Description

Technical Field

[0001] The invention relates to the technical field of garden cultivation, in particular to a camellia cutting device. Background Art

[0002] When cultivating camellia, it is often necessary to perform girdling operations on the camellia. During the girdling process, the difficulty and difficulty of girdling are different for different branches. For relatively thick branches, their hardness is relatively high, and the force required for girdling is relatively large. For relatively thin branches, they are relatively tender, and although the force required for girdling is small, it is easy to have the problem of excessive cutting depth, and in severe cases, it may directly lead to branch breakage.

[0003] At present, ring cutting is usually done manually, which requires high technical proficiency of skilled workers. Problems such as improper ring cutting leading to damage or even breakage of branches and trunks often occur.

[0004] In view of this, this application is hereby filed. Summary of the invention

[0005] The object of the present invention is to provide a camellia cutting device, which can effectively improve the cutting accuracy of the ring cutting operation and reduce the requirements of the ring cutting operation on the technical proficiency of workers. It is suitable for the ring cutting operation of branches of different thicknesses and significantly reduces the probability of damage or breakage of branches due to improper ring cutting.

[0006] The embodiment of the present invention is achieved as follows: A camellia cutting device comprises: a supporting end, a first half ring body, a second half ring body, a positioning column, an air supply mechanism, an air pressure sensor, a moving seat, a ring cutting blade and a controller.

[0007] One end of the first half ring body and the second half ring body are both hinged to the supporting end, so that the first half ring body and the second half ring body can be separated and closed to form a complete ring body by rotating relative to each other.

[0008] The inner ring walls of the first semi-ring body and the second semi-ring body are both provided with a receiving groove, and the receiving groove is matched with a positioning column. Along the radial direction of each of the first semi-ring body and the second semi-ring body, the positioning column is slidably matched with the receiving groove and slidably sealed. A first elastic member is connected between the groove bottom of the receiving groove and the positioning column, and the first elastic member is in an elastically stretched state.

[0009] The air supply mechanism is communicated with the containing tank, and the air pressure sensor is arranged in the containing tank.

[0010] The side wall of the first semi-ring body has a first arc-shaped track, and the side wall of the second semi-ring body has a second arc-shaped track. When the first semi-ring body and the second semi-ring body are closed, the first arc-shaped track and the second arc-shaped track are closed to form a complete annular track.

[0011] The moving seat is used to cooperate with the first arc rail and the second arc rail, so that when the first arc rail and the second arc rail are closed, the moving seat can move along the complete annular rail. The moving seat is driven by a power mechanism, and the annular cutting blade is installed on the moving seat and the cutting depth is adjusted by a telescopic mechanism.

[0012] The air supply mechanism, the air pressure sensor, the power mechanism and the telescopic mechanism are all electrically connected to the controller.

[0013] The complete ring body is used to be arranged around the target branch. The controller is used to control the gas supply mechanism to supply a preset volume of gas into the receiving groove, and the air pressure sensor is used to detect the air pressure in the receiving groove. The controller is used to determine the extension distance of the positioning column according to the preset volume and air pressure, and determine the diameter of the target branch according to the extension distance of each positioning column. The controller is also used to determine the cutting depth of the ring cutting blade according to the diameter of the target branch.

[0014] Furthermore, a cavity is provided on the end surface of the positioning column close to the bottom of the accommodating groove, and the cavity extends along the axial direction of the positioning column toward the end of the positioning column away from the accommodating groove. The first elastic member is connected between the bottom of the accommodating groove and the end wall of the cavity away from the accommodating groove.

[0015] Furthermore, the first semi-ring body is provided with an exhaust pipe, the inlet end of the exhaust pipe is communicated with the containing groove, and the outlet end of the exhaust pipe is arranged toward the first arc-shaped rail. The exhaust pipe has a control valve, and the control valve is electrically connected to the controller.

[0016] The moving seat is provided with an air guide channel, which runs through the moving seat, and the outlet end of the air guide channel is arranged toward the circumcision blade. The moving seat has a reference state, when the moving seat is in the reference state, the moving seat is located on the first arc track, and the inlet end of the air guide channel is connected with the outlet end of the exhaust pipe.

