Description

Technical Field

[0001] The present invention belongs to the technical field related to engineering survey, and more specifically, relates to an integrated sampling device for engineering survey. Background Art

[0002] Engineering survey refers to the activities of mapping, exploring, testing, and providing relevant results and data on topographic, geological, and hydrological conditions to meet the needs of engineering construction planning, design, construction, operation, and comprehensive management. The survey, design, treatment, and monitoring activities in geotechnical engineering also fall under the scope of engineering survey. In engineering survey, geotechnical testing is an important step. Geotechnical testing uses sampling equipment to sample the rock and soil to be tested, and then uses testing instruments to conduct testing and analysis. However, the engineering survey in existing technologies has the following defects:

[0003] In the existing technology, when conducting geotechnical engineering surveys, it is necessary to analyze the composition of the surface. Since the rock and soil are often mixed with a large amount of debris and other debris, manual screening is required during soil testing to screen out the gravel and large-particle rock and soil in the sample. Although this operation can screen out fine soil, a large amount of soil samples will be discarded, which may reduce the accuracy of the soil sample test data.

[0004] In the prior art, during the sampling and screening process of the soil, the sampling device contains some large particles of rock and gravel, which causes the screening structure to be blocked by the large particles of rock and gravel, thereby affecting the screening effect of the fine soil and affecting the sampling of the soil; and the soil is not in sufficient contact with the filter holes, causing some soil to be retained in the filter structure, which will discard a large amount of soil samples and affect the quality of soil sampling.

[0005] In the prior art, when a sampling device is sampling and screening soil, some soil with higher moisture tends to adhere to large rock and soil particles, and the soil is screened out along with the large rock and soil particles, resulting in a large amount of soil samples being discarded, which may reduce the accuracy of soil sample detection data.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and an integrated sampling device for engineering survey is provided, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention provides an integrated sampling device for engineering surveys. By arranging a conical cylinder and a scraper block, the annular plate and the conical cylinder move downward to squeeze the soil in the conical portion, allowing the soil to pass through a plurality of through holes and enter the second cylinder. The rotation of the conical cylinder drives the rotation of the scrapers, which evenly scrape the soil in the conical portion, reducing the accumulation of soil in one place inside the conical portion. This is beneficial for squeezing and crushing large-particle gravel in the soil and squeezing and frictionally separating the soil attached to the large-particle gravel, so that both the gravel and the soil fall through the plurality of through holes into the second cylinder, reducing the discard of soil samples. Furthermore, by arranging grooves, the plurality of grooves are used to make one side of the scraper block have an uneven structure. The uneven structure of one side of the scraper block is used to scrape and separate the gravel from the soil, which is beneficial for improving the efficiency of separating soil and gravel. Finally, when one side of the scraper contacts the inner wall of the tapered portion, the distance between the outer wall of the tapered tube and the inner wall of the tapered portion is smaller than the inner diameter of the through hole. Therefore, the tapered tube moves downward and cooperates with the tapered portion to squeeze and crush large-particle gravel that is larger than the inner diameter of the through hole, thereby preventing large-particle gravel from being blocked in the through hole.

[0021] The present invention provides an integrated sampling device for engineering surveys. This device utilizes an elastic net to filter soil and gravel. Due to the net's conical structure, the filtered gravel is tilted downward into a first collection trough. The soil then passes through the net and falls into a second collection trough. The elasticity of the net creates a spring force when the falling gravel contacts the net. This force causes the gravel to bounce upward, thereby enhancing the separation of soil and gravel. The repeated up-and-down movement of the gravel on the net further reduces soil adsorbed on the gravel, minimizing soil sampling waste. The downward movement of the conical barrel drives several connecting rods downward, which in turn drives a first movable ring downward. This downward movement of the first movable ring reduces the inclination angle of the elastic net. Because the downward movement of the conical barrel causes a greater amount of soil to fall, the reduced inclination angle of the elastic net reduces the speed at which the gravel moves downward on the net, thereby minimizing inadequate separation of soil and gravel. Finally, the upward movement of the conical cylinder drives the connecting rods upward, which in turn drives the first movable ring upward. This upward movement of the first movable ring increases the inclination angle of the elastic net. At this point, since the upward movement of the conical cylinder reduces the amount of soil falling, the increased inclination angle of the elastic net increases the speed at which the gravel moves downward on the elastic net, thereby improving the efficiency of separating the soil and gravel. The inclination angle of the elastic net can be adjusted according to the amount of soil discharged, facilitating the rational separation of gravel and soil and improving the quality of soil sampling.

