However, the existing rubber tapping devices have the problem of cumbersome gear systems, which leads to the disadvantages of difficult maintenance, high failure rate, and high cost.

[0003] Therefore, how to provide a rubber tapping device with simple structure, low cost and easy maintenance is a problem to be solved urgently. Utility Model Content

[0004] The utility model aims to provide a rubber tapping device, which uses electromagnetic clutch to realize that double-side driving gears separately drive a retractable knife assembly and a cutting track assembly, thereby replacing a complicated gear transmission system.

[0006] The rubber tapping device provided by the utility model is used for automatically tapping rubber liquid from rubber trees. By installing a guide rail on the rubber tree, the entire rubber tapping device is fixed to ensure its stability and correct operating position on the rubber tree. The two structures of the retractable knife assembly and the cutting track assembly work together to complete the rubber tapping operation on the rubber tree, that is, firstly, the knife bar is brought close to the rubber tree by the retractable knife assembly, and then the cutting action is performed by the cutting track assembly. The driving mechanism is movably connected to the guide rail and drives the knife holder mechanism, which includes an electromagnetic clutch mechanism. Through the use of the electromagnetic clutch mechanism, it can be ensured that all functions of the rubber tapping device can be achieved using only one driving mechanism, thereby reducing production costs. The electromagnetic clutch mechanism can separately and accurately control the retractable knife assembly and the cutting track assembly to ensure that the rubber tapping device completes the retractable knife action or the spiral track cutting action, thereby improving the efficiency and accuracy of rubber tapping. Due to the setting of the electromagnetic clutch mechanism, the combined parts of the driving mechanism are simpler and more efficient, and it also has the characteristics of low cost and simple maintenance.

[0012] Under the control of the electromagnetic switch, the electromagnetic connection switching between the transmission part and the first drive gear and the second drive gear is realized in the power-off and power-on states. When the electromagnetic switch is powered off, the transmission part will establish a connection with one of the first drive gear and the second drive gear, and when the electromagnetic switch is powered on, the transmission part will establish a connection with the other gear. This design allows the power transmission path to be flexibly switched under different working conditions, thereby realizing the power control of the rubber tapping device.

[0013] In any of the above technical solutions, the first driving gear is connected to the retractable knife assembly, and the second driving gear is connected to the cutting track assembly.

[0014] By clearly connecting the first drive gear to the knife assembly and the second drive gear to the cutting track assembly, this configuration further optimizes the working efficiency and flexibility of the rubber tapping device.

The first teeth of the first drive gear are used to connect or transmit with the square rod drive gear, and the second teeth of the second drive gear are used to connect or transmit with the screw drive gear.

[0017] In any of the above technical solutions, a notch is provided on one end of the transmission part connected to the double-sided driving gears, and the shape of the notch is adapted to the circumferential shape of the double-sided driving gears.

[0018] By providing a notch at one end of the transmission part connected to the double-sided drive gears, and the shape of the notch matches the circumferential shape of the double-sided drive gears, this design aims to optimize the connection between the transmission part and the drive gears and improve the performance and reliability of the device. The tight connection and precise fit between the transmission part and the gears reduce friction and clearance during movement and improve transmission efficiency.

[0019] In any of the above technical solutions, the knife retracting assembly includes a square rod driving gear and a square rod sleeved with the square rod driving gear, and the driving mechanism includes a locking gear, which cooperates with the square rod driving gear to lock the square rod.

[0020] The square rod driving gear is sleeved on the square rod to drive the other rod, thereby controlling the position and movement trajectory of the knife rod. The locking gear cooperates with the square rod driving gear to lock the other rod. When the knife rod position needs to be fixed, the locking gear can effectively fix the square rod to ensure the accuracy and stability of the knife rod position.

[0022] The locking arcs respectively arranged on the locking gear and the square rod driving gear are used to mesh with each other during operation to form a stable connection to fix the position and movement state of the square rod. The first locking arc meshes with the second locking arc to ensure a tight connection between the locking gear and the square rod driving gear, thereby improving the stability and reliability of the device during operation. Through the meshing between the locking gear and the square rod driving gear, the position and movement trajectory of the cutter bar can be accurately controlled, thereby achieving precise rubber tapping operations.

