Description

Technical Field

[0001] This invention belongs to the field of sampling technology, and in particular relates to a portable surveying and sampling device. Background Technology

[0002] Soil sampling is a crucial step in surveying work. This step involves randomly selecting a portion of soil from a vast area as samples. Through in-depth study and analysis of these samples, we can infer the overall characteristics of the soil, which has important guiding significance for subsequent soil use, environmental protection, and agricultural planning.

[0003] Sampling requires the use of appropriate sampling equipment. This equipment involves inserting a sampling container into the soil to collect samples. However, in actual sampling, especially when working on drier sites, dust pollution is a common problem. This dust not only affects the accuracy of sampling but, more importantly, poses a threat to the health of workers. Specifically, when the sampling container is inserted into dry soil, the loose soil and friction generate a large amount of dust. This dust permeates the air, forcing workers to work in a dusty environment. Prolonged exposure to this environment leads to the absorption of large amounts of dust into the nasal cavity and other respiratory organs of workers.

[0004] Currently, while some sampling equipment exists on the market, it often falls short in handling the dust generated during the sampling process. These devices typically focus only on the sampling itself, neglecting the impact of dust generated during sampling on the environment and workers. Therefore, effectively solving the dust problem during sampling has become an urgent technical challenge. Summary of the Invention

[0005] This invention provides a portable surveying and sampling device, which aims to solve the problem of the limited use of the currently used surveying and sampling devices mentioned in the background art.

The multiple threaded blocks are respectively fixedly installed on the multiple sampling shells. The threaded sleeves and the threaded blocks are adapted to be threadedly connected, and the threaded sleeves and the connecting sleeves are adapted to be threadedly connected.

[0009] Preferably, the moving mechanism includes: a placement frame disposed on one side of the mounting housing; and a telescopic rod fixedly mounted on the placement frame, wherein the output shaft of the telescopic rod is fixedly connected to the top of the mounting housing.

[0010] Preferably, the collection mechanism includes: a collection box fixedly installed inside the mounting housing, the collection box containing a collection filter bag for collecting dust generated during the sampling process, and a horizontal pipe fixedly installed on the collection box extending to the outside of the mounting housing; a cover threaded onto the collection box, the cover having a connecting pipe; an annular pipe fixedly installed at the bottom of the mounting housing, the annular pipe communicating with the connecting pipe, and the annular pipe having multiple collection ports; and a diversion mechanism provided on the connecting shaft and the collection box for diverting and collecting dust generated during the sampling process.

[0011] Preferably, the drainage mechanism includes: a rotating shaft rotatably mounted on the collection box, with a plurality of fan blades fixedly mounted on the rotating shaft; two synchronous pulleys respectively fixedly sleeved on the rotating shaft and the connecting shaft; and a synchronous belt sleeved on the two synchronous pulleys.

[0012] Preferably, the connecting pipe includes a connector, a vertical pipe, and a flexible hose. The connector is rotatably and sealed on the cover. The vertical pipe is fixedly installed on the mounting shell and is connected to the annular pipe. The flexible hose is rotatably and sealed on the vertical pipe through the mounting head and is threadedly connected to the connector. A positioning frame is fixedly installed on the collecting filter bag, and a positioning block is fixedly installed on the inner wall of the collecting box. The positioning block and the positioning frame are adapted to each other.

[0013] Preferably, the mounting shell has a storage cavity, and a storage rack is fixedly installed in the storage cavity. The storage rack is used to store and place the sampling bucket, and a clamping mechanism is provided in the storage rack for clamping the sampling bucket.

[0014] Preferably, the clamping mechanism includes: a clamping plate disposed within the storage rack; a mounting box fixedly installed within the storage rack, the mounting box containing a spring; and a guide frame slidably installed within the mounting box, the guide frame and the clamping plate being fixedly connected.

[0015] Preferably, a mounting cover is fixedly installed on the bottom of the mounting shell, and a swivel caster is provided on the mounting cover. A placement seat is fixedly installed on the top of the placement rack, and a handle is provided on the placement seat.

