Definitions

  • the invention relates to a stabilizer or recycler which has a rotor housing, in which a milling / mixing rotor is arranged, and a unit for discharging soil stabilizer.
  • a pulverulent binder for example lime or cement
  • Typical applications for soil stabilization are the construction of roads or railway tracks as well as industrial areas.
  • the known stabilizer or recycler without binder spreader can basically be operated in the forward and backward direction.
  • Stabilizer or recycler which have a binder spreader, have only one working direction, since the binder is always to be discharged before the milling / mixing rotor. Therefore, the working direction of the stabilizer or reclaimer equipped with a binder spreader will be discussed below.
  • the known stabilizer or recycler have a chassis that carries a machine frame.
  • the chassis has front and rear wheels in the working direction, between which the rotor housing is arranged, which receives the milling / mixing rotor.

  • These include, for example, hydraulic pumps for the operation of hydraulic motors, with which the wheels of the self-propelled construction machine are driven.
  • the unit for discharging the binder of the known stabilizer or recycler has a reservoir for the binder and a metering device for metering the binder.
  • Stabilizer or recycler are known in which the metering device has one or more rotary valves.
  • the known recycler or stabilizer are characterized in that the rotor housing is arranged with the milling / mixing rotor on the machine frame between the front or rear wheels, wherein the binder is discharged in the working direction in front of the milling / mixing rotor.

  • the funnel-shaped reservoir for the binder has a lower portion disposed between the front wheels and the milling and mixing rotor and an upper portion located above the milling and mixing rotor.
  • the rotary feeder for metering the binder is arranged.
  • the problem arises of accommodating in or on the machine frame the drive unit for the construction machine on the one hand and the binder for the binder on the other hand. Not only the limited spatial dimensions of the construction machine play a role, but also the weight of the drive unit and the reservoir. Since the reservoir filled with binder has a relatively high weight, the weight distribution of the construction machine is substantially determined by the arrangement of the reservoir on the machine frame.
  • the problem of accurate dosage since the desired spread rate is to be maintained regardless of the speed of the construction machine exactly.
  • the rotating cellular wheel transports the binder to a failure opening from which the binder falls down under the influence of gravity.
  • the flow rate of the binder is dependent on the chamber volume, the degree of filling and the speed of the rotary valve of the metering.
  • a high volumetric dosing accuracy requires that the bulk density is always constant, so that the cell wheel is always supplied with the same degree of filling.
  • the FR 2 743 372 describes an off-road construction machine having a means for spreading.
  • the spreading means is provided in a silo which communicates with a hopper of a means for spreading the spreading means.

  • the spreader has an extraction device in the form of a screw conveyor, with which the binder is conveyed to a hopper to deploy the binder via a distributor rotor at the rear end of the trailer can. It is not apparent to what extent the center of gravity of the elongated reservoir should be arranged in the working direction behind the axis of rotation of a milling / mixing rotor.

  • the solution of this object is achieved according to the invention with the features of claim 1.
  • Advantageous embodiments of the invention are the subject of the dependent claims:
  • the entire reservoir is located in the working direction behind the milling / mixing rotor. But at least the part of the reservoir should be located behind the milling / mixing rotor, which has the larger volume. In this case, a part of the reservoir can be arranged above the milling / mixing rotor.
  • the center of gravity of the storage container is arranged in the working direction behind the axis of rotation of the milling / mixing rotor.
  • the drive unit of the construction machine is arranged in front of the milling / mixing rotor.
  • the drive unit can be arranged behind a control stand arranged at the front end of the construction machine or in front of a control station arranged in the middle of the machine.
  • the drive unit can be arranged behind a control stand arranged at the front end of the construction machine or in front of a control station arranged in the middle of the machine.
  • the area of the machine frame behind the milling / mixing rotor which is generally shorter than the area in front of the milling / mixing rotor, still provides sufficient space for the arrangement of the reservoir available.
  • the reservoir which is filled with binder, has a higher weight than the drive unit, resulting from the length ratios of the machine part in front of and behind the milling / mixing rotor optimum weight distribution.
  • the focus of the construction machine is in such an arrangement of reservoir and drive unit between the front and rear wheels in the milling / mixing rotor, which is the goal in practice.
  • the binder is still discharged in front of the milling / mixing rotor. Therefore, the device for the exit of the binder in the working direction in front of the milling / mixing rotor is arranged. In this case, the binder can also be discharged into the rotor housing.
  • This device may be a device commonly used in known stabilizers or recyclers.
  • the binder can escape from a funnel-shaped hood, which is equipped with a dust protection device.
  • a preferred embodiment of the invention provides that the reservoir has an outlet which is provided at a front in the working direction portion of the reservoir. If the reservoir is funnel-shaped, the outlet should be located at an upper portion of the reservoir.
  • the metering device for metering the binder can be arranged directly below the outlet of the storage container. Since the column of binder present above an outlet at the upper portion of the binder-filled reservoir is smaller overall than the column above an outlet at the lower portion of the reservoir, there are less variations in the density of the binder with which the metering device is charged , Dosing inaccuracies leading to fluctuations in the density of the binder are therefore largely excluded.
  • the unit for discharging binder preferably has a conveying device with which the binder can also be conveyed from the lower part section to the upper part section of a funnel-shaped storage container.
  • the conveyor for conveying binder may be formed differently.
  • the conveyor has at least one scraper belt, which has chains or belts driven to convey the binder.

