Definitions

  • This device which was also invented by the applicant of this invention, is very effective for digging trenches of less width, such as are necessary for cables and water pipes, and for mounting on medium-sized excavators and backhoe loaders, but when the trenches become wider and larger Excavators must be used, so it is necessary that the holder for the two milling drums is stronger in the middle. This results in a larger width of the holder. This requires a smaller angle of the milling drums to each other in order to obtain the price cut in the middle between the two pres rollers. This smaller angle means larger distances between the front outer edge of the roller and the rear outer edge of the roller. These eventually become so large that they can no longer be bridged by chisels protruding from the side.
  • the object underlying the invention is to avoid the disadvantages described here. That on the one hand also to enable trench excavation work in soft rock if larger trench widths are available and when larger excavators with higher performance are used and on the other hand to develop a device for excavating narrower trenches that can be manufactured inexpensively and offered at low cost.
  • a device which consists of a combination of a pre-device and a container, the pre-device and the container being designed in relation to one another in such a way that the material loosened by the pre-device is conveyed into the container by it that at the edge or the edges of the milling tool, for example the milling drum of the pres device is attached to the holder or to the holders towards chisels or chisel holders which can be folded towards the holder. Further developments of the device according to the invention can be found in claims 2 to 12.
  • the device according to the invention can now be used here much more cost-effectively and in an environmentally friendly manner.
  • the device according to the invention can be manufactured much more cheaply and more cheaply than is possible with a device to be manufactured as described in the published patent application DE 3603675 A1.
  • the reason for this is that one holder can be attached to each side of the spoon in such a way that they extend forward over the length of the spoon. This makes it possible for the roller itself to have enough space for installing a hydraulic motor. For this reason, the high costs for the bevel gear drive, as is required in the construction according to DE 3603675 A1, for the production of a rock-cutting bucket for narrow digging widths are eliminated.
  • the holder of the milling drum by two laterally attached holders is possible in that the two lateral holders are cut free on the two outer edges of the milling drum with the aid of the folding chisel.
  • FIG. 1 shows a top view of the milling spoon with the milling device and the folding chisel holders Fig. 2 Side view of the milling bucket with the milling device with folding chisel holder Fig. 3 folding chisel holder with round shank chisel in a vertical position at the edge of the milling drum Fig. 4 folding chisel holder with round shank chisel in the folded position.
  • the milled material receptacle in the form of a deep-sea ice (1) is attached to the rear and the milling device consisting of holders (2), milling drum (3) with hydraulic motor (13) at the front, the chisel holders (6) fixed on the milling drum (6) with picks (11) and the hinged chisel holders (4 and 5) with picks (11).
  • the holder (2) is the surface of the guide plate (7), which is slanted towards the rear in the direction of the milling cutter's chisel, through which the Ruöichaft chisel and chisel holder are returned to the vertical position (5), after having previously been pressed by Milling were brought into the inclined position (4).
  • This process of folding back can take place instead of using the guide plate or additionally using a spring (12).
  • the connection between the chisel holder and the milling drum is made by a pin-socket connection (14). Folding the chisel holder is limited on both sides by an attachment point (15 and 16).
  • the milling spoon is supported by the support roller (17) and the pre-depth is regulated.
  • the milling device is covered by the movable flap (18).
