Description

Technical Field

[0001] The present invention belongs to the technical field related to engineering investigation. More specifically, it particularly relates to an integrated sampling device for engineering investigation. Background Art

[0002] Engineering investigation refers to the activities of surveying, mapping, prospecting and testing the topography, geology and hydrology, etc., and providing corresponding results and data to meet the needs of engineering construction planning, design, construction, operation and comprehensive management, etc. The surveying, design, treatment and monitoring activities in geotechnical engineering also fall within the scope of engineering investigation. In engineering investigation, the detection of rock and soil is an important link. The rock and soil detection samples the rock and soil to be detected through sampling equipment, and then conducts detection and analysis through detection instruments. However, the existing technology in engineering investigation has the following defects: In the prior art, when conducting geotechnical engineering investigation, it is necessary to analyze the components of the ground surface. Since a large amount of debris such as gravel is mixed in the rock and soil, during soil detection, manual screening is required to screen out the gravel and large-grained 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 detection data.

[0003] In the prior art, during the process of sampling and screening soil by the sampling device, there are some large-grained rock and soil and gravel, resulting in the screening structure being blocked by the large-grained rock and soil and gravel, thus affecting the screening effect of fine soil and the sampling of soil; and the contact between the soil and the filter holes is not sufficient, resulting in part of the soil remaining in the filtering structure, and a large amount of soil samples will be discarded, affecting the quality of soil sampling.

[0004] In the prior art, during the process of sampling and screening soil by the sampling device, since some soil with high humidity is easily adhered to the large-grained rock and soil, the soil is screened out together with the large-grained rock and soil, resulting in a large amount of soil samples being discarded, which may reduce the accuracy of the soil sample detection data.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an integrated sampling device for engineering investigation is provided, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0006] The present invention provides an integrated sampling device for engineering investigation to overcome the above defects in the prior art.

[0007] The purpose and effect of an integrated sampling device for engineering investigation of the present invention are achieved by the following specific technical means: An integrated sampling device for engineering investigation, comprising a sampling vehicle body. There is a housing provided on the upper side in the middle of the sampling vehicle body. Inside the housing, there is a U-shaped frame. Horizontally slidably arranged inside the U-shaped frame is a first movable shell. Below the first movable shell is a second movable shell. Below the second movable shell is a first cylinder. Below the first cylinder is a second cylinder. Inside the inner wall of the second cylinder is a sampling cylinder. Rotatably arranged inside the sampling cylinder is a rotating shaft.

At the lower side inside the conical part is an annular shell. Hinged on the upper side of the annular shell are several dial plates.

[0008] A further technical solution is that several connecting rods are connected between the upper side of the first movable ring and the outer wall of the conical cylinder. The outer wall of the connecting rods is in vertical sliding contact with the conical part. The lower end of the connecting rods is fixedly connected to the upper side of the first movable ring. The upper end of the connecting rods is in annular sliding contact with the outer wall of the conical cylinder. The lower side inside the second cylinder is divided by the annular partition into a first collection tank and a second collection tank.

[0009] A further technical solution is that the V-shaped part is of an annular structure. A gas valve is connected and communicated between the inside of the annular shell and the inside of the sampling cylinder. On the upper side of the annular shell are several spray valves. Installed on the upper inner wall of the first cylinder is a heater. Installed on the upper end of the first cylinder is a cover plate. On the cover plate is a one-way valve. On one side of the first collection tank is a first installation opening for installing a collection shell. On the lower side of the second collection tank is a second installation opening for installing a sampling shell.

[0010] Further technical solution: A fixing ring is fixedly arranged at the upper end of the sampling cylinder. A second movable ring is slidably arranged on the inner wall of the fixing ring. The inner wall of the second movable ring is in sliding contact with the outer wall of the upper end of the rotating shaft. A first stepping motor is installed inside the second movable shell, and the output end of the first stepping motor is fixedly connected to the upper end of the rotating shaft.

