Description

Technical Field

[0001] The utility model relates to the technical field of forestry exploration, in particular to a forestry exploration soil-taking tool. Background Art

[0002] Forestry exploration and soil sampling is a key activity in forestry resource management. It involves collecting and analyzing soil samples using scientific methods to assess the quality and fertility of forestland. This process is crucial for guiding forestry production, protecting the ecological environment, and promoting sustainable forestry development. During forestry exploration and soil sampling, professionals use specialized exploration tools and equipment to collect soil samples within selected forest areas. The sampling process adheres to specific specifications and standards to ensure representativeness and accuracy. Furthermore, prospectors conduct detailed observations and record natural conditions, such as the forestland's topography and vegetation, to obtain a more comprehensive picture. Laboratory analysis of collected soil samples reveals information on the soil's physical and chemical properties, as well as its biological activity. This information is crucial for selecting appropriate tree species for planting, developing effective forestry management measures, and assessing the forestland's production potential.

[0003] Existing technology usually uses a soil sampling drill for sampling soil within ten meters of the ground surface. A soil sampling drill is a device specifically used to collect soil samples. The working principle of the soil sampling drill is to use a power mechanism to drive the drilling mechanism to rotate, thereby driving the drill rod and drill bit to rotate and push into the soil. Under the cutting action of the drill bit, the soil is drilled into the drill rod and collected and stored by a coring device. However, sometimes the depth of soil sampling does not need to be that deep. If a soil sampling drill is used, even a small soil sampling drill is large in size and weight. Carrying a large and heavy sampling drill is undoubtedly a burden for the staff.

[0004] In order to facilitate soil sampling for forestry exploration workers, it is necessary to develop a soil sampling tool suitable for forestry exploration, which can be used for soil sampling below three meters. It is convenient for exploration workers to carry and can reduce the labor intensity of workers. Utility Model Content

[0005] In view of the above shortcomings, the utility model provides a forestry exploration soil sampling equipment that can be conveniently carried by forestry exploration personnel and can perform soil sampling work more labor-savingly.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A forestry exploration and soil sampling tool includes a drill bit and a sampling tube, a connecting pipe, a rotating rod and a rotating clamping device. The drill bit is installed at the lower part of the sampling tube, the connecting pipe is arranged between the sampling tube and the rotating rod for connecting the sampling tube and the rotating rod, and the rotating clamping device is sleeved on the rotating rod.

[0008] Preferably, the rotating clamping device includes a fixed ring, a rotating clamp and a first connecting piece. There are two fixed rings, which are concentrically arranged. There are two first connecting pieces. The rotating clamp is movably arranged between the two fixed rings and connected through the two first connecting pieces.

[0009] Preferably, the rotating clamp includes a rotating ring, a fixing part and a clamping part. There are two rotating rings, which are concentrically arranged with the fixing ring. There are two fixing parts, which are located between the two rotating rings and fix the two rotating rings. The clamping part includes a sliding rod, a slider and a splint. There are two sliders and they are axially symmetrically arranged on the rotating ring. A through hole is provided on the slider. There are two sliding rods, which are rotatably arranged on the first connecting part in a one-to-one manner and pass through the slider. The splint is rotatably arranged on the end of the sliding rod away from the first connecting part.

[0010] Preferably, the rotary clamp further includes a handle, a second connecting piece is provided on the outside of the fixing piece, and there are two handles which are detachably mounted on the second connecting pieces on the fixing piece.

[0011] Preferably, the sampling tube includes a first sampling tube and a second sampling tube, and the first sampling tube and the second sampling tube are half-circular tubes with the same diameter and length.

[0012] Preferably, the fixing ring further includes a stopper, and the rotating rod further includes a limiting block, the stopper is arranged inside the fixing ring, and the limiting block is axially arranged on the rotating rod.

[0013] Preferably, the drill bit comprises a drill pipe and blades, the drill pipe is a hollow tube, and the blades are multiple and spirally arranged on the outer wall of the drill pipe.

[0014] Preferably, the thickness of the blade near the lower portion of the drill pipe is smaller than that near the upper portion of the drill pipe.

[0015] Preferably, both ends of the sampling tube are provided with external threads, the drill tube and the connecting tube are provided with internal threads matching the external threads, and the drill tube and the connecting tube are connected to the sampling tube via the threads.

[0016] Preferably, the inner diameters of the drill pipe, the connecting pipe and the sampling pipe are the same.

