DETAILED DESCRIPTION
[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0018] like Figures 1 - 7As shown in the figure, a forestry survey tree ring detection device according to the present invention includes a bottom plate 1. One side of the top end of the bottom plate 1 is fixedly connected with a placement table 11. Fixing screws 15 are threadedly connected through both ends of the bottom plate 1 near one side of the placement table 11. In the middle of the lower end of the outer wall of one side of the placement table 11, a first electric telescopic rod 2 is fixedly connected. One end of the first electric telescopic rod 2 is provided with a moving assembly 21. The top end of the moving assembly 21 is fixedly connected with a second electric telescopic rod 22. The top end of the second electric telescopic rod 22 is fixedly connected with a lifting plate 23 arranged in an arc shape. An arc-shaped groove 201 is opened at the upper end of the arc-shaped side of the lifting plate 23. In the middle of the inner top end of the arc-shaped groove 201, a first rotating ball 25 is ball-joint connected. The top end of the first rotating ball 25 is fixedly connected with a hollow adjusting ring 24 with one end closed. One side outer wall of the hollow adjusting ring 24 is fixedly connected with an adapter box 3. A through hole 204 is penetrated and opened on the outer side wall of the hollow adjusting ring 24 near the inside of the adapter box 3. The top end of the adapter box 3 is fixedly connected with a motor 31. The output end of the motor 31 is fixedly connected with a winding roller 32. A measuring soft tape 33 is fixedly wound in the winding groove of the winding roller 32. And the measuring soft tape 33 passes through the through hole 204 and passes through the hollow adjusting ring 24 and extends to the outside. The top of one end of the measuring soft tape 33 is fixedly connected with a limiting cylinder 34; A bracket 4 arranged in an L shape is fixedly connected to the top end of the lifting plate 23 near one side of the hollow adjusting ring 24. Conical rotating grooves 401 are opened at the edges of the top and bottom ends of the bracket 4. A second rotating ball 42 is ball-joint connected between the two rotating grooves 401. The top and bottom ends of the second rotating ball 42 are fixedly connected with a shifting rod 41 respectively. And the two shifting rods 41 extend to the upper and lower ends of the bracket 4 respectively. Threaded rods 43 are threadedly connected through the middle parts of the two shifting rods 41 and the second rotating ball 42. The bottom end of the threaded rod 43 is fixedly connected with a limiting block 44. A conical groove 205 is opened at the top end of the hollow adjusting ring 24 near the lower end of the bracket 4. A slot 206 is opened at the inner bottom end of the conical groove 205. A plurality of adjusting grooves 207 are opened at the inclined ends of the conical groove 205.
[0019] Specifically, one end of the bottom plate 1 is arranged in a V-shaped opening. A growth cone 16 is installed at the lower end of the outer wall of the first electric telescopic rod 2. The V-shaped bottom plate 1 can be inserted into the outer end of the tree trunk. First, measure the breast diameter or ground diameter. After determining the breast diameter or root diameter, calculate the radius, and drill into the heartwood at the radius of the breast diameter or root diameter of the ancient and famous trees with the growth cone 16.
[0020] Specifically, handrails 12 are fixedly connected to both ends of the other outer wall of the placement table 11. A roller assembly 13 is arranged on one side of the bottom end of the bottom plate 1. Two support rods 14 are arranged on the other side of the bottom end of the bottom plate 1. Push the handrail 12 to drive the bottom plate 1 to move through the roller assembly 13.
[0021] Specifically, limiting grooves 202 are provided at the top of the hollow adjusting ring 24 near the edge of one side close to the connection box 3, and the limiting cylinder 34 is clamped in the limiting groove 202. A scale groove 203 is penetrated and opened at the edge of the top of the hollow adjusting ring 24 near one side of the limiting groove 202, and the inner diameter of the scale groove 203 is adapted to the outer diameter of the measuring flexible ruler 33. When the limiting cylinder 34 is clamped in the limiting groove 202, the measuring flexible ruler 33 can be stretched accordingly.
[0022] Specifically, a spirit level 26 is fixedly connected to the outer wall of the hollow adjusting ring 24 on the side far from the connection box 3, and the spirit level 26 is visually observed to check whether the hollow adjusting ring 24 is in a horizontal position.
[0023] Specifically, the limiting block 44 is clamped in the slot 206, and when the limiting block 44 is inserted into the slot 206, the hollow adjusting ring 24 can be in a fixed state.
[0024] Specifically, a handle 45 is fixedly connected to the top of the threaded rod 43, and rotating the handle 45 drives the threaded rod 43 to rotate.
[0025] When in use, first push the handrail 12 to drive the bottom plate 1 to move through the roller assembly 13. When the V-shaped end of the bottom plate 1 is stuck into the outer wall of the trunk, the fixing screws 15 at both ends are respectively rotated to fix it to the ground, and then the first electric telescopic rod 2 is started to drive the moving assembly 21 to move toward the side of the trunk. At this time, the moving assembly 21 will drive the second electric telescopic rod 22 to move synchronously, so that the lifting plate 23 drives the hollow adjustment ring 24 to approach the outer end of the trunk, and then the second electric telescopic rod 22 is started to drive the lifting plate 23 to move upward to the height of the trunk diameter at breast height and stop, and then observe whether the level meter 26 is in a horizontal position. When the level 26 is not in the horizontal position, the handle 45 is turned forward to drive the threaded rod 43 upward to disengage the limit block 44 from the slot 206. Then the staff will drive the toggle rod 41 along the rotating slot 401 through the second rotating ball 42 for adjustment. At this time, the threaded rod 43 will point to the side with a higher inclination. The handle 45 is reversed to drive the threaded rod 43 to rotate downward. At this time, the limit block 44 will be inserted into any one of the adjustment slots 207 with a higher inclination. Continuous rotation can be performed for horizontal adjustment. Then the first electric telescopic rod 2 is started again to drive the moving assembly 21 to continue to move toward the tree. The staff then clamps the limiting tube 34 in the limiting groove 202, and then starts the motor 31 to drive the winding roller 32 to rotate. At this time, the measuring tape 33 will be rolled up and close to the tree trunk. Then, the scale on the surface of the measuring tape 33 can be observed, and the diameter at breast height of the tree trunk can be measured. When the growth cone 16 is rotated clockwise to the center point of the root diameter or breast height of the ancient tree (the radius of the measured root diameter or breast height of the ancient tree is less than the length of the growth cone 16), or when the root diameter or the diameter at breast height of the ancient tree is less than the radius of the growth cone 16, the staff will stop the limiting tube 34 in the limiting groove 202, and then start the motor 31 to drive the winding roller 32 to rotate. At this time, the measuring tape 33 will be rolled up and close to the tree trunk. Then, the scale on the surface of the measuring tape 33 can be observed, and the diameter at breast height of the tree trunk can be measured. When the radius of the root diameter or the breast diameter is greater than the length of the growth cone 16, rotate the growth cone 16 counterclockwise to slowly withdraw from the drill hole, and measure the total length of the drilled annual ring wood core. If the radius of the root diameter or the breast diameter is greater than the length of the growth cone 16, the length of the radial wood core is calculated based on the length of the wood core drilled by the growth cone 16. The drilled wood core is placed under a microscope, and several sections of tree annual ring wood cores are randomly taken with tweezers. The annual ring width is measured with a vernier caliper. The average tree annual ring width is calculated based on the widths of multiple annual rings, and then the total length of the annual ring wood core is divided by the average annual ring width, and the age of ancient trees and famous trees can be calculated and compared to obtain similar tree age rings.
