DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a soil sampling device for geological exploration includes an outer frame 1, an electric cylinder 2 is fixedly connected to the lower surface of the horizontal part of the outer frame 1, an arc groove mechanism 3 is fixedly connected to the output end of the electric cylinder 2, the bottom end of the arc groove mechanism 3 is slidably connected to a rotating mechanism 4, the bottom end of the rotating mechanism 4 is fixedly connected to a fixed round roller 5, the bottom of the fixed round roller 5 is threadedly connected to a sampling tube 6, the bottom of the sampling tube 6 is fixedly connected to a truncated cone-shaped soil-breaking block 61, a module 11 is fixedly connected to the middle of the inner wall of the left vertical part of the outer frame 1, and a pushing device 7 is slidably connected to the right side of the module 11.

[0025] In the above-mentioned scheme, the module 11 is composed of a vertical slide, a triangular slide and a horizontal block, wherein the upper surface of the horizontal block is fixedly connected to the spring 73, the left side of the slider 71 is slidably connected to the right side of the vertical slide of the module 11, and the slider 71 can slide on the surface of the vertical slide and the triangular slide of the module 11.

[0026] For details, see Figure 3 In the module 11 shown in this solution, the connection between the vertical slide and the triangular slide is shown as a right angle, but in actual implementation, the connection is set with an arc.

[0027] For details, see Figure 4 and Figure 5 A threaded groove is provided at the bottom of the fixed round roller 5, and a threaded device is provided on the outer surface of the upper end of the sampling tube 6, so that the sampling tube 6 can be threadedly connected with the fixed round roller 5 and the sampling tube 6 will not fall and affect the sampling whether it is lowered or raised during the implementation process. At the same time, after the sampling is completed, it is convenient for the user to remove the soil sample in time.

[0028] Furthermore, the truncated cone-shaped soil-breaking block 61 breaks the soil around the sampling tube 6 during the descent of the entire device, facilitating subsequent sampling operations.

[0029] Furthermore, when the electric cylinder 2 is excited, the output end moves downward, pushing the arc groove mechanism 3, the rotating mechanism 4, the fixed round roller 5, the sampling tube 6, the truncated cone-shaped soil-breaking block 61 and the pushing device 7 downward as a whole for sampling.

[0030] For details, see Figure 1 During the implementation of this solution, the user steps on the horizontal bars at the bottom ends of both sides of the vertical part of the outer frame 1 to ensure the stability and accurate sampling of this solution during implementation.

[0031] For details, see Figure 2 and Figure 3 The arc groove mechanism 3 includes an arc top plate 33, arc grooves 32 are fixedly installed on both sides of the lower surface of the arc top plate 33, and the two arc grooves 32 are slidably connected to the sliding rod 31 on one side close to each other. The rotating mechanism 4 includes a triangular ring 41, the middle part of the outer surface of the sliding rod 31 is rotatably connected to the inner wall of the triangular ring 41, and the bottom of the triangular ring 41 is fixedly connected to a rectangular frame 43. The vertical part of the rectangular frame 43 is fixedly connected to the middle part of one side close to each other. The bottom of the rectangular frame 43 is fixedly connected to the top of the fixed roller 5.

[0032] Specifically, during the implementation of this solution, when the arc-shaped top plate 33 moves downward, it can push the arc groove 32 and the slide bar 31 vertically downward, and at the same time, the triangular ring 41 sleeved on the outer surface of the slide bar 31 is also driven downward, that is, the rectangular frame 43 and the limiting roller 42 move downward at the same time.

[0033] For further information, see Figure 3 The pushing device 7 includes a spring 73, the bottom end of the spring 73 is fixedly connected to the upper end of the module 11, the top end of the spring 73 is fixedly connected to a push rod 72, the limiting roller 42 passes through the right side of the push rod 72 and is rotatably connected to the inner surface of the push rod 72. The left end of the push rod 72 is rotatably connected to a slider 71, and the left side of the slider 71 is slidably connected to the right side of the module 11.

[0034] In the above-mentioned embodiment, the slider 71 and the push rod 72 are at a 90° positional relationship during the initial descent process. When the slider 71 descends and slides to the triangular slide surface of the module 11, the angle between the slider 71 and the push rod 72 is no longer equal to 90°.

[0035] When the arc slot mechanism 3 and the rotating mechanism 4 descend, the push rod 72 is pushed to move downward, so that the slider 71 slides along the surface of the module 11 and the spring 73 is compressed downward.

[0036] For further information, see Figure 3 and Figure 4When the slider 71 slides downward to the surface of the triangular slide of the module 11, the sampling tube 6 has been lowered, and the slider 71 pushes the push rod 72 to move to the right. Since the right side of the push rod 72 is connected to the limit roller 42, when the push rod 72 is pushed to the right, the limit roller 42 moves to the right at the same time, which will drive the rectangular frame 43 and the triangular ring 41 to the right.

