Definitions
- the invention relates to a winter service spreader for spreading granulated grit such as salts, grit, sand and the like and in particular the invention relates to a spreading disc for a Winter gritting equipment.
- Known spreading devices have spreading plates, which are essentially one vertical axis of rotation are driven in rotation and on their top have upright, radially extending wings.
- the wings By means of the wings is the spreading material, which the spreading disc through an outflow opening is fed from above, accelerated in the circumferential direction and due to the centrifugal force thrown radially from the spreading disc.
- the throw range and accordingly the spread on the road can be achieved by varying the speed of the spreading disc individually to the desired one Dimension can be set.
- the wings on to form the spreader plate of different lengths the radially inside lying ends (roots) of the wings on a common radius and the radially outer ends lie on different radii and the spreading plate edge is flush with the wing ends.
- the spreading material is different depending on the wing length Radially accelerated speeds and in the form of a grit fan accordingly close or far around the spreading disc.
- the discharge angle differs depending on the wing length, because the spreading material leaves the spreading disc earlier for the short wings than for the long wings. Overall, this results depending on the wing length Spreading compartments that differ in terms of throwing distance and throwing angle and which overlap in such a way that a uniform spreading density is achieved over the entire spread.
- a disadvantage of all previously known spreading devices is that individually adapted spreading discs are required for certain spreading width ranges. So far it has not been possible to develop a spreader that achieves variable spreading widths between 2 and 12 meters with a single spreading disc, a uniform spreading carpet over the entire spreading quantity range from 5 to 40 g / m 2 and vehicle speed range from 3 to 80 km / h achieved over the entire spreading width and only required one spreading disc size. So far, at least two different spreading disc sizes have been required, for example a spreading disc for the 2 to 8 meter spreading range and a second spreading disc for the 8 to 12 meter spreading range.
- the invention is therefore based on the object of proposing measures that allow a winter service spreader with only one to be able to use a single spreading disc for large spreading ranges and an even spreading carpet across the entire width produce.
- This object is achieved in that the differences in length or at least the differences in the outer wing radii of the wing arranged on the top of the spreader plate are chosen extremely large. Due to this simple constructive measure of the different wing lengths, which was originally proposed to a lesser extent to achieve a more uniform distribution of the spreading material over the spreading width (DE 40 39 795 C1), a spreading carpet can be variably adjusted in a large spreading width range with a single spreading disc, the unexpected In this way, both with small and large spreading quantities (5 to 40 g / m 2 ) and at low and high driving speeds (3 to 80 km / h), a good and at least acceptable spreading material distribution over the entire spreading width is achieved.
- the solution according to the invention has the advantage that the spreading width can be adjusted in a conventional manner by varying the speed of rotation of the turntable.
- the spreading plates known so far were different, despite their Wing lengths essentially circular. Because to achieve one it is sufficient to distribute the spreading material uniformly if the Ends of the long wings lie on a radius that is in proportion to the radius on which the outer ends of the short wings are about 1.06. That means the radius difference is included only 6%. In contrast, the difference in radii of the invention Scatter plates at 20% or more, preferably at about 40%. As a result, the spreading plate according to the invention is no longer almost round, it's more like a star shape. This is especially true if the maximum wing length is 250 mm and on a radius of 360 mm ends and the minimum wing length is about 150 mm and up ends with a radius of about 260 mm. Spreading widths between 2 m and 12 m and with an essentially even distribution of spreading material can be set variably with such a spreading disc.
- the wing lengths of such wings which are between a longest and one shortest wings are preferably graded evenly to achieve an even distribution of grit.
- At least three groups consist of at least three wings of different lengths are required, to achieve a good distribution of the spreading material over the entire width. Particularly good results were achieved with a spreading disc on which four wing groups were arranged, each consisting of three wings consistently graduated wing lengths, i.e. whose outer wing radii were evenly graded.
- the spreading material distribution can also be improved. These breakthroughs have only at low rotational speeds, i.e. with narrow spreading carpets, an effect on the distribution of the grit, since the grit Breakthrough areas do not even cover at high speeds.
- the openings should preferably be in the direction of rotation before longest wings can be provided. Breakthroughs on the Radius of 190 mm and start both radially and tangentially extend around 90 mm, have proven to be suitable.
- a uniform spreading material distribution up to the edge of the road be positively influenced by the wings on their radial inner ends different heights above the surface of the spreader plate, the so-called root height, preferably the short wings have a higher root height than the long wings. This ensures that the short wings take more grit with them, which is thrown earlier than that of because of the shorter wing length grit taken along the long wings, creating more grit is carried out to the edge of the road.
- Fig. 1 is a spreading plate 1 according to a preferred embodiment the invention is shown schematically in plan view.
- the spreading disc 1 carries four groups of three different on its top long wings 2, 3, 4.
