Be used for to the round log bark or to round log prepare in case carry out separately bark-particularly for the round log that is difficult to bark-equipment illustrate as schematic perspective at Fig. 1.This equipment illustrates from this 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 illustrates the cutaway view along the III-III line of Fig. 2.
This equipment comprises a cylinder 3 around its central axis 2 rotations, and pending round log 1 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 a position that tilts 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 the device of reference number 13 representatives of applying greatly, 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 accompanying drawing, omit.
Form an inner member 5 in cylinder 3, it can fix or be adjusted to desired position.Member 5 is arranged to extend to the desired zone of cylinder 3, in other words, along the whole length of cylinder or just extend, and be arranged to the space segmentation that the cylinder-shaped inner sleeve 4 by cylinder 3 limits along the part of its length be special-purpose processing space 6 and be retained in space 7 outside it.So, through the round log 1 of cylinder 3 feedings just via above-mentioned processing space 6 cylinder 3 of passing by.Like this, handle space 6 and comprise that one is positioned at the passage at both ends open of cylinder 3, the inner sleeve surface of this passage is formed by the wall 17 of entity on the one hand, the part of inner sleeve 4 at above-mentioned wall place by the rotation of cylinder 3 forms on the other hand, and this wall 17 is formed by the inner member 5 that is adjusted to desired position.
Relative motion between the inner sleeve 4 of round log 1 and cylinder 3 can change by the position that changes inner member 5.
As being clear that in Fig. 1 and 3, inner member 5 is arranged to central axis 2 rotations around cylinder 3.Inner member 5 can not be mounted to yet and rotate with respect to cylinder.In order to rotate, inner member 5 supports with the spring bearing on suitable beam 14 and the framework at equipment 16 at two ends.As being clear that among Fig. 3, inner member 5 usefulness one actuator 15 is locked on its normal position that is formed by its actual operational position.The end that pulls spring that for example may comprise of actuator 15 is fixed on the framework 14 of entity, and the other end then is fixed on the inner member 5.
In one embodiment, inner member 5 is arranged to when having a masterpiece that surpasses predetermined force to be used on the inner member 5, from its operating position or normal position turn-off, and, correspondingly, when the above-mentioned power that surpasses predetermined force fails, be back to its normal position.If in the slit 9 of the bark wedge of timber between the inner member 5 of cylinder 3 that rotates in the direction of arrow B and inner sleeve 4, this power will produce, this means, because the damage that causes that chokes suddenly of cylinder 3 and inner member 5 can reduce or avoid fully.
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, this projection is twined by the mode that spiral changes with respect to the central axis of cylinder.In the example that cylinder shown in Figure 13 is arranged to rotate in the direction of arrow B, ridge projections 8 forms the winding of dextrorotation.In the case, the discharge end at cylinder 3 of rotatablely moving of cylinder 3 is leaning against on the round log 1 on the projection 8 and is producing a power, that is to say, produces the power along the direction of the arrow A of Fig. 2.
In principle, if inclined angle alpha is enough big, then the inclined angle alpha 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 strengthened round log advancing in cylinder 3, and has reduced the stress on the inner sleeve 4 of cylinder 3.
When adopting ridge projections 8, blade 11 is arranged to further from the surface of the inner sleeve 4 of cylinder 3 that the central axis 2 towards cylinder 3 stretches out than spinal apophysis 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 shape of the wall 17 that is formed by inner member 5 is so done the beak structure 18 of a wedge-like of imaging in the lower end, so that rotatablely moving of cylinder 3 will force round log 1 by inner sleeve 4 guiding of the wall 17 of inner member 5 and cylinder 3 time, move along the mode shown in the arrow C among Fig. 3.Between the inner sleeve 4 of the wedge-like beak structure 18 of above-mentioned inner member 5 and cylinder, provide a slit 9, to be used for from handling space 6 to the space of the opposition side of the wall 17 of inner member 57 discharging barks.The size of slit 9 will be made and make its side expansion towards above-mentioned free space 7, and this helps bark through slit 97 dischargings towards the space.
Arrange a bark space 10 in space 7, bark discharges automatically from this space 10 usefulness, one unshowned device.Another kind of scheme is, bark by the effect that rotatablely moves of cylinder 3 and simultaneously the cylinder 3 of effect inclination and/or be arranged on spirality projection 8 on the inner surface of cylinder 3, from 10 discharges of above-mentioned space.
In example shown in Figure 3, cylinder 3 in principle can be along the direction rotation opposite with arrow B, and in this case, the motion of round log 1 also will be along the direction opposite with arrow C.In the case, bark can not be discharged through slit 9, but can only mainly discharge from discharge end by the two ends of cylinder 3, and/or discharges through the bark opening (not shown) in the sleeve.
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 for blade 11 hold-down screw 23 do threaded hole 22.Blade 11 is welded on the projection 24, and this projection is connected with an installing plate 25 again.Installing plate is fixed on the support plate 21 with screw 23.In order to make blade 11 have the projection amount a from the surface of inner sleeve 4 of requirement, the Board for adjusting vision distance 26 of requested number is housed between support plate 21 and installing plate 25.Because this structure, blade can easily be changed from the outside of cylinder 3.
