Description

Technical Field

[0001] This utility model relates to the field of fruit tree girdling technology, and in particular to a fruit tree girdling device. Background Technology

[0002] Girdling is a fruit tree cultivation and management technique in which a tool is used to make a circular cut around the phloem (bark) of the trunk or main branches during the fruit tree's growing season. This cuts off the nutrient transport channels within the phloem, temporarily preventing the downward transport of organic nutrients produced by the leaves, and concentrating nutrients in the upper part of the branches. This promotes flower bud differentiation and increases fruit set. The girdling knife is a specialized tool used to perform girdling operations. It typically has a sharp circular blade or adjustable cutting depth, which can accurately cut the phloem without damaging the xylem. It meets the girdling needs of branches of different thicknesses and is a commonly used specialized tool in fruit tree girdling operations.

[0003] While girdling tools can be used to cut the bark of fruit trees, their cutting effect is affected when the bark is hard. Not only is it difficult to cut the bark smoothly, but it also requires the operator to exert a lot of effort, making the overall cutting operation quite laborious. Therefore, this application provides a fruit tree girdling device to meet the needs. Utility Model Content

[0004] This invention provides a fruit tree girdling device to solve the problem of laborious cutting when the bark of fruit trees is hard.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A fruit tree girdling device includes a housing, on the side of which are fixed a plurality of girdling blades arranged at intervals, all of which are inclined, and a gripping part integrally formed at the end of the housing; When in use, several ring cutters cut the fruit tree in sequence.

[0006] Preferably, the lengths of the plurality of said annular cutters increase sequentially from the direction near the gripping part to the direction away from the gripping part.

[0007] Preferably, the top and bottom of the circumferential cutter are provided with bevels, and the size of the bevels decreases sequentially from the direction closer to the gripping part to the direction farther away from the gripping part.

[0008] Preferably, a handle sleeve is fixedly fitted onto the surface of the grip portion, and the surface of the handle sleeve is provided with anti-slip protrusions. The handle sleeve is a rubber sleeve.

[0009] Preferably, the end of the handle sleeve is integrally formed with a raised ring.

[0010] Preferably, a cleaning component is provided on the side of the housing, which is used to clean debris between adjacent ring cutters.

[0011] Preferably, the cleaning assembly includes an inclined round rod that extends through the side of the housing, the inclination direction of the round rod being the same as that of the ring cutter. A square plate is fixedly connected to the end of the round rod, the square plate being movably connected to the inner wall of the housing. Several cleaning plates are fixed on the surface of the square plate, the cleaning plates and the ring cutters being staggered and distributed, and the cleaning plates extending through the housing. A limiting plate is fixed to the end of the round rod, and a spring is fixed between the limiting plate and the housing. The spring is sleeved on the surface of the round rod. During cleaning, pressing the round rod causes the cleaning plates to insert into the ring cutters.

[0012] Preferably, the side of the square plate is fixed with an inclined guide post, the inclination direction of the guide post is the same as the inclination direction of the round rod, and the inner wall of the shell is provided with a guide hole, in which the guide post is movably inserted.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, by setting up a shell and ring-cutting blades, when the bark of the fruit tree is relatively hard, the bark can be cut sequentially by several inclined ring-cutting blades. Each ring-cutting blade can peel off a small layer of bark. By cutting in sequence, the difficulty of cutting can be effectively reduced, making bark cutting more labor-saving.

[0014] The length of several cutting blades increases sequentially, allowing for step-by-step cutting of the bark. This saves effort while removing more bark each time, increasing the cutting speed.

[0015] By setting an inclined surface, the side of the ring cutter away from the housing is the cutting section. The inclined surface of this cutting section gradually narrows from the end near the grip to the end away from the grip, thereby increasing the length of the cutting section in sequence. The cutting end near the grip is pointed. When this pointed end contacts the fruit tree, it can increase the pressure between the ring cutter and the fruit tree, thus making it easier to insert into the bark. During the cutting process, the cutting is carried out step by step with the help of the cutting section with progressively increasing length. This not only makes the cutting operation smoother and less strenuous, but also increases the thickness of the bark cut each time while ensuring that the effort is saved.

[0016] By setting up a cleaning component, after a period of use, sawdust and other debris can easily get stuck between the blades of the circumcision cutter. At this time, pushing the limiting plate will cause the limiting plate to move the round rod towards the circumcision cutter. In turn, the round rod will cause the square plate and the cleaning plate to move closer to the circumcision cutter simultaneously. When the cleaning plate extends between the blades, it can push out and clean the stuck debris, preventing the debris from interfering with the normal operation of the circumcision cutter and ensuring its circumcision effect.

[0019] The following is a detailed description of a fruit tree girdling device provided by this utility model, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0020] like Figures 1-4 As shown, an embodiment of the present invention provides a fruit tree girdling device, including a housing 1, a plurality of girdling blades 3 arranged at intervals are fixed on the side of the housing 1, the plurality of girdling blades 3 are all inclined, and a gripping part 2 is integrally formed at the end of the housing 1. In use, several ring-cutting blades 3 cut the fruit tree in sequence. The housing 1 provides a mounting base for the ring-cutting blades 3, ensuring that the ring-cutting blades 3 are fixed in position. The inclined ring-cutting blades 3 can cut the bark of the fruit tree layer by layer in sequence. Each ring-cutting blade 3 peels off a small layer of bark, reducing the difficulty of cutting hard bark and making the operation more labor-saving. The grip part 2 makes it easy for the operator to hold and apply force, ensuring stability during the cutting process and improving the ring-cutting efficiency.

