[0001] The present application claims priority from Chinese Patent Application No. 202410646676.1 filed on May 23, 2024, the contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of agricultural machinery, in particular to a rubber tapping device. BACKGROUND

[0003] Natural rubber, as an important industrial raw material, is widely used in various fields such as industry, national defense, transportation, aerospace, medicine and health, and daily life due to its strong elasticity, good insulation, plasticity, water and air resistance, tensile strength and wear resistance. Natural rubber is mainly obtained by cutting the bark of rubber trees. Rubber tapping is a work that requires high technical operation ability. Good rubber tapping technology not only increases the yield of rubber trees during the production cycle, but also avoids damage to the trunk of the rubber tree by the rubber tapping knife, thereby prolonging the life of the rubber tree.

[0004] At present, rubber tapping is mainly carried out manually. With the aging of experienced rubber tapping workers and the large increase in labor costs, major rubber plantations are facing problems such as labor shortage, excessive labor costs, high labor intensity, and low work efficiency. Therefore, promoting the mechanization of rubber tapping has become the main trend of the development of rubber tapping technology. Existing mechanized rubber tapping devices generally move on a guide rail through a vehicle-mounted frame mechanism to drive the knife holder mechanism to tap rubber trees. However, this rubber tapping equipment is troublesome to adjust the starting position of the knife holder mechanism when moving to the next rubber tree for tapping work, which hinders the work efficiency of the rubber tapping device and brings certain installation difficulty to the operator. SUMMARY

The guide rail of the rubber tapping device includes a limiting pre-tightening member, which has a limiting effect on the vehicle-mounted frame mechanism. When the vehicle-mounted frame mechanism moves along the guide rail, the first transmission part of the vehicle-mounted frame mechanism always maintains contact with the end teeth of the guide rail. When adjusting the starting position of the knife holder mechanism through the lead screw, the limiting pre-tightening member limits the vehicle-mounted frame mechanism, ensuring the stability of the rubber tapping device. The rubber tapping device has small installation difficulty, simplifies the installation steps, greatly saves labor costs, and effectively improves work efficiency.

DETAILED DESCRIPTION

[0049] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. In the following description, a large number of specific details are set forth in order to facilitate a full understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0050] The technical solutions of some embodiments of the present application are described below with reference to Figs. 1-14.

[0051] The embodiments of the present application provide a rubber tapping device 10, as shown in Figs. 1-3, which comprises a guide rail 100 arranged around a rubber tree, a vehicle-mounted frame mechanism 200 comprising a first driving member 210, a first transmission part 220 and a lead screw 230, and a cutter frame mechanism 300 connected with the vehicle-mounted frame mechanism 200 through the lead screw 230, wherein the first driving member 210, the first transmission part 220 and the lead screw 230 cooperate to drive the cutter frame mechanism 300 to move relative to the rubber tree through the vehicle-mounted frame mechanism 200, and the guide rail 100 is provided with a limiting pre-tightening member 110 for limiting the vehicle-mounted frame mechanism 200.

[0052] The vehicle-mounted frame mechanism 200 of the rubber tapping device 10 comprises the first driving member 210, the first transmission part 220 and the lead screw 230, the first driving member 210 cooperates with the first transmission part 220 to drive the vehicle-mounted frame mechanism 200 to move along the guide rail 100 on the surface of the rubber tree, and the first transmission part 220, the guide rail 100 and the lead screw 230 cooperate to drive the cutter frame mechanism 300 to move relative to the rubber tree and perform rubber tapping work. The guide rail 100 comprises the limiting pre-tightening member 110, which has a limiting effect on the vehicle-mounted frame mechanism 200, so that the first transmission part 220 of the vehicle-mounted frame mechanism 200 always keeps in contact with the terminal tooth 120 of the guide rail 100 when the vehicle-mounted frame mechanism 200 moves along the guide rail 100, thereby limiting the vehicle-mounted frame mechanism 200 through the limiting pre-tightening member 110 when adjusting the initial position of the cutter frame mechanism 300 through the lead screw 230, and ensuring the stability of the operation of the rubber tapping device 10. The rubber tapping device 10 has low installation difficulty and simplifies the installation steps.

