Definitions

  • the invention relates to a groupage container which can be attached in particular to vehicles, trailers or the like, according to the first part of patent claim 1.
  • a mechanically driven boom is connected to a nozzle.
  • the boom cannot be positioned via a remote control, so that the nozzle can pick up waste in front of an associated carrier vehicle or on its side.
  • the boom with the nozzle can be moved back into a position in which the driver is given an unobstructed view of the road.
  • the boom nozzle arrangement can also be moved into a position to the side of the carrier vehicle, so that it is possible to pass underpasses, below trees, etc.
  • a known mowing device (cf. the European patent published under No. 0 016 440) has a container of the type mentioned in the introduction in which a fan and its drive device are accommodated. This acts on an inlet port breaking through the container wall, to which a flexible pipeline is connected via a telescopically resilient quick-release fastener. The pipeline leads to a suction box, which collects groupage and blows into the container via the blower. If waste such as this is to be used to collect waste that is widely scattered from one another in the container or to empty waste baskets, in addition to one person to operate the vehicle, at least one other person is required who brings the flexible pipeline with suction box into appropriate positions for picking up the waste pieces.
  • a known boom for the suction hose of street sweepers (DE-A-20 52 160) can be pivoted about a standing axis and can be raised and lowered. It is composed of a lower flange carrying the suction hose and an upper flange, which are made up of at least three angle levers articulated to one another or an articulated chain.
  • suction hoses with a large diameter for example of the order of magnitude of 300 mm, they should be kept within the vehicle profile during the transport journey when the boom is swung in around the standing axle journal with the tightest curvature in front of the rear bulkhead.
  • a suction device for suctioning organic waste is known (DE-A 30 42 510), the suction head of which can be tilted around a horizontal axis lying in the direction of travel Boom sits, with a proboscis movable with the boom being provided.
  • a working shaft with an axis position parallel to the floor, which is equipped with flexible rods protruding radially beyond the side suction housing walls up to approximately contact with the floor to loosen the material to be extracted.
  • the working shaft accommodated in this way leads to a considerable diameter of the suction intake opening.
  • a remotely pivotable suction nozzle is provided, which has a connecting part at its end for the attachment of a suction mower head.
  • a connection cover in the mouth of the proboscis instead of the suction mowing head.
  • This cover has a smaller opening for connecting an additional flexible suction hose. So that bulky groupage such as bottles, cans, etc. can reach the downstream suction nozzle through the suction hose, it is proposed to provide the diameter of the suction hose with a correspondingly sufficient cross section.
  • the flexible suction hoses have handles on their free ends serving as suction mouths for grasping by an operator.
  • the suction hoses are supported on support rods with swivel bearings by a support which sits on the end cover of the downstream suction nozzle.
  • the arrangement is such that the suction mouth of the suction hose is just above of the street side space to be cleaned depends and can be lowered into the suction position by the operator with slight effort.
  • the object underlying the invention is therefore to improve generic groupage containers in such a way that a single operator is able to collect widely scattered waste of any dimensions efficiently and precisely; in particular, clogging and blocking of the pipeline due to bulky waste on the one hand and a large pipe diameter for the suction arm and the associated pressure losses on the other hand should be avoided.
  • a groupage container characterized in claim 1 is proposed. This allows the pipe diameter to be kept sufficiently small; Larger pipe diameters would lead to a disproportionate effort in the design and strength of the suction fan due to the resulting pressure losses.
  • the invention in suction mode enables that, above all, the feed opening of the pipeline can be precisely aligned with the object to be collected, so that it is reliably grasped by the suction flow and transported away.
  • a suction nozzle is created, by means of which even very small groupage can be reliably detected.
  • the invention takes advantage of the fact that garbage containers, groupage containers u. Like. Can be easily applied to a motor vehicle or a trailer, so that in the sense of the invention the driver by actuating one or more actuators, preferably from the driver's seat, the at least partially flexible pipe to the individual, scattered waste parts can position. Positioning by actuating the actuators can be supplemented by driving the vehicle forward, backward, left and right. With the measure according to the invention, on the one hand stiffening the flexible pipeline and on the other hand largely maintaining its articulation, it is developed into an articulated suction arm, which can be placed more precisely to a waste part with increasing number of articulation points and / or the actuators.
  • a special realization of this inventive idea consists in providing a pivot linkage holding the pipeline with one or more articulated lever sections, each of which can be pivoted by at least one actuator supported against the container, the vehicle and / or an adjacent lever section.
  • the pivot linkage formed in this way from a plurality of individual, articulated lever arms can be positioned with great flexibility.
  • a particularly simple construction of the swivel linkage, which is suitable for realizing a suction arm that can be widely cantilevered from the container side wall, is that it is formed from a plurality of rod-shaped lever sections arranged one behind the other in the manner of a chain link, the first of which on the container, and the subsequent ones on the container opposite end of the previous lever section are articulated.