[0042] like Figure 1As shown, the rubber tapping device provided by the utility model is used for automatically tapping rubber liquid from rubber trees. By installing the guide rail 100 on the rubber tree, the entire rubber tapping device is fixed to ensure its stability and correct operating position on the rubber tree. The two structures of the retractable knife assembly and the cutting track assembly work together to complete the rubber tapping operation on the rubber tree, that is, the knife bar is first brought close to the rubber tree by the retractable knife assembly, and then the spiral cutting action is performed by the cutting track assembly. The driving mechanism 300 is movably connected to the guide rail 100 and drives the knife holder mechanism 200, which includes an electromagnetic clutch mechanism 310. Through the use of the electromagnetic clutch mechanism 310, it can be ensured that all functions of the rubber tapping device can be achieved by using only one driving mechanism 300, thereby reducing production costs. The electromagnetic clutch mechanism 310 can respectively and accurately control the knife retracting assembly and the cutting track assembly to ensure that the rubber tapping device completes the knife retracting action or the spiral track cutting action, thereby improving the efficiency and accuracy of rubber tapping; specifically, the driving mechanism 300 can respectively drive the square rod 212 or the screw rod 222, the square rod 212 is used to control the knife retracting action, and the screw rod 222 is used to drive the spiral track of the entire rubber tapping device. Due to the setting of the electromagnetic clutch mechanism 310, the combined parts of the driving mechanism 300 are simpler and more efficient, and also have the characteristics of low cost and simple maintenance.

[0043] It should be noted that the retractable knife assembly includes a square rod driving gear 211 and a square rod 212, which can realize the retractable action of the rubber tapping blade; the cutting track assembly includes a screw driving gear 221, a screw rod 222 and a transmission gear respectively connected to the screw driving gear 221 and the guide rail 100, the screw driving gear 221 and the screw rod 222 are used to control the up and down movement of the knife holder mechanism 200, and the transmission gear is used to control the left and right movement of the knife holder mechanism 200, and the longitudinal and lateral mutual cooperation in the cutting track assembly ensures that the knife holder mechanism 200 completes the spiral track cutting movement.

[0044] In some embodiments of the present application, the electromagnetic clutch mechanism 310 includes a double-sided drive gear 311 and an electromagnetic switch 312. The double-sided drive gear 311 is connected to the electromagnetic switch 312. The electromagnetic switch 312 drives the double-sided drive gear 311 to connect to one of the retractable knife assembly and the cutting track assembly.

[0045] like Figure 2As shown, by interconnecting the double-sided driving gear 311 and the electromagnetic switch 312, an efficient and controllable driving system is formed. Among them, the design of the double-sided driving gear 311 allows the gear to receive the electromagnetic force generated by the electromagnetic switch 312 and transmit power to both sides, thereby enhancing the driving force and stability of the overall mechanism. The use of the electromagnetic switch 312 makes the control of the driving mechanism 300 more precise. The electromagnetic switch 312 can connect or disconnect the circuit in a very short time, thereby achieving a rapid response to the driving gear. The standardized electromagnetic switch 312 and gear assembly make maintenance and replacement work easier. In long-term use, this design helps to reduce maintenance costs and increase the service life of the equipment.

[0046] In some embodiments of the present application, the double-sided driving gear 311 includes a first driving gear 313 and a second driving gear 314 , and the electromagnetic switch 312 is provided with a transmission part 315 , which is provided between the first driving gear 313 and the second driving gear 314 .

[0047] like Figure 3 As shown, the double-sided driving gear 311 includes a first driving gear 313 and a second driving gear 314, which are respectively connected to the electromagnetic clutch for electromagnetic force transmission; the electromagnetic switch 312 is provided with a transmission part 315, which is arranged between the first driving gear 313 and the second driving gear 314 to coordinate and transmit power. The gear configuration of the first driving gear 313 and the second driving gear 314 allows for more precise power distribution and control, and each gear can be operated independently, thereby enhancing the flexibility of the entire rubber tapping device and the ability to cope with different rubber tapping situations. The setting of the transmission part 315 increases the interaction between the gears, helps to ensure the stable output of power, and reduces mechanical wear.