[0053] For example, as shown in Fig. 2, the first transmission part 220 is a transmission assembly between the first driving member 210 and the lead screw 230.

[0054] In one embodiment of the present application, as shown in Figs. 3-6, the guide rail 100 comprises a guide rail body 100a, and the limiting pre-tightening member 110 comprises a limiting member body 110a connected to the guide rail body 100a.

[0055] For example, the guide rail 100 comprises the tooth 120.

[0056] For example, the limiting member body 110a is made of a material that can rebound after compression, including at least one of sponge and rubber.

[0057] For example, the limiting member body 110a has a shape that can rebound after compression, including a wave-shaped elastic member.

[0058] The limiting member body 110a of the rubber tapping device 10 is connected with the guide rail body 100a, when the vehicle-mounted frame mechanism 200 contacts with the limiting member body 110a, the limiting member body 110a exerts a reverse force on the vehicle-mounted frame mechanism 200, on the one hand, preventing the vehicle-mounted frame mechanism 200 from slipping off the guide rail body 100a, on the other hand, when the vehicle-mounted frame mechanism 200 moves reversely along the guide rail body 100a, the reverse force exerted by the limiting member body 110a keeps the first transmission part 220 of the vehicle-mounted frame mechanism 200 always engaged with the gear teeth 120 of the guide rail body 100a, so as to ensure the stability of the vehicle-mounted frame mechanism 200 moving along the guide rail body 100a.

[0059] In one embodiment of the present application, referring to FIG. 3 and FIG. 4, the limiting pre-tightening member 110 further comprises a pre-tightening member 111, the pre-tightening member 111 is connected with the limiting member body 110a, and the pre-tightening member 111 is used to exert a reverse pre-tightening force on the vehicle-mounted frame mechanism 200.

[0060] For example, the pre-tightening member 111 is a spring, and the limiting member body 110a is made of hard material, such as hard plastic or steel.

[0061] When the vehicle-mounted frame mechanism 200 moves along the guide rail body 100a to contact with the pre-tightening member 111, one end of the pre-tightening member 111 exerts a reverse pre-tightening force on the vehicle-mounted frame mechanism 200, further ensuring the stability of the vehicle-mounted frame mechanism 200 moving along the guide rail body 100a, and the other end of the pre-tightening member 111 abuts against the limiting member body 110a, and is supported by the reverse force of the limiting member body 110a.

[0062] In one embodiment of the present application, referring to FIG. 3 and FIG. 4, the limiting member body 110a comprises a fixed part 110a1 and a pre-tightening member fixed part 110a2, the fixed part 110a1 is used to connect the limiting member body 110a with the guide rail body 100a, one end of the pre-tightening member 111 is fixed to the pre-tightening member fixed part 110a2, and the other end of the pre-tightening member 111 is suspended.

[0063] The limiting member body 110a has a space below for accommodating at least part of the pre-tightening member 111, and the pre-tightening member fixed part 110a2 is arranged below the limiting member body 110a.

[0064] For example, the limiting member body 110a is block-shaped above, and the fixed part 110a1 is arranged above the limiting member body 110a.

[0065] The limiting member body 110a is connected with the guide rail body 110a through the fixed part 110a1, and the limiting member body 110a and one end of the pre-tightening member 111 are connected through the pre-tightening member fixed part 110a2, which strengthens the stability of the connection between the limiting member body 110a, the guide rail body 100a and the pre-tightening member 111, and facilitates disassembly.

