Description
Technical field
The present invention relates to log debarking device and bark knife, particularly the floating type bark knife in the ring type apparatus for peeling off.
Technical background
The residue specifications such as the small diameter grade that fell in the forest zone, intermediate cutting produces and short material are many, quantity is large, have a very wide distribution.At present, usually adopting ring barker to carry out peeling to it processes.And the bark knife on peeling machine exists the problems such as the peeling rate is low, of poor quality, cutting edge wearing and tearing rust is fast when carrying out the curved larger small diameter grade timber of marrow.Therefore, the technical problem of the problem of solution bark knife Fast Wearing, reduction tool change time, the service life of improving bark knife, the curved log debarking quality of raising marrow is the key that improves small diameter grade material peeling quality.
At present, do not exist and to realize characteristic bark knife of the present invention, in this device, by screw and nut, blade and tool arm are clamped, this mode helps to shorten tool change time, improves greatly the peeling quality of the curved material of marrow, and this makes the present invention be different from prior art.
Summary of the invention
The technical problem to be solved in the present invention is, when carrying out peeling on bark peeling machine, the curved larger small diameter grade timber peeling rate of marrow is low, bark knife wearing and tearing rust is fast, bark knife service life short and bark knife loading and unloading reconditioning trouble problem.And provide a kind of marrow curved small dimension wood bark knife, its advantage is to be fit to the curved timber of marrow is carried out effective peeling, blade exchange fast, easily, and blade can protect toothholder to avoid wearing and tearing, and the blade long service life, and then the service life of having improved bark knife.
technical solution of the present invention is: the curved small dimension wood bark knife of a kind of marrow, comprise that tool arm (1) and blade (2) consist of, it is characterized in that, described tool arm (1) floating end is processed with toothholder (3), blade (2) is arranged on toothholder (3) by screw (7) and nut (8) locking, described blade (2) is processed with two cutting edges (4, 4 '), and blade (2) back side is to be processed with mounting groove (9) above an installation convex surface (5) reaches, described installation convex surface (5) is made circular arc around dead axle (11), dead axle (11) is parallel to the direction of feed of log, described toothholder (3) surface is to be processed with on an installation concave surface (6) and toothholder (3) through hole (10) is installed, described toothholder (3) is installed concave surface (6) and is made circular arc around dead axle (11), dead axle (11) is parallel to the direction of feed of log.
As further improvement, described blade (2) is processed with two cutting edges (4,4 '), after one of them cutting edge wearing and tearing rust, can use the another one cutting edge to carry out peeling by the Rotate 180 degree, and it helps to improve the service life of blade.
As further improvement, the installation convex surface of described blade (2) is keel-shaped, have two faces (12 at least, 12 ') make circular arc around dead axle (11), and intersect at angle on the two sides, center at blade (2) forms one " ridge " (13), and its perpendicular direction is in the log direction of feed.This technical scheme, can guarantee blade on toothholder accurately the location.
As further improvement, respectively there is a ridge (14,14 ') on described blade (2) both sides, and its perpendicular direction is in the direction of feed of log.This technical scheme helps to protect toothholder limit section to avoid wearing and tearing in working angles, guarantees that the dimensional accuracy of toothholder is constant.
As further improvement, the installation concave surface of described toothholder (3) is triangular groove (17), have two faces (16 at least, 16 ') make circular arc around dead axle (11), and intersect at angle on the two sides, center at toothholder (3) forms " V " type groove, and its perpendicular direction is in the log direction of feed.This technical scheme helps blade (2) protection toothholder (3) to avoid wearing and tearing and accurate positioning.
Technique effect of the present invention is: simple in structure, easy to use, can be applied in the peeling of the curved material of various marrows, and improve the peeling quality.
