DETAILED DESCRIPTION

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0019] A soil quality detection and sampling device for engineering investigation, such as Figure 1-Figure 5 As shown, it includes a frame 1, a handle 2, a moving mechanism, a fixed plate 5, a second motor 10, a drill rod 11, a sleeve 12 and a support mechanism. The left and right sides of the middle of the frame 1 are fixedly connected with the handle 2. The top of the frame 1 is connected to the moving mechanism. The moving mechanism drives the second motor 10, the drill rod 11 and the sleeve 12 to move downward. The upper part of the frame 1 is fixedly connected with the fixed plate 5. The second motor 10 is installed at the bottom of the moving mechanism. The second motor 10 is located below the fixed plate 5. The output shaft of the second motor 10 is fixed A drill rod 11 is fixedly connected, a threaded groove is opened on the outside of the drill rod 11, and a sleeve 12 is rotatably connected to the outside of the drill rod 11. The bottom of the drill rod 11 is conical, the tip of the cone faces downward, and the bottom of the sleeve 12 is higher than the bottom of the drill rod 11. When the drill rod 11 rotates, the soil can be moved upward along the threaded groove on the outside of the drill rod 11. The sleeve 12 can prevent the soil collected by the drill rod 11 from falling. A supporting mechanism is connected to the bottom of the frame 1, and the supporting mechanism can place the sampling device on the ground to facilitate soil sampling.

[0020] When it is necessary to test and sample the soil, hold the handle 2 with both hands, and then use the second motor 10 to drive the drill rod 11 to rotate. After the sampling is completed, the second motor 10, the drill rod 11 and the sleeve 12 are moved upward and reset through the moving mechanism. By using the moving mechanism and the second motor 10, the drill rod 11 can be drilled downward into the ground without manually rotating the drill rod 11, making soil sampling more convenient and quick, and improving the efficiency of soil testing and sampling.

[0021] like Figure 1 and Figure 2As shown, the moving mechanism includes a first threaded rod 3, a limit plate 4, a first motor 6, a second threaded rod 7, a gear 8 and a guide rod 9. The first threaded rod 3 is threadedly connected to the top of the frame 1. The top of the first threaded rod 3 is fixedly connected to the limit plate 4. The bottom of the first threaded rod 3 passes through the fixed plate 5, and the first threaded rod 3 is rotatably connected to the second motor 10. The first threaded rod 3 can drive the second motor 10, the drill rod 11 and the sleeve 12 to move up and down. The top of the fixed plate 5 is rotatably connected to the gear 8. The gear 8 is threadedly connected to the first threaded rod 3. When the second threaded rod 7 is continuously engaged with the gear 8 in both forward and reverse rotations, the gear 8 drives the first threaded rod 3 to move up and down. The first motor 6 is installed on the top of the movable limit plate 4, and the second threaded rod 7 is fixedly connected to the output shaft of the first motor 6. The gear 8 is engaged with the second threaded rod 7. A guide rod 9 is fixedly connected between the limit plate 4 and the second motor 10, and the guide rod 9 passes through the fixed plate 5 and the top of the frame 1. When the drill rod 11 rotates to take samples, the second threaded rod 7 is driven to rotate by the first motor 6. After the sampling is completed, the second threaded rod 7 is driven to reverse by the first motor 6. The second threaded rod 7 is engaged with the gear 8 to reverse the gear 8. The reverse gear 8 drives the first threaded rod 3 to move upward and reset. The first threaded rod 3 moves upward to drive the second motor 10, the drill rod 11 and the sleeve 12 to move upward and reset. The second motor 10, the drill rod 11 and the sleeve 12 are moved downward by the moving mechanism, so that the drill rod 11 and the sleeve 12 can collect soil at different depths, which is convenient for soil quality detection of soil at different depths.

[0022] like Figure 1 、 Figure 3 and Figure 4 As shown, the drill pipe 11 further includes a sliding cover 13. Three sampling slots 120 are formed on the front side of the sleeve 12. The sliding covers 13 are slidably connected to the sampling slots 120. When the sleeve 12 moves downward, the sliding cover 13 is closed. Sliding the sliding cover 13 upward to open the sampling slots 120 can expose the sampling slots 120. After the drill rod 11 and sleeve 12 are removed from the soil, the sliding cover 13 is slid upward to expose the soil in the sampling slots 120, thereby facilitating soil sampling at a specified depth and further facilitating soil quality testing. After sampling is completed, the sliding cover 13 is slid downward to return to its original position.

[0023] like Figure 1 and Figure 5As shown, the support mechanism includes a support plate 14, a support rod 15, and a support foot 17. Three support plates 14 are evenly distributed around the bottom of the frame 1. The side of the support plate 14 away from the frame 1 is connected to the support rod 15. The support rod 15 has a threaded groove on the outside. The support plate 14 is threadedly connected to the support rod 15. The support foot 17 is connected to the bottom of the support rod 15. By rotating the support rod 15, the support foot 17 contacts the ground, so that the sampling device remains in a vertical position. When the sampling device is placed on the ground using the support mechanism, by controlling the height of the support rod 15, the sampling device can be adapted to various uneven terrains, further facilitating soil sampling.

[0024] like Figure 1 and Figure 5 As shown, the support rods 15 further include a sphere 16, which is fixedly connected to the bottom of the sphere 16. The support rods 15 are rotatably connected to the support legs 17 via the sphere 16, allowing the support frame 17 to rotate at multiple angles, allowing the support mechanism to adapt to various slopes and further facilitate soil sampling. When the support legs 17 are in contact with the ground, the support legs 17 can rotate via the sphere 16 to adapt to the slope of the ground.

[0025] like Figure 1 As shown, the device further includes an anti-slip cover, which is fixedly connected to the handle 2 and has anti-slip grooves. When the handle 2 is grasped with both hands, the anti-slip cover can prevent the handle 2 from slipping and causing the sampling device to fall over, thereby avoiding accidents.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
