Description

The invention relates to a vehicle for beach cleaning with a vehicle frame, at least one wheel axle arranged thereon, with a height-adjustable waste pickup, a adjoining latter, the waste taken over from the waste pickup to a conveyor arranged at the rear end of the vehicle frame (such as from the EP -A-0 387794) and a feed rotor assigned to the feed area of the garbage collector.

Such a beach cleaning vehicle is also known from US-A-4,482,019. From a feed rotor formed with prongs, waste from the ground is z. B. a sandy beach and transferred to a conveyor belt. The tines of the feed rotor are curved at their ends in the direction of travel, the rotor rotates in the same direction.

A disadvantage that the impurities must be included in the driving direction from the substrate and at least passed over a range of 180 ^o about the feed rotor. Contaminants thrown forward by the tines partially hit a rotor housing, sometimes fall back onto the beach, get back in front of the feed rotor and have to be taken up again.

The speed of rotation of the rotor is added to the driving speed in the receiving area, so that the waste is thrown tangentially forward in the direction of travel when it comes into contact with the tines. In this way, contaminants can accumulate in front of the feed rotor and impair further use.

The tines are heavily loaded when they hit the dirt or sand due to the high relative speed and can break.

Fibrous impurities such as algae can wrap around the feed rotor and the sinks and become matted with them due to the rotation of the feed rotor and the long entrainment until delivery to the conveyor belt. In the case of increased algae contamination, the known feed rotor must frequently be cleaned and freed from the algae.

Due to the formation of the feed rotor and its assignment to the conveyor belt, only impurities that the rotor detects are absorbed by the beach. Contaminants not picked up by the feed rotor can no longer be picked up by the conveyor belt and remain on the beach.

To adjust the height of the feed rotor, the entire vehicle frame with all the devices attached to it is lowered. The wheels mounted on a bracket-shaped bracket are pivoted backwards by an actuating device and the entire vehicle is thereby lowered. A height adjustment of the feed rotor relative to the conveyor belt is not possible. The distance between the feed rotor and the conveyor belt cannot be varied. Bulky impurities cannot be picked up and may damage the vehicle.

A separation of impurities and sand takes place in the previously known beach vehicle only with the help of a sieve belt arranged after the conveyor belt. It must have both the contaminants and the sand transport. This can put a heavy load on the vehicle, particularly in the case of damp sand. In addition, part of the sand with the impurities is transported to the collection container. The collection container is filled prematurely and must be exchanged for another container or emptied.

The invention has for its object to provide a vehicle for beach cleaning of the type mentioned, which is improved when feeding, picking up and transporting waste and when separating the waste from the sand and when disposing of the contaminants.

This object is achieved in a vehicle for beach cleaning with the features of the preamble of claim 1 in that a swivel frame carrying the garbage collector and the feed rotor for height adjustment is lowered on the vehicle frame, on which the feed rotor by means of a handlebar over a different operating positions swiveling range from the front is pivotally mounted to the rear and can be rotated, in particular counterclockwise, about a horizontal axis of rotation mounted on the links.

The feed rotor is arranged in a first, front operating position for feeding garbage and / or sand to the waste pickup in the direction of travel in front of a receiving wedge strip arranged at the front of the waste pickup, in a second, middle operating position the distance between the receiving wedge strip and the feed rotor is minimal and in one In the third, rear operating position, the feed rotor is arranged at a greater distance from the receiving wedge strip or from the waste pickup above compared to the second operating position.

According to the invention, therefore, it is not necessary to lower the entire vehicle frame for height adjustment of the garbage collector, but only the swivel frame. Depending on the application, the waste pick-up is lowered down to or into the sand with the holding wedge strip. The impurities and possibly sand are absorbed via the wedge ledge. At the same time, the feed rotor is also lowered. Since this is pivotably mounted relative to the waste pickup, both the distance from the feed rotor to the waste pickup or wedge bar and the height of the feed rotor relative to the sand can be varied independently of the waste pickup.

In a first operating position, the feed rotor is arranged in the direction of travel in front of the wedge bar and thus also in front of the waste collector. If in this position the wedge bar rests roughly on the sand, the feed rotor rotates above the sand or penetrates the sand surface only slightly. In this position, the feed rotor feeds all surface contaminants to the waste collector. Only a small amount of sand is taken up and therefore a high driving speed is possible. In addition, since the rotor rotates counterclockwise, the rotation speed and the vehicle speed do not add up, which leads to a lower load on the rotor. This throws the impurities in the direction of the wedge ledge and garbage collector, at the same time a partial separation of the contamination occurs depending on its weight. Lighter impurities are thrown further towards the waste collector than heavier ones, e.g. B. sand.

