Definitions

  • the invention relates to an attachment for attachment to the boom or frame of hydraulic excavators, backhoe loaders, front loaders and similar devices, in which rotatably mounted in a frame and driven by an eydraulic motor, there is a drive shaft to which tools for cutting or milling can be attached wherein the attachment can be supported on the road surface or the like by a support and depth adjustment device for the tool.
  • attachments can be varied, since various tools can be attached to the shaft, such as a milling drum for road milling, a joint milling disc for joint cutting or a trench milling machine for trench milling.
  • a support and depth adjustment device is necessary or advantageous. All road milling machines and joint cutters, whether self-propelled or as attachments, are equipped with support and depth adjustment devices. In most cases, these devices are designed so that a roller that runs on the road surface is connected to the frame of the device via an adjustable spindle and, at the same time, the milling drum is firmly attached to this frame. By adjusting the spindle, the frame with the milling drum is raised or lowered. When lowering, the roller mills the surface of the road.
  • this support and depth adjustment device achieves the following: firstly, the milling depth is determined by the position of the spindle, secondly, the machine supports the device, thirdly, the roller on the road prevents the milling drum, e.g. by vibrations can penetrate deeper than was set, fourthly, the greatest possible weight is shifted onto the milling drum, which leads to the greatest possible transmission of the available power. If the speed was too high, the milling drum and thus the roller would be raised. The fact that the roll is in contact also indicates that the correct milling depth is being maintained. Fifth, this construction of the support and depth adjustment device prevents vibrations caused by the milling drum from being transmitted to the device.
  • the support and depth adjustment devices listed above cannot be used for attachments that have to be moved with the boom. This is because the boom movement constantly changes the angular position of the milling device attached to the boom and the support roller connected to it. This changes the fixed height ratio between the frame, support roller and milling drum or milling disk.
  • the driver has to adjust the angular position of the frame during the continuous boom adjustment caused by the advancement of the milling device Constantly change the actuation of the valve lever for the bucket cylinder so that the desired depth is maintained.
  • joint cutters with thrust washers can only be used in warm seasons when the asphalt is warm and soft. In the cold season, the asphalt is too hard to be pressed in with thrust washers, unless very heavy carriers are used.
  • Another limitation of the thrust washers is that they can practically only be used to a depth of about 8-10 cm. Greater depths can only be reached with very heavy carrier equipment. Joint milling discs can be used all year round, even at greater depths. They can also be used to work much faster.
  • the invention has for its object to develop a support and depth adjustment device that automatically maintains the set depth when the boom of an excavator or similar device is guided from the nearest machine point to the outermost range or vice versa and road milling or joint cutting work is carried out.
  • rollers of the support and depth adjustment device are constantly pressed onto the road surface and thus the milling drum or milling disk can be pressed into the road surface at the desired depth, while the boom extends from the outermost range to machine next point is moved.
  • a shaft (11) runs in a frame (1), driven by the hydraulic motor (4) via the transmission (3).
  • Either a joint milling disc (8) or a milling drum (7) can be attached to the flanges on the flanges.
  • the support and depth adjustment device for the milling drum and the milling disk is suspended so that the drive wheels swing freely, so that their support wheels can be pressed onto the road surface in any position of the boom.
  • the support and depth adjustment device consists of the rockers (5) and the support rollers (6) attached to the lower end as well as an adjusting spindle (10) with which the milling or cutting depth is set.
  • a mounting plate (9) is attached to the upper part of the frame and is connected to the boom of the excavator or backhoe loader or front loader by two bolts.
  • the hydraulic motor is driven by the hydraulic system of the excavator, backhoe loader or front loader.
