Description

Technical Field

[0001] This utility model relates to the field of ecological monitoring and sampling technology, and in particular to a forest and grassland ecological monitoring and sampling device. Background Technology

[0002] Forest and grassland ecological monitoring sampling refers to the process of selecting representative sampling points or plots for field investigation and data collection within forest and grassland ecosystems, in order to assess their health status, biodiversity, ecological functions, and monitor ecological changes, according to certain principles and methods. This process involves measuring and recording the species, quantity, distribution, and growth status of forest and grassland vegetation, as well as related ecological factors such as soil and water quality. Soil sampling is a crucial step in forest and grassland ecological monitoring sampling, playing a significant role in assessing soil quality and monitoring soil pollution. Currently, soil sampling typically involves directly using a soil sampler, inserting it into the soil, and then using the sampling tube at the front end of the sampler to extract the soil. However, existing soil samplers require inserting the sampling tube to different depths for sampling at different depths, resulting in slow sampling efficiency and cumbersome, time-consuming, and labor-intensive operations. Utility Model Content

[0003] The purpose of this invention is to provide a forest and grassland ecological monitoring sampling device that can conveniently and simultaneously sample soil at different depths, greatly improving sampling efficiency and being easy to operate, saving time and effort.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A forest and grassland ecological monitoring sampling device includes a drill barrel, one end of which is rotatably connected to a drill bit. A motor for driving the drill bit to rotate is installed inside the drill barrel near the drill bit. Multiple sampling ports are opened on the outer side of the drill barrel at equal intervals. Multiple threaded sleeves corresponding to and communicating with the sampling ports are arranged at equal intervals inside the drill barrel. A limiting sleeve is rotatably connected to the outer side of each threaded sleeve away from the corresponding sampling port. A sampling sleeve that is threadedly connected to the corresponding threaded sleeve is slidably connected inside each limiting sleeve.

[0006] Each sampling sleeve has a piston block slidably connected inside. Each piston block has a horizontally arranged limiting shaft at the end away from the corresponding limiting port, which passes through the corresponding sampling sleeve and the corresponding limiting sleeve and extends into the inside of the drill barrel. Each limiting shaft has a limiting block at the end away from the corresponding piston block. A spring is arranged on the outer side of each limiting shaft between the limiting block and the corresponding limiting sleeve. A vertically arranged drive rod is rotatably connected inside the drill barrel. An intermittent bevel gear is arranged on the outer side of the drive rod near each limiting sleeve. An annular bevel gear that meshes with the corresponding intermittent bevel gear is arranged on the outer side of each limiting sleeve away from the corresponding sampling port. A cam that cooperates with each limiting block and is opposite to each intermittent bevel gear is arranged on the outer side of the drive rod near each limiting block. A power line for connecting to a power source to provide power is arranged on the outer side of the drill barrel.

[0007] By adopting the above technical solution, during use, the motor is first started, driving the drill bit to rotate. This rotation facilitates the insertion of the drill barrel into the soil. Then, the motor is turned off, and the drive rod is rotated towards the limiting port. The drive rod's rotation drives the intermittent bevel gear to rotate, which meshes with the ring bevel gear, causing the ring bevel gear to rotate. The ring bevel gear then drives the limiting sleeve to rotate relative to the threaded sleeve. The limiting sleeve causes the sampling sleeve to rotate accordingly, and the sampling sleeve rotates relative to the threaded sleeve, causing the sampling sleeve to slide relative to the limiting sleeve, allowing sampling sleeves at different depths to slide from their corresponding sampling points. The drill bit is drilled out of the sampling port, and soil is sampled through the sampling sleeve. Then, the drive rod is rotated away from the limiting port, causing the intermittent gear to drive the ring bevel gear to rotate in the opposite direction, thus returning the sampling sleeve to the limiting sleeve. The drill bit is then pulled out of the soil. By continuing to rotate the drive rod away from the limiting port, the drive rod drives the cam to rotate. The cam pushes the limiting block to move the limiting shaft, which compresses the spring and generates elastic force. The limiting shaft drives the piston block to move relative to the sampling sleeve, which facilitates the removal of soil from the sampling sleeve. Then, under the action of the spring force, the piston block can be reset.

[0008] A further feature of this invention is that each limiting sleeve has a limiting slide opening on its outer side that is equally spaced from multiple limiting slide openings, and each sampling sleeve has multiple sliders on its outer side away from the corresponding sampling port that are slidably connected to the corresponding limiting slide opening.

[0009] By adopting the above technical solution, the limiting sleeve can be conveniently used to drive the sampling sleeve to rotate.

[0010] A further feature of this invention is that a handle is provided at the outer end of the drill barrel away from the drill barrel.

[0011] A further feature of this invention is that the end of the drive rod away from the drill barrel extends out of the drill barrel and is provided with a drive handle.

[0012] A further feature of this invention is that a control button is provided at the end of the drill barrel away from the drill bit.

[0013] A further feature of this invention is that each sampling sleeve has a serrated end near the corresponding sampling port.

