[0009] Furthermore, an adjusting bolt is threadedly connected to the second knife seat, and the adjusting bolt abuts against the adjustable spring through a spring seat, and the adjusting bolt is used to adjust the tension of the adjustable spring.

[0010] Furthermore, first limit baffles are provided on both sides of the first tool holder, and a second limit baffle is provided on the second tool holder. The first limit baffle cooperates with the second limit baffle to limit the first tool holder in the second tool holder.

[0018] The technical solution of the present invention will be described clearly and completely below 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 creative work are within the scope of protection of the present invention.

[0019] like Figure 1 The schematic structural diagram of a rubber tapping device shown in the figure comprises a first knife seat 1, a worm gear 2, a rubber tapping knife rod 3, a rubber tapping blade 4, a worm 5, a motor 6 and an elastic scraper 7.

[0020] Specifically, a worm gear 2 is rotatably provided on the first knife seat 1, and the above-mentioned rubber tapping knife rod 3 is fixedly connected to the shaft of the worm gear 2. The worm gear 2 is used to drive the rubber tapping knife rod 3 to rotate. A rubber tapping blade 4 is provided on the rubber tapping knife rod 3, and the extension length and installation angle of the rubber tapping blade 4 relative to the rubber tapping knife rod 3 can be adjusted. Specifically, the rubber tapping blade 4 can be extended relative to the rubber tapping knife rod 3 along the length direction of the blade, and the rubber tapping blade 4 can also be installed at an angle relative to the rubber tapping knife rod 3. That is, before the rubber tapping blade 4 is fastened and connected to the rubber tapping knife rod 3, the extension length and installation angle of the rubber tapping blade 4 can be adjusted to meet the needs of rubber tapping operations.

[0021] A worm 5 is arranged on the side of the first knife seat 1, and one end of the worm 5 is connected to a motor 6, which provides a driving force for the worm 5 to rotate. The worm 5 is meshed with the worm wheel 2, and the worm 5 and the worm wheel 2 are driven to drive the rubber tapping blade 4 on the rubber tapping knife rod 3 connected to the worm wheel 2 to rotate at the moment of cutting in and out. The operation process of cutting in - cutting (cutting) - cutting out - resetting is completed under the control of the control board in the main control box 16 of the rubber tapping device through an electronic sensing device.

[0022] In addition, in this embodiment, an elastic scraper 7 is also provided on the first blade holder 1. When the tapping blade 4 completes a tapping operation, the elastic scraper 7 can be used to clean the bark or other materials remaining on the tapping blade 4 after the blade is removed to avoid affecting the subsequent tapping operation.

[0023] In this embodiment, a limiting wheel 8 is also provided, and the limiting wheel 8 is rotatably connected to the rubber tapping knife rod 3 fixed on the shaft of the worm gear 2. The limiting wheel 8 is provided to be able to press against the rubber tree 14 during the rubber tapping operation to limit the cutting depth of the rubber tapping blade 4 and ensure that the rubber tapping depth at the rubber tapping location remains consistent.

[0024] In this embodiment, a second knife seat 10 is provided outside the first knife seat 1 , and an adjustable spring 11 is provided between the second knife seat 10 and the first knife seat 1 . The adjustable spring 11 is used to suspend and support the first knife seat 1 in the second knife seat 10 .

[0025] Specifically, an adjusting bolt 12 is threadedly connected on the second knife seat 10, and the adjusting bolt 12 abuts against the above-mentioned adjustable spring 11 through a spring seat 13. By adjusting the tension of the adjusting bolt 12, the abutment length of the adjusting bolt to the spring seat 13 is adjusted, and then the tension of the adjustable spring 11 is adjusted. During the rubber tapping operation, under the action of the limiting wheel 8, the rubber tapping blade 4 can realize contour cutting according to the changes in the concave and convex shapes of the rubber tree 14 to meet the actual rubber tapping needs. The size of the tension needs to be reasonably adjusted according to actual needs.

