[0048] The technical scheme of the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the following embodiments are only exemplary descriptions and explanations of the present invention and should not be construed as limiting the scope of protection of the present invention. All technologies implemented based on the above content of the present invention are included in the scope that the present invention is intended to protect.

[0049] This embodiment provides a rubber tapping host machine, which can be used for harvesting natural rubber.

[0050] See also Figure 1-Figure 3 In some embodiments, the rubber tapping machine mainly includes: a driving component 10, a walking driving assembly 20, a cutter head driving assembly 30 and a cutter head 40. The main function of the rubber tapping machine is to drive the cutter head 40 to retract and extend and to drive the rubber tapping machine itself to move, that is, it needs to perform walking actions and retracting actions of the cutter head, and a certain time difference is required between the two actions.

[0051] Specifically, a first gear 11 and a second gear 12 are disposed on the output shaft of the driving component 10; the first gear 11 and the second gear 12 are coaxially disposed, and rotate synchronously with the output shaft of the driving component 10. The sizes of the first gear 11 and the second gear 12 can be different, and are specifically selected according to the rotation speed requirements of each functional component. For example, in one embodiment, the diameter of the first gear 11 is greater than the diameter of the second gear 12. The first gear 11 is used to drive the travel drive assembly 20, and the second gear 12 is used to drive the cutter head drive assembly 30.

[0052] Further, see Figure 3 and Figure 4The travel drive assembly 20 includes a third gear 21, a worm 22, a first driven wheel 23 and a second driven wheel 24. The first driven wheel 23 is arranged at the first end of the worm 22, and the second driven wheel 24 is arranged at the second end of the worm 22. The third gear 21 is arranged between the first driven wheel 23 and the second driven wheel 24, and the center hole of the third gear 21 is spirally matched with the worm 22. The first gear 11 is meshed with the third gear 21 and can drive the third gear 21 to move along the axial direction of the worm 22. That is to say, the third gear 21 is meshed with the first gear 11 while also spirally matched with the worm 22. Therefore, as the first gear 11 is driven, the third gear 21 itself rotates circumferentially and moves along the axial direction of the worm 22.

[0053] In this embodiment, the third gear 21 is designed to have at least three working states. In the first state, the third gear 21 moves along the axial direction of the worm 22, that is, it rotates and moves along the axial direction of the worm 22 at the same time; when the third gear 21 moves to a position engaged with the first driven wheel 23, it switches to the second state. In the second state, the third gear 21 engages with the first driven wheel 23 and drives the first driven wheel 23 to rotate synchronously. At this time, the third gear 21 no longer moves along the axial direction of the worm 22, and the third gear 21 rotates synchronously with the worm 22 and the first driven wheel 23. The first driven wheel 23 can be used to connect the walking module on the rubber tapping machine, thereby driving the entire rubber tapping machine to walk. When the third gear 21 moves in the opposite direction to the position meshing with the second driven wheel 24, it switches to the third state. In the third state, the third gear 21 meshes with the second driven wheel 24 and drives the second driven wheel 24 to rotate synchronously. At this time, the third gear 21 no longer moves along the axial direction of the worm 22. The third gear 21 rotates synchronously with the worm 22 and the second driven wheel 24. The second driven wheel 24 can be used to connect the walking module on the rubber tapping machine, thereby driving the entire rubber tapping host to walk; the third gear 21 drives the first driven wheel 23 to rotate in a direction opposite to the direction of rotation of the second driven wheel 24, thereby satisfying that the rubber tapping host can walk forward or backward.

[0054] In the first state, the third gear 21 does not mesh with the first driven wheel 23 or the second driven wheel 24 , so the first driven wheel 23 and the second driven wheel 24 do not rotate.

[0055] The cutter head driving assembly 30 includes a telescopic push rod rack 31 and a cutter holder 32 hinged to the telescopic push rod rack 31. The telescopic push rod rack 31 is engaged with the second gear 12 and moves synchronously with the rotation of the second gear 12. The cutter head 40 is arranged at the end of the cutter holder 32. The second gear 12 drives the telescopic push rod rack 31 to push the cutter holder 32, thereby pushing the cutter head 40 to retract.

