[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please refer to Figure 1-6 As shown, this utility model provides a soil surveying device for engineering measurement, including a support 1. The top of the support 1 is provided with a top plate 5. A hydraulic cylinder 8 is installed on the top of the top plate 5. One end of the hydraulic cylinder 8 extends to the bottom of the top plate 5 and is connected to a connecting frame 9. A lifting plate 10 is connected to the bottom of the connecting frame 9. A drill cylinder 11 is rotatably connected to one end of the lifting plate 10. A drill bit 12 is installed at the bottom end of the drill cylinder 11. A drive mechanism is provided on one side of the drill cylinder 11 to facilitate its rotation. One end of the drill cylinder 11 passes through the interior of the support 1 and is slidably connected to it. A sampling mechanism is provided on the inner side of the drill cylinder 11 to facilitate soil layer sampling.

[0023] Specifically, during operation, the support frame 1 provides stable support, and the hydraulic cylinder 8 on the top plate 5 can drive the connecting frame 9 and the lifting plate 10 to rise and fall, thereby driving the drill barrel 11 and the drill bit 12 to move down. The drive mechanism can drive the drill barrel 11 to rotate so that the drill bit 12 can drill into the soil layer. The sampling mechanism inside the drill barrel 11 can perform layered sampling of soil layers at different depths, realizing efficient drilling and accurate sampling of soil layers. Thus, through the above structure, the device can drill efficiently and sample accurately, improving the efficiency of soil layer survey and data reliability.

[0024] The drive mechanism includes a drive motor 21. A driven gear 19 is sleeved on the outer ring of the drill barrel 11. The driven gear 19 meshes with a drive gear 20. The drive gear 20 is rotatably connected to the inner side of the connecting frame 9. The bottom of the lifting plate 10 is located on one side of the drill barrel 11 and the drive motor 21 is installed. The output end of the drive motor 21 passes through the interior of the lifting plate 10 and is connected to the drive gear 20. When driven, the drive motor 21 at the bottom of the lifting plate 10 starts, and its output end passes through the lifting plate 10, which can drive the drive gear 20 inside the connecting frame 9 to rotate. The drive gear 20 meshes with the driven gear 19 sleeved on the outer ring of the drill barrel 11, thereby driving the driven gear 19 and the drill barrel 11 to rotate on the lifting plate 10, providing rotational power for the drill bit 12 to drill into the soil layer. Thus, the drilling efficiency and stability of the soil layer are improved by this design.

[0025] Among them, a limiting rod 6 is provided between the support 1 and the top plate 5. The limiting rod 6 is slidably connected to the lifting plate 10 near the other end. The outer wall of the limiting rod 6 is provided with a scale line 7 along the length direction. The sliding connection between the limiting rod 6 and the lifting plate 10 can limit its lifting trajectory to ensure stability. The scale line 7 on the outer wall makes it easy to intuitively grasp the drilling depth of the drill barrel 11, and improve the drilling accuracy and operation stability.

[0026] The sampling mechanism includes a sampling rod 13, which is nested inside the drill barrel 11. A handle 18 is installed at the top of the sampling rod 13. A threaded connecting sleeve 17, threadedly connected to the sampling rod 13, is located at the top of the drill barrel 11. Three sets of collection troughs 14 are formed on the side of the sampling rod 13 from top to bottom. Three sets of sampling ports 15 are correspondingly formed on the side of the drill barrel 11. A discharge port 16, adapted to the collection troughs 14, is located near the end of the other side of the drill barrel 11. The bottom of the collection troughs 14 is sloped. During sampling, when the sampling rod 13 is tightened with the threaded connecting sleeve 17, the collection troughs 14 can be offset from the sampling ports 15, facilitating the drill barrel 11 to penetrate deeper into the soil layer and reach the designated location. After placement, by rotating the handle 18, the sampling rod 13 can be rotated, and the three sets of collection troughs 14 are aligned with the three sets of sampling ports 15 respectively. At this time, the soil sample can enter the corresponding collection trough 14 through the three sets of sampling ports 15. After sampling is completed, continue to rotate the sampling rod 13 to make the collection trough 14 and the sampling port 15 staggered, thus completing the closure. Finally, unscrew the sampling rod 13 and lift the sampling rod 13 through the handle 18. When the three sets of collection troughs 14 pass through the discharge port 16 on the other side of the drill barrel 11 in sequence, the layered soil samples in each collection trough 14 can be taken out. Thus, by setting it up, the accurate collection and anti-mixing of layered soil samples can be achieved, improving the sampling reliability.

[0027] The bracket 1 has four sets of legs 2 installed at its bottom. Each set of legs 2 has a tapered plug rod 3 at its bottom. Two sets of handles 4 are installed on one side of the bracket 1. The tapered plug rods 3 at the bottom of the four sets of legs 2 can enhance the stability of the bracket 1. The two sets of handles 4 facilitate handling and improve the ease of use and safety of operation of the device.

[0028] Working principle: First, the drive motor 21 is started. Its output end passes through the lifting plate 10, which drives the drive gear 20 inside the connecting frame 9 to rotate. The drive gear 20 meshes with the driven gear 19 sleeved on the outer ring of the drill barrel 11, thereby driving the driven gear 19 and the drill barrel 11 to rotate on the lifting plate 10, providing rotational power for the drill bit 12 to drill into the soil. Then, the hydraulic cylinder 8 is started, which drives the connecting frame 9 and the lifting plate 10 to move downward, thereby driving the drill barrel 11 and the drill bit 12 to drill into the soil. The lifting plate 10 slides along the limit rod 6, and the drilling depth can be observed through the scale line 7. After specifying the depth, by rotating the handle 18, the sampling rod 13 can be rotated, and the three sets of collection troughs 14 can be aligned with the three sets of sampling ports 15 respectively. At this time, the soil sample can enter the corresponding collection trough 14 through the three sets of sampling ports 15. After sampling is completed, continue to rotate the sampling rod 13 to make the collection trough 14 and the sampling port 15 staggered, thus completing the closure. Finally, unscrew the sampling rod 13 and lift the sampling rod 13 through the handle 18. When the three sets of collection troughs 14 pass through the discharge port 16 on the other side of the drill barrel 11 in sequence, the layered soil samples in each collection trough 14 can be taken out, thus completing the entire operation process.