[0026] In addition, in this embodiment, first limit baffles 101 are provided on both sides of the first tool holder 1, and second limit baffles 1001 are provided on the second tool holder 10. The first limit baffles 101 and the second limit baffles 1001 cooperate to limit the first tool holder 1 in the second tool holder 10 to prevent the first tool holder 1 from falling out of the second tool holder 10.

[0027] In this embodiment, for the above-mentioned rubber tapping blade 4, refer to Figure 2 The rubber tapping blade 4 includes a main blade 401 , an auxiliary blade 402 connected to one end of the main blade 401 , and a handle 403 connected to the other end of the main blade 401 .

[0028] In this embodiment, a main blade 4010 is provided on one side end surface of the main blade 401, and a secondary blade 4020 is provided on the same side end surface of the secondary blade 402. The main blade 4010 and the secondary blade 4020 have the same cutting edge direction. Figure 2 , Figure 3 and Figure 4 When the main blade 401 and the auxiliary blade 402 are integrally bent, a bending line is formed. The bending line is respectively perpendicular to the aforementioned main blade 4010 and the auxiliary blade 4020. Simultaneously, in this embodiment, the angle between the main blade 401 and the auxiliary blade 402 is also controlled to be 75-80 degrees.

[0029] Thus, by means of the vertical setting of the bending line relative to the primary and secondary cutting edges, and the 75-80° included angle setting of the primary and secondary blades, when the rubber tapping blade 4 is performing the rubber tapping operation, a small portion (i.e., a portion of the rubber tapping blade 4 extending toward the secondary blade 402 from the outer side of the corner where the primary blade 401 and the secondary blade 402 are connected is Figure 5 A certain distance is maintained between the rubber tree 14 located outside the rubber tapping blade 4 to avoid the outside of the rubber tapping blade 4 pressing the wood on the rubber tree 14, affecting the rubber juice discharge, and improving the rubber discharge rate and the smoothness of rubber tapping.

[0030] Figure 4 In the embodiment, when the main blade 401 and the auxiliary blade 402 are unfolded, the main blade edge 4010 and the auxiliary blade edge 4020 are located in a straight line, or they may not be located in a straight line.

[0031] See also Figure 3 and Figure 5 The main blade 4010 is formed with a first inclination angle 4011 in the length direction relative to the main blade 401 , and the secondary blade 4020 is formed with a second inclination angle 4021 in the length direction relative to the secondary blade 402 .

[0032] The first inclination angle 4011 and the second inclination angle 4021 can be the same or different, and can be reasonably adjusted according to the actual needs of rubber tapping. In this embodiment, the angle size of the first inclination angle 4011 and the second inclination angle 4021 is controlled to be about 15°.

[0033] The design of the inclination angle enables the main blade 4010 and the auxiliary blade 4020 to have a sliding cutting function during operation, so that they can cut into the bark 15 more effortlessly, thereby improving the flatness of the tapping wound surface.

[0034] Through the reasonable inclination angle design, the sharpness of the blade during operation is improved, which can avoid excessive wear of the blade, increase the service life of the rubber tapping knife, and reduce the frequency of tool replacement.

[0035] In this embodiment, refer to Figure 2 The intersection of the main blade 4010 and the secondary blade 4020 is also formed with a sharp blade tip 9. The sharp blade tip 9 helps to cut into the bark 15 of the rubber tree 14 more easily, reduces the resistance of cutting, and improves the efficiency of rubber tapping.

[0036] In addition, in this embodiment, a main front surface is provided on the main blade 4010 and the secondary blade 4020. The main front surface is located on the outer side of the rubber tapping blade 4. According to the process requirements of the rubber tapping operation, the sharpness of the main front surface is preferably about 30°.

[0037] In this embodiment, an electronic sensing device is also provided, and the electronic sensing device can be provided as a magnetic sensing device or a photoelectric sensing device.