[0056] Since the first gear 11 and the second gear 12 rotate synchronously, the third gear 21 driven by the first gear 11 and the telescopic push rod rack 31 driven by the second gear 12 also move synchronously, and the third gear 21 does not drive the first driven wheel 23 and the second driven wheel 24 in the first state, so that the walking action cannot be performed. However, since the telescopic push rod rack 31 always moves with the second gear 12, the telescopic push rod rack 31 performs the action of retracting the knife head in the first state of the third gear 21. When the moving stroke of the telescopic push rod rack 31 reaches the end point, the third gear 21 just engages with the first driven wheel 23 or the second driven wheel 24, thereby performing the walking action.

[0057] The rubber tapping main machine in the above embodiment uses only one driving component 10, and drives the cutter head 40 to extend and retract through the time period of movement on the worm 22 of the third gear 21. After the extension and retraction action of the cutter head 40 is completed, the third gear 21 engages with the first driven wheel 23 or the second driven wheel 24, thereby driving the movement; the overall structural design is simple, the driving effect is stable, and the rubber tapping efficiency of the rubber tapping machine is improved.

[0058] In some embodiments, the first driven wheel 23 and the second driven wheel 24 are both fixedly connected to the worm 22, so that the three rotate synchronously without time interruption; the fixed connection method can be welding, screw connection, clamping, etc. The direction in which the third gear 21 drives the first driven wheel 23 to rotate in the second state is opposite to the direction in which the third gear 21 drives the second driven wheel 24 to rotate in the third state, so that the rubber tapping host can move forward or backward.

[0059] In some embodiments, the working process of the rubber tapping main machine is as follows: the driving component 10 drives the first gear 11 and the second gear 12 to rotate synchronously in the forward direction, wherein the first gear 11 is meshed with the third gear 21, and drives the third gear 21 to move along the axial direction of the worm 22. During this process, the second gear 12 drives the telescopic push rod rack 31 to move in a straight line, so that the telescopic push rod rack 31 drives the tool holder 32, and then pushes the cutter head 40 to extend. When the cutter head 40 is extended, the third gear 21 just moves to a state of meshing with the first driven wheel 23, thereby driving the first driven wheel 23 to rotate synchronously, thereby driving the entire rubber tapping main machine to move, and the cutter head 40 performs rubber tapping operations during the movement. After the cutter head 40 is extended, the second gear 12 is no longer meshed with the telescopic push rod rack 31, and therefore no longer drives the telescopic push rod rack 31 to move, so that the cutter head 40 remains in the extended state to perform rubber tapping operations. Industry; after moving one end distance, the rubber tapping main machine moves to the end of the stroke, and the driving component 10 drives the first gear 11 and the second gear 12 to rotate synchronously in the opposite direction. At this time, the second gear 12 is further meshed with the telescopic push rod rack 31, and drives the telescopic push rod rack 31 to move in the opposite direction, and then the cutter head 40 is retracted through the tool holder 32 to complete the knife retracting action. During this process, the third gear 21 moves along the axial direction of the worm 22 from the position engaged with the first driven wheel 23. Before moving to engage with the second driven wheel 24, the first driven wheel 23 and the second driven wheel 24 do not rotate, so that the entire rubber tapping main machine also walks. During this period, the telescopic push rod rack 31 and the tool holder 32 are driving the cutter head 40 to retract the knife. When the third gear 21 moves to engage with the second driven wheel 24, the knife retracting action is completed, and the second driven wheel 24 also starts to rotate, thereby driving the entire rubber tapping main machine to walk. It can be seen that the rubber tapping machine does not move during the process of extending and retracting the knife. After the extending and retracting actions are completed, the rubber tapping machine starts to move, thereby avoiding damage to the knife head 40 when extending and retracting the knife.

