Description

Technical Field

[0001] This invention belongs to the technical field of contour rubber tapping blades, specifically a contour rubber tapping blade that facilitates rubber tapping operations. Background Technology

[0002] Natural rubber is a type of latex collected manually by tapping the bark of rubber trees in the early morning. The original method of rubber tree harvesting evolved from felling trees with axes to the invention of continuous tapping from the original cut in 1897, with the technology constantly being improved. Tapping and latex production are closely linked, requiring tappers to maintain production while ensuring the rubber trees can be recycled.

[0003] Rubber tapping has become a skilled trade. It takes ten or even more than ten years of continuous day and night training for an ordinary rubber tapper to become a skilled rubber tapper. This shows that rubber tapping has a high technical threshold and the work is extremely arduous, involving the constant repetition of the same actions.

[0004] How to ensure the quality of rubber tapping while lowering the technical threshold for tapping and reducing the labor intensity of rubber tappers has become a technical challenge since the emergence of rubber tapping technology. Summary of the Invention

[0005] The purpose of this invention is to provide a contour-following rubber tapping head that facilitates rubber tapping operations in order to solve the problems mentioned above.

[0006] The technical solution adopted in this invention is as follows: a contoured rubber tapping head that facilitates rubber tapping operations, comprising a head base, one end of which is connected to a rubber tapping blade via a fixing frame, and the other end of which is provided with a skin consumption control component; the skin consumption control component consists of front and rear sliders and upper and lower sliders, the front and rear sliders being slidably engaged with the head base, and the upper and lower sliders being perpendicularly connected to the front and rear sliders.

[0007] By adopting the above technical solution, the bark consumption control component consists of front and rear sliders and upper and lower sliders. By adjusting the position perpendicular to the tapping direction and the tapping plane, the cutting depth and bark consumption thickness of the blade are precisely controlled, avoiding damage to the tree or insufficient yield. The front and rear sliders slide horizontally along the groove of the cutter head base. Through the virtual linear positioning function, it is ensured that the blade is always perpendicular to the surface of the rubber tree during tapping, preventing deviation of the tapping trajectory due to uneven bark. Preferably, a blade assembly is installed inside the cutter head base. The blade assembly includes a blade base and a blade, and the blade is detachably fixed to the blade base.

[0008] By adopting the above technical solution, the blade assembly includes a blade base and a blade. As the core cutting component, the blade extension length can be adjusted by sliding within the groove of the blade base to adapt to the tapping needs of different rubber trees, and the position can be quickly locked by the pressure block assembly. The blade base is used to fix and support the blade, and its groove design allows the blade to be finely adjusted along the tapping direction. With the help of the locking nut, the blade extension length can be precisely locked to ensure consistent cutting depth.

[0009] Preferably, the blade assembly is connected to the blade base via a pressure block assembly; the pressure block assembly includes a pressure rod and a pressure block, one end of the pressure rod is hinged to the blade base, and the other end engages with the pressure block via an elastic washer.

[0010] By adopting the above technical solution, the pressure block assembly consists of a pressure rod, a pressure block, and an elastic washer. The pressure rod rotates to drive the pressure block to press down on the blade assembly, and the dead-point protrusion structure quickly locks the blade position, preventing the blade from loosening during cutting. The pressure block acts directly on the blade base, and the elastic washer's deformation buffers the pressure, pressing the blade assembly firmly into the cutter head base under the pressure rod's drive, ensuring no blade displacement during cutting. The elastic washer is installed between the pressure block and the blade base, absorbing the impact force of the pressure rod's downward pressure through elastic deformation, avoiding blade damage caused by rigid contact, and providing fine-tuning allowance to compensate for component machining errors.

[0011] Preferably, the outer surface of the cutter head base is provided with a contour guide structure, which is an arc-shaped protrusion used to conform to the undulations of the rubber tree surface.

