Definitions

  • the present invention relates to "equipment for carrying out excavations such as trenches, pits, holes or the like, applicable to machines".
  • Document NL-A-6 403 391 presents equipment as indicated in point D, adapted on a tractor.
  • This equipment comprises a frame integral with the tractor, at the end of which projects a telescopic arm whose free end is provided with a working tool.
  • the sliding of the arm relative to the frame is carried out using a rack and pinion system which does not allow easy identification of the spacing of the tool relative to the axis of the frame.
  • the tool is fixed relative to the frame, and therefore relative to the tractor, so that, as previously explained, this equipment can only be used when the tractor is driven by a continuous translational movement and allows only the realization of a trench parallel to the axis of advance of the tractor and not of discontinuous excavations intended for reforestation.
  • the invention aims to remedy the drawbacks of known equipment and provides equipment designed to be adapted to machines that exist on the world market, such as crawler or wheeled excavators, tractors or excavators, crawlers or wheels. , etc ... whatever the brand, model or size of the machine.
  • This equipment comprises a frame capable of being mounted either on the front part or on the rear part of the machine and on the elements of which arms projecting in the form of telescopic slides protrude, being able to occupy stably different projection positions more or smaller and comprising at their free ends coupling means intended to receive working tools, so that the equipment makes it possible to carry out excavations such as trenches, pits or holes, etc. by being able to carry out one or two of these works in each machine parking situation.
  • the equipment is used with the machine stationary and the spacing distances between two rows of excavations and between excavations in the same row are specified.
  • the size and dimensions of the excavations are also specified, while the operator can selectively modify their lengths, widths and / or depths.
  • the tools are actuated using actuator elements coupled from a county to the coupling means and, on the other, to the frame and which can be constituted by cylinders, vases or cylinders, and which can be actuated using the hydraulic, pneumatic system, etc. which is provided with the machine on which the equipment object of the invention is mounted.
  • the arms and the frame have sets of corresponding orifices serving to fix the positions of the arms by means of bolts, so that the arms can carry out their telescopic movement relative to the frame either manually or automatically.
  • the frame is made symmetrically with respect to its median plane, so that the spacing is adjustable.
  • the coupling means used for mounting the working tools have complementary means constituted by a housing a configuration complementary to that of a tool head; the coupling is therefore established by simple embedding of the head in the housing, and a rigid connection is then established by means of screws, bolts or similar conventional elements.
  • This coupling system as will be seen in more detail throughout the digital memory, therefore allows simple and immediate mounting of the working instruments or tools, with appropriate safety solutions.
  • the object of the present invention is equipment adaptable to machines for making trenches, pits, holes or similar excavations; equipment which essentially consists of a frame (1); arms (2) having the form of telescopic slides and coupling means (3), provided for the corresponding working instruments or tools (4), which are set in motion by means of actuating elements (5).
  • the frame (1) is a hollow part which can be made of molten steel or else constructed of steel sheets assembled by welding or by any other similar embodiment, having a polygonal cross section, preferably square or rectangular, but without this being able to extend in a limiting sense.
  • the arms (2) can be produced in a form similar to the frame (1) and they have a configuration in cross section complementary to that of the frame (1); and so as to be able to describe a sliding movement inside this frame, like telescopic slides.
  • the arms (2) and the frame (1) have corresponding sets of orifices (6), so that by means of corresponding bolts (7) the arms (2) are fixed in the selected position, projecting more or less large, depending on the distance of spacing that it is desired to obtain between the working tools (4), to thus dig the holes or the specified excavation, with the spacing specified between these holes.
  • the insertion or extraction operation of the arms (2) relative to the frame (1) can be manual, as shown in the accompanying drawings, or it can be automatic, for example, performed using cylinders housed inside the frame (1), according to a conventional technical solution, similar to that used in the telescopic lifting arms or the elevation planes of mobile cranes and which will therefore not be described more fully detailed here.