[0017] Furthermore, when the controller controls the gas delivery mechanism to deliver a preset volume of gas into the containing tank, the gas is delivered at a preset gas supply speed.

[0018] The controller is also used to determine the smoothness of the movement of the positioning column according to the air pressure data detected by the air pressure sensor, including the following steps: S1. For positioning columns that meet the smoothness requirements, collect the air pressure-time data during the process of delivering a preset volume of gas at a preset air supply speed as standard data.

[0019] S2. During the ring cutting process, the air pressure-time data in the process of delivering a preset volume of gas at a preset air supply speed is collected as evaluation data.

[0020] S3. Compare the standard data with the evaluation data. At the same time point, if the air pressure value in the evaluation data is greater than the air pressure value in the standard data, it is determined that the movement smoothness of the positioning column is insufficient.

[0021] Furthermore, a blind installation hole is provided on the end face of the positioning column away from the receiving groove, a matching column is slidably matched in the blind installation hole, a second elastic member is abutted between the matching column and the bottom wall of the blind installation hole, and a side wall of the matching column has a rack extending along its axial direction.

[0022] A groove is also provided on the end face of the positioning column away from the receiving groove, and the grooves are arranged on opposite sides of the installation blind hole. A notch connected to the installation blind hole is provided on the groove wall near the installation blind hole, and a matching gear is installed in the notch, and the matching gear meshes with the rack.

[0023] An abutment plate is arranged in the groove, and the abutment plate is rotated by the connecting arm to match the matching gear. A torsion spring is matched between the connecting arm and the matching gear to drive the connecting arm to rotate out of the groove relative to the matching gear. A stop block is fixedly connected to the side of the matching gear to prevent the connecting arm from rotating out of the groove relative to the matching gear.

[0024] When the end face of the positioning column away from the receiving groove abuts against the target branch, the matching column is completely pushed into the installation blind hole by the target branch, and the matching column drives the matching gear and makes the abutment plate fit the surface of the target branch.

[0025] Furthermore, the surface of the abutment plate is subjected to anti-slip treatment.

[0026] The beneficial effects of the technical solution of the embodiment of the present invention include: The camellia cutting device provided in the embodiment of the present invention can automatically determine the cutting depth according to the actual situation of the target branch, while ensuring sufficient ring cutting and avoiding excessive damage to the main part of the branch.

[0027] In general, the camellia cutting device provided by the embodiment of the present invention can effectively improve the cutting accuracy of the ring cutting operation and reduce the requirements of the ring cutting operation on the technical proficiency of workers. It is suitable for ring cutting operations on branches of different thicknesses and significantly reduces the probability of damage or breakage of branches due to improper ring cutting.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0034] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0035] In addition, the terms "parallel", "vertical", etc. do not mean that the components must be absolutely parallel or vertical, but can be slightly tilted. For example, "parallel" only means that its direction is more parallel than "vertical", and does not mean that the structure must be completely parallel, but can be slightly tilted.

[0036] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting", "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In order to overcome the shortcomings of the prior art, please refer to Figure 1-Figure 5 The present embodiment provides a camellia cutting device, which includes: a supporting end 100, a first semi-ring body 200, a second semi-ring body 300, a positioning column 500, an air supply mechanism (not shown in the figure), an air pressure sensor (not shown in the figure), a moving seat 600, a ring cutting blade 700 and a controller (not shown in the figure).

[0038] The supporting end 100 may be handheld or may be a mechanical arm, but is not limited thereto.

[0039] The first semi-ring body 200 and the second semi-ring body 300 are both semi-circular, and one end of the first semi-ring body 200 and the second semi-ring body 300 are both hinged to the support end 100. The first semi-ring body 200 and the second semi-ring body 300 can rotate relative to the support end 100, so that the first semi-ring body 200 and the second semi-ring body 300 can be separated and closed to form a complete ring body by rotating relative to each other. The opening and closing of the first semi-ring body 200 and the second semi-ring body 300 are controlled by a rotation driver (not shown in the figure).

