Description

Technical Field

[0001] The present invention relates to the technical field of agricultural and forestry machinery and tools, and in particular to a fruit tree ring cutting machine and a ring cutting method. Background Art

[0002] Girdling (also known as girdling) is a technique for making circular cuts on branches during the growing season of fruit trees. By stripping the bark between the two cuts and exposing the xylem, girdling temporarily hinders the downward transport of organic matter, reducing nutrient supply to the root system while promoting nutrient accumulation above the cut. This effectively inhibits vegetative growth, promotes flower bud differentiation, and significantly improves fruit quality. Existing electric girdling equipment suffers from the following practical problems: Due to the inconsistent hardness and surface flatness of the bark (for example, knots are more uneven and harder), the actual cutting force during girdling is often unstable, and the equipment is prone to vibration and deviation. This can lead to excessive cutting depth, motor stalling, or insufficient cutting depth, resulting in incomplete bark removal. These issues not only significantly reduce the efficiency of girdling operations but can also cause unnecessary damage to fruit trees, limiting the promotion and application of electric girdling technology. Therefore, there is a need to design electric girdling equipment that operates smoothly and is easy to operate to improve the overall effectiveness of girdling operations. Summary of the Invention

[0037] The embodiment of the present invention provides a fruit tree ring cutting machine, combined with Figure 1-9 As shown, it includes a casing 1, a rotating disk 4, a fastening assembly 2, a cutting assembly 3, and a driving member 5. The casing 1 is provided with a cutting cavity 11 suitable for placing a tree trunk, and the rotating disk 4 is provided with a tree clamping mouth 41 connected to the cutting cavity 11. The driving member 5 drives the rotating disk 4 to rotate, and the rotating disk 4 and the casing 1 are rotationally connected. The fastening assembly 2 and the cutting assembly 3 are both connected to the rotating disk 4 and rotate around the cutting cavity 11 together with the rotating disk 4; the fastening assembly 2 includes a first connecting rod 22, the side wall of the first connecting rod 22 is suitable for abutting the tree trunk in the cutting cavity 11, and the rotating disk 4 is provided with a fixing seat 42. The fixing seat 42 is provided with a first mounting column 421 and a mounting hole 422, the first mounting column 421 is rotatably connected to the first connecting rod 22, and the first mounting column 421 is sleeved with a first torsion spring 43, one end of the torsion arm of the first torsion spring 43 is inserted into the mounting hole 422, and the other end of the torsion arm of the first torsion spring 43 is abutted against the side of the first connecting rod 22 away from the cutting cavity 11 to provide an inward elastic force to press the trunk; the cutting assembly 3 includes a cutting knife 31, the cutting knife 31 and the first connecting rod 22 cooperate to clamp the trunk in the cutting cavity 11, and the cutting knife 31 rotates with the rotating disk 4 and performs ring cutting on the trunk.

[0038] Optionally, the fastening assembly 2 includes a tension spring 21 and a first abutment 23, the first connecting rod 22 and the first abutment 23 are rotatably connected, the first abutment 23 is suitable for abutting the tree trunk in the cutting cavity 11, and both ends of the tension spring 21 are simultaneously connected to the first connecting rod 22 and the first abutment 23 to provide an inward pulling force to press the tree trunk.

[0039] like Figure 1 and 4 As shown, in this embodiment, the tree clamping opening 41 is approximately U-shaped. When in use, the user can place the tree into the cutting cavity 11 through the U-shaped tree clamping opening 41, cooperate with the circular cutting track of the cutting component 3, and slide clockwise to ensure that the cutting process is smooth and fluent, thereby improving the convenience of operation and work efficiency.

[0040] like Figure 6As shown, a slide groove 45 is provided at the bottom of the rotating disk 4, and a slide rail 15 is provided in the housing 1. The slide groove 45 and the slide rail 15 are slidably connected to each other so that the rotating disk 4 rotates around the cutting cavity 11 to perform tree trunk girdling. The side of the first connecting rod 22 close to the cutting cavity 11 is arc-shaped and suitable for abutting the tree trunk in the cutting cavity 11. The side of the first abutting member 23 close to the cutting cavity 11 is also arc-shaped. One end of the first connecting rod 22 is rotatably connected to the middle part of the first abutting member 23. The end of the first abutting member 23 away from the first connecting rod 22 is provided with an abutting portion 232 suitable for abutting the tree trunk. The abutting portion 232 is approximately in the shape of a water droplet to increase the pressure at the end of the water droplet, making the abutting effect more stable.

