Description

Technical Field

[0001] This application relates to the field of forestry planting technology, and in particular to a lacquer tree cutting device for tapping lacquer trees. Background Technology

[0002] The lacquer tree originated in China, where it has been cultivated and utilized for over 4,000 years. It is an important special-purpose economic tree species in my country, primarily producing lacquer, which possesses excellent properties such as anti-corrosion, moisture resistance, acid resistance, high-temperature resistance, rapid drying and film formation, resistance to oxidation, and strong insulation. It is a natural coating. Lacquer wax can be extracted from the fruit peel, and oil can be pressed from the seeds; both lacquer wax and lacquer oil are important chemical raw materials. Raw lacquer is a milky liquid produced and stored in the sap channels of the lacquer tree. These sap channels are distributed throughout various organs of the lacquer tree, but are most abundant in the phloem of the main trunk. In cross-section, a mature tree typically has 3-6 sap channels per square millimeter. Lacquer can only be harvested after the sap channels have fully developed at a certain age. The age at which lacquer can be harvested varies greatly depending on the variety, site conditions, and management level; some trees can be harvested as early as 5-7 years old, while others cannot be harvested until 10-15 years old. However, the age at which lacquer trees should be harvested is mainly determined by the diameter of the trunk; it is more appropriate to start harvesting when the diameter at breast height is 15cm or more.

[0003] Lacquer tapping methods can be categorized into two types based on the shape of the cut: oblique cut and V-cut. The oblique cut involves making a 7-10cm long, 45° angled line at a chosen location. Subsequent taps are made by lightly cutting above and below the original cut, only reaching the phloem and avoiding damage to the wood. After repeated tapping, the cut forms a "painted eye" shape. The technical specification for lacquer tree cultivation (LY / T1894-2010) further specifies requirements for this "painted eye" shaped cut: cut width ≤ 4cm, and the distance between cuts ≥ 50cm.

[0004] However, the existing lacquer tapping knife has a relatively simple structure, consisting of a wooden handle and a cutting blade. When using it, workers select a good cutting position on the lacquer tree and make a 7-10cm cut. The width, length, and angle of the cut all depend on the worker's personal experience. This makes it difficult for workers to produce cuts that are close to the cutting parameters in the specifications, especially for new lacquer tapping workers. It is even more difficult to make qualified cuts using traditional lacquer tapping knives. Utility Model Content

[0005] This application provides a lacquer tree cutting device for tapping lacquer trees, which can effectively improve the accuracy of workers making cuts on lacquer trees.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] A lacquer tree cutting device for tapping lacquer trees includes an arc-shaped clamp plate with an inclined through hole.

[0008] The through hole is provided with two symmetrical side limiting plates on the side away from the concave surface of the arc-shaped clamp, and each side limiting plate is provided with a guide through hole along its length.

[0009] A cutting tool is provided between the two side limiting plates, and the cutting tool is movably connected to both side limiting plates. The cutting tool can move freely along the guide through hole on the side limiting plate.

[0010] One side of the arc-shaped clamp is mounted on the clamping assembly, which can fix the arc-shaped clamp to the lacquer tree to be cut.

[0011] Furthermore, the cutting tool includes a blade head with a door-hole shaped cross-section, and a cutting edge is provided at one end of the blade head near the through hole; a drive handle is fixedly installed on the side of the blade head opposite to its arc-shaped closed end.

[0012] Furthermore, a guide rod is fixedly connected to one of the opposite sidewalls in the width direction of the cutter head, and the two guide rods are respectively movably inserted into the guide through holes on the two side limiting plates, and the diameter of the guide rod is smaller than the width of the guide through hole.

[0013] Furthermore, the drive grip is L-shaped, the lower end of the vertical section of the drive grip is fixedly connected to the cutter head, and two stop bars are fixedly installed on the horizontal section of the drive grip near the upper end of the vertical section of the drive grip. The two stop bars are respectively located on opposite sides in the width direction of the vertical section of the drive grip, and the distance between the far ends of the two stop bars is greater than the distance between the far ends of the two guide bars.

[0014] Furthermore, a reinforcing rib is added at the connection between the vertical and horizontal sections of the drive grip.

[0015] Furthermore, the clamping assembly includes two clamp handles hinged together, and an extension rod is fixedly welded to the same end of each of the two clamp handles. One of the extension rods is fixedly connected to the arc-shaped clamping plate, and the other extension rod is fixedly connected to an auxiliary clamping plate, which is also an arc-shaped structure.

