Description

Technical Field

[0001] The invention relates to a fruit tree ring-barking device, in particular to a fruit tree ring-barking device with adjustable opening diameter and ring-barking width. Background Art

[0002] In the cultivation of fruit trees like grapes and kiwifruit, the quality and yield of the fruit are influenced by a variety of factors, with nutrient distribution within the tree being a key factor. Traditional cultivation techniques often lack precise control over nutrient distribution within the tree, resulting in inconsistent fruit quality and difficulty achieving ideal yields.

[0003] As an agricultural technique, ring barking has been widely used in fruit tree cultivation. By ring barking, the downward transport of nutrients from the tree can be blocked, the nutrient assimilation of organs above the ring barking mouth and the accumulation of plant endogenous hormones can be increased, thereby promoting the growth and development of fruits. However, the existing ring barking technology lacks flexible ring barking tools. Improper operation may cause the ring barking mouth to be too wide, affecting the tree's nutrient transport and recovery, and even causing the tree to weaken or die. The ring barking is too narrow and does not achieve the desired effect. In addition, continuous ring barking or excessive ring barking may cause the tree to weaken, reducing the resistance and yield of the fruit tree. These factors lead to unstable ring barking effects and may even cause damage to the tree.

[0004] There are several types of girdling tools currently on the market, including girdling rings, girdling chains, and girdling pliers. Simpler girdling tools, such as girdling rings and girdling chains, are suitable for trunks or branches of varying thicknesses. However, they are difficult to control the force and depth during operation, and may accidentally injure the xylem, which not only affects the girdling effect but also has an adverse effect on the overall growth of the tree. Existing girdling pliers are more ideal for controlling the force and depth of girdling than girdling rings and girdling chains, but they have requirements for the thickness of the trunk or branch. A trunk or branch that is too thick cannot be girdled due to the limitations of the opening diameter of the girdling pliers. Furthermore, the girdling width of most existing girdling tools is fixed, and the width cannot be adjusted according to the trunk diameter of the plant. This may result in the girdling being too wide or too narrow, affecting the girdling effect. If the girdling opening is too wide, it may lead to poor growth or even dead trees, while if the girdling opening is too narrow, the effect of promoting early maturity is poor.

[0005] Therefore, developing a scientific and reasonable ring-barking device with adjustable opening diameter and ring-barking width is of great significance for improving the fruit quality of kiwifruit, grapes and other fruit trees. Summary of the Invention

[0006] The purpose of the present invention is to provide a fruit tree ring-barking device with adjustable opening diameter and ring-barking width, which can achieve precise control of tree nutrient distribution through precise ring-barking operation and standardized operation process, thereby improving the quality of the fruit.

[0007] To achieve the above objectives, the specific plan is as follows:

[0008] A fruit tree ring-barking device with adjustable opening diameter and ring-barking width comprises a fixed ring-barking part, a movable ring-barking part and clamp handles arranged at the ends of the fixed ring-barking part and the movable ring-barking part. The fixed ring-barking part is provided with a multi-stage adjustable shaft hole, and a clamp shaft is provided in the shaft hole. After the movable ring-barking part is connected to the clamp shaft, a rotatable connection with the fixed ring-barking part is achieved; the fixed ring-barking part and the movable ring-barking part are both provided with double-layer ring-barking blades, and the surface of the double-layer ring-barking blades is respectively provided with three circular screw holes and a rectangular hole, and a gasket and a skin scraping inner knife are provided in the interlayer, the gasket is coaxially arranged with the circular screw hole, and the skin scraping inner knife is embedded in the rectangular hole.

[0009] Furthermore, the double-layer ring-barking blade includes a movable blade and a fixed blade, the fixed blade is integrated with the fixed ring-barking piece or the movable ring-barking piece, and the movable blade is detachably fixed to the fixed ring-barking piece or the movable ring-barking piece by screws and nuts a.

[0010] Furthermore, a step is integrally provided at the tail of the movable blade, and the height of the step is 2 mm (for a movable blade with a ring-peeling width of 5 mm) or 4 mm (for a movable blade with a ring-peeling width of 7 mm).

[0011] Furthermore, after the screw is passed through the circular hole, the movable blade is fixed to the fixed ring stripping piece or the movable ring stripping piece using a nut, thereby forming a double-layer ring stripping blade.

[0012] Furthermore, a skin-scraping tip is provided on the top of the fixed blade of the fixed ring-stripping piece.

[0013] Furthermore, the cutting edge of the double-layer ring-barking knife is inclined from outside to inside to form a curved cutting edge.

[0014] Furthermore, the length of one side of the scraper inner knife embedded in the rectangular hole is fixed, and the height of the blade side of the scraper inner knife is 3mm, 5mm or 7mm respectively; the height of the gasket is adapted to the scraper inner knife, and its height is 3mm, 5mm or 7mm respectively.

[0015] Furthermore, the opening diameter can be adjusted by adjusting the clamp shaft to different shaft holes.

[0016] In summary, the present invention has the following beneficial effects compared to the prior art:

[0017] 1. Efficiency

[0018] The adjustable ringing device allows for faster girdling operations. This device, with adjustable opening diameter and width, increases girdling speed, significantly improving efficiency compared to conventional cutters and effectively reducing labor costs. Furthermore, the blade creates a smooth, horizontal band that is less likely to deviate, further improving work efficiency.