Any impurities not detected by the feed rotor are subsequently removed by the Wedge ledge picked up and passed on to the waste collector. In this way, all debris is absorbed by the beach up to a certain immersion depth and this is cleaned intensively.

The first operating position is particularly advantageous in the case of wet sand or in the flood zone area, since only a small amount of sand is absorbed and the surface is cleaned thoroughly.

In the case of dry sand, the second operating position of the feed rotor is preferably used. In this position, the rotor not only serves to supply contaminants to the waste collector, but also to accelerate the sand and the contaminants taken up by the wedge bar. The wedge bar is partially immersed in the sand. The feed rotor forming a channel with the wedge ledge partly covers the sand and in particular the garbage lying superficially on the sand. Similar to the first operating position, the rotor throws the materials in its rotating area towards the waste collector. The lighter parts are thrown further than the heavier parts. In this way, sand and impurities are already partially fed to the waste collector and are easier to separate from each other on this. At the same time, the accelerated forwarding of the materials picked up enables a higher driving speed.

In the third operating position, it is particularly possible to accommodate bulky parts. Since the distance between the feed rotor and the wedge bar or garbage collector is relatively large, the wedge bar can recorded parts are carried out in the gap formed between the rotor and the wedge bar to the waste collector. The rotation of the rotor supports further transport.

The contaminants, which are largely separated from the sand by the feed rotor and the waste pickup, are almost completely freed of any sand that may have been transported on the subsequent conveyor and fed to the collecting container.

The features of claims 2 and 3 are also advantageous, since in this way the swivel frame is of simple design and is arranged completely below the vehicle frame. The top of the vehicle frame can also be used in a variety of ways, such as. B. for transporting building material, soil, nursery items or the like. The swivel frame itself can be lowered by the storage at its rear end with its end lying in the direction of travel. At this end feed rotor and wedge bar are arranged.

The features of claims 4 and 5 are advantageous in that a versatile use of the vehicle is possible in this way. The swivel frame can be exchanged together with the waste pick-up and feed rotor with the help of detachable quick-release fasteners for another swivel frame with corresponding devices. Converting the vehicle to other areas of application is possible without spending a lot of time. This increases the flexibility of the vehicle. For example, use for cleaning asphalt roads is also possible, in which case the receiving wedge strip is preferably elastic and the feed rotor is designed in particular as a brush roller is. The vehicle can also be used for general transport without a swivel frame.

The features of claims 6 to 9 are also advantageous, since in this way the refuse collector can be used for many areas of application. The contaminants are taken over by the elevator from the feed rotor or the wedge ledge and passed on to the downstream conveyor. If the elevator has its own drive, its speed can be set independently of the speed of rotation of the feed rotor or the speed of the conveyor and can be easily adapted to applications with different amounts of waste.

The construction of the vehicle according to claims 10 to 12 is also favorable. The draw-in area of the wedge ledge, feed rotor and garbage collector can be designed according to the vehicle width. The width of the waste stream is reduced in accordance with the specified conditions via the arranged side coulters and guide plates and is thus, for. B. between the wheels attached to the wheel axle. The contaminants are absorbed before they are possibly compacted with the wheels of the vehicle or even pressed into the ground, and the sand is cleaned across the entire width of the vehicle. In principle, a larger width would be z. B. the wedge bar possible, but this would complicate the handling of the vehicle and people may be injured by the ends of the wedge bar protruding laterally from the vehicle contour.

The features of the protection claims 13 and 14 are advantageous in that with the help of the adjusting device e.g. B. automatically controlled lowering and lifting of the swivel frame is possible. The actuating device can be designed as a hydraulic actuating cylinder and z. B. be operated remotely by the driver of the vehicle. In order to be able to use the entire width of the swivel frame for the refuse collector, the adjusting device is arranged on the side of the frame.

Furthermore, it is advantageous if the angle of incidence relative to the garbage pickup of the receiving wedge strip is greater than the angle of incidence of the garbage pickup. In this way, in the second operating position between the receiving wedge strip and the feed rotor, a narrowing transport channel is obtained for the further transport of waste and sand that has been taken in, the end of the transport channel having a larger opening angle and the material taken up thereby being better distributed over the waste collector.

In addition, a further development of the vehicle according to claims 16 to 18 is appropriate. With the help of the impact cladding, material that may be thrown upward or potentially thrown out over the waste collector is intercepted and directed back onto the waste receiver. At the same time during impact z. B. chunks of sand, which facilitates a subsequent separation of garbage and sand on the garbage collector or the conveyor. In particular, the height of the impact cladding, which decreases in the direction opposite to the direction of travel, prevents the garbage or sand from being thrown away over the garbage collector. In addition, the cover of the impact lining serves as a stop when swiveling the swivel frame back in the direction of the vehicle frame and for mounting the rotor swivel axis.

