Definitions

  • the present invention relates to an earth moving machine of the type with a chassis on which at least working means are mounted (such as arms, articulated or not articulated, supporting loading shovels, buckets or other means), forward movement means for moving the machine on the ground (such as engine-driven tracks or wheels) and a control position (which may or may not be enclosed in a cab).
  • working means such as arms, articulated or not articulated, supporting loading shovels, buckets or other means
  • forward movement means for moving the machine on the ground such as engine-driven tracks or wheels
  • a control position which may or may not be enclosed in a cab.
  • the control position usually comprises a seat for the operator connected to the earth moving machine chassis by means of a cushioned supporting element.
  • the operator sitting on the seat has access to earth moving machine driving means operatively connected to the forward movement means, as well as having access to means for operating the working means.
  • the present invention relates both to machines equipped with a single working device such as excavators, scrapers, etc., and to machines equipped with more than one working device, such as backhoe loaders.
  • the seat Whilst in machines equipped with a single working device the operating means are positioned close to the driving means to allow use of the device during earth moving machine movements, in machines equipped with more than one working device the seat can rotate between various operating positions in which the operator can access different operating means associated with the various working devices. In particular, in the case of the backhoe loader, the seat can rotate between a front position in which the operator can use first operating means connected to the front loading shovel arm, and a rear position in which the operator can use second operating means connected to the rear articulated arm.
  • the operating means usually comprise both control elements (such as controllers, push-buttons, etc.) and check elements (such as warning lights, screens, level indicators, etc.).
  • control elements such as controllers, push-buttons, etc.
  • check elements such as warning lights, screens, level indicators, etc.
  • the various components of the operating means are mounted differently in the control position.

  • control console 14 shock absorber 17 advantageously consists of the seat 11 supporting element 10, so that it cushions the control console 14 and the seat 11 together.
  • the shock absorber 17 may be separate from the supporting element 10.
  • control console 14 can move, relative to the seat 11, at least between an operating position in which it is close to the seat 11 ( Figures 1 and 3) allowing the operator to use the operating means 13, and a non-operating position in which it is distanced from the seat 11 ( Figures 2 and 4) so that it does not interfere with operator movements.
  • control console 14 moves between the operating position and the non-operating position by means of translation, and in particular, in Figures 1 and 2, by means of translation along a direction of movement substantially coinciding with a direction of longitudinal extension of the earth moving machine 2, and in Figures 3 and 4 by means of translation along a direction of movement substantially perpendicular to the direction of longitudinal extension of the earth moving machine 2.
  • Movement of the control console 14 may be enabled in any way, for example using selective lock/release means controlled by an activation key 18 mounted on the control console 14.
  • control console 14 can be moved between the operating position and the non-operating position using other methods, such as rotation (for example about an axis of rotation parallel with the axis of rotation of the seat 11 - as indicated below).
  • the seat 11 in many embodiments (such as backhoe loaders and other earth moving machines 2 with similar requirements), it can rotate relative to the chassis 3, between a first position in which it is facing a front part of the earth moving machine 2, and a second position in which it is facing a rear part of the earth moving machine 2 (in Figure 5 the seat is shown in an intermediate position during rotation).
  • control console 14 may be operatively associated with the seat 11 when the latter is located in the front position and/or when it is in the rear position.
  • control console 14 can also move between an operating configuration in which it is operatively associated with the seat 11 located in the first position (in this case positioned similarly to that shown in Figures 3 and 4), and a second operating configuration in which it is operatively associated with the seat 11 located in the second position (similarly to that shown in Figure 1).
  • the connecting portion 15 of the control console 14 is rotatably associated with the supporting element 10 below the seat 11, and can advantageously rotate about an axis of rotation parallel with the axis of rotation of the seat 11.
  • control console 14, as well as rotating can also move between the operating position and the non- operating position in both of the operating configurations.
  • the control console 14 when it is in the first operating configuration, can move between a first operating position and a first non-operating position (similarly to what is shown in Figures 3 and 4), and when it is in the second operating configuration, the control console 14 can also move between a second operating position and a second non-operating position (similarly to what is shown in Figures 1 and 2).
  • the working means 4 comprise at least a first and a second device associated respectively with a front portion and a rear portion of the earth moving machine 2. Consequently, the operating means 13 are operatively associated with both the first and the second device (consisting respectively of the loading shovel arm 7 and the articulated arm 7).
  • At least part of the operating means 13 mounted on the control console 14 can switch between a first operating condition in which they are operatively connected to the first device, and a second operating condition in which they are operatively connected to the second device.
  • switching is managed automatically based on the configuration of the control console 14 (first or second operating configuration).
  • this device is valid at least for one controller 21 (that illustrated in Figure 6) mounted on the control console 14, which based on the configuration of the control console 14 can switch between the first and the second operating condition.
  • the controller 21 is the only controller 21 of the control console 14 in the first operating condition.
  • control position 1 may comprise, instead of a single control console 14, two or more control consoles 14 each having a connecting portion 15 connected to the chassis 3 at least by a shock absorber 17 to damp, during use, the transmission of vibrations and shocks from the chassis 3 to the operating means 13 of the working means 4.