[0041] One end of the first abutment member 23 is provided with a connecting portion 231, which is provided at the end of the first abutment member 23 away from the abutment portion 232. The end of the first connecting rod 22 away from the connecting portion 231 is provided with a connecting hole 223, and both ends of the tension spring 21 are hooked to the connecting portion 231 and the connecting hole 223 at the same time.

[0042] The tree enters the cutting chamber 11 and waits for ring cutting. When starting work, the fastening assembly 2 rotates into the cutting chamber 11 and presses against the trunk, so that the trunk is restricted within a certain range of movement, thereby improving the stability during cutting; the first connecting rod 22 and the first abutment 23 are rotationally connected, and an inward pulling force is always provided through the tension spring 21 to counteract the repulsive force caused by the uneven surface of the cut tree, which can better fit the surface shape of the tree, always maintain a stable fastening effect on the tree, and effectively improve the cutting effect under complex cutting conditions.

[0043] Optionally, a positioning seat 12 is convexly provided on the housing 1, and a positioning block 13 is rotatably connected to the positioning seat 12. A second torsion spring 14 is connected between the positioning seat 12 and the positioning block 13. The torsion arms at both ends of the second torsion spring 14 respectively abut the positioning seat 12 and the positioning block 13. A positioning portion 221 is convexly provided at one end of the first connecting rod 22, and the positioning portion 221 is adapted to abut against the positioning block 13. The positioning block 13 is limited to the reverse rotation path of the positioning portion 221; the fastening assembly 2 also includes a first limiting column 24, and the first connecting rod 2 2 is provided with a limit block 222, the first limit column 24 is provided on the rotation path of the limit block 222 and is suitable for abutting against the limit block 222, and the first limit column 24 is suitable for abutting against the positioning portion 221; when the positioning portion 221 is limited between the positioning block 13 and the first limit column 24, the fastening assembly 2 is in the initial position, and when the first connecting rod 22 rotates forward around the cutting cavity 11, the positioning portion 221 is separated from the positioning block 13, so that the first connecting rod 22 can rotate into the cutting cavity 11 and press against the tree trunk.

[0044] like Figure 2As shown, in this embodiment, the end of the positioning block 13 away from the positioning seat 12 is adapted to abut against the positioning portion 221, and the positioning portion 221 protrudes in a direction away from the cutting chamber 11. When an external force drives the positioning block 13 to rotate counterclockwise relative to the positioning seat 12, the second torsion spring 14 is compressed. When the external force disappears, the positioning block 13 returns to its original position under the action of the second torsion spring 14.

[0045] The stop block 222 is located on the side closest to the cutting chamber 11. When the fastening assembly 2 is in its initial position, the rotating disk 4 is locked, and the positioning portion 221 is confined between the first stop post 24 and the positioning block 13. At this time, the first torsion spring 43 is in a compressed state. When the rotating disk 4 begins to rotate clockwise, the positioning portion 221 rotates with the rotating disk 4 around the cutting chamber 11 and away from the positioning block 13. At this time, the first torsion spring 43 drives the first connecting rod 22 to rotate away from the positioning block 13 until the stop block 222 abuts the first stop post 24.

[0046] A curved guide portion 131 is provided on the side of the positioning block 13 near the cutting chamber 11. The guide portion 131 is adapted to be slidably connected to the positioning portion 221. When the rotating disk 4 rotates one revolution, the positioning portion 221 slides past the guide portion 131 and, through the guide portion 131, causes the positioning block 13 to rotate slightly counterclockwise. After the positioning portion 221 passes the positioning block 13, the positioning block 13 rebounds back to its original position due to the action of the second torsion spring 14.

[0047] Then the rotating disk 4 rotates counterclockwise, so that the positioning portion 221 abuts against the end of the positioning block 13 again. When the position of the rotating disk 4 is locked, the positioning portion 221 is again limited between the positioning block 13 and the first limiting column 24.

[0048] Optionally, the cutting assembly 3 further includes a second connecting rod 32, a third torsion spring 33 and a second limiting column 34, one end of the second connecting rod 32 is fixedly connected to the cutting knife 31, a second mounting column 35 is provided on the second connecting rod 32, the third torsion spring 33 is sleeved on the second mounting column 35, and the torsion arms at both ends of the third torsion spring 33 respectively abut the second limiting column 34 and the second connecting rod 32, so that the cutting knife 31 can press against the surface of the tree trunk.

