Description

Technical Field

[0001] This utility model belongs to the field of growth cone technology, specifically relating to a tree growth cone. Background Technology

[0002] Tree rings have a significant impact on climate, ecology, and history. They not only reflect climate information of a given year, such as sunlight, precipitation, and temperature, but also aid in environmental pollution research. By analyzing the metallic elements in tree rings over a specific period, the causes of pollution can be identified. Furthermore, they can contribute to historical research; for example, the age of some shipwrecks can be determined by analyzing the wood grain and tree rings to identify the tree species and the degree of corrosion. Therefore, in-depth research into tree rings is both necessary and indispensable.

[0003] In tree ring core sampling, a growth cone is typically used. The specific procedure is as follows: First, the cone is held perpendicular to the tree trunk surface. By rotating the handle, the growth cone is driven into the tree. Once it has penetrated beyond the trunk radius, rotation is stopped. Then, a core extractor is inserted from behind the cone. The cone is then reversed half or a full turn to break off the core. After breaking off the core, the core extractor can be carefully removed to obtain the sample. However, extracting the core using a core extractor is laborious, cumbersome, and inconvenient to operate.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide a tree growth cone that makes sampling more convenient and can speed up the sampling process.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A tree growth cone includes a sampling tube and a handle. A sampling cone head is formed at the front end of the sampling tube, and the inner diameter of the sampling cone head is smaller than the inner diameter of the sampling tube. A cutting assembly for cutting tree core is provided on the tube wall of the sampling tube. The cutting assembly includes at least two sets of cutting blades and a driving member for driving the cutting blades to move radially along the sampling tube. The driving member includes a driving plate and a driving head. A first receiving cavity for placing the cutting blades, a second receiving cavity for receiving the driving head, and a guide groove for the driving plate to move are formed on the tube wall of the sampling tube. The guide groove communicates with the second receiving cavity, and the second receiving cavity communicates with the first receiving cavity. The width of the second receiving cavity is smaller than the width of the first receiving cavity. A first guide slope that fits against the cutting blades is formed on one side of the driving head, and a second guide slope that cooperates with the first guide slope is formed on the cutting blades.

[0008] Furthermore, the cutting blades are arranged in two sets, symmetrically. One end of the drive plate extends beyond the end of the sampling tube, and the ends of the two drive plates are connected by a connecting ring. The connecting ring is coaxially arranged with the sampling tube, and the inner diameter of the connecting ring is greater than or equal to the inner diameter of the sampling tube. The symmetrical arrangement of the two sets of cutting blades allows for rapid cutting of the wood core.

[0009] Furthermore, the cutting blade has serrations at the end near the wood core. The serrations further cut the wood core.

[0010] Furthermore, the bottom of the cutting edge is provided with an elastic support member. The lower end of the elastic support member is fixedly connected to the bottom wall of the first receiving cavity, and the upper end of the elastic support member is slidably connected to the bottom of the cutting edge. The elastic support member includes an upper sleeve, a lower sleeve, and a spring. The spring is located inside the upper sleeve and the lower sleeve, and the upper sleeve is slidably fitted inside the lower sleeve. The lower sleeve is fixedly inserted into the bottom wall of the first receiving cavity. The top of the upper sleeve is provided with a sliding piece that slides in contact with the bottom of the cutting edge, and the bottom of the cutting edge has a limiting groove for the sliding piece to slide. The elastic support member provides a supporting force for the cutting edge, preventing it from tilting, and can also accommodate the axial and radial movement of the cutting edge.

[0011] Furthermore, the sampling tube and the handle are detachably connected. A mounting sleeve for installing the sampling tube is formed in the middle of the handle. The inner wall of the mounting sleeve is adapted to the inner wall of the sampling tube. A limiting groove is formed on the inner wall of the mounting sleeve, and the top end of the limiting groove penetrates the upper surface of the mounting sleeve. A limiting strip is formed on the outer wall of the sampling tube, which mates with the limiting groove. A limiting cap is also rotatably mounted on the mounting sleeve. A clearance hole for the sampling tube to pass through is formed in the middle of the limiting cap. The diameter of the clearance hole is equal to the outer diameter of the sampling tube. A clearance groove for the limiting strip to pass through is also formed on the limiting cap. This connection and assembly structure allows for quick assembly and disassembly of the sampling tube and the handle.

