Definitions

  • the invention relates to a device for compacting waste, in particular cardboard boxes or the like, by means of a reciprocating driven compacting roller.
  • the compaction roller is mounted in a chassis which is to be pulled over a garbage dump by means of a towing vehicle in order to compress the garbage present there (US Pat. No. 3,718,170).
  • compaction rollers of this type can form parts of the vehicle itself.
  • the invention has for its object to design a device of the type mentioned so that it can serve with a robust and failure-prone construction for compacting rubbish brought into open-topped containers.
  • the compacting roller is mounted on the free end of a pivot arm pivotally mounted on a stand, the projecting length of which can be varied, the pivot arm projecting into a container which is open at the top.
  • the roller can consist of a hollow cylinder, which is closed at its two end faces, the material of the roller can be steel sheet, so that with a diameter of about 80 cm, depending on the sheet thickness, a weight in the order of about 200 kg to 300 kg results. It is therefore sufficient if the driven roller lies with its own weight on the garbage to be compressed. An additional pressure to be exerted on the roller is therefore not necessary.
  • the drive of the roller is located in the interior thereof, since in this way the roller weight is further increased by the drive motor and an additionally provided gear.
  • the drive can expediently have a spur gear, which is arranged together with the drive motor in a central section of the roller which is fixedly attached to the free end of the swivel arm.
  • Two outer rotatably mounted hollow sections of the roller adjoin the middle section.
  • the drive motor is expediently arranged eccentrically to a continuous shaft which is acted upon by the spur gear, the drive motor protruding laterally next to the shaft into one of the two hollow sections.
  • the drive of the roller can expediently be designed such that the roller makes about 25 revolutions / minute if it has a diameter of about 80 cm.
  • the central stationary section of the roller can be formed by the gear housing or a cover of the gear housing, which at the same time forms the bearing for the two rotatable hollow sections of the roller or for the shaft thereof.
  • the change in length of the swivel arm is brought about by the fact that the swivel arm consists of individual sections which can be telescopically pushed into one another. In this way, the distance of the axis of the roller to the upper bearing of the swivel arm changes during the horizontal movement over the compressing garbage by pushing the individual telescopic sections into one another, the swivel arm taking up its smallest length when it passes the stand carrying it .
  • the stand for the mounting of the swivel arm is provided with a hydraulic lifting device which allows the bearing point for the upper end of the swivel arm to be moved up and down. This makes it possible to compensate for the stack height within the container in that, depending on the amount of garbage already in the container, the storage point of the swivel arm is guided more or less upwards.
  • the length of the swivel arm from its upper bearing point to its lower free end plus half the roller diameter is somewhat less than half the length of the container. In this way, the roller cannot run against the container wall even when the swivel arm is in the respective end positions at a very acute angle to the horizontal.
  • the hydraulic lifting device in the stand of the device according to the invention also serves the removal and insertion of the roller into the container, for which purpose a section of the swivel arm projecting beyond the roller beyond the bearing point on the stand can be provided, which in the pivoted-out position of the swivel arm by means of a linkage, a chain or the like with its bearing point opposite end can be articulated to the stand. If this articulated connection is made, then raising the bearing point leads to the pivot arm being pivoted upward out of the container, while, conversely, it can be lowered very quickly into the container by lowering the bearing point. Due to the length of the swivel arm, the stroke of the hydraulic device when the swivel arm is swung out is increased by the different lever arm lengths.
  • the swivel arm is designed telescopically, it can be particularly advantageous if the last hollow telescopic section forms the arm protruding beyond the bearing point on which the linkage or the chain engages.
  • the stand is in the center of the container and overlaps it with an arm, at the free end of which the bearing point for the swivel arm is arranged. So that the stand stands securely and firmly during the compaction movement, it is advantageous if it is provided with a larger base plate which engages under the container and on which the container stands. In this way, the stand is securely held by the weight of the container.
  • interlocking catches or the like can be provided as connecting means between the base plate and the container.
  • the base plate in particular can be designed such that it is provided on one end face with a stop rail which overlaps the corresponding end face of the container from below, against which the container is brought into contact with an obliquely downward displacement movement and in the state of use is present.
  • the base plate, stand and container are always arranged so that the stand is in the center of the container.
  • the container can be removed in the opposite direction from this base plate designed in this way with an obliquely upward lifting movement, the roller advantageously lying on the side facing away from the crane or another lifting device of the container, so that it does not collide with the wall when the container is lifted out .
  • the drive motor of the roller is expediently designed as a reversible motor, so that the roller moves back over the waste by switching over in the end positions.
  • This changeover can be controlled by hand or also by limit switches, which take effect in the respective end positions.
  • These limit switches can be actuated by the swivel arm or by stops arranged on the swivel arm, provided that the swivel arm in each case carries out the same deflection movement, which presupposes that the lifting device on the stand for the individual successive reciprocating movements of the swivel arm each by a certain amount the bearing point for raises the swivel arm.
  • This lifting can take place in a particularly advantageous manner in that when the swivel arm is pushed together it moves against a stop and in the floating position of the hydraulic device the piston rod, which bears the bearing point for the swivel arm, moves upward.
