[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figures 1-8 The present invention provides a technical solution: an engineering foundation detection sampling device includes a carrier 1, an L-shaped frame 2 is vertically installed on the top of the carrier 1, and a height adjustment component is provided on the L-shaped frame 2, a lifting plate 6 is provided above the carrier 1, and a first driving component, a fixing component and a second driving component are provided on the lifting plate 6, a connecting plate 11 is provided below the lifting plate 6, and a first arc-shaped sampling body 9 is vertically installed at both ends of the connecting plate 11, a U-shaped frame 13 is vertically installed on the top of the connecting plate 11, and a blanking component and a pushing component are provided on the U-shaped frame 13, and a circular hole 38 is opened on the top of the carrier 1;

[0038] The blanking assembly includes a second arc-shaped sampling body 10, a lifting thread plate 12 and a second screw rod 14. The second screw rod 14 is vertically penetrated through the top of the connecting plate 11, and the second screw rod 14 is rotatably connected to the connecting plate 11. The outer side of the second screw rod 14 is threadedly engaged with the lifting thread plate 12, and the lifting thread plate 12 is located above the connecting plate 11. The second arc-shaped sampling body 10 is vertically installed at both ends of the lifting thread plate 12, and convex bars 28 are vertically installed on both sides of the second arc-shaped sampling body 10. Concave grooves 27 are vertically opened on both sides of the two first arc-shaped sampling bodies 9, and convex bars 28 are slidably inserted into the concave grooves 27.

[0039] Specifically, when it is necessary to open the first curved sampling body 9 and the second curved sampling body 10, the second screw rod 14 is driven to rotate, and the rotating second screw rod 14 drives the lifting threaded plate 12 to move up, and the lifting threaded plate 12 drives the two second curved sampling bodies 10 to move up between the first curved sampling body 9, thereby reducing the restriction of the first curved sampling body 9 and the second curved sampling body 10 on the sample. During the upward movement of the second curved sampling body 10, the convex bar 28 installed on the second curved sampling body 10 slides in the concave groove 27, thereby ensuring the stability of the cooperation between the second curved sampling body 10 and the first curved sampling body 9, facilitating the rapid collection of samples between the first curved sampling body 9 and the second curved sampling body 10, and improving the convenience of sampling. The cooperation between the various components of the device is controlled by the worker using the control panel.

[0040] Furthermore, the pusher assembly includes a thread groove 32, a third screw rod 25 and a push plate 24. The through end of the second screw rod 14 is provided with a thread groove 32, and the third screw rod 25 is engaged with the inner thread of the thread groove 32. The push plate 24 is installed at the bottom of the third screw rod 25, and the push plate 24 is located between the two first arc-shaped sampling bodies 9.

[0041] Specifically, the third screw rod 25 threadedly installed in the thread groove 32 opened at the bottom of the second screw rod 14 moves downward, and the downward-moving third screw rod 25 can drive the push plate 24 to move downward between the two first arc-shaped sampling bodies 9, and then the sample between the first arc-shaped sampling bodies 9 can be slowly pushed out, further improving the sampling efficiency. The cooperation between the second screw rod 14 and the third screw rod 25 is the reverse cooperation of the screw rod mechanism, that is, through the threaded cooperation of the nut and the screw rod, the rotational motion of the nut is converted into the linear motion of the screw rod.

[0042] Furthermore, a second guide rod 26 is vertically symmetrically installed on the top of the push plate 24, and the top of the second guide rod 26 is slidably penetrated by a connecting plate 11;

[0043] Specifically, during the up and down movement of the push plate 24, the second guide rod 26 vertically symmetrically installed on the top of the push plate 24 slides through the connecting plate 11, thereby improving the stability of the up and down movement of the push plate 24 and guiding the downwardly moving push plate 24.