[0049] like Figure 3 As shown, in this embodiment, the cutting assembly 3 and the fastening assembly 2 are respectively fixed on the left and right sides of the rotating disk 4. When the rotating disk 4 rotates, the cutting assembly 3 and the fastening assembly 2 rotate together, so that the cutting knife 31 and the first abutment member 23 perform ring cutting on the trunk during the rotation process, and always maintain a stable clamping effect during the ring cutting process, so that the trunk position is stable.

[0050] During the ring cutting process, because the surface of the trunk is uneven, the trunk will give the cutter 31 a radial outward repulsive force. The elastic force of the third torsion spring 33 can counteract the repulsive force brought by the trunk, so that the cutter 31 is always pressed against the surface of the trunk, making the ring cutting effect more stable.

[0051] Optionally, the cutting assembly 3 further includes a second abutment 36 and a connecting seat 37, the second abutment 36 being suitable for abutting the tree trunk in the cutting cavity 11, the connecting seat 37 simultaneously fixedly connecting the second connecting rod 32 and the second abutment 36, the cutting knife 31 being fixed on the connecting seat 37, and the second abutment 36 and the first connecting rod 22 cooperating to clamp the tree trunk in the cutting cavity 11.

[0052] like Figure 3 As shown, in this embodiment, the second abutment 36 is bow-shaped, and the cutting knife 31 is arranged above the second abutment 36. The second abutment 36 cooperates with the first abutment 23 to clamp the tree trunk from both ends of the cutting cavity 11, and further cooperates with the cutting knife 31 to always maintain a stable clamping effect on the tree, effectively improving the cutting effect under complex cutting conditions.

[0053] Optionally, the cutting assembly 3 further includes a third connecting rod 38, the ends of which are fixedly connected to the second mounting post 35 and the connecting seat 37, respectively. The torsion arms at both ends of the third torsion spring 33 abut against the second limiting post 34 and the side wall of the connecting seat 37, respectively. The third connecting rod 38 is adapted to abut against the cutting blade 31 to make the connection structure more stable.

[0054] When the fruit tree ring cutting machine is in use, the tree enters the cutting chamber 11 through the tree clamping mouth 41. After the user puts the cutting knife 31 against the surface of the tree, the device is started. At this time, the rotating disk 4 drives the cutting component 3 and the fastening component 2 to rotate around the cutting chamber 11. The cutting knife 31 gradually cuts into the bark as it rotates. After one circle of rotation, the bark falls off, thereby completing the ring cutting operation on the tree.

[0055] Because the fastening assembly 2 and the cutting assembly 3 are positioned lateral to each other relative to the cutting chamber 11, the tree is confined within a certain range of motion by the combined action of the two, thereby improving the stability of the equipment during cutting. Secondly, the first connecting rod 22 and the first abutment member 23 in the fastening assembly 2 can be rotatably connected to abut against the tree surface, thereby better conforming to the uneven surface of the tree and further improving the abutment effect. Furthermore, when the cutting depth of the cutting assembly 3 changes during the ring cutting process (e.g., increases or decreases), the first connecting rod 22 drives the first abutment member 23 to adjust its position along the tree surface, thereby dynamically changing the clamping radius. This ensures that the fastening assembly 2 can adapt to changes in cutting depth in real time and, together with the cutting assembly 3, always maintains a stable clamping effect on the tree, effectively improving the cutting effect under complex cutting conditions.

[0056] Optionally, the fruit tree ring cutting machine also includes a transmission assembly 6, which includes a first bevel gear 61, a second bevel gear 62, a driving wheel 63 and several first driven wheels 64. The driving member 5 is connected to the first bevel gear 61 and drives the first bevel gear 61 to rotate. The first bevel gear 61 and the second bevel gear 62 are meshed and connected. The driving wheel 63 and the second bevel gear 62 are coaxially connected. The first driven wheel 64 is distributed on both sides of the driving wheel 63 and is transmission-connected to the driving wheel 63. The rotating disk 4 is provided with an external tooth portion 44. The first driven wheel 64 is meshed and connected with the external tooth portion 44 to drive the rotating disk 4 to rotate.