[0040] The inner ring walls of the first semi-ring body 200 and the second semi-ring body 300 are both provided with a receiving groove 410, and the receiving groove 410 is matched with a positioning column 500. Along the radial directions of the first semi-ring body 200 and the second semi-ring body 300, the positioning column 500 is slidably matched with the receiving groove 410 and slidably sealed. That is to say, for the positioning column 500 arranged on the first semi-ring body 200, the positioning column 500 is arranged along the radial direction of the first semi-ring body 200 and slidably matched with the receiving groove 410 of the first semi-ring body 200; for the positioning column 500 arranged on the second semi-ring body 300, the positioning column 500 is arranged along the radial direction of the second semi-ring body 300 and slidably matched with the receiving groove 410 of the second semi-ring body 300.

[0041] A first elastic member 420 is connected between the bottom of the receiving groove 410 and the positioning column 500, and the first elastic member 420 is in an elastically stretched state. Optionally, the first elastic member 420 is a tension spring, but is not limited thereto.

[0042] In a natural state, the positioning post 500 is received in the receiving groove 410. The air supply end of the air supply mechanism is in communication with the receiving groove 410, so as to supply gas into the receiving groove 410, thereby pushing the positioning post 500 out of the receiving groove 410. The air pressure sensor is disposed in the receiving groove 410, and can be specifically disposed at the bottom of the receiving groove 410, so as to detect the air pressure in the receiving groove 410.

[0043] The side wall of the first semi-ring body 200 has a first arc-shaped rail 430, and the side wall of the second semi-ring body 300 has a second arc-shaped rail 440. The central angles of the first arc-shaped rail 430 and the second arc-shaped rail 440 are both 180°.

[0044] When the first half ring body 200 is separated from the second half ring body 300, the first arc track 430 is separated from the second arc track 440. When the first half ring body 200 and the second half ring body 300 are closed, the first arc track 430 and the second arc track 440 are also closed and form a complete annular track. In this embodiment, when the first arc track 430 and the second arc track 440 are closed, the complete annular track formed is a circular track.

[0045] The moving seat 600 is used to cooperate with the first arc rail 430 and the second arc rail 440, so that when the first arc rail 430 and the second arc rail 440 are closed, the moving seat 600 can move along the complete annular rail. The moving seat 600 is driven by a power mechanism (not shown in the figure), and the ring cutting blade 700 is installed on the moving seat 600 and the cutting depth is adjusted by a telescopic mechanism (not shown in the figure). Specifically, the telescopic mechanism is used to adjust the position of the ring cutting blade 700 in the radial direction of the complete annular rail, and adjust the position of the ring cutting blade 700 from the central axis of the complete annular rail.

[0046] When the first half ring body 200 and the second half ring body 300 are closed, the complete ring body and the complete annular track are coaxially arranged.

[0047] The air supply mechanism, air pressure sensor, power mechanism and telescopic mechanism are all electrically connected to the controller and are uniformly controlled by the controller.

[0048] The complete ring body is used to be arranged around the target branch 2000, that is, the opening and closing of the first half ring body 200 and the second half ring body 300 can be controlled by controlling the rotation driver, so as to enclose the target branch 2000 between the first half ring body 200 and the second half ring body 300.

[0049] The controller is used to control the gas delivery mechanism to deliver a preset volume of gas to each receiving groove 410, and the air pressure sensor is used to detect the air pressure in the receiving groove 410. When the preset volume of gas is delivered to each receiving groove 410, due to the increase in the air pressure in the receiving groove 410, the positioning column 500 is pushed out of the receiving groove 410, so that the positioning column 500 and the target branch 2000 are against each other. In this way, the positioning column 500 can be used to lock the target branch 2000, so that the complete ring body and the target branch 2000 remain relatively still as much as possible, so as to facilitate the subsequent ring cutting operation.

[0050] At the same time, when the positioning column 500 abuts against the object branch 2000, the positioning column 500 cannot move further outside the receiving groove 410, and the space in the receiving groove 410 that can be used to accommodate gas is fixed. Then, conversely, the actual size of the space in the receiving groove 410 that can be used to accommodate gas can be inverted based on the final gas pressure in the receiving groove 410, that is, the actual extension distance of the positioning column 500 can be determined by inversion.