- the wings of the same length are in Distributed circumferentially evenly and regularly to the other wings spaced.
- the spreading disc is 1 attached to a substantially vertical shaft 6 by means of a hub 5, which can be driven to rotate about an axis of rotation 7.
- Axial to Axis of rotation 7 is a truncated cone on the top of the spreader plate 8 arranged, which on its outer surface with 24 sawtooth-like Teeth 9 is provided.
- the Spreading plate 1 on a flat circular section 10.
- the radius of the Circle section 10 and the lower radius of the toothed cone 8 correspond about a third of the maximum radius R2 of the spreading disc 1, for example 110 mm with a spreading disc radius R2 of 360 mm.
- the radially outside between the tooth cone 8 and the outer edge 11 lying ring zone of the spreading plate 1 is concave and points to the horizontal plane 12, in which the circular section 10 of the spreading plate 1 lies, a cone angle ⁇ of about 5 ° to 10 °, in particular 9 °, so that the outer edge 11 of the spreading plate 1 in the vertical direction above the Circle section 10 lies.
- a liquid container coaxial to the axis of rotation 7 13 fixedly arranged, which with a liquid supply device 14 is provided, through which the so-called brine, typically Calcium or sodium chloride for moistening the salt granulate the spreading plate 1 is supplied.
- brine typically Calcium or sodium chloride for moistening the salt granulate the spreading plate 1 is supplied.
- a filling support 15 is arranged, via which the liquid container 13 is filled with brine.
- the salt granulate is through a discharge opening, not shown diagonally on top of the tooth cone 8 in the area of the liquid supply device 14 abandoned so that it is due to the rotation of the tooth cone 8 is thrown radially away in the moistened state.
- the tooth cone 8 is therefore also referred to as a centrifugal wheel.
- the salt granules are thrown away by the wings 2, 3, 4, which with their radially inner ends 2a, 3a, 4a each without gaps to one the tooth flanks 9 of the tooth cone 8, in the circumferential direction 17 taken.
- the tooth flanks 9 of the tooth cone 8 form with the Wings 2, 3, 4 form a closed radial guide surface for the spreading material. Because of the rotation of the spreading disc 1 in the circumferential direction 17 is applied to the spreading peripheral speed Spreading material accelerated in the radial direction (centrifugal acceleration) and slides along the guide surface 20.
- wings 2, 3, 4 Only on the radially outer ones Ends 2b, 3b, 4b of the wings 2, 3, 4 leave the spreading material the wings with a discharge speed that essentially depends on the rotational speed of the turntable 1 and the outer wing radius R2, R3, R4 the wing 2, 3, 4 depends.
- the upper edges of wings 2, 3, 4 are in Circumferential direction bent like a blade to prevent that Granules evade upwards.
- Fig. 1 shows clear differences in length of the wings 2, 3, 4, the longest wings 2 are 250 mm long, the medium-long wings 3 are 200 mm long and the shortest wings 4 are 150 mm long.
- the wings are thus evenly graded in length to ensure even distribution of spreading material to reach over the spread.
- the outer edge 11 of the spreading plate 1 closes with the outer ones Ends 2b, 3b, 4b of the individual wings 2, 3, 4 are flush. This gives the turntable 1 in plan view a star-like shape.
- the outer edge 11 there is no need for a linear connection between the external ones Form wing ends 2b, 3b, 4b.
- Other contours can affect the spreading material distribution have a positive impact.
- a breakthrough is in each case in the direction of rotation 17 in front of the longest wings 2 19 provided in the turntable 1.
- This breakthrough can be closed be designed as a flap 18 (Fig. 2).
- the breakthroughs 19 have the function at low rotation speeds and thus at small spreading widths part of that covered by the long wings 2 Branching off spreading material and thus the area of the spreading area near the turntable to sprinkle.
- the spreading material slides at higher speeds not at all on the surface of the turntable 1, so that it too cannot trickle through the openings 19.
- the trajectory of the grit thrown from the tooth cone 8 is for high speeds in Fig. 1 by the hatched area 16 approximately shown.
- the breakthroughs 19 shown in Fig. 1 begin approximately on a radius of 190 mm and have a radial extent of approximately 90 mm and a circumferential extent also of approximately 90 mm.
- Fig. 2 it can also be seen that the wings 2, 3, 4 depend of the wing length a different height at their radially inner Have ends 2a, 3a, 4a.
- This is the so-called root height.
- the wing height increases linearly and for all wings at the same angle and then run parallel to the horizontal plane 12, so that the wing height for all wings on the radially outer Wing end 2b, 3b, 4b is identical in each case and shown in the Embodiment is 40 mm.
- the different wing height profiles are shown in dashed lines in Fig. 2 for the wings 3 and 4.
- the purpose of the different root heights is with to distribute more spreading material to the short wings.
