Description

Technical Field

[0001] The invention relates to the technical field of willow stem propagation, in particular to a reciprocating willow mobile sawing machine and a use method thereof. Background Art

[0002] Willow, a general term for plants in the genus Salix in the family Salicaceae, is known for its slender branches, making it a highly ornamental plant and a frequent subject of poetry and prose by ancient scholars. Willow branches are crucial for asexual reproduction, and gardeners often cut them and insert them into the soil for propagation.

[0003] In order to improve the efficiency of inserting poles, gardeners usually cut a large number of willow branches at one time and use a mobile saw to cut them into appropriate lengths for inserting poles. Most existing saws consist of a workbench and a blade driven by a motor, and the branches are cut by the rotating motion of the blade. However, the rich cellulose fibers inside the willow branches make them more flexible. When the blade cuts the willow branches, the fiber "drawing" phenomenon is prone to occur. At this time, the high-speed rotating blade will hook the fibers that have not been completely cut, causing the willow branches to entangle the blade and cause the blade to get stuck. This will not only cause the motor to overload, but may also cause the blade teeth to break due to abnormal force, posing an obvious safety hazard.

[0004] Furthermore, fiber stringing, resulting in burrs on the cut surface, also severely limits the success rate of cuttings. These burrs can easily tear newly formed callus cells during subsequent handling or soil insertion, creating pathways for pathogens (such as fungi and bacteria) to invade the xylem. This often leads to systemic decay in the willow branches, significantly reducing the survival rate of cuttings.

[0005] Therefore, there is an urgent need for a mobile willow saw that can effectively suppress burrs from forming on willow cuts and prevent willow fibers from entangled with and blocking blades. Summary of the Invention

[0006] The present invention provides a reciprocating mobile willow saw and a method for using the same. The upper and lower turntables are driven to rotate coaxially and in opposite directions by a bidirectional rotation mechanism. Abutment assemblies and cutting assemblies provided on the upper and lower turntables cooperate to generate bidirectional torsional shear forces at the cut portion of the willow branches, thereby concentrating stress at the cut portion of the willow branches to reduce the generation of fiber burrs at that portion. This solves the problems in the above-mentioned background art, namely:

[0007] When traditional mobile saws cut willow bundles, due to the high flexibility of the willow branches, many burrs will appear at the cut of the willow branches. These burrs will wrap around the blades and cause the blades to get stuck or even break, posing an obvious safety hazard. In addition, the burrs at the cut of the willow branches will also reduce the survival rate of willow cuttings.

[0008] To achieve the above-mentioned purpose, the reciprocating willow branch mobile sawing machine includes a worktable, the top surface of the worktable is rotatably connected to a lower turntable, the top surface of the lower turntable is coaxially rotatably connected to an upper turntable, the outer surface of the upper turntable is provided with at least two evenly distributed abutment components, the outer surface of the lower turntable is provided with at least two evenly distributed cutting components, and the interior of the worktable is provided with a bidirectional rotation mechanism;

[0009] The bidirectional rotation mechanism is used to drive the lower turntable and the upper turntable to rotate in opposite directions. When cutting willow branches, the abutment assembly applies opposite abutment forces to the upper and lower sides of the cut part of the willow branch to fix the willow branch. At the same time, the cutting assembly rotates synchronously in the opposite direction to apply cutting force to cut off the cut part of the willow branch, thereby forming a bidirectional torsional shear force at the cut part of the willow branch, concentrating internal stress to reduce the risk of fiber burrs and entanglement.

[0010] In the above technical solution, when the bidirectional rotation mechanism is in operation, the lower turntable and the upper turntable rotate in opposite directions on the same axis, thereby causing the abutting assembly and the cutting assembly to move in opposite directions. When the abutting assembly and the cutting assembly contact the willow branch, the abutting assembly applies abutting forces to the upper and lower sides of the cut portion of the willow branch, and the cutting assembly applies cutting forces in opposite directions to the cut portion of the willow branch. Through the two forces acting in opposite directions, a bidirectional torsional shear force can be formed at the cut portion of the willow branch, thereby concentrating the internal stress generated by the willow branch fibers, preventing the willow branch fibers from tearing, making the incision of the willow branch smoother, and reducing burrs, thereby effectively preventing burrs from entangled with the blade during the cutting process of the willow branch, and reducing safety hazards during operation.

[0011] At the same time, reducing the fiber burrs at the willow branch incision can also make the willow branch incision smoother, which is conducive to the healing of the incision by callus tissue cells at the willow branch incision, and can reduce the invasion of pathogens in the willow branch xylem, thereby improving the survival rate of willow branch cutting propagation.