[0051] Based on this, the controller is also used to determine the extension distance of the positioning post 500 according to the volume of gas input into the containing groove 410 (i.e., the preset volume) and the final gas pressure after the positioning post 500 and the target branch 2000 collide. When the extension distance of each positioning post 500 is determined, the diameter of the target branch 2000 can be determined according to the extension distance of each positioning post 500.

[0052] Since the diameter of the target branch 2000 can be determined, once the diameter of the target branch 2000 is determined, the thickness of the cortex of the target branches 2000 of different thicknesses can be determined based on statistical data. Based on the cortex thickness corresponding to the branches of different thicknesses, the controller can also determine the cutting depth of the ring cutting blade 700 according to the diameter of the target branch 2000, so that during ring cutting, the cortex can be fully removed at one time without causing excessive damage to the main body of the branch.

[0053] Through the above design, the camellia cutting device can automatically determine the cutting depth according to the actual situation of the target branch 2000, while ensuring sufficient ring cutting and avoiding excessive damage to the main part of the branch.

[0054] Among them, the actual cutting depth corresponding to branches of different thicknesses can also be flexibly adjusted according to actual needs, and this application does not make specific restrictions.

[0055] In general, the camellia cutting device provided in this embodiment can effectively improve the cutting accuracy of the ring cutting operation and reduce the requirements for the technical proficiency of workers in the ring cutting operation. It is suitable for ring cutting operations on branches of different thicknesses and significantly reduces the probability of damage or breakage of branches due to improper ring cutting.

[0056] In this embodiment, a cavity 510 is opened on the end surface of the positioning column 500 close to the bottom of the receiving groove 410, and the cavity 510 extends along the axial direction of the positioning column 500 toward the end of the positioning column 500 away from the receiving groove 410, and the first elastic member 420 is connected between the bottom of the receiving groove 410 and the end wall of the cavity 510 away from the receiving groove 410.

[0057] This design can effectively reduce the weight of the positioning column 500. In addition, even if the positioning column 500 is relatively long, in order to ensure that there is enough space in the receiving groove 410 for accommodating gas, the depth of the receiving groove 410 does not need to be too deep. This is conducive to reducing the radial dimensions of the first semi-ring body 200 and the second semi-ring body 300, and can also effectively ensure the matching stability of the positioning column 500 in the receiving groove 410.

[0058] Furthermore, the first semi-ring body 200 is provided with an exhaust pipe 450, the inlet end of the exhaust pipe 450 is communicated with the receiving groove 410, and optionally, all the receiving grooves 410 are communicated with the inlet end of the exhaust pipe 450, and exhaust is uniformly performed by the exhaust pipe 450. The main part of the exhaust pipe 450 is located on the side of the first arc-shaped rail 430 away from the inner ring wall of the first semi-ring body 200, and the outlet end of the exhaust pipe 450 is arranged toward the first arc-shaped rail 430.

[0059] The exhaust pipe 450 has a control valve (not shown in the figure) for controlling the opening and closing of the exhaust pipe 450. The control valve is electrically connected to the controller and is controlled by the controller. The control valve is in a normally closed state.

[0060] The ring cutting blade 700 may be a U-shaped blade.

[0061] The moving seat 600 is provided with an air guide channel 610, which runs through the moving seat 600. The outlet end of the air guide channel 610 is arranged toward the ring cutting blade 700, and the inlet end of the air guide channel 610 is located at a side of the moving seat 600 away from the ring cutting blade 700.

[0062] The moving seat 600 has a reference state. When the moving seat 600 is in the reference state, the moving seat 600 is located on the first arc-shaped rail 430 , and the inlet end of the air guide channel 610 is connected to the outlet end of the exhaust pipe 450 .

