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] Ring cutting (also known as girdling) is a technique for making circular cuts on branches and trunks during the growth period of fruit trees. By peeling off the bark between the two blades and exposing the wood, ring cutting can temporarily hinder the downward transport of organic matter, reduce the nutrient supply of the root system, and promote the accumulation of nutrients above the peeling, thereby effectively inhibiting nutrient growth, promoting flower bud differentiation, and significantly improving fruit quality. The existing electric ring cutting equipment has the following problems in practical applications: due to the inconsistent hardness and surface flatness of the bark at various locations (such as the greater unevenness and harderness of the knot area), the actual cutting force during the ring cutting process is often unstable, and the equipment is prone to vibration and deviation, resulting in excessive cutting depth of the tool, motor stalling, or insufficient cutting depth, and the bark cannot be completely peeled off. The above problems not only significantly reduce the work efficiency of the ring cutting operation, but may also cause unnecessary damage to the fruit trees, limiting the promotion and application of electric ring cutting technology.

[0037] The embodiment of the present invention provides a fruit tree ring cutting machine, combined with Figure 1-9As shown, it includes a casing 1, a rotating disk 4, a fastening assembly 2, a cutting assembly 3, and a driving member 5.

[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 against a 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 against the tree trunk.

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

[0040] like Figure 6 As 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 so that the rotating disk 4 rotates around the cutting cavity 11 to perform trunk girdling. The side of the first connecting rod 22 close to the cutting cavity 11 is arc-shaped and suitable for abutting the 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 trunk. The abutting portion 232 is approximately in the shape of a water drop to increase the pressure at the end of the water drop to make the abutting effect more stable.

[0041] A connecting portion 231 is provided at one end of the first abutting member 23, and the connecting portion 231 is provided at one end of the first abutting member 23 away from the abutting portion 232. A connecting hole 223 is provided at one end of the first connecting rod 22 away from the connecting portion 231. 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 tree 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 member 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 abut against the positioning seat 12 and the positioning block 13 respectively. A positioning portion 221 is convexly provided at one end of the first connecting rod 22, and the positioning portion 221 is suitable for abutting 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 convexly provided with a limit block 222, the first limit column 24 is arranged 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 located 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 to press against the tree trunk.

[0044] like Figure 2 As shown, in this embodiment, one 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 cavity 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 squeezed, and 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 close to the cutting cavity 11. When the fastening assembly 2 is in the initial position, the positioning portion 221 is limited between the first stop column 24 and the positioning block 13 because the rotating disk 4 is locked, and the first torsion spring 43 is in a compressed state. When the rotating disk 4 starts to rotate clockwise, the positioning portion 221 rotates around the cutting cavity 11 with the rotating disk 4 and moves away from the positioning block 13. At this time, the first torsion spring 43 drives the first connecting rod 22 to rotate in a direction away from the positioning block 13 until the stop block 222 abuts against the first stop column 24.

[0046] The side of the positioning block 13 close to the cutting chamber 11 is provided with an arc-shaped guide portion 131, and the guide portion 131 is slidably connected with the positioning portion 221. When the rotating disk 4 rotates one circle, the positioning portion 221 slides over the guide portion 131 and drives the positioning block 13 to rotate slightly counterclockwise through the guide portion 131. When the positioning portion 221 passes the positioning block 13, the positioning block 13 rebounds back to its original position under 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 also 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 the surface of the 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 to stabilize the position of the trunk.

[0050] During the ring cutting process, because the surface of the trunk is uneven, the trunk will give the cutting knife 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 cutting knife 31 is always pressed against the surface of the trunk, making the ring cutting effect more stable.

[0051] Optionally, the cutting assembly 3 also includes a second abutment member 36 and a connecting seat 37, the second abutment member 36 is suitable for abutting against the tree trunk in the cutting cavity 11, the connecting seat 37 simultaneously fixes the second connecting rod 32 and the second abutment member 36, the cutting knife 31 is fixed on the connecting seat 37, and the second abutment member 36 and the first connecting rod 22 cooperate to clamp the tree trunk in the cutting cavity 11.

[0052] like Figure 3 As shown, in this embodiment, the second abutment member 36 is bow-shaped, and the cutting knife 31 is arranged above the second abutment member 36. The second abutment member 36 cooperates with the first abutment member 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, thereby effectively improving the cutting effect under complex cutting conditions.

