A method for tapping pine trees, a tapping aid and a method for using the tapping aid

Abstract

The present application also provides a method for cutting the surface of a pine tree to collect resin, an auxiliary device for cutting the surface of a pine tree and a method for using the device. The method for cutting the surface of a pine tree to collect resin ensures normal growth of the pine tree by retaining a bark section between two cuts to form a nutrient zone with a width of 0.5-1 cm, which ensures normal upward transport of nutrients. The nutrient zone is arranged to keep the surface of the pine tree in a continuous state after cutting, which avoids a decrease in wind resistance due to a completely bare surface, thereby preventing the wind resistance of the pine tree from being too low. In addition, the nutrient zone can grow and widen on both sides as the pine tree grows, which further improves the wind resistance of the pine tree and prevents the pine tree from being broken. After a short period of time (2-3 years), the bark near the nutrient zone can completely cover the cut bark, thereby enabling the cutting operation to be performed again and improving the overall resin collection efficiency of the pine tree, thereby solving the problem of poor resin collection efficiency caused by the pine tree losing its resin collection value after years of operation in the prior art.

Description

Technical Field

[0001] This invention relates to the field of pine resin tapping technology, and in particular to a method for tapping resin from pine tree surfaces, a tapping auxiliary device, and the method of using the same. Background Technology

[0002] Pine resin is an important forestry resource. Typically, pine trees with a diameter at breast height (DBH) of 20cm or more are selected for resin tapping. A cutting tool is used to cut the bark on the pine trunk, allowing resin to flow out. A collection container is then installed at the lower end of the trunk to collect the resin – this is known as tapping. In practice, tapping is generally concentrated between May and October each year. Each eligible pine tree typically requires at least one round of tapping (e.g., tapping every 3-7 days, for approximately 60 days). This process eventually results in a large, non-healing patch of bark on the trunk. After years of tapping, the pine tree becomes unusable for resin tapping (if one side of the bark is cut, there's nowhere else to cut; cutting the other side would prevent nutrients from reaching the tree, hindering its growth). Ultimately, the resin tapping yields poor results. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a method for resin tapping of pine trees, which solves the problem that pine trees lose their resin tapping value after years of operation, resulting in poor resin tapping efficiency.

[0004] According to an embodiment of the present invention, a method for resin tapping of pine trees includes the following steps:

[0005] Make two diagonal cuts on the bark at the same height on the trunk, with the lower ends of the two cuts close together and some bark left to form a nutrient strip 0.5-1cm wide. During the process, place collection containers on the trunk below all the cuts to collect the resin.

[0006] Specifically, the requirements for the resin tapping target are the same as in existing technologies. After cutting, a vertical bark segment will be left between the two cuts. This bark segment (i.e., a 0.5-1cm wide nutrient strip) can allow nutrients from the lower end of the trunk to be transported upward normally. At the same time, over time, this bark segment will also grow laterally, thus increasing its width. After many years, resin tapping can be performed on the other side of the pine tree. The bark segment on this side can serve as a nutrient supply channel to ensure the normal growth of the pine tree, thereby improving the overall resin tapping efficiency of the pine tree.

[0007] Furthermore, after an interval of 3-7 days, continue to widen the incision downwards and repeat 8-20 times.

[0008] Furthermore, the bark adjacent to the lower edge of the cut is reinforced with a positioning device that passes through the bark and inserts 0.5-1 cm into the xylem.

[0009] According to an embodiment of the present invention, a cutting auxiliary device for cutting pine trees is also provided, which includes a clamping cylinder that surrounds the trunk, a pair of inclined frames at the same height on the clamping cylinder, and the lower ends of the two inclined frames being separated; the clamping cylinder also has two rows of several through holes that are parallel to the lower edges of the two inclined frames, and a positioning element is detachably provided in each of the through holes.

[0010] Furthermore, the clamping cylinder includes two opposing semi-circular plates, each of which is provided with a pair of connecting plates, and the two pairs of connecting plates are connected by bolts to form a circular clamping cylinder, and the two inclined frames are respectively provided on the two semi-circular plates.

[0011] Furthermore, it also includes a flow guide channel, one end of which is fixedly connected to connecting ears located on both sides and the other end extends obliquely downward. Each of the two connecting ears is provided with a connecting hole, and the two semi-arc plates are respectively threaded to the connecting holes by screws.

