Description

Technical Field

[0001] The utility model relates to the field of automatic rubber tapping machines, in particular to an automatic rubber tapping machine. Background Art

[0002] Rubber tapping is a process of collecting rubber juice by making an incision on the bark of a rubber tree. Usually, a thin layer of the rubber bark is generally cut off with a manual rubber tapping knife. The bark of a rubber tree is systematically cut to a certain width and depth in a channel-shaped position. After the incision is made on the tree, latex begins to flow out, and can be collected in a container attached to the tree. After a few hours on the surface of the bark, a clot is formed in the incision, thereby the exudation of latex can be stopped. In order for latex to flow out, a small layer of bark or clot needs to be removed from the incision. Regularly repeat this process to obtain maximum latex from the incision.

[0003] Based on the above problems, someone invented an automatic rubber tapping machine to replace manual rubber tapping. After testing, the existing automatic rubber tapping machine has the following defects:

[0004] 1. Usually, an x-axis motor and a y-axis motor are used together to drive the rubber tapping knife to tap rubber on a constant trajectory. However, the speed ratio of the x-axis motor and the y-axis motor is constant and cannot be adjusted. When encountering trees with different outer diameters, it is impossible to adapt to the corresponding trees to drive the rubber tapping knife to adjust to the tapping trajectory of the corresponding tree diameter angle. It is necessary to frequently replace the x-axis motor and the y-axis motor of the corresponding speed to adapt to different tree diameters. Frequent replacement of motors with different speed ratios leads to high tapping costs.

[0005] 2. The speed ratio of the x-axis motor and the y-axis motor is in a constant and unadjustable state. When encountering trees with different outer diameters, it is unable to adapt to the corresponding trees to drive the tapping knife to adjust the tapping trajectory to the corresponding tree diameter angle. The angle of the cutting knife mechanism needs to be adjusted frequently to adapt to different tree diameters. Therefore, the angle of the cutting knife mechanism needs to be adjusted frequently, resulting in low tapping efficiency.

[0006] 3. When encountering trees with different outer diameters, since the speed ratio of the x-axis motor and the y-axis motor is in a constant and unadjustable state, it is impossible to adapt to the corresponding trees to drive the tapping knife to adjust the tapping walking trajectory to the corresponding tree diameter angle. Therefore, the existing automatic rubber tapping machine has poor adaptability.

[0007] 4. Since the speed ratio of the x-axis motor and the y-axis motor is in a constant and unadjustable state, it is unable to adapt to the corresponding tree to drive the tapping knife to adjust to the tapping walking trajectory of the corresponding tree diameter angle. The tapping knife with a constant angle walking trajectory is unadjustable, resulting in a poor angle for collecting the rubber flowing from the tree after tapping, which affects the quality of tapping.

[0008] 5. The cutting knife mechanism on the existing automatic rubber tapping machine usually adopts a constant guide block structure, but the constant guide block structure has a poor tapping effect; when encountering trees with uneven outer diameters during tapping, the rubber will not be tapped in place, resulting in low tapping efficiency.

[0009] 6. The cutting knife mechanism on the existing automatic rubber tapping machine usually adopts a cam structure to drive the rubber tapping knife to advance / retreat to achieve the function of approaching or moving away from the tree epidermis. However, the advance / retreat accuracy of the rubber tapping knife driven by the cam structure is poor, which affects the rubber tapping efficiency. Utility Model Content

[0050] Working principle of this utility model:

