Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] During the use of the road, the road surface will gradually age due to factors such as long-term bearing of traffic loads, climate change, and environmental erosion, and problems such as cracks, settlements, and deformations will occur. Through regular inspections, these problems can be discovered and evaluated in a timely manner, and corresponding repair measures can be taken to extend the service life of the road, improve traffic safety, and reduce maintenance costs; the introduction of the soil sampling device provides a simple, rapid, and non-destructive way for road surface inspection.

This device is usually equipped with precise depth control and sampling mechanisms, which can ensure the integrity and representativeness of the samples and provide reliable materials for laboratory analysis.

[0027] Embodiment 1:

[0028] Based on the technical defects of low sampling efficiency and great damage to the road surface existing in the prior art, please refer to Figures 1-4, a soil sampling device with a spiral transmission mechanism provided by the utility model can continuously send the soil sample upward, and can meet the sampling volume requirement at one time. The whole soil sampling process solves the problems of low traditional soil sampling efficiency and great damage to the road surface. Moreover, the device has a compact overall structure and high working efficiency, and has the advantages suitable for modern road construction. The device includes a frame 1, an outer cylinder 2 is sleeved on the frame 1, a rotary motor 3 is installed at the top of the outer cylinder 2, a middle shaft 4 rotatably arranged inside the outer cylinder 2 is fixedly connected to the output shaft of the rotary motor 3, an alloy drill bit 41 is installed at the bottom of the middle shaft 4, a feeding auger 5 is fixedly arranged on the outer wall of the middle shaft 4, the middle shaft 4 is in transmission connection with an inner cylinder 7 through a transmission mechanism 6, the inner cylinder 7 is rotatably connected inside the outer cylinder 2, and a plurality of groups of equally spaced cutting blades 8 are installed at the bottom of the inner cylinder 7; during use, the rotary motor 3 is used to drive the middle shaft 4 to rotate, the middle shaft 4 drives the alloy drill bit 41 and the feeding auger 5 to rotate, the alloy drill bit 41 is used for drilling soil, and then the soil sample is conveyed upward along with the feeding auger 5.

[0029] To facilitate the control of the overall descent, two lifting mechanisms 9 for controlling the vertical movement of the outer cylinder 2 are also installed on the frame 1, and the two lifting mechanisms 9 are symmetrically distributed on the outside of the outer cylinder 2; through the setting of the lifting mechanism 9, the whole can be driven to move downward and carry out soil sampling work.

[0030] To obtain an accurate soil sample volume, a weighing mechanism 10 for detecting the weight of the soil sample is also installed on the frame 1; the weighing mechanism 10 is used to weigh the taken soil sample.

[0031] To ensure that the soil sample can accurately fall into the sample basket 104 after being sent out, a discharge pipe 21 is inclinedly arranged on the outer wall of the outer cylinder 2, and the discharge pipe 21 is directly above the weighing mechanism 10; when the soil sample flows out of the discharge pipe 21, it can just fall into the sample basket 104 on the weighing mechanism 10.

[0032] To drive the inner cylinder 7 to rotate synchronously with the middle shaft 4, please refer to Figure 2 and Figure 3 , the transmission mechanism 6 includes a driving wheel 61 fixedly connected to the top of the middle shaft 4, the driving wheel 61 is in transmission connection with a driven wheel 63 located outside the outer cylinder 2 through a belt 62, the driven wheel 63 is fixedly connected to the top of a transmission shaft 64, the transmission shaft 64 is rotatably connected to the outer wall of the outer cylinder 2 through a bearing bracket 65, a rotating gear 66 is fixedly arranged at the bottom of the transmission shaft 64, and the rotating gear 66 meshes with a toothed ring 67 fixedly arranged on the outer wall of the inner cylinder 7; when the middle shaft 4 rotates, the transmission shaft 64 can be driven to rotate through the transmission of the driving wheel 61 and the driven wheel 63, and the inner cylinder 7 can be driven to rotate through the meshing of the rotating gear 66 and the toothed ring 67.

[0033] To ensure that the rotating gear 66 can mesh with the gear ring 67 smoothly, a communication hole 22 is provided on the outer wall of the outer cylinder 2 near the meshing position of the rotating gear 66 and the gear ring 67. In this way, the rotating gear 66 can be in a meshing state with the gear ring 67 through the communication hole 22.

[0034] To achieve the positioning of the sampling position, a pressure plate 23 is fixedly installed at the bottom of the outer cylinder 2. During sampling, the pressure plate 23 can be pressed at the sampling position to play a role in positioning and protecting the external roadbed.

[0035] To ensure the smooth progress of the sampling process, please refer to Figure 1 , the lifting mechanism 9 includes a lifting motor 91 installed on the frame 1. A lifting gear 92 is fixedly installed on the output shaft of the lifting motor 91. The lifting gear 92 meshes with a toothed plate 93 fixedly connected to the outer wall of the outer cylinder 2. During sampling, the lifting motor 91 drives the lifting gear 92 to rotate, and the meshing action between the lifting gear 92 and the toothed plate 93 drives the outer cylinder 2 to move up and down, so as to sample the soil sample deep in the ground.

[0036] To ensure that the soil sample can flow out of the discharge pipe 21 smoothly, a scraper 11 is fixedly installed inside the outer cylinder 2 near the discharge pipe 21. When the feeding auger 5 conveys the soil sample to the topmost part, under the action of the scraper 11, the soil sample is blocked and quickly flows into the discharge pipe 21.

[0037] Embodiment 2:

[0038] Too little sampling amount is likely to affect subsequent detection, and too much sampling amount is not easy to carry. Therefore, a suitable sampling amount is required. Furthermore, on the basis of Embodiment 1, please refer to Figure 1 and Figure 2 , the weighing mechanism 10 includes a weighing platform 101 installed on the frame 1. A plurality of weighing sensors 103 are embedded on the surface of the weighing platform 101 and a sample basket 104 is placed. A digital display screen 102 electrically connected to the weighing sensors 103 is installed on the side wall of the weighing platform 101. After the soil sample falls into the sample basket 104, under the action of the weighing sensors 103, the weight of the soil sample is displayed on the digital display screen 102 in real time, so as to facilitate the staff to view.

[0039] As can be seen from the above embodiments: during use, first, due to the provision of the lifting mechanism 9, the lifting motor 91 drives the lifting gear 92 to rotate. By the meshing action of the lifting gear 92 and the toothed plate 93, the outer cylinder 2 is driven to move up and down, so that the outer cylinder 2 contacts the sampling position. Then, the lifting mechanism 9 and the rotating motor 3 work synchronously. The lifting mechanism 9 can drive the whole to move downward and carry out soil sampling work. The rotating motor 3 drives the intermediate shaft 4 to rotate, and the intermediate shaft 4 drives the alloy drill bit 41 and the feeding auger 5 to rotate. The alloy drill bit 41 is used for drilling soil, and then the soil sample is conveyed upward along the feeding auger 5. During the soil sampling process, due to the action of the transmission mechanism 6, the rotation of the intermediate shaft 4 can drive the transmission shaft 64 to rotate through the transmission action of the driving wheel 61 and the driven wheel 63. The transmission shaft 64 drives the inner cylinder 7 to rotate through the meshing action of the rotating gear 66 and the toothed ring 67. The inner cylinder 7 drives the cutting blade 8 to rotate, so as to cut the road surface to determine the radial profile of the soil sampling. When the soil sample falls onto the weighing mechanism 10 through the discharge pipe 21, the soil sample is weighed until it reaches the appropriate weight.