[0022] The present invention provides an integrated sampling device for engineering surveys. The device comprises an annular housing, a paddle, and a rubber member. Under the action of hot air, the other end of the V-shaped member swings. The swinging of the other end of the V-shaped member pushes the push block to slide, which in turn pushes the paddle to swing. The swinging of the paddle moves the rubber member. Due to the rubber member's compressive contact with the inner wall of the conical portion, the rubber member maintains sliding contact with the interior of the conical portion during the slight swinging of the paddle. This allows the paddle and rubber member to lift a small amount of soil on the paddle upward, reducing soil trapped within the conical portion. Furthermore, a spray valve and a heater heat the gas above the first cylinder. The slight swinging of the paddle drives the rubber member. As the gap between adjacent rubber members widens, the hot air within the annular housing is sprayed upward through the plurality of spray valves, drying the inner wall of the conical portion and reducing soil adsorption on the conical portion and gravel. The hot air is sprayed through the gap between adjacent rubber members, preventing soil from entering the underside of the paddle. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] Specific use of the present invention:

[0061] The control system controls the sampling vehicle 10 to move to the area where samples are to be collected. The two third stepper motors 53 are activated to rotate the two second screw rods 54. The outer walls of the second screw rods 54 make threaded contact with the second slider 52. The two second screw rods 54 rotate, causing the two second sliders 52 to slide horizontally within the two second chute 51, thereby driving the first movable shell 13, the second movable shell 14, the first cylinder 15, the second cylinder 16, and the sampling barrel 17 to move horizontally, thereby facilitating the horizontal position adjustment of the second movable shell 14. The two second stepper motors 49 are activated to drive the two first screw rods 50. The outer walls of the first screw rods 50 make threaded contact with one end of the second movable shell 14. The two first screw rods 50 rotate, driving the second movable shell 14 up and down. The second movable shell 14 moves downward, driving the first cylinder 15, the second cylinder 16, and the sampling barrel 17 downward. The downward movement of the sampling barrel 17 drives the rotating shaft 18 and the drill bit 20 downward, and the drill bit 20 moves downward to contact the ground. At this point, the first stepper motor 40 starts, driving the rotating shaft 18 to rotate. This rotation of the rotating shaft 18 drives the drill bit 20 and the spiral plate 19 to rotate. The drill bit 20 rotates to drill a hole in the ground. The soil from the hole enters the sampling barrel 17. The spiral plate 19 rotates, moving the soil upward to the upper portion of the sampling barrel 17. Several discharge ports 27 allow the soil to enter the tapered portion 28.

[0062] Secondly, the rotation of the rotating shaft 18 drives the spline block 25 to rotate, utilizing the spline block 25 to axially slide within the first chute 26. The rotation of the rotating shaft 18, through the spline block 25 and the first chute 26, drives the second movable ring 23 to rotate. The rotation of the second movable ring 23 drives the rotation of the first slider 24. The rotation of the first slider 24 is guided by the spiral groove 22, causing the second movable ring 23 to move up and down, thereby facilitating the rotation and vertical movement of the second movable ring 23. The rotation of the second movable ring 23 drives the rotation of the connecting blocks 35, which in turn drives the rotation of the annular plate 34 and the conical cylinder 36. Furthermore, the vertical movement of the second movable ring 23 drives the vertical movement of the connecting blocks 35, which in turn drives the vertical movement of the annular plate 34 and the conical cylinder 36. Therefore, the annular plate 34 and the conical cylinder 36 can rotate and move up and down. The spiral groove 22 is interconnected at its end.

[0063] Next, the annular plate 34 and the conical cylinder 36 move downward to squeeze the soil within the conical portion 28, forcing the soil through the plurality of through-holes 29 and into the second cylinder 16. The rotation of the conical cylinder 36 drives the plurality of scrapers 37 to rotate, which evenly scrapes the soil within the conical portion 28, reducing the accumulation of soil in one spot within the conical portion 28. This facilitates the crushing of large-particle gravel in the soil and the separation of soil attached to the large-particle gravel through compression and friction, allowing both gravel and soil to fall through the plurality of through-holes 29 into the second cylinder 16, thus reducing the amount of soil sample discarded. The plurality of grooves 38 provide one side of the scraper 37 with an uneven structure. This uneven structure scrapes and separates the gravel from the soil, improving the efficiency of squeezing the soil through the plurality of through-holes 29 and into the second cylinder 16, and facilitating the separation of soil and gravel. When one side of the scraper 37 contacts the inner wall of the tapered portion 28, the distance between the outer wall of the tapered barrel 36 and the inner wall of the tapered portion 28 becomes smaller than the inner diameter of the through hole 29. As a result, the tapered barrel 36 moves downward, cooperating with the tapered portion 28 to crush large gravel particles larger than the inner diameter of the through hole 29, preventing the large gravel particles from becoming clogged within the through hole 29. The downward movement of the tapered barrel 36 drives the annular plate 34 downward, which in turn blocks and closes the discharge ports 27, preventing soil from entering the interior of the tapered barrel 36.