[0011] Further technical solution: A first sliding groove is arranged on one side of the inner wall of the second movable ring. A spline block is fixedly arranged on the outer wall of the upper end of the rotating shaft, and the spline block axially slides in the first sliding groove.

[0012] Further technical solution: An annular plate is arranged on the inner wall of the conical cylinder. A number of connecting blocks are connected between the inner wall of the annular plate and the outer wall of the second movable ring, and the inner wall of the annular plate is in sliding contact with the outer wall of the sampling cylinder.

[0013] Further technical solution: A spiral groove with its head and tail communicating with each other is arranged on the inner wall of the fixing ring. A first slider is fixedly arranged on one side of the outer wall of the second movable ring, and the first slider spirally slides in the spiral groove.

Two third stepping motors are symmetrically installed on the outer wall of the U-shaped frame.

[0016] Further technical solution: An electric box and a control box are arranged on the upper sides of both ends of the sampling vehicle body. A solar panel is installed on the electric box, and a box body for placing the sampling shell is arranged on the upper side of the shell.

[0017] Compared with the prior art, the present invention has the following beneficial effects: An integrated sampling device for engineering investigation according to the present invention, through the arrangement of a conical cylinder and scraping blocks, the annular plate and the conical cylinder move downward to extrude the soil in the conical part, so that the soil passes through a number of through holes and enters the second cylinder. And the rotation of the conical cylinder drives the rotation of a number of scraping blocks, and the rotation of the number of scraping blocks evenly scrapes the soil in the conical part, reducing the aggregation of soil at one place inside the conical part, which is beneficial to the extrusion and crushing of large-particle gravel in the soil and the extrusion and friction separation of the soil adhering to the large-particle gravel, so that both the gravel and the soil can fall into the second cylinder through a number of through holes, reducing the discard of soil samples. Furthermore, through the arrangement of the grooves, the use of a number of grooves makes one side of the scraping block have an uneven structure, and the uneven structure on one side of the scraping block is used to scrape out and separate the gravel from the soil, which is beneficial to promoting the efficiency of soil and gravel separation. Finally, when one side of the scraping block contacts the inner wall of the conical part, the distance between the outer wall of the conical cylinder and the inner wall of the conical part is smaller than the inner diameter of the through hole, so that the downward movement of the conical cylinder in cooperation with the conical part can extrude and crush large-particle gravel larger than the inner diameter of the through hole, avoiding the blockage of the through hole by large-particle gravel.

[0018] An integrated sampling device for engineering investigation according to the present invention, through the arrangement of an elastic net, the elastic net is used to filter the soil and gravel. Since the elastic net is in a conical structure, the filtered gravel moves obliquely downward into the first collection tank. The soil passes through the elastic net and falls into the second collection tank. Furthermore, due to the elasticity of the elastic net, when the gravel falls and contacts the elastic net, the elastic net can be stressed to generate elastic force. Under the action of the elastic force of the elastic net, the gravel can be bounced upward, thereby improving the separation effect of the soil and the gravel; and the repeated up and down shaking of the gravel on the elastic net is used to further reduce the soil adsorbed on the gravel and reduce the waste of soil sampling. Moreover, the downward movement of the conical cylinder drives the downward movement of a number of connecting rods, and the downward movement of the number of connecting rods drives the downward movement of the first movable ring. The downward movement of the first movable ring reduces the inclination angle of the elastic net. At this time, since the downward movement of the conical cylinder results in a large amount of soil falling, by reducing the inclination angle of the elastic net, the speed of the gravel moving obliquely downward on the elastic net is reduced, thereby reducing the insufficient separation of the soil and the gravel. Finally, the upward movement of the conical cylinder drives the upward movement of a number of connecting rods, and the upward movement of the number of connecting rods drives the upward movement of the first movable ring. The upward movement of the first movable ring increases the inclination angle of the elastic net. At this time, since the upward movement of the conical cylinder results in a small amount of soil falling, by increasing the inclination angle of the elastic net, the speed of the gravel moving obliquely downward on the elastic net is increased, thereby improving the efficiency of soil and gravel separation, so as to be able to adjust the inclination angle of the elastic net according to the feeding amount of the soil, which is beneficial to reasonably separating the gravel and the soil and improving the quality of soil sampling.

