Definitions

  • the invention relates to a spreading vehicle for solid, granular and liquid thawing materials, which are removed from separate containers and are each supplied in throwing rotors, which are adjustable in terms of driving speed and can be set to selectable scattering densities.
  • the liquid thawing substances are not scattered separately, but are only used for moistening the solid thawing substances (e.g. DE-PS 1 936 564, DE-OS 1 534296, DE -OS 1 459 760, DE-AS 1 299 013, CH-PS 516 050).
  • DL-PS 70 612 Devices for spraying a de-icing salt solution on traffic areas are also known (DL-PS 70 612), in which a spray device with spray nozzles is mounted on a vehicle, which is supplied with the de-icing salt solution from a liquid container carried by a liquid pump, in which the de-icing salt solution is in controllable quantities depending on the driving speed is delivered to the spraying device.
  • DL-PS 70 612 Devices for spraying a de-icing salt solution on traffic areas are also known (DL-PS 70 612), in which a spray device with spray nozzles is mounted on a vehicle, which is supplied with the de-icing salt solution from a liquid container carried by a liquid pump, in which the de-icing salt solution is in controllable quantities depending on the driving speed is delivered to the spraying device.
  • Spreading devices are already known (DE-PS 2011 894) which can be placed on the loading ratchet of a vehicle and with which different spreading materials, e.g. B. grit and salt can be spread simultaneously or separately and have two separate containers, each with an endless conveyor and a spreading plate.
  • these spreaders have a control device for the driving speed-dependent drive of the endless conveyors and for setting different constant drive speeds of the spreading discs, wherein the drives of the endless conveyors and the spreading discs of both containers can be switched on both individually and together.
  • the two containers and their endless conveyors are arranged parallel to one another in the direction of the longitudinal axis of the vehicle and each equipped with a spreading disc at the rear end of the endless conveyor, at least one of which can be pivoted about an eccentric vertical axis and can be locked in any pivot position.
  • double spreaders only solid granulated spreading materials can be spread.
  • both spreading devices are used at the same time, it is possible to achieve twice the spreading width of a single spreading device, so that even relatively wide streets can be spread over the entire area in one spreading process.
  • the maximum achievable spreading width is only about 10 mtr., Which is due in particular to the fact that the two spreading devices are arranged close to each other and only allow a spreading angle of maximum 90 ° if a homogeneous spreading density is to be ensured. Liquid thawing materials alone cannot be spread with these known spreading devices.
  • the invention has for its object to provide a spreading vehicle of the type mentioned, with the liquid or solid thawing agents either separately or mixed in one operation over a maximum spread of about 25 mtr. can also be spread in any narrow spreading width with a homogeneous spreading density and with which a fog-forming spray effect is largely avoided when liquid thawing materials are spread separately.
  • Such a gritting vehicle is particularly intended and suitable for combating winter slippery, namely both snow and ice slippery on airport runways.
  • a particular advantage can also be seen in the fact that the spreading of liquid thawing substances alone or by spreading a mixture of liquid and solid thawing substances can prevent the formation of smoothness. Due to the separate controllability of the hydraulic motors driving the individual endless conveyors and the hydraulic motors driving the individual liquid pumps, it is also possible to use the three spreading devices at the same time to spread different thawing materials, namely liquid or solid thawing materials, so that the spreading vehicle according to the invention is optimally suited to the given conditions can be used. This also includes the possibility of sprinkling narrow area strips by using only one or two spreading devices.

  • the throwing blades of both groups each consist of wall elements seated vertically on the top of the spreader plate, the upper sections of which are each bent over their entire length in the form of a circular arc in the direction of rotation. Throwing blades of this type ensure a flat throwing pattern and contribute to avoiding the atomization of the liquid thawing material.
