Abstract

The invention relates to a trunk disc sample bark stripping knife which comprises a knife handle (1) and a knife body (2), wherein a blade (3) is arranged at the front end of the knife body (2), acute-angle-shaped knife points are arranged on the left side and the right side of the blade (3), the front side and the back side of the blade (3) are a long slope and a short slope, and an obtuse-angle-shaped protrusion is arranged on the short slope. A central axis of the knife handle (1) along the length direction and a central axis of the knife body (2) along the length direction are in the same straight line, and are perpendicular to a midpoint with a blade line of the blade (3). The total length of the knife handle (1) and the knife body (2) is only 18cm, and the width of a widest position is only 6cm. The trunk disc sample bark stripping knife is used for stripping bark of a trunk disc sample, and has the advantages of being reasonable in structure, thorough in bark stripping, rapid in bark stripping speed, low in labor intensity and convenient to carry.

Description

The trunk disk sample is taken off dermatotome

Technical field

The present invention relates to a kind of trunk disk sample and take off dermatotome.

Background technology

Carry out that carbon converges and the biomass element task, other obtain the work such as percent of bark about production of forestry practice and scientific research in, (disk sample is the circular discs of the axis intercepting thickness 3-5cm of vertical trunk length direction need to intercept to the trunk of a large amount of normal wood (normal wood is representative trees) a certain amount of disk sample, perhaps the larger trunk of diameter is not intercepted circular discs, the secter pat of intercepting take the trees medulla as the summit), and disk sample is stripped the bark from a tree, obtain bark and timber fresh weight, dry weight.In real work, due to the professional knife that disk sample is not stripped off the skin, chopper can only be used, hatchet strips off the skin to disk sample.It is unprofessional that these use instrument, is difficult for controlling, and uses inconvenience, is unfavorable for work.Disk sample strips off the skin like this and has following problem: (1) strips off the skin not thorough; (2) speed that strips off the skin is slow; (3) labour intensity is large; (4) carry inconvenience.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of trunk disk sample and takes off dermatotome.This trunk disk sample strip off the skin knife structure rationally, strip off the skin thoroughly, the speed that strips off the skin is fast, reduce labor intensity, easy to carry.For solving the problems of the technologies described above, trunk disk sample of the present invention is taken off dermatotome and is comprised handle of a knife, blade, and described blade front end has blade, and two ends, blade left and right are the acute angle shape point of a knife, the blade rear and front end is respectively a long inclined-plane, a short inclined-plane, and an obtuse angle projection is arranged on short inclined-plane.The axis of the axis of handle of a knife length direction and blade length direction point-blank, and with edge line perpendicular to mid point.The total length of handle of a knife and blade only has 18cm, and the widest part only has 6cm.In technique scheme, the axis of the axis of handle of a knife length direction and blade length direction point-blank, such design does not produce component, is conducive to the perforation of power, and is laborsaving.This straight line and edge line are conducive to like this power and concentrate on blade perpendicular to mid point, and purpose is laborsaving, improve the speed that strips off the skin, and reduce labor intensity.Two inclined-planes that are that one is long and the other is short, both sides before and after blade of the present invention, blade long inclined-plane is beneficial to disk sample timber arcuation face and contacts, and is unlikely to blade and directly acts on timber, is convenient to blade and is between bark and timber, is beneficial to strip off the skin; One obtuse angle projection is arranged on short inclined-plane, be convenient to separating of bark and timber.Such being designed with is beneficial to blade and is free between disk sample bark and timber in a word, thereby makes rapid operation, improves quality and the speed of stripping off the skin.The total length of handle of a knife of the present invention and blade only has 18cm, and the widest part only has 6cm, and design can be satisfied the needs that strip off the skin like this, more easily controls during use, is easy to carry simultaneously.

Description of drawings

Fig. 1 is the structural representation that trunk disk sample of the present invention is taken off dermatotome.Fig. 2 is the vertical amplification view of blade that trunk disk sample of the present invention shown in Figure 1 is taken off dermatotome.Fig. 3 is the amplification view that trunk disk sample of the present invention shown in Figure 1 is taken off the blade part A-A line of dermatotome; Enlarged drawing for the A-A line of the blade part of the vertical amplification view of blade shown in Figure 2.

The specific embodiment

As Fig. 1, the trunk disk sample is taken off dermatotome, comprises handle of a knife 1, blade 2.Described blade 2 front ends have blade 3, and blade 3 left and right sides are point of a knife 4.Handle of a knife 1 is connected and is fixed together with blade 2, becomes one, and when being connected and fixed, the axis of the axis of handle of a knife 1 length direction and blade 2 length directions point-blank.Handle of a knife 1 is vertical with the edge line of blade 3 with the formed straight line in the axis of blade 2, perpendicular to the edge line central spot.As Fig. 3 and Fig. 2, the both sides, front and back of blade 3 comprise the long inclined-plane 31 of blade 3 and short inclined-plane 32.Blade has an obtuse angle projection 33 on short inclined-plane 32.As Fig. 1, point of a knife is acute angle shape.As Fig. 1, handle of a knife 1 only has 18cm with the total length of blade 2, and the widest part only has 6cm.During use, the right-hand man all can hold handle of a knife 1 and use.If disk sample is circular discs, just disk sample bark face is stood with suffering, hold from the side on the other hand the disk sample that the bark face stands with suffering, one holds handle of a knife 1, the bark of firmly cutting sth. askew, and cut direction is roughly towards the bark width, cut to timber and get final product, then blade 3 is put into knife-edge part.If the difficulty of putting into, disk sample was fallen, the saw kerf face of disk sample intercepting is landed, dissect several times again along the edge of a knife with a point of a knife 4, and separate the bark of direction that to strip off the skin, then put into blade 3, strip off the skin along the bark length direction, disk sample is pulled down all barks along with the speed of stripping off the skin is constantly rotated, and takes off halfway bark with blade 3 and point of a knife 4 cleanings more afterwards.If disk sample is secter pat, after a straight line (the being fan-shaped radius) face of secter pat intercepting is stood with suffering, can directly put into blade 3 between bark and timber, strip off the skin.