[0019] An integrated sampling device for engineering investigation according to the present invention, through the settings of an annular shell, a dial plate, and a rubber part, under the action of hot air, the other end of the V-shaped part swings. The swinging of the other end of the V-shaped part pushes the slider to slide, the sliding of the slider pushes the dial plate to swing, and the swinging of the dial plate drives the rubber part to move. Since the rubber part is in extrusion contact with the inner wall of the conical part, during the small swing of the dial plate, the rubber part is always in sliding contact with the inside of the conical part, so as to use the small swing of the dial plate and the rubber part to pick up a small amount of soil on the dial plate upward, reducing the soil remaining in the conical part. Through the settings of a spray valve and a heater, the heater heats the gas in the upper part of the first cylinder. The small swing of the dial plate drives the rubber part to move. Since the gap between two adjacent rubber parts expands, the hot air in the annular shell is sprayed obliquely upward through several spray valves, thereby drying the inner wall of the conical part, reducing the soil adsorbed on the inner wall of the conical part and reducing the soil adsorbed on the gravel; and using the hot air to spray out from the gap between two adjacent rubber parts to prevent the soil from entering the lower side of the dial plate.

[0035] Preferably, referring to Appendix Figure 13 , two second stepping motors 49 are symmetrically installed inside the first movable shell 13, and two first lead screws 50 are provided at the output ends of the two second stepping motors 49, and both ends of the second movable shell 14 are in threaded contact with the outer walls of the two first lead screws 50 respectively.

[0036] Preferably, referring to Appendix Figure 17 , a second chute 51 is provided on each of the two inner sides of the U-shaped frame 12, a second slider 52 is fixedly provided at each of the two ends of the first movable shell 13, and the second slider 52 slides horizontally in the second chute 51.

[0037] Preferably, referring to Appendix Figure 1 to Appendix Figure 2 , an electric box 55 and a control box 57 are provided on the upper sides of both ends of the sampling vehicle body 10, a solar panel 56 is installed on the electric box 55, and a box body 62 for placing the sampling shell is provided on the upper side of the shell 11.

[0038] In the initial state, the rubber part 44 is in extrusion contact with the inner wall of the conical part 28; the gravel collection box is installed in the first installation opening 58, so that the first collection groove 31 communicates with the collection box; the soil sampling shell is installed in the second installation opening 59, so that the second collection groove 32 communicates with the sampling shell.

[0039] The specific usage method of the present invention: The control system manipulates the sampling vehicle body 10 to move to the area where the sample is to be collected. Two third stepping motors 53 are started to drive two second lead screws 54 to rotate. By using the threaded contact between the outer wall of the second lead screw 54 and the second slider 52, the rotation of the two second lead screws 54 causes the two second sliders 52 to slide horizontally in the two second chutes 51 respectively, thereby driving the first movable shell 13, the second movable shell 14, the first cylinder 15, the second cylinder 16, and the sampling cylinder 17 to move horizontally, so as to facilitate the adjustment of the horizontal position of the second movable shell 14. Two second stepping motors 49 are started to drive two first lead screws 50. By using the threaded contact between the outer wall of the first lead screw 50 and one end of the second movable shell 14, the rotation of the two first lead screws 50 drives the second movable shell 14 to move up and down. The downward movement of the second movable shell 14 drives the first cylinder 15, the second cylinder 16, and the sampling cylinder 17 to move downward. The downward movement of the sampling cylinder 17 drives the rotating shaft 18 and the drill bit 20 to move downward, and the downward movement of the drill bit 20 contacts the ground. At this time, the first stepping motor 40 is started to drive the rotating shaft 18 to rotate. The rotation of the rotating shaft 18 drives the drill bit 20 and the spiral plate 19 to rotate. The rotation of the drill bit 20 drills the ground, and the soil drilled out enters the sampling cylinder 17. The rotation of the spiral plate 19 moves the soil upward, so that the soil moves to the upper part of the sampling cylinder 17. The soil enters the conical part 28 through a number of discharge ports 27.