Advantageous embodiments of a feed rotor suspension can be found in claims 19 to 21. By using the U-shaped frame, the feed rotor is suspended in principle in a pendulum shape with the help of the frame. With the help of the flange bearings protruding from the U-web and the corresponding bearing tabs protruding from the cover, the entire frame can be pivoted about the pivot axis.

The rotor is thus easily accessible. In addition, the arrangement of the flange bearings and bearing brackets makes it very easy to swivel over the swivel range encompassing the operating positions. The swivel radius of the feed rotor is relatively large, and yet it is possible to swivel the swivel frame close to the vehicle frame, with flange bearings and bearing brackets of the rotor being arranged laterally next to the vehicle frame. Due to the special bearing of the rotor axis of rotation, a fine height adjustment of the rotor is also possible.

In order to adjust the rotational speed of the feed rotor independently of other devices, it is also advantageous if a drive device is assigned to one end of the rotor axis of rotation. This can be a hydraulic motor that is connected to the hydraulic system of the vehicle and can be adjusted by the driver if necessary.

The features of claims 23 and 24 are also advantageous, since the actuating device for pivoting the rotor allows it to be pivoted independently of the waste pickup. The actuator can, for. B. be designed as a hydraulically actuated piston. So that no greater leverage occurs, the Actuator attached with one end close to the rotor axis of rotation. In order to further facilitate the pivoting, the other end of the adjusting device is arranged on a side wall of the impact cladding.

In an advantageous embodiment, the feed rotor has a plurality of radially projecting tines which determine the rotor circumference. With the help of the tines, the impurities or the sand are thrown in the direction of the wedge ledge or the waste collector. The tines can be designed as elastic tines made of metal or plastic which are fixedly arranged on the axis of rotation of the rotor. It is also possible to store the tines spring loaded.

In order to achieve a minimum distance between the wedge bar and the rotor axis of rotation in the second operating position and to optimize the transport effect of the rotor in this position, it is advantageous if the receiving wedge bar extends in the direction of travel essentially in a direction parallel to a tangent of a pivoting curve, the pivot curve being determined as the envelope of a part of the rotor circumference lying opposite the pivot bearing.

Advantageous arrangements of feed rotor and wedge bar result from the features of claims 27 to 30.

The features of the protection claims 31 and 32 are advantageous in that an additional separation of the waste from the carried soil material is possible with the aid of the conveyor. In order to prevent contamination or damage to the wheel axle and all lines arranged below the conveyor, a baffle plate must be installed above the rear axle advantageous. A deflection axis can be designed as an unbalanced shaft on the conveyor as well as on the garbage collector and can make shaking off the sand or the soil material easier by means of a targeted oscillating movement that runs vertically to the transport direction.

To mount the actuating devices of the swivel frame, it is advantageous if the front cross member of the vehicle frame laterally protrudes beyond the longitudinal members to approximately the vehicle width and the actuating devices are supported at its ends. At the same time, tipping devices for a loading area arranged on the vehicle frame can also be mounted at these ends. In one embodiment, the vehicle frame is essentially formed by a frame rectangle formed by two long beams and two cross beams and a frame triangle arranged at its front end. A coupling device for a towing vehicle is arranged at the top of the frame triangle.

In order to obtain the largest possible loading area, it is advantageous if the loading area extends almost completely over garbage receptacles and conveyors. The collecting container can be pivoted over the leather surface by means of two supports arranged on the side of the vehicle frame or on the leather surface and can be emptied evenly onto the leather surface.

In addition, the features of the protection claims 35 to 37 are advantageous in that with the aid of the rocker arms, a uniform pouring out of the collecting container is possible over the entire length of the loading area. The first garbage is placed over a pouring edge of the collecting container emptied onto the loading area directly above the rear end and gradually pivoted further by the arrangement of the tilting link and carrier of the collecting container during the pivoting to the front end of the loading area. Due to the triangular connection frame, the carrier of the collecting container can be rotated from a substantially horizontal position into an approximately vertical position with the aid of a tilting device. Both the tilting device for the collecting container and the tilting device for the loading area can be designed as hydraulically actuated pistons.

A further development of the vehicle according to claims 38 to 40 is also expedient. A height adjustment of the rear end of the vehicle is possible due to the wheel axle designed as a lift axle. In particular for emptying the loading area, the vehicle frame is raised with the aid of the lifting device and the collected garbage can also be tipped into a higher container.

In Figure 1, the vehicle according to the invention for beach cleaning 1 is shown together with a towing vehicle 2. The beach cleaning vehicle 1 is connected to the latter by means of a coupling device 3 and a coupling device 77 formed on the towing vehicle 2 and is movable over a base 68. The vehicle 1 is essentially from the Vehicle frame 4, a folded-up loading area 5, a swiveling frame 7 arranged under the vehicle frame 4 and a collecting container 6 pivoted over the loading area 5 are formed.

