It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0035] It can be understood that the terms "first" and "second" used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0036] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0037] like Figures 1 to 4 As shown, a soil sampling device for construction investigation provided by an embodiment of the utility model includes:

[0038] A fixed frame 1, on which a feeding assembly 2 and a drilling assembly 3 are mounted, and the drilling assembly 3 moves relative to the fixed frame 1 through the feeding assembly 2;

[0039] A sampling assembly 5 is installed on the drilling assembly 3, and a plurality of sampling assemblies 5 are evenly distributed along the length of the drilling assembly 3, and are used to sample soil at different depths;

[0040] The sampling assembly 5 comprises:

[0041] A fixer 51 is provided on the drilling assembly 3;

[0042] The slider 52 is slidably matched with the fixture 51;

[0043] The sampler 53 is plugged into the slider 52 and is also slidably matched with the holder 51;

[0044] A reset spring 54 is connected to the fixer 51 and the slider 52 respectively, and is used to reset the slider 52;

[0045] The reset column 55 is fixedly mounted on the slider 52, and an electromagnet is also mounted on the reset column 55 for magnetically cooperating with the sampler 53;

[0046] The fixed wheel 56 is rotatably engaged with the reset column 55 .

[0047] In the embodiment of the utility model, in actual application, the drilling component 3 and the sampling component 5 will be driven by the feeding component 2, and the drilling component 3 will drill the soil to insert the sampling component 5 into the soil, and the fixed wheel 56 will be subjected to the force applied by the drilling component 3, so that the fixed wheel 56 will push the sampler 53 through the reset column 55, and the sampler 53 will be inserted into the soil. Several samplers 53 can sample soils of different depths in the same position, and then when the fixed wheel 56 is not subjected to the squeezing and pushing force, the sampler 53 is reset by the reset spring 54, and after the sampling component 5 is moved out of the soil, the sampler 53 is pushed out, and then the electromagnet is powered off to release the magnetic adsorption with the sampler 53, so as to facilitate the rapid disassembly of the sampler 53.

[0048] By setting up the sampling component 5, it is possible to sample soil at different depths at the same soil position, so that the sampled soil has an obvious contrast effect, and there is no need to sample the soil multiple times, which reduces the labor intensity of operators, improves the efficiency of soil sampling for construction surveys, and also improves the effect of soil sampling surveys.

[0049] like Figure 1 As shown, as a further embodiment of the present invention, the feeding assembly 2 includes:

[0050] The air feeding cylinder 21 is fixedly mounted on the fixing frame 1 and is used to move the drilling assembly 3;

[0051] The support frame 22 is fixedly mounted on the output shaft of the feed cylinder 21, and the support frame 22 is also slidably matched with the fixing frame 1 through the slide groove 11 provided on the fixing frame 1;

[0052] In the embodiment of the utility model, in actual application, the air cylinder 21 outputs power so that the support frame 22 adjusts the position of the drilling component 3 and the sampling component 5 to sample the soil, and the slide 11 increases the stability of the support frame 22 when it moves.

[0053] like Figure 2 and Figure 3 As shown, as a further embodiment of the present invention, the drilling assembly 3 includes:

[0058] Specifically, as a further embodiment of the present invention, the push block 36 is in the shape of a triangle, and is used to squeeze and push the fixed wheel 56;

[0059] In the embodiment of the utility model, in actual application, the motor 31 drives the drill 32 and the drilling head 33, and when the feed component 2 applies power, the soil is drilled to facilitate the insertion of the sampler 53 into the soil, and the effect of soil sampling is better. The pushing cylinder 34 can move the pushing frame 35, and the force of the moving push block 36 is used to apply force to the fixed wheel 56, so that the fixed wheel 56 inserts the sampler 53 into the soil through the reset column 55. Soil at different depths can be sampled at the same time, thereby improving the effect of soil sampling and making the sampled soil have a contrast effect.

[0061] Specifically, as a further embodiment of the present utility model, a fixed ruler 7 is also fixedly mounted on the fixed frame 1, and a scale mark for measuring the soil sampling depth is provided on the fixed ruler 7;

[0062] In the embodiment of the utility model, in actual application, since the fixed mark 6 will move synchronously with the support frame 22, it can cooperate with the fixed ruler 7 to measure the depth of the sampler 53 inserted into the soil, which is convenient for the staff to observe and determine the distance between the sampled soil and the ground.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