[0044] Furthermore, the bottom of the lifting threaded plate 12 is symmetrically installed with a limit column 29, and both sides of the connecting plate 11 are installed with a limit plate 30, and the two limit plates 30 are penetrated by a limit hole 31, and the limit column 29 is slidably inserted into the limit hole 31;

[0045] Specifically, when the lifting thread plate 12 moves down to a position close to the connecting plate 11, a tubular shape is formed between the second arc-shaped sampling body 10 and the first arc-shaped sampling body 9. The limiting column 29 installed at the bottom of the lifting thread plate 12 is inserted into the limiting plate 30 installed on the connecting plate 11, which can improve the stability between the connecting plate 11 and the lifting thread plate 12, thereby ensuring the stability between the first arc-shaped sampling body 9 and the second arc-shaped sampling body 10, and ensuring that the first arc-shaped sampling body 9 and the second arc-shaped sampling body 10 can perform sampling normally and stably.

[0046] Furthermore, the height adjustment assembly includes a first motor 3, a first screw rod 4 and a threaded block 5. The first screw rod 4 is vertically rotatably installed in the L-shaped frame 2. The outer side of the first screw rod 4 is threadedly engaged with the threaded block 5. A lifting plate 6 is installed on the outer side of the threaded block 5. The first motor 3 is installed on the top of the L-shaped frame 2, and the first motor 3 is used to drive the first screw rod 4 to rotate. Third guide rods 35 are vertically symmetrically installed on the top of the carrier 1, and the third guide rods 35 are all slidably penetrated by the lifting plate 6.

[0047] Specifically, when sampling the soil, the first motor 3 is driven to drive the first screw rod 4 to rotate, and the rotating first screw rod 4 drives the threaded block 5 to move downward. During this process, the second motor 8 is driven to drive the U-shaped frame 13 to rotate, and the rotating U-shaped frame 13 drives the connecting plate 11 to rotate, and the rotating connecting plate 11 drives the two first arc-shaped sampling bodies 9 to rotate, and the rotating two first arc-shaped sampling bodies 9 drive the second arc-shaped sampling body 10 to rotate, thereby realizing soil sampling. At the same time, the third guide rod guides the movement of the lifting plate to ensure its movement stability. The setting of the guide groove and the guide block further limits the rotation of the threaded block to ensure that it can only move up and down.

[0048] Furthermore, the first drive assembly includes a second motor 8, a stabilizing frame 33 and a bearing 34. The second motor 8 is installed on the top of the lifting plate 6, and the output end of the second motor 8 passes through the lifting plate 6. The output end of the second motor 8 is connected to the top of the U-shaped frame 13. The output end of the second motor 8 is sleeved with a bearing 34, and the stabilizing frame 33 is installed on the outside of the bearing 34. The top of the stabilizing frame 33 is installed to the bottom of the lifting plate 6.

[0049] Specifically, when the tubular drill bit formed by the first arc-shaped sampling body 9 and the second arc-shaped sampling body 10 is rotated, the U-shaped frame 13 is driven to rotate by driving the second motor 8, and the first arc-shaped sampling body 9 and the second arc-shaped sampling body 10 can be driven by the rotating U-shaped frame 13. During the rotation of the second motor 8, a bearing 34 is sleeved on the output end of the second motor 8, and a stabilizing frame 33 is installed on the outside of the bearing 34. The stabilizing frame 33 is fixedly installed to the bottom of the lifting plate 6, thereby ensuring the stability of the rotation of the output end of the second motor 8, improving the stability of the rotation of the U-shaped frame 13, and ensuring the stability of sampling. The second motor 8 drives the U-shaped frame 13 to rotate, and then drives the sampling component to rotate. During the sampling process, the output shaft of the rotating second motor 8 will vibrate, and the stability of the rotation of the output end of the second motor 8 is ensured by the setting of the bearing and the stabilizing frame.

