Definitions

  • the invention relates to a firewood circular saw with a protective housing for the saw blade.
  • the saw blade associated, mounted on the frame protective housing is integrally formed. Accordingly, the working gap is determined in size. Logs or trunk sections whose diameters are larger than the clear opening of the working slit can not be sawn off. As a rule, however, firewood is not sorted by diameter, so that logs or rollers with a comparatively large diameter can be contained in a batch. These have to be split into shorter pieces before subdivision. The known arrangements therefore prove to be not user friendly enough.
  • the upper part of the protective housing is widely spaced from the lower part. Between the upper part and the lower part in the known arrangement another, closed at the rear middle part be provided. Whether in this case the upper part relative to the central part or the middle part relative to the lower part are pivotable, is from the EP 0071902 A2 not visible.
  • the provided in the known arrangement middle part leads to increased effort, and to a high lability and thus risk of vibration.
  • firewood circular saws usually only perform a comparatively rough cut, which leads to the excitation of vibrations. From the cited document, there is no upper stop for limiting the pivoting movement. The absence of an upper stop can cause damage and accidents.
  • the upper part of the protective housing is mounted concentrically to the saw shaft and so far pivoted that the working gap completely disappears. It is therefore necessary to push up the upper not only when sawing from a comparatively large diameter having firewood but even with comparatively thin woods. This is awkward and promotes the risk of accidents.
  • An upper, the pivotal movement limiting stop is not provided.
  • FIGS. 1 and 2 illustrated constructed according to the WippsägenBF firewood circular saw contains a mobile machine frame 1, which is expediently constructed in the manner of a truncated pyramid.
  • a shaft 2 is mounted, which cooperates on the one hand with a drive motor, not shown, and on the other hand carries a machine frame on one side flanking saw blade 3.
  • a receiving channel for sawing material having feed member is provided at the front of the machine frame 1, a relative to the stationary blade 3 movable.
  • This is formed in the example shown as an axis parallel to the saw blade axis pivotable rocker 4, which has a receiving channel 5 for the pole containing, in cross-section v-shaped receiving piece 6.
  • the saw blade 3 is associated with a mounted on the adjacent side edge of the machine frame 1 protective housing. This consists of a lower portion of the saw blade 3 receiving lower part 7 and a cross-over this, an upper portion of the saw blade 3 associated Upper part 8.
  • the upper edge of the lower part 7 is rising from front to rear.
  • the lower edge of the upper part 8 is sloping from front to back.
  • a working gap 9 opening towards the advancing member is limited.
  • the clear input width of the working gap 9 limits the permissible thickness of the workable shegeguts.
  • the upper part 8 is about an axis 10 parallel to the saw blade axis of a lower, the FIG. 1 underlying stop position in an upper, the FIG. 2 underlying stop position can be pivoted upwards.
  • the upward pivoting movement is expediently counter to the force of a restoring device, which automatically returns the upper part 8 to the lower stop position.
  • woods with normal diameter of in FIG. 1 be cut at 11a indicated kind.
  • firewood batches can also be wood with a much larger diameter in FIG. 1 included in 11 b indicated type. If such woods come, the clear input width of the working gap 9 is increased by corresponding pivoting of the upper part 8, such as FIG. 2 clearly shows.
  • Such woods will, as FIG. 2 shows further, in the first cut to slightly more cut over the middle and must be rotated for another separation cut by about 180 °.
  • the pivot axis 10 of the upper part 8 is located in the rear, that is in the area of the protective housing remote from the entrance of the working gap 9.
  • the lateral guide plates 12 are provided. These are expediently formed as flat sheets, which bear against the opposite inner sides of the lower part 7 forming box and are connected to the box side walls. The rear edge of said tabs may rest against the rear wall of the box.
  • the upper part 8 is expediently designed as a downwardly open, in cross-section U-shaped box, in which the guide plates 12 engage. These lie on the box inside, so that there is a reliable, lateral guidance.
  • FIG. 4 For storage of the pivotable upper part 8 is a lateral guide tabs 12 bridging, in FIG. 4 indicated bolt 10 a is provided, which projects beyond the lateral guide plates 12 with its ends and in associated, in FIG. 4 Above visible holes 10b of the upper part 8 forming box engages. At least one, preferably both of the guide plates 12 carrying the bolts 10a are as shown FIG. 4 below further shows, provided with a bolt axis to the axis and thus to the pivot axis of the upper part 8 concentric arcuate slot 13.
  • the upper part 8 contains the curved slot 13 of a guide plate 12 in the example shown, the aligned arcuate slots 13 of both guide plates 12 associated, laterally projecting, in FIG. 4 above indicated pins 14, which engage in the respectively adjacent curved slot 13.
  • the upper part 8 may be provided with a side projecting pin bridging its lateral walls.
  • Each of the engaging in an arcuate slot 13 pin 14 acts as a stop member, which starts to limit the pivot angle of the upper part 8 at the ends of the associated arcuate slot 13. In the lower position, the stops are at the lower end, in the upper position at the upper end of the associated curved slot 13.
  • spring 15 is provided for forming the above-mentioned restoring means.
  • This is formed in the example shown as a tension spring, the upper end of the upper part 8 and the lower end of the lower part 7 attack.
  • the upper end of the spring 15 may suitably engage the abovementioned pin 14a provided for forming the pins 14.
  • the lower end of the spring 15 can engage a pin 16 bridging the guide tabs 12 or side walls of the lower part 7.
  • the restoring device can also be formed by a spring arrangement containing a plurality of springs. The use of other types of springs, such as a bow spring, etc. would be conceivable.
  • the bearing remote end of the upper part 8 is useful as formed with the lower edge of the upper part 8 an obtuse angle forming run-on slope 17.
  • Thicker blanks of in FIG. 1 at 11 b indicated type run as out FIG. 1 can be seen on the run-on slope 17, whereby the upper part 8 is raised.
  • the adjoining the run-on slope 17 lower edge 18 of the upper part 8 is formed concave with respect to the axis of the saw blade 3. This facilitates the sliding of the upper part 8 on a piece of wood which presses it upwards, as seen in FIG FIG. 2 is clearly recognizable.
  • the recording channel 5 containing, in cross-section v-shaped receiving piece 6 is provided with a saw blade 3 associated slot into which the saw blade 3 can dive to make a cut.
  • the saw blade 3 is also protected in the region of the working gap 9 in such a way that no engagement is possible from the side.
  • the receiving piece 6 flanking with the aforementioned slot, best of FIG. 1 recognizable Abdeckschilden 19 provided which engage in the lower part 7 and upper part 8 forming, each U-shaped box.
  • the cover plates 19 are provided with recesses associated with the shaft 2 or the saw blade attachment. These would be in the FIG. 1 underlying, submerged position allow lateral access to the saw blade 3.
  • the receiving piece 6 is provided with with respect to said recesses laterally offset covers 20 which flank the lower part 7 laterally in the lowest engagement position, as seen from FIG. 2 evident.
  • the lower part 7 is provided in the region of the rear lower corner with an ejection opening 21 provided here in the lower region of the narrow rear wall, via which the airflow generated by the saw blade 3 can emerge and sawdust can be ejected.
  • the outlet opening 21 may open into the environment or into an associated disposal facility.
  • the ejection opening 21 is associated with a fixed to the lower part 7 connector 22 having a connection piece 23 for connecting a suction hose or a like a filter basket or the like. Trapped container. Of course, it would also be conceivable to connect such a collecting container directly to the lower part 7.