[0012] In addition, the abutment assembly and the cutting assembly are evenly arranged on the lower turntable and the upper turntable respectively. When the lower turntable and the upper turntable rotate coaxially in opposite directions, at least two cutting stations with overlapping positions when viewed from above are formed, which are used to perform multiple groups of willow branch cutting operations at the same time, thereby improving the working efficiency of the device in processing willow branches.

[0013] On this basis, the abutment assembly and the cutting assembly are evenly arranged on the lower turntable and the upper turntable respectively, and when the lower turntable and the upper turntable rotate coaxially and in opposite directions, at least two cutting stations with overlapping positions when viewed from above are formed, so as to perform multiple groups of willow branch cutting operations simultaneously;

[0014] The abutment assembly includes a mounting rod fixedly connected to the outside of the upper turntable, an abutment frame fixedly connected to one end of the mounting rod away from the upper turntable, and a cutting opening is opened on one side of the abutment frame; the overall shape of the abutment frame is arc-shaped, and it is used to abut against the willow branches gathered into a bundle over a large area to evenly distribute the abutment force and provide stable support during cutting;

[0015] The cutting assembly includes a telescopic rod fixedly connected to the outside of the lower rotating disk, and a cutter is fixedly connected to one end of the telescopic rod away from the lower rotating disk. After cutting the willow branch, the cutter can pass through the cutting opening;

[0016] A spring is provided inside the telescopic rod, a limit rod is fixedly connected to the outside of the telescopic rod, and at least two evenly distributed limit plates are fixedly connected to the bottom surface of the upper turntable;

[0017] A wave groove is provided on one side of the limit plate close to the limit rod. The wave groove alternately abuts against the limit rod through wave troughs and wave crests, and drives the telescopic rod to reciprocate under the elastic reset action of the spring, so that the cutter can achieve horizontal sawing movement to concentrate the stress on the cutting part and minimize burr generation.

[0018] In this technical solution, the telescopic end of the telescopic rod is continuously extended and retracted through the limiting effect of the wave groove on the limiting plate and the elastic resetting effect of the spring, so that the cutter is continuously moved in the horizontal direction to achieve a sawing effect, further improving the cutting effect of the cutter, and further ensuring the stress concentration of the cutting part of the willow branch, effectively avoiding the appearance of more burrs in the cutting part of the willow branch after cutting.

[0019] The present invention also provides a method for using a reciprocating mobile willow saw, which is applied to any of the above-mentioned reciprocating mobile willow saws, and comprises the following steps:

[0020] S1. First, the staff gathers the willow branches to be cut into a bundle and fixes the bundle with two conveyor rods. Then, the drive motor is started, driving the two meshing gears to drive the conveyor rods to rotate forward, transporting the bottom end of the bundle to the discharge port, ensuring that both ends of the willow branches are restrained to prevent shaking during cutting;

[0021] S2. Afterwards, the staff activates the driving element of the bidirectional rotation mechanism, which drives the lower turntable and the upper turntable to rotate synchronously in opposite directions through the meshing transmission of the No. 1 bevel gear, the auxiliary bevel gear, and the No. 2 bevel gear. During this process, the abutment frame of the abutment assembly applies opposing abutment forces to the upper and lower sides of the willow branch cutting part to fix the willow branch. The cutter of the cutting assembly moves synchronously in the opposite direction, forming a bidirectional torsional shear force with the abutment force, concentrating internal stress to reduce fiber tearing. During the rotation of the turntable, the limit rod contacts the wave groove limit plate at the bottom of the upper turntable. The wave crest of the wave groove pushes the limit rod, causing the telescopic rod to extend and stretch the spring. The spring at the wave trough resets and contracts, driving the cutter to retract, forming a reciprocating sawing motion;

[0022] S3. After the cutting is completed, the cut part of the willow branch falls into the inside of the workbench from the discharge port as waste and is automatically transported to the outside of the workbench by the conveyor belt. The remaining willow branch body remains on the top surface of the workbench as the raw material for propagation of plugs. Finally, the staff drives the motor to reverse and drives the conveying rod to rotate upward through the gear to lift the remaining willow branch raw materials. After the staff removes the remaining willow branches, they can re-bind new willow branch bundles.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In this reciprocating willow branch mobile saw and its use method, a bidirectional rotating mechanism drives the lower turntable and the upper turntable to rotate synchronously in opposite directions, so that the abutment component applies abutment force to the upper and lower sides of the willow branch cutting part. At the same time, the cutting component moves in the opposite direction to apply cutting force, forming a bidirectional torsional shear force. This design concentrates the internal stress of the willow branch fiber, avoids fiber tearing, and significantly reduces the formation of incision burrs. After the burrs are reduced, the phenomenon of fiber entanglement with the cutter during the cutting process is fundamentally avoided, and the saw blade tooth breakage, motor overload, and willow branch rebound and flying out are prevented, thereby reducing the safety risks of the device during willow branch cutting.

