Definitions

  • the deflecting flap is positioned outwardly from the discharge end of the pipe line and extends in a downwardly inc1ined fashion so that its surface extends into the path of the material flowing from the pipe line. Further, the deflecting flap is not, only rotatable about the axis of the discharge end of the pipe line but is angularly displaceable relative to the pipe line axis for varying the manner in which the material is directed from the flap.
  • 3. pair of wind wheels are provided in the path of the discharge end of the pipe line on opposite sides of the discharge axis, and motion transmission means are connected between the wind wheels and the deflecting flap. The wind wheels are pivotally supported so that they can be arcuately displaced outwardly from the axis of the discharge end of the pipe line.
  • the present invention is directed to an apparatus for uniformly distributing the material flowing from the discharge end of a blower pipe line and, more particularly, it concerns an arrangement where at least one wind wheel is pivotally mounted in the path of the discharge from the pipe line and is operatively connected to a deflecting flap for rotating the flap about the discharge axis of the pipe line and also for displacing the flap angularly with respect to the discharge axis.
  • Apparatus for distributing the material from a pipe line are known and are available under the name of .End Distributors.
  • One such device is disclosed in Austrian Pat. No. 227,165.
  • the rotation of the deflecting flap about the axis of the blower pipe line is effected by a wind wheel which revolves about an axis of rotation disposed parallel to the flow from the pipe line and, further, the wind wheel is in operative connection with the reduction gear which, in turn, drives friction rollers in engagement with a rim member.
  • the wind wheel revolves below the discharge opening and passes beneath the outside of the bend at the discharge end of the pipe line, the wind wheel is rotated at a very high rate and, as a result, transmits driving power at a relatively high level.
  • the amount of air and material cause it to be driven at a relatively slow rate and to transmit relatively little driving power. Therefore, in practice the end distributor frequently stops when the wind wheel is in the position corresponding to the inside of the discharge bend in the pipe line. With the defleeting flap stopped in this position it is difficult for the deflector flap to commence working again when the and, similarly, leave the space below the discharge end i in the same manner.
  • the hinge of the deflecting flap is positioned under the outside of the bend in the discharge end of the pipe line, the major part of the material strikes the upper end of the flaps and, as a result, is deflected in an aerodynamically favorable manner in the desired direction along the entire deflecting space without experiencing major deceleration.
  • the hinge of the defleeting flap is positioned, for example, under the inside of the bend of the discharge end of the pipe line, the mass of the material being conveyed strikes the center on the portion of the deflecting flap which is especially curved with the result that the material is deflected in an aerodynamically unfavorable manner and is also decelerated to a. greater degree.
  • Such an arrangement results in a reduced throwing range for the deflector.
  • the primary object of the present invention to provide an arrangement where the abovementioned disadvantages are avoided and a uniform distribution afforded to the material flowing from the discharge end of a blower pipe line. It is important that the end distributor should be light weight and easy to handle, so that it can be operated reliably and uniformly by one person under all operating conditions by the driving action obtained from the material flow and air current passing from the discharge end of the pipe line. Furthermore, the end distributor of the present invention should disperse the material in a uniform manner between the center and edge of the stone surface even when the discharge end is located adjacent a bend in the pipe line.
  • a pair of wind wheels are arranged in front of the de- 1 flecting flap and extend into the path of flow from the discharge end of the pipe line for distributing the material in a uniform manner.
  • the deflecting flap is rotated about the axis of the discharge opening from the pipe line by at least one of the wind wheels.
  • the transmission of the driving action of the wind wheels is transmitted to the deflecting flap through a reduction gear and, while rotating, the flap can be displaced into various positions relative to the discharge axis of the pipe line.
  • Both of the wind wheels are arranged in operative connection with the reduction gear.
  • the wind wheels For operation over the range of material flow from the pipe line it is preferable for the wind wheels to be mounted on pivotally arranged pendulum arms.
  • Another characteristic of the present arrangement is the rotation of the wind wheels in opposite directions with one wind wheel each being connected to one end of an inlet shaft for the reduction gear.
  • the wind wheels are connected over flexible drive shafts so they are each connected to an opposite end of a drive shaft for the reduction gear.
  • the axes of rotation of the windwheels are substantially parallel to one another and are positioned perpendicularly to the axis of the discharge from the pipe line.
  • the hinge axis for the deflecting flap is, desirably, arranged substantially normally to the axes of rotation of the wind wheels.
  • Another characteristic feature of the invention is the spring loading on the pendulum arms so that they are biased in the direction of the axis of the discharge from the pipe line and are provided with adjustable stops for varying the distance between the wind wheels and the discharge axis.
  • Yet another favorable feature of the invention is the arrangement of the driving pinion for the rotation of the deflecting flap so that it can be selectively engaged and disengaged.
  • the pinion When the pinion is used for driving the deflecting flap it provides for the rotation of the flap through 360, however, it can be replaced by a feed pawl assembly which effects a reciprocating swivel movement of the deflecting flap about the axis of rotation with the range of movement being, for example, 90, 180, or 255.
  • Still another feature of the invention is the manner in which the deflecting flap is shaped as a curved trough with its lower or free end located outside of the downward projection of the path from the discharge end of the pipe line so that only those portions of the deflecting flap which are sharply inclined to the discharge axis are aligned below the discharge outlet from the pipeline.
  • Yet another important characteristic of the invention is the eccentric arrangement of the support for the deflecting flap relative to the discharge axis from the pipe line.
  • the axis of rotation for the deflecting flap and the discharge axis from the pipe line are disposed in parallel relationship and the axis of rotation is positioned between the discharge axis and a plane parallel to the discharge axis and passing through the outer surface of the bend at the discharge from the pipe line. Due to the eccentric arrangement mentioned above, it is possible to uniformly distribute the material from the pipe line even though it is irregularly distributed from the pipe line discharge. Because of the arrangement of the defleeting flap, the material strikes the flap in approximately the same position as it rotates so that equal throwing ranges for the material are achieved in all directions.
  • brackets are secured on a fastening arrangement positioned at the discharge end of the pipe line and one of the brackets is longer than the other so that with the outer ends of the brackets connected to the gear rim on which the support arrangement rotates it is possible to maintain the eccentricity between the discharge axis of the pipe line and the axis of rotation of support means for the deflector flap.
  • At least two brackets are provided each with an upwardly directed bolt having a knurled member at its upper end and the bolts are engageable within slots in suspension straps secured to the retaining clamp at the outlet end of the pipe line so that the support arrangement can be easily and simply adjusted relative to the diameter of the pipe line.

