Description

Technical Field

[0001] The invention relates to the technical field of vegetation sampling, in particular to a vegetation sampling device for forestry surveying. Background Art

[0002] Vegetation sampling is an important part of forestry survey and ecological research. By collecting samples of plant leaves, branches, etc., it can provide a scientific basis for vegetation health assessment, species distribution research and environmental monitoring. However, the commonly used vegetation sampling devices are mostly based on single sampling, with low operating efficiency, and are prone to damage or contamination of samples during the sampling process, affecting the subsequent analysis results; In addition, most traditional sampling devices use cutting or direct clamping methods. Although they can meet some needs, they have certain limitations when facing scenarios with high requirements for leaf integrity. Therefore, designing a device that can perform multiple continuous samplings and achieve precise bite sampling of vegetation leaves can not only improve sampling efficiency but also effectively protect sample integrity. It is one of the important directions for improving current vegetation sampling equipment.

[0003] A Chinese patent (publication number CN116674853A) discloses a vegetation sampling device for forestry surveying, including a storage component for storing samples and a sampling component. The storage component includes a box, a sample storage box is arranged inside the box, an equipment box is connected to the top of the box, the sampling component is located in the equipment box, and a cushion is arranged on the top surface of the equipment box. The beneficial effect is that the device stores the equipment required for sampling in a box, and the sampling personnel only need to carry one box, and the box can be used as a stool during sampling, which can avoid the sampling personnel squatting on the ground for a long time for sampling, thereby reducing the work intensity of vegetation sampling, and also can avoid the problem of inconvenience of carrying more sampling equipment, thereby solving the technical problems existing in the prior art.

[0004] According to the above scheme, when in use, the above scheme only stores the leaves of the vegetation, and can store more plant samples. It is large in size and capacity and is not easy to carry. However, when collecting plant samples, it is still necessary for staff to collect them manually, which has limitations. In order to solve the problem that it is large in size and capacity and is not easy to carry and that it is still necessary for staff to collect them manually when collecting plant samples, we propose a vegetation sampling device for forestry surveying.

See also Figure 3-4 The storage mechanism 201 includes a fixed rectangular tube 25, the upper end of which is rotatably connected to a rotating plate 16 with a reset function through a rotating shaft. The rotating plate 16 can be rotated to sample the leaf samples inside the fixed rectangular tube 25.

Since each group of bite teeth 26 is sawtooth-shaped, when the leaves of the vegetation are bitten, they can be effectively fixed and the friction force can also be enhanced; The inner wall of the fixed rectangular tube 25 is rotatably connected to the first recovery wheel 18 with a reset function, and a first reset torsion spring is fixedly connected between the first recovery wheel 18 and the inner wall of the fixed rectangular tube 25. The outer wall of the first recovery wheel 18 is wound with a first pull rope 17, and the first pull rope 17 is made of nylon.

The output end of the first pull rope 17 is fixedly connected to the outer wall of the abutment arm 19, and the bottom of the abutment arm 19 is fixedly connected with a connecting block 21; See also Figure 5 , Figure 6 , Figure 8 , Fig. 9 , the upper end of the telescopic plate 5 is fixedly and slidably connected to the moving circular sleeve 20 with a reset function. Specifically, the upper end of the telescopic plate 5 is fixedly connected to the telescopic moving tube 27. The moving circular sleeve 20 slides on the outer wall of the telescopic moving tube 27. When the moving circular sleeve 20 slides on the outer wall of the telescopic moving tube 27, the telescopic moving tube 27 can limit the moving circular sleeve 20 and also has a guiding function, thereby improving the stability of the moving circular sleeve 20 when moving. The outer wall of the telescopic moving tube 27 and the inner wall of the moving circular sleeve 20 are both coated with lubricating oil. The lubricating oil can effectively reduce the friction between the moving circular sleeve 20 and the telescopic moving tube 27, and effectively extend the service life of the telescopic moving tube 27 and the moving circular sleeve 20. The moving circular sleeve 20 is fixedly connected to the telescopic plate 5 through a second elastic telescopic tube 40. The second elastic telescopic tube 40 can quickly reset the moving circular sleeve 20. There is a gap between the outer wall of the moving circular sleeve 20 and the connecting block 21. The rotating circular plate 2 A connecting plate is fixedly connected between 2 and the mounting sleeve box 2, a driving motor 30 is fixedly installed on the upper end of the connecting plate, a second recovery wheel 29 is fixedly connected to the output end of the driving motor 30, a third connecting rope 41 is wound around the outer wall of the second recovery wheel 29, a connecting ball 35 is fixedly connected to the third connecting rope 41 from the right end, a first elastic telescopic tube 37 is fixedly connected to the end of the connecting ball 35 away from the third connecting rope 41, the first elastic telescopic tube 37 is fixedly connected to the movable circular sleeve 20 through the second pull rope 28, the connecting ball 35 is spherical, a limiting block is fixedly connected to the inside of the fixed rectangular tube 25, the outer wall of the limiting block abuts against the outer wall of one group of sampling boxes 24, when the first recovery wheel 18 resets and pulls the abutting arm 19 and the sampling box 24 through the first pull rope 17, in order to prevent the sampling box 24 from being completely reset to the inner wall of the fixed rectangular tube 25, the limiting block can effectively prevent the sampling box 24 from completely moving to the innermost end of the inner wall of the fixed rectangular tube 25.

