Abstract

The utility model relates to a girdling knife for grape trees, which is provided with an upper knife rest, a lower knife rest and a knife shaft, wherein the upper knife rest and the lower knife rest rotate around the knife shaft into the shape of a pair of scissors, and two blades are arranged at the end of either the upper knife rest or the lower knife rest so as to form blade groups in pairwise correspondence; the blade groups are arranged on the same plane, and a gap is formed between the two blade groups; an adjusting shaft hole capable of adjusting a girdling diameter is arranged on the lower knife rest, the blades are respectively fixed on the upper knife rest and the lower knife rest by blade clamps and fixing screws, and the cutting edge of each blade inclines into a curve from outside to inside. A peel-shoveling knife is attached to the girdling knife, and a fork shovel knife is arranged on the girdling knife. Compared with a common blade, the utility model improves the work efficiency by more than 10 times and can have higher work efficiency by combining two persons or more to realize one-person girdling and one-person pinch spalling or multi-person pinch spalling.

Description

Vine band girdle cutter

Technical field the utility model belongs to a kind of vine band girdle cutter of controlling the long-living and nutrient supply of grape.

Band girdle in the existing viticulture process of background technology claims ringing again, is a kind of in the basic trimming method of fruit tree.It is with band girdle device or sharp blade the epidermis (phloem) of limb to be peelled off a circle, thereby the synthetic nutriment in temporary transient top interruptedly transports downwards, promote the accumulation of acrial part carbohydrate, reduce the absorption function of root system, suppress the growth of root system, and then play and suppress to nourish and grow, promote to become flower and improve fruit-setting rate, the method for premature ripening.

Existing band girdle instrument is blade mostly, along two circumference ring cutting one circles at a distance of about 1-2cm of grape branch rattan, the skin between the circumference is peelled off again.Because branch rattan viny is various, for large-scale vineyard, such workload is huge, and too low by this mode work efficiency, working strength of workers is too big.

The Chinese patent that on August 28th, 1991 is disclosed, publication number is CN2083405U " four sword band girdle cuttves " has two blade, can once cut out the twice contour, can improve work efficiency for addressing the above problem.But it is exactly can not adapt to for the thicker fruit tree branch rattan of diameter that there is a problem in this patent, and whenever running into this situation, the also handy blade of orchard workers solves according to old way.

The summary of the invention the purpose of this utility model to propose exactly a kind of can a ring cutting twice contour, and can regulate the vine band girdle cutter of encircling diameter, overcome the deficiencies in the prior art with this.

This vine band girdle cutter that the utility model proposes, it has upper tool post, lower slide, cutter shaft, upper tool post and lower slide all rotate around cutter shaft, become the scissors shape, the termination that it is characterized in that upper tool post and lower slide respectively has two blades to form corresponding in twos set of blades, each set of blades is all in same plane, and is gapped between two set of blades, has on the lower slide and can regulate the adjustable axis hole of encircling diameter.

Blade is fixed on upper tool post and the lower slide by blade folder and hold-down screw, and the cutting edge of every blade is from tilting outside to inside.

Blade cutting edge is the curve cutting edge.

Adjustable axis hole is the circular hole that is connected by a rectangular channel.

Cutter shaft is the bolt that nut is arranged.

The band girdle cutter has a fork perching knife with a shovel dermatotome on the shovel dermatotome.

Use of the present utility model is such, the grape branch rattan of need peeling is clamped gently, and palm is held the handle end of lower slide, rotates about 1/4th circles, can form the two circle cut channels of the about 2cm of spacing, it is complete operation that bast between two circle cut channels is scalped.When running into thick branch rattan the cutter shaft nut is unclamped, push another axis hole of lower slide to cutter shaft and entangle, tighten nut again and can enlarge the diameter of encircling of going up lower slide, just can realize the band girdle of thick branch rattan by last method operation.

For more effective bast between two cut channels is scalped, the utility model is subsidiary to have designed an annex, promptly shovels dermatotome.The shovel dermatotome is to add fork perching knife that about 1cm is wide of weldering on the basis of normal screws cutter.There is cutting edge the perching knife end.

Certainly, also the bast pinch spalling can be gone with ordinary blade.

The utility model is compared work efficiency and has been improved 10 times and also go up with the ordinary blade peeling, if two people or many people combination can realize people's ring cutting, and a people or many people pinch spalling, work efficiency is higher.

Description of drawings Fig. 1 is the utility model front view.

Fig. 2 is the utility model vertical view.

Fig. 3 is the A-A profile.Fig. 4 is a shovel dermatotome front view.

Among Fig. 1-4, each parts label is as follows:

The 1-upper tool post; The 2-lower slide; The adjustable axis hole of 3-; The 4-cutter shaft; The 5-blade; 6-blade folder; The 7-hold-down screw; 8-shovels dermatotome; 9-pitches perching knife.

Embodiment as Figure 1-3.Upper tool post (1), lower slide (2) shape and common scissors or pliers approximate substantially, and upper tool post and lower slide be the symmetry structure, can transposition.This example is opened two axis holes on lower slide, middle with the straight trough connection, about spacing 1-2cm forms adjustable axis hole (3) between two circular holes.The head end of upper tool post and lower slide is respectively opened two apertures, and four blades (5) are fixedly got on blade folder (6) and hold-down screw (7).The thickness of blade and blade folder is approximately 2mm.As mentioned above, four blades form two corresponding in twos set of blades.Each is made up of each set of blades a cutter and bottom knife, and blade cutting edge all slopes inwardly, and the cutting edge line remains in the same plane, and the distance between two groups of blades is 2cm.The cutting edge of blade is a sickle shaped, and curvature is arranged, so that do not slide when encircling rattan.Blade can unload when blunt polish again sharp.NM parts as mentioned above.

The band girdle cutter length overall 170mm that this is routine, the wide 50mm when closed, thick 26mm makes with steel, the about 300g of gross weight.Shovel dermatotome (8) is to make with a common flat screwdriver as shown in Figure 4, adds to weld the fork broach (9) that 1cm is wide on knife bar, and to be used effect better with circular cutter.But use the ordinary blade pinch spalling, do not influence the effect of circular cutter.As an annex, the shovel dermatotome is omissible.

This routine band girdle cutter is on probation through certain vineyard, and ring cutting effect spy is good, and work efficiency is more than 12 times of blade ring cutting.
