The removal and drop spreader device has at least one roller or shaft extending crossways through the container housing for loosening, conveying and/or removing spreadable material. A sling spreader unit (21) is also incorporated which spreads material over a less defined width and involves a plate distributor (2) fed with material preferably via a conveyor worm(3). The at least one roller or shaft is located on or in bearing components, which extend inwards from the wall (32) of the container housing.

Description

The invention relates to a spreader for mounting or attaching to vehicles, in particular for mounting on a loading platform that can be used as a storage container for grit a flatbed vehicle, with a container housing for receiving grit and a discharge and drop spreading device for discharging the spreading material from the container housing and for spreading the spreading material with a defined spreading width, the discharge and fall spreader at least one across the container housing extending roller or shaft for loosening, conveying and / or discharging the spreading material has and the spreader for receiving one either for spreading the fall spreading device wider but less defined spreading in width the centrifugal spreading unit that can be actuated from the container housing, some, preferably by means of a screw conveyor, with discharged Spreading material can be delivered to the plate spreader.

Such a spreader is for example from DE 35 02 569 A1, EP 0 651 096 A1 or US-A-4 588 113. These publications will be used for further disclosure Features of the spreader in question expressly referenced. Moreover is based on the disclosure of the unpublished European patent application 99 115 625.8-2303, to which reference is also hereby made in full is taken.

The invention particularly relates to a spreader for platform mounting, the Spreading device instead of the rear drop side on the loading platform of a truck, especially small trucks or a e.g. for use to keep clean Is usable multipurpose vehicle. The loading platform can Store grit; a filling of the spreading container or container housing or storage container of the spreader is then done by tilting the loading platform.

Winter maintenance is an important area of application for the spreaders of the type in question specifically where, among other things a defined spread is desired. To this Purpose of the known spreaders are the drop spreading device, for example is designed as a roller spreader. The option of these spreaders is particularly advantageous, to be able to carry out a broader spread using a plate spreader, whereby then the exact width of the spread pattern is not so precisely definable. This spin scatter is therefore in sensitive environments next to the area to be spread less suitable, so that in this case falling scatter should be preferred.

It is a concern of the invention, also in the case of drop scattering - roll scattering or trickle scattering - The greatest possible width, if possible the entire platform or vehicle width to be used as a spread. On the other hand, the width of the spreader should itself not or at most only slightly above the width of the platform and / or the vehicle lie.

This is achieved on the basis of a spreader of the type mentioned at the outset by that the at least one roller or shaft of the discharge and drop spreading device on or is stored in bearing elements, starting from the wall of the container housing extend inwards.

For the previously known spreading devices of the type in question, see the spreading device US-A-4 588 113, it is precisely such roller bearings or those which act on them Drive devices that spread over the spread and the container housing to the outside protrude. At worst, the vehicle could get caught on such protrusions, or the spreading device width must be correspondingly narrower than the vehicle width be carried out, which is also disadvantageous.

The person skilled in the art can only use the other publications mentioned schematically reproduced drawings do not have a special roller bearing remove.

Characterized in that according to the invention the roller bearings are arranged inside the container housing are, the container housing can be wider overall for a given spreading device maximum width be designed, which also benefits the internal volume.

Advantageous embodiments of the invention are the subject of the dependent claims. It but are all in the individual claims and in the description and drawings specified features, including specific individual features of the exemplary embodiment, in any combination with each other as well as viewed alone as interesting viewed.

The spreader is most preferred as a pure roller spreader - without a centrifugal spreader - or combined roller / plate spreader - with centrifugal spreader - educated. For this purpose, the discharge and drop spreading device forming the roll spreader a spreader roller. If this spreader roller is now equipped with bottom brackets, so that the effective width of the spreader roller extends at least partially over its bearing, so can - the wall thickness of the container housing and a possible narrower Chain drive for the spreader roller disregarded - almost over the entire width of the Spreading device a roll spreading.

In the case of roller spreaders known hitherto, when using moist fine-grained Spreading material - e.g. sand - observe an irregular spreading pattern. A significant one more even spreading pattern, even with such difficult to handle spreading material however, according to one aspect of the invention achieved by one for attacking the Spreading roller in the discharge and / or spreading section of the spreading and falling spreading device, especially in the area below the spreader roller, formed scraper for discharging and / or spreading wiping off what has stuck to the spreading roller Grit.

