Description

Technical Field

[0001] This invention relates to the field of agricultural and forestry machinery technology, and in particular to an electric girdling tool for the bark of the dragon's blood tree. Background Technology

[0002] Dragon's blood resin is a traditional and precious Chinese medicine, known as the "holy medicine for promoting blood circulation." It possesses properties such as promoting blood circulation, removing blood stasis, relieving pain, stopping bleeding, and promoting tissue regeneration. It is widely used in orthopedics, gynecology, and trauma treatment, with a history of over 1500 years. More than 70 kinds of drugs are marketed using it as a raw material, and it has a long medicinal tradition in Asia, Africa, and the Americas. Dragon's blood resin comes from plants of the *Dracaena* genus. Its medicinal resin can only be formed after the tree is physically damaged or artificially induced. Currently, an artificially induced production technology for dragon's blood resin has been developed: First, the stems and branches of the dragon's blood tree that have reached a certain thickness are girdled, meaning the bark of a certain width is completely removed around the branch. Then, an inducing agent is sprayed on the girdled area to promote the formation of red resin rich in dragon's blood resin on the wound surface. Once the resin layer hardens to about 1 cm in thickness, it is manually harvested and collected, ultimately extracting the commercial dragon's blood resin. Therefore, girdling the bark and harvesting the hardened resin are two interconnected core processes in the production of dragon's blood resin.

[0003] With the continued growth in market demand for dragon's blood resin, traditional manual methods are no longer sufficient to meet the requirements of large-scale production. Currently, the aforementioned girdling and harvesting processes rely entirely on manual labor. Workers typically use simple tools such as sickles, shovels, or homemade peeling scrapers, relying on physical strength to repeatedly cut and pry around the branches. This purely manual labor method presents a series of prominent technical problems: First, the labor intensity is extremely high, and the work efficiency is very low. A skilled worker can only process a very limited number of branches per day, making it difficult to meet the ever-increasing production capacity demand, resulting in high labor costs. Second, the quality of girdling is difficult to precisely control. Dragon's blood resin branches vary greatly in thickness (the diameter of branches processed in production is generally above 5 cm, commonly 5-15 cm), and the bark thickness and toughness also vary. The depth of manual cutting is easily uneven. Cutting too deep will damage the xylem and cambium, hindering nutrient transport and leading to weakened tree vigor or even death; cutting too shallow will result in incomplete bark removal, leaving phloem tissue, significantly reducing the success rate of induction and the yield of dragon's blood resin. Third, the process of harvesting resin is even more challenging. The artificially induced dragon's blood resin layer is extremely hard and adheres tightly to the surface of the wood. Scraping it by hand is extremely laborious, easily tiring workers, and often results in resin blocks breaking and residue due to uneven force, leading to significant collection losses. In addition, different curvature tools or repeated adjustments to the technique are often required for branches of different diameters, resulting in poor operational consistency and difficulty in standardizing the quality of the work. Summary of the Invention

[0004] The purpose of this invention is to provide an electric girdling tool for the bark of dragon's blood tree, which aims to mechanize and automate the girdling operation, thereby reducing labor intensity, improving work efficiency, and precisely controlling the cutting depth and peeling force, adapting to branches of different diameters, and ensuring uniform and standardized work quality.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: By adopting the above technical solution, an electric girdling tool for dragon's blood tree bark includes a support member, a clamping member on the left side of the support member, a circular clamping cavity extending through the support member and the clamping member, a power component on the support member, the power component driving the clamping member to move left and right to open and close the clamping cavity, a first cutting component, a moving component, a second cutting component, and a peeling component are provided in the clamping cavity, the first cutting component is used to girdle the bark, the moving component is used for the support member and the clamping member to move on the branch, the second cutting component is used to cut the bark along the length of the branch, the peeling component is used to remove the bark, a handle is provided on the right side of the support member, and a control panel electrically connected to the power component, the first cutting component, the moving component, the second cutting component, and the peeling component is provided on the handle.

[0006] By adopting the above technical solution, the operator holds the handle and activates the power unit via the control panel, causing the clamping parts to open and placing the branch to be girdled into the clamping cavity. Subsequently, the moving components can be controlled sequentially or in concert to move the tool on the branch to the designated position. The first and second cutting components then perform circumferential and axial cuts on the bark, respectively. Finally, the peeling component removes the cut bark. The entire process is electrically controlled, standardized, and significantly reduces labor intensity while improving efficiency.

[0007] A further configuration of the present invention is as follows: a support bar extends to the left from the upper end of the support member, a groove is provided at the lower end of the support bar, a slide bar is provided at the upper end of the clamping member, the slide bar is slidably connected to the groove, the power assembly includes a first rotating motor and a screw, the left end of the screw is inserted into the slide bar, the screw and the slide bar form a threaded engagement, the right end of the screw is connected to the output shaft of the first rotating motor, the first rotating motor is disposed in the support bar, and the first rotating motor is electrically connected to the control panel.

