Description

Technical Field

[0001] The utility model relates to the field of geological survey, in particular to a geological survey sampler. Background Art

[0002] Geological survey is an investigation and research activity that uses various means and methods to explore and detect geology, determine the appropriate bearing layer, determine the foundation type based on the bearing capacity of the bearing layer, and calculate the foundation parameters.

[0003] Currently, there are various tools for geological surveys, each with different advantages. Among them, the plug-in type handheld geological survey sampler is lightweight and easy to carry with researchers, engineers and field workers. The plug-in design makes the sampling process simple. Users only need to insert the sampler into the target stratum to the required depth, and then use a lifting action to easily obtain samples of soil, rock or other geological materials, greatly improving work efficiency and flexibility.

[0004] However, the above-mentioned geological survey samplers still have certain problems. For example, after sampling is completed, the soil is often tightly attached to the inner wall of the sampler, which makes the separation process cumbersome and requires extra time and effort to peel off the soil samples one by one through meticulous manual operations. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a geological survey sampler to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a geological survey sampler, including a sampler, which consists of a connecting rod, a rotating handle, a sampling barrel and a sampling cone.

[0007] By adopting the above technical solution, the sampling cone and the sampling bucket are inserted into the soil to be sampled. After reaching the required depth, the rotating handle is turned to cover the first sampling groove with the sampling slide cover. Then, the geological survey sampler is lifted, the handle on the connecting rod is fixed, and the rotating handle is turned in the opposite direction. After the sampling slide cover is opened, the movable plate on the outer wall of the sampling bucket will push the soil sample, thereby separating the soil sample from the geological survey sampler.

[0008] Furthermore, the first sampling groove and the second sampling groove are both L-shaped, and the first sampling groove is communicated with the second sampling groove, and the first sampling groove runs through the sampling barrel.

[0009] By adopting the above technical solution, the soil sample can better enter the first sampling groove when the sampler is inserted into the soil.

[0010] Furthermore, the rotating shaft passes through the sampling barrel and the connecting rod, and the end of the rotating shaft passing through the sampling barrel is designed to be T-shaped, and the protruding part of the T-shape is in the shape of a round pancake.

[0011] By adopting the above technical solution, the sampling barrel and the connecting rod will not be affected when the rotating shaft rotates, and the rotating shaft has a limiting effect on the sampling barrel.

[0012] Furthermore, the sampling slide cover is designed as a quarter cylinder with a hollow center, and the outer walls at both ends of the sampling slide cover are designed to be inclined at 90°.

[0013] By adopting the above technical solution, the sampling sliding cover can be slid out more conveniently and the sampling sliding cover is easier to cut the soil.

[0014] Furthermore, a set of handles are fixedly mounted on the outer wall of the connecting rod.

[0015] By adopting the above technical solution, the handle can be fixed to fix the connecting rod and the sampling bucket, so that the connecting rod and the sampling bucket will not be affected when the rotating shaft rotates.

[0016] Furthermore, the movable plate is designed to be T-shaped, and the springs are fixedly connected to the protruding outer walls at both ends of the movable plate.

[0017] By adopting the above technical solution, the spring can absorb the thrust and help the movable plate to reset after the soil sample separation is completed.

[0018] Furthermore, the push plate is designed to be L-shaped, and the angle between the push plate and the opening of the sampling slide cover is 90°, and when the sampling slide cover is retracted into the sampling barrel, the end of the L-shaped horizontal plate of the push plate fits against the outer wall of the movable plate.

[0019] By adopting the above technical solution, when the rotating shaft rotates 90 degrees to retract the sampling slide cover, it will drive the push plate to rotate, so that the protruding part of the push plate pushes the movable plate to separate the soil sample.

[0020] In summary, the present invention has the following beneficial effects:

[0021] The utility model is provided with a rotating handle, a sampling bucket and a sampling cone. The sampling cone and the sampling bucket are inserted into the soil to be sampled. After reaching the required depth, the rotating handle is rotated, and the sampling slide cover is used to cover the first sampling groove. Then, the geological survey sampler is lifted, the handle on the connecting rod is fixed, and the rotating handle is rotated in the opposite direction. After the sampling slide cover is opened, the movable plate on the outer wall of the sampling barrel will push the soil sample, thereby separating the soil sample from the geological survey sampler.

The rotating shaft 7 passes through the sampling barrel 4 and the connecting rod 2, so that the rotating shaft 7 will not affect the sampling barrel 4 and the connecting rod 2 when it rotates, and the bottom end of the connecting rod 2 is fixedly connected to the top of the sampling barrel 4, and a first sampling groove 401 is provided on the outer wall of the sampling barrel 4. The first sampling groove 401 passes through the sampling barrel 4, so that when the sampler 1 is inserted to a specified depth, the required soil will fill the first sampling groove 401, and the outer wall of the sampling barrel 4 with the first sampling groove 401 is slidably installed with a movable plate 403, which can help separate the soil sample from the sampler 1, and the bottom end of the sampling barrel 4 is fixedly connected with the sampling cone 5, which facilitates the insertion of the sampler 1. The end of the movable plate 403 is fixedly installed with a spring 404, and the other end of the spring 404 is fixedly installed on the inner wall of the sampling barrel 4. The spring 404 can absorb the thrust and help the movable plate 403 to reset after the soil sample separation is completed. The outer wall of the sampling cone 5 is provided with a second sampling groove 501, and the second sampling groove 501 is communicated with the first sampling groove 401, so that the soil sample can better enter the first sampling groove 401. The outer wall of the rotating shaft 7 is fixedly installed with a sampling slide 6 and a push plate 701. The sampling slide 6 can cover the first sampling groove 401 and seal the soil sample in the first sampling groove 401. The push plate 701 can push the movable plate 403 when the sampling slide 6 is retracted to separate the soil sample. The sampling barrel 4 is provided with a rotating groove corresponding to the push plate 701, and the inner wall of the sampling barrel 4 is provided with a slide groove 402 corresponding to the sampling slide 6, which can facilitate the sampling slide 6 to slide out, thereby cutting the soil to obtain the soil sample.