[0016] Compared with related technologies, the portable surveying and sampling device provided by this invention has the following advantages: Compared with existing technologies, the portable surveying and sampling equipment provided in this solution first involves pairing multiple sampling shells together during surveying and sampling. When in use, two sampling shells are aligned, with their corresponding threaded blocks. Then, a threaded sleeve is threaded onto the two threaded blocks, thus positioning the two sampling shells together. This process completes the assembly of the sampling bucket. Finally, the corresponding threaded sleeves and connecting sleeves on the sampling bucket are threaded together. During sampling, the operator operates the mounting shell to bring the bottom of the sampling bucket into contact with the ground, then activates the controller to start the servo motor, which drives the connecting shaft to rotate. The bevel gears drive the mounting shaft to rotate, which in turn rotates the sampling bucket. The bottom of the rotating sampling bucket contacts the ground, and the controller activates the telescopic rod to lower the bucket deeper into the soil for sampling. During sampling, the rotating connecting shaft, through the interaction of the synchronous pulley and belt, drives the fan blades on the shaft to rotate. The rotating blades generate suction, creating negative pressure within the ring pipe. Dust generated during sampling enters the ring pipe through the collection port and then passes through the connecting pipe into the collection filter bag for collection, thus reducing dust generation and consequently reducing [dust pollution]. In cases where workers inhale dust through their nasal cavities, after sampling, the workers rotate the connecting sleeve and sampling bucket relative to each other to separate them. Force is then applied to remove the sampling bucket from the soil, thus completing the sampling process. After sampling, when it is necessary to remove the sample from the sampling shell, the workers rotate the threaded sleeve and sampling shell relative to each other to disengage the threaded sleeve and threaded blocks, thereby releasing the two sampling shells from their positioning. This allows for quick and complete removal of the collected soil sample. After removing the sample, the workers align the two sampling shells and then thread the threaded sleeve and the two threaded blocks on the two sampling shells together to fix the two sampling shells in place. The two sampling shells are positioned together and then placed in the storage rack. Before placement, the operator pulls the clamp with one hand, which moves the guide frame within the mounting box to compress the spring. When the operator places the two sampling shells into the storage rack, the clamp is released, and the spring returns to its original position. This clamp holds the two sampling shells in place within the storage rack, preventing them from shaking during movement and improving stability during storage. The entire device allows for surveying and sampling, and can also collect and treat the dust generated during the sampling process, reducing the amount of dust inhaled by the operator's nasal cavity.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This invention provides a portable surveying and sampling device, such as... Figure 1-11 As shown, the portable surveying and sampling device includes: a mounting shaft 2 rotatably mounted on a mounting housing 1; a connecting sleeve 3 fixedly mounted on the mounting shaft 2; a sampling bucket 4 threaded onto the connecting sleeve 3 for surveying and sampling; a sampling mechanism mounted on the mounting housing 1 for driving the sampling bucket 4 to take samples; and a collection mechanism mounted on the mounting housing 1 for collecting dust generated during the sampling process.

[0022] In this embodiment, during surveying and sampling, multiple sampling shells 401 are first matched in pairs. When in use, two sampling shells 401 are aligned, and the threaded blocks 402 on these two shells 401 also correspond. Then, a threaded sleeve 403 is threadedly connected to the two threaded blocks 402, thereby positioning the two sampling shells 401 together. This process completes the assembly of the sampling bucket 4. Then, the corresponding threaded sleeves 403 and connecting sleeves 3 on the sampling bucket 4 are threaded together. During sampling, the operator operates the mounting shell 1 to bring the bottom of the sampling bucket 4 into contact with the ground. Then, the controller is activated to start the servo motor 5, which drives the connecting shaft 6 to rotate. Under the action of the bevel gear 7, the sampling bucket 4 can be... The rotating shaft 2 drives the sampling bucket 4 to rotate, bringing its bottom to contact the ground. The controller then activates the telescopic rod 9 to lower the sampling bucket 4 into the soil for sampling. During sampling, the rotating shaft 6 rotates, and the interaction between the synchronous pulley 19 and the synchronous belt 20 drives the fan blades 18 on the rotating shaft 17 to rotate. The rotating fan blades 18 generate suction, creating negative pressure within the ring pipe 14. Dust generated during sampling enters the ring pipe 14 through the collection port 15 and is then collected in the collection filter bag 11 through the connecting pipe 13. This reduces dust generation and minimizes the inhalation of dust by workers. After sampling is completed, the staff rotates the connecting sleeve 3 and the sampling bucket 4 relative to each other to separate them. Force is then applied to remove the sampling bucket 4 from the soil, thus completing the sampling process. When it is necessary to remove the sample from the sampling shell 401, the threaded sleeve 403 and the sampling shell 401 are rotated relative to each other to disengage the threaded sleeve 403 and the threaded block 402, thereby disengaging the two sampling shells 401 from their positioning. This allows for the quick and complete removal of the collected soil sample. After removing the sample, the staff aligns the two sampling shells 401 and then threads the threaded sleeve 403 onto the two threaded blocks 402 on the two sampling shells 401, thus positioning the two sampling shells 401 in one position. First, the two sampling shells 401 positioned together are placed in the storage rack 23. Before placement, the operator pulls the clamp 24 with one hand. The clamp 24 moves the guide frame 27 within the mounting box 25, compressing the spring 26. Then, when the operator places the two sampling shells 401 positioned together in the storage rack 23, the clamp 24 is released. At this time, the spring 26 returns to its original position, so that the clamp 24 holds the two sampling shells 401 positioned together in the storage rack 23, preventing shaking during movement and improving the stability during storage. Through the entire device, surveying and sampling can be carried out, and the dust generated during the sampling process can be collected and treated, reducing the amount of dust inhaled by the operator's nasal cavity.

