[0054] Embodiment two;

[0055] On the basis of the embodiment one, the preferred embodiment of the backfill soil ramming and sampling detection device provided by the application is as follows Figures 1-10As shown: the sampler 1 includes sampler main body 101, the outer wall of sampler main body 101 is symmetrically provided with two outer sliding grooves 103, the inner wall bottom of outer sliding groove 103 is embedded with sensor 104, the inner wall of sampler main body 101 is provided with several auxiliary impact mechanisms 106, the bottom of sampler main body 101 is fixedly connected with stable plug-in bottom 105, and the two sides of sampler main body 101 are symmetrically provided with side buffer springs 102.

[0056] The side buffer spring 102 is a steel plate spring, and a flat base is welded to the bottom of the side buffer spring 102.

[0057] The stable plug-in bottom 105 includes a bottom plug 1051 welded to the bottom of the sampler main body 101, a plurality of stabilizing blocks 1052 are equidistantly arranged on the outer wall of the bottom plug 1051, the stabilizing blocks 1052 are inclinedly arranged, and the stabilizing blocks 1052 are upwardly curved, and gaps are formed between the stabilizing blocks 1052.

[0058] In this embodiment, when the sampler main body 101 is inserted into the soil to the deepest part, the steel plate spring can achieve the effect of buffering and limiting the sampler main body 101, so as to avoid the sampler main body 101 from being excessively inserted into the soil, thereby avoiding the organic matter and water in the soil from entering the electrical mechanism above the sampler main body 101, and thereby causing damage to the electrical mechanism above the sampler main body 101. Compared with the fixed limiting mechanism, the steel plate spring has a better buffering effect, effectively reducing the impact force between the upper end of the sampler main body 101 and the ground, and thereby achieving the protection effect of the sampler main body 101 and the driving hydraulic cylinder 4 and other mechanisms above.

[0059] In this embodiment, the stable plug-in bottom 105 at the bottom of the sampler main body 101 first contacts the soil surface after being cleaned, the bottom plug 1051 is overall inverted conical, and during the falling process of the sampler main body 101, the insertion pressure is reduced, and the bottom plug 1051 is better inserted into the soil layer. The stabilizing blocks 1052 arranged on the outer wall of the bottom plug 1051 increase the ground gripping contact area with the ground, reduce the sliding of the sampler main body 101 during insertion into the soil layer, and ensure that the sampler main body 101 is stably inserted into the coating layer. The stabilizing blocks 1052 are dispersedly arranged, the resistance of the sampler main body 101 to the ground is reduced, and the sampler main body 101 is favorably inserted into the soil.

[0060] Example three;

[0061] On the basis of example one, the preferred embodiment of the backfill soil ramming sampling detection device provided by the application is as follows Figures 1-10As shown: the auxiliary impact mechanism 106 includes an inner chute 1061 opened in the inner wall of the sampler body 101, the inner wall of the inner chute 1061 is provided with a spring chuck, the outer wall of the spring chuck is clamped with a clamping seat 1064, the bottom of the clamping seat 1064 is fixedly connected with an impact block 1062, and the outer wall of the clamping seat 1064 is fixedly connected with a sharp insertion plate 1063.

[0062] In this embodiment, when the sampler body 101 gradually proceeds in the soil, because the backfill soil is mixed with gravel, when the sampler body 101 encounters the situation of being blocked by small stones, the sampler body 101 stops while generating an impact force, the impact force opens the connection between the spring chuck and the clamping seat 1064 in the auxiliary impact mechanism 106, the auxiliary impact mechanism 106 falls, the sharp insertion plate 1063 falls quickly under the counterweight action of the impact block 1062, the sharp insertion plate 1063 is provided with sharp surfaces on both sides, which can reduce resistance and smoothly reach above the small stones and extrude the small stones to both sides, the sampler body 101 can continue to move downward for sampling, the situation that the sampler body 101 continues to directly resist the small stones is reduced, and the bottom of the inverted cone-shaped bottom provided on the sampler body 101 is bent and deformed, thereby ensuring the amount of the sampling sample and the sampling position of the sample.

[0063] In order to facilitate the understanding of the above technical solutions of the present application, the working principle or operation mode of the present application in the actual process will be described in detail.