[0064] Simultaneously, the downward movement of the conical cylinder 36 drives the connecting rods 64 downward, which in turn drives the first movable ring 63 downward. This downward movement of the first movable ring 63 reduces the tilt angle of the elastic net 33. At this point, because the downward movement of the conical cylinder 36 causes a greater amount of soil to fall, the reduced tilt angle of the elastic net 33 reduces the speed at which the gravel moves downward on the elastic net 33, thereby reducing the inadequate separation of the soil and gravel. Furthermore, because the upper ends of the connecting rods 64 are in annular sliding contact with the outer wall of the conical cylinder 36, the rotation of the conical cylinder 36 does not affect the vertical upward and downward movement of the connecting rods 64. The connecting rods 64 can only move vertically upward and downward.

[0065] At the same time, the conical cylinder 36 moves downward, expanding the space above the first cylinder 15. This allows gas outside the first cylinder 15 to be drawn into the first cylinder 15 through the one-way valve 41, or allows gas inside the sampling cylinder 17 to be drawn into the first cylinder 15. At this point, the control system activates the heater 61, which heats the gas above the first cylinder 15.

[0066] Then, the conical cylinder 36 moves upward, forcing the gas in the upper portion of the first cylinder 15 into the annular plate 34, thereby drying the interior of the annular plate 34 and reducing soil adhesion. A portion of the hot gas in the annular plate 34 is ejected through the discharge port 27 into the conical portion 28, thereby drying the interior of the conical portion 28. Another portion of the hot gas in the annular plate 34 passes through the air valve 48 and enters the annular V-shaped member 46. Because one end of the V-shaped member 46 is connected to the inner wall of the annular shell 42, while the other end is not, the hot gas causes the other end of the V-shaped member 46 to swing. The other end of the V-shaped member 46 swings, pushing the push block 47 to slide. The sliding of the push block 47 pushes the selector plate 43 to swing, which in turn moves the rubber member 44. Because the rubber member 44 is in pressurized contact with the inner wall of the tapered portion 28, the rubber member 44 remains in sliding contact with the interior of the tapered portion 28 during the small swings of the selector plate 43. This small swing of the selector plate 43 and the rubber member 44 lifts a small amount of soil on the selector plate 43 upward, reducing the amount of soil trapped within the tapered portion 28. Because the upper side of the selector plate 43 is close to the lowermost through-hole 29, less soil remains on the selector plate 43. The small swings of several selector plates 43, coupled with the connection between adjacent selector plates 43 using the elastic member 60, prevent soil from entering the lower side of the selector plates 43.

[0067] At the same time, the small swing of the paddle 43 drives the rubber member 44 to move. As the gap between two adjacent rubber members 44 expands, the hot air in the annular shell 42 is sprayed upward through the plurality of spray valves 45, thereby drying the inner wall of the conical portion 28, reducing the adsorption of soil on the inner wall of the conical portion 28 and reducing the adsorption of soil on the gravel; and the hot air is sprayed from the gap between two adjacent rubber members 44 to prevent soil from entering the lower side of the paddle 43.

[0068] Finally, the initially separated soil and gravel fall onto the elastic net 33, where they are filtered. Due to the conical structure of the elastic net 33, the filtered gravel moves obliquely downward into the first collection trough 31. The soil then passes through the elastic net 33 and falls into the second collection trough 32. Because the elasticity of the elastic net 33 creates a spring force when the falling gravel contacts it. This force propels the gravel upward, enhancing the separation of the soil and gravel. The repeated up-and-down shaking of the gravel on the elastic net 33 further reduces soil adsorbed on the gravel, minimizing soil sampling waste. Furthermore, the impact of the gravel on the elastic net 33 causes it to vibrate slightly, promoting the separation of soil and gravel and reducing the likelihood of gravel clogging the net 33. The gravel in the first collecting trough 31 enters the collecting box through the first installation opening 58 for storage, and the soil in the second collecting trough 32 enters the sampling shell through the second installation opening 59 for storage.