[0012] Furthermore, the handle is a hollow tube, and the sampling tube can be stored inside the handle. Storing the sampling tube inside the handle saves storage space and makes it easy to carry.

[0013] With the above structure, the tree growth cone of this utility model, compared with the prior art, has a cutting component set in the sampling tube. The cutting component can directly cut the wood core. Since the inner diameter of the sampling cone head is smaller than the inner diameter of the sampling tube, the diameter of the wood core entering the sampling tube is smaller than the inner diameter of the sampling tube. Thus, after obtaining the wood core sample, the wood core can be directly poured out from the tail of the sampling tube, which is more convenient and efficient in operation. In addition, when cutting the wood core, the sampling tube can be reversed. At this time, the serrations of the two cutting blades can cut the wood core, which can prevent the wood core sample from breaking in the middle and make the cut wood core sample more complete.

Detailed Implementation

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0026] like Figures 1-9As shown, this utility model relates to a tree growth cone, which includes a sampling tube 1 and a handle 2. The front end of the sampling tube 1 is formed with a sampling cone head 15, which is threaded to facilitate drilling into the tree trunk. The inner diameter of the sampling cone head 15 is smaller than the inner diameter of the sampling tube 1. The tube wall of the sampling tube 1 is provided with a cutting component 3 for cutting the tree core. The cutting component 3 includes at least two sets of cutting blades 31 and a driving member 32 for driving the cutting blades 31 to move along the radial direction of the sampling tube 1. The driving member 32 includes a driving plate 321 and a driving head 322. The tube wall of the sampling tube 1 is formed with a first receiving cavity 11 for placing the cutting blades 31, a second receiving cavity 12 for receiving the driving head 322, and a guide groove for the driving plate 321 to move. 13. The guide groove 13 is connected to the second receiving cavity 12, and the second receiving cavity 12 is connected to the first receiving cavity 11. The width of the second receiving cavity 12 is smaller than the width of the first receiving cavity 11. A first guide slope 3221 that fits against the cutting blade 31 is formed on one side of the driving head 322. A second guide slope 311 that cooperates with the first guide slope 3221 is formed on the cutting blade 31. In this embodiment, there are two sets of cutting blades 31, which are symmetrically arranged. One end of the driving plate 321 extends beyond the end of the sampling tube 1. The ends of the two driving plates 321 are connected by a connecting ring 323. The connecting ring 323 is coaxially arranged with the sampling tube 1, and the inner diameter of the connecting ring 323 is greater than or equal to the inner diameter of the sampling tube 1. By symmetrically arranging the two sets of cutting blades 31, the wood core can be cut quickly. In practical operation, when the sampling tube 1 is drilled to a certain depth, pressing the connecting ring 323 causes the two driving components 32 to move inward. With the cooperation of the first guide slope 3221 and the second guide slope 311, the cutting blade 31 can be driven to move towards the wood core, thereby cutting the wood core. In addition, in order to make the detection effect more accurate, the length of the cut wood core should be at least half of the trunk diameter. Therefore, a scale can be set on the outer wall of the sampling tube 1, with the starting point of the scale starting from the cutting blade 31. In this way, the length of the cut wood core can be accurately determined by observing the sampling tube 1.

