and causing said drum to roll with its axis parallel to said rollers on to said carrier.
  • said carrier means comprises a pair of vertically spaced walls connected by a transverse member at its forward and rear end, the upper edge of each of said walls being provided with at least one bearing groove, said containers having extending shafts adapted to be received by said grooves.
  • the forward connecting member comprises a ledge inclined downwardly to the forward portion of said carrier whereby said container may be made to roll over said plate onto said bearing grooves.
