Description

Technical Field

[0001] The utility model relates to the technical field of soft soil detection, in particular to a soft soil sampling mechanism and a soft soil detection device. Background Technique

[0002] Soft soil is mainly composed of silt sediments with large natural water content, high compressibility and low bearing capacity, and a small amount of humus; soft soil geological exploration is an important work in soft foundation reinforcement projects and dredging and reclamation soil improvement projects. Before the project is carried out, it is often necessary to first sample and analyze the performance of soft soil geology to ensure the construction quality.

[0003] When the traditional sampling device is directly inserted into soft soil, the fluidity of the soft soil will cause the soft soil to easily fall off and flow out when the sampling tube is pulled out, restricting the difficulty of taking soil for retaining samples when lifting. When facing solidified soft soil, it is necessary to collect solidified soft soil and deep soft soil for sampling and analysis. At this time, the solidification of the soft soil surface will increase its hardness, making it difficult for the traditional sampling device to directly penetrate from the surface of the solidified soft soil to the bottom for soft soil sampling, and it is also impossible to effectively collect soft soil samples at different depths, and it is also impossible to directly detect the performance data of soft soil at the construction site.

[0004] Therefore, it is particularly crucial to provide a sampling device that can effectively collect solidified soft soil, collect soft soil at different depths, and directly detect the performance data of soft soil at the construction site. Content of the Utility Model

[0005] In view of the problem that the sampling device in the above or the prior art is difficult to directly penetrate from the surface of the solidified soft soil to the bottom for soft soil sampling, the present utility model is proposed.

[0006] Therefore, the purpose of the present utility model is to provide a soft soil sampling mechanism.

[0013] Wherein, the soil inlet communicates with the movable cavity, and the soil box is provided with a notch, and the size is the same as that of the soil inlet.

[0014] As a preferred embodiment of the soft soil sampling mechanism of the present utility model, wherein: one end of the connecting rod is fixedly connected with a baffle, and when the soil box moves, it will drive the baffle to move through the connecting rod.

[0033] In order to make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be made in conjunction with the accompanying drawings of the specification.

[0034] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0035] Secondly, the so - called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that mutually excludes other embodiments.

[0036] Embodiment 1

[0037] Referring to Figures 1 to 6 , this is the first embodiment of the present utility model, and this embodiment provides a soft soil sampling mechanism.

[0038] Specifically, the soft soil sampling unit 100 adjusts the lifting control component 102 to make the drill machine component 101 reach various depths where sampling is required, and takes out the soft soil through the conveying part 101a - 2 to the soft soil conveying box 103, including the drill machine component 101, the lifting control component 102 arranged on one side of the drill machine component 101, and the soft soil conveying box 103 fixedly connected and installed on the drill machine component 101;

[0039] The drill machine component 101 includes a drill bit 101a, a lifting column 101b arranged outside the drill bit 101a, a sample - retaining part 101c arranged inside the lifting column 101b, a connecting rod 101d fixedly installed on the outer surface of the sample - retaining part 101c, a fixed rod 101e fixedly connected to one end of the lifting column 101b, and a motor 101f fixedly connected to one end of the fixed rod 101e;

[0040] Among them, the drill bit 101a is snap - fitted at one end of the motor 101f, and the lifting column 101b is provided with a tooth groove 101b - 1 on its surface.

[0041] Furthermore, the drill bit 101a is provided with a conical drilling part 101a - 1 and a conveying part 101a - 2.

[0042] Preferably, the lifting control component 102 includes a guide post 102a movably connected to the outer surface of the lifting column 101b, a base 102b disposed outside the guide post 102a, a transmission rod 102c movably connected and installed inside the base 102b, a limiting ring 102d adaptively installed on the outer surface of the transmission rod 102c, a hand wheel 102e extending from one end of the transmission rod 102c, a handle 102f fixedly installed at one end of the hand wheel 102e, and a gear 102g at the other end of the transmission rod 102c;

[0043] Wherein, the surface of the guide post 102a is provided with a notch 102b-1, and the top is set as an inclined opening for guiding the soft soil to move towards the soft soil conveying box 103 to avoid accumulation.

