DETAILED DESCRIPTION

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] Example: A sampling device for geological engineering, such as Figures 1-7 As shown, the device includes a bracket 1, a controller 101, a base 2, an electric slide rail 3, an electric slider 4, a drive motor 5, a sampling cylinder 6, a retaining sleeve 7, a servo motor 8, a partition 9, a baffle 10, a support platform 11, a sampling box 12, a protrusion 13, a connector 14, and a connecting rod 15. The controller 101 is bolted to the middle of the bracket 1. The base 2 is fixed to the bottom of the bracket 1, and the bottom of the base 2 has several feet to prevent movement of the device. An electric slide rail 3 is installed on the front of the bracket 1, and an electric slider 4 is slidably connected to the electric slide rail 3. A drive motor 5 is fixed to the electric slider 4 and electrically connected to the controller 101. The bottom of the output shaft of the drive motor 5 is threaded to the sampling cylinder 6, which is made of metal and has a retaining sleeve 7 threaded to its bottom. A servo motor 8 is fixed to the upper part of the sampling cylinder 6 and electrically connected to the controller 101. A partition 9 is fixedly connected to the middle of the sampling cylinder 6. The partition 9 has a vertical groove for the output shaft of the servo motor 8 to rotate. Several baffles 10 are rotatably connected to the left outer wall of the sampling cylinder 6. The bottom of the baffles 10 is embedded with a magnet and has magnetic properties, so that it can attract the metal sampling cylinder 6. The left inner wall of the sampling cylinder 6 is longitudinally welded with the same number of support platforms 11 as the baffles 10. The support platforms 11 correspond to the baffles 10. Each support platform 11 is slidably connected with the same number of sampling boxes 12. The opening of the sampling boxes 12 is obliquely cut. The sides of the support platforms 11 are provided with blocks to restrict the sliding of the sampling boxes 12. The output shaft of the servo motor 8 is longitudinally fixed with the same number of protrusions 13 as the sampling boxes 12. The output shaft of the servo motor 8 is also fixed with the same number of connectors 14 as the protrusions 13. The bottom of the connectors 14 is rotatably connected with connecting rods 15. Each connecting rod 15 is rotatably connected to the top of the sampling box 12.

[0028] When using the device, first need to be placed on a flat surface, make sure it will not be tilted or moved due to uneven ground. When the soil needs to be sampled, the controller 101 starts the drive motor 5 and electric slide 4, electric slide 4 will drive the drive motor 5 and sampling cylinder 6 to move down, at the same time the output shaft of the drive motor 5 will drive the sampling cylinder 6 to rotate, so that it drills down into the soil, because the soil has viscosity, the right cavity of the baffle 9 in the sampling cylinder 6 will bring the soil into it back to the ground. When the need for stratified sampling to detect soil properties, can be through the controller 101 start servo motor 8, the output shaft of the servo motor 8 will drive all the bumps 13 and connecting piece 14 together clockwise rotation a certain angle, the bump 13 will be taken out to the left side when the sampling box 12, connecting rod 15 is moved together with the sampling box 12 a certain distance, the baffle 10 is pushed out by the sampling box 12, different depth of sampling box 12 in the soil will collect different soil layer soil sample, because the sampling box 12 opening is oblique cut type, reduces the resistance to move into the soil, the soil contact sampling box 12 will slide from the side to the sampling groove in the sampling box 12. After sampling, through the controller 101 control servo motor 8 output shaft reverse reset, at the same time drive connecting piece 14 reset, in turn drive connecting rod 15 pull sampling box 12 reset, baffle 10 is no longer extruded by the sampling box 12, baffle 10 will be automatically folded with the sampling cylinder 6 under the action of the magnet. Thus the sampling operation of the soil is completed, and through the stratified sampling function, it can facilitate the subsequent more accurate measurement of the properties of the soil.

[0029] According to Figure 1 and Figure 6 It also includes fixed frame 16, clamping ring 17 and spring 18, the base 2 is symmetrically fixed with fixed frame 16, two fixed frame 16 is respectively connected with clamping ring 17, each fixed frame 16 is connected with spring 18 between clamping ring 17.

[0030] According to different sampling requirements sometimes need to replace different size of sampling cylinder 6, in order to ensure that the sampling cylinder 6 will not move violently in the process of drilling, when the sampling cylinder 6 outer wall contact clamping ring 17, the sampling cylinder 6 will exert outward pressure on the clamping ring 17, so that it slides to both sides, so that the clamping ring 17 extrudes the spring 18 to both sides, so that the spring 18 is extruded, because the spring 18 has elastic restoring force, will produce inward force on the clamping ring 17, so as to carry on the basic limit, this clamping mode can adapt to different size of sampling cylinder 6, and then realize the basic clamping function.

[0031] According to Figure 1 and Figure 6 It also includes handle, the base 2 front side is fixed with handle, and the handle is provided with anti-skid sleeve.

[0032] According to Figure 1 and Figure 7 As shown in the drawings, further comprising universal wheel 20 and clamping piece 21, two universal wheels 20 are symmetrically bolted on the upper and lower sides of the rear side of the support 1, and each universal wheel 20 is rotatably connected with a clamping piece 21.

[0033] When it is needed to move the device to a specific position, first, the device is turned down, then the clamping piece 21 is opened, the restriction of the clamping piece 21 on the movement of the universal wheel 20 is released, so that the universal wheel 20 can rotate freely. Then, the handle on the device is dragged to drive the device to move. This operation is relatively simple, and the device can be easily moved, so that the flexibility of the device becomes higher.

[0034] According to Figure 1 and Figure 6 As shown in the drawings, further comprising brush holder 19, the brush holder 19 is bolted in the middle of the support 1, and a plurality of rigid bristles are distributed in the brush holder 19.

[0035] When the sampling cylinder 6 is taken out of the soil, a large amount of soil is usually adhered to the surface thereof. In order to facilitate the viewing of the sampling results, the brush holder 19 is arranged, and when the sampling cylinder 6 is rotated upward to be taken out by the electric sliding block 4 and the driving motor 5, the bristles on the brush holder 19 can basically clean the outer wall of the sampling cylinder 6. The brush holder 19 is designed as a detachable or adjustable structure, so that the maintenance and cleaning are facilitated.

[0036] After the sampling operation is completed, the sampling cylinder 6 needs to be detached from the output shaft of the driving motor 5, the sampling cylinder 6 is no longer clamped by rotating the sleeve 7, and is divided into left and right two parts, so that the soil which has been sampled can be conveniently taken out. When the device is not needed to be used, the electric sliding block 4 is controlled to reset by the controller 101, and then the output shafts of the driving motor 5 and the servo motor 8 are controlled to stop rotating, so that the whole device stops working and enters the standby state, which guarantees the integrity and continuity of the use of the device.

[0037] The above only describes the embodiments of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation according to the content of the present application, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