[0057] The first driven wheel 64 can be directly meshed and connected with the driving wheel 63, or can be connected to the driving wheel 63 through a transmission chain, a transmission belt, etc.

[0058] like Figure 5 and 7 As shown, in this embodiment, a plurality of convex teeth are provided on the outer tooth portion 44, the driving member 5 is a motor or a reducer, and the cutting assembly 3 is connected to the rotating disk 4. The user puts the cutting assembly 3 against the surface of the tree and starts the machine. At this time, the rotating disk 4 drives the cutting assembly 3 to rotate around the trunk, and the cutting assembly 3 gradually cuts into the bark as it rotates, thereby realizing the ring cutting of the tree.

[0059] Compared with the prior art, when in use, after the tree trunk is placed in the rotating disk 4, the driving member 5 is turned on to work, and the driving member 5 drives the first bevel gear 61 to rotate. The first bevel gear 61 changes the direction of power transmission through the cooperation of the second bevel gear 62 to drive the driving wheel 63 to rotate. The first driven wheel 64 evenly shares the power transmitted by the driving wheel 63, effectively reducing the eccentric load phenomenon caused by uneven force on one side of the rotating disk 4, thereby avoiding the offset or irregular movement caused by excessive force on one side during the ring cutting process, making the ring cutting line more uniform; at the same time, it avoids vibration or wear problems caused by eccentric loads, and improves the balance and stability of the equipment operation.

[0060] Optionally, the transmission assembly 6 also includes a second driven wheel 65 and a third driven wheel 66, the first driven wheel 64 is simultaneously meshed and connected to the outer tooth portion 44 and the second driven wheel 65, the third driven wheel 66 is simultaneously meshed and connected to the second driven wheel 65 and the driving wheel 63, and the driving wheel 63 drives the rotating disk 4 to rotate by sequentially transmitting the third driven wheel 66, the second driven wheel 65, and the first driven wheel 64.

[0061] like Figure 7As shown, in this embodiment, the second driven wheel 65 and the third driven wheel 66 do not contact the rotating disk 4, and the first driven wheel 64 and the driving wheel 63 are connected by the second driven wheel 65 and the third driven wheel 66, so that the transmission structure is more stable and less likely to break than a transmission chain or a transmission belt.

[0062] There are two first driven wheels 64, two second driven wheels 65, and two third driven wheels 66, which are symmetrically distributed on the left and right sides of the driving wheel 63 and arranged in combination with the driving wheel 63 to form a U-shape. The U-shaped structure can adapt to the arc shape of the rotating disk 4, thereby reducing the space occupied by the transmission wheel assembly without affecting the rotation of the rotating disk 4, making the internal structure of the fruit tree ring cutting machine more compact.

[0063] When the driving wheel 63 rotates forward, the third driven wheel 66 rotates in the reverse direction, the second driven wheel 65 rotates forward, the first driven wheel 64 rotates in the reverse direction, and the rotating disk 4 rotates forward, so that the driving wheel 63 and the rotating disk 4 rotate in the same direction, which facilitates control. The forward direction is clockwise or counterclockwise, and the reverse direction is the opposite of the forward direction.

[0064] Optionally, a first bearing and a retaining ring are sleeved on the axle of the first bevel gear 61 , a limiting groove is recessed on the axle of the first bevel gear 61 , the retaining ring is limited in the limiting groove, and the retaining ring is axially limited to the first bearing.

[0065] like Figure 7 As shown, in this embodiment, there are two first bearings. The first bearings are used to reduce the friction during the rotation of the first bevel gear 61, making the rotation smoother. The retaining ring is axially limited to the first bearing, which can prevent the first bearing from falling off or axially sliding during rotation, making the structure more stable.

[0066] Optionally, the transmission assembly 6 further includes a driving shaft 631 , through which the second bevel gear 62 and the driving wheel 63 are connected. A second bearing is sleeved on the driving shaft 631 , and the upper and lower ends of the second bearing respectively abut against the driving wheel 63 and the second bevel gear 62 .

[0067] like Figure 5 As shown, in this embodiment, there are two second bearings, and the two second bearings can reduce the friction between the second bevel gear 62 and the driving wheel 63 when they rotate. At the same time, the second bearings support the driving wheel 63, and can increase the distance between the driving wheel 63 and the second bevel gear 62, so that the first bevel gear 61 can be located between the driving wheel 63 and the second bevel gear 62, making the structure more compact without affecting the rotation.