[0040] Secondly, the rotation of the rotating shaft 18 drives the spline block 25 to rotate. By using the axial sliding contact of the spline block 25 in the first chute 26. The rotation of the rotating shaft 18 drives the second movable ring 23 to rotate through the cooperation of the spline block 25 and the first chute 26. The rotation of the second movable ring 23 drives the first slider 24 to rotate. The rotation of the first slider 24 is helically guided by the spiral groove 22, so that the second movable ring 23 moves up and down, so as to facilitate the rotation and up and down movement of the second movable ring 23. The rotation of the second movable ring 23 drives the annular plate 34 and the conical cylinder 36 to rotate by using a number of cover plates 39. The up and down movement of the second movable ring 23 drives the annular plate 34 and the conical cylinder 36 to move up and down by using a number of cover plates 39. Therefore, the annular plate 34 and the conical cylinder 36 can rotate and move up and down. Among them, the head and tail of the spiral groove 22 are interconnected.

[0041] Next, the annular plate 34 and the conical cylinder 36 move downward to extrude the soil in the conical part 28, so that the soil passes through a number of through holes 29 and enters the second cylinder 16. And the rotation of the conical cylinder 36 drives the rotation of a number of scraping blocks 37. The rotation of the number of scraping blocks 37 evenly scrapes the soil in the conical part 28, reducing the accumulation of soil in one place inside the conical part 28, which is beneficial to the extrusion and crushing of large particle gravel in the soil and the extrusion and friction separation of the soil adhering to the large particle gravel, so that the gravel and the soil both fall into the second cylinder 16 through a number of through holes 29, reducing the discard of soil samples. Among them, a number of grooves 38 are used to make one side of the scraping block 37 have an uneven structure. The uneven structure on one side of the scraping block 37 is used to scrape out and separate the gravel from the soil, and improve the efficiency of the soil being extruded through a number of through holes 29 and falling into the second cylinder 16, which is beneficial to promoting the separation efficiency of the soil and the gravel. When one side of the scraping block 37 contacts the inner wall of the conical part 28, the distance between the outer wall of the conical cylinder 36 and the inner wall of the conical part 28 is less than the inner diameter of the through hole 29. Therefore, the downward movement of the conical cylinder 36 in cooperation with the conical part 28 can extrude and crush large particle gravel larger than the inner diameter of the through hole 29, preventing the large particle gravel from blocking in the through hole 29. The downward movement of the conical cylinder 36 drives the downward movement of the annular plate 34, and the downward movement of the annular plate 34 closes a number of discharge ports 27 to prevent soil from entering the inside of the conical cylinder 36.

[0042] At the same time, the downward movement of the conical cylinder 36 drives the downward movement of a number of connecting rods 64. The downward movement of the number of connecting rods 64 drives the downward movement of the first movable ring 63. The downward movement of the first movable ring 63 reduces the inclination angle of the elastic net 33. At this time, since the downward movement of the conical cylinder 36 results in a large amount of soil falling, by reducing the inclination angle of the elastic net 33, the speed of the gravel moving obliquely downward on the elastic net 33 is reduced, thereby reducing the situation where the separation of the soil and the gravel is insufficient. Among them, since the upper end of the connecting rod 64 is 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 up and down movement of the connecting rod 64. The connecting rod 64 can only move vertically up and down.

[0043] At the same time, the downward movement of the conical cylinder 36 expands the space in the upper part of the first cylinder 15, so that the gas outside the first cylinder 15 is inhaled into the first cylinder 15 through the one-way valve 41 or the gas in the sampling cylinder 17 is inhaled into the first cylinder 15. At this time, the control system controls the heater 61 to start. The heater 61 starts to heat the gas in the upper part of the first cylinder 15.