[0012] By adopting the above technical solution, the blade base serves as the main support structure of the contour rubber tapping blade. It is designed with slots and arc-shaped protrusions, which not only provide a mounting base for each component, but also guide it along the undulations of the rubber tree surface, ensuring that the blade is always perpendicular to the rubber cutting plane and avoiding uneven tapping depth.

[0013] Preferably, the fixing frame is detachably connected to the rubber cutting knife by bolts, and an angle adjustment mechanism is provided between the fixing frame and the knife head base.

[0014] By adopting the above technical solution, one end of the fixing frame is fixedly connected to the rubber cutting knife with bolts, and the other end is engaged with the blade base screw, so that the entire contouring blade head is stably installed on the rubber cutting knife. It can be adapted to traditional manual rubber cutting knives or electric rubber cutting knives, and can achieve quick changeover.

[0015] Preferably, the blade base has a sliding groove, the blade is slidably connected to the blade base through the sliding groove, and the position is fixed by a locking nut.

[0016] By adopting the above technical solution, the blade is designed to be detachable and fixed to the blade base with bolts. It directly contacts the rubber tree bark for cutting. Its sharpness and angle determine the rubber tapping efficiency, and different models can be replaced according to the hardness of the bark.

[0017] Preferably, the contact surface between the pressure rod and the pressure block is provided with a dead point protrusion structure for locking the position of the blade assembly.

[0018] By adopting the above technical solution, the pressure rod serves as an operating handle, driving the pressure block to press or release the blade assembly through rotational motion. The dead point design of its contact surface with the pressure block ensures the stability of the blade in the locked state, and the blade can slide freely for adjustment when unlocked.

[0019] Preferably, the upper and lower sliders of the leather consumption control component are provided with scale markings.

[0020] By adopting the above technical solution, the upper and lower sliders slide perpendicular to the rubber tapping plane, and the depth of the blade cutting into the bark is quantitatively adjusted by the scale markings. With the buffering effect of the elastic pad, the bark thickness is controlled with millimeter-level precision.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] In this invention, by adjusting the front-to-back and up-to-down distances of the bark control component, the thickness of the bark consumed and the depth of tapping can be stabilized, avoiding uneven thickness and depth during tapping, which can lead to unstable yields or even damage to the trees. This invention also includes a quick-locking and unlocking pressure rod and plate, allowing for rapid adjustment of the blade assembly's extension and retraction to achieve different tapping depths when tapping different rubber trees. When using the contour tapping head, its base also has an anti-shaping function, enabling the contour tapping head to better conform to the shape of the rubber tree surface for anti-shaping tapping operations.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example:

[0034] Reference Figure 1-8 One end of the blade base 4 is connected to the rubber tapping blade via a fixing bracket 5, and the other end is equipped with a bark loss control component 10. The bark loss control component 10 consists of a front and rear slider 11 and an upper and lower slider 12. The front and rear slider 11 slides in engagement with the blade base 4, and the upper and lower slider 12 is perpendicularly connected to the front and rear slider 11. The bark loss control component 10, composed of the front and rear slider 11 and the upper and lower slider 12, precisely controls the cutting depth and bark loss thickness of the blade by adjusting its position perpendicular to the rubber tapping direction and the upper and lower position of the rubber tapping plane, thus avoiding damage to the tree or insufficient yield. The front and rear slider 11 slides horizontally along the groove of the blade base 4, and through a virtual linear positioning function, ensures that the blade is always perpendicular to the surface of the rubber tree during the tapping process, preventing deviation of the tapping trajectory caused by the unevenness of the bark.

[0035] Reference Figure 1-8The blade assembly 20 is installed within the cutter head base 4. The blade assembly 20 includes a blade base 21 and a blade 22, with the blade 22 detachably fixed to the blade base 21. As the core cutting component, the blade assembly 20, comprising the blade base 21 and the blade 22, can slide and adjust its extension length within the groove of the cutter head base 4 to adapt to the tapping requirements of different rubber trees, and its position is quickly locked by the pressure block assembly 30. The blade base 21 is used to fix and support the blade 22. Its groove design allows for fine adjustment of the blade along the tapping direction, and the locking nut enables precise locking of the blade extension length, ensuring consistent cutting depth.