[0066] The limiting pre-tightening member 110 of the rubber tapping device 10 is connected with the guide rail body 100a, and the stability of the limiting pre-tightening member 110 in the guide rail body 100a is strengthened; the limiting member body 110a is connected with the pre-tightening member 111, and the pre-tightening member 111 applies a reverse pre-tightening force to the vehicle-mounted frame mechanism 200, which prevents the vehicle-mounted frame mechanism 200 from slipping off the guide rail body 100a, and when the vehicle-mounted frame mechanism 200 moves reversely along the guide rail body 100a, the reverse pre-tightening force applied by the pre-tightening member 111 ensures that the first transmission part 220 of the vehicle-mounted frame mechanism 200 is always engaged with the teeth 120 of the guide rail body 100a, thereby ensuring the stability of the movement of the vehicle-mounted frame mechanism 200 along the guide rail body 100a.

[0067] For example, the guide rail body 100a includes a mounting groove, and the upper shape of the limiting member body 110a is matched with the shape of the mounting groove, so as to accommodate at least part of the limiting member body 110a.

[0068] For example, the limiting member body 110a is bolted with the guide rail body 100a.

[0069] For example, the pre-tightening member 111 is bolted with the limiting member body 110a.

[0070] In an embodiment of the present application, referring to FIG. 3 and FIG. 4, the guide rail 100 includes a guide rail body 100a and teeth 120; the guide rail body 100a has a first length d1; the teeth 120 are arranged on the side wall of the guide rail body 100a away from the rubber tree, and are used for the movement of the vehicle-mounted frame mechanism 200 along the guide rail body 100a; the teeth 120 have a second length d2; and the first length d1 is greater than the second length d2.

[0071] The guide rail 100 of the rubber tapping device 10 includes a guide rail body 100a and teeth 120, and the teeth 120 are arranged along the circumference of the guide rail body 100a; the circumference of the teeth 120 is smaller than the circumference of the guide rail body 100a, so that the guide rail body 100a includes a toothed segment and a non-toothed segment, so as to allow the vehicle-mounted frame mechanism 200 to move along the guide rail 100, and the starting position of the tool holder mechanism 300 is adjusted by the lead screw 230 in the non-toothed segment.

[0072] For example, the guide rail 100 is a flexible guide rail; for example, the guide rail 100 is made of ABS, PP-R, PP, PC, ASA, POM, PS or nylon glass fiber material. It can be understood that the material of the guide rail 100 is specifically set to match the shape of the guide rail 100 and the rubber tree, and the adhesion requirement of the guide rail 100 and the vehicle-mounted frame mechanism 200, so that the guide rail 100 can effectively wrap around the rubber tree. Above all, those skilled in the art can select the material disclosed in the present application according to the specific application requirements.

[0073] For example, referring to FIG. 7, the guide rail 100 is provided with a binding hole 130 at both ends, which can be matched with a binding belt to bind the guide rail 100 to the surface of the rubber tree, so that the guide rail 100 is more firmly bound to the rubber tree.

[0074] For example, referring to FIG. 7 and FIG. 8, the periphery of the binding hole 130 is smoothly transitioned. The main effect of the present application that the periphery of the binding hole 130 is smoothly transitioned is that: first, it prevents the sharp edge from scratching and breaking the binding belt; second, the sharp edge of the binding hole 130 is prone to stress concentration and breakage.

[0075] For example, referring to FIG. 9, the guide rail 100 includes a positioning member, and the vehicle-mounted frame mechanism 200 includes a sensor. Specifically, the positioning member is a magnet, and the sensor is a Hall sensor. The magnet cooperates with the Hall sensor to position the vehicle-mounted frame mechanism 200.

[0076] For example, referring to FIG. 9 and FIG. 10, the tooth 120 includes a slot hole 120a, and the slot hole 120a is provided with a support portion 120a1, and the positioning member is placed in the support portion 120a1.

[0077] For example, the slot hole 120a has a circular through hole at the bottom. When the magnet is placed in the support portion, the magnet can be poked through the circular through hole at the bottom to facilitate disassembly of the magnet.