[0038] See also Figure 8 When the electronic induction device is set as a magnetic induction device, a hole can be opened on the rubber tapping knife rod 3, and a permanent magnet 18 is installed in the hole. The permanent magnet 18 is set corresponding to the Hall element I 18E, Hall element II 18F and Hall element III 18G on the first knife seat 1. There are three Hall elements in this embodiment, one is set at the initial position of the rubber tapping blade 4 (i.e. 18F in the figure), the second is set at the point where the rubber tapping blade 4 is in vertical contact with the rubber tree 14 before tapping (i.e. 18E in the figure), and the third is 18G in the figure, which is used for the installation and adjustment of the rubber tapping blade 4.

[0039] Hall element I18E and Hall element III18G are symmetrically arranged relative to the center of the worm wheel 2. In order to facilitate the installation of the rubber tapping blade 4 and ensure that the rubber tapping blade 4 is perpendicular to the tree trunk before the rubber tapping operation, a Hall element III18G is arranged, and the blade is installed at the installation point of the Hall element III18G, and the extension length and installation angle of the rubber tapping blade 4 relative to the rubber tapping knife rod 3 can also be adjusted to ensure that the rubber tapping blade 4 can be accurately debugged to the required state during the trial cutting operation. It should be noted that the Hall element III18G is only used during the installation, debugging and maintenance of the rubber tapping blade 4, and does not work during the specific rubber tapping operation.

[0040] When the rubber tapping machine starts tapping operation after the rubber tapping system issues an instruction, the main control box 16 in the rubber tapping device starts the main motor 17, and the vertical guide rail 22 and the screw rod 23 on the main machine move horizontally counterclockwise along the upper and lower parallel guide rails 20 and lower guide rails 21 that embrace the rubber tree 14. At the same time, the rubber tapping device moves downward under the action of the vertical guide rail 22 and the screw rod 23 until the rubber tapping device is reset to the starting tapping position, and the main motor 17 stops.

[0041] Then, the motor 6 is started, and the main motor 17 is started at the same time. The main motor 17 drives the vertical guide rail 22 and the screw rod 23 to move horizontally clockwise along the upper and lower parallel guide rails 20 and lower guide rails 21 that surround the rubber tree 14, and the rubber tapping device moves upward under the action of the vertical guide rail 22 and the screw rod 23. The motor 6 synchronously drives the worm 5, which in turn drives the worm gear 2, and the worm gear 2 drives the rubber tapping blade 4 to rotate.

[0042] It should be noted that, in this embodiment, when the rubber tapping device is reset to the starting rubber tapping position and the rubber tapping operation begins, the motor 6 and the main motor 17 are started synchronously, because the cutting edge of the rubber tapping blade 4 needs to be consistent with the rotation direction of the rubber tapping blade 4 to avoid the rubber tapping blade 4 from breaking during the rubber tapping operation. When the two motors are started at the same time, the rubber tapping blade 4 moves obliquely upward, so that the moving direction of the rubber tapping blade 4 can be consistent with its cutting edge, thereby avoiding the occurrence of blade breaking.

[0043] When the rubber tapping blade 4 rotates and cuts into the rubber tree 14 until it is perpendicular to the rubber tree 14, the permanent magnet 18 on the rubber tapping blade rod 3 cooperates with the Hall element I18E located at a perpendicular position. After the Hall element I18E senses the rubber tapping blade 4, it sends a sensing signal to the main control box 16. At this time, the main control box 16 immediately turns off the motor 6, and the main motor 17 continues to work, driving the knife seat part to move obliquely around the trunk, driving the rubber tapping blade 4 to perform rubber tapping on the rubber tree 14. The specific tapping length and tapping depth can be reasonably adjusted according to actual needs.

