Vehicle for cleaning a flood zone

The invention relates to a vehicle for cleaning a floodplain.

The flood line is particularly common on the German west coast in large sections on evergreen vegetation in the area of a dike; however, it can also run on sand on a beach.

In both cases, the aim is to collect harmful or non-decomposing debris washed up from the sea, some of which consists of waste materials, and to recycle it properly or dispose of it in a landfill.

On the other hand, natural floating matter such as seaweed, small pieces of wood or the like can remain in place, and in most cases this is even desired, so that other plants can settle there and animals can have a natural living environment.

However, given today's personnel costs, it is no longer reasonable to expect personnel patrolling the beach to search through the floating sea and, if necessary, take rubbish to collection points. The task of cleaning the tide line should be simplified and made easier using technology wherever possible.

According to the invention, this is achieved by a vehicle with the features of the main claim. The subclaims give advantageous embodiments of the invention.

It is particularly advantageous that a vehicle with a pick-up unit or other collection device transfers the floating egg to a conveyor belt and places it on a work platform located on the vehicle in a position that is advantageous for sorting by people or, if necessary, machines; organic and natural material is separated from the waste to be collected and then the organic and natural material (such as sand, stone or the like) is removed again on site or onto a trailer.

&BpEHMBRT*;

Because a distributor, e.g. a tedder, pulls the collected material apart again in a wide pick-up after it has been brought together from the side and loosens it up, a part to be sorted out can be easily removed from the previously tangled floating material on the conveyor belt or transferred to the appropriate collection container.

Because the tines are arranged loosely on the tedder, even long pieces of wood can be conveyed onto the conveyor belt without any problems. A further drop step between two sections of the conveyor belt allows further separation and, in particular, turning of the material being conveyed, which makes it possible to look at the other side and possibly to sort it out based on the properties of the back. Alternatively, a turning drum or something similar can be provided instead of a drop step.

The material that has not been sorted out is then fed into pre-press rollers and then into a flail shredder. The advantage of this is that flail shredders are insensitive to foreign bodies such as stones or the like. All organic or natural material is therefore returned to nature, so that there are no deficits in the natural cycle.

Collection containers arranged next to the conveyor belt can be removed separately and, if necessary, full containers can be exchanged for empty containers at collection points. The width of the vehicle, which does not need to exceed the usual road transport width, usually allows the entire floodplain to be crossed in one drive.

However, if necessary, the processed width can be doubled by moving back and forth.

At the same time, a weather shelter, which is formed behind a fixed driver's cabin of the vehicle under an existing roof section by the side walls made of PVC tarpaulin with integrated panes, provides effective weather protection for sorting personnel even in bad weather.

In the event that, for example, the organic material on a bathing beach is not to be returned immediately, a trailer can be attached underneath a discharge arch located at the rear of the vehicle in order to remove the discharged material from the beach if necessary. This means that the vehicle can even be used to collect large stones on a fine sandy beach.

The raised cabin between the two front wheels allows the driver to look in front of the pickup truck in order to follow the course of the floodplain. At the same time, he can keep an eye on the wheels in order to be able to navigate difficult contours in the terrain, for example, to drive over plank bridges over gullies or similar without any problems.

Wide tires (terra tires) with not too high studs are recommended as the chassis in order not to damage the grass, especially in the dyke area, but for special soils a crawler chassis with rubber tracks can also be used.

In order to enable the widest possible intake and at the same time to sort on a narrow conveyor belt,

jfetjEttMEItT &&Bgr;&Ogr;&Egr;«&Mgr;|&iacgr;&pgr;;:

It is suggested to install a conveyor roller with a screw conveyor after the thick, leading tines of the pickup. Any compression caused by this is canceled out by the tedder.

Further features and advantages of the invention emerge from the following description of a preferred embodiment based on the accompanying drawing. It shows:

Fig. 1 the vehicle according to the invention in side view, and

Fig. 2 shows the vehicle according to the invention in plan view.

The vehicle shown in Fig. 1 is provided with a raised driver's cab 10 above front tires 12, a central working platform 14 and chopping 18 and ejection 20 devices arranged above rear tires with a reduced radius. A collecting device provided in the front area, such as a pick-up 22, consists of a row of tines 24 directed essentially horizontally towards the front, a screw collecting guide 26, to which a conveyor roller 28 is connected in the middle area, which passes the collected material on to a tedder 30.

To support the pick-up, wheels 32 can be provided, extending essentially as far as the ground as the movable tines 34 of the pick-up reach. Above the tedder conveying material onto the conveyor belt 36, a cover 38 is provided, which limits excessive ejection. The entire pick-up is supported by a

Hydraulics, which are advantageously operated with bio-oil, can be lifted.

The conveyor belt will extend inside the vehicle above the worktop up to working height, slightly slanted to a central area, from where a step leads to a lower second section 42, which is advantageously also designed as a conveyor belt in order to feed the now sorted material to a shredder 18. A flail shredder is advantageously used, which is insensitive to foreign objects, such as stones. To promote the shredding effect, a pre-press is carried out beforehand between pre-press rollers 44. The flail shredder will simultaneously convey the ejected material backwards through the ejection arch 20, with a movable section 46 at the end of the ejection arch in order to influence the ejection direction if necessary downwards in order to convey it in a towed trailer.

To pull a trailer, a trailer coupling 48 is arranged below the shredder, as can be seen in the illustration.

Finally, the top view shows the collection containers 50, which are arranged in the area of the treads. Operating personnel can stand on the treads while sorting plastic material and other undesirable items from the drifting sea in order to grab the drifting sea parts that are to be transported into the collection containers 50 at an optimal working height without having to bend down.

In good weather, only a roof 54 will be used, while in bad weather, weather protection tarpaulins

·· &Ggr;&eegr; _

56 with integrated window surfaces 58 on the sides to seal the vehicle interior against wind and rain.

Finally, reference number 60 represents the motor transmission unit of the vehicle, whereby an automatic transmission is to be provided, which ensures slow movement of the vehicle with three gears in the ranges 0-5 km, 0-12 km, 0 - 20 km. The driver's cabin is advantageously provided with fixed windows all around so that he has a good all-round view. At least this cabin should also be heatable.