[0050] Furthermore, the second drive assembly includes a first gear 15, a first electric push rod 16, a third motor 17, and a second gear 18. The first gear 15 is installed on the outside of the second screw rod 14 and is located in the U-shaped frame 13. The first gear 15 and the second gear 18 are meshed with each other. The first electric push rod 16 is vertically installed at the bottom of the lifting plate 6, and the output end of the first electric push rod 16 is installed with the third motor 17. The output end of the third motor 17 is installed with the second gear 18. The bottom of the lifting plate 6 is vertically symmetrically installed with first guide rods 19, and the bottoms of the two first guide rods 19 are both slidably penetrated by guide plates 20, and the guide plates 20 are both mounted to the outer walls of the third motor 17.

[0051] Specifically, when the second screw rod 14 needs to be driven, the first arc-shaped sampling body 9 and the second arc-shaped sampling body 10 are raised to the top position of the carrier 1, and then the first electric push rod 16 is started to drive the third motor 17 and the second gear 18 to move downward. At the same time, the third motor 17 is started to drive the second gear 18 to rotate slowly, and the second gear 18 can be moved down to a position where it engages with the first gear 15. The rotating second gear 18 drives the first gear 15 to rotate, and then drives the second screw rod 14 to rotate, providing power for the second screw rod 14.

[0052] Furthermore, the fixing assembly includes a second electric push rod 21, an arc-shaped clamping body 22 and a roughing body 23. The roughing body 23 is provided below the lifting plate 6. Mounting seats 7 are installed on both sides of the lifting plate 6, and the second electric push rod 21 is installed at the bottom of each mounting seat 7. The arc-shaped clamping body 22 is installed on the side where the output ends of the second electric push rod 21 are close to each other, and the arc-shaped clamping body 22 is used to fix the roughing body 23.

[0053] Specifically, when taking out the sample in the sampling tube, the sampling tube is raised to a certain height, and then the second electric push rod 21 is started to drive the arc-shaped clamping bodies 22 to approach each other. The rough body 23 can be clamped and fixed by the two arc-shaped clamping bodies 22 approaching each other, thereby fixing the output end of the second motor 8, thereby ensuring that the U-shaped frame 13 is in a fixed rotation, preventing the sampling tube from rotating during the sampling process and affecting the collection of the sample.

[0054] Furthermore, a guide groove 36 is vertically opened on the inner wall of the L-shaped frame 2 , and a guide block 37 is slidably installed in the guide groove 36 , and the guide block 37 is fixedly connected to the threaded block 5 .

[0055] Working principle: When using the engineering foundation detection sampling device, when it is necessary to take out the sample inside the sampling tube formed between the first arc-shaped sampling body 9 and the second arc-shaped sampling body 10, the first electric push rod 16 is driven to drive the third motor 17 and the second gear 18 to move downward. At the same time, the third motor 17 is started to drive the second gear 18 to rotate slowly, and the second gear 18 can be moved down to a position engaged with the first gear 15. At this time, the second screw rod 14 is driven to rotate by the first gear 15, and the rotating second screw rod 14 drives the lifting thread plate 12 to move upward, thereby driving the second arc-shaped sampling bodies 10 installed at both ends of the lifting thread plate 12 to move upward relative to the first arc-shaped sampling body 9, and adjusting the first arc-shaped sampling body 9 and the second arc-shaped sampling body 10 to appropriate positions. At this time, the second curved sampling body 10 slidingly connected to the first curved sampling body 9 is opened, which is convenient for taking out the sample in the sampling tube. At the same time, the rotating second screw rod 14 drives the third screw rod 25 to move downward. A threaded groove 32 is provided at the bottom of the second screw rod 14, and the third screw rod 25 is engaged with the inner thread of the threaded groove 32. Since the second screw rod 14 is rotatably installed on the connecting plate 11, when the second screw rod 14 rotates, it drives the third screw rod 25 to move up and down. "The principle is that the rotational motion of the nut is converted into linear motion of the screw rod through the thread cooperation between the nut and the screw rod." The sample clamped between the first curved sampling bodies 9 can be slowly pushed out by the downward moving third screw rod 25.
