Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a rock and soil sampling device for geotechnical engineering. Background Art

[0002] From the perspective of engineering construction, rock and soil is a general term for any kind of rock and soil that makes up the earth's crust. Rock and soil can be subdivided into five categories: hard rock, sub-hard soft rock, weakly connected, loosely unconnected, and with special composition, structure, state and properties. Geotechnical engineering is a new technical system established in civil engineering practice. Geotechnical engineering takes solving rock and soil engineering problems, including foundations, slopes and underground engineering, as its research object. The rock and soil sampling device is a tool for extracting the original soil of the lower test soil as a sample to understand the properties of its base layer. It is used to analyze soil samples of construction strata before various engineering construction.

[0003] However, when sampling, the existing sampling device still requires the operator to hold the driving device throughout the whole process, and the operator's control can prevent the sampling tube and the driving device from tipping over, so as to ensure that the sampling tube moves vertically downward for sampling during the sampling process, which increases the operator's workload. In addition, the weight of the driving device is generally large, and manual handling is required for multiple times during sampling, which further increases the operator's workload and reduces the operator's work efficiency. It is more troublesome to use and lacks practicality.

[0004] Therefore, it is necessary to invent a geotechnical engineering geotechnical sampling device to solve the above problems. Utility Model Content

[0023] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0024] like Figure 1-Figure 5 As shown, the geotechnical sampling device for geotechnical engineering disclosed in the present invention may include: a moving mechanism 1, a limiting mechanism 2, a sampling mechanism 3 and other components.

[0025] like Figure 2 As shown, in the present disclosure, the mobile mechanism 1 includes a base 11, a slot 12, a universal wheel 13 and a support rod 14, wherein the slot 12 is opened on the surface of the base 11 and passes through the base 11, the universal wheel 13 is rotatably connected to the bottom of the base 11, and the support rod 14 is slidably connected to the base 11 and passes through the base 11.

[0026] Therefore, before performing the sampling operation, the operator can quickly move the sampling device to the sampling location through the universal wheel 13, avoiding the operator's time-consuming and laborious transportation of the sampling device. During sampling, the stability of the sampling device is ensured by inserting the support rod 14 into the ground, avoiding shaking during the sampling process that affects the sampling effect and improving the sampling efficiency.

[0027] like Figure 2-3As shown, in a preferred embodiment, the limiting mechanism 2 includes a column 21, a sliding limiting groove 22, a mounting frame 23, a connecting rod 24, a limiting slider 25, a first magnetic block 26, a handle 27 and a second magnetic block 28, wherein the column 21 is fixedly connected to the top of the base 11, the sliding limiting groove 22 is opened on the surface of the column 21 and passes through the column 21, the mounting frame 23 is fixedly connected to the outer side of the top of the column 21, the connecting rod 24 is slidably connected to the mounting frame 23 and passes through the mounting frame 23, the limiting slider 25 is fixedly connected to the inner side end of the connecting rod 24, the limiting slider 25 is slidably matched with the sliding limiting groove 2, the first magnetic block (26) is provided with two pieces, which are respectively fixedly connected to the outer sides of the two mounting frames (23), the handle 27 is fixedly connected to the outer side end of the connecting rod 24 and is located on the outer side of the mounting frame 23, and the second magnetic block 28 is fixedly connected to the side of the handle 27 close to the mounting frame 23. It is noted that the limit slider 25 can be accommodated in the sliding limit slot 22 to allow the sliding rod 31 to slide up and down through the position where the limit slider 25 is located. After the limit slider 25 is pushed out of the sliding limit slot 22, as shown in the attached Figure 3 As shown, the limiting slider 25 can support the sliding rod 31, and the first magnetic block (26) and the second magnetic block (28) are attracted to each other.

[0028] Therefore, before performing the sampling operation, the operator first slides the sliding rod 31 to the top of the column 21, and then drives the connecting rod 24 to slide by pushing the handle 27. The sliding of the connecting rod 24 drives the limit slider 25 to slide and limit the sliding rod 31 to prevent the sliding rod 31 from falling down and freeing the operator's hands. The state of the limit slider 25 is stabilized by the adsorption effect of the first magnetic block 26 and the second magnetic block 28 to avoid the sliding rod 31 falling off. After the preparation work is completed, the operator pulls the handle 27 outward to drive the first magnetic block 26 and the second magnetic block 28 to separate, and at the same time drives the connecting rod 24 to slide. The sliding of the connecting rod 24 drives the limit slider 25 to slide and releases the limit on the sliding rod 31. At this time, the sampling operation can be performed.

[0029] like Figure 3-5As shown, in the present disclosure, the sampling mechanism 3 includes a sliding rod 31, a driving cylinder 32, a connecting seat 33, a slot 34, a first through hole 35, a screw 36, a nut 37, a sampling tube 38, a second through hole 39 and an air pump hose 310, wherein the sliding rod 31 is slidably connected between the two columns 21 through a sliding limit groove 22, the driving cylinder 32 is fixedly connected below the sliding rod 31, the connecting seat 33 is fixedly connected to the end of the piston rod of the driving cylinder 32, and the slot 34 is opened at the connecting seat. On the surface of the connecting seat 33, a first through hole 35 is opened on the surface of the connecting seat 33 and passes through the connecting seat 33, a second through hole 39 is opened on the surface of the sampling tube 38 and passes through the sampling tube 38, the sampling tube 38 and the connecting seat 33 are clamped by the clamping groove 34, the screw 36 passes through the first through hole 35 and the second through hole 39 and is slidingly connected to the connecting seat 33 and the sampling tube 38, the nut 37 is threadedly connected to the outside of the screw 36, one end of the air pump hose 310 is connected to the driving cylinder 32, and the other end is connected to the air pump.

[0030] Therefore, when the operator connects the sampling tube 38 and the driving cylinder 32, he first inserts the sampling tube 38 into the slot 34 and aligns the first through hole 35 with the second through hole 39, then passes the screw 36 through the first through hole 35 and the second through hole 39, and then rotates the nut 37 to make the nut 37 contact with the surface of the connecting seat 33 and limit the screw 36. At this time, the operator can connect and fix the air pump hose 310 to the driving cylinder 32.

[0031] The sliding rod 31 can slide along the sliding limit groove 22 to ensure that the sampling tube 38 can move vertically up and down, reducing labor intensity; when sampling, the operator cooperates with the driving cylinder 32 to push the sampling tube 38 downward to complete the sampling.
