Definitions

  • the present invention relates to a multipurpose machine of a new type, intended to be used in particular for public works in the building industry, or on handling or earthworks.
  • a known type of device is the adjustable backhoe. It includes a frame movable on wheels, and carrying a vertical pivot, around which can rotate a cabin which overcomes the assembly, this control cabin also carrying the base of an articulated arm, the free end of which is ends with an excavator bucket.
  • the revolving floor of the pivoting cabin notably includes a hydraulic unit actuated by a heat engine, as well as a control station from which the operator, seated in the cabin, can control, on the one hand, the jacks actuating the articulated arm and the excavator bucket, on the other hand, the rotation of the cabin.
  • This known type of device is used as a backhoe, as an excavator, or to dig trenches of varying lengths.
  • a loader Another machine of a different type is known as a loader. Its chassis, also mobile on wheels, carries the basic articulation of a lifting arm, the free end of which is fitted with a loader bucket.
  • the chassis is surmounted by a cabin where the operator, from his control station, can control the movements of the machine, in particular by means of hydraulic jacks actuating the arm and the bucket.
  • Vehicles of this type are used to take a load from the ground, and raise it a few meters before depositing it, or vice versa.
  • Excavators and loaders of the type just described constitute separate devices, so that a user whose site corresponds to both shoveling operations and loading operations must obtain two expensive devices separately. This results in a considerable financial constraint, so that, on many sites, contractors having only one machine, are brought to make it work in bad conditions, during operations for which it was not planned. .
  • the object of the present invention is to avoid these drawbacks, by making a single, but versatile machine, well suited for multiple uses on a site.
  • the lifting lifting arm is telescopic, formed of two elements sliding one inside the other, and actuated by a telescoping jack.
  • the heat engine and the hydraulic unit are placed on the rotating floor of the cabin, while a hydraulic seal rotating with more than ten passages tightly connects the fixed part of the hydraulic circuit carried by the chassis, and the mobile part of the hydraulic chassis carried by the pivoting cabin, and by the shoveling arm.
  • the part of the hydraulic circuit carried by the chassis also actuates, on the one hand, the lifting stabilizer jacks on the ground, on the other hand, the hydraulic motors incorporated in the wheels of the machine , whose transmission is hydrostatic.
  • the machine illustrated in the drawings comprises a chassis 1, carried by wheels 2.
  • the chassis 1 is equipped with an orientation crown 3, which is surmounted by a cabin 4, so that the latter can rotate 360 °, around the geometric pivot axis 5, defined by the cabin 4.
  • a control station defined by a seat 6, and a cockpit 7. Furthermore, the floor of the cabin 4 is integral with a hydraulic unit 8, comprising in particular an oil reservoir not shown, a heat engine 9, and two hydraulic pumps 10 and 11.
  • the floor of the cabin 4 is also integral with a base 12, on which the foot 13 of a shoveling arm is articulated, the head 14 of which carries, at its end, an excavator fodet 15.
  • the various movements of the articulated assembly 13, 14, 15 are controlled by hydraulic cylinders such as 16, 17, 18.
  • the telescoping of the arm 20, 21 is controlled by an internal hydraulic cylinder 35 Furthermore, the tilting movements of the tool holder 22 relative to the arm head 21 are controlled by a hydraulic cylinder 26.
  • chassis 1 comprises two stabilizers 27, of known type, the lifting of which is also controlled by jacks not shown.
  • the rotary joint 36 most often includes a number of passages greater than ten, for example fifteen passages.
  • the lifting arm 20 is not telescopic, but it can be raised up to an angle 43, the maximum value of which is of the order of 60 °.
  • the lifting tool which can be a loader bucket 23 or a handling fork 42, can be raised above the ground, to a height 44 at least equal to 2.80 meters.
  • the aforementioned lifting angle 43 leads to lifting the tool 23 or 42 above the ground, up to a height 45, for example of the order of 4.10 meters.
  • the apparatus according to the invention can be used in the manner of a forklift, which was not the case with any of the previously known machines comprising a simple pusher shield always working at a level close to the ground.