If the spreader is designed as a combined case / centrifugal spreader, it is preferred if the centrifugal spreader unit against one by the discharge and drop spreader and / or the main module of the spreader formed as a container housing Removable module with at least one that can be connected via separable supply lines own drive for conveying, loosening and / or spreading the spreading material moving parts is formed. By removing the spreader module a simple fall spreader, for example roller or trickle spreader, which is also known as such can be sold. By attaching the centrifugal litter module is the Fall spreader can be upgraded to a combination device.

In principle, the screw conveyor could already be on the discharge and drop spreader be provided. For the modular design, however, it is preferred if the centrifugal spreader unit a screw housing with the screw conveyor in it and the one for receiving it of the grit arranged by the screw conveyor plate spreader. Further the entire centrifugal spreading unit is preferably from one operating position for one Centrifugal scattering can be removed into a rest position for pure drop scattering, in particular swiveling, more particularly swiveling upwards, so that the spreading material is unhindered due to parts required only for centrifugal scattering in the case of roller scattering or the same fall scatter can be spread evenly.

The at least one separate drive of the centrifugal scattering module is preferably a Hydraulic drive driving screw conveyor. Such is easy to handle because for many vehicles that can be used in winter service or agriculture, and also for many spreaders hydraulic supplies are provided. The supply lines are accordingly hydraulic lines which, according to an advantageous embodiment of the invention, in particular via screw or quick connections to the hydraulic system of the main module and / or a hydraulic supply to the vehicle can be detachably connected are. If further preferably at least two hydraulic drives, one for the A screw conveyor and one for the plate spreader can be provided under certain circumstances both operate at different speed ratios as required. The spreading width is determined by the speed of the plate and by the speed of the screw conveyor To a certain extent, the spread rate can be controlled.

The way in which the centrifugal spreader unit is movable from its operating position can be different, especially because of the modular separation. It can a manually operated locking device, in particular a telescopic rod Safety bolt, for locking the manually from its rest position into the operating position or vice versa moving centrifugal scattering unit can be provided as well a preferably electrically driven spindle, a hydraulic cylinder or the like Automatically operated movement and locking device for automatic Moving the centrifugal spreader between rest and operating position and holding on the same in the selected position.

Many of the combination devices implemented so far have to be seen purely from the drive various moving parts of the centrifugal spreader unit continue to run, even if this is moved from the operating position into a rest position. On the other hand, is a switching element in particular an electrical contact switch acting on a hydraulic control slide, for putting one, several or all drives of the centrifugal spreader unit out of operation, especially the screw conveyor drive when removing the centrifugal litter unit provided from the operating position, so disadvantages - z. B. Loss of energy - and dangers - risk of injury - with possibly folded up and with it more easily accessible moving parts that are not required, be avoided.

When training as a combined roller / plate spreader is in a concrete form preferred if the worm housing in the operating position substantially below the spreader roller for receiving the spreading material from the spreader roller and further conveying the same is arranged by the screw conveyor towards the plate spreader and preferably on detachable bolts on the side of the container housing from the vehicle is pivoted away upward in the rest position.

To optimize the use of the width of the spreader, according to another alternative or additional approach according to the invention in a spreader of the type mentioned that proposed in particular within the container housing through the reservoir, a supply channel or the like implementation from the area to be attached by the vehicle to the vehicle area to be turned away and with supply and / or signal lines, in particular electrical lines for vehicle lighting and hydraulic lines Lines for hydraulic drives, in particular a hydraulic line for the plate spreader drive, through the inner supply channel from the vehicle to the most from the vehicle units located to be turned away.

Just such lines as hydraulic lines and especially their controls are so far past the container housing in known spreaders to the back of the spreader, where there is usually a rear spreader Vehicle tail lights including a license plate light and also the plate spreader located, which must be supplied with energy - hydraulic pressure. This had the unpleasant effect that these lines were relatively vulnerable when the vehicle was on Bushes, signs or similar protruding parts had to pass. At the same time this has pushed up the minimum passage width without any benefit for the maximum spread. These disadvantages are according to the one just described Avoided execution of the invention.

If the supply channel is designed as a longitudinal cavity within a reinforcing strut which is in particular essentially in a longitudinal direction through the Interior of the container housing extends for reinforcement thereof, which reinforcing strut preferably as diagonal from the bottom of the attachment area to the top of the vehicle extending stiffening tube is formed, so are not only the supply lines protected and space-saving - especially width saving - relocated, but at the same time the container housing is reinforced or stiffened. This is particularly advantageous in the case of a platform-mounting device, since there is a stabilizing front wall due to the desired fillability of the grit container the spreader over the loading platform is missing. Then it is particularly preferred that the reinforcing strut or the stiffening tube in the center of the spreader and / or its Container housing is arranged.

