[0002] Geotechnical drilling sampling equipment is an auxiliary equipment for geotechnical drilling. Geotechnical sampling equipment is a device used to collect and extract the rock and soil on the surface of the soil in the natural environment, so that relevant personnel can analyze the composition of the soil based on the samples to determine whether the drilling area is suitable for construction, etc.;

[0003] In geotechnical engineering, sampling and analysis of rock and soil is an indispensable process. However, the existing rock and soil sampling is usually done by workers drilling holes and then sampling the drilled rock and soil. This method divides the operation into two steps.

[0008] The stratified sampling mechanism is arranged between the drilling body and the positioning frame, and the stratified sampling mechanism is used to control the drilling component to be in an ascending state and a descending state.

[0032] The sampling box 5 is equidistantly and slidably connected to the drilling body 1;

[0033] The stratified sampling mechanism 3 is arranged between the drilling body 1 and the positioning frame 2, and the stratified sampling mechanism 3 is used to control the drilling assembly 4 to be in an ascending state and a descending state. When the drilling assembly 4 is in an ascending state, the rock and soil samples collected are scraped into the sampling box 5 in layers;

[0034] The stratified sampling mechanism 3 includes a first motor 31 fixedly connected to the top of the positioning frame 2, a threaded rod 32 fixedly connected to the output end of the first motor 31, a moving platform 33 threadedly connected to the outer surface of the threaded rod 32, and the moving platform 33 is slidably connected to the positioning frame 2;

[0035] The stratified sampling mechanism 3 also includes a sampling channel 37 opened in the drilling body 1, and the sampling channel 37 is provided with cleaning holes 34 and sample holes 38 at equal intervals. The inner wall of the drilling body 1 is fixedly connected with a sample guide arc plate 311 at equal intervals, and the sample guide arc plate 311 is located below the sample holes 38;

[0036] The layered sampling mechanism 3 also includes a rotating rod 36 rotatably connected to the drilling body 1, a belt 35 is transmission-connected between the rotating rod 36 and the threaded rod 32, a shifting rod 39 is fixedly connected to the outer surface of the rotating rod 36, and a scraping rod 310 is fixedly connected to the bottom end of the shifting rod 39;

[0037] The top surface of the sample guiding arc plate 311 is fixedly connected with a sample blocking plate 312, and the end of the shifting rod 39 away from the rotating rod 36 is fixedly connected with a sampling brush head 313;

[0038] The layered sampling mechanism 3 also includes an airbag ball 314 fixedly connected to the drilling body 1, and the airbag ball 314 and the shifting rod 39 are located at the same horizontal plane, one end of the airbag ball 314 is fixedly connected to an air guide tube 315, and the end of the air guide tube 315 away from the airbag ball 314 is fixedly connected to a gas gathering port 316;

[0039] The drilling assembly 4 includes a second motor 41 fixedly connected to the top of the moving platform 33, the output end of the second motor 41 is fixedly connected to a rotating shaft 42, the bottom end of the rotating shaft 42 is fixedly connected to a drill bit 44, and the outer surface of the rotating shaft 42 is fixedly connected to a spiral scraper 43;

[0040] The above scheme is adopted: through the coordinated use of the shifting rod 39 and the arrangement of sample holes 38 and other structures, the threaded rod 32 can be used to rotate clockwise, and the positioning frame 2 can limit the movable platform 33, so that the movable platform 33 carries the rotating shaft 42 to move upward, and cooperates with the rotation of the rotating shaft 42, so that the carried rock and soil samples are carried upward into the sampling channel 37. At the same time, the belt 35 is linked to the rotating rod 36 to rotate, so that the shifting rod 39 rotates to shift the rock and soil samples entering the sampling channel 37, and the rock and soil samples are pushed into the sampling box 5, which is beneficial to the device for rock and soil drilling sampling, and can also collect and sample the collected rock and soil samples, thereby improving the drilling sampling efficiency of the device;

[0041] In addition, by using the airbag ball 314 in conjunction with the air guide tube 315 and other structures, the rock and soil samples in the sampling channel 37 can be shifted by rotating the shifting rod 39, and the airbag ball 314 can be squeezed intermittently, so that the airflow in the airbag ball 314 is discharged into the sampling channel 37 through the air guide tube 315 and the air gathering port 316, thereby further improving the sampling and collection efficiency of the rock and soil samples and cleaning the sampling channel 37;

[0042] Among them: the arrangement of the scraping rod 310, the sample blocking plate 312 and the sample guiding arc plate 311 can utilize the sample guiding arc plate 311 to guide the rock and soil samples scraped out of the sample holes 38, making it easier for them to enter the sampling box 5 for collection, and the scraping rod 310 follows the rotation of the shifting rod 39 and cooperates with the sample blocking plate 312 to block the rock and soil samples to prevent the rock and soil samples from being retained in the sample guiding arc plate 311.

[0043] The working principle and use process of the present invention:

[0044] In order to facilitate the description and understanding of this work process, the drilling state and sampling state are mainly used to describe and explain:

[0045] In the drilling state: the staff controls the first motor 31 to rotate the threaded rod 32 counterclockwise by operating the control panel, and controls the second motor 41 to rotate the rotating shaft 42. The threaded rod 32 rotates counterclockwise, and cooperates with the positioning frame 2 to limit the moving platform 33, so that the moving platform 33 moves downward with the rotating shaft 42, thereby making the rotating shaft 42 and the drill bit 44 rotate and move downward to complete the drilling of the rock and soil;

[0046] In the sampling state: the above working process is reversed to control the first motor 31 to make the threaded rod 32 rotate clockwise, so that the movable platform 33 carries the rotating shaft 42 to move upward, and the spiral scraper 43 fixed on the outer surface of the rotating shaft 42 carries the drilled rock and soil sample into the sampling channel 37. At the same time, the rotation of the threaded rod 32 is linked to the rotation of the rotating rod 36 through the belt 35, so that the shifting rod 39 rotates to shift the rock and soil sample entering the sampling channel 37, prompting the rock and soil sample to be shifted to the sample guide arc plate 311, and the sample guide arc plate 311 guides the rock and soil sample into the sampling box 5. While the shifting rod 39 rotates, the airbag ball 314 is intermittently squeezed, so that the airflow in the airbag ball 314 is discharged into the sampling channel 37 through the air guide tube 315 and the air gathering port 316, so as to further improve the sampling and collection efficiency of the rock and soil samples and clean the sampling channel 37.
