Abstract

The utility model discloses a circular debarking knife for fruit tree belongs to fruit tree dressing tool, aim at providing that a convenient operation is laborsaving, efficient, the ring is shelled fruit tree ring of high quality and is shelled the instrument. It includes handle of a knife and blade, handle of a knife (1) is the annular slab structure of semicircle, and the lower terminal surface of this handle of a knife has the blade to take in groove (4), and establish in the groove is taken in to this blade through the round pin axle blade (3) that are the sickle shaped structure, the lower terminal surface of handle of a knife (1) is fixed with gyro wheel (5). The utility model discloses a can form the circular arc that is similar to the trunk between handle of a knife and the blade, consequently can avoid the circular cutting mouth to take place the incline, and the increase gyro wheel can reduce the friction between handle of a knife and the trunk, reaches the purpose of rapid operation. That specialized tool is shelled to planting fruit -trees ring.

Description

Fruit-tree girdling knife

Technical field

The utility model relates to a planting fruit-trees dressing tool, particularly relates to a kind of fruit-tree girdling knife; Belong to farm implements.

Background technology

Band girdle the phloem that its trunk or major branch are done is peelled off a ring, peeling and do not injure a kind of planting fruit trees technique of xylem within the fruit tree growth phase; Object is that the carbohydrate blocking blade generation is carried to root system by epidermis, makes it to accumulate to promote that young sprout is aging on twig, suppresses winter tip rudiment, effectively promote flower bud differentiation, one-tenthization and bear fruit.At present, the general perching knife that adopts carries out band girdle process to limb, not only labour intensity and operation easier is large, efficiency is low, and is difficult to control ring-peeling depth; Easily damage is caused to the xylem of fruit tree, finally affect abloom rate, fruit-setting rate, the fruit yield and quality of fruit tree.In addition, adopt perching knife band girdle, the easy deflection in ring cutting direction, rings cut are more crude, are unfavorable for stripping mouth healing growth.

Summary of the invention

In view of the foregoing defects the prior art has, the utility model aim to provide a kind of easy to operate, efficiency is high, the measured fruit-tree girdling knife of band girdle matter.

To achieve these goals, the utility model by the following technical solutions: it comprises handle of a knife and blade; Handle of a knife is the slab structure of semi-annular shape, and there is blade accommodating groove the lower surface of this handle of a knife, and the blade in sickle shaped structure is located in this blade accommodating groove by bearing pin; The lower surface of handle of a knife is fixed with roller.

Handle of a knife be each side fixed with holding rod.

Compared with the prior art, the utility model, owing to have employed technique scheme, has changed handle of a knife into semicircular ring plate like structure, and have employed falculate blade structure; Therefore can form the circular arc being similar to trunk between handle of a knife and blade, thus rings cut generation deflection can be avoided.Because the lower surface at handle of a knife adds roller, therefore, it is possible to reduce the friction between handle of a knife and trunk, rapid operation is convenient.3rd, because the both sides at handle of a knife add holding rod, therefore can avoid causing Girding cutter slippage because of perspiration.4th, owing to adding blade accommodating groove on handle of a knife, therefore can eliminate blade and expose and the hidden danger that causes personal injury, be convenient to collection.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the vertical view in Fig. 1.

In figure: handle of a knife 1, holding rod 2, blade 3, blade accommodating groove 4, roller 5.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:

As shown in Fig. 1 ~ 2: the slab structure of handle of a knife 1 in semi-annular shape, there is blade accommodating groove 4 lower surface of this handle of a knife, and the blade 3 in sickle shaped structure is located in this blade accommodating groove by bearing pin (not indicating in figure); The lower surface of handle of a knife 1 is fixed with roller 5.

For the ease of grasping, be each side fixed with holding rod 2 at handle of a knife 1.