[0016] Furthermore, the width of the through hole is 4cm, the length of the through hole is 10cm, and the angle between the observation hole and the horizontal plane is 45°.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] When determining the location of the cut on the lacquer tree, the worker first secures the curved clamp to the surface of the lacquer tree. Then, the worker adjusts the curved clamp on the lacquer tree so that the position of the through hole on the curved clamp matches the determined cut location. Next, the worker can forcefully slide the cutting tool along the two side limiting plates outside the through hole, moving the cutting tool along the trajectory of the through hole. Guided by the through hole, the worker can use the cutting tool to cut a cut on the surface of the lacquer tree that is close to the length and width of the through hole. The through hole specifications of this application meet the requirements for cut size in the lacquer tree planting specifications. Therefore, the size of the lacquer tree cut made by the worker along the through hole will not deviate too much from the cut size required in the specifications. Compared with the traditional lacquer-cutting knife with a simple structure, it can effectively reduce the difficulty for workers to cut a qualified cut. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0025] like Figures 1-3 As shown, this application discloses a lacquer tree cutting device for tapping lacquer trees, which includes an arc-shaped clamping plate 1 and an inclined through hole 2 on the arc-shaped clamping plate 1.

[0026] Two symmetrical side limiting plates 3 are provided on the concave side away from the arc-shaped clamping plate 1. Each side limiting plate 3 has a guide through hole 4 along its length.

[0027] A cutting tool 5 is provided between the two side limiting plates 3, and the cutting tool 5 is movably connected to both side limiting plates 3. The cutting tool 5 can move freely along the guide through hole 4 on the side limiting plate 3.

[0028] One side of the arc-shaped clamp 1 is mounted on the clamping assembly 6, which can fix the arc-shaped clamp 1 to the lacquer tree to be cut.

[0029] In the above embodiments, the arc-shaped clamp 1 of this application, based on its own arc-shaped structure, can effectively improve its fit with the cylindrical lacquer tree when fixed to it by the clamping component 6. The specifications of the guide hole 4 on the arc-shaped clamp 1 match the cutting specifications required in the lacquer tree planting specifications. Thus, after the worker determines the position of the cutting on the lacquer tree, he can fasten the arc-shaped clamp 1 to the surface of the lacquer tree, and then adjust the arc-shaped clamp 1 so that the position of the through hole 2 on the arc-shaped clamp 1 coincides with the cutting position determined by the worker. Next, the worker can forcefully slide the cutting tool 5 along the two side limiting plates 3 outside the through hole 2, so that the cutting tool 5 moves along the trajectory of the through hole 2. During this process, the cutting tool 5 will simultaneously separate the bark from the surface of the lacquer tree. Guided by the through hole 2 and the guide hole 4 on the side limiting plate 3, the worker can use the cutting tool 5 to cut a slit on the surface of the lacquer tree that is close to the length and width of the through hole 2. The specifications of the through hole 2 in this application meet the requirements of the lacquer tree planting specifications for the size of the slit. Therefore, the size of the lacquer tree slit made by the worker along the through hole 2 will not deviate too much from the size of the slit required in the specifications. Compared with the traditional lacquer cutting knife with a simple structure, it can effectively reduce the difficulty for the worker to cut a qualified slit.

[0030] Furthermore, such as Figure 2 and Figure 3 As shown, the cutting tool 5 includes a cutter head 51 with a door-shaped cross-section. The cutter head 51 has a cutting edge at one end near the through hole 2. A drive handle 52 is fixedly installed on the side of the cutter head 51 opposite to its arc-shaped closed end.

[0031] In the above embodiments, the door-shaped blade 51 of the cutting tool 5 of this application allows it to quickly peel the bark from a certain area of ​​the tree surface using its cutting edge during movement. The peeled bark is automatically discharged through the through hole in the middle of the blade 51, similar to the effect of a conventional potato peeler. The drive handle 52 connected to the closed end of the blade 51 facilitates the worker's hand to exert force to move the blade 51 along a designated route. The amount of force can control the depth to which the cutting edge of the blade 51 cuts into the tree bark.

[0032] Furthermore, such as Figure 2 and Figure 3 As shown, a guide rod 7 is fixedly connected to one of the opposite sidewalls in the width direction of the cutter head 51. The two guide rods 7 are respectively movably inserted into the guide through holes 4 on the two side limiting plates 3, and the diameter of the guide rod 7 is smaller than the width of the guide through hole 4.

[0033] In the above embodiments, the cutting head 51 of this application is movably mounted in the guide holes 4 on the two side limiting plates 3 via the guide rod 7. This allows the guide holes 4 to provide guidance when the worker moves the cutting head 51 along the through hole 2. Simultaneously, an end block can be added to the end of the guide rod 7 to limit the position of the cutting head 51, preventing the cutting tool 5 from separating from the arc-shaped clamping plate 1 during storage or movement. The diameter of the guide rod 7 in this application is set smaller than the width of the guide holes 4, allowing the cutting head 51 to deflect slightly when the worker moves it along the through hole 2 to adapt to the real-time changes in the spiral side limiting plate 3.