[0027] In this embodiment, to facilitate cutting the wood core, prevent it from breaking in the middle, and create a smoother cut surface, a serration 312 is formed at the end of the cutting blade 31 near the wood core. During cutting, the connecting ring 323 is held down, and the sampling tube 1 is reversed, causing the cutting blade 31 to saw the wood core. However, because the front end of the sampling cone 15 is threaded, the sampling tube 1 continuously retracts outwards during reversal. At this point, the cutting blade 31 does not completely cut the wood core and remains stuck on it. The movement trajectory of the cutting blade 31 has two directions: it moves not only radially along the sampling tube 1 but also axially along the sampling tube 1. Therefore, an elastic support 4 is also provided at the bottom of the cutting edge 31. The lower end of the elastic support 4 is fixedly connected to the bottom wall of the first receiving cavity 11, and the upper end of the elastic support 4 is slidably connected to the bottom of the cutting edge 31. The elastic support 4 includes an upper sleeve 41, a lower sleeve 42, and a spring 43. The spring 43 is located inside the upper sleeve 41 and the lower sleeve 42, and the upper sleeve 41 is slidably sleeved inside the lower sleeve 42. The lower sleeve 42 is fixedly inserted into the bottom wall of the first receiving cavity 11. The top of the upper sleeve 41 is provided with a sliding piece 411 that slides in contact with the bottom of the cutting edge 31. The bottom of the cutting edge 31 forms a limiting groove 313 for the sliding piece 411 to slide. The elastic support 4 can provide a supporting force for the cutting edge 31, preventing the cutting edge 31 from tilting, and can also accommodate the axial and radial movement of the cutting edge 31.

[0028] In this embodiment, the sampling tube 1 and the handle 2 are detachably connected. A mounting sleeve 21 for mounting the sampling tube 1 is formed in the middle of the handle 2. The inner wall of the mounting sleeve 21 is adapted to the inner wall of the sampling tube 1. A limiting groove 211 is formed on the inner wall of the mounting sleeve 21. The top end of the limiting groove 211 penetrates the upper surface of the mounting sleeve 21. A limiting strip 14 that cooperates with the limiting groove 211 is formed on the outer wall of the sampling tube 1. Specifically, there are at least two limiting grooves 211. A limiting cap 22 is also rotatably mounted on the mounting sleeve 21. A clearance hole 221 for the sampling tube 1 to pass through is formed in the middle of the limiting cap 22. The diameter of the clearance hole 221 is equal to the outer diameter of the sampling tube 1. A clearance groove 222 for the limiting strip 14 to pass through is also formed on the limiting cap 22. In addition, an annular groove is provided on the outer wall of the mounting sleeve 21, and a rotating ring that cooperates with the annular groove is formed on the inner wall of the mounting cap. Anti-slip texture is also provided on the limiting cap 22. This connection assembly structure allows for quick assembly and disassembly of the sampling tube 1 and the handle 2. During installation, rotate the limiting cap 22 to align the limiting groove 211 with the clearance groove 222. Then, pass the sampling tube 1 through the clearance hole 221, aligning the limiting groove 211 with the limiting strip 14. Next, rotate the limiting cap 22 to displace the clearance groove 222 from the limiting strip 14. This completes the installation of the sampling tube 1 and the handle 2, preventing axial or radial movement between them. The entire installation process is very convenient.

[0029] In this embodiment, the handle 2 is a hollow tube, and the sampling tube 1 can be stored inside the handle 2. Storing the sampling tube 1 inside the handle 2 can save storage space and make it easy to carry.

[0030] The method of using this utility model is as follows: First, assemble the sampling tube 1 and the handle 2. Then, place the sampling tube 1 vertically against the tree trunk at a height of 1.3 meters. By rotating the handle 2, insert the sampling tube 1 into the tree trunk (until it reaches the specified depth). At this time, the tree core will also enter the sampling tube 1. Next, press down on the connecting ring 323 and reverse the sampling tube 1 to remove the sampling tube 1 from the tree trunk. At this time, the cutting blade 31 will cut the tree core and sever it. After the sampling tube 1 is completely removed, simply stand the sampling tube 1 upright with the tail of the sampling tube 1 facing downwards. Since the diameter of the tree core is smaller than the diameter of the sampling tube 1, the tree core can be poured out directly from the sampling tube 1.

[0031] The above provides a detailed description of a tree growth cone provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