  • the conveying device for example the scraper belt or the screw conveyor, is at least partially within the conveyor belt Reservoir arranged so that conveyor and container form a common assembly.
  • the storage container is preferably designed as a funnel-shaped container, so that the binder can collect and be taken up at the bottom of the container.
  • the reservoir may have a bottom which is formed by diagonally converging housing parts which extend over a part or the entire working width of the machine. But it can also parts of the side walls taper towards each other. In principle, it is also possible that the reservoir has a flat bottom.
  • the reservoir has a front in the working direction portion which is located above the milling / mixing rotor, and having a working rear portion, which is located above the rear wheels or drives, while located between the milling - / mixing rotor and the rear wheels or drives a central portion extends.
  • the rear portion of the reservoir may terminate in front of the axis of the rear wheels or may extend beyond the axis of the rear wheels.
  • the middle section of the reservoir preferably comprises a relatively low-lying lower section in which the binder can collect. Consequently, the container has the greatest depth in the area between the milling / mixing rotor and the rear wheels or drives, so that the center of gravity of the reservoir is approximately in this area.
  • the unit for discharging binder has a transport device in order to transport the binder leaving the metering device to the device on which the metered binder is present emerges from the milling / mixing rotor.
  • the binder is carried by gravity.
  • the transport device may be a chute.
  • An alternative embodiment provides that the metering device is not arranged directly below the outlet of the reservoir, but on the means for the exit of the binder.
  • This embodiment has the advantage that the distance which the binder has to cover after the metering is relatively small, so that a particularly high metering accuracy can be achieved.
  • the metering device for metering the binder preferably has at least one rotary valve. It can also be provided several, for example, three rotary valves, which are arranged over the entire working width of the construction machine in the longitudinal direction of the rotary valves one behind the other. In this case, individual rotary valves can also be arranged offset to one another in the longitudinal direction of the recycler or stabilizer. All rotary valves should be individually switchable. However, in principle it is also possible for the binder to be metered with other agents known from the prior art than with one or more rotary valves.
  • a device for distributing the binder is provided in a direction transverse to the longitudinal direction of the machine frame direction.
  • the means for distributing the binder is a distributor screw arranged transversely to the machine frame.
  • a plurality of distributor screws it is also possible for a plurality of distributor screws to be arranged one behind the other in the longitudinal direction of the distributor screws. In this case, individual distributor screws can also be arranged offset to one another in the longitudinal direction of the recycler or stabilizer.
  • the reservoir for binder has a relatively large volume, resulting in relatively large dimensions in height and / or width, a special permit may be required for driving and / or transporting the construction machine on public roads. Therefore, it is desirable that the overall height and width of the reservoir is as small as possible, but this limits the use of the construction machine.
  • the reservoir is formed as a container whose volume is variable.
  • the container can be scaled down to the size that does not yet require a transport permit. As a result, the transport height and / or transport width of the machine can be reduced.
  • the container consists of an upper and lower housing part, which can be moved against each other.
  • the connection of the lower and upper housing part may be formed, for example, in the manner of a telescope.

  • the upper and lower housing parts are connected to one another via a bellows, which is pulled apart or pulled together like an accordion to increase or reduce the volume.

Also, at least parts of the front and rear walls of the reservoir may be parts of the machine frame.
  • the upper housing part and / or the lower housing part of the reservoir can be designed as parts which can be mounted on the machine frame, so that the reservoir can be subsequently created on the existing machine frame solely by mounting the housing upper or lower part. Since parts of the reservoir are already parts of the machine frame, relatively few parts are needed to mount the reservoir.