The coupling device 3 is arranged on the vehicle frame 4 at its front end and an essentially horizontal tilting axis 51 for the loading area 5 is arranged at its rear end. The loading area 5 is pivoted upward about 45 ^° relative to the vehicle frame 4 about the tilt axis 51. At its rear end, an adjustable rear wall 50, which is pivotably mounted at the rear upper end of the loading area 5, is partially open. A collecting container swiveling device 39 is arranged on a side wall 87 of the loading area near the underside facing the vehicle frame. This runs essentially parallel and closely adjacent to the underside of the side surface 87. The pivoting device 39 is mounted on the side surface 87 at a front end 40, while the rear end 41 is mounted on the tip of a triangular frame element 48, 49. The ends of the legs 48 and 49 of the triangular frame element are connected to a carrier 42. This and the triangle legs enclose an essentially equilateral triangle. In the vicinity of the connection between the triangular leg 48 and the carrier 42, the latter is pivotably mounted on the underside of the side wall 87 of the loading surface 5 at its end 43. At the opposite end 44, the collecting container 6 is pivotably mounted relative to the carrier 42. The end 44 of the carrier 42 is arranged approximately in the center of gravity of a side surface of the collecting container 6. A cross member 45 extends at right angles to the carrier 42 along the collecting container 6.

A rocker arm 46 is rotatably mounted on the side wall 87 of the loading surface 5 adjacent to the end 43 of the carrier 42. The bearing point 164 of the rocker arm 46 is shown in FIGS. 2 and 3 and is offset relative to the bearing point 43 of the support 42 in the direction of the upper edge of the side wall 87. At the other end 47, the rocker arm 46 is rotatably mounted on the collecting container 6. This end lies essentially offset on a straight line which runs vertically to the bottom surface and runs through the end point 44 of the carrier 42 in the direction of the top of the collecting container 6. The rocker arm 46 is formed with a somewhat shorter length than the carrier 42.

With the aid of a loading surface tipping device 36, which is arranged between a cross member 35 of the frame 4 and the side surface 87 of the loading surface 5, the latter is pivoted relative to the vehicle frame 4. The tilting device 36 is rotatably supported at one end 37 on the cross member 35 and is arranged at the other end 38 approximately above the end 43 of the carrier 42 in the center of the side wall 87.

Opposite the end 37 of the tilting device 36, an actuating device 32 with one end 34 is rotatably mounted on the cross member 35. With its other end 33, it is rotatably mounted on a swivel frame 7 arranged below the vehicle frame 4.

With the aid of the adjusting device 32, the swivel frame 7 can be lowered in the direction of the floor 68 about an essentially horizontal swivel axis 8 arranged in the vicinity of its rear end. A number of rollers 20, 21, 24, 25, 26, 27 and 28 are rotatably mounted in the swivel frame 7. The rollers 20 and 21 serve as deflection axes for a conveyor belt formed from upper run 22 and lower run 23. The rollers 24, 25 and 26 are designed as support rollers and, together with the deflection axes 20 and 21, define a transport plane of the upper strand 22. The rollers 27 and 28 are each arranged between the deflection axes 20 and 21 and the support rollers 24 and 26 adjacent to them. They are offset downwards from these rollers and are not in contact with the upper strand 22. The rollers 27 and 28 serve as tensioning rollers and are arranged below the lower run 23 and guide it in the direction of the upper run 22. The lower run 23 between the tensioning rollers 27 and 28 sags in the direction of the bottom 68.

A baffle cover 15 is arranged on the swivel frame 7 above the deflection axis 20 and the support roller 24. This points from the swivel frame 7 in the direction of the vehicle frame 4. In the swiveled state of the swivel frame 7 shown in FIG. 1, a cover 16 of the impact lining 15 with the underside of the vehicle frame 4 is in contact over its entire length. At the rear end of the impact cladding 15, the end 33 of the actuating device 32 is arranged near the swivel frame 7. Arranged between the end 33 and the end 8 of the swivel frame 7 mounted on the vehicle frame 4 is a guide plate 65 which extends in the longitudinal direction of the swivel frame and extends above the upper run 22.

For pivoting the rotor, an adjusting device 29 extends between a rear upper edge of the impact cladding 15 and a feed rotor 11 arranged in front of it. It is mounted at its rear end 31 on the impact cladding 15 and at its front end 30 on the feed rotor 11.

The feed rotor 11 is rotatable about an axis of rotation 18. It has a plurality of radially projecting tines 67. A drive device cover 17 extends between the axis of rotation 18 and the vehicle frame 4. This partially projects laterally beyond the vehicle frame 4. A bearing bracket 19 is directed toward the upper end of the cover 17. This is arranged on a front edge of the cover 16 of the impact lining 15.

