Description

Wood processing machinery

Technical field

The present invention relates to a kind of as described in the preamble especially with the yule logs processing equipment of firewood circular saw form by claim 1.

Background technology

In firewood circular saw commonly used now, outlet is set like this, makes sawdust fall down by the protection housing down.This is portable, as long as firewood circular saw is the agricultural machinery that can set up out of doors.But during no longer be this situation.Firewood circular saw is also used in private housework during this time, and the sawdust of discharging down is counted as interfering fully there.

Summary of the invention

Therefore setting out thus the objective of the invention is, and improves device by the described type of beginning like this with simple and cheap measure, makes stopping ring environment pollution to a great extent.

This purpose solves in combination by the feature of claim 1 characteristic and the feature of preamble.

The outlet that is provided with in the zone below the narrow side of the back of protecting housing is positioned in an advantageous manner on the discharge direction of the sawdust of saw blade generation and acceleration, obtains the automatic glitch-free loading of retracting device.Can constitute the sawdust collection container simply in an advantageous manner at this this retracting device.When replacing ground application pumping equipment, satisfy less suction force with advantageous manner.

The favourable structure of upper measure and suitable further expansion are described in the dependent claims.Retracting device can comprise the sawdust collection container, and this sawdust wall of a container is breathed freely on its surperficial part at least.This container sometimes is drained, and this allows the simple and clean recovery of sawdust.

The sawdust collection container comprises the preferred sack with the filter bag form that at least one is made of ventilative material at least in part aptly.Therefore also keep more tiny dust in an advantageous manner here.

The sack that constitutes the sawdust collection container sets a deploying device aptly, preferably fully keeps at least opening wide in its open area by this deploying device sack.Therefore can avoid the obstruction of sawdust.

The further expansion of another of upper measure can be, an outlet connection that is equipped on outlet is connected on the protection housing, the sawdust container or selectively the flexible pipe of aspirator can be connected on this outlet connection.This structure allows different ways of recycling.

Describe other the favourable structures of upper measure and suitable further expansion in the dependent claims and can at length draw by means of accompanying drawing by following example explanation.

The specific embodiment

Firewood circular saw based on Fig. 1 to 4 constitutes according to dimension saw principle (Wipps  genprinzip).Firewood circular saw comprises one and is the frame 1 of truncated pyramid at this, at axle 2 of this frame upper support, this one side and the CD-ROM drive motor acting in conjunction of not describing in detail and support a dish type on the other hand the saw blade 3 of (flankieren) frame 1 at a gusset.Saw blade 3 sets one and constitutes the feed arrangement of swing arm at this.This feed arrangement comprises a swing frame 4 that is bearing in pivotally on the frame 1, and this swing frame comprises one and be configured for the annex that holds passage 5 of (S  ggut).

Saw blade 3 sets a protection housing.This protection housing comprises one and is fixedly installed on bottom 6 on the frame 1 and one and jointly limits one towards the feed mechanism top 7 of unlimited working clearance with bottom 6 in the embodiment that describes; the following zone of saw blade 3 is embedded in this bottom 6, and this top surrounds top portion's section of saw blade 3.Top 7 is provided with up pivotally for the clean throat width that increases the working clearance aptly.

Constitute up in the zone in its lower section, bottom 6 of the chest that opens wide and be provided with an outlet 8, enter into by saw blade 3 box-shaped bottom 6 air and can leave by this outlet by the sawdust that this air imports together.The bottom 6 of box-shaped constitutes by two sidewalls round saw blade 3, and described sidewall is connected to each other by the narrower shell that surrounds except top opening.Therefore this shell constitutes a narrower rear wall 9 on away from the side of feed mechanism.The following shortening portion that outlet 8 constitutes rear wall 9, this rear wall is with the end of bottom 10 partition distance ground or correspondingly make groove (ausnehmen).Based on reliability, separator lined is passed through in outlet 8.Bottom 10 constitutes towards outlet 8 with descending.

The sawdust that is produced by yule logs when cutting in order to be recovered in is provided with a retracting device, and its inner space is communicated with by the inner space of outlet 8 with the top 6 of box-shaped.Retracting device can comprise a sawdust collection container, and its wall is breathed freely at least in part, and making can leadage air and keep sawdust here.

The sawdust collection container constitutes sack 11 in based on the embodiment of Fig. 1, and this sack sets a deploying device.This deploying device constitutes like this, makes that sack especially fully keeps opening wide at least in part in its open area.Described deploying device comprises the framework 12a of a knuckle in the open area that is embedded into sack 11 in describing embodiment, its following arm can be suspended on the hook 13 of bottom side of the chest that constitutes bottom 6 and its top arm can be locked by a retaining mechanism (be the form of off the hook (Fallhaken) 14 at this) that is arranged on the rear wall 9.Stretch out one at this backwards by framework 12a and support bow 12b, this support bow is in this is embedded into sack 11 and make this sack strut on its whole length.The bow of an overlap joint sack 11 can certainly be set selectively, on this bow, hang sack.

Sack 11 is moved to simply with its edge of opening zone in the embodiment that describes on the bight that comprises below chest outlet 8, that constitute bottom 6 and by the ring on the fixture that can be hanging to the chest side 15 and is fixed on the chest that constitutes bottom 6.Sack 11 can certainly be provided with a flange connector selectively, and it can be inserted on the following chest bight that comprises outlet 8 and preferably can be fixed in this.

In form of implementation, be provided with a sawdust collection container 16 that constitutes the small basket of sealing by Fig. 2.It comprises the flange connector 17 on the following bight that comprises outlet 8 of a bottom 6 that can be inserted into box-shaped.Small basket 16 can comprise a truss-like support 18 that constitutes by bar connected to one another aptly, holds one from the textural sack 19 that adapts to the inner space of encirclement in therein, and it can be connected with flange connector 17 aptly.

In the embodiment based on Fig. 3 and 4, an outlet connection 20 that is equipped on outlet 8 is connected on the bottom 6 of box-shaped.This outlet connection is installed on the adapter 21, and this adapter surrounds on the rear wall 9 of bottom 6 that outlet 8 ground are arranged on box-shaped.On outlet connection 20, can connect a sawdust collection container or pumping equipment selectively.

In the embodiment based on Fig. 3, a sack 22 is connected on the outlet connection 20.This sack detachably is fixed on to connect by means of a tightening hoop 23 with its edge of opening zone and takes on 20.Sack 22 sets a deploying device 12 again.This deploying device comprises one at this can be contained in bow on the supporting hook that is fit to that constitutes the chest of protecting lower housing portion 6, overlap joint sack 22, and sack 22 is suspended on this bow by suspension ring 24 grades.

Sack 22 makes it have the bottom contact under open state in this such design size, and this can make deploying device 12 unloadings.This is also effective for each above-mentioned embodiment.Effective equally for structure as the sack of filter bag.In order to constitute the material that sack 11 or 19 or 22 adopts weaving aptly, this material be basically to dust seal but ventilative.Can relate to textile material and/or filtering material such as felt at this.

By means of clamping ring 23 suction hose 25 is set in by the form of implementation of Fig. 4 on outlet connection 20, it leads to a blower fan of not describing in detail.
