DETAILED DESCRIPTION

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] The present embodiment provides a stratified sampling device for geological survey, which is used for sampling soil for geological survey. By setting up a sampling component 5, when multi-layer sampling of the soil is required, the sampling tube 501 only needs to be driven into the soil once to achieve multi-layer sampling of the soil, thereby effectively improving the sampling efficiency of the soil.

[0025] See also Figure 1 to Figure 5 A stratified sampling device for geological survey includes a frame 1, on which a through groove is opened, and the through groove is used to prevent the sampling component 5 from interfering with the frame 1 when moving up and down. A universal wheel 2 is installed on the bottom surface of the frame 1. By setting the universal wheel 2, the device can be easily moved. The internal thread of the frame 1 is connected to a ground rod 3, and the bottom end of the ground rod 3 is inserted into the ground. The top end of the ground rod 3 is fixedly connected to a knob. When the knob is turned clockwise, the ground rod 3 can be rotated and moved downward, so that the ground rod 3 can be inserted into the ground to fix the device.

[0026] A driving assembly 4 is provided on the frame 1, and the driving assembly 4 includes a threaded rod 401 rotatably connected to the inside of the frame 1, and a first motor 402 is installed on the upper surface of the frame 1, and the output end of the first motor 402 is fixedly connected to the top of the threaded rod 401, and the outer surface of the threaded rod 401 is threadedly connected to a threaded plate 403, and the back of the threaded plate 403 is slidably connected to the inner wall of the frame 1, and the front of the threaded plate 403 is fixedly connected to a support plate 404, and a sliding groove adapted to the threaded plate 403 is opened inside the frame 1. Start the first motor 402. When the first motor 402 drives the threaded rod 401 to rotate counterclockwise, the threaded plate 403 can be driven to move downward. When the first motor 402 drives the threaded rod 401 to rotate clockwise, the threaded plate 403 can be driven to move upward.

[0027] A right-angle plate 405 is fixedly connected to the upper surface of the support plate 404, and a second motor 406 is installed on the right-angle plate 405. The outer surface of the output end of the second motor 406 is fixedly connected to the first gear 407, and the outer surface of the sampling tube 501 is fixedly connected to the second gear 408. The first gear 407 is meshed with the second gear 408. The output end of the second motor 406 is rotatably connected to the inside of the support plate 404. When the second motor 406 is started, the second motor 406 can drive the first gear 407 to rotate, and the rotation of the first gear 407 can drive the second gear 408 to rotate.

[0028] The sampling assembly 5 includes a sampling tube 501, a tube cover 502 is sleeved on the top of the sampling tube 501, a group of second soil inlet grooves 509 arranged at equal distances are opened on the sampling tube 501, and there is damping between the sampling tube 501 and the tube cover 502. If no external force acts on the tube cover 502, the tube cover 502 will not move by itself.

[0029] Three inner cylinders 503 are arranged at equal distances inside the sampling cylinder 501, and the lower inner cylinder 503 is in contact with the inner bottom wall of the sampling cylinder 501. Every two inner cylinders 503 are connected by a first arc plate 504, and the outer surface of the inner cylinder 503 is in contact with the inner wall of the sampling cylinder 501. When the lower inner cylinder 503 is in contact with the inner bottom wall of the sampling cylinder 501, the three inner cylinders 503 will respectively block the three second soil inlet grooves 509 to prevent soil from seeping into the interior of the sampling cylinder 501.

[0030] The three inner cylinders 503 are all provided with first soil inlet grooves 505, and the three first soil inlet grooves 505 are respectively located directly below the three second soil inlet grooves 509. The upper surface of the upper inner cylinder 503 is fixedly connected with two symmetrical second curved plates 506, and the ends of the two second curved plates 506 away from the inner cylinder 503 are fixedly connected to the inner top wall of the cylinder cover 502. After the sampling assembly 5 is extended into the ground, the cylinder cover 502 is pulled upward, and the cylinder cover 502 can drive the second curved plates 506 and the inner cylinder 503 to slide upward, thereby The first soil inlet groove 505 and the second soil inlet groove 509 will gradually align, and the external soil will penetrate into the interior of the soil storage cylinder 508 through the first soil inlet groove 505 and the second soil inlet groove 509. Since the three inner cylinders 503 are evenly distributed from top to bottom inside the sampling cylinder 501, soils of different depths can be obtained at the same time, thereby realizing stratified sampling of the soil. Then, the cylinder cover 502 is pressed downward to the maximum distance, and the inner cylinder 503 will block the second soil inlet groove 509 to prevent the soil from continuing to penetrate.

[0031] The two second arc-shaped plates 506 are fixedly connected with positioning bars 507 on the sides away from each other. Two positioning grooves are provided inside the sampling tube 501. The two positioning bars 507 are respectively slidably connected inside the two positioning grooves. Through the cooperation between the positioning bars 507 and the positioning grooves, the inner tube 503 can be prevented from rotating inside the sampling tube 501 after the inner tube 503 is installed.

[0032] Working principle: When the utility model is in use, first move the device to the specified position, then turn the knob clockwise to make the piercing rod 3 rotate and move downward, and the piercing rod 3 can be driven into the ground to fix the device, and then start the first motor 402 and the second motor 406, so that the first motor 402 drives the threaded rod 401 to rotate counterclockwise, and the counterclockwise rotation of the threaded rod 401 can drive the threaded plate 403, the support plate 404 and the sampling component 5 to move downward, and the second motor 406 can drive the first gear 407 to rotate, and the rotation of the first gear 407 can drive the second gear 408 and the sampling component 5 to rotate, so that the sampling component 5 can rotate and move downward, so that the sampling component 5 can be extended into the ground, and then the first motor 402 and the second motor 406 are closed and the cylinder cover 502 is pulled upward, and the cylinder cover 502 can drive the second arc plate 506 and the inner cylinder 503 to slide upward, so that the first soil inlet trough 505 and the second soil inlet The soil grooves 509 will gradually align, and at this time, the external soil will penetrate into the interior of the soil storage cylinder 508 through the first soil inlet groove 505 and the second soil inlet groove 509. Since the three inner cylinders 503 are equidistantly distributed from top to bottom in the sampling cylinder 501, soil of different depths can be obtained at the same time, thereby realizing stratified sampling of the soil, and then the cylinder cover 502 is pressed downward to the maximum distance. At this time, the inner cylinder 503 will block the second soil inlet groove 509 to prevent the soil from continuing to penetrate, and then the first motor 402 is started again, so that the first motor 402 drives the threaded rod 401 to rotate clockwise, and the clockwise rotation of the threaded rod 401 can drive the threaded plate 403, the support plate 404 and the sampling assembly 5 to move upward. When the sampling cylinder 501 moves upward to the maximum distance, the three inner cylinders 503 are pulled out from the interior of the sampling cylinder 501, and then the soil storage cylinders 508 inside the three inner cylinders 503 are taken out in turn to obtain the required soil samples.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