Directly below the feed roller 11, a side sheet 64 partially covering this laterally is arranged as an extension of the swivel frame 7. The height of the side coulter 64 corresponds approximately to the height of the end of the swivel frame 7 that is adjacent to it above, wherein it runs approximately parallel to the opposite end of the swivel frame 7 pointing towards a conveyor 12.

The conveyor 12 is arranged between the wheel axle 13 and the vehicle frame 4. It has an inclination essentially corresponding to the swivel frame. A run 58 formed from upper and lower run runs over deflection axes 52 and 53, as well as over support rolls 54 and 55 and tensioning rolls 56 and 57. The transport direction of the conveyor 12 and of the waste pickup 9 arranged in the swivel frame 7 is the same and in the direction of the rear end of the vehicle 1 directed. Similar to the swivel frame 7, the conveyor 12 also has side-guiding plates 66.

In Figure 1, the vehicle frame 4 is shown lifted relative to the wheel axle 13. Two support arms 62 and 63 connected to the vehicle frame 4 point from the vehicle frame in the direction of the wheel axis 13. A lifting cylinder 61 is arranged centrally between them. A lifting piston 60 is almost completely extended from the lifting cylinder 61, with a holding part 59 partially encompassing the wheel axle 13 being arranged at its end. This has a cross section similar to an isosceles triangle. The reciprocating piston 60 is connected in the center to the base of this triangle.

By lifting the vehicle frame 4 with the aid of the lifting device 60, 61, the wheel 14 is almost completely visible.

A height-adjustable adjusting wheel 162 for parking the vehicle 1 is arranged near the coupling device 3 perpendicular to the vehicle frame 4.

FIG. 2 shows the beach cleaning vehicle 1 with the pivot frame 7 lowered to the floor 68. The same parts are provided with the same reference numerals as in FIG. 1 and are only mentioned in part.

The loading area 5 is placed on the vehicle frame 4 in this figure. When actuated, the tilting device 36 moves its end 38 along the circular arc 72, the loading surface 5 assuming approximately the position shown in FIG. 1 at the end of the circular arc. The tip 41 of the triangular frame part can be guided along the semicircular arc 71 with the aid of the collecting container swiveling device 39. During the The position of the collecting container 6 shown, which is pivoted as far as possible over the loading surface 5 and the triangular tip 41 points in the direction of the pivoting device 39, is in the position of the collecting container 6 shown in FIG. 2, this near the bottom 68 below the rear deflection axis 53 the conveyor 12 arranged. When the collecting container swiveling device 39 is actuated, the center area 44 of the collecting container 6 moves along the circle 69 to the position of the collecting container 6 '. At the same time, the end point 47 of the rocker arm 46 moves along the arch 70. Due to the relative arrangement and length of the carrier 42 and the rocker arm 46 described in FIG. 1, the corresponding guide arch 69 and 70 intersect and the open end of the collecting container 6 is more and more pointed Direction of the loading area 5 and can be emptied via a pouring edge 161 in the direction of the loading area 5.

The swivel frame 7 is lowered around the laying point 8 at one end to the floor 68. A receiving wedge strip 10 arranged below the feed rotor 11 on the swivel frame 7 touches the bottom 68 with its free end, and the side sheet 64 runs with its underside essentially parallel to the bottom.

When the swivel frame 7 is lifted off in the direction of the vehicle frame 4 with the aid of the actuating device 32, its end 33 mounted on the swivel frame 7 can be guided along the arch 73. Furthermore, the axis of rotation 18 of the feed rotor 11 can be pivoted with the aid of the adjusting device 29 over the swivel area 74. In the arrangement of the feed rotor shown in FIG. 2, it is in a second operating position, while the positions 11 ′ and 11 ″ are in a first and a third position Correspond to the operating position. These are explained in more detail in FIGS. 8 to 10.

Compared to the illustration of the vehicle frame 4 lifted in FIG. 1, in FIG. 2 the wheel axle 13 is mounted directly at the ends of the support arms 62 and 63 and the vehicle frame runs essentially horizontally.