[0035] See also Figure 1 、 Figure 3 and Figure 8 The first sampling groove 401 and the second sampling groove 501 are both L-shaped, and the first sampling groove 401 is connected to the second sampling groove 501, and the first sampling groove 401 passes through the sampling barrel 4, so that when the sampler 1 is inserted into the soil, the soil sample can better enter the first sampling groove 401.

[0036] See also Figure 5 、 Figure 6 and Figure 8The rotating shaft 7 passes through the sampling barrel 4 and the connecting rod 2, so that the rotating shaft 7 will not affect the sampling barrel 4 and the connecting rod 2 when rotating, and the end of the rotating shaft 7 passing through the sampling barrel 4 is designed to be T-shaped, and the protruding part of the T-shape is in the shape of a round cake, so that the rotating shaft 7 has a limiting effect on the sampling barrel 4.

[0037] See also Figure 3 - Figure 8 The sampling slide cover 6 is designed as a quarter-cylinder with a hollow middle part, which makes it easier for the sampling slide cover 6 to slide out, and the outer walls at both ends of the sampling slide cover 6 are designed with a 30° tilt, which makes it easier for the sampling slide cover 6 to cut the soil.

[0038] See also Figure 1 、 Figure 3 、 Figure 5 and Figure 6 A set of handles are fixedly installed on the outer wall of the connecting rod 2, which can fix the handles to fix the connecting rod 2 and the sampling barrel 4, so that the connecting rod 2 and the sampling barrel 4 will not be affected when the rotating shaft 7 rotates.

[0039] See also Figure 8 and Figure 9 The movable plate 403 is designed in a T shape, and the spring 404 is fixedly connected to the protruding outer walls of the movable plate 403, so that the spring 404 can absorb the thrust and help the movable plate 403 to reset after the soil sample separation is completed.

[0040] See also Figure 6 and Figure 8 The push plate 701 is designed in an L shape, and the angle between the push plate 701 and the opening of the sampling slide cover 6 is 90°. When the sampling slide cover 6 is retracted into the sampling barrel 4, the L-shaped horizontal plate end of the push plate 701 is in contact with the outer wall of the movable plate 403, so that when the rotating shaft 7 rotates 90° to retract the sampling slide cover 6, it will drive the push plate 701 to rotate, so that the protruding part of the push plate 701 pushes the movable plate 403 to separate the soil sample.

[0041] The working principle of the present invention is as follows: when it is necessary to use the geological survey sampler, first place the sampling cone 5 on the soil surface and press the rotating handle 3 downwards. Since the rotating handle 3 is fixedly connected to the rotating shaft 7, and the connecting rod 2 is fixedly connected to the sampling barrel 4, and the rotating shaft 7 is a T-shaped design for the end portion that passes through the sampling barrel 4, the sampling barrel 4 is rotatably mounted on the outer wall of the rotating shaft 7, and the sampling barrel 4 and the sampling cone 5 are fixedly connected. At this time, the sampler 1 as a whole will enter the soil. Since the outer walls of the sampling barrel 4 and the sampling cone 5 are respectively provided with a first sampling groove 401 and a second sampling groove 501, and the first sampling groove 401 passes through the sampling barrel 4, and the first sampling groove 401 is communicated with the second sampling groove 501, the soil will fill the sampling groove, rotate the rotating handle 3, and the rotating handle 3 drives the rotating shaft 7. The cover 6 is fixedly connected to the rotating shaft 7, and the sampling barrel 4 is provided with a slide groove 402 corresponding to the sampling slide cover 6. At this time, the sampling slide cover 6 will be rotated out of the slide groove 402. When the sampling slide cover 6 covers the first sampling slot 401, because the sampling slide cover 6 is designed to be hollow in the middle, the sampling slide cover 6 will seal the soil sample in the first sampling slot 401. Lift the sampler 1, fix the handle of the connecting rod 2, and rotate the rotating handle 3 90° in the opposite direction again. Because the angle between the push plate 701 and the opening of the sampling slide cover 6 is 90°, the horizontal plate of the push plate 701 will push the movable plate 403, so that the movable plate 403 pushes the soil sample, causing the soil sample to separate from the sampling barrel 4. At the same time, the spring 404 will absorb the thrust. After separation, the spring 404 rebounds to reset the movable plate 403.

The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