[0078] For example, the shape of the slot hole 120a is similar to the shape of the periphery of the tooth 110. It can be understood that the guide rail 100 is generally an injection molding part, and the surface with irregular thickness is prone to shrinkage during injection molding. To prevent shrinkage, the present application specifically sets the shape of the slot hole 120a to match the shape of the outer edge of the tooth 120, reduces the uneven deformation of the surface of the tooth 120, and makes the tooth 120 mesh with the gear in the first transmission portion 220 more smoothly, and also increases the smoothness and beauty of the guide rail 100.

[0079] For example, referring to FIG. 11, the guide rail 100 includes a limiting portion 140, which is arranged on the side wall of the guide rail 100 close to the rubber tree, and is used to limit the movement of the guide rail 100 on the surface of the rubber tree.

[0080] For example, referring to FIG. 11, the limiting portion 140 includes a first limiting portion 141, which is formed as a protrusion protruding from the guide rail body 100a towards the rubber tree, and a plurality of first limiting portions 141 are distributed circumferentially along the side of the guide rail body 100a close to the rubber tree. The present application specifically sets a plurality of first limiting portions 141 to be distributed circumferentially along the guide rail body 100a, which further increases the friction between the guide rail 100 and the surface of the rubber tree, so that the guide rail 100 can be effectively wrapped around the rubber tree.

[0081] For example, the first limiting part 141 is in the shape of a triangular, square conical, conical or hemispherical protrusion.

[0082] For example, referring to FIG. 11, the limiting part 140 includes two second limiting parts 142, which are protrusions protruding from the ends of the guide rail body 100a toward the rubber tree, and the end of the second limiting part 142 close to the rubber tree is smooth. The two second limiting parts 142 are arranged at the two ends of the guide rail body 100a, and the end of the second limiting part 142 close to the rubber tree is smooth, so that the guide rail 100 moves more smoothly relative to the rubber tree during installation and removal. Especially in the case of binding the guide rail 100 with a binding belt, the guide rail 100 needs to be tightened by the binding belt, and the two ends of the guide rail 100 are subjected to greater resistance from the rubber tree during tightening, which is not conducive to the installation and tightening of the guide rail 100. Therefore, the second limiting part 142 can also play a role in tightening the guide rail 100.

[0083] For example, the second limiting part 142 is in the shape of a trapezoidal, circular ring or hemispherical protrusion.

[0084] For example, referring to FIG. 8, the second limiting part 142 is a roller, and the second limiting part 142 is connected with the guide rail body 100a.

[0085] For example, referring to FIGS. 11 and 12, the protruding length of the first limiting part 141 from the guide rail body 100a toward the rubber tree is a third length d3; the protruding length of the second limiting part 142 from the first end 100b and the second end 100c toward the rubber tree is a fourth length d4; and the fourth length d4 is greater than or equal to the third length d3. The protruding length of the second limiting part 142 from the guide rail body 100a toward the rubber tree is greater than or equal to the protruding length of the first limiting part 141 from the guide rail body 100a toward the rubber tree, and the first limiting part 141 and the second limiting part 142 cooperate when the guide rail 100 is wrapped around the rubber tree, which can effectively prevent the first limiting part 141 and the second limiting part 142 from being embedded in the surface of the rubber tree and causing damage to the rubber tree. In addition, when the guide rail 100 is bound by a binding belt, the two ends of the guide rail 100 may be subjected to a greater binding force, which can cause the first limiting part 141 close to the two ends of the guide rail 100 to be embedded in the rubber tree. By setting the fourth length d4 to be greater than or equal to the third length d3, this situation can be further avoided.

[0086] In one embodiment of the present application, referring to FIGS. 13 and 14, the tool holder mechanism 300 includes a tool head 310, a second transmission part 320, and a second driving member 330; the second driving member 330, the second transmission part 320 and the tool head 310 are connected in sequence, and the second driving member 330 is used to drive the second transmission part 320, so that the second transmission part 320 abuts the tool head 310 to at least the surface of the rubber tree.