  • the working tools (4) can be any tools chosen from among the tools existing on the market, provided that they are adapted to the coupling system of the coupling means (3) if this system has been specified.
  • the coupling means (3) offer the advantages of simple manufacture; the possibility of using any working tool (4) among those used in machines such as loaders, excavators, backhoes, etc. ; as well as great simplicity and rapidity of execution of assembly as well as disassembly of the tools (4).
  • a tool (4) is specially studied, since it has disintegrating teeth (10 ) assembled using metal blades (11), which act as a bucket bottom for extracting the hollow material.
  • the actuating elements (5) can be cylinders, vases, jacks or any other similar means, the actuation of which is carried out using the hydraulic, pneumatic system, etc. of the machine on which the proposed equipment is mounted.
  • the frame (1) For mounting the actuator elements (5), the frame (1) comprises plates produced with corresponding sets of orifices (12), in which the actuator elements (5) are fixed with bolts, according to a solution which makes it possible to rotate the latter as required and which makes it possible to arrange them selectively so as to form a more or less large projection.
  • FIG. 3 we can observe, by a view which represents half of the equipment, that this equipment has a symmetrical embodiment, how the actuation of the element (5) takes place with the movement of the tool (4) for digging an excavation or pit in the ground.
  • the frame (1) of the equipment may include complementary means allowing it to be mounted on the corresponding machine, or else to establish this assembly using bolts, conventional fastening elements, or even using of a permanent integral assembly, as is the case for that shown in FIG. 4, in which the frame (1) is fixed by welding to the chassis of the cutter or subsoiler (13) of a crawler tractor, as can be seen in detail in Figure 5.
  • the equipment can thus be mounted on practically any machine existing on the world market, for example loaders, agricultural or public works tractors, excavators, etc. and be arranged both on the front and on the rear of these machines.
  • FIG. 8 a possible practical alternative embodiment is shown which in no way alters the principle of the present invention.
  • the chassis (13) of the subsoiler or the cutter of a tractor is used as a frame (1) for the equipment and, at its ends, end pieces (15) are fitted which, in their attachment extension for the tool (4), different longitudinal dimensions, so as to allow different spacings between the working tools (4) to be obtained, depending on whether certain ends (15) or others are mounted.
  • FIG. 9 we observe, in a side view, the lifting arms (16) of the bucket of a shovel loader, so that, when the bucket has been removed, and using the fixing and rotation bolts of this bucket, it can be coupled to the frame (1) of the proposed equipment.
  • an excavating machine is represented diagrammatically, indicating how the frame (1) of the equipment can be mounted on the end of the basic boom (17) or on the end of the boom (18), or on that of the pendulum (19), replacing the bucket (20).
  • An advantage brought by the incorporation of this equipment in this type of machine consists in that one can carry out the work on a radius of action of 360 ° and, while the machine is immobilized, all this by simply acting on the machine turret rotation controls.
  • the operator places the arms (2) at the desired spacing, manually or automatically, and immobilizes them in this position.
  • the operator raises all the equipment, by actuating the controls of the subsoiler of the towing machine, and places the latter on the upper part of the slope, and with the direction of travel directed towards the bottom.
  • the machine remaining immobilized, it executes the first two holes, by lowering the equipment using the controls of the subsoiler, until penetrating part of the tip of the teeth of the working tools (4) and by actuating then the cylinders (5) to put them to the desired length, and, for this, he can actuate the two cylinders (5) simultaneously or one after the other, as desired.
  • Figures 11 and 12 show a possible non-limiting example of practical embodiment of the coupling means (3), with a safety device.
  • the entry of the head (9) of the working tool (4) into the housing (8) of the coupling means (3) is fixed using a bolt (23) which penetrates in a groove (24) of the head (9).
  • the bolt (23) is pushed by a spring (22), the tension of which is adjusted using a screw (21).
  • the bolt (23) escapes from the groove (24) thereby allowing the head (9) of the tool and, consequently, this tool, to escape from the coupling (3).