[0012] Furthermore, it also includes a collection container fixed to the lower end of the tree trunk, and the orthographic projection of the end of the guide channel opposite to the connecting ear is located inside the collection container.

[0013] Furthermore, the positioning element includes a connecting section that is threadedly connected to the perforated section and an insertion section that partially passes through the bark and inserts into the wood.

[0014] Furthermore, the portion of the insert segment that is inserted into the wood has a spike-like structure.

[0015] According to an embodiment of the present invention, a method for using the above-mentioned cutting auxiliary device is also provided, which includes the following steps: placing a clamping cylinder larger than the trunk diameter after encirclement on the trunk where the cutting surface needs to be cut, fixing the clamping cylinder on the trunk by a positioning component, and then using a cutter to cut from the upper edge of the inclined frame to form a cut. After completion, the guide channel and the collection container are installed respectively to start collecting rosin.

[0016] After the resin collection is completed, the diversion channel, collection container and clamping tube are disassembled, and the insertion section of the positioning piece is left on the trunk.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1) This method ensures that a vertical nutrient band is left on the pine tree after the cut (by leaving bark between the two cuts to form a nutrient band 0.5-1cm wide), which ensures that nutrients are transported normally from bottom to top, allowing the pine tree to grow normally.

[0019] 2) The setting of the nutrient strip ensures that the bark of the pine tree is in a continuous state after the cut surface, which can avoid the reduction of wind resistance due to one side being completely barkless. This ensures that the wind resistance of the pine tree is not too low. At the same time, as the pine tree grows, the nutrient strip can grow to both sides more quickly and widen, which can further improve the wind resistance of the pine tree and prevent it from being broken.

[0020] 3) After a relatively short period of time (2-3 years), the bark near the nutrient zone can completely cover the cut bark, thus enabling tapping operations to be carried out again, improving the overall resin tapping efficiency of pine trees and solving the problem that pine trees lose their resin tapping value after many years of operation in the existing technology, resulting in poor resin tapping efficiency.

[0028] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used 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.

[0030] like Figure 1 , 2 As shown, this embodiment provides a method for resin tapping of pine trees, which includes the following steps:

[0031] Select pine trees that meet the requirements as resin tapping targets. Make two diagonal cuts on the trunk 1 at the same height, with the lower ends of the two cuts close together and leaving some bark to form a nutrient band 0.5-1cm wide. The two cuts form a V-shape. During the process, set up collection containers 2 on the trunk 1 below all the cuts to collect the resin. The resin will flow down the cuts and then into the collection containers 2 below.

[0032] Specifically, the requirements for the resin tapping target are the same as in existing technologies. After cutting, a vertical bark segment will be left between the two cuts. This bark segment (i.e., a 0.5-1cm wide nutrient strip) can supply nutrients from the lower end of the trunk to be transported upward normally. At the same time, over time, this bark segment will also grow laterally, thus increasing its width. After many years, resin tapping can be performed on the other side of the pine tree. The bark segment on this side can serve as a nutrient supply channel to ensure the normal growth of the pine tree, thereby improving the overall resin tapping efficiency of the pine tree.

[0033] In a more detailed implementation plan, the width of the incision is further increased downwards every 3-7 days (i.e., another cut is made along the lower edge of the incision with a cutter) and this is repeated 8-20 times, depending on the specific circumstances, with the total time controlled at around 60 days.

[0034] In a more detailed implementation plan, the bark adjacent to the lower edge of the cut is reinforced with a positioning element 3. The positioning element 3 penetrates the bark and inserts into the xylem 0.5-1cm. This can fix the bark at the edge of the cut. At the same time, after a period of time after the cut, due to the large length of the cut, the bark will peel off from the xylem. The positioning element 3 can limit the peeling distance between the bark and the xylem, preventing excessive peeling. At the same time, the positioning element 3 can also stimulate the xylem to promote xylem growth in the corresponding position, thereby promoting the inclination of nutrients to that area, which is beneficial to the growth of the bark in that area in the following years. In particular, after years of experimental observation, the applicant has found that the bark at the lower edge of the cut and the bark in the middle can grow to cover most of the cut part in 1-2 years, and can completely cover it after nearly 2-3 years. This allows for a second round of resin tapping on that side to maximize the effect of pine resin tapping.

