The specific embodiment
Be used for the round log bark or prepare round log, so as to carry out separately bark-especially for the round log of difficult bark-equipment be shown among Fig. 1 as the perspective view of signal.Equipment is with shown in the side of discharge end.Fig. 2 illustrates the side view of equipment, and wherein, the direction of feed of round log marks with arrow A.Fig. 3 further shows the cutaway view along the III-III line of Fig. 2.
Equipment comprises a cylinder 3 around its central axis 2 rotations, and pending round log is admitted to by the space that the cylinder-shaped inner sleeve 4 by this cylinder limits, and thus, round log is dawdled and impacted, to handle bark.Cylinder 3 is supported in the position of an inclination by this way, so that central axis 2 is with respect to horizontal plane α in an acute angle.The size of angle [alpha] is in 2 °-12 ° scope.Value commonly used is about 5 °.
In the example shown in the figure, cylinder 3 is supported on the wheel 12 from the outside, and is provided with common device with reference number 13 representatives, to be used for swing roller 3.
For the sake of clarity, round log 1 is fed to the conveyer in the cylinder 3 and will further be delivered to from the round log 1 that the discharge end of cylinder 3 is discharged below the processing stage conveyer, all from figure, omit.
In example shown in Figure 1, on the surface of the inner sleeve 4 of cylinder 3, arrange one or most preferably be several carinate projections 8, these projections are twined by the mode of helix with respect to the central axis of cylinder.Be arranged in the example of rotation in the direction of arrow B at the cylinder shown in the accompanying drawing 13, ridge projections 8 forms the winding of dextrorotation.In the case, rotatablely moving in power that acts on the round log 1 that leans against on the projection 8 of discharge end generation of cylinder 3 of cylinder 3 that is to say that generation one is along the power of the direction of arrow A shown in Figure 2.
In principle, if inclined angle alpha is enough big, then the inclination angle of cylinder 3 just is enough to produce the progressive motion in the direction of arrow A of round log 1.But, projection 8 has increased round log advancing in cylinder 3, and has reduced the stress on the inner sleeve 4 of cylinder 3.
When adopting ridge projections 8, the central axis 2 that blade 11 is arranged to further from the inner sleeve surface 4 of cylinder 3 towards cylinder 3 stretches out than ridge projections more than 8, so that when cylinder 3 rotation and round log 1 when leaning against on the ridge projections 8, blade 11 is with regard to the surface of cutting or tearing round log 1, thus the cutting bark.
The operation of cylinder 3 can thus, be cut on round log 1 owing to the effect of blade 11 only based on the round log of being carried out by rotatablely moving of cylinder 1 and the mutual motion of blade 11.But, the efficient of equipment, especially when bark tears stripping, can improve by this way, be that cylinder 3 is arranged to such rotary speed and such path F rotation and moves, this rotary speed is again that the effect that rotatablely moves by cylinder reaches for each independent round log of bunkload processed in cylinder, and this path is, round log will be along with main free-falling with the inner sleeve 4 of cylinder 3 or with the part collision of stretching out from it.The rotary speed of cylinder will be selected so highly, so that act on the sling movement that centrifugal force 2 on the round log 1 produces each round log 1 by what cylinder 3 produced, thus, round log will leap other processed round log, and owing to the collision that the result as the main free-falling of this round log takes place, the power that affacts bark will increase doubly a lot, thus, the tear stripping of bark in cylinder 3 further is enhanced.
Figure 4 and 5 illustrate blade 11 and are fixed on example on the cylinder 3.Formation one is used for the opening 20 of blade 11 on the inner sleeve 4 of cylinder 3.Around opening 20, in the outside of cylinder 3, be welded with a support plate 21, this plate have a corresponding size and with the opening of opening 20 coupling and be used in addition blade 11 hold-down screw 23 do threaded hole 22.

Because this structure, blade 11 can easily be changed by backing out screw 23 from the outside of cylinder 3 simply.
Curve angle of throat sheet 11 shown in the Figure 4 and 5 can turn over 180 ° by backing out (pine) screw 23, thus, can utilize the new piercing portion of cutting edge.
Also can replace a blade 11 with several parallel blades, these blades can all be fixed on the projection 24 of a connection.
Fig. 6 and 7 illustrates an embodiment, and wherein, blade 11 is done by the cutterhead of tooth 30 by one and formed, and above-mentioned cutterhead is arranged to around 31 rotations of its central axis.In this solution, adopt a substrate 32, it can be fixed on the cylinder 3 with the support plate 21 and the screw 23 (not shown in Fig. 6) in the outside that is welded in cylinder 3 shown in Figure 4.
Along the direction of central axis 31, on substrate 32, fix one and do the square ellbeam 33 in a hole.In addition, also fix an overhang bracket 34 on substrate 32, it is perpendicular to central axis 31 and apart from square ellbeam 33 1 segment distances.In the end opposite of square ellbeam 33, detachably fix an end plate 35.
On axle 36, non-rotatably arrange a supporting 39 in a fixed manner and with respect to the hole of square ellbeam 33, thus, the spring 40 that is arranged between supporting 39 and the end plate 35 is arranged to move this axle 36, and will support 39 simultaneously and be pressed against on the blade 11, and further blade 11 is pressed against on the overhang bracket 34.
Done many holes 41 on blade 11, they are arranged on the same circular arc with respect to central axis 31, correspondingly, arrange one or more resilient plunger 42 in supporting 39.This plunger 42 plays a part the positioner of blade 11.When 41 couplings of plunger 42 and hole, belong to plunger 42 ball portion push in the hole 41.
Actual being locked on its operating position of blade 11 are undertaken by the compression stress that is produced by spring 40, and above-mentioned power is pressed against blade 11 on the end plate 34 by supporting 39.