[0063] When performing circumcision, the position of the moving seat 600 when it is in the reference state can be used as the initial position. When the moving seat 600 moves along the complete circular track for one circle and returns to the position corresponding to the reference state, it means that the circumcision blade 700 has cut a circle on the target branch 2000 and has completed the circumcision of the target branch 2000. At this time, the controller can open the control valve, and the gas in all the containing grooves 410 can enter the air guide channel 610 through the exhaust pipe 450, and be blown toward the circumcision blade 700 under the guidance of the air guide channel 610. The airflow is used to clean the circumcision blade 700 to prevent the branch bark or other impurities from adhering to the circumcision blade 700, thereby facilitating continuous circumcision operations.

[0064] It should be noted that since the positioning column 500 is originally used to abut against the target branch 2000 to fix the target branch 2000, the space used to accommodate gas in the receiving groove 410 is limited, and the air pressure in the receiving groove 410 will be relatively high. After the control valve is opened, a high-intensity airflow can be formed, effectively ensuring the cleaning effect of the ring cutting blade 700.

[0065] At the same time, while the airflow is used to clean the circumcision blade 700, pressure relief is achieved in the receiving groove 410. Under the action of the first elastic member 420, the positioning column 500 can fully return to the receiving groove 410 to achieve resetting, so as to facilitate the next circumcision work. In addition, it is also beneficial to fully discharge the excess gas in the receiving groove 410. On the one hand, it can enhance the cleaning effect of the circumcision blade 700, and on the other hand, it can avoid interference with the determination of the diameter of the target branch 2000 in the next circumcision operation.

[0066] When the gas in each containing tank 410 is fully discharged, the controller can control the control valve to close again.

[0067] It should be noted that when the controller controls the gas supply mechanism to deliver a preset volume of gas into the containing tank 410, the gas is delivered at a preset gas supply speed.

[0068] The controller is also used to determine the movement smoothness of the positioning column 500 according to the air pressure data detected by the air pressure sensor, including the following steps: S1. For a positioning column 500 that meets the smoothness requirement (i.e., a positioning column 500 with qualified smoothness is selected), for the positioning column 500, the air pressure-time data during the process of delivering a preset volume of gas at a preset air supply speed is collected as standard data.

[0069] S2. During the ring cutting process, for each positioning column 500 of the camellia cutting device being used, the air pressure-time data in the process of supplying a preset volume of gas into the containing tank 410 at a preset air supply speed is collected as evaluation data.

[0070] S3. Compare the standard data with the evaluation data. At the same time point, if the air pressure value in the evaluation data is greater than the air pressure value in the standard data, it means that the extension length of the current positioning column 500 at the same time point is less than that of the positioning column 500 with qualified smoothness, and it is determined that the movement smoothness of the positioning column 500 is insufficient.

[0071] In this way, the smoothness and smoothness of each positioning column 500 can be synchronously and conveniently detected during the ring cutting process, which can effectively ensure the normal operation of the camellia cutting device.

[0072] During the girdling process, for a thicker target branch 2000, the cortex hardness and thickness are usually greater, and the force required for cutting is relatively greater. For a thinner target branch 2000, the cortex hardness and thickness are usually smaller, and the force required for cutting is relatively smaller.

[0073] In order to better adapt to the cutting work of branches 2000 of different thicknesses, please further combine Figure 6 and Figure 7 The end surface of the positioning column 500 away from the receiving groove 410 is provided with a mounting blind hole 520, and a matching column 530 is slidably matched in the mounting blind hole 520, and a second elastic member 540 is abutted between the matching column 530 and the bottom wall of the mounting blind hole 520. The side wall of the matching column 530 has a rack (not shown in the figure) extending along its axial direction. The mounting blind hole 520 is coaxially arranged with the positioning column 500, the depth of the mounting blind hole 520 is greater than the length of the matching column 530, the outer wall of the matching column 530 is in contact with the hole wall of the mounting blind hole 520, and the mouth of the mounting blind hole 520 is provided with an anti-slip structure (not shown in the figure) for preventing the matching column 530 from completely slipping out of the mounting blind hole 520.