[0044] When the rubber tapping blade 4 completes a rubber tapping operation of a predetermined distance, the main motor 17 of the rubber tapping machine stops working and the motor 6 is started again. The motor 6 drives the worm 5, the worm 5 drives the worm wheel 2, and the worm wheel 2 drives the rubber tapping blade 4 to continue to rotate counterclockwise in the direction away from the rubber tree 14 to complete the knife-out action until it rotates to the initial position of the rubber tapping blade 4. When the Hall element II 18F at the initial position senses the permanent magnet 18 on the rubber tapping knife rod 3, it will send an induction signal to the main control box 16, and the main control box 16 will immediately turn off the power supply of the motor 6, and the motor 6 will stop working.

[0045] When a second rubber tapping operation is required, the main control box 16 will send a start command to the main motor 17, and the main motor 17 will drive the knife holder part to move to the initial operating position to perform the rubber tapping operation again.

[0046] And by Figure 8 and Fig. 9 It can be seen that when the rubber tapping blade 4 rotates from the initial position to a position perpendicular to the rubber tree 14, the knife seat part translates clockwise on the upper guide rail 20 and the lower guide rail 21 arranged in parallel, and the vertical guide rail 22 superimposes the knife head of the rubber tapping blade 4 and rotates counterclockwise to form a track with a certain arc, that is, the H part in the figure. The H track wound on the cut bark 15 can also produce a certain amount of rubber juice, thereby correspondingly increasing the rubber output.

[0047] During the specific operation, the rubber tapping machine equipped with the rubber tapping device is installed on the rubber tree 14 to be tapped, the rubber tapping machine is started, and when the main machine knife seat 19 moves to the starting point of tapping, the motor 6 is started, and the worm 5 is driven by the motor 6 to rotate, and the worm 5 is connected to the worm gear 2, thereby driving the rubber tapping blade 4 connected to the worm gear 2 to rotate.

[0048] In the prior art, before the rubber tapping operation, it is necessary to cut a knife groove in the vertical direction in advance on the tree trunk. The width of the knife groove is generally large, so that after the bark is removed, the rubber tapping knife can approach the wood in the bark 15 to tap the rubber, so that it is easy to cut the rubber when the bark is cut obliquely in the subsequent operation. However, in this operation, the rubber at the knife groove where the bark is cut will solidify in a short time, and will no longer be cut each time the rubber is tapped, thereby affecting the rubber tapping yield to a certain extent. In the present embodiment, since it is easier to cut the rubber tapping blade 4 in the vertical direction, it is not necessary to cut a groove in the vertical direction on the tree trunk in advance, which is conducive to improving the rubber tapping yield.

[0049] When the rubber tapping blade 4 is pulled out, the bark 15 is smoothly cut off under the power of rotation, thereby avoiding the problem of the blade being stuck. At the same time, the cut wound is also conducive to increasing the yield. At the same time, during the reset process of the rubber tapping blade 4, the preset elastic scraper 7 can remove the bark and rubber juice adhering to the blade, greatly reducing the working intensity of the rubber worker and ensuring the smooth progress of the mechanical rubber tapping operation.

[0050] With further transmission of the worm wheel 2 and the worm 5, the tapping blade 4 will continue to rotate in the direction away from the rubber tree 14 (i.e., the tapping direction) after the rubber tapping blade 4 is cut out. When the rubber tapping blade 4 rotates to approach the aforementioned Hall element II 18F, the Hall element II 18F senses the permanent magnet 18, the main control box 16 turns off the motor 6, and the rubber tapping blade 4 is reset to the initial working position.

[0051] In summary, the rubber tapping device provided in the present invention integrates the motor 6, the worm 5 and the worm gear 2, thereby providing the rubber tapping blade 4 with the power of rotating in and out, and synchronously forms a first inclination angle 4011 on the length direction of the main blade 4010 relative to the main blade 401, and forms a second inclination angle 4021 on the length direction of the secondary blade 4020 relative to the secondary blade 402, so that the rubber tapping blade 4 performs a sliding cutting motion when cutting in and out on the rubber tree 14, reducing the resistance to tapping while being able to cut the bark relatively effortlessly, thereby ensuring the smoothness of the tapping operation.

[0052] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