  • Each of the straps 4 has a slot 47 into which a bolt 30 is fitted for securing the end distributor 45 onto the end of the pipe line 1.
  • Knurled caps 3 are threaded onto the heads of the bolts 30, so that it is not necessary to completely remove the caps in mounting the distributor on the pipe line.

  • Outwardly from the ring mount 7 is a gear rim 16 having an inwardly projecting bearing surface 32 which extends into the grooves in the rollers. Due to their engagement with the bearing surface 32, the rollers roll along the rear rim and hold the end distributor 45 in position in both the axial direction, that is against movement in the upward and downward direction, as well as in the radial direction so that the end distributor can rotate easily about its axis of rotation 34.
  • the end distributor is ecentrically mounted about the discharge end of the pipe line and its axis of rotation 34 is offset from the discharge axis 33 of the pipe line.
  • the entire revolving assembly of the end distributor 45 is supported from the ring mount 7 and a guide trough l3 embraces a part of the circumference of the ring mount.

  • the sensing roller 29 is always maintained in contact with the cam 26 so that no additional biasing means are required, at least not in the represented position of the end distributor 45.
  • the cam acts against the roller deflecting it downwardly and, as a result, the pressure bar is also deflected downwardly pushing against the bracket 46 of the deflecting flap with the results that the flap I5 is pivoted about its axis 41 so that its outer free end tends to move upwardly.