[0021] like Figures 1-3 As shown in this embodiment, the length of several ring-cutting blades 3 increases sequentially from the direction near the gripping part 2 to the direction away from the gripping part 2. The gradual increase in the length of the ring-cutting blades 3 can achieve progressively deeper cutting of the bark. While saving effort, each cut can peel off more bark, reduce the number of cuts, increase the ring-cutting speed, avoid excessive force in a single cut that could cause the bark to tear, ensure that the wound after girdling of the fruit tree is smooth, and facilitate the recovery of the fruit tree.

[0022] like Figure 1 and Figure 2As shown in this embodiment, the top and bottom of the ring-cutting blade 3 are both provided with inclined surfaces 4. The size of the inclined surfaces 4 decreases gradually from the direction near the gripping part 2 to the direction away from the gripping part 2. The inclined surfaces 4 make the ring-cutting blade 3 form a sharp cutting end. The inclined surfaces 4 of the ring-cutting blade 3 near the gripping part 2 are larger, and the cutting end is pointed, which can increase the pressure with the bark and easily insert into the bark. The inclined surfaces 4 decrease as the length of the ring-cutting blade 3 increases, so that the length of the cutting part increases step by step, realizing step-by-step cutting. This ensures smooth and labor-saving operation, increases the thickness of the bark cut each time, and improves the ring-cutting efficiency.

[0023] like Figure 1 and Figure 2 As shown in this embodiment, a handle 5 is fixedly sleeved on the surface of the grip 2. The surface of the handle 5 is provided with anti-slip protrusions. The handle 5 is a rubber sleeve. The rubber handle 5 is soft and elastic, which can buffer the impact force when gripping and improve the operating comfort. The anti-slip protrusions increase the friction between the hand and the handle 5, prevent the hand from slipping during operation, ensure stable force application, prevent hand fatigue caused by long-term gripping, and ensure the convenience of long-term operation.

[0024] like Figure 1 and Figure 2 As shown in this embodiment, the end of the grip 5 is integrally formed with a protruding ring 13. The protruding ring 13 can restrict the sliding of the hand on the grip part 2, further improve the stability of the grip, and prevent the hand from slipping off the end of the grip 5 when the operator applies force.

[0025] like Figures 1-4 As shown in this embodiment, a cleaning component 6 is provided on the side of the housing 1. The cleaning component 6 is used to clean the debris between adjacent ring cutters 3. The cleaning component 6 can promptly remove sawdust and other debris stuck between adjacent ring cutters 3, avoid the debris from affecting the cutting effect of the ring cutter 3, prevent the accumulation of debris from causing the ring cutter 3 to jam, and ensure the smoothness of the ring cutting process.

[0026] like Figure 4As shown, in this embodiment, the cleaning assembly 6 includes an inclined round rod 10 that movably penetrates the side of the housing 1. The inclination direction of the round rod 10 is the same as that of the ring cutter 3. A square plate 7 is fixedly connected to the end of the round rod 10. The square plate 7 is movably connected to the inner wall of the housing 1. Several cleaning plates 8 are fixed on the surface of the square plate 7. The cleaning plates 8 are staggered with the ring cutters 3 and movably penetrate the housing 1. A limiting plate 11 is fixed to the end of the round rod 10. A spring 12 is fixed between the limiting plate 11 and the housing 1. Spring 12 is sleeved on the surface of round rod 10. During cleaning, pressing round rod 10 causes several cleaning plates 8 to be inserted into several ring cutters 3. Round rod 10 is tilted to match the ring cutter 3. Pressing round rod 10 can drive square plate 7 and cleaning plate 8 to move synchronously. Cleaning plate 8 is inserted between adjacent ring cutters 3 to quickly push out debris. After cleaning, spring 12 can drive round rod 10, square plate 7 and cleaning plate 8 to automatically reset without manual adjustment. The staggered distribution of cleaning plates 8 ensures that debris between each ring cutter 3 can be cleaned, ensuring cleaning effect.

[0027] like Figure 4 As shown in this embodiment, an inclined guide post 9 is fixed on the side of the square plate 7. The inclined direction of the guide post 9 is the same as that of the round rod 10. A guide hole is opened on the inner wall of the housing 1. The guide post 9 is movably inserted into the guide hole. The guide post 9 cooperates with the guide hole to provide guidance for the movement of the square plate 7, ensuring that the square plate 7 and the cleaning plate 8 move in a fixed direction, and avoiding deviation that would prevent the cleaning plate 8 from being accurately inserted between the ring cutters 3.

[0028] Working principle: Hold the gripping part 2 at the end of the housing 1, align the several inclined ring-cutting blades 3 on the side of the housing 1 with the bark of the fruit tree, so that the shortest ring-cutting blade 3 closest to the gripping part 2 contacts the bark first; When the housing 1 is pushed, the ring cutter 3, which is close to the grip 2, has bevels 4 at its top and bottom. The bevels 4 are relatively large, and the ring cutter 3, which has a pointed cutting end, first inserts into the bark. As the pushing force increases, the ring cutter 3 peels off a small layer of bark. As the housing 1 is pushed, the ring cutter 3, which has a length that increases and a bevel 4 that decreases in a stepwise manner, cuts the bark in a stepwise manner from the direction close to the grip 2 to the direction away from the grip 2, peeling off more bark step by step. During the girdling process, if sawdust or other debris gets stuck between adjacent girdling blades 3, press the round rod 10 of the cleaning component 6. The round rod 10 drives the limiting plate 11 to compress the spring 12, and at the same time drives the square plate 7 to move. Several cleaning plates 8 on the surface of the square plate 7 are inserted between adjacent girdling blades 3 to push out the debris. Release the round rod 10, and the spring 12 will rebound, causing the limit plate 11, the round rod 10, the square plate 7 and the cleaning plate 8 to reset, and the cleaning plate 8 will disengage from the ring cutter 3.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