In Figure 3, the beach cleaning vehicle 1 is shown in a plan view. The vehicle frame 4 has a triangular frame section connected to the coupling device 3 and a rectangular section section adjoining this. The triangular frame section is formed by two supports 81 and 82 running symmetrically to the longitudinal direction 100 of the coupling device 3 in the direction of a first cross member 35. The triangular tip is arranged in the coupling device 3, while the triangular base is formed by the cross member 35. Parallel to the longitudinal axis 100 are connected to the beams 81 and 82, longitudinal beams 75 and 76. The rectangular frame section is formed by these beams, the cross beam 35 and a cross beam 78 arranged near the vehicle end. The longitudinal members 75 and 76 are at a distance corresponding to the distance between the wheels 14 and 14 '. At its rear ends 51 and 51 ', the loading surface 5 is pivotally mounted, these ends projecting beyond the cross member 78 to the rear. While the cross member 78 extends from one longitudinal member to the other, the longitudinal member 35 parallel to the latter has a greater length. With its ends 79 and 80, it protrudes on both sides of the side members by the same length in each case. At the outer ends of the cross beam ends 79 and 80, the actuators 32 and 36 are pivotally mounted.

Above the frame 4, the loading area 5 is arranged lying thereon. In the top view shown in FIG. 3, a front wall 88, two side walls 87 and 89 and a rear wall 50 can be seen from the loading area 5. The side walls or front and rear walls are parallel to the longitudinal beams 75 and 76 or cross beams 35 and 78 and form the rectangular loading area 5. The rear wall 50 runs, as shown in FIG. 2, at an angle to the vertical towards the rear toward the collecting container 6. While the upper edge of the rear wall 50 is arranged in front of the collecting container, the lower edge closer to the collecting container is arranged above an opening 90 of the collecting container 6. The pouring edge 161 is thus located below the loading area 5. The pouring edge and its opposite side of the collecting container run essentially parallel to the rear wall 50. The extent of the collecting container 6 perpendicular to the longitudinal direction 100, ie its width, is slightly shorter than the inner distance between the side walls 87 and 89 of the loading area. On the transverse sides, the collecting container 6 is connected in the center via the bearings 44 and 44 'or 47 and 47' to the carrier 42 and 42 'or the rocker arms 46 and 46'. The brackets 42 and 42 'run parallel to the rocker arms 46 and 46' outside the side walls 87 and 89. At their ends 43 and 164, both the brackets 42 and the rocker arms 46 are with the side wall 87 and correspondingly on the other side with the side wall 89 connected. Laterally outside and parallel to this, collecting container swiveling devices 39 and 39 'are arranged on the side walls 87 and 89. The pivoting device 39 runs between a first bearing point 40 and a second bearing point 41. This is above the carrier 42 according to FIG. 1 and 2 designed as a triangular tip. The distance from the carrier 42 and the collecting container swiveling device 39 to the side wall 87 is essentially the same. The same applies to the collecting container swiveling device 39 'on the other side wall 89 of the loading area 5.

In front of the front wall 88, a hydraulic cover 91 is arranged on the triangular frame section formed by the supports 81 and 82. This extends symmetrically to the longitudinal direction 100, with its side surfaces running essentially parallel to and projecting above the supports 81 and 82.

Below the hydraulic cover 91 and under the frame 4, the cover 16 is arranged symmetrically to the longitudinal direction 100. On both sides, it protrudes somewhat relative to the side walls 87 and 89 of the loading area 5, the adjusting devices 29 and 29 'being arranged on these sides. The distance between these adjusting devices essentially corresponds to the distance between the collecting container pivoting devices 39 and 39 'or the distance between the supports 42 and 42'.

At the front end of the cover 16 100 bearing tabs 19 and 19 'are arranged symmetrically to the longitudinal direction. These are in engagement with bearing devices 85 and 86 of a frame 84. The frame 84 runs parallel to the front of the cover 16 and projects beyond it laterally through two arms directed in the direction of the adjusting devices 29 and 29 '. The drive device cover 17 is arranged on one side of the frame 84, with a motor 83 protruding from the cover 17 in the direction of the longitudinal axis of the frame 84.

In Figure 4, the beach cleaning vehicle 1 is shown in a plan view of the garbage collector 9, the conveyor 12 and the collecting container 6.

Both the run 22 of the garbage collector 9 and the run 58 of the conveyor 12 are designed as sieve belts. These have a plurality of essentially diamond-shaped openings.

On the front of the vehicle 1, two side coulters 64 and 64 ′, which are angled outward symmetrically to the longitudinal direction 100, are arranged at the ends of the wedge strip 10. The receiving width 92 of the side coulters 64 and 64 'essentially corresponds to the vehicle width 93. The wedge ledge 10 protrudes from the waste pickup 9 approximately over half the longitudinal extent of the side coulters 64 and 64' in the direction of the coupling device 3. At the rear ends of the side coulters there is Spacing slightly smaller than the width 95 of the upper run 22 of the garbage collector 9. Adjoining plates 96 and 97 running on both sides symmetrically to the longitudinal direction 100 adjoin these ends. These run parallel to the longitudinal direction 100 via a section directly adjoining the side shares 64 and 64 ', while they converge in the subsequent section. At the end of the garbage collector 9, the distance between the guide plates 96 and 97 is somewhat smaller than the width 94 of the run 58 of the conveyor 12. This is corresponding, for. B. to Figure 1 with its front deflection axis 52 below the rear deflection axis 21 of the garbage collector 9. The guide plates 96 and 97 are continued by parallel guide plates 66 and 66 'of the conveyor 12 up to its rear end. At this end the collecting container 6 is arranged with a width 102, whereby this width is greater than the width 94 of the upper run 58 of the conveyor 12.