  • a check valve is switched on, which holds the hydraulic oil thus displaced on the piston rod side in the position brought about by this, the piston or the piston rod of the hydraulic device remains in this position, so that the bearing point for the swivel arm moves upwards automatically. This does not affect the compaction of the garbage in the container, since the roller can continue to press freely on the garbage in the container due to its own weight.
  • This check valve can in turn be used to lower the hydraulic device again when the raised device is to be inserted into a container to be refilled.
  • the hydraulic device can be actuated from the outside, but this is essentially only necessary when the container is changed. This operation is therefore not carried out by the person who fills the container, but by the person who delivers and picks up the container.
  • the surface of the roller is roughened and / or provided with studs or the like which run transversely to the direction of movement of the roller and which are therefore longitudinal extend to the roller.
  • This can be flat iron or the like, which ends about 15 mm above the roller surface, so that they do not penetrate too deeply into the material to be compacted and do not tear it too much.
  • a cable drum at the upper free end of the telescopically collapsible swivel arm, as is used in other construction machines or the like, in which cables have to be continuously lengthened and shortened.
  • At least one ring is arranged in the region of the front ends of the roller encompasses the roller in a ring and the upper edge of which lies above the roller surface. In this way it is achieved that the rim presses into the material in the vicinity of the wall area of the container and thus practically limits the pressing area of the roller, so that there is no great tension of the material with the inner wall surface in the immediate wall area of the container .
  • the two end faces of the roller are provided with outwardly curved walls or lids, which again center the roller abutting the container wall lead there.
  • the embodiment described above is particularly suitable for large containers, since it requires a certain amount of construction and space.
  • an embodiment can be used economically, in which the swivel arm is provided with at least one articulated joint dividing the swivel arm, in the area of which at least one stop is provided which prevents the swivel arm from being fully stretched, so that the two adjoining the articulated joint Include sections of the swivel arm in the extended position of the roller at an angle of less than 180 °.
  • a particularly simple construction for the articulated joint is obtained if one part of the articulated joint is designed as a fork, between which the other joint part engages, with a bolt passing through both parts holding it together.
  • the stop can be formed in a particularly advantageous manner by a further pin lying outside the hinge pin and penetrating through an outer fork section.
  • a swivel arm of the type described can also be used in the arrangement described above, in which the swivel arm, with an increasingly shorter length, passes in a pendulum-like manner on the stand placed in the center of the container.
  • Such an application requires, however, that the bearing point for the swivel arm is at least as high above the last layer of garbage in the container or above its upper edge as it corresponds to a section length of the swivel arm, so that during the movement of the swivel arm at which the apex of the angle between the sections below, the sections in the joint area cannot drill into the garbage, but rather the joint is guided over the garbage. This would require a relatively high stand and thus a larger and heavier construction.
  • the swivel arm can only be moved on one side of the stand and if the apex of the angle formed between the sections of the swivel arm lies at the top in this movement range.
  • the width of the roller must be less than or equal to the width of the garbage to be driven over, it is particularly advantageous here if the stand is arranged on a narrow side of the container, because the width of the roller can be less than or approximately equal to the inner width of the container . In this way, the roller itself can be kept relatively narrow, so that it can be produced inexpensively. However, it then has to travel a longer way than if, conversely, the stand stood on a broad side of the container.
  • the specific surface pressure exerted on the garbage by means of the roller is, however, just as great in the narrower and far less expensive roller as in the other design.
  • a particularly advantageous embodiment results when the swivel arm is divided into a total of three sections, between which two articulated joints are provided.
  • the buckling of the individual sections and thus the movement of the articulated joints can be followed Keep relatively small at the top, so that there is not too great a height for inserting the roller into the container, i.e. for swinging over or pushing over the edge of the container.
  • first section of the swivel arm adjoining the bearing point on the stand is approximately vertical in order to lift or insert the roller, the second section adjoining this section at right angles and the third section at the end pointing downward at right angles the roller, which has the drive inside, hangs.

  • the pitch circle roller ensures that the force acts on the same lever arm on the first lever in every pivoting position of the first section.
  • the lifting device for the vertical alignment of the first section of the swivel arm can advantageously consist of a rack and pinion winch, the housing of which is articulated to the stand in the lower region of the stand.

  • the pitch circle roller itself is fixed to the first section of the swivel arm and is moved together with it.
  • the height of the stand can be changed.
  • the stand itself consists of two sections which are longitudinally displaceable with respect to one another and which preferably interlock telescopically and can be fixed in different relative positions to one another.

  • this embodiment offers the advantageous possibility of using the lifting device described, in particular in its design as a rack and pinion winch, for raising and lowering the movable upper section of the stand.
  • an articulated connection is provided on the upper movable section of the stand, to which the upper end of the rack can optionally be connected.
  • This hinge connection can consist of a simple hinge pin which, on the one hand, passes through the upper end of the rack and, on the other hand, a tab or the like, which is fastened to the upper movable section of the stand.
  • connection to the rack end can expediently consist of a shackle.
  • a lock is provided between the first section of the swivel arm and the upper section of the stand in the region of the bearing point of the swivel arm in a vertical orientation to one another, so that the swivel arm does not fold down when the pull cable is released.
