Description
Spreader for Winter Servis© Vehicles
The Invention relates to a spreader for winter service vehicles with which de-icing materials cars he distributed on road surfaces, as wail as components for the operation of such a spreader and a logistics mathod'for these components.
Winter service spreaders are known either as so -called attachment devices, which are mounted on loading beds of lorries, or as a fixed part of a winter service vehicle- •Until recently either dry salt or wet salt was spread In winter road clearance, in wet salt spreading the salt is wetted with liquid when It is spread, l.e. salt and lipoid are distributed jointly. The liquid is normally a salt sedation, so-called "brine*, which is mixed with the salt to be spread either on the distributing plate or on the path to the distributing piste.
In order to produce the brine fresh water Is often pumped through underground rock salt deposits In order to dissolve the salt in the water, There is however also brine that cars he obtained from natural sources, The brine is then transported either in tankers to commercial customers, or so-called saline salt or common salt is obtained by evaporating the brine, from which the customers then regenerate brine. Saline salt: can however also be obtained by evaporating sea water end used for the production of the brine required for the winter service applications:
The brine is contained on the spreader In an extra tank, which for example is mounted on the side of the spreading material container in which the gritting salt is stored.. A. normal spreader with a capacity of 5 cm gritting salt has such ms extra tank with a tank volume of for example 2260 I.
Recently Instead of dry salt and wet salt spreading often pure brine is "spread*, l.e. Sprayed On the road surface. In order to spray a standard spreading distance of ca, SO km with pure brine, a tank volume of ca. 8ÖQÖ· I is required. The extra volume must therefore be provided by a brine tank with a volume of ca. S7ÖÖ1, For this purpose cascade tanks are used, be. for example four conventional brine tanks ere coupled to one another in a, cascade arrangement.
On recount of the available struckrai length of the terries that can be used for winter reed etesrahoe fho desired volwne cannot always be achieved. The centre of gravity of such a construction with for example three extra tanks means that le certain circumstances either the front sale or the rear axle is overloaded.
The object of the present invention Is therefore to provide aspreader 1er winter service vehicles and a winter service vehicle equipped with such a spread*sr that is suitable both for' dry salt spreading and brine spreading and preferably also for wet salt spreading; without however the aforementioned weight distribution problems.
This object is achieved by a spreader with the features of the independent claim 3.. Advantageous arrangements and developments of the Invention ere disclosed in the dependent claims. Subordinate claims relate to correspondingly adapted components for a spreader according to the invention.
Accordingly a spreader according to the invention for winter service vehicles Includes in a conventional way a spreading material container for containing solid de-icing materials to he spread and a spreading device, in particular a rotating distributing plate., that can be functionally coupled to the spreading material container, for spreading the solid de-icing materials contained: In the spreading material container when the winter service vehicle is on the road. A spraying device for spraying liquid de-icing materials in pure form is also Included According to the Invention the brine tank that can be functionally coupled to the spraying device is however now formed by the spreading material container Itself. Accordingly the spreading material container is arranged so that Instead of just being used as a spreading malehal cemaine? it can also he used as a brine tank, and the spreader is correspondingly arranged so that liquid de-icing materials held in the spreading material container can he fed to the spraying device.
The weight distribution problems described in flse Introduction do hot occur in the spreader according to the'Invention. Irrespective of whether the spreader Is used for Spreading dry sait or for spreading or spraying a pure salt solution, the centre of gravity of the solid and liquid de-icing materials to be spread is always located te a central position of the spreading material container and therefore on or as a rem in frontot the rear axle of th© vehicle. Exoomlv© ©xtra tanks. In partlsniareasesde tanks, can therefore de dispensed with.
However, an extra tank or several extra tanks can be .provided as betöre in a conventional Way for holding liquid, In particular brine, for wet salt spreading. Accordingly the extra tank Is coupled or can be coupled functionally to the spreading device In order to supply the spreading device with at the same firne liquid from the extra tank in addition to solid de-icing materials from the spreading material: container. The extra tank can however, as Is already the case in the prior art, also be additionally connected to the spraying device for the purpose of pure brine spreading.