To drive the waste pickup 9, a drive device 98 is arranged on one side on the rear deflection axis 21. At least the support rollers 25 and 26 are drive-connected to the deflection axis 21 by drive connections 99.

The conveyor 12 also has an output device 101 arranged on one side on its rear deflection axis 53.

Since the conveyor 12 is arranged between the wheels 14 and 14 'above the wheel axis 13, its width 94 is less than the inner distance between the two wheels.

In Figure 5, the feed rotor 11 is shown. The frame 84 is essentially U-shaped. A U-web 103 runs horizontally and parallel to the rotor pivot axis 120 or rotor rotation axis 18. At its ends, the U-web 103 has U-legs 104 and 105 arranged at right angles to this. These extend to almost above a rotor shaft 106 which is concentric with the axis of rotation 18. Bearing flanges 107 and 108 are arranged at the ends 109 and 110 of the U-legs 104 and 105. These are placed on the U-legs 104 and 105 from the outside and connected to them.

The axis of rotation 18 is mounted in the bearing flanges 107 and 108.

Concentric rotor end disks 132 and 133 are arranged on the axis of rotation 18. These limit the feed rotor 11 in the direction of the axis of rotation. A plurality of radially projecting tines 67 are arranged on the rotor shaft 106. For clarification, only a few tines are shown in FIG. 5.

Bearing devices 85 and 86 are arranged on the U-web 103 for mounting the feed rotor 11 on the swivel axis 120. These are each formed by a pair of bearing flanges 116, 117 and 118, 119. The bearing flanges have a corresponding opening to accommodate the swivel axis.

A drive device 111 is arranged on one side of the feed rotor 11. This comprises a motor 112 arranged above the U-web 103 and a drive pulley 113 mounted on its drive axle. This is connected via a V-belt 115 to a drive pulley 114 arranged coaxially on the axis of rotation.

FIG. 6 shows a side view, in particular of the flange stop 108. This is essentially U-shaped. In the U-webs 122 elongated holes 123 and 124 are arranged symmetrically to an elongated groove receiving the axis of rotation. A U-leg has a thickening in which a bore 30 is arranged. One end of the actuating device 29 can be stored in this bore.

A U-leg 105 of the frame 84 from FIG. 5 is visible above the bearing flange 108. Both the longitudinal groove 122 and the U-leg 105 extend vertically in the direction 125. At the upper end of the U-leg 105, the bearing flange 119 runs in the direction 126. This has at its free end a pivot bearing bore 121. Angle 127 is included between direction 125 of longitudinal groove 122 and direction 126 of bearing flange 119.

FIG. 7 shows the drive device of the feed rotor 11. The rotor end disk 133 is arranged concentrically to the axis of rotation 18. Tines 67 protrude radially from these and fix the circumferential line 129 when rotated in the direction 128.

The drive pulley 114 is connected to it coaxially with the axis of rotation 18. The drive pulley 113 connected to the motor is arranged vertically above this drive pulley. Both are connected to the drive via a V-belt 115. For tensioning the V-belt, a tensioning roller 131, which is offset laterally to the connecting line of these two, is arranged between the drive pulleys 113 and 114.

In Figure 8, the feed rotor is shown in a first operating position. The same reference numerals designate the same parts as are already known from the previous figures. This is only partially addressed.

The feed rotor 11 is pivoted forward about the pivot bearing axis 120 with the aid of the adjusting device 29. The deepest point of the feed rotor 11 is located near the surface 68 and in front of the receiving wedge strip 10. The tines 67 engage in a layer of waste 136 lying on the surface when rotated counterclockwise 128. Both by rotating the feed rotor 11 and by moving the vehicle in the direction 140, the waste 136 is conveyed onto the upper run 22 of the waste receiver via the receiving wedge strip 10. This transports the garbage in the direction of 137. In the operating position shown in FIG. 8, the receiving wedge strip 10 is arranged near the surface 68 but above it. The feed rotor 11 can be pivoted forwards with the aid of the adjusting device 29 until the length of the piston 138 corresponds approximately to the length of the adjusting device 29. In the position of the feed rotor pivoted furthest back, the piston 138 is completely retracted into the actuating device 29. The entire swivel range of the feed rotor corresponds essentially to the swivel arc 74 of the axis of rotation 18.