[0064] In actual application, in use: by fixing the installation hanger 5 on the mechanism of the mobile device or the mechanical hand and moving the sampling detection device to the selected backfill soil sampling position, the sampler 1 is lowered for sampling by controlling the four driving hydraulic cylinders 4:

[0065] The sampler body 101 falls vertically and enters the backfill soil under the pressure of the driving hydraulic cylinder 4;

[0066] In the state that the sampler 1 is vertically placed, the soil sample floating layer cleaning assembly 2 falls along the outer chute 103 outside the sampler 1 under the action of gravity, the soil sample floating layer cleaning assembly 2 is provided with a pressing and rotating mechanism 203 inside, and the upper weight block 202 provided on the inner sliding seat 201 contacts the ground with the bottom cleaning head 204 of the soil sample floating layer cleaning assembly 2 during the sampling process of the sampler 1, at this time, the sampler 1 continues to fall, the cleaning head 204 is mechanically linked with the pressing and rotating mechanism 203, and the cleaning head 204 experiences the following process under the action of the pressing and rotating mechanism 203: initial state:

[0067] The limiting sliding block is located at the top of the vertical chute 2034, the pressing spring 2032 is in a natural stretching state, and the cleaning head 204 is suspended;

[0068] The pressing stage:

[0069] External force presses the upper weight 202 → the upper pressing cylinder 2031 moves down → the limiting slider slides down along the vertical sliding groove 2034 → the cleaning head 204 directly contacts the surface of the soil sample, at this time there is no rotation;

[0070] Rotary trigger stage:

[0071] When the limiting slider reaches the bottom end of the vertical sliding groove 2034, it enters the spiral sliding groove 2033 → under the action of continuous downward pressure, the limiting slider moves along the spiral track → forcing the lower rotating cylinder 2035 to rotate relative to the upper pressing cylinder → driving the cleaning head 204 to rotate;

[0072] Reset stage:

[0073] Remove the external force → the pressing spring 2032 rebounds → pushes the upper pressing cylinder 2031 to move up → the limiting slider moves in the reverse direction along the spiral sliding groove 2033 to the vertical sliding groove 2034 → finally resets to the initial position;

[0074] After the soil sample floating layer cleaning assembly 2 cleans the ground during the vertical falling of the sampler main body 101, the sampler main body 101 continues to fall, at this time the soil sample floating layer cleaning assembly 2 slides along the inner wall of the outer sliding groove 103 and is finally left on the soil surface by the soil layer, the soil sample floating layer cleaning assembly 2 is above the sampler main body 101 relative to the sampler main body 101;

[0075] Before the sampler body 101 is inserted into the soil, the sensor 104 on the inner wall of the outer chute 103 is powered off, and when the sampler body 101 is inserted into the soil, the sensor 104 is powered on to start working. When the sampler body 101 is pulled up after taking the sample, the soil sample floating layer cleaning assembly 2 is slowly moved downward relative to the sampler body 101. When the soil sample floating layer cleaning assembly 2 contacts the bottom of the inner wall of the outer chute 103, the sensor 104 is triggered, and the take-up motor 306 on the sampler cleaning assembly 3 is turned on: the take-up motor 306 rotates the connecting rotating seat 303 through the winding and pulling rope, and then rotates the dust removal and shaking mechanism 301 and the inner cleaning scraper mechanism 302 on the connecting rotating seat 303: when the connecting rotating seat 303 rotates, the inner cleaning scraper mechanism 302 is vertically arranged and vertically arranged above the sampler body 101. When the sampler body 101 moves upward through the driving hydraulic cylinder 4, the sampler body 101 moves relative to the inner scraper 3021 and the elastic contact head 3023, and the thin scraper head 3022 and the elastic contact head 3023 on the inner scraper 3021 clean the inner wall of the sampler body 101: the inner cleaning scraper mechanism 302: the thin blade of the thin scraper head 3022 is formed by single-sided straight chamfering, and the inner wall of the sampler body 101 is scraped off; the elastic contact head 3023 buffers the pressure to prevent scratching the wall; at this time, the outer wall corrugated groove 3014 of the shaking baffle 3011 is lapped with the outer wall of the sampler body 101; every time the sampler body 101 continues to move upward, the shaking baffle 3011 and the sampler body 101 move relative to each other, slightly collide and vibrate, and the soil particles on the sampler body 101 that are not scraped off are vibrated and fallen off, increasing the cleaning effect of the sampler body 101;
