However, the above patent document still has the following defects during use:

[0004] During use, the above patent document uses spiral blades to transport soil from underground into the collection box. During the transportation, soils from different heights are mixed together.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, a sampling device for environmental engineering detection includes two support plates 1, the front and rear parts of the lower ends of the two support plates 1 are fixedly connected with support columns 2, the outer surfaces of the two support columns 2 on the same side that are close to each other are commonly fixedly connected with a support assembly 4, the lower parts of the outer surfaces of the four support columns 2 are commonly fixedly connected with a connecting frame 3, the inner surface of the connecting frame 3 is movably connected with a sampling tube 6, the inner surface of the sampling tube 6 is slidably connected with a feeding assembly 5, the middle parts of the ends of the two support plates 1 that are close to each other are commonly fixedly connected with a support rod 8, and the middle part of the outer surface of the support rod 8 is fixedly connected with a hydraulic cylinder 7.

[0027] The connecting rod 52 on the left side is in close contact with the front wall of the inner surface of the through slot 64 on the same side, and the connecting rod 52 on the right side is in close contact with the rear wall of the through slot 64 on the same side, which is the initial state.

[0028] The initial state of the middle circular plate 51 is that it is located at the lower part of the inner surface of the sampling tube 6 .

[0029] In the specific implementation process of the utility model, the staff first uses the support assembly 4 to move the device to the specific position of the sampling site, inserts the four support columns 2 into the ground, fixes the position of the device, keeps the position of the material discharge assembly 5 located at the lower side of the inside of the sampling tube 6 unchanged, and uses the components on the support assembly 4 to fix the position of the material discharge assembly 5, then starts the hydraulic cylinder 7 to drive the sampling tube 6 to move downward, fills the inside of the sampling tube 6 with soil, at this time the material discharge assembly 5 is located at the upper part of the inner surface of the sampling tube 6, then drives the sampling tube 6 to rotate a certain angle with the cooperation of the limit rod 31, and separates the soil column inside the sampling tube 6 from the underground soil;

[0030] Then, the fixing of the material discharge component 5 is released, and the hydraulic cylinder 7 is started again to drive the sampling tube 6 and the material discharge component 5 to move upward together, and the sampling tube 6 is taken out from the ground. Then, the position of the material discharge component 5 is fixed again by the support component 4, and the sampling tube 6 is driven downward by the hydraulic cylinder 7 again, and the soil column is pushed down by the material discharge component 5, thus completing the soil sampling work.

[0031] Specifically, in order to prevent the soil from breaking incompletely underground and being unable to be pulled out of the ground smoothly, refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 The support assembly 4 includes a handle 41, a slide rod 42 is fixedly connected to the middle of the lower end of the handle 41 near the sampling tube 6, a through hole 43 penetrating the slide rod 42 is opened at the left end of the slide rod 42, and a fixing rod 44 is fixedly connected to the lower end of the slide rod 42;

[0032] For further information, see Figure 2 , the two handles 41 and the two fixing rods 44 are fixedly connected to the two supporting columns 2 on the same side at the upper and lower sides;

[0033] For further information, see Figure 3 The upper end of the sampling tube 6 is rotatably connected to a top plate 61, the middle of the upper end of the top plate 61 is fixedly connected to a connecting seat 62, a slide groove 63 is opened on the front of the outer surface of the sampling tube 6, and a through groove 64 is opened on the left front side and the right rear side of the outer surface of the sampling tube 6;

[0034] For further information, see Figure 3 , the connecting seat 62 is fixedly connected to the hydraulic cylinder 7;

[0035] For further information, see Figure 6 The middle part of the front side of the upper end of the connecting frame 3 is fixedly connected to the limiting rod 31 through a connecting plate, and the limiting rod 31 is slidably connected to the sliding groove 63;