The supply lines are further preferred not only in the area of the implementation to the rear of the spreader, but also in the rear if an end area to or away from the vehicle - i.e. the rear area for rear attachment - arranged box for supply lines and / or for supply connections, such as in particular hydraulic, pneumatic and / or electrical Lines and connections are provided, which box with a hood, a lid or preferably a flip-up flap or similar cover for Assembly of units and openable for maintenance purposes in relation to its surroundings is completed. In the box, electrical lines and connections for one Vehicle lighting, hydraulic lines and connections arranged on the spreader for the centrifugal spreader unit, especially the plate spreader, and / or control slide for the hydraulics against weather influences and influence by spreading material sealed housing, for which purpose the flap via a seal on the container housing or attacks a box casing. Such a flap is also Assembly and disassembly of the centrifugal spreader unit or more precisely its connecting lines easy to carry out, the connections still, especially in their Not used, against dirt and weather and in particular also against grit e.g. Road salt - are well protected.

With regard to the design of the plate spreader, it is preferred if it is equipped with a Swivel device to enable an asymmetrical to the longitudinal axis of the spreader Spreading distribution is equipped. Such a swivel device could, for example only for swiveling one covering the plate spreader towards the vehicle Be formed cover, then the remaining area to the left or right is pivotable. The asymmetrical spreading distribution extends further to the preferred spreading side but then when to form the swivel device with the one determined Spreading angle to cover plate spreader provided an essentially pivot axis arranged parallel to the axis of rotation of the spreading disc is pivotally mounted on the screw housing, one in particular a telescopic rod with locking device and several locking positions is provided for the optional locking of the plate spreader in a desired Scattering position.

The bearing elements and, if applicable, the bottom bracket of the spreader roller are for protection Double-sealed self-aligning bearings, preferably against spreading material. Self-aligning bearings have that Advantage that manufacturing tolerances regarding the arrangement of the bearing elements are simple are compensable.

The width of the spreader is equal to the width of the Load platform adjusted so that different for different platform or vehicle types Versions with different widths are provided.

In the illustrated embodiment, the spreader is a combination device with a designed as a roller spreader 1 discharge and drop spreader and a plate spreader 2 and a conveyor screw 3 having centrifugal scattering unit 21.

The roller spreader 1 has a housing forming a storage container 36 for grit 22 on, the rear side wall 30 with lighting required in road traffic 6 and one through a cover 7 - in the form of a swivel opening flap - covered box 23 for the necessary electrical and hydraulic Lines and control devices is provided.

The pivotable on the container housing by means of removable bolts 24 about a horizontal axis 22 of the roller spreader 1 hinged spreader unit 21 has Screw housing 25 with the screw conveyor 3 arranged therein and the hinged to it Plate spreader 2 on. The plate spreader 2 comprises a spreading plate 12, a holder 26, a scattering angle cover 27 and a hydraulic drive 28 for driving the Scatter plates 12.

The holder 26 is pivotable about a vertical axis 29 hinged to the worm housing 25. The swivel device 5 comprises a telescopic rod 17, which as a locking device for locking the plate spreader 2 in different angular positions - see FIG. 2 - by means of a not explicitly shown Locking pin is adjustable.

The scattering angle cover 27 covers the essentially forward-facing area in front of the spreading plate 12 and leaves a scattering angle to the rear. The scattering angle cover 27 is by means of the swivel device 5 together with the entire plate spreader 2 can be pivoted about the axis 29, so that the radiation area of the plate spreader 2 can be selected to set an asymmetrical plate spread.

Between a rear side wall 30 of the roller spreader 1 and the screw housing 25, a flexible protective cover 31 - plastic flaps - is provided, so that the centrifugal scattering unit 21 about the vertical axis defined by the bolts 24 the operating position shown in Fig. 1 in the rest position shown in Fig. 4 is pivotable above. To enable this upward swiveling movement and / or for locking the centrifugal spreader unit 21 in the respective position - operating position see Fig. 5 and rest position see Fig. 4 - is an excavation 4 for the plate spreader 2 provided. This excavation 4 has a telescopic rod in the embodiment shown 47 for locking a manually operated pivoting by means of a Locking pin - locking pin 46 - on. In embodiments not shown points excavation 4 - additionally or alternatively - a hydraulic cylinder or an electrospindle for self-locking automatic lifting and lowering of the centrifugal spreader 21 on. On the side walls 32 are like handles or holding brackets shaped attachments 16 for attaching the spreader 20 to a parking stand (not shown), the easy assembly and disassembly of the spreader 20 on the Vehicle allows, provided.