[0008] By adopting the above technical solution, the first rotating motor drives the screw to rotate. Under the guidance of the threaded engagement and the sliding groove and the slide bar, the rotation is accurately converted into the linear movement of the clamping part, thereby realizing the stepless adjustment of the opening and closing size of the clamping cavity. It can firmly clamp the branches of dragon blood trees of different diameters and has strong adaptability.

[0009] A further configuration of the present invention is as follows: at least three moving components are provided and evenly distributed within the clamping cavity along the inner side of the clamping cavity. Each moving component includes a first telescopic motor, a first pressure sensor, and a first electric wheel. The first telescopic motor is radially disposed within the clamping cavity. One end of the first telescopic motor is connected to the inner wall of the clamping cavity, and the other end of the first telescopic motor is connected to the first electric wheel through the first pressure sensor. The axis of the first electric wheel is perpendicular to the axis of the clamping cavity. The first telescopic motor, the first pressure sensor, and the first electric wheel are all electrically connected to the control panel.

[0010] By adopting the above technical solution, multiple first telescopic motors can extend and retract independently or synchronously, driving the first electric wheels to press against the surface of the branches. The first pressure sensor can detect the pressing force in real time and feed it back to the control panel. Through closed-loop control, all first electric wheels drive the tool to move steadily along the branches with constant and appropriate friction, preventing slippage and avoiding excessive pressure that could damage the wood.

[0011] A further feature of the present invention is that the cross-section of the first electric wheel is concave, with larger ends and a smaller middle.

[0012] By adopting the above technical solution, the concave cross-section design increases the contact area and fit between the first electric wheel and the surface of the branch, improving the stability and traction of movement, and is especially suitable for cylindrical or slightly curved branch surfaces.

[0013] A further configuration of the present invention is as follows: the second cutting assembly includes an extension plate, a second telescopic motor, and a first blade. The extension plate is disposed at one end of the first telescopic motor near the first pressure sensor. The second telescopic motor is disposed on the extension plate radially along the clamping cavity. The first blade is disposed at one end of the second telescopic motor near the axis of the clamping cavity. Both the front and rear ends of the first blade are provided with cutting edges. The second telescopic motor is electrically connected to the control panel.

[0014] By adopting the above technical solution, the second cutting component is directly mounted on the extension plate of the moving component, resulting in a compact structure. After the moving component grips the branch, the second telescopic motor extends the first blade to cut into the bark. The first blade has cutting edges at both ends, allowing the tool to perform axial bark cutting regardless of whether it moves forward or backward, providing flexible operation.

[0015] A further configuration of the present invention is as follows: an annular moving groove is provided on the inner side of the clamping cavity. The moving groove is divided into two semi-circular rings and is respectively disposed on the support member and the clamping member. The first cutting assembly includes two racks, two second rotating motors, two gears, multiple third telescopic motors, and multiple second blades. The two racks are semi-circular arcs and are respectively disposed in the moving groove. The two second rotating motors are respectively disposed in the support member and the clamping member. The two gears are respectively disposed on the output shafts of the two rotating motors and mesh with the two racks in a one-to-one correspondence. The multiple third telescopic motors are evenly disposed on the inner side of the racks along the radial direction of the clamping cavity. One end of the third telescopic motor is connected to the rack. The second blade is disposed at the other end of the third telescopic motor. Both sides of the second blade are provided with cutting edges. The second rotating motors are electrically connected to the control panel.

[0016] By adopting the above technical solution, during circumcision, the third telescopic motor extends, allowing the second blade to insert into the bark to the designated depth. Subsequently, the second rotary motor drives the gear to rotate, causing the arc-shaped rack to rotate semi-circularly along the moving groove, thus rotating the second blade around the branch to complete half a circle of circumcision. With each of the two sets of mechanisms within the support and clamping components completing half a circle, a full circle of circumcision is achieved. The second blade has cutting edges on both sides, allowing it to cut in both clockwise and counterclockwise rotations, simplifying control. All third telescopic motors can independently control the depth, perfectly adapting to situations where branches are not perfectly round or bark thickness is uneven.

[0017] A further configuration of the present invention is as follows: the peeling components are provided in multiple and evenly distributed within the clamping cavity, each peeling component including a fourth telescopic motor, a second pressure sensor, and a second electric wheel. The fourth telescopic motor is radially disposed within the clamping cavity, one end of the fourth telescopic motor is connected to the inner wall of the clamping cavity, and the other end of the fourth telescopic motor is connected to the second electric wheel through the second pressure sensor. The axis of the second electric wheel is parallel to the inner wall of the clamping cavity. The fourth telescopic motor, the second pressure sensor, and the second electric wheel are all electrically connected to the control panel.

