Definitions

  • the present invention relates to a self-loading vehicle with loading arm.
  • Powered mechanical vehicles used to transport various materials in construction sites, are usually loaded manually or with the help of a second powered vehicle (almost always an excavator or a front loader).
  • a second powered vehicle almost always an excavator or a front loader.
  • auxiliary equipment such as buckets and loading arms, with one degree of freedom with respect to a dump body (or flatbed) used to collect the material.
  • Mini-carriers in which the loading means are fastened directly to the dump body have the advantage of automatically solving the problem of the mechanical interference between the bucket and the dump body when loading.
  • the stress transmission system causes wear in the pins and results in backlash which can jeopardise the correct operation of the machine, greatly shortening its useful working life.
  • the structure of the vehicle forces the operator to stay in the erect position when the vehicle moves, as otherwise he would not be able to see the area where the tool is working.
  • Mini-carriers whose loading arms are fastened to the lower chassis have better structural strength than the others and can employ lighter dump bodies, which may be obtained by pressing.
  • these mini-carriers have been provided with a rather complex and cumbersome hydraulic device which regulates the motion of both dump body and tool.
  • the purpose of the present invention therefore is to eliminate the drawbacks just mentioned.
  • the invention as it is characterised by the claims, solves the problem of providing the tool in use with one degree of freedom with respect to the arm which supports it.
  • One of the advantages obtained through the present invention essentially consists of the fact that the potential of these powered vehicles is greatly enhanced, so they are much better suited to be combined to several tools with no need for laborious fitting operations.
  • an important advantage stems from the fact that the latter may be used with several other functions as well: for instance, as an excavator, to fill trenches or, by reducing bumps, to ease travel over uneven or stepped terrains.
  • the invention allows to maintain a good view of the area where the tool is working even when the operator sits in the driver seat.
  • the present invention relates to a self-loading vehicle with loading arm, of the type comprising a lower chassis (4), a body (7) for the collection of materials and at least one arm (3) for supporting a tool (2).
  • the invention provides for the presence of a connecting mechanism (1) interposed between the arms (3) and the tool (2), able to give the latter the ability to rotate with respect to the arms (3).
  • this mechanism (1) comprises a pair of extendible cylinders (5), hinged at their ends to the arms (3) and to the tool (2), and a pair of hinges (9) also constraining the arms (3) and the tool (2), so that the latter can assume an arbitrary inclination with respect to the arms (3).
  • such device (6) comprises a plate (12) which can be securely made fast to the connection mechanism (1) and fitted with means (13) for coupling it to a tool (2).
  • These coupling means (13) in turn comprise a cross bar (14), able to intercept at least a pair of corresponding hooks (15) of the tool (2), and a latch (16), able to secure a slot (17) of the tool (2), protruding from its rear surface.
  • the cross bar (14) is inserted under the hooks (15) and then raised and possibly rotated to let the latch (16) interfere with the slot (17).
  • the latch (16) can be shut manually as well as with a remote control (18), so the operator can control it with the vehicle (20) in motion and remaining in the driver seat.
  • the embodiment depicted in Figure 2 shows a pair of wheels (10) fitted to the tool (2) in correspondence with the mechanism (1) providing connection to the arm (3): it is particularly advantageous in the case of moderate differences in level, since it allows to keep the tool (2) operating even in the course of moves. As is shown, by virtue of the degree of freedom provided the tool (2), it is possible to let the wheels (10) come in contact with the ground rotating the tool (2) itself counter-clockwise and lowering the arm (3). In case of greater differences in level, it is instead advantageous to adopt the solution shown in Figure 3, in which the same pair of wheels, or possibly a second one, is fitted to the tool (2) in correspondence with its front end, to obtain a support extension for the machine of the maximum possible length.
  • the swinging door (8) hinged at the front end of the dump body (7) and kept in the vertical position, during transport, by two hooks (19) which open automatically when the dump body (7) is lifted, allowing the material contained inside it to be off-loaded.
  • the upper edge of the swinging door (8) is lower than the edge of the dump body (7), so that its reduced size can provide the operator with a better visibility.
  • the swinging door (8) comprises an upper part (8a) made up of a grid, particularly useful in case of transport over very steep terrain, as it allows for a better containment of the transported material without jeopardising the operator ability to see the tool (2).
  • Additional uses to which the invention associated to a bucket can be advantageously applied can pertain to the excavation and filling of trenches and handling accumulations of material.
  • Other tools which can easily be associated to it are the hydraulic hammer, whose tip can be oriented arbitrarily, a catenary trench digger, usable with reverse movements and optimising the angle of the equipment with respect to the terrain, snow blowers and snow ploughs.
