[0001] This invention relates to the field of soil sampling equipment technology, specifically a rapid soil sampling device for civil engineering. Background Technology

[0002] In civil engineering, soil sampling and testing are required to determine whether the soil environment meets the construction requirements. Therefore, soil samples need to be taken from different depths. The soil sampling device usually needs a support frame for positioning or support to install the soil sampling device and ensure its stability.

[0003] Existing rapid soil removal devices for civil engineering are generally used on relatively flat terrain. When the working terrain is a slope, the load-bearing frame is generally not adjustable, so it is easy for it to tilt, especially during the soil removal process, as the weight is constantly increasing, which can easily cause the center of gravity to deviate and cause tilting.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] Please see Figures 1 to 9 This embodiment provides a rapid soil sampling device for civil engineering, including a bearing mechanism 1 and a soil sampling mechanism 2, and an auxiliary support mechanism 3. The auxiliary support mechanism 3 and the soil sampling mechanism 2 are both mounted on the bearing mechanism 1. The auxiliary support mechanism 3 includes a rotating housing 31, an adjustable support rod 32, a clamping part 33, a support part 34, an adjustable transmission gear 35, and a drive gear 36. The rotating housing 31 is coaxially connected to the adjustable transmission gear 35, and the adjustable transmission gear 35 and the drive gear 36 are meshed. One end of the adjustable support rod 32 is movably connected to the clamping part 33, and the clamping part 33 is in contact with the surface of the soil sampling mechanism 2. The adjustable support rod 32 is rotatably connected to the bearing mechanism 1, and the adjustable support rod 32 is also movably connected to the rotating housing 31. One end of the support part 34 is slidably connected to the soil sampling mechanism 2, and the other end of the support part 34 is movably connected to the clamping part 33.

[0029] Furthermore, the bearing mechanism 1 includes a fixed frame 11 and a support frame 12. The support frame 12 is installed on the fixed frame 11, and the soil sampling mechanism 2 is installed between the fixed frame 11 and the support frame 12. A fixed plate 16 is fixedly connected to the fixed frame 11, and a fixed pipe 121 is fixedly connected to the support frame 12. The inner wall of the fixed pipe 121 is provided with a first limiting groove 122 extending along the axial direction.

[0030] Furthermore, a threaded tube 14 is fixedly connected to the support frame 12, and a threaded rod 13 is internally threaded to the threaded tube 14. One end of the threaded rod 13 is inserted and connected to the ground, and a knob 131 is installed at the other end of the threaded rod 13. An adjustable roller 15 is also rotatably connected to the side wall of the support frame 12.

[0031] Furthermore, the center position of one side of the drive gear 36 is connected to the support frame 12 via a rotating rod 362, and the eccentric position of the other side of the drive gear 36 is connected to a hand crank 361. Of course, a drive motor can also be installed on the support frame 12, and the rotating rod 362 can be connected to the drive motor to realize the function of using the drive motor to drive the drive gear 36 to rotate.

[0032] In the above scheme, when the terrain or location for soil extraction is a slope, the device is first moved to the slope surface using the adjustable roller 15. Then, the threaded rod 13 is driven into the slope by rotating the knob 131. Next, the adjustable roller 15 is rotated to remove it from the slope surface. Immediately afterwards, the adjustable transmission gear 35 is rotated by rotating the drive gear 36. The rotating adjustable transmission gear 35 drives the rotating housing 31 to rotate. The rotating housing 31 can drive the adjustable support rod 32 to rotate at a certain angle. The adjustable support rod 32 is designed as a telescopic rod, and its length can be adjusted to insert it into the slope. This makes the device more stable and prevents tilting. At the same time, the rotating adjustable support rod 32 can also drive the clamping part 33 to make linear movement. The clamping part 33 is symmetrically distributed on both sides of the soil sampling mechanism 2. The support part 34 on the clamping part 33 can also support the soil sampling mechanism 2. The design of the clamping part 33 and the support part 34 working together can prevent the tilted soil sampling mechanism 2 from shaking or breaking or deforming due to uneven force during operation. This solves the problem that existing rapid soil sampling devices for civil engineering cannot work stably on sloping terrain.

[0033] Please see Figure 3 , Figures 8 to 9As one embodiment of this application, an eccentric rod 312 is fixedly connected to the eccentric position of the rotating housing 31. The eccentric rod 312 is rotatably connected to the bearing mechanism 1. A circular guide rail 311 is provided on the side of the rotating housing 31 away from the eccentric rod 312. A first limiting rib 313 extending along the axial direction is connected to the surface of the eccentric rod 312.

[0034] In the above scheme, the rotating eccentric rod 312 can drive the rotating housing 31 to perform eccentric rotational motion.

[0035] Please see Figures 2 to 3 , Figures 8 to 9 As one embodiment of this application, a rotating tube 351 is fixedly connected to the center position of the adjustable transmission gear 35. The rotating tube 351 is movably sleeved inside the fixed tube 121. The outer wall of the fixed tube 121 is connected to a second limiting rib 352 that is inserted into the first limiting groove 122. The inner wall of the fixed tube 121 is provided with a second limiting groove 353 that is inserted into the first limiting rib 313. The length of the eccentric rod 312 inserted into the rotating tube 351 is not less than the length of the second limiting rib 352 inserted into the first limiting groove 122. A push-pull ring 354 is connected to the side of the adjustable transmission gear 35 away from the rotating tube 351.