[0025] At the same time, a smooth incision can prevent burrs from tearing new callus cells, promote rapid healing of willow branch incisions, reduce the channels for pathogens to invade the xylem, reduce the risk of systemic decay, and improve the survival rate of willow cutting propagation;

[0026] In addition, the abutment assembly and the cutting assembly are evenly distributed on the upper turntable and the lower turntable. When the upper turntable and the lower turntable rotate coaxially and in opposite directions, at least two cutting stations that overlap in a top-down perspective are formed, which supports the simultaneous processing of multiple bundles of willow branches, cooperates with the willow branch transport assembly to control the movement of the willow branches, and cooperates with the conveyor belt to deliver the fertilizer out of the workbench, which can simplify the operating steps of the staff and improve the efficiency of the device in cutting willow branches.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] Example 1

[0046] At present, when a traditional mobile saw cuts a willow branch bundle, due to the high flexibility of the willow branch, many burrs will appear at the willow branch incision. These burrs will wrap around the blade and cause the blade to get stuck or even break, which poses an obvious safety hazard. In addition, the burrs at the willow branch incision will also reduce the survival rate of willow branch plug propagation. The present invention provides a reciprocating willow branch mobile saw and its use method, see Figure 1 and Figure 2 As shown, it includes a workbench 1, the top surface of the workbench 1 is rotatably connected to a lower turntable 2, the top surface of the lower turntable 2 is coaxially rotatably connected to an upper turntable 3, the outer portion of the upper turntable 3 is provided with at least two evenly distributed abutment components 4, the outer portion of the lower turntable 2 is provided with at least two evenly distributed cutting components 5, and the interior of the workbench 1 is provided with a bidirectional rotation mechanism 6, which is used to drive the lower turntable 2 and the upper turntable 3 to rotate in opposite directions. When cutting a willow branch, the abutment component 4 applies opposing abutment forces to the upper and lower sides of the cut portion of the willow branch to fix the willow branch, and the cutting component 5 rotates synchronously in the opposite direction to cut off the cut portion of the willow branch;

[0047] Among them, when the bidirectional rotation mechanism 6 is running, the lower turntable 2 and the upper turntable 3 will rotate in opposite directions on the same axis, so that the abutment component 4 and the cutting component 5 move in opposite directions. When the abutment component 4 and the cutting component 5 contact the willow branch, the abutment component 4 applies abutment force to the upper and lower sides of the cutting part of the willow branch, and the cutting component 5 applies cutting force in opposite directions to the cutting part of the willow branch. Through two forces in opposite directions, the stability of the cutting part of the willow branch can be guaranteed while fixing the willow branch, providing a mechanical fulcrum for the cutting action; at the same time, when the abutment component 4 and the cutting component 5 contact the willow branch, they can form a bidirectional torsional shear force at the cutting part of the willow branch, thereby concentrating the internal stress generated by the willow branch fibers, avoiding the tearing of the willow branch fibers, making the incision of the willow branch smoother, and reducing burrs.

[0048] Reducing the generation of fiber burrs at the incision of willow branches can effectively avoid the phenomenon of burrs being entangled with the blade due to the cutting force during the cutting process, thereby effectively preventing the blade from breaking or rebounding the willow branches when cutting highly flexible branches such as willow branches, improving the safety of the device when cutting willow branches, and can also reduce the splashing when cutting willow branches, protecting the operator's eyes or respiratory tract; at the same time, reducing the fiber burrs at the incision of willow branches can also make the incision of willow branches smoother, which is conducive to the healing of the incision by callus tissue cells at the incision of willow branches, and can reduce the invasion of pathogens in the xylem of willow branches, thereby improving the survival rate of willow branch cuttings.

