Description

Technical Field

[0001] The utility model relates to the technical field of samplers, and particularly to a soil layer slag sample sampler. Background Art

[0002] During the pile foundation drilling process, various different soil layers will be encountered during the drilling process, and the properties of each soil layer are different. By taking slag samples for analysis, the physical properties and chemical components of the soil layer can be determined, such as soil layer type, density, moisture content, clay content, etc., so as to evaluate its drillability and bearing capacity, thereby ensuring the quality and stability of the cast-in-place pile.

[0003] For the traditional soil layer sampler, the opening design at the bottom of the sampling cylinder is relatively simple. When sampling loose soil layers, during the extraction process, due to the loose structure between soil particles and the small friction coefficient between them and the inner wall of the sampling cylinder, the soil easily falls from the opening at the bottom of the sampling cylinder, resulting in a significant reduction in sampling efficiency and increasing the difficulty of sampling work.

Detailed implementation manners

[0025] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the scope of protection of the present utility model.

[0026] Accordingly, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts fall within the scope of protection of the present invention.

[0027] As Figure 1 shown, the present invention provides a soil layer slag sample sampler, which includes a holding part 10, a telescopic rod 20 and a sampling clip 30. The telescopic rod 20 is arranged between the holding part 10 and the sampling clip 30. A button 12 for controlling the operation of the sampling clip 30 is provided on the holding part 10, which makes the operation more convenient. The telescopic rod 20 is beneficial to the storage and transportation use of the sampler. The sampling clip 30 adopts a grasping sampling method, which can effectively avoid the problem that soil drops from the bottom of the sampling cylinder when the transmission sampling device samples in loose soil layers.

[0028] As Figure 2 shown, the holding part 10 includes a handle housing 11. A button 12 is arranged on the outer surface of the handle housing 11. A power supply component 14 and a microcontroller 13 are arranged inside the handle housing 11. The power supply component 14 is electrically connected to the microcontroller 13, and the button 12 is electrically connected to the microcontroller 13.

[0029] As Figure 3 shown, the telescopic rod 20 includes an outer rod 21. A first connection part 2102 is arranged at one end of the outer rod 21. The first connection part 2102 is detachably connected to one end of the handle housing 11 close to the button 12. An inner rod 22 is slidably arranged inside the outer rod 21. A second connection part 2203 is arranged at one end of the inner rod 22 far from the handle housing 11.

[0030] In this embodiment, a recovery positioning sleeve 2202 is arranged at one end of the outer surface of the inner rod 22 close to the second connection part 2203. An inner concave part 22021 is opened at one end of the recovery positioning sleeve 2202 far from the second connection part 2203. The gap between the inner concave part 22021 and the inner rod 22 is smaller than the thickness of the outer rod 21. When the telescopic rod 20 is fully retracted, the end of the outer rod 21 can be embedded into the inner concave part 22021. At the same time, in order to avoid the smooth embedding of the outer rod 21 into the inner concave part 22021, a chamfer is also arranged at the entrance of the inner concave part 22021 to prevent the outer rod 21 from being stuck outside the inner concave part 22021. When it needs to be extended, it can be pulled out with a little force, which can avoid being easily extended by external force in its contracted state.

[0031] In this embodiment, a plurality of positioning holes 2101 are linearly arranged on one end of the surface of the outer rod 21 away from the first connecting portion 2102, and a spring shaft 2201 is arranged on one end of the surface of the inner rod 22 away from the recovery positioning sleeve 2202. When the inner rod 22 slides inside the outer rod 21, the spring shaft 2201 can be snapped into any positioning hole 2101. The position of the spring shaft 2201 in the positioning hole 2101 can be adjusted according to the depth of the drilling, thereby adjusting the length of the sampler to provide a better experience when sampling.

[0032] like Figure 4 - 5 As shown, the sampling clamp 30 includes a first fixing member 31, which is arranged at the end of the second connecting portion 2203. The second fixing member 32 has an installation groove 3101 inside, and a motor 35 is fixedly arranged in the installation groove 3101. The motor 35 is electrically connected to the power supply assembly 14, and the motor 35 is communicatively connected to the microcontroller 13. Three first hinged portions 3102 are arranged on the end of the first fixing member 31 away from the second connecting portion 2203.

[0033] Furthermore, the sampling clamp 30 includes a second fixing member 32 , a threaded hole 3201 is provided at the center of the second fixing member 32 , and three second hinged portions 3202 are equally divided on the surface of the second fixing member 32 .

[0034] Furthermore, the sampling clamp 30 includes three claw structures 33 , each having a third hinged portion 3301 and a fourth hinged portion 3302 , the third hinged portion 3301 being hinged to the second hinged portion 3202 , and a connecting rod 34 being connected between the fourth hinged portion 3302 and the first hinged portion 3102 .

[0035] Furthermore, a fixing bracket 36 is disposed at the end of the output shaft of the motor 35 , and a driving bolt 37 is connected to one end of the fixing bracket 36 , and the driving bolt 37 is threadedly connected to the threaded hole 3201 .

[0036] It should be noted that the claw structure 33 includes an arcuate body 3303. When the three claw structures 33 are folded together, the arcuate body 3303 forms a spherical surface, which can completely wrap the soil to prevent it from falling after sampling.

[0037] Specifically, the working principle of this soil layer slag sample sampler is as follows: When in use, extend the telescopic rod 20 so that the spring shaft 2201 is stuck at the appropriate positioning hole 2101. Send an opening instruction for the sampling clamp 30 to the microcontroller 13 through the button 12, and then control the operation of the motor 35 to make the transmission bolt 37 rotate, and further make the second fixing member 32 move towards the first fixing member 31. At this time, the three claw structures 33 rotate and unfold outwards along the third hinge portion 3301. Then, control the sampler to align with the target soil, and send a closing instruction through the button 12 again, that is, control the motor 35 to reverse to make the three claws close, so as to wrap the soil inside the arc-shaped body 3303. Through the above structure, the problem in the prior art that due to the relatively simple design of the bottom opening of the sampling cylinder, after sampling the loose soil layer, the soil easily falls from the opening at the bottom of the sampling cylinder, resulting in a significant reduction in the sampling efficiency and increasing the difficulty of the sampling work is solved.

[0038] It should be noted that the specific model specifications of the microcontroller 13 and the motor 35 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0039] The power supply and its principle of the microcontroller 13 and the motor 35 are clear to those skilled in the art and will not be described in detail here.

[0040] The above further describes the present invention with the aid of specific embodiments. However, it should be understood that this specific description should not be construed as a limitation on the essence and scope of the present invention. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present invention.