[0051] First, the scheme is installed on the trees that need to be tapped through the upper clamp 3a and the lower clamp 3b, and then the tapping action is controlled by the circuit control system 1. The electronic gear ratio module uses the logic algorithm implemented by the parameterized equation of the scheme to adjust the x transmission shaft drive motor 04 and the y screw drive motor 05 to spiral tapping trajectories of different angles according to actual needs, thereby driving the cutter mechanism 8 to perform the best tapping walking route; the setting of the electronic gear ratio module of the scheme has the following advantages: 1. Through the electronic gear ratio module, the x transmission shaft drive motor 04 and the y screw drive motor 05 of the scheme can adjust the speed ratio, drive the cutter mechanism 8 to achieve tapping walking trajectories of different angles, thereby achieving the functional effect of adjustable tapping trajectories. 2. Through the electronic gear ratio module, the x transmission shaft drive motor 04 and the y screw drive motor 05 of the scheme can adjust the speed ratio, drive the cutter mechanism 8 to achieve tapping walking trajectories of different angles, and there is no need to manually adjust the angle position of the cutter mechanism 8 frequently, thereby improving the tapping efficiency. 3. When dealing with trees with different outer diameters, the electronic gear ratio module of this product can adjust the speed ratio of the x-drive shaft drive motor 04 and the y-screw drive motor 05 to adapt to trees with different outer diameters, thereby improving adaptability. 4. By adjusting the speed ratio of the x-drive shaft drive motor 04 and the y-screw drive motor 05 through the electronic gear ratio module, this solution can achieve the best angle of the rubber tapping knife 82 walking trajectory, so that the rubber collected from the tapped trees is optimal, thereby improving the quality of rubber tapping.

[0052] Secondly, the cutting knife mechanism 8 controls the cutting knife forward / backward motor 87 through the circuit control system 1 to drive the elastic stretching member 84 through the swing arm 88 to drive the rubber cutting knife 82 on the knife holder 81 to perform the rubber cutting forward action; when encountering a tree with an uneven outer diameter, the guide block 83 first contacts the uneven tree, and the elastic member 85 cooperates with the guide block rotating shaft 831 to drive the guide block 83 to perform adaptive rotation between the fork arms 813, and the double fork arm 813 structure reserves adaptive rotation space for the guide block 83, thereby completing the rubber cutting of the tree with an uneven outer diameter with the rubber cutting knife 82. This technical solution avoids the damage to the cutting knife mechanism 8 caused by the tree with an uneven outer diameter during rubber tapping, thereby increasing the service life of this product. After the rubber tapping is completed, the circuit control system 1 controls the cutting knife advance / retract motor 87 to drive the elastic stretching member 84 through the swing arm 88 to drive the rubber tapping knife 82 on the knife holder 81 to perform the rubber tapping and retracting action. The swing arm 88 cooperates with the double-link linkage structure of the elastic stretching member 84 to make the advance / retract action of the present scheme more accurate; therefore, the efficiency of rubber tapping is improved.

[0053] Furthermore, the fixing member 86 passes through the fixing hole 812 to fix the tool holder 81 to the side of the middle base 7b to prevent it from shaking up and down during rubber tapping.

[0054] Furthermore, the elastic stretching member 84 is a tension spring.

[0055] Further, at least one guide protrusion is formed on the side of the guide block 83, and the rubber tapping knife 82 is installed on the guide block 83 behind the guide protrusion along the axis. As shown in the figure, the guide protrusion is a knife tip-like structure, and when used for rubber tapping, the guide block 83 imitates the rubber tapping knife 82 to first contact the tree to be tapped, thereby playing a guiding role.

[0056] Furthermore, the planar area of ​​the guide block 83 when viewed from above is larger than the planar area of ​​the guide block shaft 831, so that the rubber tapping knife 82 installed on the guide block 83 can be farther away from the fork arm 813 or the guide block shaft 831, which can effectively avoid the problem of chip blockage caused by the close distance between the two during rubber tapping.

[0057] Furthermore, the rubber tapping knife 82 also includes a knife pressing block 822, and the knife pressing block 822 fastens the rubber tapping knife 82 to the guide block 83 through a screw 821. The knife pressing block 822 has the functions of fastening the rubber tapping knife 82 to the guide block 83 and effectively preventing debris from entering the rubber tapping knife to cause chip blockage.

[0058] Furthermore, at least two position sensors 81 are arranged at 180° in the middle base 7b, which are a sensor 81 for tool feeding and a sensor 81 for tool retracting.

[0059] Furthermore, it also includes a photovoltaic charging panel 9, which is connected to the circuit control system 1 and installed on the top base 7a for emergency power supply.

[0060] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
