Definitions

  • the invention is about a soil compactor of cylindrical drum type, suitable in particular to be used to perform compaction, levelling and flattening works on surfaces with limited extension.
  • the vibrating plates of known type are carried out with different size according to the extension of the surface to be worked, but they all essentially consist of a frame provided with a handling drawbar, supporting a plane surface plate which is put in contact with the surface to be compacted.
  • the plate is connected to a thermal engine by means of a shaft with eccentric masses which, by rotating, makes the plate to vibrate obtaining the soil compaction.
  • the inertia that the vibration gives to the plate also causes at the same time the advancement of the whole compactor, guided by the operator in the desired direction by manoeuvring the shaft.
  • a first inconvenience is due to the fact that they are not provided with steering devices so that, to change the advancement direction and/or sense when they arrive at the limit of the working area or at a corner, the operator manually acts on the drawbar, causing the plate to graze the finished surface.
  • the levelling operation of surfaces covered with tiles or bricks could involve the breaking of said tiles or said bricks, especially if the underlying soil is stony.
  • small size roller compactors which, being provided with steering wheels and roller rotation devices, makes easier the flattening and compaction operation, are used instead of the vibrating plates.
  • roller compactors move back and forth on the surface to be worked by rollers rotation, independently from the fact that vibrating devices are applied on them or not.
  • roller compactors can thus compact the ground with or without making use of vibrations, reducing the breaking risk when surfaces covered with bricks or tiles leaning on stony soils are compacted and flattened.
  • roller compactors have the inconvenience to be pollutant for the environment in which they operate, since they are activated by thermal engines of the same kind of those used for vibrating plates.
  • the activation with a thermal engine also involves the need to provide for at least a speed gear, a brake, a clutch and connection joints to put in rotation the rollers and move forward the compactor.
  • the present invention intends to overcome the aforesaid inconveniences and limitations.
  • roller compactor which is less pollutant for the environment in which operates with respect to roller compactors of known type.
  • roller compactor of the invention has lower productive costs with respect to equivalent roller compactors of known type.
  • roller compactor of the invention has lower size, weights and overall dimensions with respect to the roller compactors available on the market.
  • the compactor of the invention has comparable size and weights with those of the vibrating plates.
  • a soil roller compactor which, according to the main claim, comprises:
  • the compactor comprises a single rear roller and a pair of front rollers, coaxially disposed side by side.
  • the rear roller receives from the driving group:
  • the vibration and the rotation are generated by mutually independent electric motors, so that the roller vibration and rotation can be mutually independent or concurrent according to the choice of the operator who manoeuvres the control means.
  • the steering means comprise a steering group interposed between the front rollers and a push and/or traction structure connected to the frame and provided with a handle to which control push buttons manoeuvrable by the operator are fixed.
  • the steering means also comprise a remote control.
  • roller compactor of the invention being activated by electric motors, is less pollutant with respect to both the vibrating plates and the known roller compactors activated by thermal engines.
  • the elimination of the fuel tank allows to reduce weights and overall dimensions.
  • the soil compactor of the invention is shown in Figures 1 to 4, where it is generally indicated with numeral 1.
  • a driving group generally indicated with numeral 6 and shown in detail in Figures 5 to 9, forces the rotation and the vibration of the rear cylinder 5, while a steering group, generally indicated with numeral 7 and particularly visible in greater detail in Figure 9, allows the steering of the front cylindrical rollers 3, 4.
  • the driving group 6 comprises one or more electric motors, mechanically coupled with at least one of said rollers and electrically connected to electric feeding means.
  • the driving group 6 comprises a traction electric motor 8 and a vibration electric motor 9, which are both connected to the rear cylindrical roller 5.
  • roller 5 in the executive embodiment described hereby there is a single rear roller 5 , but in different executive embodiments, similarly to the aforementioned front rollers 3, 4, said roller can be formed by one or more mutually coaxial rollers disposed side by side.
  • the rear cylindrical roller 5, the traction electric motor 8 and the vibration electric motor 9 are supported by a single counter-frame 10 provided with elastic means 11, which are housed inside holes 2a of the frame 2, as one can see in Figures 1 to 4, to provide for a dampened connection between the frame 2 and the counter-frame 10 .
  • the rear cylindrical roller 5 is supported by a rear rotation shaft, generally indicated with numeral 12, which defines the rear longitudinal rotation axis X of the rear cylindrical roller 5.
  • the rotation shaft 12 is composed by a traction half-shaft 13 mechanically connected to the traction electric motor 8 and by a vibration half-shaft 14, coaxial with the traction half-shaft 13, mechanically connected to the vibration electric motor 9.
  • the traction electric motor 8 is mechanically connected to the traction half shaft 13 by the interposition of a traction kinematic group, generally indicated with numeral 15, which comprises a speed reducer 16 having the inlet shaft 17 coupled with the shaft of the traction motor 8 and the outlet shaft 18 provided with a first toothed pinion 19 which engages with a chain 20 wound as a loop ring on a second pinion 21 coaxial with the traction half-shaft 13.
  • a traction kinematic group generally indicated with numeral 15, which comprises a speed reducer 16 having the inlet shaft 17 coupled with the shaft of the traction motor 8 and the outlet shaft 18 provided with a first toothed pinion 19 which engages with a chain 20 wound as a loop ring on a second pinion 21 coaxial with the traction half-shaft 13.
  • the latter is also provided with a coupling flange 22 to the rear drum 5.
  • the vibration electric motor 9 is mechanically connected to the vibration half-shaft 14 by means of a vibration kinematic group, generally indicated with numeral 23, comprising a first toothed pulley 24 coupled with the shaft of the vibration motor 9, which engages with a toothed belt 25 wound as a loop ring on a second toothed pulley 26 coaxial with the vibration half-shaft 14 that externally comprises an eccentric mass 27.
  • a vibration kinematic group generally indicated with numeral 23
  • a first toothed pulley 24 coupled with the shaft of the vibration motor 9, which engages with a toothed belt 25 wound as a loop ring on a second toothed pulley 26 coaxial with the vibration half-shaft 14 that externally comprises an eccentric mass 27.
  • the kinematic mechanism could provide for the utilization of chains and pinions, and the rotation transmission could similarly provide for the utilization of pulleys and toothed belts.
  • the steering group generally indicated with numeral 7, it comprises a steering electric motor 28 coupled with a steering kinematic mechanism, generally indicated with numeral 29, which is mechanically connected to the pair of front cylindrical rollers 3, 4.
  • the steering kinematic mechanism 29 and the steering electric motor 28 are both supported by a plate 30 which is connected to the frame 2 through fastening means.
  • the steering kinematic mechanism 29 comprises a speed reducer 31 having the inlet shaft 32 coupled with the shaft of said steering electric motor 28, and the outlet shaft 33 provided with a pinion 34 which, by means of a chain not shown in the drawings for sake of simplicity, engages with a crown gear 35, coaxially to which a fork 36 is disposed.
  • the end of the fork 36 supports a sleeve 37, to which the front rotation shaft 38 which supports the front cylinders 3, 4, defining their front longitudinal rotation axis Y, is centrally connected.