The parking stand has two interconnected stands, on which to Example can be raised and lowered by means of one lifting spindle and each with one arm upward bolts for gripping the respective attachment 16 are provided. The parking stand is also preferably on (steering) castors, so that on the parking stand suspended spreading device 20 easily towards and away from the vehicle can be moved.

As can be seen from FIG. 3, the roller spreader 1 has inside the container housing 21 a breaker roller or breaker shaft 11 with angled breaker claws for loosening of the grit and a spreader roller 10 for discharging the grit from the container housing 22 on. Both shaft and roller elements 10, 11 are on bearing elements 33, 34 stored, each of which from the side walls 32 into the interior of the container housing 22 stretch in. In the area of the side wall 32 is outside of the storage container 36 formed by the housing 22 for grit only one narrow chain drive (not explicitly shown) for driving the shaft or roller elements of the roller spreader 1 by means of a likewise in the interior of the housing 22 - however preferably arranged outside, for example below the reservoir 36 Hydraulic drive 35, which is indicated in Fig. 4. The bearing elements are through inwardly projecting crusher shaft bearings 33, which are particularly sealed Self-aligning bearings are formed and by inner bearings located within the spreading roller 34 - also self-aligning, double sealed - formed. This extends the effective range of the spreader roller 10 beyond its storage.

4 shows the more precise structure of the container housing 22 with the one arranged therein Storage container 36, the rear drop side 30, the side drop sides 32 with the suspension 16, the box 23 and a front opening 37 for filling the storage container 36 illustrated by tilting the platform with grit. In the front area (attachment area 13) below the opening 37, an angle bracket 38 can be seen, with which the spreader 20 can be placed on the rear edge of the loading platform and on this is supported. From this a floor plate 39 leads obliquely down to the spreader roller 10, where the bottom plate 39 with a first, acting on the spreader roller 10 Scraper edge 40 is provided. The spreader roller 10 is provided with highlights 41, by means of which the grit 42 past a second scraper edge 43 to the outside for a roller spreading (Fig. 4) or towards the screw conveyor 3 (see Fig. 5) for the plate spreading is portable. For a locally defined spreading even of moist fine-grained Scattering material 42 is still a scraper in the area below the second scraper edge 43 14 arranged with a third scraper edge 44.

Further leads from stripping angle 38 in the longitudinal direction, i. H. when attached in Driving direction of the vehicle, a supply channel or a bushing 15 for electrical and hydraulic lines 52 obliquely upwards to the box 23. The Feedthrough 15 is in the illustrated embodiment as a stiffening rectangular tube educated. In addition, the implementation is in the illustrated embodiment 15 led through the middle of the reservoir 36.

In Fig. 4 it is nice to see that the entire centrifugal spreader unit 21 with a screw housing 25, screw conveyor 3 and plate spreader 2 as a modular unit upwards in a rest position is pivotable. The screw conveyor 3 and the plate spreader 2 are included provided their own drives, here: hydraulic drives, so that they are independent of the Drive 35 are movable. An electrical contact switch 45 ensures that when pivoting the centrifugal litter unit 21 at least the drive of the screw conveyor 3 is out of order. The centrifugal spreader unit is in the rest position shown 21 via a locking pin 46, the two telescoping parts of the telescopic rod 47 of the excavation 4 secures, locked.

Through a dotted line there is still a gate 48 to prevent a hand attack indicated on the movable parts 11, 10 of the roller spreader 1.

The modular design of the centrifugal litter unit 21 means that the bolts are removed 24, nibbling off the hydraulic supply lines 49 (see FIG. 5) and unscrewing the flexible protective cover 31 the spreader 20 from a combined roller / plate spreader convertible into a pure roller spreader. The spreader 20 can also initially be designed as a pure roller spreader that can be upgraded with the Spin spreader unit 21 is already prepared.