[0048] By controlling the first drive gear 313 and the second drive gear 314 respectively, the operation mode of the rubber tapping device can be adjusted more accurately, the power usage can be optimized, and the energy efficiency can be improved; the configuration of the double-sided drive gear 311 and the combination of the transmission part 315 enable the rubber tapping device to adapt to different operation requirements more flexibly, thereby improving the adaptability and versatility of the equipment; the setting of the transmission part 315 helps to reduce the friction and wear between the gears, extend the service life of the device, reduce the frequency of maintenance and replacement of parts, and thus reduce maintenance costs and downtime; through more precise power control and operational flexibility, the rubber tapping device can perform the tapping operation more accurately, thereby improving the consistency and quality stability of the product.

[0049] In some embodiments of the present application, when the electromagnetic switch 312 is powered off, the conductive part 315 is connected to one of the first drive gear 313 and the second drive gear 314; when the electromagnetic switch 312 is powered on, the conductive part 315 is connected to the other of the first drive gear 313 and the second drive gear 314.

[0050] like Figure 3 As shown, under the control of the electromagnetic switch 312, the electromagnetic connection switching between the conducting part 315 and the first drive gear 313 and the second drive gear 314 is realized in the power-off and power-on states. When the electromagnetic switch 312 is powered off, the conducting part 315 will establish a connection with one of the first drive gear 313 and the second drive gear 314, and when the electromagnetic switch 312 is powered on, the conducting part 315 will establish a connection with the other gear. This design makes it possible to flexibly switch the power transmission path under different working conditions, thereby realizing the power control of the rubber tapping device. Through this electromagnetic connection switching mechanism, it can be ensured that when the electromagnetic switch 312 is powered off or powered on, the power can be effectively transmitted to ensure the normal operation of the equipment. At the same time, this flexible connection method also enhances the reliability of the system and reduces the possibility of failure. In addition, depending on the working state, the power will only be transmitted to the currently required drive gear, avoiding unnecessary energy waste and improving the energy efficiency of the entire system.

[0051] For example, in the electromagnetic clutch, the double-sided drive gear 311 is connected to a spring, and the double-sided drive gear 311 is at the top when the spring is in a normal state, and the double-sided drive gear 311 is attracted to the bottom by the transmission part 315 after power is turned on. For another example, in the electromagnetic clutch, the double-sided drive gear 311 is connected to a spring, and the double-sided drive gear 311 is at the bottom when the spring is in a normal state, and meshes with the screw drive gear 221, and the double-sided drive gear 311 is pushed to the top under the attraction of the transmission part 315 after power is turned on, and meshes with the square rod drive gear 211.

[0052] In some embodiments of the present application, the first drive gear 313 is connected to the retractable knife assembly, and the second drive gear 314 is connected to the cutting track assembly.

[0053] like Figure 3As shown, by clearly connecting the first drive gear 313 with the knife assembly and the second drive gear 314 with the cutting track assembly, this configuration further optimizes the working efficiency and flexibility of the rubber tapping device. Among them, the first drive gear 313 is responsible for controlling the knife assembly, and transmitting power through electromagnetic connection, so that the knife bar can be accurately controlled as needed to ensure the accuracy and efficiency of the rubber tapping operation; the second drive gear 314 controls the cutting track assembly, and realizes power transmission through electromagnetic connection, making the cutting operation more stable and reliable, and more closely coordinated with other components. This connection method helps the coordination and cooperation between the knife assembly and the cutting track assembly, and improves the working efficiency and overall performance of the entire rubber tapping device.

[0054] In some embodiments of the present application, a first tooth 316 a is disposed on a side of the first driving gear 313 away from the transmission portion 315 ; and / or a second tooth 316 b is disposed on a side of the second driving gear 314 away from the transmission portion 315 .

[0055] like Figure 3 , 4 As shown, by providing teeth on both the first drive gear 313 and the second drive gear 314 on the side away from the transmission part 315, the functionality and operating efficiency of the gears can be enhanced. The first teeth 316a of the first drive gear 313 are used to connect or transmit with the square rod drive gear 211, and the second teeth 316b of the second drive gear 314 are used to connect or transmit with the screw drive gear 221. The tooth design on the double-sided drive gear 311 makes the connection with other components more convenient and efficient, thereby improving the operating efficiency and overall performance of the device. It should be noted that the shape of the first teeth 316a of the first drive gear 313 is adapted to the shape of the square rod drive gear 211, so as to ensure mutual meshing, so that the first drive gear 313 can drive the square rod drive gear 211 to rotate; the shape of the second teeth 316b of the second drive gear 314 is adapted to the shape of the screw drive gear 221, so as to ensure mutual meshing, so that the second drive gear 314 can drive the screw drive gear 221 to rotate.