[0049] For details, see Figure 3 and Figure 5 As shown, the abutment assembly 4 includes a mounting rod 41 fixedly connected to the outside of the upper turntable 3, and an abutment frame 42 is fixedly connected to the end of the mounting rod 41 away from the upper turntable 3. A cutting opening 43 is formed on one side of the abutment frame 42; the cutting assembly 5 includes a telescopic rod 51 fixedly connected to the outside of the lower turntable 2, and a cutter 53 is fixedly connected to the end of the telescopic rod 51 away from the lower turntable 2.

[0050] The overall shape of the abutment frame 42 is arc-shaped, so that the staff can gather the willow branches to be cut into a bundle. In this way, when the abutment frame 42 contacts the willow branches, it can abut the bundled willow branches over a large area and ensure that the abutment force applied to the willow branches is evenly distributed. After cutting the willow branches, the cutter 53 can be separated from the abutment frame 42 from the cutting opening 43 and continue to rotate.

[0051] Furthermore, a spring 52 is provided inside the telescopic rod 51, and a limit rod 54 is fixedly connected to the outside of the telescopic rod 51. At least two evenly distributed limit plates 31 are fixedly connected to the bottom surface of the upper turntable 3. The limit plates 31 are generally arc-shaped, and a wave groove is formed on the side close to the limit rod 54.

[0052] When the spring 52 is in a relaxed state, the telescopic rod 51 is at its initial length. At this time, when the upper turntable 3 rotates and the limit plate 31 contacts the limit rod 54, the limit rod 54 is just at the trough of the wave groove on the limit plate 31. Under the abutment of the wave groove, the limit rod 54 gradually approaches its wave crest. At this time, the telescopic end of the telescopic rod 51 extends, and the spring 52 is stretched and generates elastic force. When the limit rod 54 is at the wave crest of the wave groove, the telescopic rod 51 extends to its maximum length. Thereafter, when the limit rod 54 is separated from the wave crest, the elastic force of the spring 52 Under the action of , the telescopic rod 51 and the limit rod 54 reset and enter the trough again to circulate; when the lower turntable 2 and the upper turntable 3 rotate, the wave groove on the limit plate 31 limits the limit rod 54 and the elastic force of the spring 52 resets the telescopic end of the telescopic rod 51 continuously. As a result, the cutter 53 continuously moves in the horizontal direction to achieve a sawing effect, further improving the cutting effect of the cutter 53, and further ensuring the stress concentration at the cutting part of the willow branch, effectively avoiding the appearance of more burrs at the cutting part after the willow branch is cut.

[0053] It should be noted that a redundant distance should be provided in the length of the cutting opening 43 to ensure that the cutter 53 can smoothly pass through the cutting opening 43 when it reciprocates horizontally.

[0054] For further information, see Figure 6 As shown, by evenly arranging two groups of cutting components 5 and abutment components 4 on the lower turntable 2 and the upper turntable 3 respectively, two overlapping positions are formed in the top view of the workbench 1 by utilizing the coaxial and counter-rotating lower turntable 2 and upper turntable 3, so that the overlapping positions form cutting stations, so that the device can use two cutting stations to cut willow branches at the same time, greatly improving the cutting efficiency of the device; and when the cutting components 5 and the abutment components 4 are set to multiple groups, the discharge port 11, the willow branch conveying component 7 and the conveyor belt 8 can also be set to multiple groups, thereby forming more cutting stations to further improve the cutting efficiency of the device.

[0055] See also Figure 2 and Figure 4 As shown, the bidirectional rotation mechanism 6 may adopt the following structure, or may adopt other structures capable of causing the lower turntable 2 and the upper turntable 3 to rotate in opposite directions. The specific structure of the bidirectional rotation mechanism 6 is disclosed below:

[0056] The bidirectional rotation mechanism 6 includes a driving member 61 fixedly arranged inside the workbench 1, the output end of the driving member 61 is transmission-connected to the No. 1 bevel gear 62, the outside of the No. 1 bevel gear 62 is meshed with an auxiliary bevel gear 63, the outside of the auxiliary bevel gear 63 is meshed with a No. 2 bevel gear 64, the No. 1 bevel gear 62 and the No. 2 bevel gear 64 are symmetrically distributed on the upper and lower sides of the auxiliary bevel gear 63, respectively, the top of the No. 1 bevel gear 62 is fixedly connected to a connecting rod 621, the top of the No. 2 bevel gear 64 is fixedly connected to a connecting cylinder 641, the top of the connecting cylinder 641 is fixedly connected to the bottom surface of the lower turntable 2, the top of the connecting rod 621 passes through the interior of the No. 2 bevel gear 64 and the connecting cylinder 641, and is fixedly connected to the bottom surface of the upper turntable 3;

[0057] Among them, the driving member 61 adopts a chain transmission structure to drive the No. 1 bevel gear 62 to rotate. The chain transmission structure is an existing technology and will not be described in detail here. The rotation of the No. 1 bevel gear 62 is transmitted through the auxiliary bevel gear 63, so that the No. 2 bevel gear 64 rotates in the opposite direction of the rotation of the No. 1 bevel gear 62, thereby causing the lower turntable 2 and the upper turntable 3 to rotate in opposite directions.

