The part of civil engineering involving rock, soil, underground and water is called geotechnical engineering. Geotechnical engineering investigation refers to the identification, analysis and evaluation of the geological and environmental characteristics and geotechnical engineering conditions of the target construction site according to the requirements of the construction project. Geotechnical investigation requires decentralized investigation of multiple sampling sites in the same area to obtain the underground rock and soil distribution status map of the target construction site, from which the natural conditions such as the topography, landform and hydrology of the underground of the construction area are analyzed to help the later construction planning.

[0003] The existing technology has the following shortcomings: the existing drilling device can only perform a single drilling operation when drilling rock and soil, and cannot conveniently perform soil sampling on the inner wall of the drilled hole. It is necessary to use a sampling and detection device to implement soil detection, which makes it impossible for staff to conveniently detect geology, affecting the efficiency of geotechnical engineering surveys.

[0030] The utility model provides Figure 1 The drilling device with sample collection function shown includes a fixing mechanism 1 and also includes:

[0031] The drilling mechanism 2 is arranged inside the fixing mechanism 1 and is used for drilling the soil or rock;

[0032] The sampling mechanism 3 is arranged at the bottom outer side of the drilling mechanism 2 and is used for sampling soil or rock.

[0033] In order to facilitate the drilling of rock and soil, Figure 2 and Figure 4 As shown, the drilling mechanism 2 includes an auger rod 201, which is arranged at the inner top of the fixing mechanism 1, a servo motor 202 is arranged on the top of the auger rod 201, an electric cylinder 204 is arranged on the bottom inner wall of the auger rod 201, a mounting frame 205 is fixedly installed on the output end of the electric cylinder 204, a drill bit 206 is fixedly installed on the bottom of the mounting frame 205, and the servo motor 202 works to make the auger rod 201 rotate, so that drilling operations can be performed on rock and soil.

[0034] In order to facilitate sampling, Figure 2 and Figure 5 As shown, the sampling mechanism 3 includes an electric rotating rod 301, which is rotatably installed on the inner top of the mounting frame 205. A rotating sleeve 302 is fixedly sleeved on the outer side of the electric rotating rod 301. Four traction plates 303 are rotatably installed on the outer side of the rotating sleeve 302. A sampling sleeve 305 is provided at one end of the traction plate 303 away from the rotating sleeve 302. The operation of the electric rotating rod 301 causes the rotating sleeve 302 to rotate, and then under the traction action of the four traction plates 303, the four sampling sleeves 305 can be driven to be inserted into the rock and soil on the inner wall of the hole, so that sampling can be conveniently performed.

[0035] In order to keep the drilling mechanism 2 stable during the drilling process, Figure 2 and Figure 3 As shown, the fixing mechanism 1 includes two fixing frames 101 and a mounting plate 105. The inner walls of the two fixing frames 101 are each provided with a movable groove 102. The outer walls of both ends of the mounting plate 105 are each fixedly provided with a movable seat 104. The inner wall of the movable groove 102 is movably connected to the outer wall of the adjacent movable seat 104. The movable groove 102 can limit the movement of the movable seat 104, so that the mounting plate 105 remains stable during the movement, thereby enabling the auger rod 201 to stably perform drilling operations on rock and soil.

[0036] In order to provide power for the drilling mechanism 2 to go deeper, Figure 2 and Figure 3 As shown, hydraulic cylinders 103 are fixedly installed on the top of the two fixed frames 101, and the output ends of the two hydraulic cylinders 103 pass through the top inner wall of the movable groove 102 and are fixedly connected to the top of the adjacent movable seat 104. The fixed frame 101 can install and fix the hydraulic cylinder 103. The operation of the hydraulic cylinder 103 enables the mounting plate 105 to move inside the two fixed frames 101, thereby allowing the drilling mechanism 2 to easily penetrate into the rock and soil.

[0037] In order to provide power for the rotation of the auger rod 201, Figure 2 As shown, the inner wall of the mounting plate 105 is rotatably connected to the top of the auger rod 201, and the top of the mounting plate 105 is fixedly connected to the servo motor 202. The servo motor 202 and the auger rod 201 are connected via an output shaft transmission. The mounting plate 105 can install and fix the servo motor 202. When the servo motor 202 works, the auger rod 201 rotates, thereby performing drilling operations on rock and soil.

[0038] In order to conveniently store the sampling mechanism 3, Figure 2 As shown, a storage groove 203 is provided on the bottom inner wall of the auger rod 201, and the top of the inner wall of the storage groove 203 is fixedly connected to the electric cylinder 204. The diameter of the storage groove 203 is larger than the diameter of the sampling mechanism 3 in the contracted state. The storage groove 203 can store the sampling mechanism 3 to prevent the collected samples from falling.

[0039] In order to make the sampling sleeve 305 stably extend or contract, Figure 2 and Figure 4-5 As shown, limiting grooves 207 are provided around the top of the drill bit 206, and sliders 306 are fixedly installed at the bottom of the four sampling sleeves 305. The inner wall of the limiting groove 207 is movably connected to the outer wall of the adjacent slider 306. A fixing seat 304 is fixedly installed at one end of the four sampling sleeves 305 close to the rotating sleeve plate 302. The top of the fixing seat 304 is rotatably connected to the adjacent traction plate 303. The rotational connection between the traction plate 303 and the fixing seat 304 can drive the sampling sleeve 305 to extend or contract. At the same time, the limiting groove 207 can limit the movement of the slider 306, so that the sampling sleeve 305 remains stable during the movement.

[0040] The specific implementation method is as follows: when drilling rock and soil, the servo motor 202 is operated to rotate the auger rod 201, and at the same time, the two hydraulic cylinders 103 can drive the movable seat 104 to move downward along the inner wall of the adjacent movable groove 102, so that the mounting plate 105 moves downward along the inner side of the two fixing frames 101, so that the auger rod 201 can penetrate into the rock and soil, and then the rock and soil can be drilled as the auger rod 201 penetrates. When drilling to a certain depth, the electric cylinder 204 can push the mounting frame 205 to extend downward from the inside of the storage groove 203, so that the sampling mechanism 3 can extend from the inside of the storage groove 203, and then the electric rotating rod 301 is operated to rotate the rotating sleeve plate 302, and then under the traction of the four traction plates 303, the sampling mechanism 3 can be pulled out of the storage groove 203. Under the action, the four sampling sleeves 305 extend toward the outside of the spiral drill rod 201, and at the same time, the limiting groove 207 can limit the movement of the slider 306, so that the four sampling sleeves 305 can be stably inserted into the inner wall of the drilled hole to perform rock and soil sampling operations. When the sampling is completed, the electric rotating rod 301 rotates in the opposite direction so that the sampling sleeve 305 can be retracted to a position close to the rotating sleeve plate 302, and then the sampling mechanism 3 can be stored in the storage groove 203 through the electric cylinder 204, and then as the two hydraulic cylinders 103 contract, the spiral drill rod 201 can be driven out of the hole, so that it is convenient for the staff to test the rock and soil samples. This embodiment specifically solves the problem in the prior art that it is not possible to conveniently sample and test the soil inside the rock and soil layer when drilling rock and soil.

[0041] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