[0044] Then, the conical cylinder 36 moves upward to squeeze the gas inside the upper part of the first cylinder 15 into the annular plate 34, thereby drying the inside of the annular plate 34 and reducing the soil adhering to the inside of the annular plate 34. A part of the hot air inside the annular plate 34 is ejected into the conical part 28 through the discharge port 27, thereby drying the inside of the conical part 28. And another part of the hot air inside the annular plate 34 enters the annular V-shaped member 46 through the air valve 48. Since one end of the V-shaped member 46 is connected to the inner wall of the annular shell 42 and the other end of the V-shaped member 46 is not connected, under the action of the hot air, the other end of the V-shaped member 46 swings. The swinging of the other end of the V-shaped member 46 pushes the push block 47 to slide, the sliding of the push block 47 pushes the dial plate 43 to swing, and the swinging of the dial plate 43 drives the rubber member 44 to move. Since the rubber member 44 is in pressing contact with the inner wall of the conical part 28, during the small swing of the dial plate 43, the rubber member 44 is always in sliding contact with the inside of the conical part 28, so as to use the small swing of the dial plate 43 and the rubber member 44 to pick up a small amount of soil on the dial plate 43 upward, reducing the soil remaining in the conical part 28. Among them, since the upper side of the dial plate 43 is close to the through hole 29 at the lowermost side, there is less soil remaining on the dial plate 43. The small swings of several dial plates 43 are cooperated with the connection between adjacent two dial plates 43 by the elastic member 60, thereby preventing soil from entering the lower side of the dial plate 43.

[0045] At the same time, the small swing of the dial plate 43 drives the rubber member 44 to move. Since the gap between adjacent two rubber members 44 expands, the hot air inside the annular shell 42 is ejected obliquely upward through several spray valves 45, thereby drying the inner wall of the conical part 28, reducing the soil adsorbed on the inner wall of the conical part 28 and reducing the soil adsorbed on the gravel; and using the hot air ejected from the gap between adjacent two rubber members 44 to prevent soil from entering the lower side of the dial plate 43.

[0046] Finally, the initially separated soil and gravel fall onto the elastic net 33. The elastic net 33 is used to filter the soil and gravel. Since the elastic net 33 is in a conical structure, the filtered gravel moves obliquely downward into the first collection tank 31. The soil passes through the elastic net 33 and falls into the second collection tank 32. Since the elastic net 33 has elasticity, when the gravel falls and contacts the elastic net 33, the elastic net 33 is stressed to generate elastic force. Under the action of the elastic force of the elastic net 33, the gravel can be bounced upward, thereby improving the separation effect of the soil and gravel. And by using the gravel to repeatedly jolt up and down on the elastic net 33, the soil adsorbed on the gravel can be further reduced, and the waste of soil sampling can be reduced. Moreover, by using the gravel to impact the elastic net 33, the elastic net 33 is jolted slightly, which is beneficial to promoting the jolting separation of the soil and gravel and reducing the blockage of the gravel on the elastic net 33. The gravel in the first collection tank 31 enters the collection box through the first installation opening 58 for storage, and the soil in the second collection tank 32 enters the sampling shell through the second installation opening 59 for storage.

[0047] In an integrated sampling device for engineering investigation according to the present invention, through the settings of the conical cylinder 36 and the scraping block 37, the annular plate 34 and the conical cylinder 36 move downward to extrude the soil in the conical part 28, so that the soil passes through a plurality of through holes 29 and enters the second cylinder 16. And the rotation of the conical cylinder 36 drives the rotation of a plurality of scraping blocks 37. The rotation of the plurality of scraping blocks 37 evenly scrapes the soil in the conical part 28, reducing the aggregation of the soil at one place inside the conical part 28, which is beneficial to extruding and crushing the large-particle gravel in the soil and extruding and frictionally separating the soil attached to the large-particle gravel, so that both the gravel and the soil can pass through the plurality of through holes 29 and fall into the second cylinder 16, reducing the discard of soil samples. Furthermore, through the setting of the groove 38, the structure of one side of the scraping block 37 is made uneven by using a plurality of grooves 38. By using the uneven structure on one side of the scraping block 37 to scrape out and separate the gravel from the soil, it is beneficial to improve the separation efficiency of the soil and the gravel. Finally, when one side of the scraping block 37 contacts the inner wall of the conical part 28, the distance between the outer wall of the conical cylinder 36 and the inner wall of the conical part 28 is smaller than the inner diameter of the through hole 29. Thus, the downward movement of the conical cylinder 36 in cooperation with the conical part 28 can extrude and crush the large-particle gravel larger than the inner diameter of the through hole 29, preventing the large-particle gravel from blocking in the through hole 29.

