Definitions

  • the present invention relates to a spreader, by means of which granular or particulate material can be applied to a substrate.
  • a scattering device can be used to apply in one of the last operations in the production of asphalt surfaces debris and then incorporate it by means of a compactor, so for example an asphalt compactor roller in the near-surface area.

  • debris By providing debris in the near-surface area, the grip for moving vehicles can be increased.
  • the spreader in the winter service spreading chips or possibly salt.
  • Another application is the application of granular or particulate material, such. As fertilizer or seeds, in agriculture.
  • scattering devices with a rotating spreading plate
  • the material to be spread is applied from above onto the rotating spreading plate provided, for example, with conveying blades.
  • the spreading material is accelerated by the conveying blades in the circumferential direction. Due to the resulting centrifugal forces, the grit is thrown radially outward and thus distributed on the ground.
  • a comparatively large spread can be achieved, which can significantly exceed the width of the scattering device per se or a vehicle carrying the scattering device, a homogeneous scattering pattern, as is required in particular when applying grit on the surface of an asphalt surface , can not be reached.
  • an elongated, slot-like litter discharge opening is provided on the underside of a litter receiving container, for example. Through this opening, the litter material is discharged down, including in the Inside the litter material receiving container conveying members, such. As fan-like conveying wheels, may be provided, through which a defined setting of the dispensed through the litter discharge opening through the amount of litter material is possible. With such a structure, a more homogeneous scattering pattern can be produced, although the scattering width is limited essentially to the width of the scattering device or the scattering material receiving container.
  • a spreader in particular for spreading out litter, comprising a litter material receptacle with a discharge opening arrangement for dispensing litter down, wherein at least one obliquely baffle positioned opposite to the vertical direction is disposed below the discharge opening arrangement.
  • the present invention basically uses a structure with a litter material receiving container and a discharge opening arrangement, through which the litter material is discharged down onto the substrate to be spread, thus not a rotating spreading plate or the like. Since, according to the invention, an obliquely positioned baffle plate is arranged below the discharge opening arrangement, the spreading material dispensed downwards by the discharge opening arrangement does not fall directly onto the substrate, but first onto the baffle plate, whereby, after hitting the baffle plate by its inclination, the material spreads obliquely downward the surface of the baffle moves.
  • the discharge opening arrangement and the at least one baffle plate are elongated in an opening longitudinal direction.
  • the present invention utilizes the effect that the scattering material incident on the baffle plate not only obliquely moves downward along the baffle but is also spread transversely to this direction of movement. This effect can also be used to increase the spread. According to the invention, it can be provided for this purpose that, in at least one opening end region of the discharge opening arrangement situated in the opening longitudinal direction, the at least one deflection plate extends beyond the discharge opening arrangement in the opening longitudinal direction.
  • the dispensing opening arrangement comprises a plurality of dispensing openings which follow one another in the opening longitudinal direction.
  • a large number of discharge openings leads, with a high degree of homogeneity of the distribution of the emitted litter material, to a stable construction with easy influenceability of the litter discharge quantity.
  • the at least one baffle plate is mounted in a fixing edge region on the scattering material receptacle and extends obliquely downwards from the attachment edge region.
  • the at least one baffle plate completely overlaps the discharge opening arrangement transversely to the opening longitudinal direction.
  • the baffle plate be positioned below the discharge opening arrangement in the vertical direction with a section closer to the fastening edge area.
  • the at least one baffle plate can be made of sheet metal material.
  • the at least one baffle plate is curved in a discharge edge region and / or at least one end edge region.
  • the at least one baffle plate is at least partially formed like a sieve with a plurality of scattering material passage openings.
  • the at least one baffle plate in their entire litter material receiving area formed like a sieve more advantageously, the cross-sectional dimensioning of the litter material passage openings is tuned to the chandelierde litter material that even the largest expected particles can pass through these litter material passage openings.
  • the invention further relates to a self-propelled compacting device, in particular an asphalt compactor, with a spreading device constructed according to the invention.
  • the in the Fig. 1 to 3 Spreader 10 shown includes a stray material receptacle, generally designated 12. This can be funnel-like widening and open on its upper side 14 in order to be able to apply the scattering material to be applied to a substrate from above into the litter material receiving container 12.
  • a stray material receptacle generally designated 12. This can be funnel-like widening and open on its upper side 14 in order to be able to apply the scattering material to be applied to a substrate from above into the litter material receiving container 12.
  • At the litter material receiving container 12 for example, in the four corner regions of the same support legs 16, 18, 20, 22 may be provided to the spreader 10, for example, when it is not in operation, to be able to park on the ground.
  • a litter discharge opening assembly 26 provided which in Fig. 1 symbolically shown with a dashed line.
  • This discharge port assembly 26 may include a continuous discharge port, but preferably a plurality of discharge ports, and is elongated in an opening longitudinal direction L which is in Fig. 1 is orthogonal to the plane of the drawing and substantially corresponds to the width direction of the spreader 10.
  • various, e.g. B. fan-like conveying members may be provided, which ensure in the scattering operation that contained in the interior of the litter material receiving container 12 scattering material is conveyed in a defined amount down toward the discharge opening 26. It could also be used solely for the gravity acting on the litter material.
  • the opening cross section of the discharge opening / s can be varied by a slider.
  • Recognizable access flap 28 can be obtained in the lower area access to the interior of the litter receiving container 12.
  • About one in Fig. 2 recognizable, for example, manually adjustable actuating mechanism 30, a provided on the bottom 24 in the region of the discharge opening 26 slide 32 can be adjusted or moved, for example, to change the opening cross section of the discharge opening 26 and thus also be able to influence the amount of the emitted litter material.
  • a plurality of mounting portions 34, 36, 38 in which the scattering device 10 on a vehicle, so for example, a asphalt compactor, a winter service vehicle or a tractor or the like, can be attached.
  • a baffle plate 40 which is continuous in the opening longitudinal direction L, that is designed to be uninterrupted in the example shown, is arranged. This is in a fastening edge region 42, for example by a plurality of also fixed to the litter material receiving container 12 mounting brackets 43rd fixed to the underside 24 of the litter receiving container 12 and extending from the attachment edge portion 42 toward a discharge edge portion 44 obliquely downward. It should be noted here that the fastening edge region 42 and the discharge edge region 44 in the particular in Fig. 2 recognizable elongated configuration of the baffle 40 each form the long side edge portions of the baffle 40.

  • the litter material emitted downward from the discharge opening arrangement 26 in the vertical direction V advantageously impinges on the deflection plate 40 in a surface area closer to the attachment edge region 42. Due to the inclination of the baffle plate 40, the litter material moves on its surface obliquely downward in the direction of the Abgaberand Scheme 44. In this movement obliquely downward and a homogenization of the distribution of the scattering material is transverse to this direction of movement, ie in the opening longitudinal direction L, achieved or supported.
  • successive individual particles of scattering material pass through the scattering material passage openings 50 and impinge under the deflection plate 40 on the substrate to be spread.
  • baffle plate in the opening longitudinal direction advantageously in both end regions, ie in each case where the side edge regions 46, 48 are formed, on the discharge opening 26 or whose ⁇ Stammsend Schemee survives, is due to the effect that on the Baffle 40 incident scattering material will also be distributed in the opening longitudinal direction L, accompanied by the achievement of a more homogeneous scattering image, an increase in the spread reaches.
  • the scattering behavior and thus also the achievable scattering pattern can be influenced by various technical measures in the context of the present invention.
  • the dimensioning or the positioning of the scattering material passage openings 50 has a significant influence on the distribution behavior.