[0017] The beneficial effects of the utility model are as follows:

[0018] 1. The utility model has a simple structure and adopts a modular design. Each component can be disassembled and stored, making it easy for prospectors to carry. When the device is inserted into the soil for sampling, the rotating clamping device is rotated. The rotating clamping device can achieve two actions: grasping and releasing. The greater the rotational force, the greater the clamping force of the rotating clamping device. During the process, when the sampling tube is drilled into the soil, it is necessary to adjust the height of the rotating clamping device to enable the staff to achieve the most comfortable working posture. The rotating clamping device only needs to be rotated in the opposite direction. The rotating clamping device can quickly loosen the rotating rod, improving the staff's sampling efficiency. At the same time, the use of force can provide the drill bit with force to rotate and cut the soil, which is more suitable for dealing with soil sampling environments with higher hardness.

[0019] 2. To help workers rotate the rotating ring with minimal effort, the rotating fixture also includes a handle. The handle is detachably mounted to the rotating fixture via a threaded connection and can be removed for easy portability when not in use. Based on the principle of leverage, the longer the handle, the longer the rotating arm, the less effort required to rotate the rotating ring. The appropriate handle length can be selected based on soil hardness and sampling depth to reduce worker exertion. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In the prior art, soil sampling drills can sample soil at a depth of several meters to tens of meters, depending on the model. However, even small soil sampling drills are large in size and weight, and carrying a large and heavy sampling drill is undoubtedly a burden for workers. In order to facilitate soil sampling for forestry exploration workers, the utility model provides a soil sampling tool for forestry exploration, which is suitable for soil sampling work below three meters. Figure 1As shown, a soil sampling tool for forestry exploration includes a sampling tube 2, a drill bit 1, a connecting tube 3, a rotating rod 4 and a rotating clamping device 5. The drill bit 1 is installed at the lower part of the sampling tube 2, wherein the connecting tube 3 is used to connect the rotating rod 4 and the sampling tube 2. The rotating clamping device 5 is set on the rotating rod 4. When it is necessary to sample the soil, the rotating clamping device 5 is rotated. The rotating clamping device 5 can clamp the rotating rod 4 and drive the soil sampling tool to drill into the soil layer. The drill bit 1 can cut the soil layer and send the cut soil sample into the sampling tube 2 to complete the soil sampling. The various components are detachably connected. The utility model has a simple structure and adopts a modular design. Each component can be disassembled and stored, making it easy for prospectors to carry. When the device is inserted into the soil for sampling, the rotating clamping device 5 is rotated. The rotating clamping device 5 can achieve two actions: grasping and releasing. The greater the rotation force, the greater the clamping force of the rotating clamping device 5. During the process, after the sampling tube 2 is drilled into the soil, it is necessary to adjust the height of the rotating clamping device 5 to allow the staff to achieve the most comfortable working posture. The rotating clamping device 5 only needs to be rotated in the opposite direction. The rotating clamping device 5 can quickly loosen the rotating rod 4, thereby improving the staff's sampling efficiency. At the same time, the use of force can provide the drill bit 1 with a force for rotating and cutting the soil, which is more suitable for coping with soil sampling environments with higher hardness.

[0032] Preferably, in order to achieve the above-mentioned effect, the rotating clamping device 5 includes a fixed ring 51, a rotating clamp and a first connecting member 52; a circular ring with a through hole is provided in the middle of the fixed ring 51, the inner diameter of the fixed ring 51 is larger than the outer diameter of the rotating rod 4, two through holes are axially symmetrically provided on the fixed ring 51, there are two fixed tubes, the two fixed rings 51 are concentrically arranged, and there is a gap between the two fixed rings 51, there are two first connecting members 52, which are correspondingly arranged in the through holes on the fixed ring 51 for fixing the fixed ring 51, and the rotating clamp is movably arranged between the two fixed rings 51 and connected to the two first connecting members 52.

[0033] like Figures 2 to 4 As shown, the rotating clamp includes a rotating ring 59, a fixing member 57 and a clamping member. A through hole is provided in the middle of the rotating ring 59 and the diameter thereof is larger than the diameter of the rotating rod 4. Two through holes are axially symmetrically provided on the rotating ring 59. There are two rotating rings 59, and the two rotating rings 59 are concentrically arranged with the fixing ring 51. There are two fixing members 57, and the two fixing members 57 are located between the two rotating rings 59 and fix the two rotating rings 59. It can be easily seen that there is a gap between the two rotating rings 59, and the clamping member is provided between the gap formed by the two rotating rings 59, and the outer diameter of the rotating ring 59 is smaller than the straight-line distance between the two first connecting members 52.

