Description

Technical Field

[0001] The utility model relates to the field of tree measurement, in particular to a tree measuring device for forestry. Background Art

[0002] In the current forest resource inventory and forestry survey research, the tree breast diameter is one of the most basic data. Traditional measuring tools are mainly girth rulers or calipers. The girth ruler requires the measurer to wrap both hands around the tree trunk, which is laborious to operate, while the caliper has a limited measuring range and is not suitable for trees with larger diameters.

[0003] After searching, Chinese patent publication number CN221666825U discloses a tree growth measuring device, which includes a first rotating seat and a second rotating seat. A measuring mechanism is provided on the top of the fixed rod. A sliding cavity is provided inside the measuring seat above the sliding groove. The internal rotation of the sliding cavity is connected to a gear, and the gear is meshed with a first rack and a second rack. The device can drive two measuring splints to be clamped on both sides of the trunk by turning the knob, so that the thickness of the trunk can be observed and recorded according to the scale line. The bolt is turned to fix the chuck with the claw, so that the position of the measuring splint is fixed, which is convenient for observing the value. The splint can be clamped and fixed from both sides of the trunk under the measuring mechanism, thereby ensuring stability when using the measuring mechanism and improving the accuracy of the data. However, since the cross-section of the tree is not a standard circle, multi-point measurement is required. The existing tree measuring device is inconvenient to use during multi-point measurement, and it is difficult to avoid the scab position, which affects the measurement accuracy.

Therefore, they cannot be understood as limitations on the present invention.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figure 1 — Figure 6As shown, a tree measuring device for forestry includes two symmetrical clamping rings 101, with a hinge shaft 102 provided between the clamping rings 101. The hinge shaft 102 is installed between the two clamping rings 101 so that the two clamping rings 101 can be unfolded and clamped on the periphery of the tree to form a complete circle. The end of the clamping ring 101 away from the hinge shaft 102 is connected to a docking plate 103 by a bolt. A mounting mechanism is installed at the bottom of the clamping ring 101, and an annular slide 105 is provided on the clamping ring 101. A moving mechanism is slidably provided on the clamping ring 101, and the moving mechanism includes two moving seats 301. The moving seats 301 are slidably connected in the annular slide 105 of the clamping ring 101. An arc rod 302 is connected to the side of the moving seat 301 by bolts. The moving seat 301 and the arc rod 302 together form an annular structure for keeping the positions of the moving seats 301 relative to each other when moving in the annular slide 105.

[0028] The top of the movable seat 301 is connected to the connecting seat 303 by bolts, and the connecting seat 303 is rotatably connected to the fixed shell 304. The fixed shell 304 is provided with a lifting mechanism, which includes a lifting rod 401, which is threadedly connected to the fixed shell 304, and the top of the lifting rod 401 is rotatably connected to the connecting block 402, and the top of the connecting block 402 is connected to the connecting rod 403 by bolts. The top of the connecting rod 403 is hinged with a top plate 404, and a measuring mechanism is installed on the top plate 404. The measuring mechanism includes a tape measure 501 and a clamping plate 502, which are respectively connected to the tops of the two top plates 404 by bolts. There are two clamping plates 502. During measurement, the end of the tape measure 501 is clamped between the two clamping plates 502, and the protruding part of the tape measure 501 fits on the tree bark between the two top plates 404 and forms a semicircle, and the protruding part is half of the circumference of the tree.

[0029] In this embodiment, the bottom of the measuring tape 501 is connected to a plurality of symmetrically arranged connecting plates 503 by bolts, and the opposite side of the connecting plates 503 is connected to a spherical support 504 by bolts. A ball 505 is rotatably installed in the spherical support 504. The arrangement of the ball 505 allows the ball 505 to roll on the surface of the tree when the movable base 301 rotates in the annular slide 105, thereby facilitating multi-point measurement when measuring the circumference data of the tree.

[0030] In this embodiment, one side of the connecting rod 403 is connected to a sleeve shaft 405 by a bolt, and the measuring mechanism includes an elastic belt 506. When measuring a tree, the elastic belt 506 is sleeved on the two sleeve shafts 405 to ensure that the ball 505 always fits the tree skin.

[0031] In this embodiment, the sleeve shaft 405 is arranged at the position of the symmetry axis of the connecting plate 503 and away from the spherical support 504. The arrangement of the sleeve shaft 405 allows the elastic band 506 to be tightened between the sleeve shafts 405, thereby pulling the two top plates 404 closer to each other, so that the ball 505 can better fit the surface of the tree.

[0032] In this embodiment, an axially arranged observation window 305 is provided on the side of the fixed shell 304, and a scale 306 is provided on the outer side of the fixed shell 304. The arrangement of the observation window 305 and the scale 306 enables the surveyor to keep the two top plates 404 at the same height position, thereby improving the accuracy of tree measurement.

[0033] In this embodiment, a mounting hole is provided on the docking plate 103, and a hand-tightening bolt 104 is detachably connected to the mounting hole. The clamping ring 101 is clamped on the tree, and the hand-tightening bolt 104 is screwed into the docking plate 103 to install the device on the side of the tree.

[0034] In this embodiment, the mounting mechanism includes a fixing plate 201 , a screw rod 202 is threadedly connected to the fixing plate 201 , and an anti-slip pad 203 is bonded to an opposite end of the screw rod 202 .

[0035] Working principle: When using the device, first unfold the two clamps 101, wrap the clamps 101 around the surface of the tree, screw the hand-tightening bolts 104 into the docking plate 103 to combine the two clamps 101 to form a complete circle, then rotate the two screws 202 so that the screws 202 push the anti-slip pad 203 against the side of the tree. After the installation is completed, hold the top plate 404 at the top, rotate the lifting rod 401, and cooperate with the observation window 305 and the scale 306 to raise the two lifting rods 401 to the same measurement height, and pay attention to avoid the scab position of the tree to avoid measurement errors. Then put the elastic band 506 of appropriate length on the two sleeve shafts 40 5, the two top plates 404 are brought close to each other, and the ball bearings 505 on both sides are attached to the tree bark. When measuring, the measuring tape 501 is pulled out, and the extended end of the measuring tape 501 moves along the tree bark to the position of the top plate 404 on the other side and is clamped between the clamping plates 502. The extended part of the measuring tape 501 is half of the circumference of the tree. The staff rotates the movable seat 301, and the movable seat 301 and the arc-shaped rod 302 rotate in the annular slide 105. During the rotation, the arc-shaped rod 302 pushes the other movable seat 301, so that the two movable seats 301 are always in relative position, so that multiple points of the tree can be measured. It is easy to use and improves measurement accuracy.