[0087] The rubber tapping device 10 specifically taps rubber on the surface of the rubber tree through the cutter holder mechanism 300, the second driving member 330 of the cutter holder mechanism 300 drives the second transmission part 320, so that the cutter head part 310 connected with the second transmission part 320 abuts against at least the surface of the rubber tree, thereby realizing the rubber tapping operation of the cutter holder mechanism 300 on the surface of the rubber tree.

[0088] In an embodiment of the present application, referring to FIGS. 13 and 14, the cutter head part 310 comprises a cutter arm 311, a connecting piece 312, and a cutter holder 313; the cutter arm 311 comprises a first connecting position 311a and a second connecting position 311b; one end of the connecting piece 312 is fixedly connected with the first connecting position 311a, and the other end of the connecting piece 312 is rotationally connected with one end of the cutter holder 313; the other end of the cutter holder 313 is rotationally connected with the second connecting position 311b.

[0089] The cutter holder 313 of the cutter head part 310 is rotationally connected with the cutter arm 311 and the connecting piece 312, respectively, and the cutter holder 313 is driven by the cutter arm 311 and the connecting piece 312, so that the cutter head part 310 abuts against at least the surface of the rubber tree for rubber tapping; and by arranging the cutter holder 313 to be rotationally connected with the cutter arm 311 and the connecting piece 312, respectively, and by arranging the connecting piece 312 to be fixedly connected with the cutter arm 311, the stability of the force received by the cutter head part 310 when abutting against the rubber tree is strengthened.

[0090] For example, referring to FIG. 13, an elastic member is arranged at the other end of the cutter holder 313 and the second connecting position 311b; for example, the elastic member comprises at least one of a tension spring, a push spring, or a torsion spring. The elastic member is used to tighten the cutter head part 310 on the surface of the rubber tree.

[0091] In an embodiment of the present application, the cutter head part 310 comprises a blade 314; the cutter arm 311, the connecting piece 312, and the cutter holder 313 form a first accommodating space 314a; and the first accommodating space 314a is used to accommodate the blade 314.

[0092] For example, the first accommodating space 314a can be "C" shaped or "V" shaped.

[0093] For example, the connecting piece 312 is raised between the two ends thereof to a side away from the first accommodating space 314a. By arranging the shape of the connecting piece 312, the mounting space of the blade 314 is further increased, on the other hand, the passing space of the tree chips cut by the blade 314 is also increased, which effectively avoids the situation that the cutter head part 310 is blocked by the tree chips, further reduces the failure rate, and improves the stability and durability of the machine.

[0094] For example, referring to FIG. 13, the blade 314 is arranged on the cutter holder 313 near the second connecting position 311b. It can be understood that when the rubber tapping machine 10 is performing the rubber tapping operation, a small amount of rubber juice will flow along the blade 314 and immerse into the second connecting position 311b. As the amount of the rubber juice immersed increases, the cutter arm 311 needs to be replaced or the second connecting position 311b needs to be maintained to avoid affecting the rubber tapping operation. Therefore, the connecting piece 312 is arranged in the present application, and the cutter arm 311 can be easily replaced or the second connecting position 311b can be easily maintained by disassembling the connecting piece 312.

[0095] The cutter arm 311, the connecting piece 312 and the cutter holder 313 of the present application surround to form a first accommodating space 314a for accommodating the blade 314. The blade 314 can be installed and replaced in the first accommodating space 314a, and the tree shavings cut by the blade 314 can also be conveniently passed through the first accommodating space 314a.

[0096] In an embodiment of the present application, the second transmission part 320 comprises a sliding block 321 and a gear 322; the cutter arm 311 comprises a third connecting position 311c, and the sliding block 321 is connected with the third connecting position 311c; the sliding block 321 comprises a rack 321a, and the rack 321a is engaged with the gear 322, so as to drive the sliding block 321 to slide through the gear 322, so as to abut the blade 314 against at least a surface of the rubber tree.