[0019] 2. Accuracy and Flexibility

[0020] The fruit tree girdling device with adjustable opening diameter and ring width can adjust the opening diameter and ring width of the jaws as needed, which enables it to fit tightly against the trunk when handling fruit trees of different diameters, achieving precise and uniform ringing, making it more flexible and applicable. This not only improves work efficiency, but also reduces damage to trees caused by unsuitable tools. Traditional girdling tools have limitations in applicability. They are usually only suitable for trees within a specific diameter range and for a specific ring width, lacking the necessary flexibility. This limitation leads to inconvenience and reduced efficiency during the operation. Frequent adjustments are not only time-consuming, but may also increase the risk of additional damage to trees. Compared with traditional girdling tools, the fruit tree girdling device with adjustable opening diameter and ring width is more stable during the girdling process and is less prone to deviation, thus ensuring the accuracy of the girdling.

[0021] 3. Security

[0022] The fruit tree ringing device, with adjustable opening diameter and ring width, is designed with operational safety in mind. The blades are securely fixed to prevent loosening, reducing potential safety hazards during operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form can also include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0035] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorized specification. In all examples shown and discussed herein, any specific values should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0036] See also Figures 1 to 7 As shown, the present invention provides a fruit tree ring-barking device with adjustable opening diameter and ring-barking width, which is mainly composed of four parts: a fixed ring-barking part 1, a movable ring-barking part 2, a clamp shaft 11 / axis hole 12 combination, and a clamp handle 3. The fixed ring-barking part 1 and the movable ring-barking part 2 both rotate around the clamp shaft 11 to form a structure similar to ordinary pliers. A plurality of axis holes 12 are provided on the fixed ring-barking part 1, and the axis holes 12 are divided into multiple gears. By adjusting the position of the clamp shaft 11 in the axis hole 12, the position of the movable ring-barking part 2 can be changed, thereby realizing the adjustment of the clamping diameter to adapt to fruit tree trunks or branches of different thicknesses.

[0037] This design allows the girdling tool to easily clamp onto a trunk or branch during use, achieving a stable girdling operation. The clamp shaft 11 on the movable girdling member 2 passes through and secures the fixed girdling member 1 with the axial hole 12, enabling a flexible connection between the fixed girdling member 1 and the movable girdling member 2. By adjusting the position of the clamp shaft 11 in the axial hole 12, the position of the movable girdling member 2 can be changed, thereby adjusting the clamping diameter to accommodate trunks or branches of varying thicknesses.

[0038] In addition, the fixed ring stripping member 1 and the movable ring stripping member 2 are each provided with two blades at their ends, forming two corresponding blade groups (i.e., double-layer ring stripping blades 5). Each blade group is in the same plane, and a certain gap is maintained between the two blade groups to ensure that the wood is not damaged during ring stripping. A skin scraping tip 4 is provided on the top of the fixed blade of the fixed ring stripping member 1 to clean the skin scraps left during the ring stripping process.

[0039] For the two blades (movable blade 53 and fixed blade 54) provided on both the fixed ring stripping part 1 and the movable ring stripping part 2, the fixed blade 54 is integrated with the fixed ring stripping part 1 or the movable ring stripping part 2, and the movable blade 53 is embedded in the scraping inner knife 52 and the gasket 51 at the same time. The scraping inner knife 52 is embedded in the rectangular hole 7 in the middle of the blade, and the gasket 51 firmly fixes the movable blade 53 on the fixed ring stripping part 1 or the movable ring stripping part 2 through the screw 8 and the nut 8a to ensure that the movable blade 53 will not loosen or fall off during use, and different gaskets 51 and scraping inner knives 52 can be replaced according to the width of the ring stripping.

[0040] The cutting edge of each blade is inclined from the outside to the inside, forming a curved edge. This design can more effectively ring-cut the phloem while reducing damage to the xylem.

[0041] The knife shaft adopts a multi-stage adjustable clamp shaft / shaft hole structure, which is convenient for adjusting and fixing the position of the ring stripping piece 1. By rotating the clamp shaft, the opening angle can be easily adjusted to adapt to tree trunks and branches of different diameters.

[0042] As a preferred embodiment, the distance between the double-layer ring-peeling blades 5 of the ring-peeling tool can be changed, so it is necessary to match the scraping inner knife 52 and the gasket 51 of different heights; for the scraping inner knife 52, the side embedded in the rectangular hole 7 is of fixed length, while the height of the side with the blade is 3mm, 5mm and 7mm respectively; for the gasket 51, its height is adapted to the scraping inner knife 52, and its height is 3mm, 5mm and 7mm respectively. That is to say, in actual use, the ring-peeling width can be changed by selecting different gaskets and scraping inner knives, and the ring-peeling widths are 3mm, 5mm and 7mm respectively.

[0043] like Figure 6 and Figure 7 As shown, the tail of the movable blade 53 is integrally provided with a step 531, which is either 2mm or 4mm high. In actual use, the movable blade 53 with the tail step 531 of varying heights is rotated according to the height of the spacer used. For example, when the ring-peeling width is 5mm, a 5mm spacer 51, a 5mm scraping inner blade 52, and a movable blade 53 with a 2mm height of step 531 should be used; when the ring-peeling width is 7mm, a 7mm spacer 51, a 7mm scraping inner blade 52, and a movable blade 53 with a 4mm height of step 531 should be used.

[0044] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0045] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