In this way a §pr©ador Is created that combines the three different conventional spreading methods, namely dry salt spreading, wet salt spreading and pure brine spreading. Preferably the spreader is then designed so that In the case of pure brine spreading brine from the spreading material container as well as brine from the extra tank can he sprayed.
Eh 579 3:1:1 A describes a spreader according to the pre-charaeferlsing part of claim 3,
According to the 'invention the brine contained in the spreading material container' is not fed directly to the spraying device but te an extra tank, which in turn is coupled or can he coupled to the spraying device. Such extra tanks are nowadays already a normal part of a winter service spreader, as was already explained in the introduction. Their normal function consisted in the past of mixing, for the purposes of wet salt spreading, brine with the gritting salt supplied from the spreading material container. The extra tank or tanks are however nowadays alternatively used for pure brine spreading:.
The advantage of supplying the brine contained In the spreading material container not direct iy to the spraying device but In step drilling the extra tanks that as a role are already present, is that already existing spreaders can be upgraded without any problem, in particular these extra tanks already have an optimally designed pumping system for conveying brine. The principle of refilling or topping up the extra tank or tanks with the brine held in the spreading material container can be applied in the case where the brine is stored in a separate liquid tank inserted into the spreading material container, and also, in the case where the brine is stored "iPose" in the suitably sealed soreading material container. In both cases the brine can be transferred: from the spreading material container and/or the liquid tank housed therein into the extra tank dr tanks coupled to the spraying device, for example by means of a feed pump, for example e submersible pump, and a corresponding -conveying hose,
The system is preferably arranged so that the aforementioned pump Is activated if a predetermined liquid level in an extra tank is not reached. This can easily be realised by means of a float gauge in the extra tank and a controller connected to the float gauge and to the pump. Other control systems are also conceivable.
Instead of the use of a pump it Is also conceivable to pressurise the liquid volume and then simply open an excess pressure value if brine is to be transferred to the extra tank. For this purpose the liquid tank housed In the spreading material container can for example be formed like a hag and weighed down from above with an appropriate weight.
The spreader can according to an alternative embodiment not according to the Invention be arranged so that either the spreading device or the spraying device can be functionally coupled as desired to the spreading material container, depending on which functionality is specifically required. In particular it may be convenient for this purpose to extract the gritting salt and the brine from the spreading material container via the same transport path..
In order in fois case to he able to serve as a brine tank;, the spreading material container must be formed suitably I leged-tight. in this connection the conveying device vis which: the solid de-icing materials are normally supplied from the spreading materiel container to the spreading device can he a problem. Normally a conveyer belt or one or more screw conveyors are used as conveying devices. These convey the solid de-icing materials from: the spreading material container normally to a downpipe or a chute of the spreading device, through which the de -icing materials are then fed under the force of gravity for example to a rotating distributing plate.
In connection with the present Invention it is advantageous td use as conveying device not a conveyor belt but instead one or more screw conveyors, 'These can as a whole be manufactured·from a corrosion-resistant materia! that withstands the aggressiveness of the solution, end the screw conveyor hearings can also be made water-tight without major technical effort end expenditure. in pria ci pie it is of course conceivable to seal the spreading material container reliably with respect to the conveying device, whether the latter is a conveyor belt or a screw conveyor, If the spreading material container is to bo converted to a brine tank, for example by means of a sealing plate Over the conveying device, so that the brine would have to be extracted from the spreading material container via another, separate transport path than that used for the gritting salt. For a simple conversion process it is however less complicated and therefore preferred if the Interface that serves for the conversion of the spreading material container to a brine tank is arranged in the transport path to the spreading device and :$ preferably subordinate to the conveying device. Accordingly an Interface --- preferably subordinate to the conveying device ™ between the spreading material container arid the spreading device is adapted so fisat It can optionally also be used as an interface between the spreading material container and the spraying device, namely if the spreading material container is to be used as brine tank. Ideally this Interface lies In the region of the downpipe for chute) loading to the-distribution plate, In particular preferably at the upper end of the downpipe, ie. preferably directly at the outlet end of the conveying device.
In this connect ion it is advantageous to design the spreading device so It eon be displaced or swivelled, so that by displacing orswiveiling at least part of the spreading device the Interface can be released for use as an interface between the spraying device and the spreading material container. With such a construction the spreader can he converted quickly and easily between the dry salt spreading and wet salt spreading modes and pure brine spreading.