[0056] In some embodiments of the present application, a notch 317 is provided on one end of the transmission portion 315 connected to the double-sided driving gear 311 , and the shape of the notch 317 is adapted to the circumferential shape of the double-sided driving gear 311 .

[0057] like Figure 2 , 3As shown in , 5, a notch 317 is provided on one end of the transmission part 315 connected to the double-sided drive gear 311, and the shape of the notch 317 is adapted to the circumferential shape of the double-sided drive gear 311. This design is intended to optimize the connection between the transmission part 315 and the drive gear and improve the performance and reliability of the device. The tight connection and precise fit between the transmission part 315 and the gear reduce friction and clearance during movement and improve transmission efficiency. Through this adapted notch 317 design, the connection between the transmission part 315 and the double-sided drive gear 311 is more stable and reliable, can withstand greater power and pressure, and reduces the risk of loosening or disconnection of the device during operation.

[0058] In some embodiments of the present application, the knife retracting assembly includes a square rod driving gear 211 and a square rod 212 on which the square rod driving gear 211 is sleeved, and the driving mechanism 300 includes a locking gear 320, which cooperates with the square rod driving gear 211 to lock the square rod 212.

[0059] like Figure 6-8 As shown, the square rod driving gear 211 is sleeved on the square rod 212 to drive the opposite rod 212, thereby controlling the position and movement trajectory of the knife rod. The locking gear 320 cooperates with the square rod driving gear 211 to lock the opposite rod 212, so that when the position of the knife rod needs to be fixed, the locking gear 320 can effectively fix the square rod 212 to ensure the accuracy and stability of the position of the knife rod. The design of the locking gear 320 can avoid accidental movement of the knife rod when it is not necessary to move the knife rod, thereby improving the safety and reliability of the operation.

[0060] In some embodiments of the present application, the locking gear 320 is provided with a first locking arc 321 , the square rod driving gear 211 is provided with a second locking arc 213 , and the first locking arc 321 and the second locking arc 213 are meshed with each other.

[0061] like Figure 6-8 As shown, the locking arcs respectively arranged on the locking gear 320 and the square rod driving gear 211 are used to mesh with each other during operation to form a stable connection to fix the position and movement state of the square rod 212. The first locking arc 321 and the second locking arc 213 mesh with each other to form two states. When the first driving gear 313 cuts off the power, the knife holder mechanism 200 remains in one of the two states of knife collection or knife release; in addition, the tight connection between the locking gear 320 and the square rod driving gear 211 is ensured, and the stability and reliability of the device during operation are improved. Through the meshing between the locking gear 320 and the square rod driving gear 211, the position and movement trajectory of the knife bar can be accurately controlled, thereby achieving precise rubber tapping operations.

[0062] In some embodiments of the present application, the locking gear 320 is provided with two first locking arcs 321, and the square rod driving gear 211 is provided with two second locking arcs 213, so as to perform knife retracting operation and knife releasing operation.

[0063] like Figure 6-8 As shown, two locking arcs are respectively provided on the locking gear 320 and the square rod driving gear 211, which are used to mesh with each other during the knife-retracting operation and the knife-releasing operation to form a more solid connection to ensure the accurate movement of the knife bar extending or retracting. Through the design of the two locking arcs, more flexible knife control can be achieved during the knife-retracting or knife-releasing operation, so that the rubber tapping device can adapt to different work requirements and operation scenarios.

[0064] The knife-retracting operation is the process of retracting the knife bar in the rubber tapping device to a set position or state, so as to ensure that the knife bar completes the knife-retracting process under the control of the locking gear 320, and there is no shaking or deviation after the operation is completed. The knife-releasing operation is the process of moving the knife in the rubber tapping device to a working position or state. In this process, the knife needs to be accurately positioned at the position where cutting is required to complete the cutting of the rubber tree.