[0031] See also Figure 8The sampling mechanism 101 includes two sets of matching rotating boxes 32, and the two sets of matching rotating boxes 32 are rotatably connected to the outer wall of the telescopic sampling tube 3 through a rotating shaft. The two sets of matching rotating boxes 32 are closed to each other, and the opposite ends of the two sets of matching rotating boxes 32 are fixedly connected with cutting blades. The cutting blades are made of metal and have good sharpness. When the two sets of cutting blades are closed, the vegetation leaves can be effectively cut, making sampling easier. The outer wall of each set of matching rotating boxes 32 is fixedly connected with two sets of meshing gears 31. The two sets of meshing gears 31 are symmetrically distributed on the outer wall of the matching rotating boxes 32. Every two sets of corresponding meshing gears 31 are meshed with each other. The outer wall of the telescopic sampling tube 3 is also fixedly connected with a first telescopic air pipe 36, and the output end of the first telescopic air pipe 36 is fixedly connected with a rack 3 4, the upper end of the rack 34 is meshed with a corresponding set of meshing gears 31, and the second telescopic air tube 42 is fixedly connected to one end of the installation sleeve 2 close to the telescopic sampling tube 3, and the outer wall of the third connecting rope 41 is passed through the first telescopic air tube 36, the first telescopic air tube 36 is fixedly connected with the second telescopic air tube 42 through a pipeline, and the first telescopic air tube 36 is adapted to the connecting ball 35. A clamping column groove 33 is opened on the inner wall of each group of matching rotating boxes 32, and the aperture of the clamping column groove 33 is smaller than the diameter of the abutting cylinder 23. When the abutting cylinder 23 on the outer wall of the sampling box 24 is clamped with the inner wall of the corresponding clamping column groove 33, when the two groups of matching rotating boxes 32 rotate, the two groups of matching rotating boxes 32 can drive the corresponding two groups of sampling boxes 24 to open and merge through the clamping column groove 33 and the abutting cylinder 23.

[0032] The working principle of the present invention is: When the present invention is used, the staff holds the casing 1, and the casing 1 drives the telescopic sampling tube 3 and the two sets of matching rotating boxes 32 to move through the casing 1, and moves the two sets of matching rotating boxes 32 to the side of the blades that need to be sampled. At this time, the driving motor 30 is started, and the driving motor 30 drives the second recovery wheel 29 to rotate. The second recovery wheel 29 pulls the bite teeth 26 through the second pull rope 28 and the third connecting rope 41. When the bite teeth 26 move, they will pull the second elastic telescopic tube 40. At this time, the second elastic telescopic tube 40 accumulates force, and when the moving circular sleeve 20 moves, it will also drive the abutment arm 19 to move through the connecting block 21, and the abutment arm 1 9 drives the two groups of sampling boxes 24 to move, and the abutting arm 19 moves in the inner wall of the sliding groove 38 at the bottom end of the inner wall of the telescopic sampling tube 3 through the fixed rectangular tube 25. When the sampling box 24 moves to the inner wall of the matching rotating box 32, the abutting cylinder 23 of the outer wall of the sampling box 24 merges, and the second pull rope 28 continues to be pulled. When the second pull rope 28 continues to be pulled, when the connecting ball 35 abuts against the first telescopic air tube 36, the first elastic telescopic tube 37 is stretched, and the connecting ball 35 squeezes the second telescopic air tube 42, and the gas inside the second telescopic air tube 42 enters the first telescopic air tube 36. When the first telescopic air tube 36 is extended, the first telescopic air tube 36 drives the rack 34 to move, and the rack 34 meshes and rotates one set of meshing gears 31, and the two sets of meshing gears 31 rotate. At this time, the two sets of matching rotating boxes 32 are opened, and the two sets of matching rotating boxes 32 can drive the two sets of sampling boxes 24 to open. At this time, the driving motor 30 drives the second recovery wheel 29 to reset and rotate. At this time, the first recovery wheel 18 will reset and rotate, and the first recovery wheel 18 will abut the abutment arm 19 through the first pull rope 17. Pull back, the abutment arm 19 drives the two groups of sampling boxes 24 to reset and move, the second elastic telescopic tube 40 drives the moving circular sleeve 20 to reset and move, when the third connecting rope 41 drives the connecting ball 35 and the first elastic telescopic tube 37 to reset, the connecting ball 35 is separated from the abutment with the second telescopic air pipe 42, and the rack 34 is reset at this time, the two groups of matching rotating boxes 32 are closed with each other, and the abutment arm 19 drives the two groups of sampling boxes 24 to reset and move, when the sampling boxes 24 are abutted with the limit block, the sampling of vegetation leaves can be completed at this time; When sampling is needed, it is only necessary to start the electric telescopic rod 6 to drive the rotating abutment block 7 to move downward. When the rotating abutment block 7 abuts against the outer wall of the corresponding abutting curved strip 8, the rotating abutment block 7 will drive the rotating mounting plate 9 to rotate through the abutting curved strip 8, and the rotating mounting plate 9 will drive all the fixed rectangular tubes 25 to rotate through the rotating disc 4. Since there is a gap between the connecting block 21 and the movable circular sleeve 20 when the fixed rectangular tube 25 rotates, when the connecting block 21 inside all the fixed rectangular tubes 25 rotates, it will not abut and get stuck with the movable circular sleeve 20. At this time, according to the above working principle, it can be known that the vegetation leaves can continue to be sampled; Every time the rotating mounting plate 9 rotates, it drives all the limiting ball grooves 12 inside the mounting round block 13 to rotate. Each group of limiting ball grooves 12 will abut against the outer wall of the corresponding abutting limiting ball 10, and the abutting limiting ball 10 will limit the rotating mounting plate 9 through the limiting ball grooves 12.

[0033] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