The conversion from dry salt spreading to pure brine spreading is accomplished by connecting a liquid line leading to the spraying device, to the released interface via an associated attachment, pipe, Also the suction pipe is advantageously Installed in a displaceable or swiveiabie manner, so it can be moved quickly and easily into its position attached to the interface, For this, the interface er the sealing surface of the suction pipe cooperating wish the latter has a Seal that can withstand the hydrostatic pressure of the spreading material container when completely filled with brine,
Conventional spreading· material cöntaíners íve filled from above and ara accordingly open at the top. The opening surface is normally significantly larger than other horixontal cross-sections through the spreading materiel container. This is because on the one hand the gritting sait should be fed under the force of gravity to the centrally arranged spreading material conveyor at the lowermost level, i On the other hand the targe filling opening facilitates the rapid filling through a protective grating. Owing to the filling of the spreading material container through the protective grating agglomerations of spreading material are broken up. Also, the spreader accomllng to the Invention is advantageously equipped with stich .a protective grating. in the case of pure brine.spreading the protective grating is replaced by a removable cover, with which the upper opening of the spreading material container can be completely covered, so that during travel no liquid can spill over from the spreading material container. Such a cover can he provided with suitable seals and can preferably be fastened to the spreading material container with quick-release fasteners. it is particularly preferred if the cover has splash guard wails that protrude from the cover and extend into the spreading material container. In this way sudden weight displacements of the brine in the spreading material container, for example during braking, acceleration, rapid turning and sharply cambered road surfaces., are prevented. Accordingly if is advantageous to provide the splash guard wails both in the longitudinal direction and the transverse direction (referred to the predetermined travel direction of the spreader).
According to a further embodiment, not in accordance with the invention., the gritting salt and the brine are not removed from the spreading matériái container via the same transport path, instead, in addition to the outlet opening for the spreading material a Separate liquid outlet opening Is provided, through which the brine contained In the spreading material container can be fed to the spraying device via a separate transport path when the spreading material container is used as brine tank.
This embodiment offers the advantage that an interface between the spreading device .and the soroadine material container, which could oossibiv he used: as an .interface between the spraying device, and the .spreading materiel container, Is net necessary. The structural expenditure associated with this can thus he avoided, instead, it simply has to h® ensured that the brine contained in the spreading materia! container does net flow out through the spreading device. This cats be achieved in many ways. For example, in a simple way a sealing plate can he inserted lote the spreading material container over the spreading materia; conveying device.:
However, Instead of this a separate liquid tank can advantageously he housed or Inserted into the spreading material container. This liquid tank has a liquid connection with which the liquid tank can he coupled to the aforementioned liquid outlet opening of the spreading material container, the term "coupling" should be understood broadly in this connection and includes the case In which the liquid connection ot the liquid tank is simply led outwardly through the liquid outlet opening, or conversely for example a hose connection leading through the liquid outlet opening of the spreading material1 container Is attached to the liquid connection of the liquid tank housed In the spreading material container. In order to prevent gritting salt passing through the liquid outlet opening of the spreading material container when the spreading material container is not used as a brine tank, the liquid outlet opening can ho closed from the Inside or outside, for example by means of a simple flap or a simple slider, which preferably can be actuated from outside the spreading materia; container.
The use of the aforementioned liquid tanks that contain the brine and ore housed in the spreading material container, offers apart from the fact that additional seals do nor have to be provided on the spreading device, the particular further advantage that the leading of the spreading material vehicle can be accomplished very quickly by replacing an empty liquid tank by a full liquid tank. For this purpose the liquid tank to be housed in a spreading materia; containerls preferably suitably adapted, In particular as regards its dimensions. Thus, the liquid tank should have a substantially triangular, trapeaoidal or generally funnel-shaped vertical cross-section so that It can be housed 1rs conventional spreading material containers with optimal utilisation of the space. Such a liquid tank can comprise several separate chambers or preferably chambers connected to one another.
It is however also possible to use severe! of these liquid tanks in series In the spreading material container.