[0034] Furthermore, such as Figure 2 and Figure 3 As shown, the drive handle 52 is L-shaped. The lower end of the vertical section of the drive handle 52 is fixedly connected to the cutter head 51. Two stop rods 8 are fixedly installed on the side of the horizontal section of the drive handle 52 near the upper end of the vertical section. The two stop rods 8 are located on opposite sides of the width direction of the vertical section of the drive handle 52. The distance between the far ends of the two stop rods 8 is greater than the distance between the far ends of the two guide rods 7.

[0035] In the above embodiments, while the drive handle 52 moves the blade 51, the worker can also use the guide rod 7 as a fulcrum to provide downward pressure to the blade 51 through the drive handle 52. This effect is similar to the lever principle, facilitating easy cutting of the lacquer tree bark by the blade 51. The drive handle 52 is L-shaped, and its horizontal section, via the stop bar 8, is always positioned on the side of the side limiting plate 3 away from the arc-shaped clamping plate 1. This allows the worker to quickly pick up the drive handle 52 when cutting. The distance between the far ends of the two stop bars 8 is greater than the distance between the far ends of the two guide rods 7, preventing the drive handle 52 and the stop bars 8 from getting stuck between the two side limiting plates 3, making it inconvenient for the worker to retrieve the drive handle 52.

[0036] Furthermore, such as Figure 2 and Figure 3 As shown, a reinforcing rib 9 is added at the connection between the vertical and horizontal sections of the drive grip 52.

[0037] In the above embodiments, by adding reinforcing ribs 9 at the connection between the vertical and horizontal sections of the drive handle 52, the overall strength of the cutting tool 5 can be improved and the risk of deformation during use can be reduced.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, the clamping assembly 6 includes two clamp handles 61 that are hinged together. An extension rod 62 is fixedly welded to the same end of each clamp handle 61. One extension rod 62 is fixedly connected to the arc-shaped clamping plate 1, and the other extension rod 62 is fixedly connected to the auxiliary clamping plate 63, which is also an arc-shaped structure.

[0039] In the above embodiments, the clamping component 6 of this application is configured in the manner described above to form a pliers-like structure. When the worker cuts along the surface of the lacquer tree, the stability of the arc-shaped clamp 1 is crucial. In this application, the arc-shaped clamp 1 is fixedly installed on the extension rod 62 at the end of one of the clamp handles 61, and an auxiliary clamp 63 corresponding to the arc-shaped clamp 1 is fixedly installed on the extension rod 62 at the end of the other clamp handle 61. In this way, when the worker needs to fix the arc-shaped clamp 1, he only needs to squeeze the two clamp handles 61 with one hand to clamp the arc-shaped clamp 1 and the auxiliary clamp 63 at the trunk of the lacquer tree, thereby achieving the effect of fixing the arc-shaped clamp 1.

[0040] Furthermore, the width of the through hole 2 is 4cm, the length of the through hole 2 is 10cm, and the angle between the through hole 2 and the horizontal plane is 45°.

[0041] In the above embodiments, the through hole 2 of this application is set according to the above specifications. In this way, when the worker uses the cutter head 51 to make a cut along the through hole 2, it can be ensured that the cut size meets the requirements of the lacquer tree planting specifications that the length is not greater than 10cm, the width is not greater than 4cm and the tilt angle is 45°.

[0042] The implementation principle of this embodiment is as follows: When the location for the cut on the lacquer tree is determined, the worker can hold the pliers handle 61 and spread the auxiliary clamping plate 63 and the arc-shaped clamping plate 1. The worker moves the entire device so that the trunk of the lacquer tree at the cut location is behind the auxiliary clamping plate 63 and the arc-shaped clamping plate 1. The worker then uses one hand to squeeze the two pliers handles 61 until the auxiliary clamping plate 63 and the arc-shaped clamping plate 1 clamp the lacquer tree trunk. Next, the worker can use the other hand to pick up the drive handle 52 and cut the lacquer tree bark along the through hole 2 with the blade 51. The through hole 2 of this application meets the requirements for cut size in the lacquer tree planting specifications. Therefore, the size of the lacquer tree cut made by the worker along the through hole 2 will not deviate too much from the cut size required in the specifications. Compared with the use of traditional lacquer-cutting knives with a simple structure, it can effectively reduce the difficulty for workers to cut a qualified cut. Furthermore, it can effectively reduce the learning curve for beginners to cut a qualified lacquer tree cut.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