[0068] Optionally, the fruit tree ring cutter also includes a reduction assembly 7, a connecting shell 8 and a transmission assembly 6. The reduction assembly 7 is accommodated in the connecting shell 8 and rotates in the connecting shell 8. The reduction assembly 7 includes a first rotating seat 71, a first sun gear 72 and several first planetary gears 73. The driving member 5 is connected to the first sun gear 72 and drives the first sun gear 72 to rotate. The first planetary gears 73 are distributed around the first sun gear 72 and are meshed with the first sun gear 72. The first planetary gears 73 are connected to the first rotating seat 71 and drive the first rotating seat 71 to rotate. An inner tooth portion 81 is protruding from the inner wall of the connecting shell 8. The first planetary gear 73 is meshed with the inner tooth portion 81. The first rotating seat 71 is connected to the transmission assembly 6 and drives the transmission assembly 6 to rotate, so that the torque increases and the speed decreases.

[0069] like Figure 8 and 9 As shown, in this embodiment, the inner tooth portion 81 and the connecting shell 8 are integrally formed. The inner tooth portion 81 provides a rolling track for the first planetary gear 73. The first planetary gear 73 rotates around the inner tooth portion 81 while rotating around the first sun gear 72. There are three first planetary gears 73, and they are evenly distributed around the first sun gear 72 with the first sun gear 72 as the center. Three connecting shafts are protruding from one end of the first rotating seat 71 near the first planetary gear 73. The connecting shafts are connected to the wheel axles of the first planetary gear 73. When the first planetary gear 73 rotates, the first rotating seat 71 is driven to rotate together through the connecting shafts. The first sun gear 72 and the first planetary gear 73 cooperate to achieve the first stage of reduction.

[0070] By setting up the reduction assembly 7, the driving member 5 increases the torque and reduces the rotational speed in cooperation with the first sun gear 72 and the first planetary gear 73, so that the rotational speed finally output to the transmission assembly 6 is smaller, and the trunk ring cutting can be performed more stably.

[0071] Optionally, the reduction assembly 7 further includes a second rotating seat 74 and a plurality of second planetary gears 75. The second planetary gears 75 are connected to the second rotating seat 74 and drive the second rotating seat 74 to rotate. A second sun gear 76 is protruded from one end of the first rotating seat 71 away from the first sun gear 72. The second planetary gears 75 are distributed around the second sun gear 76 and meshed with the second sun gear 76. The second planetary gears 75 are meshed with the inner tooth portion 81.

[0072] The reduction assembly 7 also includes a third rotating seat 77 and several third planetary gears 78. The third planetary gears 78 are connected to the third rotating seat 77 and drive the third rotating seat 77 to rotate. A third sun gear 79 is protruded from the end of the second rotating seat 74 away from the second sun gear 76. The third planetary gears 78 are distributed around the third sun gear 79 and are meshed with the third sun gear 79. The third planetary gears 78 are meshed with the inner tooth portion 81.

[0073] The second sun gear 76 and the first rotating seat 71 are integrally formed, and the axle of the second sun gear 76 and the axle of the first sun gear 72 are located on the same straight line. There are three second planetary gears 75, and they are evenly distributed around the second sun gear 76 with the second sun gear 76 as the center. When the first planetary gear 73 drives the first rotating seat 71 to rotate, the second sun gear 76 drives the second planetary gear 75 to rotate. While the second planetary gear 75 rotates around the second sun gear 76, it also rotates around the inner tooth portion 81. The second rotating seat 74 is protruding with three connecting shafts at one end near the second planetary gear 75. The connecting shafts are connected to the axle of the second planetary gear 75. When the second planetary gear 75 rotates, it drives the second rotating seat 74 to rotate together through the connecting shafts. The second sun gear 76 and the second planetary gear 75 cooperate to achieve the second stage of reduction.