  • the pipeline has stiffened sections corresponding to the lever sections within the scope of the invention; it is sufficient if at least in the area of the joints of the Swivel linkage, the pipeline is flexible and flexible.
  • the provision of stiffened pipe sections can advantageously reduce the number of mounting elements which are necessary for fastening the pipe to the swivel linkage.
  • a further embodiment of the invention is adapted to the creation of the abovementioned cantilevered suction arm, according to which flexible and rigid pipe sections are arranged one behind the other along the course of the pipeline.
  • a suction element is created for the groupage container, which combines mechanical stability and strength on the one hand and high flexibility and mobility on the other and is therefore particularly suitable for exact positioning.
  • This suction element is essentially based on the elongated swivel linkage formed from successively articulated lever sections, the pipeline attached to it, running parallel thereto, and the adjusting elements for articulated movement.
  • the generic groupage containers are advantageously built so that they easily on vehicles, trailers and. Like. Are attachable.
  • the suction arm according to the invention is expediently fastened to a side wall of the container - corresponding to the long side of the vehicle.
  • the suction arm or the swivel linkage on the container and / or vehicle by at least one horizontal and at least one vertical axis are pivoted.
  • a special embodiment of the invention which enables sufficiently high positioning accuracy with moderate manufacturing and construction expenditure, consists in the fact that the Pivotal linkage has a first lever arm articulated on the container or vehicle and a second lever arm articulated on its end facing away from it, to which the stiffened pipe end is articulated, and that each pivot axis - including the horizontal and vertical pivot axes with respect to the articulation points located on the vehicle container - an actuator is assigned, which swivels the articulated parts - including the vehicle or container / lever rod - relative to each other.
  • the driver can extend the suction arm swiveled towards the container side wall behind the steering wheel by actuating the actuator, which is assigned to the suction arm articulation point on the container wall for realizing the vertical pivot axis, into the cantilevered operating position, for example.
  • the actuators e.g., electrically, hydraulically or pneumatically. It is particularly advantageous to design the actuators as pneumatic actuating cylinders, the ends of which each engage one of two adjacent suction arm sections which are connected to one another in an articulated manner.
  • the advantage of the pneumatic implementation is that compressed air can be used as the control and drive medium, which has a relatively low weight. Pneumatic linear drives therefore result in a lightweight construction;
  • the pneumatic actuating cylinders are characterized by their quick response and sufficient positioning accuracy.
  • At least one or more spring elements are assigned to each of the particularly loaded actuating cylinders, the points of engagement of which correspond to those of the actuating cylinder. M. a. W., the spring elements are connected in effect to the movements of the actuators in parallel.
  • a further development of the invention provides an operating device which can be positioned relative to the container wall and with which the individual actuators can be actuated .
  • the operating device has actuating levers which are each assigned to an actuator and can be positioned in positions for retracting, extending and stopping the individual actuators.
  • the comminution tool is articulated on the section forming the feed opening of the suction arm in such a way that this tool can be pivoted about 90 ° in front of the feed opening, the axis of rotation of which runs obliquely to the feed direction and / or is radially offset from the central longitudinal axis of the suction arm opening section .
  • a preferred drive for the comminution, in particular cutting, tool is an electric motor, with which high speeds can be achieved, which are advantageous for the effortless comminution of bulky or mechanically solid waste pieces.
  • a separate actuator is provided for pivoting the shredding tool into the area in front of the feed opening, which actuator can optionally be actuated from the steering wheel seat of the vehicle using the operating device. It is important to have an asymmetrical arrangement of the shredding tool with its axis of rotation with respect to the opening diameter of the suction intake, so that the risk of entangled pieces of waste getting tangled around the cutting or shredding tool is largely avoided.
  • the waste to be collected is primarily on the surface of the soil. To remove it, when operating the suction arm, make sure that it is on the one hand not too far away from the floor surface and on the other hand that it is not too close to the floor surface and is even "stuck" there.
  • This problem is addressed by a further embodiment of the invention, according to which at least one spacer wheel is attached to the outer wall of the suction arm in the region of its feed opening, said spacer wheel projecting beyond the edge of the feed nozzle with its fastening element.
  • the distance wheel is adjustable in terms of its distance from the opening edge of the feed nozzle, the operator can control the distance of the feed opening of the suction arm depending on the weight of the waste material to be sucked in.
  • Another (possibly pneumatic) actuating cylinder can be used to implement this (height) adjustability.
  • a container 1 is placed on the rear part of a commercial vehicle 2. From the interior of the container 1 leads out a connecting piece 3, to which a pipe 4 connects for sucking in groupage.
  • the pipe 4 is composed of a plurality of individual sections, namely three flexible pipe sections 5a, 5b, 5c and three stiffened pipe sections 6a, 6b, 6c.
  • the flexible and stiffened pipe sections are arranged alternately one behind the other, the pipe connecting to the connecting piece 3 with a flexible pipe section 5a and ending in the region of its intake opening with a stiffened pipe section 6c with the intake opening 7.