[0036] In the above scheme, after the angle of the adjustable support rod 32 is adjusted, the operator pulls the push-pull ring 354 to drive the adjustable transmission gear 35 to move along the axis of the rotating tube 351 until the second limiting rib 352 on the rotating tube 351 is completely inserted into the first limiting groove 122 in the fixed tube 121. Since the fixed tube 121 is fixed, the limiting between the first limiting groove 122 and the second limiting rib 352 can prevent the rotating tube 351 from rotating. The limiting between the first limiting rib 313 and the second limiting groove 353 can prevent the rotating shell 31 from rotating, thereby preventing the adjustable support rod from rotating. The movement of rod 32 and clamping part 33 realizes the function of fixing the position of adjustable support rod 32 and clamping part 33. When it is necessary to readjust the angle or position of adjustable support rod 32 and clamping part 33, the operator can push the adjustable transmission gear 35 until the second limiting rib 352 on the rotating tube 351 is completely disengaged from the first limiting groove 122 in the fixed tube 121. At this time, the adjustable transmission gear 35 just moves to the position of meshing with the drive gear 36, which makes it convenient for the operator to adjust the angle of adjustable support rod 32 according to the inclination angle of the slope, thereby making the device more stable and having the characteristics of easy adjustment and strong practicality.

[0037] Please see Earth 3 and Figure 4As one embodiment of this application, the adjustable support rod 32 is connected to a first fixing block 321, a pin 324, and a rotating shaft 325. The first fixing block 321 is connected to a rotating wheel 323 through a fixing shaft 322. The rotating wheel 323 is rotatably connected to a circular guide rail 311. A fixing rod 17 is also fixedly connected to the support frame 12, and the rotating shaft 325 is rotatably connected to the fixing rod 17.

[0038] In the above scheme, the rotating housing 31, which performs eccentric rotational motion, can adjust the position of the rotating wheel 323 (which moves in a straight line relative to the center of the rotating housing 3), thereby realizing the function of driving the adjustable support rod 32 to rotate around the rotating shaft 325.

[0039] Please see Figure 1 , Figure 5 As one embodiment of this application, the clamping part 33 includes a sliding plate 331, a second fixing block 332, a guide tube 333, and a first spring 334. The second fixing block 332 is installed on one end of the sliding plate 331 near the adjustable support rod 32. A first groove 336 is formed on the surface of the second fixing block 332. The pin 324 is slidably connected in the first groove 336. A guide tube 333 is installed on the other end of the sliding plate 331. The sliding plate 331 is slidably connected in a through hole formed on the surface of the fixing plate 16. A first spring 334 is provided between the guide tube 333 and the fixing plate 16. The first spring 334 is sleeved on the sliding plate 331. A first clearance hole 335 is formed on the surface of the sliding plate 331.

[0040] In the above scheme, the rotating adjustable support rod 32 can slide in the first slide groove 336 through the pin 324, which can drive the slide plate 331 to make a linear movement closer to or away from the soil sampling mechanism 2. The guide tube 333 on the slide plate 331 is designed as a square tube, and the surface of the square tube is in contact with the surface of the soil sampling mechanism 2, which plays a supporting and limiting role. The first spring 334 plays a buffering and shock absorption role, which can reduce the impact force from the guide tube 333 on the soil sampling mechanism 2 under violent shaking.

[0041] Please see Figure 1 , Figure 5 , Figure 6 and Figure 7 As one embodiment of this application, the support part 34 includes a first slide rod 341, a support plate 342, a second spring 343, and a slider 344. The first slide rod 341 is movably sleeved in the guide tube 333. The support plate 342 is installed at the end of the first slide rod 341. The slider 344 is connected to the surface of the support plate 342. The second spring 343 is connected between the support plate 342 and the guide tube 333 and is sleeved on the first slide rod 341.

[0042] In the above scheme, when the soil sampling frame 21 descends, it can drive the first slide rod 341 to slide in the guide tube 333 by squeezing the support plate 342. The support plate 342 plays a supporting role for the soil sampling mechanism 2, and the second spring 343 plays a shock absorption and buffering role. The slider 344 on the support plate 342 can slide in the second slide groove on the side wall of the soil sampling frame 21. The slider 344 and the second slide groove are designed as a dovetail block and a dovetail groove, respectively. When the soil sampling frame 21 rises, the support plate 342 and the first slide rod 341 can rise together through the cooperation design between the dovetail block and the dovetail groove. Looking at the entire soil sampling process of the soil sampling mechanism 2, the soil sampling frame 21 can prevent the soil sampling frame 21 from tilting, and the support part 34 can support it along the movement direction of the soil sampling frame 21, thereby ensuring the stability and firmness of the soil sampling mechanism 2.