[0023] In a further preferred embodiment of the present invention, the sampling bucket 4 includes a plurality of sampling shells 401, a plurality of threaded blocks 402 and a plurality of threaded sleeves 403. The plurality of threaded blocks 402 are respectively fixedly installed on the plurality of sampling shells 401. The threaded sleeves 403 and the threaded blocks 402 are adapted to be threadedly connected, and the threaded sleeves 403 and the connecting sleeves 3 are adapted to be threadedly connected.

[0024] In this embodiment, when using the sampling bucket 4, multiple sampling shells 401 are first matched in pairs. When in use, two sampling shells 401 are aligned, and the threaded blocks 402 on the two sampling shells 401 are also aligned. Then, the threaded sleeve 403 and the two threaded blocks 402 are threaded together, thereby positioning the two sampling shells 401 together. By following this operation, the assembly of the sampling bucket 4 is completed. When in use, the number of sampling shells 401 can be selectively used according to the actual sampling needs, so as to facilitate sampling at different depths. When the sampling is completed and the sample needs to be removed from the sampling shell 401, the threaded sleeve 403 and the sampling shell 401 are rotated relative to each other to disengage the threaded sleeve 403 and the threaded blocks 402, thereby detaching the two sampling shells 401 from their positioning, so that the collected soil sample can be quickly and completely removed.

[0025] In a further preferred embodiment of the present invention, the sampling mechanism includes: a servo motor 5 fixedly installed inside the mounting housing 1; a connecting shaft 6 rotatably installed inside the mounting housing 1, one end of the connecting shaft 6 being fixedly connected to the output shaft of the servo motor 5; two bevel gears 7 respectively fixedly sleeved on the connecting shaft 6 and the mounting shaft 2, and the two bevel gears 7 meshing with each other; and a moving mechanism provided on the mounting housing 1 for driving the sampling bucket 4 to move downwards and penetrate into the soil clod for sampling.

[0026] In this embodiment, a controller is first set on one side of the device. The controller can control the entire device. The working principle of the controller is existing technology and will not be described in detail here. Before using the sampling mechanism, the sampling barrel 4 is first assembled. During assembly, the two sampling shells 401 are aligned, and the threaded blocks 402 on the two sampling shells 401 are also aligned. Then, the threaded sleeve 403 is threadedly connected to the two threaded blocks 402, thereby positioning the two sampling shells 401 together. By following this operation, the assembly of the sampling barrel 4 is completed. Then, the corresponding threaded sleeve 403 on the sampling barrel 4 is threadedly connected to the connecting sleeve 3. The controller starts the servo motor 5 to drive the connecting shaft 6 to rotate. Under the action of the bevel gear 7, the mounting shaft 2 can be driven to rotate, which in turn drives the sampling barrel 4 to rotate. At this time, the bottom of the rotating sampling barrel 4 contacts the ground, and the controller starts the moving mechanism to drive the rotating sampling barrel 4 to move down into the soil, thereby enabling the mapping and sampling work.

[0027] In a further preferred embodiment of the present invention, the moving mechanism includes: a placement frame 8 disposed on one side of the mounting housing 1; and a telescopic rod 9 fixedly mounted on the placement frame 8, wherein the output shaft of the telescopic rod 9 is fixedly connected to the top of the mounting housing 1.

[0028] In this embodiment, after the bottom of the rotating sampling bucket 4 contacts the ground, the staff activates the telescopic rod 9 through the controller to move the rotating sampling bucket 4 down into the soil, so that the surveying and sampling work can be carried out.