[0036] Reference Figure 1-8 The blade assembly 20 is connected to the cutter head base 4 via a pressure block assembly 30. The pressure block assembly 30 includes a pressure rod 31 and a pressure block 32. One end of the pressure rod 31 is hinged to the cutter head base 4, and the other end engages with the pressure block 32 via an elastic washer 33. The pressure block assembly 30 consists of the pressure rod 31, the pressure block 32, and the elastic washer 33. The pressure rod rotates to drive the pressure block to press down on the blade assembly 20, using a dead-point protrusion structure to quickly lock the blade position and prevent the blade from loosening during cutting. The pressure block 32 acts directly on the blade base 21. The deformation of the elastic washer 33 buffers the pressure, and under the drive of the pressure rod 31, the blade assembly 20 is pressed tightly into the cutter head base 4, ensuring that the blade does not shift during cutting. The elastic washer 33 is installed between the pressure block 32 and the blade base 21. Through elastic deformation, it absorbs the impact force of the pressure rod 31 pressing down, avoiding blade damage caused by rigid contact, and providing a fine-tuning allowance to compensate for component machining errors.

[0037] Reference Figure 1-8 The outer surface of the cutter head base 4 is provided with a contour guide structure, which is an arc-shaped protrusion used to conform to the undulations of the rubber tree surface. The cutter head base 4 serves as the main support structure for the contour tapping cutter head, and it is designed with grooves and arc-shaped protrusions. This provides a mounting base for each component and guides the cutter along the undulations of the rubber tree surface, ensuring that the blade is always perpendicular to the tapping plane and avoiding uneven tapping depth.

One end of the fixing frame 5 is fixedly connected to the rubber tapping knife by bolts, and the other end is engaged with the blade base 4 by screws, so that the entire contour blade is stably installed on the rubber tapping knife, and it can be adapted to traditional manual rubber tapping knives or electric rubber tapping knives, so as to achieve quick changeover.

[0039] Reference Figure 1-8The blade base 21 has a sliding groove, and the blade 22 is slidably connected to the blade base 21 through the sliding groove and fixed in position by a locking nut. The blade 22 adopts a detachable design and is fixed to the blade base 21 by bolts. It directly contacts the rubber tree bark for cutting. Its sharpness and angle determine the rubber tapping efficiency, and different models can be replaced according to the hardness of the bark.

[0040] Reference Figure 1-8 The contact surface between the pressure rod 31 and the pressure block 32 is provided with a dead-point protrusion structure for locking the position of the blade assembly 20. The pressure rod 31 acts as an operating handle, driving the pressure block 32 to press or release the blade assembly 20 through rotational movement. The dead-point design of its contact surface with the pressure block ensures the stability of the blade in the locked state, and the blade can slide freely for adjustment when unlocked.

[0041] Reference Figure 1-8 The upper and lower sliders 12 of the bark loss control component 10 are provided with scale markings. The upper and lower sliders 12 slide perpendicular to the rubber tapping plane. The depth of the blade cutting into the bark is quantitatively adjusted by the scale markings. With the buffering effect of the elastic pads 33, the bark loss thickness is controlled with millimeter-level precision.

[0042] The implementation principle of the contour-following rubber tapping head embodiment of the present invention, which is beneficial to rubber tapping operations, is as follows:

This invention also includes a quick-locking and unlocking pressure rod and plate, allowing for rapid adjustment of the blade assembly's extension and retraction to achieve different tapping depths when tapping different rubber trees. When using the contour tapping head, its base also has an anti-shaping function, enabling the contour tapping head to better conform to the shape of the rubber tree surface for anti-shaping tapping operations.