[0043] Please see Figure 1 As one embodiment of this application, the soil sampling mechanism 2 includes a soil sampling frame 21, a drive motor 22, a soil sampling auger 23, a telescopic member 24, and a lifting plate 25. One end of the telescopic member 24 is fixedly connected to the fixed frame 11, and the other end of the telescopic member 24 is connected to the lifting plate 25. Both ends of the lifting plate 25 are slidably connected to the side wall of the support frame 12. The soil sampling frame 21 is installed on the lifting plate 25, and the soil sampling frame 21 is also slidably connected to the fixed frame 11. The soil sampling auger 23 is installed inside the soil sampling frame 21. The soil sampling auger 23 is connected to the drive motor 22 through a drive shaft. The side wall of the soil sampling frame 21 is also provided with a second sliding groove. The slider 344 is slidably connected in the second sliding groove. The side wall of the soil sampling frame 21 is also fitted and connected to the side wall of the guide tube 333.

[0044] In the above scheme, the soil extracted by the soil extraction auger 23 enters the soil extraction frame 21, which serves to collect the soil. The telescopic component 24 is designed as a hydraulic rod, which is also located in the first clearance hole 335 on the surface of the slide plate 331.

[0045] When this application is used, if the terrain or location for soil extraction is a slope, the device is first moved to the slope surface using the adjustable roller 15. Then, the threaded rod 13 is driven into the slope by rotating the knob 131. Next, the adjustable roller 15 is rotated to move it away from the slope surface. Immediately afterwards, the drive gear 36 is rotated to drive the adjustable transmission gear 35 and the eccentric rod 312 to rotate. The rotating eccentric rod 312 can drive the rotating housing 31 to perform an eccentric rotational motion. The rotating housing 31, which performs an eccentric rotational motion, can adjust the position of the rotating wheel 323 (which is a linear motion relative to the center of the rotating housing 3), thereby realizing the function of driving the adjustable support rod 32 to rotate around the rotating shaft 325. The rotating adjustable support rod 32 slides in the first slide groove 336 through the pin 324, which can drive the slide plate 331 to perform a linear motion closer to or further away from the soil extraction mechanism 2. The guide tube 333 on the slide plate 331 is designed to be square. The surface of the square tube is in contact with the surface of the soil sampling mechanism 2, which serves as support and limit. When the soil sampling frame 21 descends, it can drive the first slide rod 341 to slide in the guide tube 333 by squeezing the support plate 342. The support plate 342 supports the soil sampling mechanism 2, and the second spring 343 acts as shock absorber. The slider 344 on the support plate 342 can slide in the second slide groove on the side wall of the soil sampling frame 21. The slider 344 and the second slide groove are designed as a dovetail block and a dovetail groove, respectively. When the soil sampling frame 21 rises, the support plate 342 and the first slide rod 341 can rise together through the cooperation design between the dovetail block and the dovetail groove. Throughout the soil sampling process of the soil sampling mechanism 2, the soil sampling frame 21 can prevent the soil sampling frame 21 from tilting, and the support part 34 can support it along the movement direction of the soil sampling frame 21, thereby ensuring the stability and firmness of the soil sampling mechanism 2.

[0046] After the angle of the adjustable support rod 32 is adjusted, the operator pulls the push-pull ring 354 to drive the adjustable transmission gear 35 to move along the axis of the rotating tube 351 until the second limiting rib 352 on the rotating tube 351 is fully inserted into the first limiting groove 122 in the fixed tube 121. Since the fixed tube 121 is fixed, the limiting between the first limiting groove 122 and the second limiting rib 352 can prevent the rotating tube 351 from rotating. The limiting between the first limiting rib 313 and the second limiting groove 353 can prevent the rotating housing 31 from rotating. This prevents the adjustable support rod 32 and clamping part 33 from moving, thus fixing their positions. When the angle or position of the adjustable support rod 32 and clamping part 33 needs to be adjusted again, the operator can push the adjustable transmission gear 35 until the second limiting rib 352 on the rotating tube 351 is completely disengaged from the first limiting groove 122 in the fixed tube 121. At this time, the adjustable transmission gear 35 moves to the position where it meshes with the drive gear 36, making it easy for the operator to adjust the angle of the adjustable support rod 32 according to the slope's inclination angle.

[0047] In summary, the rotating drive gear 36 drives the adjustable transmission gear 35 to rotate, which in turn drives the rotating housing 31 to rotate. The rotating housing 31 can then drive the adjustable support rod 32 to rotate at a certain angle. The adjustable support rod 32 is designed as a telescopic rod, and by adjusting its length, it can be inserted into the slope, thereby making the device more stable and preventing tilting. At the same time, the rotating adjustable support rod 32 can also drive the clamping part 33 to move linearly. The clamping part 33 is symmetrically distributed on both sides of the soil extraction mechanism 2, and the support part 34 on the clamping part 33 can also support the soil extraction mechanism 2. The design of the clamping part 33 and the support part 34 working together can prevent the tilted soil extraction mechanism 2 from shaking or breaking or deforming due to uneven force during operation, thus solving the problem that existing rapid soil extraction devices for civil engineering cannot work stably on sloping terrain.