[0053] Optionally, the cutting assembly 3 further includes a third connecting rod 38, the two ends of which are respectively fixedly connected to the second mounting column 35 and the connecting seat 37, and the two end torsion arms of the third torsion spring 33 respectively abut against the second limiting column 34 and the side wall of the connecting seat 37. The third connecting rod 38 is suitable for abutting against the cutting knife 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] Since the fastening assembly 2 and the cutting assembly 3 are arranged left and right relative to the cutting chamber 11, the tree is restricted within a certain range of movement under the joint action of the two, thereby improving the stability of the equipment during cutting; secondly, the first connecting rod 22 and the first abutment 23 in the fastening assembly 2 can be connected by rotation and abut against the tree surface together, thereby better fitting the uneven surface of the tree and further improving the abutment effect; further, when the cutting depth of the cutting assembly 3 changes during the ring cutting process (such as increasing or decreasing), the first connecting rod 22 will drive the first abutment 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 the change of the cutting depth in real time, and cooperate with the cutting assembly 3 to always maintain 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 a plurality of 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 and the external tooth portion 44 are meshed and connected 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 transmission-connected with 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 unbalanced 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 meshed and connected to the outer tooth portion 44 and the second driven wheel 65 at the same time, the third driven wheel 66 is meshed and connected to the second driven wheel 65 and the driving wheel 63 at the same time, 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 are arranged in combination with the driving wheel 63 to form a U shape. The U-shaped structure can be adapted 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 backward, the second driven wheel 65 rotates forward, the first driven wheel 64 rotates backward, and the rotating disk 4 rotates forward, so that the driving wheel 63 and the rotating disk 4 rotate in the same direction, which is convenient for control. The forward direction is clockwise or counterclockwise, and the reverse direction is the opposite direction to 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, which are used to reduce the friction of the first bevel gear 61 during rotation, 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 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 the present 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 a plurality of 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 meshingly connected 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 convexly provided on the inner wall of the connecting shell 8. The first planetary gear 73 is meshingly connected 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, and 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 close to the first planetary gear 73, and 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 providing the reduction assembly 7, the driving member 5 can increase the torque and reduce the rotation speed under the cooperation of the first sun gear 72 and the first planetary gear 73, so that the rotation 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, wherein 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 convexly provided at 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 meshedly connected to the second sun gear 76, and the second planetary gears 75 are meshedly connected to the inner tooth portion 81;

[0072] The reduction assembly 7 also includes a third rotating seat 77 and a plurality of 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 one 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 meshingly connected with the third sun gear 79. The third planetary gears 78 are meshingly connected 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 close to 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, the second rotating seat 74 is driven 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 and the axle of the second sun gear 76 are located on the same straight line. There are three third planetary gears 78, and they 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 convexly provided at one end of the third rotating seat 77 close to 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, the third rotating seat 77 is driven 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 rotation speed finally output to the transmission assembly 6 is gradually reduced and finally approaches a preset value, thereby enabling more stable trunk girdling.

[0076] The housing 1 is formed with a handle for the user to hold, and the extension direction of the handle is parallel to or in the same plane as the opening direction of the tree clamping opening 41. The battery, the driving member 5 and the deceleration assembly 7 can all be accommodated in the handle, and a plug interface compatible with the battery is provided on the handle. This design not only makes the internal space utilization of the housing 1 higher, but also makes the force distribution more uniform when the user holds it, effectively reducing the fatigue during use, and at the same time is more in line with ergonomic principles, improving the comfort and stability of operation, and meeting 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 tree trunks. A connecting column 93 is provided on the claw 91, and a spring 94 is sleeved 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 against the side walls of the claw 91 and the connecting groove 16 to elastically and movably connect the claw 91 and the casing 1.

[0078] like Figure 7 As shown, the clamping assembly 9 is arranged below the rotating disk 4 and does not rotate, and 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] A plurality of pulleys 92 are arranged in sequence along the edge of the claw 91, and the pulleys 92 are at least partially protruding from the edge of the claw 91. The design of the pulleys 92 can reduce the friction when the tree enters the auxiliary clamping portion, and can better adapt to the uneven surface of the tree. The design of the pulleys 92 can not only effectively reduce the friction when the tree enters the clamping assembly 9, but also flexibly adapt to the uneven characteristics of the tree 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, wherein the control component is electrically connected to the drive member 5, and 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 stall 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 that has been formed on the trunk, thereby ensuring that the stuck cutting knife 31 can be pulled out smoothly, while also protecting the tree from further damage.

[0081] The stall detection device may be a common sensing control device such as a current sensor, a voltage sensor, a torque sensor, etc., and the preset condition may 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 comprises a time control device, wherein the time control device has a built-in reverse control time. When the 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 reversing time is controlled within 0.2-0.3 seconds, thereby avoiding excessive reversing. In this way, when a stall is detected, the reversing logic will be executed according to the time built into the time control device, so that the reversing 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 disclosure is disclosed as above, the protection scope of the 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 disclosure, and these changes and modifications will fall within the protection scope of the present invention.
