Specific embodiments

[0041] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.

[0042] Reference Figures 1-9 , the specific embodiment of the present utility model provides an improved soil - subgrade core - drilling and sampling cutting cylinder, including:

[0043] Cutting cylinder 1;

[0044] Arc - shaped rotary cutter 2, a plurality of arc - shaped rotary cutters 2 are circumferentially and equidistantly arranged at the cutting edge of the cutting cylinder 1 and are rotationally connected to the cutting cylinder 1;

[0045] Rotation controller 3, a plurality of rotation controllers 3 are installed at the power input edge of the cutting cylinder 1, and the angles of a plurality of arc - shaped rotary cutters 2 are adjusted by the rotation controller 3.

[0046] In the existing core - drilling and sampling machine, the equipment is relatively simple, consisting of a frame structure, a diesel engine, and a core - drilling cylinder; when taking the core sample of the subgrade by core - drilling, it is not easy to take out the core sample because the bottom is still connected to the foundation, making it difficult to obtain the core sample. In this application, when the core - drilling cylinder drills to a certain depth, the core - drilling cylinder is taken out and replaced with the cutting cylinder 1. The main function of the arc - shaped rotary cutter 2 is to rotate along with the driving of the cutting cylinder 1 to cut the bottom of the core sample; the main function of the rotation controller 3 is to continuously adjust the angles of all arc - shaped rotary cutters 2 during the process of cutting the core sample, that is, to adjust the cutting depth of the arc - shaped rotary cutter 2 until the part of the bottom of the core sample connected to the foundation is cut open, facilitating the extraction of the core sample. Overall, this application can quickly and effectively cut the bottom of the core sample and reduce the difficulty of taking out the core sample.

[0047] For a further optimized solution, the rotation controller 3 includes:

[0048] A rotation control member is installed at the edge of the power input end of the cutting cylinder 1.

[0049] A rotating screw 5, the first end of the rotating screw 5 passes through the side wall of the cutting cylinder 1 along the axis and rotates synchronously with the arc-shaped rotating tool 2. The rotating screw 5 adjusts the angle through the rotation control member.

[0050] In the initial state, all the arc-shaped rotating tools 2 are distributed along the edge of the end face of the cutting cylinder 1 to form an annular structure, as Figure 9 shown; by manually operating the rotation control member, the arc-shaped rotating tool 2 is driven by the rotating screw 5 to rotate a certain angle towards the axis of the cutting cylinder 1, and then the cutting is started.

[0051] For a further optimized solution, the rotation control member includes:

[0052] A rotation controller plate body 31, the rotation controller plate body 31 is fixedly connected to the cutting cylinder 1, and the second end of the rotating screw 5 passes through the rotation controller plate body 31.

[0053] A clamping plate 33, the first ends of two groups of clamping plates 33 are rotatably connected inside the rotation controller plate body 31, and the second end of the first group of clamping plates 33 is clamped on the side wall of the rotating screw 5 along the tangent direction.

[0054] The second end of the first group of clamping plates 33 is clamped on the side wall of the rotating screw 5 along the tangent direction, so that the rotating screw 5 and the arc-shaped rotating tool 2 cannot rotate in the direction away from the bottom of the core sample, and the cutting angle of the arc-shaped rotating tool 2 can be maintained.

[0055] For a further optimized solution, it further includes:

[0056] A spring 32, several springs 32 are abutted between the two groups of clamping plates 33 and the inner side wall of the rotation controller plate body 31, and are located on the side of the two groups of clamping plates 33 away from the rotating screw 5.

[0057] A clamping plate control plate 34, the clamping plate control plate 34 is slidably connected to the rotation controller plate body 31, the clamping plate control plate 34 is located between the two groups of clamping plates 33, and abuts against the second group of clamping plates 33 on the rotation controller plate body 31 through the spring 32.