[0097] For example, the sliding block 321 is connected with the third connecting position 311c through a spring, and the cutter head part 310 comprises a rotating shaft. When the spring slides with the sliding block 321, the cutter arm 311 rotates around the rotating shaft, so as to abut the blade 314 against at least a surface of the rubber tree.

[0098] When the rubber tapping device 10 is tapping rubber, the cutter holder mechanism 300 is controlled to extend the blade 314, the second driving part 330 drives the gear 322 of the second transmission part 320 to rotate, the gear 322 is engaged with the rack 321a on the sliding block 321, so as to control the sliding block 321 to slide from the first position to the second position, and pull the cutter arm 311, so that the blade 314 abuts against the rubber tree to perform the rubber tapping operation; when the rubber tapping device 10 is not tapping rubber, the cutter holder mechanism 300 is controlled to retract the blade 314, the second driving part 330 drives the gear 322 of the second transmission part 320 to reverse, the gear 322 is engaged with the rack 321a on the sliding block 321, so as to control the sliding block 321 to return from the second position to the first position, and release the cutter arm 311, so that the blade 314 is away from the surface of the rubber tree, to prevent the rubber tapping path from being damaged and to avoid damaging the rubber tree, thereby improving the service life of the rubber tree.

[0099] In one embodiment of the present application, the second transmission part 320 comprises a ratchet wheel 323 arranged on the lead screw 230; the sliding block 321 comprises a pawl 321b matched with the ratchet wheel 323, for driving the ratchet wheel 323 to rotate by the pawl 321b, so as to drive the tool holder mechanism 300 to move along the lead screw 230 by the first target distance.

[0100] When the tool holder mechanism 300 is withdrawn, the sliding block 321 slides from the first position to the second position, the pawl 321b on the sliding block 321 drives the ratchet wheel 323 on the lead screw 230 to rotate, so as to drive the tool holder mechanism 300 to move along the lead screw 230, and the tool holder mechanism 300 moves by the first target distance on the basis of the previous tapping path, so as to perform the next tapping operation, avoid tapping the same position on the rubber tree surface repeatedly, and improve the tapping efficiency.

[0101] The embodiment of the present application also provides a control method of the tapping device 10, for controlling the tapping device 10 of any of the above embodiments, and the control method comprises the following steps:

[0102] S100, acquiring a tapping instruction;

[0103] S200, controlling the tool holder mechanism 300 to withdraw and descend by the first target distance according to the tapping instruction;

[0104] S300, controlling the first driving member 210 to drive the first transmission part 220 matched with the guide rail 100, so as to drive the tool holder mechanism 300 to move along the transverse direction of the rubber tree; the first transmission part 220 drives the lead screw 230 to rotate, so as to drive the tool holder mechanism 300 to move along the longitudinal direction of the rubber tree; the movement along the transverse direction and the movement along the longitudinal direction are matched, so as to drive the tool holder mechanism 300 to perform the tapping operation along the spiral trajectory relative to the rubber tree;

[0105] S400, when the tool holder mechanism 300 completes the movement along the spiral trajectory, controlling the first driving member 210 to stop working, then controlling the tool holder mechanism 300 to perform the tool withdrawal operation, and finally controlling the tool holder mechanism 300 to return along the original path;

[0106] S500, when performing the next tapping operation, repeatedly performing the above steps in a loop until the tapping device 10 completes the tapping operation;

[0107] S600, when the tapping device 10 completes the tapping operation, controlling the tool holder mechanism 300 to perform the reset operation.

