Definitions

  • the invention relates to a bottom blade as defined in the preamble of claim 1.
  • Bottom blades are used in working vehicles, such as trucks and tractors, in road maintenance to shape and/or work on the masses.
  • the bottom blade is provided under the frame of a vehicle between the axles.
  • the bottom blade may be used both in summer and winter. In winter, plowing the snow, grading thick ice and removing the slush may be performed by a bottom blade simultaneously with the other road maintenance tasks. In summer, working on gravel roads, moving and grading of gravel and other masses can be performed efficiently with a bottom blade.
  • a bottom blade of a truck comprising a main blade provided with a first cutting edge in the lower part thereof to be contacted with the underlying ground.
  • a slide frame has been directed to move in the direction of the main blade in the guidance of slide guides.
  • An extension blade has been connected to the slide frame to move relative to the main blade between a first position and a second position. In the first position, the extension blade is protruded to a distance outside the end of the main blade. In the second position, it is retracted to a position where the extension blade and the main blade are disposed one upon the other.
  • the extension blade is provided with a second cutting edge in the lower part thereof to be contacted with the underlying ground.
  • An extending/shortening type power means such as a hydraulic cylinder, has been arranged to act between the slide frame and the main blade to move the extension blade between the first position and the second position.
  • a problem with the known bottom blades provided with an extension blade is that when the extension blade is protruded, it is disposed on the front or back side of the main blade during use, depending on which side of the main blade it has been provided on. In this case, the cutting edges of the main and the extension blade are not aligned with to each other. This causes discontinuity in the work result, so that at the extension blade the working depth is different, for example deeper or lower, than at the main blade. In addition, the difference in the working depths varies according to the angle in which the main blade is tilted relative to the underlying ground.
  • the objective of the invention is to eliminate the drawbacks referred to above.
  • the objective of the invention is to disclose a bottom blade in which the cutting of the extension blade is always aligned with the cutting edge of the main blade on the same cutting level during use, irrespective of the current angle relative to the underlying ground set for the main blade.
  • the bottom blade according to the invention is characterized by what has been presented in claim 1.
  • the extension blade is jointed by a joint to the slide frame to turn about a pivoting axis parallel to the main blade so that in the first position of the extension blade when the main blade is pressed against the underlying ground the extension blade turns relative to the main blade to a turned position in which the second cutting edge is aligned with the first cutting edge.
  • the advantage of the invention is that the second cutting edge of the extension blade always works in alignment with the first cutting edge of the main blade on the same cutting level, irrespective of the current angle set for the main blade relative to the underlay so that the extension blade and the main blade always provide the same cutting depth.
  • the extension blade is on the front side of the main blade and the slide frame is on the back side of the main blade.
  • a stop is mounted to the main blade and fitted to stop the turning of the extension blade in the position where the first cutting edge and the second cutting edge are aligned with each other.
  • the joint is above the main blade and on the back side thereof.
  • Fig. 1 is a view of the left side end of a bottom blade mountable under a working vehicle, such as a truck or a tractor.
  • Fig. 2 to 4 illustrate the bringing of an extension blade 5 of the bottom blade into a service position.
  • the bottom blade comprises a main blade 1.
  • the lower part of the main blade 1 is provided with a first cutting edge 2 to be contacted with the underlying ground.
  • slide guides 3 are arranged on the back side of the main blade 1 to guide a slide frame 4 to move in the direction of the main blade 1.
  • a hydraulic cylinder 7 is connected at one end to the main blade and at the other end to the slide frame 4 to move an extension blade 5 between a first position I and a second position II.
  • the extension blade 5 has been connected to the slide frame 4 to move relative to the main blade 1 between the first position I and the second position II.
  • the extension blade 5 In the second position II presented in Fig. 1 and 2 the extension blade 5 is retracted to a position where the extension blade 5 and the main blade 1 are disposed substantially one upon the other so that the extension blade 5 is on the front side of the main blade 1.
  • the lower part of the extension blade 5 is provided with a second cutting edge 6 to be contacted with the underlying ground.
  • the figures show that the first cutting edge 2 and the second cutting edge 6 are so-called stud blades, but it is apparent that any cutting edge suitable for the current task, such as a flat blade, perforated blade, serrated blade, is applicable.
  • the extension blade 5 has been jointed to the slide frame 4 with a joint 7 to turn about a pivoting axis X in the direction of the main blade 1.
  • the joint 7 is positioned above the main blade 1 on the back side thereof.
  • the joint 7 is formed by a shaft mounted to the extension blade 5 and a bushing mounted to the slide frame 4, the shaft being fitted with a bearing to rotate inside the bushing.
  • a stop 8 mounted to the back side of the main blade 1 is a stop 8 formed by two flanges welded to the main blade.
  • the stop 8 stops the turning of the extension blade 5 so as to not turn further than the position A where the first cutting edge 2 and the second cutting edge 6 are aligned with each other as presented in Fig. 6 .
  • Fig. 7 shows that when contacted with the underlay, the bottom blade can be turned to different angular positions, and the first cutting edge 2 and the second cutting edge 6 are always aligned with each other so as to have a smooth performance.