For the optimal handling of the liquid tanks these preferably have transporting elements for lifting the liquid tsniu Preferably the transporting elements are designed In order to transport the liquid tanks by means of a forklift track, The transporting elements accordingly have the tine spacing of conventional forklift tracks, in this connection it is particularly advantageous to attach the transporting elements to an upper side of the liquid tank, so that the liquid tank can easily be lowered from above into the spreading materiel container, instead of a forklift truck a crane can of course also he used. For this, it is convenient to provide a centrally arranged transporting element, for example an eye for the crane hook, on the upper side of the liquid tank.
Such liquidtanks can easily be stored, for example in shelf warehouses, and can be removed from storage as required to replace an empty liquid tank.
Overall an optimised logistics process is provided In this way for the transportation of liquid de-icing materials (brine) for winter service use. To this end a number of liquid tanks ore filled with liquid de-icing materials at a da-icing matériái supplier, for example directly at a saltworks, and delivered to a debcingsoateds! customer, for example to an authority responsible for wirster road clearence, The liquid tanks remain With the customer until the liquid de-icing materials are consumed, and are then returned to the di-icing materials supplier, The essential feature In this logistics process is that the liquid tanks provided by the de-icing materials supplier not only remain with the consumer, but in addition during winter service use are carried on a winter service vehicle of the customer.
It is particularly advantageous if the liquid tanks are substantially formed by a flexible shell or envelope. The Inner volume? of the shell decreases to almost sera when the liquid tanks are empty. Conversely, the volume of the liquid tanks increases when the shell ?s filled with liquid -de-icing material. This has the advantage thatthe spasm needed to store trre empty kqwd tanks is minimised end also the transportation of the »empty liquid tanks back to the de-iemgmaterials supplier Is less complicated,
The invention is illustrated hereinafter with tire aid of a preferred embodiment and with reference to the accompanying drawings, in which:

Fig. ô shows a spreader according to a fourth exemplary embodiment, according to the invention, and
Fig. 7 -shows a spreader according to a fifth exemplary enrbodlment, according to the invention,
In fig. 1 a top-mounted spreader 1 is illustrated as a structure on a loading surface of a lorry, 4 spreading material container % which has a funnel-shaped cross-section, is mounted on a welded carrier frame 2, sothst de-icing msterlais contained in the spreading materials container coiled: at the conically tapering base of the spreading material container 3. 4 screw conveyor on the base of the spreading materia! container transports solid de-icing materials, in particular gritting salt, from the spreading material container 3 to an outlet 4, through which the de-icing materials can then fail under the force of gravity into the tíöwopipe S of a spreading device 6 and through the downpipe 5 onto a distributing plate 7 of the spreading device 6. in the representation illustrated in Fig, 1 the spreading device 6 is however illustrated swivelled out about a rotation agis 8 from an “Interface" 9. The Interface 9 Is formed as a flange, to which the spreading device § can be coupled whan the sproader 1 fs to he employed for spreading solid de-icing materials using the spreading device là- as is illustrated In fig, 2, Two extra tanks TO for liquid, In particular for a salt solution, are provided in order to mix the dry de-icing materials falling through the downplpe S with: a suitably motored amount of lipoid for this case, This procedure takes place In a manner known per so via a suction line 15,2 Using a suitably controlled pump 18. The mixing site need does not nave to he he in the downplpe itself, hut the mixing can ~ differently to the case shown in Fig, 2 ~ teke piece for example also only at the lower end of the downplpe 5 on the distributing plate 2.
Further extra tanks XC) can he provided for example In front of the spreading material container 3, In particular the extra tanks 10 can ho designed significantly smaller in favour of an enlargement of the content of the spreading material container 3, as is illustrated in Fig, 1. If several extra tanks 10 are provided for mixing liquid de-icing materials, then these are connected to one another via lines,
Tho spreading device 6 can he stopped In any unfolded position and arranged so that in the unfolded state It occupies as little additional space as possible behind the spreader i. With the unfolded spreading device 6 the spreader 1 can he used to "spread” or spray pure brine. For this. Ipate^d Of the Spreading device 6 the attachment pipe 14 of a suction line 19,1 is coupled to the flange or the ''''interface" $, and tho spreading material container 13 is used to hold liquid de-icing materials., in particular pure brine. By means of a suitably controlled pump fh uhe brine can then be fed;from the spreading .material container 3 through the suction line 15.1 to a spraying device 17 - shown purely schematically in Fig, 1 - end In this way distributed on road surfaces.