[0029] In a further preferred embodiment of the present invention, the collection mechanism includes: a collection box 10 fixedly installed inside the mounting shell 1, wherein the collection box 10 is provided with a collection filter bag 11 for collecting dust generated during the sampling process, and a horizontal pipe 16 is fixedly installed on the collection box 10, the horizontal pipe 16 extending to the outside of the mounting shell 1; a cover 12 threadedly installed on the collection box 10, the cover 12 being provided with a connecting pipe 13; an annular pipe 14 fixedly installed at the bottom of the mounting shell 1, the annular pipe 14 communicating with the connecting pipe 13, and the annular pipe 14 having multiple collection ports 15; and a diversion mechanism provided on the connecting shaft 6 and the collection box 10 for diverting and collecting dust generated during the sampling process.

[0030] In this embodiment, when the start controller starts the servo motor 5 to drive the connecting shaft 6 to rotate, the bevel gear 7 can drive the mounting shaft 2 to rotate, which in turn drives the sampling bucket 4 to rotate. When the connecting shaft 6 rotates, the drainage mechanism is activated. The drainage mechanism generates suction, which creates a negative pressure in the ring tube 14. During the sampling process, the dust generated enters the ring tube 14 through the collection port 15, and then enters the collection filter bag 11 through the connecting pipe 13 to be collected. This reduces the generation of dust and thus reduces the amount of dust inhaled by the staff through their nasal cavity.

[0031] In a further preferred embodiment of the present invention, the drainage mechanism includes: a rotating shaft 17 rotatably mounted on the collection box 10, with a plurality of fan blades 18 fixedly mounted on the rotating shaft 17; two synchronous pulleys 19 respectively fixedly sleeved on the rotating shaft 17 and the connecting shaft 6; and a synchronous belt 20 sleeved on the two synchronous pulleys 19.

[0032] In this embodiment, when the servo motor 5 drives the connecting shaft 6 to rotate, the interaction between the synchronous pulley 19 and the synchronous belt 20 can drive the fan blade 18 on the rotating shaft 17 to rotate. The rotating fan blade 18 generates a functional suction force, which creates a negative pressure in the ring tube 14. During the sampling process, the generated dust enters the ring tube 14 through the collection port 15, and then enters the collection filter bag 11 through the connecting pipe 13 to be collected, thereby reducing the generation of dust and thus reducing the situation where workers inhale dust into their nasal cavity.

[0033] In a further preferred embodiment of the present invention, the connecting pipe 13 includes a connector 1301, a vertical pipe 1302, and a flexible hose 1303. The connector 1301 is rotatably and sealed on the cover 12. The vertical pipe 1302 is fixedly installed on the mounting shell 1 and is connected to the annular pipe 14. The flexible hose 1303 is rotatably and sealed on the vertical pipe 1302 through the mounting head and is threadedly connected to the connector 1301. A positioning frame 21 is fixedly installed on the collecting filter bag 11, and a positioning block 22 is fixedly installed on the inner wall of the collecting box 10. The positioning block 22 and the positioning frame 21 are adapted to each other and connected.

[0034] In this embodiment, when it is necessary to clean the inside of the collection filter bag 11, disconnect the hose 1303 and the connector 1301, then rotate the cover 12 to disengage it from the contact position of the collection filter bag 11, and then take out the collection filter bag 11 for cleaning. After cleaning, place the collection filter bag 11 in the collection box 10, and then thread the cover 12 onto the collection box 10. At this time, the cover 12 will fix the collection filter bag 11 in contact within the collection box 10. Then rotate the connector 1301 to adjust the position of the connector 1301 on the cover 12, and then connect the connector 1301 and the hose 1303.

[0035] In a further preferred embodiment of the present invention, a storage cavity 101 is provided on the mounting shell 1, and a storage rack 23 is fixedly installed in the storage cavity 101. The storage rack 23 is used to store and place the sampling bucket 4, and a clamping mechanism for clamping the sampling bucket 4 is provided in the storage rack 23.

[0036] In this embodiment, when the whole is not in use, the sampling bucket 4 is disassembled and the two sampling shells 401 are aligned. Then, the threaded sleeve 403 is threadedly connected to the two threaded blocks 402 on the two sampling shells 401, thereby positioning the two sampling shells 401 together. Then, the two sampling shells 401 positioned together are placed in the storage rack 23 and fixed in the storage rack 23 by the clamping mechanism, which facilitates the storage of the sampling bucket 4. At the same time, under the action of the clamping mechanism, the shaking during movement can be avoided, improving the stability during storage. In addition, there are baffles at the front and rear of the mounting shell 1, one of which is used to cover the storage cavity 101.