[0048] An integrated sampling device for engineering investigation according to the present invention, through the setting of the elastic net 33, filters soil and gravel by means of the elastic net 33. Since the elastic net 33 is in a conical structure, the filtered gravel moves obliquely downward into the first collection tank 31. The soil passes through the elastic net 33 and falls into the second collection tank 32. Moreover, because the elastic net 33 is elastic, when the gravel falls and contacts the elastic net 33, the elastic net 33 is stressed to generate elastic force. Under the action of the elastic force of the elastic net 33, the gravel can be bounced upward, thereby improving the separation effect of soil and gravel; and by using the gravel to repeatedly move up and down on the elastic net 33, the soil adsorbed on the gravel can be further reduced, reducing the waste of soil sampling. Further, when the conical cylinder 36 moves downward, it drives a plurality of connecting rods 64 to move downward. The plurality of connecting rods 64 moving downward drives the first movable ring 63 to move downward. The downward movement of the first movable ring 63 reduces the inclination angle of the elastic net 33. At this time, since the downward movement of the conical cylinder 36 results in a large amount of soil falling, by reducing the inclination angle of the elastic net 33, the speed of the gravel moving obliquely downward on the elastic net 33 is reduced, thereby reducing the situation where the separation of soil and gravel is insufficient. Finally, when the conical cylinder 36 moves upward, it drives a plurality of connecting rods 64 to move upward. The plurality of connecting rods 64 moving upward drives the first movable ring 63 to move upward. The upward movement of the first movable ring 63 increases the inclination angle of the elastic net 33. At this time, since the upward movement of the conical cylinder 36 results in a small amount of soil falling, by increasing the inclination angle of the elastic net 33, the speed of the gravel moving obliquely downward on the elastic net 33 is increased, thereby improving the separation efficiency of soil and gravel, so that the inclination angle of the elastic net 33 can be adjusted according to the feeding amount of the soil, which is beneficial to reasonably separate the gravel and the soil and improve the quality of soil sampling.

[0049] An integrated sampling device for engineering investigation according to the present invention, through the arrangements of an annular shell 42, a baffle 43 and a rubber member 44, under the action of hot air, the other end of a V-shaped member 46 swings. The swinging of the other end of the V-shaped member 46 pushes a push block 47 to slide, the sliding of the push block 47 drives the baffle 43 to swing, and the swinging of the baffle 43 drives the rubber member 44 to move. Since the rubber member 44 is in extrusion contact with the inner wall of a conical portion 28, during the small swing of the baffle 43, the rubber member 44 is always in sliding contact with the inside of the conical portion 28, so as to use the small swing of the baffle 43 and the rubber member 44 to pick up a small amount of soil located on the baffle 43 upward, reducing the soil remaining in the conical portion 28. Further, through the arrangements of a spray valve 45 and a heater 61, the heater 61 is used to heat the gas in the upper part of a first cylinder 15. The small swing of the baffle 43 drives the rubber member 44 to move. Since the gap between two adjacent rubber members 44 expands, the hot air in the annular shell 42 is sprayed obliquely upward through a plurality of spray valves 45, thereby drying the inner wall of the conical portion 28, reducing the soil adsorbed on the inner wall of the conical portion 28 and reducing the soil adsorbed on gravel; and using the hot air to be sprayed out from the gap between two adjacent rubber members 44 to prevent the soil from entering the lower side of the baffle 43.