[0108] For example, the longitudinal direction is the setting direction of the screw rod 230, and the transverse direction is the vertical direction of the longitudinal direction. The control method of the rubber tapping device 10 according to the rubber tapping instruction sequentially performs the following steps: the cutter holder mechanism 300 is withdrawn and lowered by a first target distance; the vehicle-mounted rack mechanism 200 moves along the guide rail 100 to drive the cutter holder mechanism 300 to move along a spiral trajectory relative to the rubber tree and perform a rubber tapping operation; the cutter holder mechanism 300 is retracted after the rubber tapping operation is completed, and the vehicle-mounted rack mechanism 200 and the cutter holder mechanism 300 return along the original path; the next rubber tapping operation repeats the above steps, and the cycle is repeated until the rubber tapping device 10 completes the rubber tapping operation, and the control method is simple. When the rubber tapping operation is completed, the control method of the present application can also control the cutter holder mechanism 300 to reset and adjust the starting position of the cutter holder mechanism 300. When the rubber tapping operation is completed and the rubber tapping device 10 is transferred to the next rubber tree for rubber tapping operation, the guide rail 100 is only needed to be bound to the circumference of the rubber tree, thereby simplifying the installation steps, reducing the installation difficulty of the rubber tapping device 10, and improving the working efficiency of the rubber tapping device 10.

[0109] In an embodiment of the present application, the guide rail 100 of the rubber tapping device 10 includes a toothed section and a toothless section, and the control method of the cutter holder mechanism 300 to reset specifically includes:

[0110] S610, a reset instruction is obtained;

[0111] S620, according to the reset instruction, the vehicle-mounted rack mechanism 200 is driven by the first driving member 210 to move along the guide rail 100 to the toothless section, and during the movement, the cutter holder mechanism 300 is raised by a second target distance;

[0112] S630, after the vehicle-mounted rack mechanism 200 moves to the toothless section along the guide rail 100, the vehicle-mounted rack mechanism 200 stops rotating along the guide rail 100, the limiting pre-tightening member 110 contacts the vehicle-mounted rack mechanism 200, so that the first transmission part 220 always maintains contact with the terminal tooth 120 arranged on the guide rail 100; the first driving member 210 drives the first transmission part 220 to rotate, and the first transmission part 220 drives the screw rod 230 to rotate, so that the cutter holder mechanism 300 continues to move upward along the screw rod 230;

[0113] S640, when the cutter holder mechanism 300 moves to the target position along the screw rod 230, the first driving member 210 stops and starts to reverse, under the action of the limiting pre-tightening member 110, the first transmission part 220 re-engages with the terminal tooth 120 arranged on the guide rail 100, and the first transmission part 220 cooperates with the guide rail 100 and the screw rod 230 to drive the vehicle-mounted rack mechanism 200 and the cutter holder mechanism 300 to return to the initial position, thereby completing the reset operation.

[0114] According to the reset instruction, the vehicle-mounted tool holder mechanism 200 is controlled to move from the starting position of the guide rail 100 to the toothless gear section, the first driving member 210 drives the first transmission part 220 to rotate in the toothless gear section, the first transmission part 220 drives the lead screw 230 to rotate, so that the tool holder mechanism 300 moves along the lead screw 230 to the target position; then the vehicle-mounted tool holder mechanism 200 also returns to the starting position along the guide rail 100, so that the tool holder mechanism 300 is reset, when the rubber tapping equipment completes the rubber tapping work once and is transferred to the next rubber tree for preparing rubber tapping work, the rubber tapping equipment is convenient to install and transfer. The limiting pre-tightening member 110 is arranged, and a limiting force is applied to the vehicle-mounted tool holder mechanism 200, so that the first transmission part 220 always keeps in contact with the end gear 120 of the guide rail body 100a when the vehicle-mounted tool holder mechanism 200 moves to the toothless gear section, the vehicle-mounted tool holder mechanism 200 is prevented from slipping off the guide rail body 100a, when the vehicle-mounted tool holder mechanism 200 returns to the gear 120 section, the reverse pre-tightening force of the pre-tightening member 111 makes the vehicle-mounted tool holder mechanism 200 engage with the end gear 120 of the guide rail body 100a, and the stability of the rubber tapping device 10 is improved.