[0060] See also Figure 3 and Figure 4 Both ends of the third gear 21 have grooves, each groove is provided with a pushing portion 211, the pushing portion 211 can be a rib formed in the groove, the first driven wheel 23 is provided with a first meshing tooth 231 on the side close to the third gear 21, and the second driven wheel 24 is provided with a second meshing tooth 241 on the side close to the third gear 21; the pushing portion 211 pushes the first driven wheel 23 to rotate by meshing with the first meshing tooth 231, and the pushing portion 211 pushes the second driven wheel 24 to rotate by meshing with the second meshing tooth 241.

[0061] Specifically, the pushing portion 211 has a pushing surface and an inclined sliding surface, the first meshing tooth 231 has a pushed surface and an inclined sliding surface, and the second meshing tooth 241 also has a pushed surface and an inclined sliding surface. The pushing portion 211 pushes the pushed surface of the first meshing tooth 231 or the second meshing tooth 241 through the pushing surface, so that the first driven wheel 23 or the second driven wheel 24 rotates. When the third gear 21 reverses, the pushing surface disengages from the pushed surface.

[0062] See also Figure 5-Figure 8 The telescopic push rod rack 31 includes a push rod body 311, a guide rod 312, an elastic member 313 and a rack 314. The push rod body 311 has a first mounting groove 301. The two ends of the guide rod 312 are respectively arranged at the two ends of the first mounting groove 301. The elastic member 313 and the rack 314 are both sleeved on the guide rod 312, and the elastic member 313 is located at the end of the rack 314. The elastic member 313 elastically squeezes the rack 314, and the rack 314 is engaged with the second gear 12.

[0063] The elastic member 313 can be a spring sleeved on the guide rod 312, and its function is to make the rack 314 have a tendency to move toward one end, that is, the rack 314 can move a certain distance along the length direction of the guide rod 312 in the first mounting groove 301, and its function is to change the meshing state with the second gear 12. When the telescopic push rod rack 31 moves as a whole to the end of the stroke, the second gear 12 and the rack 314 are no longer meshed. When the second gear 12 is rotated in the reverse direction, the rack 314 can easily continue to mesh with the second gear 12 under the elastic action of the elastic member 313 and move in the reverse direction.

[0064] In some embodiments, the cutter head drive assembly 30 also includes a sector gear 33, a limiting component 34 and a stop component 35. The sector gear 33 is arranged at the end of the rack 314, and a pin shaft hole 331 is opened on the sector gear 33; the rotating shaft of the sector gear 33 is connected to the push rod body 311, and the sector gear 33 can rotate around the rotating shaft.

[0065] A second mounting groove 302 is provided on the push rod body 311, and a limiting component 34 is arranged in the second mounting groove 302, and a pin shaft 341 on the limiting component 34 extends into the pin shaft hole 331, and the sector gear 33 can push the pin shaft 341 through the pin shaft hole 331, so that the limiting component 34 is partially extended from the second mounting groove 302. After the limiting component 34 is partially extended from the second mounting groove 302, it can form a limit with the stop component 35, thereby preventing the entire telescopic push rod rack 31 from continuing to move; specifically, the stop component 35 is arranged on one side of the push rod body 311, and is used to stop the limiting component 34 when the limiting component 34 is partially extended from the second mounting groove 302.

[0066] See also Figure 7The limiting component 34 is located inside the second installation groove 302 and cannot form a limit with the stop component 35. Figure 8 The limiting component 34 extends out from the second installation groove 302 so as to form a limit with the stopping component 35 .

[0067] A sector gear 33 may be provided on both sides of the push rod body 311 , and pin shafts 341 extend from both ends of the limiting component 34 . The two sector gears 33 push the pin shaft 341 at the same time, so that the limiting component 34 slides out from the second installation slot 302 .

[0068] One end opening of the second mounting groove 302 may be located at the bottom of the first mounting groove 301 , and the other end opening of the second mounting groove 302 is located at a side opposite to the first mounting groove 301 .