With the aid of the elongated holes 123 and 124 shown in FIG. 6, fine adjustment of the height of the axis of rotation 18 in directions 141 is possible.

A wedge-shaped recess 139 is arranged in a side wall 134 of the impact lining 15. This serves to receive the axis of rotation 18 when the feed rotor 11 is pivoted.

In the operating position shown in FIG. 8, the tines 67 do not engage in the sand 135 lying below the surface 68.

FIG. 9 shows a second operating position of the feed rotor 11. In this case, the receiving wedge ledge 144 is inserted into the sand 135 to the depth d. Both sand 135 and waste 136 are arranged between the receiving wedge strip 10 and the feed rotor 11. In this operating position, the feed rotor 11 is pivoted so far to the rear that the distance e between the circumferential line 129 and the wedge strip 10 is minimal. Other characteristic sizes according to the Invention are the distance a from the tip 144 of the receiving wedge strip 10 and the perpendicular base 143 of the solder 142 placed by the pivot axis 120, and the distance b and c of the pivot axis 120 from the vertical base and from the plane formed by the receiving wedge strip 10.

The receiving wedge strip forms an angle α with the horizontal which is larger by the angle 145 than the angle β enclosed between the upper strand 22 and the horizontal.

In Figure 10, the feed rotor 11 is shown in a third operating position. The piston 138 is fully inserted into the actuating device 29 and the feed rotor is arranged in its most pivoted rearward position. In this position, its peripheral line 129 almost touches the cover 16 from below and the axis of rotation 18 is inserted as far as possible into the cutout 139 of the side wall of the impact cladding.

In the third operating position, circumferential line 129 and upper run 22 are arranged at a distance f. The distance f is approximately twice the distance e between the circumferential line and the receiving wedge strip 10 in the second operating position. As can be seen from the envelope 163 of the circumferential line 129 during the pivoting, the distance e is the minimum distance.

FIG. 11 shows the wheel axle 13 in a front view. A bottom wall 146 of the loading area 5 runs horizontally and lies on the cross member 78 of the vehicle frame. This is laterally enclosed by long beams 75 and 76. The loading area 5 in Side walls 82 and 87 enclosing the vertical direction are arranged above the longitudinal beams 75, 76 and offset to the outside thereof.

Lifting cylinders 61 and 61 'are fastened to the longitudinal beams 75 and 76 by means of upper lifting device fastenings 152 and 153 lying laterally on them. The lifting cylinders are arranged directly below the longitudinal beams 75 and 76 and, like these, are arranged symmetrically to the central vertical axis 164 of the vehicle. The lifting pistons 61 and 61 'are fastened to the wheel axle 13 by means of holding parts 59 and 151 between the wheels 14 and 14' directly adjacent to them. Lower lifter mounts 149 and 150 are formed on each of the support members. The reciprocating pistons movable in the lifting cylinders are mounted on these. Above the lower lifting device fasteners 149 and 150, the ends of the lifting pistons 61 and 61 'are passed through lifting piston guides 147 and 148.

In Figure 12, the lifting device is shown in a side view. The upper lifting device mounting 153 is visible below the longitudinal beam 76. This is essentially formed by a profile arranged laterally on it parallel to the longitudinal beam 76. A hole 154 for supporting the upper end of the lifting cylinder 61 is formed in the center of this profile. Two support arms 62 and 63 pointing in the direction of the wheel axis are arranged on the longitudinal member 76 at the ends of the profile. A profile 148 for fixing the lower end of the lifting cylinder 61 is attached between the free ends of the support arms. The lifting cylinder 61 itself runs centrally to the support arms 62 and 63 which essentially enclose a triangle with the longitudinal beam 76. Below the In the illustration according to FIG. 12, the profile 148 is arranged directly at the lower bearing point of the lifting device. At the free ends of the support arms 62 and 63, the holding part 59 is shown abutting them. In cross section, this essentially has the shape of an isosceles triangle. The free ends of the support arms 62 and 63 abut the ends of the base line of this triangle. The lower bearing point 150 of the lifting device is arranged centrally between these free ends in the middle of the base line. The two legs of the triangle point in the direction of the wheel axis 13 and partially encompass them.

FIG. 13 shows the lifting device with the lifting piston 60 extended to the maximum. The same reference numerals designate the same parts as in FIG. This is only partially addressed.

The longitudinal member 76 is shown lifted upwards by the distance g with respect to the wheel axle 13. The free ends 157 and 158 of the support arms 62 and 63 have journals 155 and 156. These are arranged parallel to the lifting cylinder 61 or reciprocating piston 60 and point to the holding part 59. Corresponding bearing openings 159 and 160 are arranged in this, which in the illustration according to FIG. 12 are in engagement with the bearing pins 155 and 156.