[0018] By employing the above technical solution, after the bark is girdled and axially cut, the fourth telescopic motor extends, causing the second electric wheel to press against the bark surface with a certain pressure. Since the rotation axis of the second electric wheel is parallel to the branch axis, when the second electric wheel rotates, it generates a rubbing and peeling force on the bark along the circumference of the branch. A second pressure sensor is used to monitor the peeling pressure, ensuring that the bark is effectively peeled without damaging the xylem.

[0019] A further configuration of the present invention is as follows: there are three of each of the moving component and the peeling component, the moving component is located in the middle of the clamping cavity, the peeling component is located behind the moving component, and the peeling component and the moving component are arranged alternately.

[0020] By adopting the above technical solution, the moving component provides core support for propulsion and guidance in the middle, and the peeling components are staggered behind it. They can immediately peel off the bark that has been cut behind while the moving component is moving. The layout is reasonable, the functions are closely connected, structural interference is avoided, and the force is evenly distributed on the circumference.

[0021] A further configuration of the present invention is that the second cutting component is disposed on the front side of the moving component, and the first cutting component is disposed on the front side of the second cutting component.

[0022] By adopting the above technical solution, when the tool moves forward, the work sequence is as follows: the first cutting component at the front completes the girdling of the bark, followed by the second cutting component completing the axial cutting, and finally the peeling component in the middle and rear peels off the cut bark. This front-to-back assembly line layout allows the girdling operation to be completed in one go, greatly improving work efficiency.

[0023] A further provision of the present invention is that: one end of the handle away from the support is electrically connected to a wire, the other end of the wire is connected to a battery, and the battery is electrically connected to the control panel via the wire.

[0024] By adopting the above technical solution, the battery can be placed on the body or on the ground, freeing it from the constraints of mains cables and improving the portability and operational flexibility of the tool in complex environments such as forests and wilderness.

[0025] In summary, the present invention has the following beneficial effects: Firstly, this invention integrates clamping, moving, circumferential cutting, longitudinal cutting, and peeling functions into one unit. It is operated through a control panel to achieve mechanized circumferential peeling, which greatly reduces labor intensity and improves work efficiency, demonstrating the advantages of high integration and automation.

[0026] Secondly, the invention is highly adaptable and produces high-quality work. The opening and closing dimensions of the clamping cavity are adjustable, and the extension amount and pressure of each cutting and peeling component can be controlled by a closed-loop sensor. It can accurately adapt to branches with different diameters of 5-15 cm and bark of different thicknesses, ensuring that the cutting depth is just right, without damaging the cambium, and the bark can be peeled off cleanly, significantly improving the success rate of induction.

[0027] Thirdly, the present invention arranges the functional components from front to back in the order of "ring cutting - longitudinal cutting - peeling". The tool can complete the entire ring-peeling process in one pass, and the operation is continuous and smooth. Of course, the various functional components can also work together to collect dragon's blood.

[0028] Fourth, when the second electric wheel in this invention rotates, it generates a rubbing and peeling force on the bark along the circumference of the branch. The second pressure sensor is used to monitor the peeling pressure to ensure that the bark is effectively peeled without damaging the wood, thus guaranteeing the peeling effect.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0034] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] Example: An electric girdling tool for dragon's blood tree bark, such as... Figure 1 and Figure 2 As shown, it includes a support member 1 and a clamping member 2. A handle 8 is fixedly connected to the right side of the support member 1. The handle 8 integrates a control panel 9 and is connected to a portable battery 101 via a wire 10 for convenient operation in forests. Figure 3 As shown, a support strip 12 extends to the left from the upper end of the support member 1, and a groove 13 is formed on the lower surface of the support strip 12. The top of the clamping member 2 is provided with a slide bar 21 that matches the groove 13, and the slide bar 21 is slidably installed in the groove 13. The opposing surfaces of the support member 1 and the clamping member 2 are both concave arc surfaces, and when they are closed, they form a circular clamping cavity 11 that runs through the front and back.

[0036] A power assembly 3 is installed inside the support bar 12 to drive the opening and closing of the clamping member 2. Figure 3 As shown, the power assembly 3 includes a first rotating motor 31 and a screw 32. The first rotating motor 31 is fixed inside the right end of the support bar 12, and its output shaft is connected to the right end of the screw 32. The left end of the screw 32 extends into and engages with the threaded hole in the slide bar 21. When the operator starts the first rotating motor 31 through the control panel 9, the screw 32 rotates, driving the slide bar 21 under the action of the thread, which in turn drives the entire clamping member 2 to move left and right along the slide groove 13, thereby precisely adjusting the opening and closing of the clamping cavity 11, making it convenient to clamp the tree branch into the clamping cavity 11.