[0044] During use, turning the handle 102f drives the gear 102g to rotate through the transmission rod 102c, driving the lifting column 101b with a tooth groove 101b-1 to move downward. At this time, under the drive of the motor 101f, the conical drilling part 101a-1 of the drill bit 101a will first break the solidified layer on the surface of the soft soil, and then convey the soft soil to the conveying part 101a-2 through the conical drilling part 101a-1. The soft soil is conveyed to the soft soil conveying box 103 through the cooperation between the inside of the lifting column 101b and the conveying part 101a-2, and the solidified soft soil is sampled and collected simply and quickly.

[0045] In summary, only by turning the handle 102f can the earth drilling machine component 101 be moved downward, the solidified soft soil be sampled, and the lower-layer soft soil be continuously conveyed to the soft soil conveying box 103.

[0046] Embodiment 2

[0047] Referring to Figures 2 to 4 , for the second embodiment of the present invention, different from the previous embodiment, this embodiment provides a sample retention component 101c and a connecting rod 101d

[0048] Specifically, the sample retention component 101c includes an earth inlet 101c-1 opened inside the lifting column 101b, a movable cavity 101c-2 opened inside the lifting column 101b, an earth material box 101c-3 slidably connected and installed inside the movable cavity 101c-2, a spring 101c-4 disposed at the bottom of the earth material box 101c-3 and fixedly connected to the movable cavity 101c-2, a touch block 101c-5 movably connected inside the movable cavity 101c-2, and a return spring 101c-6 fixedly connected to the touch block 101c-5 and installed inside the movable cavity 101c-2;

[0049] Furthermore, the earth inlet 101c-1 communicates with the movable cavity 101c-2, and the earth material box 101c-3 is provided with a notch, and the size is the same as that of the earth inlet 101c-1.

[0050] Preferably, a baffle 101d-1 is fixedly connected to one end of the connecting rod 101d. When the soil box 101c-3 moves, the baffle 101d-1 will be driven to move by the connecting rod 101d.

[0051] It should be noted that three completely identical sets of the sample retaining component 101c are provided inside the lifting column 101b.

[0052] During use, when the conveying part 101a-2 rotates, it will convey the soft soil upward. At this time, the soft soil will enter the inside of the soil box 101c-3 from the soil inlet 101c-1. At this time, when the conveying part 101a-2 continues to rotate, it will touch the trigger block 101c-5, causing the trigger block 101c-5 to move back and forth under the elastic force of the return spring 101c-6. The trigger block 101c-5 pushes the soil box 101c-3, causing the soil box 101c-3 to move up and down frequently through the spring 101c-4 at the bottom, shaking the soft soil inside it and making it evenly placed. When the soft soil inside the soil box 101c-3 is collected to a certain weight, the soil box 101c-3 will not be rebounded by the spring 101c-4 under the drive of gravity. At this time, the soil inlet 101c-1 is closed, and the sampling of the soft soil is completed. Then, the connecting rod 101d connected to the soil box 101c-3 drives the baffle 101d-1 to move downward, opening the second sample retaining component 101c above. Repeat the above operation to collect the remaining two sample retaining components 101c. Because when the first sample retaining component 101c is collected, the soil inlets 101c-1 of the two sample retaining components 101c above are not opened, and the conveying part 101a-2 will continue to convey the soft soil upward, so the remaining two sample retaining components 101c will collect soft soil at different depths.

[0053] In summary, by separately providing three sample retaining components 101c to collect soft soil at different depths for sampling, it is convenient to detect and study the performance data of the soft soil.

[0054] Embodiment 3

[0055] Refer to Figure 6 , this is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a soft soil detection device.

[0056] Specifically, the soft soil detection device 200 includes a load-bearing plate 201 fixedly installed at the bottom of the lifting control assembly 102, a pulley 202 fixedly connected to the bottom of the load-bearing plate 201, a detector 203 fixedly installed on the surface of the load-bearing plate 201, and a handle 204 fixedly connected to the load-bearing plate 201.

[0057] Furthermore, the load-bearing plate 201 is provided with a through hole for movable cooperation with the lifting column 101b.

[0058] Preferably, a feed inlet 203a is provided on the surface of the detector 203. The feed inlet 203a is aligned with the soft soil conveying box 103, and the detector 203 is fixedly connected to the soft soil conveying box 103.

[0059] In summary, during use, the soft soil obtained by sampling is detected through the feed inlet 203a aligned with the conveying box 103, so that the performance data of the soft soil can be detected on the construction site. In addition, the soft soil at different depths collected by the three sample retaining components 101c can be detected individually, completing the on-site analysis of the soft soil and improving work efficiency.