[0037] In a further preferred embodiment of the present invention, the clamping mechanism includes: a clamping plate 24 disposed within the storage rack 23; a mounting box 25 fixedly installed within the storage rack 23, wherein a spring 26 is assembled within the mounting box 25; and a guide frame 27 slidably installed within the mounting box 25, wherein the guide frame 27 and the clamping plate 24 are fixedly connected.

[0038] In this embodiment, when using the clamping mechanism, the operator pulls the clamping plate 24 with one hand. The clamping plate 24 drives the guide frame 27 to move within the mounting box 25, compressing the spring 26. Then, when the operator places the two sampling shells 401 positioned together into the storage rack 23, the operator releases the clamping plate 24. At this time, the spring 26 returns to its original position, thereby clamping the two sampling shells 401 positioned together into the storage rack 23 with the clamping plate 24, preventing shaking during movement and improving the stability during storage.

[0039] In a further preferred embodiment of the present invention, a mounting cover 28 is fixedly mounted on the bottom of the mounting shell 1, and a swivel caster 29 is provided on the mounting cover 28. A placement seat 30 is fixedly mounted on the top of the placement rack 8, and a handle 31 is provided on the placement seat 30.

[0040] In this embodiment, after the sampling work is completed and the sampling bucket 4 is stored, when the entire device needs to be moved, the staff can activate the telescopic rod 9 to adjust the distance between the placement seat 30 and the mounting shell 1, operate the handle 31, and then move the entire device through the omnidirectional wheels 29, thereby facilitating the transfer of the entire device and providing convenience for the staff.

[0041] In summary, compared with related technologies, during surveying and sampling, multiple sampling shells 401 are first matched in pairs. When in use, two sampling shells 401 are aligned, and the threaded blocks 402 on these two shells 401 also correspond. Then, the threaded sleeve 403 is threadedly connected to the two threaded blocks 402, thereby positioning the two sampling shells 401 together. Following this operation, the assembly of the sampling bucket 4 is completed. Then, the corresponding threaded sleeves 403 and connecting sleeves 3 on the sampling bucket 4 are threaded together. During sampling, the operator operates the mounting shell 1 to bring the bottom of the sampling bucket 4 into contact with the ground. Then, the controller is activated to start the servo motor 5, which drives the connecting shaft 6 to rotate. Under the action of the bevel gear 7... The rotating shaft 6 rotates the mounting shaft 2, which in turn rotates the sampling bucket 4. The bottom of the rotating sampling bucket 4 contacts the ground, and the controller activates the telescopic rod 9 to lower the rotating sampling bucket 4 into the soil for sampling. During sampling, the rotating shaft 6 rotates, and the interaction between the synchronous pulley 19 and the synchronous belt 20 drives the fan blades 18 on the rotating shaft 17 to rotate. The rotating fan blades 18 generate suction, creating negative pressure within the ring pipe 14. During sampling, the generated dust enters the ring pipe 14 through the collection port 15 and then enters the collection filter bag 11 through the connecting pipe 13 for collection, thus reducing dust generation and minimizing the amount of dust inhaled by workers. In the case of dust, after sampling, the staff rotates the connecting sleeve 3 and the sampling bucket 4 to separate them. Force is then applied to remove the sampling bucket 4 from the soil, thus completing the sampling process. After sampling, when it is necessary to remove the sample from the sampling shell 401, the threaded sleeve 403 and the sampling shell 401 are rotated relative to each other to disengage the threaded sleeve 403 and the threaded block 402, thereby disengaging the two sampling shells 401 from their positioning. This allows for the quick and complete removal of the collected soil sample. After removing the sample, the staff aligns the two sampling shells 401 and then threads the threaded sleeve 403 onto the two threaded blocks 402 on the two sampling shells 401, thus positioning the two sampling shells 401. The two sampling shells 401 positioned together are placed in the storage rack 23. Before placement, the operator pulls the clamp 24 with one hand. The clamp 24 moves the guide frame 27 within the mounting box 25, compressing the spring 26. When the operator places the two sampling shells 401 positioned together into the storage rack 23, the clamp 24 is released. At this time, the spring 26 returns to its original position, thus clamping the two sampling shells 401 positioned together into the storage rack 23 with the clamp 24, preventing shaking during movement and improving the stability during storage. Through the entire device, measurement and sampling can be carried out, and the dust generated during the sampling process can be collected and treated, reducing the amount of dust inhaled by the operator's nasal cavity.