[0037] Inside the clamping cavity 11, the first cutting component 4, the second cutting component 6, the moving component 5, and the peeling component 7 are arranged sequentially from front to back.

[0038] like Figure 4As shown, an annular moving groove 14 is formed on the inner wall of the clamping cavity 11 near the foremost position. This moving groove 14 is formed by the combination of an upper semicircular groove on the support member 1 and a lower semicircular groove on the clamping member 2. The first cutting assembly 4 includes two arc-shaped racks 41, which are slidably embedded in the upper and lower semicircular grooves respectively. A second rotating motor 42 is fixedly installed inside the support member 1 and the clamping member 2, and a gear 43 is mounted on the output shaft of each second rotating motor 42. The two gears 43 pass through the groove wall and mesh with the corresponding arc-shaped racks 41. On the inner arc surface of each arc-shaped rack 41, a plurality of third telescopic motors 44 are evenly fixed radially, and a second blade 45 is fixed to the end of the telescopic rod of each third telescopic motor 44. The second blade 45 has cutting edges on both the left and right sides. During operation, the control panel 9 controls all the third telescopic motors 44 to extend, inserting the second blade 45 into the bark with a set pressure. Then, the two second rotating motors 42 are activated to drive the arc-shaped rack 41 to rotate, causing the second blade 45 to circle the branch once, completing a precise depth circumferential cut. In this embodiment, there are three third telescopic motors 44 and two blades 45. Other numbers of third telescopic motors 44 and second blades 45 can also be used without affecting the scope of protection of this invention.

[0039] like Figure 4 As shown, three moving components 5 are evenly arranged along the circumference of the inner wall of the clamping cavity 11, immediately behind the first cutting component 4. Each moving component 5 includes a first telescopic motor 51 fixed radially. The end of the telescopic rod of the first telescopic motor 51 is connected to a first electric wheel 53 via a first pressure sensor 52. The rotation axis of the first electric wheel 53 is perpendicular to the axis of the clamping cavity 11, enabling it to drive the tool to move axially along the branch. The wheel surface of the first electric wheel 53 is designed as a concave arc shape, larger at both ends and smaller in the middle, to better conform to the surface of the branch. Figure 5 As shown, at the end of the first telescopic motor 51 of one of the moving components 5, a forward-extending extension plate 61 is fixed, and the second cutting component 6 is mounted on this plate. The second cutting component 6 includes a second telescopic motor 62 fixed radially to the extension plate 61, and a first blade 63 is mounted at the end of its telescopic rod. The cutting edge of the first blade 63 faces both the front and rear ends. When the moving component 5 extends radially to hold the branch, the second telescopic motor 62 extends further, so that the first blade 63 can cut into the bark longitudinally.

[0040] like Figure 3As shown, behind the three moving components 5, three peeling components 7 are also evenly arranged along the circumference of the inner wall of the clamping cavity 11, and the positions of the peeling components 7 and the moving components 5 on the circumference are staggered to avoid interference. Each peeling component 7 includes a fourth telescopic motor 71 fixed radially, and its telescopic rod is connected to a second electric wheel 73 through a second pressure sensor 72. The rotation axis of the second electric wheel 73 is parallel to the axis of the clamping cavity 11, so that it can generate a circumferential grinding force when it rotates.

[0041] The tool operates as follows: The operator holds handle 8 and first activates the first rotating motor 31 via control panel 9, causing the clamping member 2 to open. The clamping cavity 11 of the tool is then inserted into the end of the branch and moved to the starting position where girdling is required. Subsequently, the clamping member 2 is closed, causing the first electric wheels 53 of the three moving components 5 and the second electric wheels 73 of the three peeling components 7 to gently contact the surface of the branch. Next, the moving components 5 are activated, the first telescopic motor 51 extends, and based on feedback from the first pressure sensor 52, the first electric wheel 53 is pressed against the branch with a constant preset pressure and begins to rotate, providing the tool with the driving force to move forward.

[0042] As the tool moves forward, the operation proceeds automatically and sequentially: the first cutting component 4 at the front, under control, precisely inserts its blade and completes a circumferential cut; the second cutting component 6, following closely behind, extends its first blade 63 to make an axial incision in the bark; the circumferential and longitudinal cuts form a "U"-shaped incision that separates the bark. Next, the tool continues forward, and the peeling component 7 in the middle and rear activates. Based on feedback from the second pressure sensor 72, the fourth telescopic motor 71 applies appropriate pressure to the rotating second electric wheel 73, pressing it against the edge of the cut bark, using circumferential friction to rub and peel the bark from the wood. Throughout the process, the operator only needs to hold the tool steady and monitor various parameters through the control panel 9 to complete the circumferential peeling operation in one go with high quality. Once the required circumferential peeling length is reached, the cutting and peeling components 7 are reset, the clamping parts 2 are released, and the tool can be removed.

[0043] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