[0035] like Figure 1-5 As shown, in another embodiment, a cutting aid device for assisting pine trees in cutting is also provided, which includes a clamping cylinder 4 that wraps around the trunk 1. The clamping cylinder 4 has a pair of inclined frames 5 at the same height, with their lower ends separated. The clamping cylinder 4 also has two rows of perforations parallel to the lower edges of the two inclined frames 5. A positioning element 3 is detachably installed in each perforation. The positioning element 3 can position the clamping cylinder 4 to fix it to the trunk 1. Furthermore, it can also increase... Positioning rods 6 (such as screws) are located at the upper and lower ends of the clamping cylinder 4. The positioning rods 6 are driven into the bark, thereby increasing the positioning stability between the clamping cylinder 4 and the trunk 1. In particular, in this embodiment, the inclined frame 5 has a large width to accommodate multiple cutting operations in the same round of work. It is not necessary to adjust the position of the clamping cylinder 4 for each cut, but only to ensure that the lower edge of the cut is abutted against the lower edge of the inclined frame 5 during the last cut (this ensures that the positioning component 3 can play a normal positioning role and limit the degree of peeling between the bark and the wood).

[0036] In a more detailed implementation, the clamping cylinder 4 includes two opposing semi-circular plates 7, each of which is provided with a pair of connecting plates 14, and the two pairs of connecting plates 14 are connected by bolts 13 to form a circular clamping cylinder 4. The two inclined frames 5 are respectively provided on the two semi-circular plates 7, which can facilitate the disassembly and installation of the clamping cylinder 4.

[0037] In a further detailed implementation, to facilitate the collection of pine resin, the device also includes a guide channel 8. One end of the guide channel 8 is fixedly connected to connecting ears 9 located on both sides, and the other end extends obliquely downward. Each of the two connecting ears 9 is provided with a connecting hole 15, and the two semi-arc plates 7 are threadedly connected to the connecting holes 15 by screws 10. In particular, the end of the guide channel 8 with the connecting ears 9 is also arc-shaped, so that after installation, the upper end of the back side (i.e., the side opposite to the bottom of the channel) of the guide channel 8 can abut against the trunk 1. With the connection of the connecting ears 9, screws 10 and the two semi-arc plates 7, and the screws 10 also abut against the bark, the guide channel 8 can be stably fixed to the trunk 1. Furthermore, the device also includes a collection container 2 fixed to the lower end of the trunk 1, and the orthographic projection of the end of the guide channel 8 opposite to the connecting ears 9 is located in the collection container 2. The pine resin flows smoothly into the collection container 2 after passing through the guide channel 8.

[0038] In a more detailed implementation, the positioning element 3 includes a connecting section 11 connected to the perforated thread and an insertion section 12 that partially penetrates the bark and inserts into the wood. The portion of the insertion section 12 that inserts into the wood has a spike-like structure, and the length of the insertion section 12 is greater than that of the bark. After the insertion section 12 is inserted into the wood, it plays a fixing role and stimulates the growth of the wood. The spike structure can penetrate the bark and insert into the wood more smoothly, while also reducing the degree of damage to the wood. Furthermore, the insertion section 12 also has a portion located between the semi-arc plate 7 and the bark, so that the inner wall of the clamping cylinder 4 will not come into contact with the bark at this point. This allows the bark at the cut point to have space to peel off from the wood normally. The peeling is restricted by the positioning element 3. Appropriate peeling can also promote growth at this point, which is beneficial for healing and growth.

[0039] like Figure 1-5 As shown, in another embodiment, a method for using the cutting aid device in the above embodiments is also provided, which includes the following steps:

[0040] After enclosing the trunk, the clamping tube 4, which is larger than the diameter of the trunk 1, is placed on the area of ​​the trunk 1 that needs to be cut. The clamping tube 4 is fixed on the trunk 1 by the positioning piece 3. Then, the cutter is used to cut from the upper edge of the inclined frame 5 to form a cut. After completion, the guide channel 8 and the collection container 2 are installed respectively to start collecting pine resin.

[0041] After multiple cuts and resin collection, the guide channel 8, collection container 2, and clamping tube 4 are disassembled, and the insertion section 12 of the positioning piece 3 is left on the trunk 1. In particular, the insertion section 12 is pulled out during the following year's operation for reuse, and the bark belt positioned by the insertion section 12 is skipped (leaving 3-5cm) during the cutting operation and the cutting continues downward.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