[0034] The clamping component includes a slide bar 54, a slider 55, and a clamping plate 56. The slider 55 is a small square with a side length smaller than the gap distance formed by the two rotating rings 59. The slider 55 is provided with a through hole and a connecting piece is provided at the upper and lower ends of the slider 55. There are two sliders 55, and they are rotatably set between the two rotating rings 59 through the connecting piece provided thereon. The slide bar 54 is cylindrical, and the diameter of the cylinder is smaller than the through hole provided on the slider 55. A through hole is provided at one end of the cylinder, and the diameter of the through hole is larger than the diameter of the first connecting piece 52. There are two slide bars 54, which are rotatably set on the first connecting piece 52 in a one-to-one correspondence and pass through the slide bar 55. The clamping plate 56 is an arc with a curvature, and the diameter of the arc is the same as that of the rotating rod 4. A connecting piece connected to the slide bar 54 is provided on the outside of the clamping plate 56. The clamping plate 56 is rotatably mounted on the end of the slide bar 54 away from the first connecting piece 52.

[0035] When the rotating clamping device 5 is rotated, it is the rotating clamp within it that rotates, while the fixed ring 51 and the rotating rod 4 are relatively stationary. The rotating clamp rotates within the gap between the two fixed rings 51, and the rotating ring 59 drives the slider 55 to rotate. Since one end of the sliding rod 54 located within the slider 55 is rotatably mounted on the first connecting member 52, the rotating force of the slider 55 causes the sliding rod 54 to extend into the rotating ring 59. The clamping plate 56 on the clamping plate cooperates to clamp the rotating rod 4, achieving the clamping operation. To release the clamping plate 56 from the rotating rod 4, the operation is achieved by flipping the rotating ring 59. This device is easy to operate, saves time, and improves work efficiency.

[0036] Preferably, to allow workers to rotate the rotating ring 59 with less effort, the rotating fixture further includes a handle 510. A threaded hole is provided at one end of the handle 510. A second connecting member 58 is provided on the outside of the fixing member 57 in the rotating fixture. The second connecting member 58 is a stud that matches the threaded hole of the handle 510. The handle 510 is detachably mounted on the rotating fixture via a threaded connection. When not in use, the handle 510 can be removed for easy carrying. Furthermore, according to the principle of leverage, the longer the handle 510, that is, the longer the rotating power arm, the less effort is required to rotate the rotating ring 59. The appropriate length of the handle 510 can be selected based on soil hardness and sampling depth.

[0037] Preferably, Figure 5 As shown, in order to facilitate the removal of soil samples from the sampling tube 2, the sampling tube 2 includes a first sampling tube 21 and a second sampling tube 22. The first sampling tube 21 and the second sampling tube 22 are half-circular tubes with the same diameter and length. When it is necessary to remove the soil sample, the drill bit 1 and the connecting tube 3 installed at both ends are removed, and the soil sample can be removed from the first sampling tube 21 and the second sampling tube 22.

[0038] Preferably, to prevent the fixed ring 51 from being unable to be fixed when the rotating ring 59 is rotated, the fixed ring 51 further includes a stopper 53, and the rotating rod 4 further includes a limit block 41. The stopper 53 is disposed inside the fixed ring 51, and the limit block 41 is axially disposed on the rotating rod 4. When the rotating ring 59 is rotated, the limit block 41 on the rotating rod 4 can effectively prevent the fixed ring 51 from rotating with the rotating ring 59.

[0039] Preferably, Figure 6 As shown, the drill bit 1 includes a drill pipe 11 and blades 12. The drill pipe 11 is hollow and has cutting teeth at its lower portion for cutting the soil. The blades 12 consist of three pieces, spirally attached to the outer wall of the drill pipe 11. The blades 12, rotatably mounted on the outer wall of the drill pipe 11, provide lateral resistance. As the drill pipe 11 rotates, the spirally mounted blades 12 exert a downward force, facilitating the drill bit 1's penetration into the soil. Furthermore, to reduce longitudinal resistance, the blades 12 are thinner near the lower portion of the drill pipe 11 than near the upper portion, resulting in a sharper lower portion.

[0040] Preferably, to facilitate disassembly and installation between components, external threads are provided at both ends of the sampling tube 2, and the drill pipe 11 and the connecting pipe 3 are provided with internal threads matching the external threads, and the drill pipe 11 and the connecting pipe 3 are connected to the sampling tube 2 through threads.

[0041] In other preferred embodiments, the rotating rod 4 connected to the upper portion of the connecting tube 3 can be replaced with a sampling tube 2. A new connecting tube 3 is connected to the connected sampling tube 2 and connected to the rotating rod 4. In this way, multiple sampling tubes 2 can be linked together to form a longer structure, allowing sampling of deeper soil layers, thereby increasing the applicability of the tool.

[0042] Preferably, in order to facilitate the smooth insertion of the cut soil sample into the sampling tube 2, the inner diameters of the drill tube 11, the connecting tube 3 and the sampling tube 2 are the same.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
