Description

Technical Field

[0001] The invention relates to the technical field of tree characteristic analysis, in particular to a fixed vertical hand-cranked tree core sampling device. Background Art

[0002] Trees are composed of bark, cambium, xylem, and pith. The core is the pith, the center of the annual rings. The core is relatively hard and easy to cut. To measure tree growth, core sampling is required. Drilling is the common method for sampling trees. By drilling core samples, the growth rate, age, growth firmness, nutrient transport, and other related subjects can be analyzed and determined without disrupting the normal growth of the tree. This sampling method is achieved using a tree growth cone. However, existing tree growth cones have certain drawbacks when performing core sampling, as follows:

[0003] 1. Because the experiment requires that the sampling process requires vertical drilling into the tree, the existing equipment cannot guarantee vertical drilling.

[0004] 2. The existing equipment does not have a reasonable labor-saving structure, which requires a large amount of manpower to twist in order to complete the sampling work.

[0005] 3. The samples taken out by the existing equipment are broken due to the slow drilling speed, and the integrity of the samples cannot be guaranteed. Summary of the Invention

[0024] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0025] Example 1

[0026] like Figure 1-3The present invention shows a fixed vertical hand-cranked tree core sampling device, comprising a drilling mechanism 1 and a detachable fixing device 2 mounted on a tree trunk. The drilling mechanism 1 comprises a bracket 11 fixed on the drilling mechanism 1, a sleeve 12 fixed on the bracket 11, and when the fixing device 2 is mounted on the tree trunk, the sleeve 12 and the tree trunk are perpendicular to each other, a worm 13 is screwed into the sleeve 11, and avoidance holes are opened on the fixing device 2 and the bracket 11, and the two avoidance holes and the center of the sleeve 11 are The axes are all located on the same straight line, the diameter of the avoidance hole is larger than the rod diameter of the worm 13, an assembly frame 14 is fixed on the sleeve 11, and a turbine 15 that meshes with the worm 13 can be rotatably mounted on the assembly frame 14, and an avoidance opening 13 for the turbine 15 and the worm 13 to mesh is opened on the sleeve 11, and a rotating handle 16 is provided on the turbine 15. A sampling drill bit 17 is detachably mounted on the end of the worm 13 close to the tree trunk, and the sampling drill bit 17 has a sampling cavity inside. The end is provided with sampling serrations. During implementation, the turbine 15 is driven to rotate by turning the handle 16. The sleeve 12 is used to assemble the worm 13 on one hand, and on the other hand, it serves to limit the moving direction of the worm 13. When the turbine 15 rotates, the worm 13 is driven to rotate closer to or away from the tree trunk, thereby driving the sampling drill bit 17 to move closer to or away from the tree trunk. When sampling is needed, the rotation direction of the turbine 15 is controlled by turning the handle 16 so that the sampling drill bit 17 rotates close to the tree trunk, thereby realizing sampling of the tree core. During the entire sampling process, the sampling serrations on the sampling drill bit 17 cut the tree trunk, thereby accelerating the sampling process to ensure the integrity of the sample. After the sampling is completed, the turbine 15 is controlled to rotate in the opposite direction by turning the handle 16. At this time, the sampling drill bit 17 rotates away from the tree trunk. When the sampling drill bit 17 is away from the tree trunk, it is removed from the worm 13, and the tree core is taken out of the sampling cavity of the sampling drill bit 17.

[0027] The structure of the turbine 15 is as follows: Figure 4 As shown, the turbine 15 has a center hole 151, in which a driving wheel 152 is arranged. The inner wall of the center hole 151 is provided with driven teeth. The driving wheel 152 is meshed with a plurality of transmission wheels 153 meshing with the driven teeth. The driving wheel 152 and the plurality of transmission wheels 153 are all rotatably connected to the assembly frame 14. The rotating handle 15 is fixed on the driving wheel 152. The turbine 15 is rotated by the driving wheel 152 driving the plurality of transmission wheels 153. The entire sampling process utilizes a small gear to drive the larger turbine to rotate and drive the worm 13 to drive the sampling drill bit to rotate and move. The operation mode with a small gear ratio achieves a labor-saving effect, indirectly ensuring the sampling speed of the tree core, and thus ensuring the integrity of the sample.

[0028] Example 2

[0029] On the basis of the above embodiments, further Figure 1-2As shown, the fixing device 2 includes a regular hexagonal frame formed by six interconnected connecting rods 21. The regular hexagonal frame is divided into two fixing frames 22 at one of the connecting nodes. One set of adjacent ends of the two fixing frames 22 is hinged, and the other set of adjacent ends is detachably connected by a connecting member 23. The connecting member 23 can be a latch mechanism or a locking device. Three tightening adjustment members 24 are evenly arranged on the two fixing frames 22. When the three tightening adjustment members 24 are simultaneously pressed against the tree trunk to achieve fixation, the entire fixing process adopts a three-point movable fixing method, which can adapt to different tree sizes.

[0030] In some embodiments, the tightening adjustment member 24 adopts a telescopic mechanism. In this embodiment, the tightening adjustment member 24 includes a fixing rod 241, which is provided with an adjustment slot 242, and the adjustment slot 242 is movably mounted on the connecting rod 21. The fixing rod 241 is provided with a positioning slot 243 that intersects with the adjustment slot 242 in a "cross" shape in space, and the positioning slot 243 and the adjusting slot 242 are equal in length, and the length directions are parallel to each other. The connecting rod 21 is provided with a locking hole that cooperates with the positioning slot 243. When the position of the fixing rod 241 on the connecting rod 21 is determined, the fixing rod 221 is fixed by a bolt 244 that passes through the locking hole and the positioning slot 243 at the same time, thereby achieving fixation on the tree trunk.

[0031] Preferably, a roller 245 is provided at one end of the fixing rod 241 for resting against the tree trunk, and the roller 245 rolls along the circumferential side direction of the tree trunk. When the fixing device 2 is fixed to the tree trunk, the characteristic that the roller 245 can still roll along the circumferential side direction of the tree trunk is utilized so that the direction of the drilling mechanism 1 on the fixing device 2 can be adjusted, which is more convenient to use.

[0032] Example 3

[0033] As a preferred solution of the above embodiment, Figure 1 As shown, a tightening plate 3 is provided at one end of the sleeve 11 away from the tree trunk. When the user needs to drive the rotating handle 16 to rotate, the user leans against the tightening plate 3 to drive the rotating handle 16, thereby facilitating the user to exert force. Preferably, the tightening plate 3 is in the shape of an arc-shaped plate, which is more consistent with the shape of the human body. Furthermore, a threaded rod 4 is provided on the side of the arc-shaped plate away from the human body, and the threaded rod 4 is screwed to the sleeve 11, so that the distance between the arc-shaped plate and the rotating handle 16 can be adjusted according to the user's physique size.

[0034] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
