Description

Technical Field

[0001] This utility model belongs to the field of soil testing technology in geotechnical engineering, and particularly relates to a sampling device for soil testing in geotechnical engineering. Background Technology

[0002] In soil sampling devices for geotechnical engineering testing, the soil sampler is the core tool. It collects undisturbed soil samples by penetrating and pressing down, and is generally suitable for sampling shallow clay soils. The soil sampler removes the soil sample completely by static pressure, avoiding the influence of disturbance on the test results. It can preserve the natural structure, moisture content and stress state of the soil to the greatest extent, and plays an indispensable role in soil testing and collection.

[0003] The problem with existing technology is that when sampling with existing soil samplers, soil may adhere to the inside of the cylinder and be difficult to remove. It is also difficult to clean the soil adhering to the inner wall of the cylinder, which makes soil sampling and subsequent cleaning work time-consuming and labor-intensive, affecting work efficiency.

The linkage component 43 is located on the upper end of the pushing component 41.

[0023] The above solution is adopted: by setting up a cleaning and pushing device 4, the soil inside the cylinder 1 is pushed out, which facilitates the removal of the soil and can also clean the soil adhering to the inner wall of the cylinder 1.

[0024] refer to Figure 1 , Figure 2 and Figure 3 The pushing component 41 includes a screw 411, a motor 412, a limiting strip 413, and a push plate 414. The screw 411 is located inside the cylinder 1, and its upper end extends into the support rod 2 and is rotatably connected to the cylinder 1. The motor 412 is fixedly connected to the upper end of the screw 411 and is fixedly connected to the support rod 2. There are two limiting strips 413, which are fixedly connected to the left and right sides of the cylinder 1 respectively. The push plate 414 is located at the upper end of the cylinder 1 and is movably connected to the cylinder 1. The push plate 414 is sleeved on the surface of the screw 411 and is threadedly connected to the screw 411. The left and right ends of the push plate 414 are respectively sleeved on the surfaces of the two limiting strips 413 and are slidably connected to the limiting strips 413.

[0025] The above solution is adopted: by setting the pushing component 41, the soil inside the cylinder 1 is pushed downward into the cylinder 1, which facilitates the removal of the soil.

[0026] refer to Figure 1 , Figure 2 and Figure 4 The vibration assembly 42 includes a positioning rod 421, a striking element 422, a top plate 423, a push spring 424, and a pressure rod 425. The positioning rod 421 is located on the right side of the support rod 2, and its lower end is fixedly connected to the upper surface of the cylinder 1. The positioning rod 421 and the screw 411 are positioned corresponding to each other. The striking element 422 is sleeved on the lower surface of the positioning rod 421 and is slidably connected to the positioning rod 421. The striking element 422 is in contact with the upper surface of the cylinder 1. The top plate 423 is fixedly connected to the upper end of the positioning rod 421. The push spring 424 is sleeved on the upper end of the positioning rod 421, and its upper and lower ends are fixedly connected to the lower surface of the top plate 423 and the upper surface of the striking element 422, respectively. The pressure rod 425 is fixedly connected to the left side of the upper end of the striking element 422, and its left end extends into the interior of the support rod 2 and is movably connected to the support rod 2.

[0027] The above solution is adopted: by setting up the vibration component 42, the cylinder 1 is hammered downwards. By hammering the cylinder 1 downwards, the soil inside the cylinder 1 can be shaken out downwards. Combined with the pushing component 41, the efficiency of soil removal is improved.

[0028] refer to Figure 2 , Figure 3 and Figure 4 The linkage component 43 includes a turntable 431 and protrusions 432. The turntable 431 is sleeved on the upper surface of the screw 411 and is fixedly connected to the screw 411. There are two protrusions 432, which are fixedly connected to the left and right sides of the upper surface of the turntable 431 respectively. The positions of the two protrusions 432 and the two pressure rods 425 correspond to each other and are adapted to each other.

[0029] The above scheme is adopted: by setting up a linkage component 43, which is used to cooperate with the push component 41 to drive the vibration component 42, it has the function of simultaneously linking the two vibration components 42 to vibrate the cylinder 1.

[0030] refer to Figure 2 and Figure 3 A cone head 5 is provided at the lower end of the screw 411, and the cone head 5 is fixedly connected to the screw 411.

[0031] The above solution involves installing a cone 5 at the lower end of the screw 411, which can better break through the soil and facilitate insertion into the ground.

[0032] refer to Figure 2 and Figure 3 The outer side of the push plate 414 contacts the inner wall of the cylinder 1.

[0033] The above solution is adopted: by setting the outer side of the pusher plate 414 to contact the inner wall of the cylinder 1, the inner wall of the cylinder 1 can be scraped while pushing the soil, and the soil attached to the inner wall of the cylinder 1 can be scraped off.

[0034] The working principle of this utility model:

[0035] When removing the soil from inside the cylinder 1, the control motor 412 drives the screw 411 to rotate. Simultaneously, the rotation of the screw 411 causes the push plate 414 to move downwards on the surfaces of the two limit strips 413. As the push plate 414 moves downwards inside the cylinder 1, it pushes out the soil and scrapes the inner wall of the cylinder 1, thus pushing and cleaning the soil. At the same time, the rotation of the screw 411 causes the turntable 431 to rotate. The rotation of the turntable 431 causes the two protrusions 432 to rotate, eventually pressing against the pressure rod 425. The pressure rod 425 is squeezed, which drives the striking element 422 to move upward on the surface of the positioning rod 421. As the striking element 422 moves upward, it squeezes the push spring 424. After the protrusion 432 rotates to stop squeezing the pressure rod 425, the push spring 424 will quickly rebound. The striking element 422 will be subjected to its own weight and the downward thrust of the push spring 424 to hammer the cylinder 1 downward on the surface of the positioning rod 421. As the protrusion 432 repeatedly squeezes and releases the pressure rod 425, it drives the striking element 422 to reciprocate to hammer and vibrate the cylinder 1, thereby cooperating with the pushing component 41 to push and clean.

[0036] In summary, this soil sampling device for geotechnical engineering, through the coordinated use of a cylinder 1, support rod 2, handle 3, cleaning and pushing device 4, pushing component 41, screw 411, motor 412, limit bar 413, push plate 414, vibration component 42, positioning rod 421, striking component 422, top plate 423, push spring 424, pressure rod 425, linkage component 43, turntable 431, protrusion 432, and cone head 5, solves the problem of soil adhering to the inside of the cylinder during sampling, which is difficult to remove and clean the soil adhering to the inner wall of the cylinder. This results in time-consuming and labor-intensive soil sampling and subsequent cleaning work, affecting work efficiency.
