[0024] As shown in the Figure 1 to Figure 4 accompanying drawings:

[0025] The present utility model provides a device for taking soil samples in highway engineering construction, including a main cylinder body 1. A bearing 2 is fixedly installed inside the main cylinder body 1. A threaded cylinder 3 is fixedly installed inside the bearing 2. A threaded column 4 is threadedly connected inside the threaded cylinder 3. A connecting seat 13 is fixedly installed on the outer side of the top end of the threaded column 4. A smooth rod 12 is fixedly installed on one side of the main cylinder body 1. A connecting hole for slidably connecting with the smooth rod 12 is provided on the connecting seat 13. A cavity is provided inside the threaded column 4. A sampling tube 5 is slidably connected inside the cavity. An accommodating chamber for accommodating soil is provided inside the sampling tube 5, and through holes for allowing soil to pass through are provided at both ends of the sampling tube 5.

[0026] Among them, a plurality of connecting rods 9 are fixedly installed on the top side of the threaded cylinder 3. One ends of the plurality of connecting rods 9 are commonly fixedly installed with a rotating ring 10. The rotating ring 10 and the threaded cylinder 3 are coaxially arranged, facilitating the operator to rotate the threaded cylinder 3.

[0027] Among them, anti-slip lines one are provided on the outer side of the rotating ring 10, facilitating the operator to rotate the rotating ring 10.

[0028] Among them, two groups of pedals 11 are symmetrically and fixedly installed on the outer side of the main cylinder body 1 to prevent the main cylinder body 1 from rotating during the use of the sampling device.

[0029] Wherein, a soil-breaking blade 8 is fixedly installed at the bottom end of the threaded post 4 to reduce the resistance suffered by the threaded post 4 when moving in the soil.

[0030] Wherein, a threaded seat 6 is fixedly installed at the top end of the threaded post 4, and the inner diameter of the threaded seat 6 is equal to the outer diameter of the sampling tube 5.

[0031] Wherein, a threaded cover 7 is threadedly connected to the outside of the threaded seat 6. Anti-slip lines II are provided on the outside of the threaded cover 7. The inner side of the threaded cover 7 abuts against the sampling tube 5 to prevent the sampling tube 5 from falling off. A through hole for ventilation is provided at the top end of the threaded cover 7, so as to quickly discharge the air inside the sampling tube 5 to the outside during the soil sampling operation, which is beneficial to quick sampling.

[0032] Wherein, a soil-clearing brush 14 is fixedly installed at the bottom end of the threaded cylinder 3, so as to use the wire brush on one side of the soil-clearing brush 14 to brush off the soil adhering to the surface of the threaded post 4, prevent it from blocking and entering the threaded post 4, and cause a blocking phenomenon.

[0033] The working principle of this embodiment: When soil sampling is required, first stand on the pedal 11 and rotate the rotating ring 10. At this time, the rotating ring 10 drives the threaded cylinder 3 to rotate, and the threaded cylinder 3 drives the threaded post 4 to move. The threaded post 4 enters the soil through the soil-breaking blade 8, and the soil enters the sampling tube 5. When the sampling position is appropriate, rotate the rotating ring 10 in the reverse direction to drive the threaded post 4 and the sampling tube 5 away from the threaded cylinder 3, unscrew the threaded cover 7, and take out the sampling tube 5 to complete the soil sampling.

[0034] The embodiments of the present utility model are given for the purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.
