Description
Technical field
The present invention relates to a kind of cutter sweep, particularly the chaindriven saw cutting device of one.
Background technology
In prior art, there are a kind of oily chain saw for lumbering or electric chain saw, its structure mainly comprises main frame, main frame is provided with output chain gear, and main frame front end is also fixed with guide plate, and guide plate outer end is provided with driven sprocket, sawing chain has been installed around between output chain gear and driven sprocket, sawing chain is interval with cutting, and guide plate is provided with gathering sill, and gathering sill is used for leading to sawing chain.This device is for sawing tree, and therefore the thickness of its sawing chain is thin, and bearing strength is low.
In prior art, also has a kind of disk chain saw, its structure mainly comprises main frame, main frame is provided with output chain gear, and main frame front end is also fixed with driven pulley support, and the outer end of driven pulley support is provided with driven sprocket, driving chain has been installed around between output chain gear and driven sprocket, driven sprocket through-drive is connected with circular saw bit, and circular saw bit can be single saw blade, also can be two coupling saw blades that contrary rotates.The chain of general this circular saw is comparatively thick, and intensity is larger.
Above-mentioned two kinds are gone saw cutting device structure similar, its main frame can be general, due to the difference of sawing chain and this body structure of driving chain, causes the structure of output chain gear also not identical, that is by changing respective sprocket and other supplementary structures, main frame just can be made general.But, the fact is really not so, reason is: output chain gear long-term work is under shock loading, output chain gear is easily caused to get loose, in order to ensure that output chain gear is fixing reliable, when output chain gear is installed, first be locked on output shaft with nut with certain pretightning force, then with solid seal glue, nut and thread pitch and thread groove are filled up, after solid seal glue solidification, can ensure that output chain gear connects reliable.This mounting means, only just can complete in manufacturer, and user can not complete, if user directly changes, not only its pretightning force can not reach standard, and sealing operation is also that user can not complete.This technical barrier annoyings the manufacturer of chain saw always, and for a long time, never producer can be general by main frame, and its basic reason is that client cannot self-changeable output chain gear exactly.And both are general, it is necessary for changing output chain gear, because manufacturer produces in this way; This has become a kind of thinking set, a kind of technology prejudice.
Summary of the invention
The object of this invention is to provide the multi-functional chain saw of one that can overcome above-mentioned technology prejudice, making it when not changing output chain gear, timber cutting chain saw can be converted to from circular saw.
The object of the present invention is achieved like this: a kind of multi-functional chain saw, comprise main frame, main frame is provided with output chain gear, main frame front end is also fixed with driven pulley support, the outer end of driven pulley support is provided with driven sprocket, driving chain has been installed around between output chain gear and driven sprocket, driven sprocket through-drive is connected with circular saw bit, described driving chain is through some tooth plates, bearing pin and carrier bar are formed by connecting, tooth plate is roughly triangular in shape, it is arc transition between the leg-of-mutton limit of tooth plate and limit, each tooth plate and carrier bar are equipped with two pin-and-holes, bearing pin one_to_one corresponding inserts in pin-and-hole, described tooth plate is positioned at middle part, carrier bar be symmetrically distributed in tooth plate two outside, the carrier bar of the every side of tooth plate has three layers at least, the carrier bar of innermost layer is connected across between adjacent tooth plate, the carrier bar of outer one deck is connected across between adjacent two carrier bars of interior one deck, described output chain gear and driven sprocket comprise a discoid body, and the periphery of body is provided with some teeth groove extended in body, described teeth groove and tooth plate suitable.
When the present invention works, drive tooth plate motion by teeth groove, tooth plate drives carrier bar motion, thus realizes driving driven sprocket to rotate, and then drives circular saw bit circumgyration incision.This device, can greatly be gained in strength because carrier bar has multilayer as circular saw, therefore, can ensure that driving chain has enough intensity driver plate saw blades and cuts.When needs convert timber cutting chain saw to, change driving chain and driven pulley support, can convert device to timber cutting chain saw, both output chain gears are shared.In this device, by the peculiar structural design of driving chain, make output chain gear can be general, so just make user can parts beyond self-changeable main frame and output chain gear, switch between circular saw and timber cutting chain saw, realize a tractor serves several purposes.Compared with prior art, the present invention looks for another way, and overcomes the technology prejudice in industry, and it does not need to change output chain gear, does not destroy, device can be switched between circular saw and timber cutting chain saw, be very easy to user sealing.
As a further improvement on the present invention, described teeth groove is positioned at the middle part on body thickness direction.When tooth plate engagement enters teeth groove, there is blocking of body part tooth plate side, and make tooth plate working stability reliable, bearing capacity is large.
Reliable for ensureing that carrier bar connects, being interference fit between the carrier bar of outermost one deck and bearing pin, is matched in clearance between all the other each layer carrier bar and bearing pins.Can ensure that each layer carrier bar can reliably be fixed on bearing pin like this, not affect the relative motion of each layer carrier bar simultaneously.
As a further improvement on the present invention, described circular saw bit comprises two coupling saw blades that contrary rotates.Adopt two saw-blade structure, may be used for cutting metal material; When a saw blade is only installed, can cutting stone material.