[0036] It can be seen that after the device is fixed, the position of the material-discharging assembly 5 at the lower part of the inner surface of the sampling tube 6 is kept unchanged, and the hydraulic cylinder 7 is started to drive the connecting seat 62 and the top plate 61 to move downward, so that the sampling tube 6 moves downward accordingly, and the sawtooth part at the lower end of the sampling tube 6 is used to cut the soil surface, and the inside of the sampling tube 6 is gradually filled with soil. In this process, the position of the material-discharging assembly 5 on the inner surface of the sampling tube 6 gradually moves upward;

[0037] In addition, when the sampling tube 6 moves downward, the limiting rod 31 slides on the inner surface of the slide groove 63. When the limiting rod 31 slides to the slide groove 63 until the sampling tube 6 drops to a certain height, the material discharge assembly 5 is located at the upper inner surface of the sampling tube 6. When the limiting rod 31 slides to the arc-shaped portion at the upper part of the slide groove 63, the sampling tube 6, the top plate 61 and the connecting seat 62 will all rotate clockwise by a certain angle, and the soil at the lower end of the sampling tube 6 will be cut off by the soil's compressive resistance but not torsion resistance, so that the sampling tube 6 can drive the soil column to be smoothly pulled out of the ground.

[0038] In the process of pulling out the soil column, the fixing of the feeding assembly 5 is released, and then the hydraulic cylinder 7 is started to drive the sampling tube 6 to move upward. The friction between the inner surface of the sampling tube 6 and the soil column is used to drive the sampling tube 6 and the soil inside to move a certain distance away from the ground. At this time, the feeding assembly 5 is still located on the upper inner surface of the sampling tube 6. Then the feeding assembly 5 is fixed on the slide bar 42, and the hydraulic cylinder 7 is used again to push the sampling tube 6 downward. The feeding assembly 5 is used to push the soil column out of the sampling tube 6. In this process, the integrity of the soil column is guaranteed, which is convenient for subsequent detection and research.

[0039] Specifically, in order to facilitate the removal of the sampled soil column and ensure its integrity, refer to Figure 3 and Figure 4The blanking assembly 5 includes a circular plate 51, the left and right parts of the outer surface of the circular plate 51 are fixedly connected with connecting rods 52, the ends of the two connecting rods 52 that are away from each other are fixedly connected with a slide plate 54, and the inner surfaces of the two through holes 43 at the bottom are provided with latches 53 that penetrate the slide plate 54 and are slidably connected with the slide plate 54;

[0040] For further information, see Figure 3 , the circular plate 51 is slidably connected to the sampling tube 6, and the two connecting rods 52 are slidably connected to the sliding rod 42 on the same side;

[0041] It can be seen that the connecting rod 52 on the same side can be fixed to the handle 41 on the same side by inserting the two latches 53 into the through holes 43 and passing through the slide plate 54, so as to fix the position of the circular plate 51 inside the sampling tube 6 to avoid affecting the collection of soil. In the process of taking out soil from the sampling tube 6, the slide plate 54 is fixed at the upper end of the handle 41 by the latch 53 again to keep the circular plate 51 at the upper side of the sampling tube 6. Then the hydraulic cylinder 7 is started to drive the sampling tube 6 to move downward. A staff member catches it under the sampling tube 6 and pushes the soil column down by using the circular plate 51, thus completing the soil sampling work and ensuring the integrity of the soil column, which is convenient for subsequent stratification detection.

[0042] During the rotation of the sampling tube 6, the two through slots 64 are opened at the center offset. After rotation, the connecting rod 52 on the right side will be tightly attached to the front side wall of the through slot 64 on the same side, and the connecting rod 52 on the left side will be tightly attached to the rear side wall of the through slot 64 on the same side, so that the sampling tube 6 can rotate smoothly.

[0043] It should be noted that the specific installation method of the hydraulic cylinder 7, the circuit connection method and the control method used in the present invention are all conventional designs, and the present invention will not elaborate on them in detail.

[0044] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
