Description

    Object of the Invention
  • As established by the title, the object of the present invention is an implement of a caterpillar track machine for spreading gravels or aggregates, an implement being understood as an additional tool which allows spreading stones, gravels, aggregates, ballasts or any other spreadable material when assembled on a caterpillar track-type machine such as backhoes.
  • The present invention is characterized by the special constructive features of the implement which, on one hand, allow easy assembly and disassembly on/from a caterpillar track-type machine; it has certain measurements allowing transport in a conventional trailer or truck, in addition to enabling the unloading and subsequent assembly thereof by means of the backhoe machine to which it is attached and with which it works.
  • In addition to said operative advantages, a more than significant increase in the performance and speed of spreading gravels, aggregates and the like is obtained.
  • Therefore, the present invention is comprised within the field of machines for spreading gravels or aggregates or the like, as well as within the scope of implements for attachments that can be assembled in excavator machines.
    • Background of the Invention
  • The aggregate and fine gravel spreading machine described in the utility model with application number ES9200018U and published as ES 1019816U is known in the state of the art.
  • Said utility model discloses an improved aggregate and fine gravel spreading machine of the types intended for being used, by means of the appropriate towing thereof, to distribute the aggregates and fine gravels by means of the towing thereof by a conventional vehicle, having skid wheels, characterized in that it is provided with a hydraulic motor (1), a drive cylinder (2) for driving the belt, a support bearing (3) for the drive cylinder, an idler cylinder (4) for the belt, and a conveyor belt band (5). Furthermore, it has a container (14) for storing the aggregate which has a product outlet (15), having a towing hitch (16).
  • The operation and performance of said machine is limited due to the fact that it is designed for spreading fine gravels and the like from a container assembled on the machine itself. This is because the container for the fine gravel has a limited volume, in addition to entailing an additional load for transport.
  • Now, what is sought is to enable spreading gravels or aggregates previously arranged on the ground in a uniform, quick and height adjustable manner, with high performance and great capacity for handling large volumes of material to be spread, developing for these purposes a machine such as that described below and the essential features of which are included in claim 1.
    • Description of the Invention
  • The object of the present invention is an implement of a caterpillar track machine for spreading gravels or aggregates comprising:
    • Two laterally arranged caterpillar tracks having in their inner face protection and support means for
    • An upper structure which provides support to
    • An arrowhead-shaped spreader structure arranged in the lower portion with respect to the upper structure
    • Attachment means for attaching both the upper structure and the spreader structure with the machine on which the implement is to be assembled.
    • Adjustment means for adjusting the relative height of the spreader structure with respect to the upper structure, and therefore the level or height at which the material to be spread is to be left.
    • Hydraulic actuating means.
  • The attachment of the spreader structure with the upper structure is height adjustable by means of several height adjustable attachment points, being able to have one front attachment point, another rear attachment point, and one or several intermediate attachment points.
  • Additionally, and in order to reinforce the structural stability of the assembly, the upper structure is attached by means of beams or bars extending from the upper structure to the backhoe machine. The spreader structure also has several bars attached in an articulated manner between said structure and the backhoe machine.
  • The attachment bars between the different structures, the upper structure, the spreader structure, and between the preceding structures and the backhoe machine are articulated attachments allowing a certain play and clearance, preventing a stiff structure or frame which may be subjected to forces and torques that could break the structure.
  • Additionally and complementarily, the implement can have counterweights arranged on a portion of the structure. Said counterweights aim to prevent the implement from being lifted up in response to the thrust force of the backhoe and the resistance of the gravel to be spread.
  • In a possible embodiment, the counterweights are arranged on the side caterpillar tracks of the implement, on a structure fixed to the inner structure of the caterpillar tracks. The counterweights comprise a bin open at the top that can be filled with the actual stones or ballasts to be spread.
  • In addition to easy transport, the implement can be assembled and disassembled as a result of its structural features. The measurements thereof allow transport in a conventional trailer or truck and both unloading and assembly are performed by means of the backhoe to which it is attached and with which it works.
  • In practice, first the backhoe arrives at the work site, if it is not already there, and the implements are unloaded and assembled with said backhoe.
  • The working speed is 3 or 4 times greater than the means used today, which greatly increases the performance.
  • It allows adjusting the height of the gravel layer with greater ease and precision. Furthermore, the quality of the finishing is exceptional. Complete uniformity in the gravel layer is achieved.
