Definitions

  • the present invention relates to a winter service spreader for a road service vehicle, comprising a spreading material storage container, at least one rotatingly driven spreading plate equipped with throwing blades on its upper side and having spreading material distribution unit, which has the at least one spreading plate on its upper side from the Litter material storage container charged with removed litter.
  • the present invention is aimed at making a contribution to solving this problem.
  • the above-mentioned object is achieved in a surprisingly simple manner in that, as stated in claim 1, in a winter service spreader of the type specified at the beginning, the spreader plate is characterized by a plurality of positively synergetically interacting features in their specific combination by having a central mixing projection protruding upwards from the spreading plate on its upper side, between the mixing projection and the throwing blades there is an annular zone free of throwing blades and the spreading plate at least in an outer ring zone which extends over 60% to 70% of the radius of the spreading plate , has a radially outward downward gradient between 1 ° and 12 °, preferably between 3 ° and 8 °.
  • the design of the spreading plate according to the invention makes it possible to achieve a very high spreading pattern quality even with comparatively small spreading widths, without the quality of the spreading pattern being impaired as a result.
  • the working area of a winter road spreader (also) designed to sprinkle wide traffic routes can be extended substantially downwards, ie into the area of narrow traffic routes. This results in a winter service spreader with a previously unknown flexibility of use while at the same time providing a high quality spreading pattern over the entire area of use.
  • a possible explanation for the wide range of possible uses of the winter service spreader according to the invention could be that, due to the specific design of the spreading plate, two different phenomena can be used to a greater or lesser extent depending on the speed when spreading the spreading material .
  • the spreading material is primarily ejected or thrown with a considerable (throwning) effect of the throwing vanes; This applies to the operation of the spreader according to the invention intended for the spreading of wide traffic routes, whereby values of about 500 / min to 600 / min, possibly also 650 / min, are to be regarded as typical maximum speed of normally dimensioned spreading discs.
  • the spreading material is distributed by a type of "trickling" that is more relevant, in which the spreading material under the action of gravity is inclined downwards to a greater extent than in the case of high speeds Surface of the spreading plate moves outwards and leaves the spreading plate (at a comparatively low speed) according to the inclination of the surface of the spreading plate.
  • the central (co-rotating) mixing projection protruding upwards from the top of the spreader plate is important, in particular in connection with the further characteristic feature that there is a gap between the central mixing projection and the throwing vanes, the throwing vanes each other In words, do not extend as far as the mixing projection, but end radially inward at a distance from this.
  • the spreading material is applied to the spreading plate, at least a substantial part of the spreading material hits the mixing projection;
  • the stream of scattering material is directed specifically against the mixing projection - by means of a corresponding configuration of the feeding unit that feeds it, which is matched to the scattering plate.
  • the mixing projection which can be designed in the form of a cylinder or truncated cone structured on its surface, provides an initial distribution of the spreading material on the spreading plate, which helps the formation of a very homogeneous spread pattern even and especially at very low speeds of the spreading plate.
  • the ring zone that surrounds the mixing projection and is free of throwing blades promotes the homogeneous distribution of the spreading material on the spreading disc, which further promotes a uniform spreading pattern, especially at low spreading disc speeds.
  • a second effect could also serve as an explanation for the fact that, when using the present invention, with a very good quality spread pattern, it is also possible to spread very narrow traffic routes. Because of the inclination of the spreading plate, the movement of the spreading material on the spreading plate from the center to the edge, based on the effect of centrifugal forces, is caused by gravity supported, which reduces the risk that - at low speeds of the spreading disc - spreading material remains on the spreading plate and / or adheres to it, is reduced. This enables a stable spreading operation, which is characterized by maintaining a movement pattern of the spreading material on the spreading plate within a narrow band, even at very low speeds.
  • the annular zone which has a downward gradient, is designed to be conical. In this way, the effects set out above can be achieved to a particularly pronounced extent.
  • the throwing vanes are preferably inclined forward in the direction of rotation of the spreading plate. Said inclination supports a concentration of the litter moving along the throwing shovels at the foot area of the respective throwing shovel in order to form a "scattering material jet".
  • the angle of incidence of the throwing blades with respect to the spreading plate surface is preferably between 60 ° and 90 °, in particular approximately 70 ° to 85 °.
  • Yet another preferred development of the invention is characterized in that the height of the throwing vanes decreases radially outward. This favors a concentration in terms of height of the spreading material thrown off in a fan-shaped manner by the spreading plate at high rotational speeds and, accordingly, a comparatively small fluctuation range.
  • the base line of the throwing vanes on the spreading disc increasingly lags against the direction of rotation as the distance from the center increases.
  • the deviation of the base line from a radial reference line is particularly preferably at least 10 °.
  • Such a pronounced inclination of the throwing vanes with respect to the direction of rotation or circumferential direction again proves to be favorable with regard to a homogeneous spread pattern with small spread widths.
  • the radially inner delimitation of the throwing vanes is at an increasing distance from the axis of rotation with increasing height. This applies in particular to the presence of a central distribution projection (see above). In this way, the litter that bounces on and off the distribution projection can be better "caught" by the throwing vanes and directed onto the surface of the spreading plate in order to be thrown off according to its inclination. This is also favorable for the development of the trickle effect explained above.
  • the spreader 1 shown in the drawing is suitable for being mounted on a conventional carrier vehicle. Since this is well known from the prior art, the carrier vehicle was not shown.
  • the spreader 1 also corresponds to the state of the art with regard to its basic structure, so that a detailed description is dispensed with and the latter (see, for example, FIG DE 10 2005 012 886 A1 ) can be referenced.
  • it comprises, in the usual way, a spreader frame 2, a spreading material storage container 3 supported thereon, a spreading material distribution unit 4 with a motorized spreading plate 5 which is driven to rotate about an essentially vertical axis X, and a feed unit 6.
  • the latter in turn comprises a chute 7, which feeds the litter to the spreading plate 5, which is drawn off from the litter reservoir 3 in a metered manner by means of a screw conveyor.
  • the spreading plate 5 is equipped with throwing blades 8 on its upper side O.
  • a frustoconical central mixing projection 9 (mixing cone 10), which is profiled on its circumference, projects upwards from the spreader plate 5 on its upper side O.
  • the spreading plate 5, ie its upwardly facing surface exposed to the spreading material applied, has an outer ring zone R with a downward gradient. This is conical (with an angle of inclination A of about 5 °) and extends, surrounding the mixing cone 10, over about 65% of the radius of the spreading plate 5.
  • the throwing vanes 8 are on the ring zone R, which has a downward gradient of the spreading plate 5, keeping a distance from the mixing cone 10. They are inclined forward in the direction of rotation B of the spreading plate 5, wherein in the foot region of the throwing blades 8, ie near the surface of the Spreading plate 5, the angle of attack C of the throwing blades 8 with respect to the spreading plate surface is about 80 °.
  • the throwing vanes 8 are bent forward in the direction of rotation B, so that the forward inclination of the throwing vanes 8 increases over their height. Since the distance between the relevant edge K and the spreading plate surface decreases with increasing distance from the spreading plate axis X, the height of the throwing vanes 8 also decreases radially outward. The radially inner delimitation 11 of the throwing blades 8 has an increasing distance from the axis of rotation X with increasing height.
  • the throwing vanes 8 are not oriented radially, but rather positioned in relation to the circumferential direction U in such a way that the base line 12 of the throwing vanes 8 on the surface of the spreading plate 5 increasingly lags against the direction of rotation B as the distance from the center increases.