[0058] For further information, see Figure 7 As shown, at least two discharge ports 11 are formed on the top surface of the workbench 1. The two discharge ports 11 are respectively located at the overlapping positions of the abutment frame 42 and the cutter 53 when viewed from above during the rotation process. After the abutment assembly 4 and the cutting assembly 5 complete cutting of the willow branches, the cut willow branches will fall from the discharge ports 11 into the interior of the workbench 1. At least two conveyor belts 8 are also provided inside the workbench 1. The two conveyor belts 8 are used to transport the willow branches falling from the discharge ports 11 to the outside of the workbench 1.

[0059] For further information, see Figure 8 As shown, a willow branch conveying assembly 7 is provided on one side of the discharge port 11, which is used to fix the willow branches gathered into bundles and transport the willow branches toward the discharge port 11; the willow branch conveying assembly 7 includes a mounting plate 71 fixedly connected to the top surface of the workbench 1, and a driving motor 72 is fixedly connected to the side of the mounting plate 71 away from the lower turntable 2. The side of the mounting plate 71 away from the lower turntable 2 is rotatably connected to two mutually meshing gears 73, and the driving motor 72 is transmission-connected to one of the gears 73. The side of the mounting plate 71 close to the lower turntable 2 is rotatably connected to two conveying rods 74, and one end of the two conveying rods 74 is fixedly connected to one side of the two gears 73 respectively;

[0060] The two transport rods 74 are used to fix the willow branches gathered into a bundle. When the drive motor 72 is started, the two meshing gears 73 cause the two transport rods 74 to rotate in opposite directions. Under the action of friction, the two transport rods 74 move the willow branches toward the discharge port 11 or away from the discharge port 11. The two transport rods 74 and the discharge port 11 further limit the upper and lower ends of the willow branches in the bundle, which can more effectively prevent the willow branches from shaking significantly at both ends during cutting, thereby further preventing the willow branches from being entangled with the cutter 53 during cutting.

[0061] The conveying rod 74 conveys one end of the willow branch to the cutting station. After the willow branch is cut, the cut willow branch falls onto the conveyor belt 8 along the discharge port 11 as waste and is transported to the outside of the workbench 1 by the conveyor belt 8. The willow branch located on the top surface of the workbench 1 is used as the raw material for propagation by plugging. The staff starts the driving motor 72 to reverse, so that the conveying rod 74 reverses and transports the willow branch upward. After the willow branch is separated from the conveying rod 74, the staff can remove the willow branch and recycle it in a unified manner.

[0062] Example 2

[0063] The present invention also provides a method for operating the reciprocating mobile willow saw in Example 1, comprising the following steps:

[0064] Step 1: First, the staff gathers the willow branches to be cut into a bundle and fixes the bundle of willow branches through two conveying rods 74. Then, the driving motor 72 is started to drive the two meshing gears 73 to drive the conveying rods 74 to rotate forward, and the bottom end of the willow branch bundle is conveyed to the discharge port 11, ensuring that both ends of the willow branches are restrained to avoid shaking during cutting;

[0065] Step 2. After that, the staff starts the driving part 61 of the bidirectional rotation mechanism 6, and drives the lower turntable 2 and the upper turntable 3 to rotate synchronously in opposite directions through the meshing transmission of the No. 1 bevel gear 62, the auxiliary bevel gear 63 and the No. 2 bevel gear 64. During this process, the abutment frame 42 of the abutment assembly 4 applies abutment forces on the upper and lower sides of the willow branch cutting part to fix the willow branch. The cutter 53 of the cutting assembly 5 moves synchronously in the opposite direction, forming a bidirectional torsional shear force with the abutment force, concentrating internal stress to reduce fiber tearing. During the rotation of the turntable, the limit rod 54 contacts the wave groove limit plate 31 at the bottom of the upper turntable 3. The wave crest of the wave groove pushes the limit rod 54, causing the telescopic rod 51 to extend and stretch the spring 52. The spring 52 resets and contracts at the trough, driving the cutter 53 to retreat, forming a reciprocating sawing motion;

[0066] Step 3: After the cutting is completed, the cut part of the willow branch falls into the inside of the workbench 1 from the discharge port 11 as waste, and is automatically transported to the outside of the workbench 1 by the conveyor belt 8. The remaining willow branch body remains on the top surface of the workbench 1 as a plug-in propagation material. Finally, the staff drives the motor 72 to reverse, and drives the conveying rod 74 to rotate upward through the gear 73 to lift the remaining willow branch raw materials. After the staff removes the remaining willow branches, they can re-bind new willow branch bundles.