[0074] The third sun gear 79 and the second rotating seat 74 are integrally formed, and the axle of the third sun gear 79 is located on the same straight line as the axle of the second sun gear 76. There are three third planetary gears 78, which are evenly distributed around the third sun gear 79 with the third sun gear 79 as the center. When the second planetary gear 75 drives the second rotating seat 74 to rotate, the third sun gear 79 drives the third planetary gear 78 to rotate. While the third planetary gear 78 rotates around the third sun gear 79, it also rotates around the inner tooth portion 81. Three connecting shafts are protruding from one end of the third rotating seat 77 near the third planetary gear 78. The connecting shafts are connected to the axle of the third planetary gear 78. When the third planetary gear 78 rotates, it drives the third rotating seat 77 to rotate together through the connecting shafts. The third sun gear 79 and the third planetary gear 78 cooperate to achieve the third stage of reduction.

[0075] The driving member 5 decelerates in sequence through the first stage deceleration, the second stage deceleration, and the third stage deceleration, so that the rotational speed finally output to the transmission assembly 6 decreases step by step and eventually approaches the preset value, thereby enabling more stable trunk girdling.

[0076] The housing 1 is formed with a handle for the user to grasp. The handle extends parallel to or in the same plane as the opening of the tree clamping opening 41. The battery, drive member 5, and reduction assembly 7 are all accommodated in the handle, and a plug-in port compatible with the battery is provided on the handle. This design not only improves the internal space utilization of the housing 1 but also makes the force distribution more uniform when the user grasps it, effectively reducing fatigue during use. It also conforms to ergonomic principles, improves operational comfort and stability, and meets the needs of actual use scenarios.

[0077] Optionally, the fruit tree ring cutter also includes a clamping assembly 9, which is connected to the casing 1. The clamping assembly 9 includes a pair of claws 91 symmetrically arranged relative to the cutting chamber 11, and the side of the claw 91 close to the cutting chamber 11 is arc-shaped to facilitate clamping of trees. The side of the claw 91 close to the cutting chamber 11 is connected to a plurality of pulleys 92, and the pulleys 92 are suitable for sliding connection with the tree trunk. A connecting column 93 is provided on the claw 91, and a spring 94 is provided on the connecting column 93. A connecting groove 16 is provided in the casing 1, and the two ends of the spring 94 respectively abut the side walls of the claw 91 and the connecting groove 16 to make the claw 91 and the casing 1 elastically and movably connected.

[0078] like Figure 7 As shown, the clamping assembly 9 is arranged below the rotating disk 4 and does not rotate. The two claws 91 cooperate with each other to stabilize the position of the tree trunk in the cutting cavity 11 without affecting the rotation of the rotating disk 4.

[0079] Multiple pulleys 92 are arranged in sequence along the edges of the clamping jaws 91, with at least a portion of the pulleys 92 protruding from the edges of the clamping jaws 91. The design of the pulleys 92 not only effectively reduces friction when the tree enters the auxiliary clamping portion, but also better adapts to the uneven surface of the tree. The design of the pulleys 92 not only effectively reduces friction when the tree enters the clamping assembly 9, but also flexibly adapts to the unevenness of the tree's surface, thereby further enhancing the clamping effect.

[0080] Another embodiment of the present invention provides a ring cutting method, including the fruit tree ring cutting machine as described above, and also including a control component, the control component and the drive member 5 are electrically connected, the control component includes a stall detection device, when the preset condition of the stall detection device is not triggered, the drive member 5 drives the rotating disk 4 to rotate forward; when the preset condition of the stall detection device is triggered, the control component determines that the rotating disk 4 is in a stalled state, and the drive member 5 drives the rotating disk 4 to rotate in the opposite direction, so that the cutting knife 31 retreats to the cutting groove already formed on the trunk, thereby ensuring that the stuck cutting knife 31 can be pulled out smoothly, while also preventing the tree from being further damaged.

[0081] The stall detection device can be a common sensing control device such as a current sensor, a voltage sensor, a torque sensor, etc., and the preset condition can be when the actual parameter value (voltage, voltage, torque, etc.) is greater than or equal to the preset parameter value.

[0082] Furthermore, the control component further includes a time control device having a built-in reverse control time. When a preset condition of the stall detection device is triggered, the driving member 5 drives the rotating disk 4 to rotate in the reverse direction for the reverse control time, and then the control component controls the driving member 5 to stop rotating.

[0083] Preferably, the reversal time is controlled within 0.2-0.3 seconds to avoid excessive reversal. In this way, when a stall is detected, the reversal logic will be executed according to the time built into the time control device, so that the reversal action of the fruit tree ring cutting machine can be controlled within a certain range, ensuring the controllability of the fruit tree ring cutting machine.

[0084] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present invention.