[0014] By adopting the above technical solution, the sampling sleeve can be easily inserted into the soil.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Firstly, it can conveniently sample soil at different depths simultaneously, improving sampling efficiency. The drive rod drives the intermittent bevel gear to rotate in different directions, which in turn drives the ring bevel gear to rotate in different directions. The ring bevel gear drives the limiting sleeve to rotate, which in turn drives the sampling sleeve to rotate relative to the threaded sleeve in different directions. This allows the sampling sleeve to extend from the sampling port to complete the soil sampling operation at different depths, and then it returns to the limiting sleeve. The operation is simple, thus improving the soil sampling efficiency.

[0017] Secondly, by rotating the drive rod, the cam pushes the limit block, which compresses the spring and drives the limit shaft to push the piston block to move in the sampling sleeve, thereby pushing the soil in the sampling sleeve out, which facilitates the collection of the sampled soil. The elastic force generated by the spring compression can drive the piston block to reset. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Example, refer to Figure 1-5 A forest and grassland ecological monitoring sampling device includes a drill cylinder 1, a drill bit 2 rotatably connected to the lower end of the drill cylinder 1, a motor 3 for driving the drill bit 2 to rotate installed at the lower end inside the drill cylinder 1, a handle 19 provided at the upper end of the outer side of the drill cylinder 1, a control button 20 provided on the right side of the upper end of the drill cylinder 1, and a power cord 21 for connecting to a power source to provide power at the rear side of the upper end of the drill cylinder 1.

[0029] Five sampling ports 4 are equally spaced on the outer side of the drill barrel 1. Five threaded sleeves 5 are equally spaced inside the drill barrel 1, each corresponding to one of the sampling ports 4 and communicating with each other. A limiting sleeve 6 is rotatably connected to the left end of the outer side of each threaded sleeve 5. A sampling sleeve 8 is slidably connected inside each limiting sleeve 6 and threadedly connected to the corresponding threaded sleeve 5. Two limiting sliding openings 7 are equally spaced on the outer side of each limiting sleeve 6. Two sliders 9 are equally spaced on the left end of the outer side of each sampling sleeve 8 and slidably connected to the corresponding limiting sliding openings 7. This allows the limiting sleeve 6 to drive the sampling sleeve 8 to rotate. The sampling sleeve 8 rotates relative to the threaded sleeve 5 and slides relative to the limiting sleeve 6.

[0030] Each sampling sleeve 8 has a piston block 10 slidably connected inside. The left end of each piston block 10 passes through the corresponding sampling sleeve 8 and the corresponding limiting sleeve 6 and extends into the drill barrel 1. A limiting shaft 11 is horizontally arranged inside the drill barrel 1. A limiting block 12 is arranged at one end of each limiting shaft 11 that extends into the drill barrel 1. A spring 13 is arranged on the outside of each limiting shaft 11 between the corresponding limiting block 12 and the corresponding limiting sleeve 6, which can drive the piston block 10 to reset.

[0031] A vertically arranged drive rod 14 is rotatably connected to the upper left side of the inside of the drill barrel 1. A ring bevel gear 17 is provided at the left end of the outer side of each limiting sleeve 6. Five intermittent bevel gears 15, which correspond one-to-one with the ring bevel gears 17, are provided at equal intervals on the outer side of the drive rod 14. Each intermittent bevel gear 15 meshes with the corresponding ring bevel gear 17. A cam 16 is provided on the outer side of the drive rod 14 near each limiting block 12, which cooperates with it and is positioned opposite to each intermittent bevel gear 15. A drive handle 18 is provided at the upper end of the drive rod 14 through the drill barrel 1.

[0032] Usage: First, connect the power cord 21 to the power supply. Then, start the motor 3 using the control button 20. The motor 3 drives the drill bit 2 to rotate. Hold the handle 19 and push the drill bit 2 into the soil to facilitate inserting the drill barrel 1. Then, turn off the motor 3 using the control button 20. Turn the drive handle 18 towards the limit port to rotate the drive rod 14. The drive rod 14 drives the intermittent bevel gear 15 to rotate. The intermittent bevel gear 15 meshes with the annular bevel gear 17, causing the annular bevel gear 17 to rotate. The annular bevel gear 17 causes the limit sleeve 6 to rotate relative to the threaded sleeve 5. The limit sleeve 6, through the limit slide 7, causes the slider 9 to rotate. The slider 9 causes the sampling sleeve 8 to rotate relative to the threaded sleeve 5, causing the slider 9 to slide relative to the limit slide 7. The sampling sleeve 8 slides relative to the limiting sleeve 6, allowing sampling sleeves 8 at different depths to drill out from the corresponding sampling port 4. Soil samples are taken through the sampling sleeve 8. Then, the drive handle 18 is rotated away from the limiting port, causing the drive rod 14 to rotate. This causes the intermittent gear to drive the ring bevel gear 17 to rotate in the opposite direction, thus allowing the sampling sleeve 8 to return to the limiting sleeve 6. The drill 1 is then pulled out of the soil. By continuing to rotate the drive rod 14 away from the limiting port, the drive rod 14 drives the cam 16 to rotate. The cam 16 pushes the limiting block 12 to move the limiting shaft 11, compressing the spring 13 and generating elastic force. The limiting shaft 11 drives the piston block 10 to move relative to the sampling sleeve 8, facilitating the removal of soil from the sampling sleeve 8. Then, under the elastic force of the spring 13, the piston block 10 can be reset.

[0033] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