[0069] The present invention provides an integrated sampling device for engineering surveys. By configuring a conical barrel 36 and scraping blocks 37, the annular plate 34 and conical barrel 36 move downward to squeeze soil within the conical portion 28, forcing the soil through a plurality of through-holes 29 and into the second cylinder 16. The rotation of the conical barrel 36 drives the scraping blocks 37 to rotate, which evenly scrapes the soil within the conical portion 28, reducing soil accumulation within the conical portion 28. This facilitates the crushing of large-particle gravel in the soil and the separation of soil attached to the large-particle gravel through compression and friction, allowing both gravel and soil to fall through the plurality of through-holes 29 into the second cylinder 16, thus reducing the amount of soil sample discarded. Furthermore, the configuration of grooves 38 creates an uneven structure on one side of the scraping blocks 37. This uneven structure scrapes the gravel from the soil, facilitating efficient separation of soil and gravel. Finally, when one side of the scraper 37 contacts the inner wall of the tapered portion 28, the distance between the outer wall of the tapered tube 36 and the inner wall of the tapered portion 28 is smaller than the inner diameter of the through hole 29, so that the tapered tube 36 moves downward and cooperates with the tapered portion 28 to squeeze and crush large-particle gravel that is larger than the inner diameter of the through hole 29, thereby preventing large-particle gravel from being blocked in the through hole 29.

[0070] The present invention provides an integrated sampling device for engineering surveys. The device utilizes an elastic net 33 to filter soil and gravel. Due to the conical structure of the elastic net 33, the filtered gravel is tilted downward and moves into a first collection trough 31. The soil passes through the elastic net 33 and falls into a second collection trough 32. The elasticity of the elastic net 33 creates a spring force when the gravel falls and contacts the net 33. This force causes the gravel to bounce upward, thereby enhancing the separation of soil and gravel. The gravel is repeatedly shaken up and down on the elastic net 33, further reducing soil adsorbed on the gravel and minimizing soil sampling waste. The downward movement of the conical cylinder 36 then drives the connecting rods 64 downward, which in turn drives the first movable ring 63 downward. This downward movement of the first movable ring 63 reduces the tilt angle of the elastic net 33. At this point, since the downward movement of the conical cylinder 36 causes a large amount of soil to fall, the speed at which the gravel moves downwardly on the elastic net 33 is reduced by reducing the inclination angle of the elastic net 33, thereby reducing the inadequate separation of the soil and gravel. Finally, the upward movement of the conical cylinder 36 drives the connecting rods 64 upward, which in turn drives the first movable ring 63 upward. The upward movement of the first movable ring 63 increases the inclination angle of the elastic net 33. At this point, since the upward movement of the conical cylinder 36 causes a small amount of soil to fall, increasing the inclination angle of the elastic net 33 increases the speed at which the gravel moves downwardly on the elastic net 33, thereby improving the efficiency of soil and gravel separation. This allows the inclination angle of the elastic net 33 to be adjusted according to the amount of soil discharged, facilitating the rational separation of gravel and soil and improving the quality of soil sampling.

[0071] The integrated sampling device for engineering surveys of the present invention utilizes an annular housing 42, a paddle 43, and a rubber member 44. Heat causes the other end of a V-shaped member 46 to swing. The swinging of the other end of the V-shaped member 46 pushes a push block 47 to slide, which in turn pushes the paddle 43 to swing. The swinging of the paddle 43 then moves the rubber member 44. Because the rubber member 44 is in compressive contact with the inner wall of the tapered portion 28, the rubber member 44 remains in sliding contact with the interior of the tapered portion 28 during the slight swinging of the paddle 43. This allows the small amount of soil on the paddle 43 to be lifted upwards by the slight swinging of the paddle 43 and rubber member 44, reducing the amount of soil trapped within the tapered portion 28. The spray valves 45 and heater 61 are then configured to heat the gas above the first cylinder 15 using the heater 61. The paddle 43 then swings slightly to move the rubber member 44. As the gap between adjacent rubber members 44 widens, the hot gas within the annular shell 42 is ejected upwardly through the spray valves 45, thereby drying the inner wall of the conical portion 28 and reducing soil adsorption on the inner wall of the conical portion 28 and on the gravel. The hot gas is ejected from the gap between adjacent rubber members 44 to prevent soil from entering the lower side of the paddle 43.
