Definitions

  • 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 and such as described in WO-95/26445 .
  • 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.
  • 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.
  • 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.
  • WO9526445 discloses a multifunction auxiliary tool comprised of a levelling blade with vibrating shoes for making road embankments and providing other types of fine grading.
  • the tool is designed to be combined with various units such as adjustable flaps, mechanical bucket, hydraulic bucket and fine grading means, for transporting, levelling, mixing and compacting with the vibrating shoe. Compression means are used to apply pressure on the materials levelled by the blade.
  • the object of the present invention is defined in claims 1 to 14 and comprises an implement of a caterpillar track machine for spreading gravels or aggregates comprising:
  • 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.
  • 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.
  • 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.
  • 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.
  • the implement 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.
