Definitions

  • 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.
  • 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.
  • 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.
  • the known feed rotor must frequently be cleaned and freed from the algae.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the feed rotor 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.
  • the second operating position of the feed rotor is preferably used.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the adjusting device is arranged on the side of the frame.
  • 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.
  • the rotor is thus easily accessible.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • tipping devices for a loading area arranged on the vehicle frame can also be mounted at these ends.
  • 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.
  • 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.
  • 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.