In Fig. 5, the spreader 20 is in its operating position which enables plate spreading shown. The spreader module or the spreader unit 21 is off the rest position shown in Fig. 4 pivoted down into its operating position, so that the screw conveyor 3 is in the spreading area of the spreading roller 10. That from the spreading roller 10 is spreading material at the latest when stripped by the third Scraper edge 44 - scraper 14 - stripped from the spreader roller 10 and falls into the trough-like Screw housing 25. The screw conveyor 3 is in a manner known per se opposing spiral screws that cover the entire width of the Spreading roller 10 in the worm housing 25 scattered material 42 towards the center and transported over a chute 50 to the spreading plate 12 of the plate spreader 2.

The screw conveyor 3 and the spreader plate 12 are provided on the centrifugal spreader unit Hydraulic drives 28 (the drive of the screw conveyor 3 is not explicitly shown) drivable. The hydraulic supply lines 51 required for this are over Hydraulic lines 52 and hydraulic connections 53 within the box 23 to a hydraulic supply of the roller spreader 1 and / or a hydraulic supply to the vehicle connected. The contact switch 45 is in the operating position and releases the corresponding control spool of the respective hydraulic supply.

The attachment of the spreader 20 to the tipper platform can be the same depending on the training be different. There are attachments of the spreading device 20 for attachment fastening eyelets and / or provided on the rear side of the loading platform Tension chains or other tension possible.

The rear area 54, d. H. end area to be turned away in the vehicle Box 23 is over the cover 7, which is hinged to hinges 55 and manually Actuable screws 56 is screwed on, easy for attaching and detaching the hydraulic supply lines 51 and accessible for maintenance purposes. Reaches for sealing the cover 7 of the box 23 via a rubber seal 57 on the rear housing side wall 30 on.

In embodiments not shown, there are also supply lines for an automatic one Excavation 4 preferably within the box 23 to appropriate controls connected and from the cab of the vehicle for lifting or lowering the centrifugal litter unit 21 can be operated. It is also conceivable to pivot the Disc spreader 2 around the vertical axis 29 automatically from the driver's cab, e.g. B. about training the swivel device 5 as a hydraulic cylinder or electrospindle from the cab train remotely.

In Fig. 5 only hydraulic lines leading to the disk drive 28 are indicated. In of a concrete design, however, a feed line leads, for example, to the screw conveyor drive, then there is a connecting line between screw conveyor and Spreading disc drive 28 and from there there is again a line - for example a derivative - led to box 23.

In particular, in that the bearing elements 33, 34 run across the container housing 22 running shafts or rollers 11, 10 projecting inwards - that Bearing 33 of the breaker shaft 11 protrudes z. B. about 30 mm into the reservoir 36 the entire platform width can be used. In the spreading roller 10, the bearing 34 is in the roller 10 built into it.

The centrifugal litter unit 21 is for example with handles, not shown, for the manual lifting trained, alternatively or additionally is also a folding up Centrifugal spreader 21 possible hydraulically or with electrospindles. With mechanical Folding up is the locking via the telescopic rod 47 and the Locking pin 46 is provided. Only the hydraulic lines look out of the box 23 51 to supply the drives of the screw conveyor 3 and the spreading plate 12 out.

To remove the centrifugal litter unit 21, the first is through a plastic flap formed flexible fastened with screws to the centrifugal scattering unit 21 Protective cover 31 released, then the bolts 24 and the hydraulic lines 51/52 solved. The centrifugal spreader unit 21 can then be removed, i. H. the Centrifugal litter unit is removed together with the screw conveyor 3. The rest remains then only the main module of the spreader then configured as a roller spreader 1 20; i.e. the roller spreader 1 with the housing 22.

Some notable aspects of the spreader described here are described below summarized again with the aid of FIG. 3:

A spreading device (20) has been described for attaching or attaching to vehicles, in particular for mounting on a usable as a storage container for grit (42) Loading platform of a platform vehicle, with a container housing (22) for receiving of spreading material (42) and a discharge and drop spreading device (1) for discharging the Spreading material (42) from the container housing (22) and for spreading the spreading material (42) with defined spreading width, the discharge and falling spreading device (1) at least one extending across the container housing (22) roller or shaft (10, 11) for Loosening, conveying and / or discharging the spreading material and the spreading device (20) for Inclusion of an optional one for spreading the drop spreading device (1) broader but less defined spreading of the from the container housing (22) discharged spreading material (42) actuatable centrifugal spreading unit (21), which a can preferably be supplied with discharged material (42) by means of a screw conveyor (3) Has plate spreader (2) is formed.
