Definitions

  • the present invention relates to "equipment for making trenches, pits, holes or the like, applicable to machines".
  • an equipment designed to be adapted to the machines which exist on the world market, such as wheeled excavators with tracks or wheels, tractors or excavators, tracked or wheeled, etc., whatever the make, model or size of the machine, so that the equipment can be mounted either on the front or on the rear of the machine , and that it makes it possible to execute the opening of trenches, pits or holes, etc., by being able to execute one or two of these works in each parking situation of the machine; with the machine stationary and with the spacing distances specified in each case, as well as with the size and dimensions specified, at the same time that the operator can selectively modify the lengths, widths and / or depths.
  • the equipment object of the present invention consists essentially of a chassis or frame of large width, intended to establish through it the coupling between the equipment and the machine on which it is to be mounted.
  • Each of these arms has at its free end a particular coupling system for the various instruments or working tools.
  • This coupling system allows simple and immediate mounting of the working instruments or tools, with appropriate safety solutions.
  • means for actuating said tools are arranged, which can be constituted by cylinders, vases or jacks, 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 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 made 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, protruding 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 suitable for 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 the extraction of 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 observe, by a view which represents half of the equipment, that this equipment has a symmetrical embodiment, how the actuation of the element (5) is effected 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 making it possible to mount it on the corresponding machine, or else to establish this assembly using bolts, conventional fasteners, or even using of a permanent integral assembly, as is the case for what is 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 all the machines existing on the world market, for example loader shovels, 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 of 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 thus obtain different spacings between the working tools (4), depending on whether certain tips (15) or others are mounted.
  • FIG. 9 we observe, in a side view, the lifting arms (16) of the bucket of a loader shovel, so that, when the bucket has been removed, and using the fixing and rotation bolts of this bucket, we can couple 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).
  • Figures 13 and 14 show the same solution as in Figures 11 and 12, but replacing the spring (22) with a block of synthetic material (25), such as rubber; on the contrary, in Figures 15 and 16, the adjusting screw (21) has been replaced by an articulated lever (26), which can be fixed in different positions, using the corresponding pin and the assembly d orifices (27) thereby establishing different degrees of compression of the spring (22).
