[0003] Existing sampling devices are all linear and cannot adjust the angle of their sampling tubes. This means that the sampling tubes must be perpendicular to the sampling profile during sampling. If transverse sampling is required on the inner wall of the pit, the existing sampling devices are not convenient for workers to operate by hand because the sampling location is far from the bottom of the pit. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this patent is to provide a sampling device with an adjustable angle.

Detailed Implementation

[0019] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0020] See Figure 1 , Figure 2 , Figure 3 This is a schematic diagram of the structure of this patent. An angle-adjustable sampling device includes a first connecting rod 1 and a sampling cylinder 2. A mounting base 3 is installed at the end of the first connecting rod 1, and the sampling cylinder 2 is rotatably installed in the mounting base 3.

[0021] Because its sampling cylinder 2 is installed on the motor 34 in the rotating frame 33, the angle of the sampling cylinder 2 can be adjusted by rotating the rotating frame 33, so that the device can perform lateral sampling at some locations such as the inner wall of the foundation pit.

[0022] Mounting base 3 includes sleeve 31, placement groove 32, rotating frame 33 and motor 34. Sleeve 31 is sleeved on the outside of the first connecting rod 1. Placement groove 32 is provided on the lower wall of sleeve 31. Rotating frame 33 is rotatably installed in placement groove 32. Motor 34 is inserted and installed in rotating frame 33. Motor 34 is electrically connected to an external power source. Sampling cylinder 2 is installed at the output end of motor 34.

[0023] By starting the motor 34, the sampling cylinder 2 can be rotated, allowing it to be screwed into the inner wall of the external foundation pit to collect soil samples.

[0024] A first electrically controlled push rod 4 is inserted and installed on the inner side wall of the placement slot 32. The first electrically controlled push rod 4 is electrically connected to an external power source. A positioning block 5 is installed at the output end of the first electrically controlled push rod 4. The positioning block 5 can fit against the side wall of the rotating frame 33.

[0025] The positioning block 5 is pushed downward by the first electric push rod 4, so that it can be pressed onto the rotating frame 33, and then the angle of the rotating frame 33 can be fixed.

[0026] The rotating frame 33 includes a frame body 331, a second connecting rod 332, and a toothed groove 333. The second connecting rod 332 is inserted into the side wall of the frame body 331. The two ends of the second connecting rod 332 pass through the side wall of the frame body 331 and are rotatably mounted on the inner wall of the placement groove 32. The side wall of the second connecting rod 332 is provided with a toothed groove 333. The lower wall of the positioning block 5 is provided with a protruding tooth 6, which can be inserted into the toothed groove 333.

[0027] The toothed groove 333 on the second connecting rod 332 can engage with the protruding tooth 6 below the positioning block 5, so that when the positioning block 5 is pressed on the second connecting rod 332, the protruding tooth 6 is inserted into the toothed groove 333, ensuring that the second connecting rod 332 will not rotate again, thus fixing the angle of the frame 331.

[0028] The sampling cylinder 2 has a through groove 7 on its side wall, which penetrates the inner side wall of the sampling cylinder 2. An insert plate 8 is inserted into the through groove 7. A push ring 9 is installed at one end of the insert plate 8 located outside the through groove 7. A second electrically controlled push rod 10 is installed on the lower wall of the rotating frame 33. The second electrically controlled push rod 10 is electrically connected to an external power source.

[0029] The end of the insert plate 8 in this paper is flexible and can be bent. When the insert plate 8 is inserted into the through groove 7, the end of the insert plate 8 will pass through the other side of the through groove 7, thereby blocking the soil sample in the sampling tube 2, thus preventing the soil sample from sliding out of the sampling tube 2 when the device is removed from the soil.

[0030] By setting the second electrically controlled push rod 10, the insert plate 8 can be pushed by the push ring 9.

[0031] The output end of the second electric control push rod 10 is equipped with a rotating block 11, and the side wall of the push ring 9 is provided with an annular groove 12, and the rotating block 11 can be slidably installed in the annular groove 12.

[0032] By cooperating with the annular slide groove 12, the second electrically controlled push rod 10 can be prevented from interfering with the rotation of the sampling cylinder 2.

[0033] The outer side of the sampling cylinder 2 is provided with an external thread 13;

[0034] The external thread 13 allows the sampling cylinder 2 to be easily inserted into the external soil when it rotates.

[0035] When this patent is in operation, when sampling is performed by this device, the angle of the sampling tube 2 is first adjusted according to the tilt angle of the sampling position so that the sampling tube 2 can be perpendicular to the sampling plane. Then, by starting the motor 34, the sampling tube 2 is driven to rotate so that the sampling tube 2 can be screwed into the inner wall of the external foundation pit through the external thread 13 to collect samples of the soil inside.

[0036] After the collection is completed, the motor 34 stops, and then the second electric control push rod 10 can be pushed out to drive the push ring 9 to push the insert plate 8, so that the end of the insert plate 8 will pass through the other side of the through groove 7, thereby blocking the soil sample in the sampling tube 2, thus preventing the soil sample from sliding out of the sampling tube 2 when the device is removed from the soil.

[0037] It will be apparent to those skilled in the art that this patent is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this patent. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this patent is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this patent. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