In the same way as the spreading device 0 eon be swivelled out about a rotation axis 5 from the interface 9.. -also the attachment pipe 14 of the suction line 15 can be swivelled about a rotation axis X8, Instead of swivelling out tho whole spreading device 6 - or optionally also only displacing it-- also only part of the spreading device 5, for example a section of the downplpe $, can he swivelled out or displaced. Also, the attachment pipe 14 can he designed to be disniaceable instead of swivellabie.
The attachment pipe 14 seals the interface 4 in a liquid-hght manner and has for this purpose corresponding sealing eiepmhts, for example an O-rlng seal, which can Withstand the hydrostatic pressure befit up by the brine in the spreeding matériái container 3. Also the hearings of the (net illustrated} screw conveyor on the base of the spreading material container 3 should: be suitably protected by means of suitable seals, for example Up seals, against the Inflow of the aggressive salt solution.
The function of pure brins spreading, as illustrated 1rs Fig, 1, and· purs 'dry salt or wet salt spreading, as illustrated in fig, 2, can be achieved with a single pump 16 and suitable valves 11, % and 11.2, By means of the valve 11,1 formed as a three-way valve 11,2 (e.g, ball valve) the spreading materiel container 3 used as brine tank and the extra containers 10 can be connected on the suction side to the pump IS for the pure brine spreading.
The valve 11.2 ;e,g, half volve)., also formed as a three-way valve and controlled by the puntp lb. Is for this case adjusted so that it connects the pump 16 to the spraying device 17. The valves can ho adjusted either manually or automatically In a controlled manner with an electric motor with the aid of a proximity switch on the attachment pipe 14.
The three-way valve 11.1 has a T-branchlng and the three-way valve IL2 has an t-branching, se that by suitable valve adjustment as Illustrated in Fig, 2, a changeover can he shade from pure brine spreading to purs wet salt spreading. For this purpose the three-way valve 11,1 with T-branching simply also connects the two extra tanks 16 on the suction side to tile pump fű and the three-way valve 11.2 with L-branchlng connects the pomp 16 to the spreading device 8. if dry salt Is to be spread, l.e, without mixing with brine from the extra tanks 10, either the pump 16 can he switched off or, preferably, in addition the three-way vaive 11,2 is turned so that the line path from the pump 16 to the spraying device 17 aryl aises to the spreading device 6 is interrupted.
On the other hand It is also possible to bring the ihre«nw«ty valve 11,2 from the position illustrated In Fig. 2 info a,position la which it connects the pump 16 to the spraying device 17. Than dry salt can he spread by means of the spreading device 6 and also pure brine can be spread by means of the spraying device 17, A wet salt spreading via the spreading dévies d. èe. with simultaneous addition of brine from the extra tanks 10, and;the distribution of pure brine via tbs spraying device 17. is not possible With the arrangement Illustrated in Figs. 1 and 7. However, within the scope of the invention it is also possible to ensure this functionality by suitably modifying the system, for example by other or additional directional: valves and/or additional lines and/or line branchings and/or by one or mom further' pumps. in order to fill dry de-icing materials in the spreading materia; container 3 a protective grating 17 is provided, which can be placed on supporting elements 13 of the spreading material container 3. This is illustrated in Fig. 3. The titling of the spreading material container 3 then takes place through the protective grating 3.2, so that lumps of spreading material are broken up when passing through the protective grating 32. in the case where the spreader is used to spread pore brine the protective grating 12 can he removed from the spreading material container 3 and replaced by a cover 19. in order to prevent the brine spilling over morn the spreading material container during travel. The cover :1.9 is securely fixed to the spreading material container :3 by quick-release closures 29. The pulck-roiease closures 20 are here formed as levers end have latch elements that can be brought into a locked engagement position with the spreading material container by turning the levers.
