[0002] Geotechnical investigation is the process of investigating and studying rocks and soil in geological structures. The purpose is to understand the conditions of underground rocks and soils. It is widely used in civil engineering, geological engineering, etc. During the investigation process, it is necessary to open the soil at the corresponding location for sampling, and then conduct research and analysis after sampling. This solution specifically involves a soil opener for geotechnical investigation;

[0003] When using existing earth-moving drills for geotechnical investigation, the smoke and dust generated during earth-moving are easy to spread due to the relatively hard rock and soil, making it inconvenient to drill and collect samples, and it is not convenient to adjust the drilling depths. In addition, the drill is easy to slide and deviate during the drilling process, making it inconvenient to fix the whole device to the ground, which has a certain impact on actual use.

A lifting plate 10 is installed around the sleeve, and a motor 11 is installed in the center of the top of the lifting plate 10. A drill rod 12 is installed at the bottom end of the output shaft of the motor 11 and passes through the sampling box 8 and the bottom plate 1. Screw sleeves 13 are fixedly installed at the rear end of the upper and lower parts of the lifting plate 10. A screw rod 14 is movably installed passing through the top of the top plate 6 and the inside of the screw sleeve 13. A rocker 15 is fixedly installed on the top of the screw rod 14. A dustproof brush 16 is installed at the bottom of the sampling box 8 and on the periphery of the drill rod 12. A discharge trough 17 is provided inside the sampling box 8, and a collecting box 18 is movably installed inside the discharge trough 17.

[0023] In this embodiment, four support columns 5 are arranged in a matrix, and the drill rod 12 and the output shaft of the motor 11 are arranged to rotate synchronously. The motor 11 drives the drill rod 12 to rotate, so that the drill rod 12 drills the rock soil.

[0024] In this embodiment, the screw rod 14 passes through the interior of the screw sleeve 13 and is threadedly connected. The lifting plate 10 is slidable up and down through two guide rods 9. The screw rod 14 is used to slide the lifting plate 10 up and down to perform drilling at different depths.

[0025] In this embodiment, the collecting box 18 is located inside the discharge chute 17 and is slidable forward and backward, and the dust-proof brush 16 is located on the periphery of the drill rod 12 and is matched with each other. The drilled rock or soil is discharged through the discharge chute 17 and slides into the collecting box 18 for collection.

[0026] In this embodiment, the fixing mechanism 4 includes four fixing sleeves 19, and the four fixing sleeves 19 are respectively fixedly installed at the front and rear ends of the two sides of the base plate 1, and a plug rod 20 is movably installed through the top of each fixing sleeve 19, and a pedal 21 is fixedly installed between the tops of the two plug rods 20 on the same side of the two sides, and a fixing block 22 is installed at the bottom of the pedal 21, and a positioning bolt 23 is installed through the outer side of the fixing block 22, and two fixing plates 24 are installed between the two support columns 5 on the same side of the two sides, and screw holes 25 are opened through the outer side of the fixing plate 24. By sliding the plug rod 20, the plug rod 20 is inserted into the ground to fix the whole body and prevent displacement.

[0027] In this embodiment, the insertion rod 20 is inserted into the interior of the fixing sleeve 19 and is slidable up and down. The two insertion rods 20 on one side are slidably arranged synchronously through the pedal 21. The insertion rod 20 passes through the fixing sleeve 19 and is inserted into or removed from the ground, which is convenient for fixing the base plate 1 to the ground and for easy movement.

[0028] In this embodiment, the two pedals 21 are symmetrically arranged, and the inner end of the positioning bolt 23 is threadedly connected to the screw hole 25. The connection between the positioning bolt 23 and the screw hole 25 facilitates the fixing of the insertion rod 20 after sliding.

[0029] It should be noted that the utility model is a soil excavator for geotechnical investigation. When in use, the base plate 1 is first moved to a specified position by the universal wheel 2. When fixed, the positioning bolt 23 is rotated to disengage the positioning bolt 23 from the screw hole 25 at the upper end, and the insertion rod 20 is slid downward. The insertion rod 20 is inserted into the ground surface by stepping on the pedal 21, and the positioning bolt 23 is rotated to connect the positioning bolt 23 with the screw hole 25 at the lower end, so that the base plate 1 and the ground are fixed to each other, and soil excavation sampling is performed. When the drill rod 12 is rotated, the motor 11 is started to rotate the drill rod 12, and the shaking plate 15 is shaken to rotate the screw 14. The threaded connection between the screw 14 and the screw sleeve 13 drives the lifting plate 10 to slide downward, and drives the drill rod 12 to drill into the rock and soil. The rock and soil are drilled out by the rotation of the drill rod 12, and the dust diffusion is reduced by the dustproof brush 16. At the same time, the surface of the drill rod 12 is cleaned, and the drilled rock and soil are transported to the discharge trough 17 and slide into the collection box 18, and are collected by the collection box 18.
