Description
Technical Field
[0001] The utility model relates to a ring barker, in particular to a peach tree ring barker, belonging to peach tree pruning tools. Background Art
[0002] A peach tree girdler is a tool used to gird peach trees. Girdling involves removing a ring of bark from a specific area of a tree's trunk. In fruit tree cultivation, proper girdling can regulate nutrient distribution within the tree. For example, girdling a fruit tree's trunk can prevent organic nutrients produced by the leaves from being transported downward through the phloem of the bark, allowing more nutrients to accumulate above the ring opening. This promotes fruit growth and development, improving fruit set and quality.
[0003] It generally has a relatively sharp blade, which is convenient for cutting the bark neatly, and some designs will consider minimizing damage to the tree's xylem, because the xylem is mainly responsible for the transportation of water and minerals. Once excessively damaged, it will affect the growth of the tree and even cause the death of the tree.
[0004] In the past, when peach trees were ring-barked and girdled in the summer, wallpaper knives were generally used, which often caused damage to the bark and even the bone part of the tree. During the ring-barking and girdling process, the peach trees would also cause gum flow, which caused great damage to the trees and was not conducive to operation. How to avoid these problems is a matter of great concern to Taoyuan technicians. Summary of the Invention
[0005] In view of the problems that peach tree ringing and girdling processes may cause damage to the bark and even the bone part of the tree, and may also cause gum flow in the peach tree, the utility model provides a peach tree ringer, the purpose of which is to reduce the damage to the tree branches and reduce gum flow.

The limiting keys of the pair of limiting blocks are respectively located in the pair of axial grooves;
[0009] Further, the circular cutter two is relatively arranged in the hook part directly below the circular cutter one through a lower cutter holder. The circular cutter one and the circular cutter two are arranged on the same horizontal plane in the vertical direction through the hinge shafts on their respective cutter holders;
[0010] Further, the cutting edge of the girdling knife faces the side of the cutting edge of the circular cutter one. The width of the cutting edge of the girdling knife has multiple types;
[0011] Further, the cutting knife includes a cutting knife handle. A flange is arranged on the upper surface of the horizontal part of the "C" - shaped structure. An annular groove is arranged on the lower surface of the horizontal part of the "C" - shaped structure. An open - ring spring is arranged in the annular groove;
[0012] Further, a plurality of limiting card slots are arranged on the opposite side of the rack on the girdling knife rod. A rotating limiting card is arranged above the horizontal part of the "C" - shaped structure.

When using the first circular cutting knife and the second circular cutting knife to cut the first knife on the outer circumference of the tree branch, the cutting edge of the ring - barking knife is lifted to the side close to the center of the first circular cutting knife to prevent the ring - barking knife from cutting the tree bark. Then, according to the required width, it is displaced a certain width on the tree trunk. After displacement, the cutting edge of the ring - barking knife is located between the first cut and the second cut. When performing the second cutting, the ring - barking knife needs to be adjusted to the ring - barking thickness position to perform ring - barking on the tree bark. By equipping ring - barking knives with different widths of cutting edges, tools that can ring - bark the tree bark at one time can be used according to the ring - barking width.