[0069] In some embodiments, a first torsion spring 332 is disposed on the rotating shaft of the sector gear 33, and the driving component 10 is a motor; the first torsion spring 332 can reset the sector gear 33, and after the second gear 12 is engaged with the sector gear 33, the sector gear 33 can be driven to rotate, thereby pushing the pin 341 through the pin hole 331, and then pushing the limiting component 34 to slide out of the second mounting groove 302. Since the number of teeth of the sector gear 33 is limited, the sector gear 33 will no longer rotate after rotating a certain angle, and can only rotate in the opposite direction with the second gear 12 when the second gear 12 is reversed. The first torsion spring 332 can make it easy for the sector gear 33 to mesh with the second gear 12 when the second gear 12 is reversed.

[0070] In some embodiments, when the second gear 12 drives the telescopic push rod rack 31 to move the entire stroke, the first gear 11 drives the third gear 21 to move from the position engaged with the first driven wheel 23 to the position engaged with the second driven wheel 24 or from the position engaged with the second driven wheel 24 to the position engaged with the first driven wheel 23. In other words, when the knife is retracted or extended, the third gear 21 does not drive the first driven wheel 23 and the second driven wheel 24 to rotate, and the entire rubber tapping main machine does not move. When the rubber tapping main machine moves, the cutter head 40 remains in an extended state or a retracted state, thereby preventing the cutter head 40 from being damaged.

[0071] See also Fig.12 The cutter head driving assembly 30 further includes a push rod mounting seat 36, which is disposed on the lower housing 51 of the rubber tapping main machine. The push rod mounting seat 36 has two guide posts 361. The push rod body 311 is provided with two long holes 3111, and the two guide posts 361 are respectively slidably matched in the two long holes 3111. Thus, the push rod body 311 can reciprocate along the relative directions of the two guide posts 361.

[0072] In some embodiments, the rubber tapping main machine further comprises an upper housing 50, which is buckled with a lower housing 51 to form a receiving chamber, enclosing most of the structure of the rubber tapping main machine, and the driving component 10 is located outside the receiving chamber. The upper housing 50 and the lower housing 51 can provide a mounting base for the driving component 10 and each gear.

[0073] See also Figure 9-11 The tool holder 32 includes a first bracket 321, a second bracket 322 and a second torsion spring 323. The first bracket 321 is hinged to the push rod body 311. Specifically, a waist-shaped hole is provided at the end of the push rod body 311, and the end of the first bracket 321 is inserted into the waist-shaped hole through a pin shaft, so that the first bracket 321 and the push rod body 311 are hinged.

[0074] The second bracket 322 is hinged to the first bracket 321 . The second torsion spring 323 is disposed at the hinge position between the first bracket 321 and the second bracket 322 to play a resetting role. The cutter head 40 is disposed on the second bracket 322 .

[0075] Furthermore, the tool holder 32 further includes an adjusting screw 324 disposed on the second bracket 322, and the adjusting screw 324 is connected to the first bracket 321. The adjusting screw 324 can be used to adjust the relative angle between the first bracket 321 and the second bracket 322, thereby adjusting the cutting depth of the tool head 40.

[0076] In summary, the rubber tapping machine in the above embodiment innovatively proposes to use a single drive motor to tap rubber, and power decoupling to control the rise and fall of the cutter head and the walking mechanism; the motor drives the walking mechanism and controls the timing of the cutter head, which are perfectly divided in the power decoupling process. The walking, control of the cutter head linkage and the timing are all in line with the control of rubber tapping requirements. The complex power mechanism of the rubber tapping machine motor and the frequent jamming phenomenon are avoided, and the transmission efficiency is further improved. The artificial natural rubber tapping action is completely simulated, and the mechanical reproduction of the unique action of natural rubber tree tapping is achieved at one time.

[0077] This embodiment further provides a rubber tapping machine, see Fig.13 In some embodiments, the rubber tapping machine mainly includes: two flexible tracks 1, a first walking module 2 arranged on one of the flexible tracks 1, a second walking module 3 arranged on the other flexible track 1, and a rubber tapping host 4, and the rubber tapping host 4 can be the rubber tapping host of any of the above embodiments;

[0078] The rubber tapping main machine 4 is respectively connected to the first walking module 2 and the second walking module 3 through the walking power transmission shaft 5.