[0067] The above shows and describes the basic principles, main features, and advantages of the present invention.

The reciprocating willow branch mobile saw according to claim 1, characterized in that: The bidirectional rotation mechanism (6) includes a driving member (61) fixedly arranged inside the workbench (1), the output end of the driving member (61) is transmission-connected to a first bevel gear (62), the outside of the first bevel gear (62) is meshed with an auxiliary bevel gear (63), the outside of the auxiliary bevel gear (63) is meshed with a second bevel gear (64), the top of the first bevel gear (62) is fixedly connected to a connecting rod (621), the top of the second bevel gear (64) is fixedly connected to a connecting cylinder (641), the top of the connecting cylinder (641) is fixedly connected to the bottom surface of the lower turntable (2), the top of the connecting rod (621) passes through the inside of the second bevel gear (64) and the connecting cylinder (641), and is fixedly connected to the bottom surface of the upper turntable (3).

8. The reciprocating willow branch mobile saw according to claim 7, characterized in that: At least two discharge ports (11) are provided through the top surface of the workbench (1), and at least two conveyor belts (8) are provided inside the workbench (1). The two discharge ports (11) and the two conveyor belts (8) are both provided at a position where the abutment frame (42) and the cutter (53) overlap when viewed from above during the rotation process.

9. The reciprocating willow branch mobile saw according to claim 8, characterized in that: A willow branch transport assembly (7) is provided on the top surface of the workbench (1), and the willow branch transport assembly (7) comprises a fixedly connected mounting plate (71), a side of the mounting plate (71) away from the lower turntable (2) being fixedly connected to a drive motor (72), a side of the mounting plate (71) away from the lower turntable (2) being rotatably connected to two mutually meshing gears (73), and a side of the mounting plate (71) close to the lower turntable (2) being rotatably connected to two transport rods (74).

10. A method for using a reciprocating willow branch mobile saw, characterized in that: The reciprocating willow branch mobile sawing machine according to any one of claims 1 to 9 comprises the following steps: S1. First, the staff gathers the willow branches to be cut into a bundle and fixes the bundle of willow branches through two conveying rods (74). Then, the driving motor (72) is started to drive the two meshing gears (73) to drive the conveying rods (74) to rotate in the forward direction, and the bottom end of the bundle of willow branches is conveyed to the discharge port (11). It is ensured that both ends of the willow branches are limited to avoid shaking during cutting. S2. Afterwards, the staff starts the driving member (61) of the bidirectional rotating mechanism (6), and drives the lower turntable (2) and the upper turntable (3) to rotate synchronously in opposite directions through the meshing transmission of the first bevel gear (62), the auxiliary bevel gear (63) and the second bevel gear (64). During this process, the abutment frame (42) of the abutment assembly (4) applies opposing abutment forces to the upper and lower sides of the willow branch cutting part to fix the willow branch. The cutter (53) of the cutting assembly (5) moves synchronously in opposite directions, forming a bidirectional torsional shear force with the abutment force, concentrating internal stress to reduce fiber tearing. During the rotation of the turntable, the limit rod (54) contacts the wave groove limit plate (31) at the bottom of the upper turntable (3). The wave crest of the wave groove pushes the limit rod (54), causing the telescopic rod (51) to extend and stretch the spring (52). The spring (52) at the wave trough is reset and contracted, driving the cutter (53) to retreat, forming a reciprocating sawing motion. S3. After the cutting is completed, the cut parts of the willow branches fall into the inside of the workbench (1) from the discharge port (11) as waste materials and are automatically transported to the outside of the workbench (1) by the conveyor belt (8). The remaining willow branches remain on the top surface of the workbench (1) and serve as the raw materials for the propagation of the inserted rods. Finally, the staff drives the motor (72) to reverse and drives the conveying rod (74) to rotate upward through the gear (73) to lift the remaining willow branches. After the staff removes the remaining willow branches, they can re-bind new willow branches.