As a variant from the purely basic representation eccordingtO Fig. 1 the cover 19 can also be placed in a sealing manner on the outer wails of the spreading material container or can be reliably sealed in another way with respect to the wall of the spreading material container 3. so that neither can brine escape from the spreading material container 3 nor can dirt nr rain enter the spreading material container a. in this case a ventilation opening 21 is provided on the cover 19. the cover 19 Is provided on Its lower side with securely welded metal sheets in the longitudinal direction 22 and transverse direction 23. These metal sheets act as splashguard walls and prevent sudden changes in the weight distribution of the brine In the spreading material container In the event of sudden accelerations. fig, 4 shows a second e^mpisry embodiment, which: ess&fttläfly differs; from the first exemplary embodiment in that the gritting salt and the brine are oof removed from the spreading material container 3 vis the same transport path, instead, to remove the brine a separate liquid outlet opening 30 1s provided, to which the suction line 15,1 is attached. A sealing plate .3.1 Is inserted into the spreading material container 3 above the foot illustrated) spreading material conveying device, whether it is a: screw conveyor device or a conveyer Pelt, By means of sealing lips on the circumference ef the sealing plate 31 It Is ensured that the brine cannot otherwise lead from the spreading materia! container and In particular cannot escape via the spreading device b, A sealing effect is ensured by the weight of the brine on the seeling plate 31, An additional dampiogby means of damping levers or other means |not Illustrated) can enhance the sealing action,
Hg, 5 shews a third exemplary embodiment, which essentially differs from the second exemplary embodiment according to fig, 4 in that the brine Is not contained directly in the spreading material container 3, but instead a liquid tank 40 is housed in the spreading material container 3 In order to hold the brine, The liquid tank 40 cars be filled with brine via a filling pipe 43.
Handles 41 for transportation are provided on the upper side ef the liquid tank In a spacing matching the tine spacing of forklift truck forks, A further handle is centrally provided In order tes transport the liquid container 40 if necessary with a single crane book.
The liquid container 40 has a liquid attachment (here not visible}, which cooperates with the liquid outlet opening 30. For example, this could1 be a simple>to~use bayonet connection, ideally the liquid outlet opening 30 cooperates with the liquid attachment of the liquid container 40 however so that the suction line 1S.1 can be attached via the liquid outlet opening 30 to the liquid attachment of the liquid tank. 40. The liquid tank 40 can then be insetted from above into the spreading material container 3 and afterwards the suction line 13.1 can be attached through the liquid outlet opening 30 of the spr eading material container 3 to the liquid attachment of the liquid tank 40, for example by means of a quickveiease connector. figs, 6 and 7 show respectively a fourth and fifth exemplar -embodiment, which essemialiy differs from the second and third exemplary embodiments in that the brine held in the spreading materia! container 3 is not fed: directly to the spraying device 17 Put first of all to an extra tank Id. for this, a suction pump SI in staked over a fifing pipe of the extra tank 1Ô pumps out through a hose SO dipping into the spreading material container 3 the brine contamed therein and discharges it into the extra tank Id, instead of the suction pump 51 an immersion pump can also he provided at the correspondingly other end of the hose SO. The fii ling state of the extra tank id is monitored by means of a float gauge 52 arranged: in the extra tank id. As soon as the filling state fails below a predetermined level this is signalled by the float gauge 52 to a control device C, which then brings the pump 51 into operation. The respectiveswltched-on duration of the Pump SI can he deteonlned in many different ways, for example depending on the output of the pomp over a predetermined time period, or can be terminated when an upper liquid toveí In the extra tank Id detectable by the float gauge 52 is reached. Instead of fne electronic control C a purely mechanical way of activating and deactivating the pump 51 ton also be realised., for example if the float gauge 52 Is formed as a part of the pump SI and projects through the filling pipe of the extra tank 10 Into the extra tank 10-
The fifth exemplary embodiment according to Fig, 7 differs from the fourth exemplary embodiment according to fig, 6 again simply in the fact that the brine Is not directly contained in the spreading material container %. but Instead a liquid tank 40 Is inserted Into the spreading material container s in order to contain the brine. Accordingly the hose 50 is attached to the filling pipe 42 of the liquid tank 40, and a hose extension 50a extends from the filling pipe 42 Into the liquid tank 40. Alternatively it is possible to form the hose SO and: the hose extension 50a as one piece and to guide it through the filling pipe 42 to the floor of the filling tank 40, preferred exemplary embodiments, not according to the Invention, are described In the following paragraphs, though the invention Is however defined In the claims.
