Description

Technical Field

[0001] This utility model relates to the field of soil and rock sampling, and in particular to a layered sampling device for soil and rock engineering. Background Technology

[0002] The structure and properties of soil and rock have a significant impact on bearing capacity, making soil and rock sampling and analysis an essential step before construction. The quality of soil samples is paramount during sampling. Soil structure is easily disturbed during drilling and sampling; using disturbed samples will inevitably lead to erroneous conclusions, potentially causing engineering accidents or wasting construction funds. Different sampling tools are suitable for different soil types. To obtain qualified soil samples, appropriate sampling tools and methods should be selected based on the required soil quality grade and soil type. Layered sampling of soil and rock facilitates the collection and analysis of soil and rock layers, providing a more comprehensive reflection of the sampled soil and rock structure and properties. However, existing layered soil and rock sampling devices suffer from structural instability, leading to tilting and shaking during operation. Utility Model Content

[0003] The purpose of this invention is to provide a layered sampling device for geotechnical engineering in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A geotechnical engineering layered sampling device includes a sampling mechanism for sampling, and a support mechanism for supporting the weight of the entire device. A fixing mechanism for fixing the entire device is installed on the support mechanism.

[0006] The support mechanism includes a base plate placed horizontally on the ground, a positioning component installed under the base plate, stiffening ribs on the base plate, and a top plate installed on the top of the stiffening ribs;

[0007] The fixing mechanism includes a screw fixing seat mounted on the base plate, a rotating screw mounted vertically on the screw fixing seat, a stabilizing plate mounted on the rotating screw, the stabilizing plate being threadedly connected to the rotating screw, a soil-breaking plate mounted vertically below the stabilizing plate, a locking component being installed inside the soil-breaking plate, a positioning rod sleeve mounted obliquely on the base plate, a reinforcing screw being installed inside the positioning rod sleeve, and a threaded connection between the positioning rod sleeve and the reinforcing screw.

[0008] Further configuration: The positioning component includes a pin sleeve installed under the base plate, a positioning pin rotatably installed inside the pin sleeve, and a gripper installed under the base plate. The gripper and the positioning pin are clamped together by an interference fit.

[0009] Further configuration: The locking assembly includes a lifting screw threadedly connected to the soil-breaking plate, a vertical groove is provided on the soil-breaking plate, and a locking slider is rotatably installed below the lifting screw, with the locking slider slidably connected to the groove.

[0011] Further configuration: The rotating screw is rotatably connected to the screw fixing seat and the base plate, and the soil-breaking plate is slidably connected to the base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By setting up support and fixing mechanisms, when the device is sampling, the stiffening plates on the bottom plate reinforce the sampling mechanism. The positioning pin at the bottom of the bottom plate rotates to be vertical to the ground and inserts into the ground to position and fix the device. The rotating screw on the bottom plate rotates to make the soil-breaking plate break the soil downward. The reinforcing screw installed at an angle on the bottom plate is inserted into the groove of the soil-breaking plate through the positioning rod. Then, the lifting screw at the top of the soil-breaking plate is rotated to make the locking slider move downward through the groove and lock and fix it with the reinforcing screw. The soil-breaking plate and the reinforcing screw are cross-fixed, thereby improving the stability of the device operation. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-4 As shown, a geotechnical engineering stratified sampling device includes a sampling mechanism 2 for sampling, and a support mechanism 10 for supporting the weight of the entire device. A fixing mechanism 9 for fixing the entire device is installed on the support mechanism 10.

[0025] In this embodiment: the support mechanism 10 includes a base plate 11 placed horizontally on the ground, a positioning component installed under the base plate 11, a stiffener 12 provided on the base plate 11, a top plate 13 installed at the top of the stiffener 12, the positioning component includes a pin sleeve 41 installed under the base plate 11, a positioning pin 42 rotatably installed inside the pin sleeve 41, and a gripper 43 installed under the base plate 11, the gripper 43 and the positioning pin 42 are clamped by an interference fit; during operation, the stiffener 12 on the base plate 11 provides strong support to the sampling mechanism 2 installed on the base plate 11, and when the positioning pin 42 under the base plate 11 rotates to be perpendicular to the ground, it inserts into the ground to position the device.

[0026] In this embodiment: the fixing mechanism 9 includes a screw fixing seat 31 mounted on the base plate 11, a rotating screw 32 vertically mounted on the screw fixing seat 31, a stabilizing plate 33 provided on the rotating screw 32, the stabilizing plate 33 being threadedly connected to the rotating screw 32, a soil-breaking plate 34 vertically mounted below the stabilizing plate 33, a locking component provided inside the soil-breaking plate 34, a positioning rod sleeve 36 obliquely mounted on the base plate 11, a reinforcing screw 37 installed inside the positioning rod sleeve 36, and a threaded connection between the positioning rod sleeve 36 and the reinforcing screw 37, the rotating screw 32 being rotatably connected to the screw fixing seat 31 and the base plate 11, the soil-breaking plate 34 being slidably connected to the base plate 11, and the locking component including a screw... A lifting screw 39 is connected to the soil-breaking plate 34. A vertical groove 35 is provided on the soil-breaking plate 34. A locking slider 38 is rotatably installed below the lifting screw 39. The locking slider 38 is slidably connected to the groove 35. A sampling through hole 21 is provided below the bottom plate 11. A slot 22 corresponding to the stabilizing plate 33 is provided on the bottom plate 11. When the device is fixed, the reinforcing screw 37, which is inclinedly installed on the bottom plate 11, is inserted into the groove 35 of the soil-breaking plate 34 through the positioning rod sleeve 36. Then, the lifting screw 39 at the upper end of the soil-breaking plate 34 is rotated so that the locking slider 38 moves downward through the groove 35 and locks and fixes with the reinforcing screw 37. The soil-breaking plate 34 and the reinforcing screw 37 are fixed crosswise.

[0027] The working principle and usage process of this utility model are as follows: By setting up a support mechanism 10 and a fixing mechanism 9, when the device is sampling, the stiffening plate 12 on the base plate 11 reinforces and supports the sampling mechanism 2. The positioning pin 42 at the bottom of the base plate 11 rotates to be vertical to the ground and inserts into the ground to position and fix the device. The rotating screw 32 on the base plate 11 rotates to move the stabilizing plate 33 downward, thereby driving the soil breaking plate 34 to break the soil downward. Then, the reinforcing screw 37 is rotated and inserted obliquely downward into the groove 35 of the soil breaking plate 34. Then, the lifting screw 39 at the upper end of the soil breaking plate 34 is rotated to push the locking slider 38 downward and lock the reinforcing screw 37, so that the soil breaking plate 34 and the reinforcing screw 37 are cross-fixed, thereby improving the stability of the device operation.