[0074] A groove 550 is further formed on the end surface of the positioning column 500 away from the receiving groove 410, and the grooves 550 are arranged on opposite sides of the installation blind hole 520. A notch connected to the installation blind hole 520 is formed on the groove wall of the groove 550 near the installation blind hole 520, and a matching gear 560 is installed in the notch, and the matching gear 560 is meshed with the rack. A part of the matching gear 560 is located in the groove 550.

[0075] The groove 550 contains an abutment plate 570, which is rotatably engaged with the mating gear 560 by a connecting arm 580. The connecting arm 580 is fixedly connected to the abutment plate 570, and one end of the connecting arm 580 away from the abutment plate 570 is rotatably engaged with the mating gear 560. In this embodiment, the rotation axis of the connecting arm 580 relative to the mating gear 560 is arranged to coincide with the rotation axis of the mating gear 560 relative to the positioning column 500.

[0076] A torsion spring (not shown) is provided between the connecting arm 580 and the mating gear 560 to drive the connecting arm 580 to rotate out of the groove 550 relative to the mating gear 560. Figure 6 As shown in the K direction.

[0077] A stopper 590 is fixedly connected to the side of the mating gear 560. In a natural state, the connecting arm 580 abuts against the stopper 590 to prevent the connecting arm 580 from rotating relative to the mating gear 560 out of the groove 550. Due to the existence of the stopper 590, under the torsion of the torsion spring, when the connecting arm 580 abuts against the stopper 590, the connecting arm 580 and the mating gear 560 are relatively stationary.

[0078] It should be noted that the elastic force of the second elastic member 540 and the torsion force of the torsion spring are both smaller than the abutment force between the positioning column 500 and the target branch 2000 .

[0079] When the end face of the positioning column 500 away from the accommodating groove 410 abuts against the target branch 2000, the matching column 530 is completely pushed into the installation blind hole 520 by the target branch 2000, and the second elastic member 540 is elastically compressed. The matching column 530 drives the matching gear 560 to rotate by using the rack on its side. When the matching gear 560 rotates, it drives the abutment plate 570 to rotate through the connecting arm 580, so that the abutment plate 570 moves toward the surface of the target branch 2000 and makes the abutment plate 570 fit the surface of the target branch 2000.

[0080] For target branches 2000 of different thicknesses, after the positioning column 500 abuts against the target branch 2000, the matching column 530 is completely pushed into the mounting blind hole 520, that is, the rotation angle of the matching gear 560 is the same during this process. If the target branch 2000 is thicker, after the abutment plate 570 fits against the target branch 2000, even if the matching gear 560 continues to rotate, the abutment plate 570 can drive the connecting arm 580 to deflect against the torsion of the torsion spring, that is, the connecting arm 580 can be separated from the stop block 590 to adapt to target branches 2000 of different thicknesses.

[0081] With this design, for thinner target branches 2000, the extended length of the positioning column 500 is larger, and after the abutment plate 570 is in contact with the target branch 2000, the angle at which the abutment plate 570 rotates to overcome the torsion of the torsion spring is smaller, and the force applied to the target branch 2000 by the positioning column 500 and the abutment plate 570 is relatively small. This can fully meet the requirements for girdling positioning of thinner target branches 2000, while also avoiding damage to the branches due to excessive positioning force.

[0082] For a thicker target branch 2000, the protruding length of the positioning column 500 is smaller, and after the abutment plate 570 is in contact with the target branch 2000, the abutment plate 570 can rotate at a larger angle to overcome the torsion of the torsion spring. The force applied to the target branch 2000 by the positioning column 500 and the abutment plate 570 is relatively large, which can fully meet the requirements for the ring cutting positioning of the thicker target branch 2000, and also avoids slipping during ring cutting due to excessive positioning force, thereby ensuring the smooth progress of the ring cutting operation.

[0083] Optionally, the surface of the abutment plate 570 is treated with anti-slip treatment so as to better fix the target branch 2000.

[0084] To sum up, the camellia cutting device provided in the embodiment of the present invention can effectively improve the cutting accuracy of the ring cutting operation and reduce the requirements of the ring cutting operation on the technical proficiency of workers. It is suitable for the ring cutting operation of branches of different thicknesses and significantly reduces the probability of damage or breakage of branches due to improper ring cutting.