[0037] Specifically, when the triangular ring 41 moves to the right, it pushes the slide bar 31 that is rotatably connected to the inner wall of the triangular ring 41, and the slide bar 31 slides to the right along the arc groove 32. When the rectangular frame 43 moves to the right, it drives the fixed roller 5, the sampling tube 6, and the frustum-shaped soil breaking block 61 to rotate to the right, and the soil sample to be taken inside the sampling tube 6 is broken from the bottom soil.

[0038] Furthermore, the electric cylinder 2 operates and the output end moves upward. At this time, the compressed spring 73 wants to return to its original state and pushes the push rod 72 upward. At the same time, due to the operation of the electric cylinder 2, the entire structure moves upward.

[0039] Specifically, the spring 73 returns to its original state, and the slider 71 slides up along the triangular slider of the module 11 to the vertical slider, driving the push rod 72 to move to the left, so that the push rod 72 and the rotating mechanism 4 as a whole move to the original position during the upward movement, allowing the sampling tube 6 to smoothly complete the upward sampling.

[0040] It should be noted that the specific installation method of the electric cylinder 2, the circuit connection method and the control method used in the present invention are all conventional designs, and the present invention will not elaborate on them in detail.

[0041] The working principle of the utility model is as follows: after the user determines the sampling point, the user needs to step on the horizontal bars at the bottom ends of both sides of the vertical part of the outer frame 1 with his feet to ensure that the scheme remains stable during implementation. At this time, the user excites the electric cylinder 2, and the output end of the electric cylinder 2 moves downward, pushing the arc-shaped top plate 33 to move the slide bar 31 downward. When the slide bar 31 moves downward, it drives the triangular ring 41 downward, thereby pushing the rectangular frame 43 down, driving the fixed circular roller 5, the sampling tube 6 and the truncated cone-shaped soil-breaking block 61 downward for soil sampling. At this time, the truncated cone-shaped soil-breaking block 61 will break the soil around the sampling tube 6, and at the same time, the limiting roller 42 is pushed downward by the rectangular frame 43, thereby driving the push rod 72 to move downward, squeezing the spring 73, and at the same time, the slider 71 slides downward along the right side of the vertical slide of the module 11.

[0042] When the sampling tube 6 is completely lowered, the slider 71 slides down to the triangular slide surface of the module 11. Due to the structural characteristics of the triangular slide, the slider 71 rotates, so that the angle between the slider 71 and the push rod 72 is no longer maintained at 90°. At the same time, the slider 71 pushes the push rod 72 to the right, so that the limiting roller 42 moves to the right. Since the limiting roller 42 is fixedly connected to the rectangular frame 43 and the triangular ring 41, when the limiting roller 42 moves to the right, the rectangular frame 43 and the triangular ring 41 move to the right. At this time, the triangular ring 41 drives the slide bar 31 to slide in the inner cavity of the arc groove 32. At the same time, the rectangular frame 43 drives the fixed circular roller 5, the sampling tube 6 and the truncated cone-shaped soil-breaking block 61 to move to the right. However, since the sampling tube 6 goes deep into the underground for sampling, the fixed circular roller 5, the sampling tube 6 and the truncated cone-shaped soil-breaking block 61 will only rotate, so that the soil to be sampled inside the sampling tube 6 is broken from the underground soil, which is convenient for extracting samples.

[0043] Subsequently, the electric cylinder 2 continues to run, and its output end moves upward, thereby driving the arc-shaped top plate 33 upward, so that the slide rod 31 and the triangular ring 41 move upward. At this time, the triangular ring 41 will drive the limiting roller 42, the rectangular frame 43, the fixed circular roller 5, the sampling tube 6 and the truncated cone-shaped soil-breaking block 61 to move upward as a whole.

[0044] When the limiting roller 42 moves upward, it pushes the push rod 72 upward, and the spring 73 is no longer compressed, and returns to its original state to push the push rod 72 upward, thereby driving the slider 71 to slide upward along the triangular slide portion of the module 11 to the vertical slide portion.

[0045] When the slider 71 slides up to the vertical slider part, the slider 71 rotates and restores the position relationship of 90° with the push rod 72. At this time, the slider 71 pulls the push rod 72 to the left, so that the push rod 72 drives the limiting roller 42 and the rectangular frame 43, the triangular ring 41 and the slide bar 31 to move to the left. Therefore, the slide bar 31 slides along the arc groove 32 to the original position. At this time, the rectangular frame 43, the fixed circular roller 5, the sampling tube 6 and the truncated cone-shaped soil-breaking block 61 are lifted as a whole while maintaining a vertical state. When the whole is lifted above the ground, the user takes out the sampling tube 6 and the soil sample, and can clean the sampling tube 6 and continue the above sampling operation.

[0046] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