[0058] As Figure 5 shown, under the action of the resilience of the spring 32, the second group of clamping plates 33 (located on the Figure 5 left side in the figure) abuts against the clamping plate control plate 34. At this time, the second group of clamping plates 33 does not contact the rotating screw 5; under the action of the resilience of the spring 32, the first group of clamping plates 33 is clamped on the side wall of the rotating screw 5, so that the rotating screw 5 cannot rotate counterclockwise, that is, the arc-shaped rotating tool 2 cannot rotate in the direction away from the core sample.

[0059] The further optimization solution also includes:

[0060] A concave chute is provided on the rotating controller plate body 31. The clamping plate control plate 34 is slidably connected in the concave chute and abuts against the second group of clamping plates 33 through a spring 32 at one end of the concave chute away from the first group of clamping plates 33.

[0061] A serrated shaft portion 52 is provided for the portion of the rotating screw 5 located within the rotating controller plate body 31. The second end of the first group of clamping plates 33 abuts against the teeth of the serrated shaft portion 52 along the tangential direction to achieve a clamping effect.

[0062] Rotate the rotating screw 5 clockwise to drive the arc-shaped rotating cutter 2 to rotate towards the core sample, that is, to increase the cutting depth at the bottom of the core sample. During this process, the second group of clamping plates 33 are caught between the teeth of other serrated shaft portions 52 and cannot rotate counterclockwise. That is, during the cutting process, it is ensured that the arc-shaped rotating cutter 2 always approaches the core sample to ensure the cutting effect.

[0063] The concave chute is as Figure 6 shown. When the clamping plate control plate 34 is located at the position of the concave chute as Figure 6 , that is, inside the left side of the concave chute, under the action of the spring 32, the second group of clamping plates 33 abut against the clamping plate control plate 34 along the left-to-right direction, making the clamping plate control plate 34 unable to slide downward, and the rotating screw 5 can rotate clockwise. At this time, it corresponds to the state in Figure 5 . When the clamping plate control plate 34 is manually slid to the inside of the right side of the concave chute, it abuts against the first group of clamping plates 33 (located on the right side in Figure 5 ), causing the second end of the first group of clamping plates 33 to disengage from the teeth of the serrated shaft portion 52. At the same time, under the action of the spring 32, the second group of clamping plates 33 abut against the teeth of the serrated shaft portion 52. That is, the second end of the second group of clamping plates 33 abuts against the teeth of the serrated shaft portion 52 on the rotating screw 5 along the tangential direction under the resilience of the spring 32 to achieve a clamping effect, making the rotating screw 5 unable to rotate clockwise. At this time, the rotating screw 5 can be rotated counterclockwise to drive the arc-shaped rotating cutter 2 to rotate away from the core sample.

[0064] The further optimization solution also includes:

[0065] A hexagonal shaft portion 51 is provided at both ends of the rotating screw 5. The first group of hexagonal shaft portions 51 pass through the hexagonal holes 22 on the arc-shaped rotating cutter 2 and rotate synchronously with the arc-shaped rotating cutter 2. The second group of hexagonal shaft portions 51 pass through the rotating controller plate body 31.

[0066] The further optimization solution also includes:

[0067] The middle part of the rotary screw 5 is provided with a circular shaft part 53, which is located between the first group of hexagonal shaft parts 51 and the serrated shaft part 52;

[0068] A plurality of cylindrical circular cavities 11 are axially formed in the side wall of the cutting cylinder 1, and the circular shaft part 53 is rotatably fitted in the cylindrical circular cavity 11.

[0069] A further optimized solution further includes:

[0070] The serrated cutter 21 is arranged on the inner side wall of the arc-shaped rotary cutter 2 and is arranged close to the axis of the cutting cylinder 1.

[0071] The main function of the serrated cutter 21 is to cut the bottom of the core sample as the cutting cylinder 1 and the arc-shaped rotary cutter 2 rotate.

[0072] A further optimized solution further includes:

[0073] The rotary screw clamping hole 54 is formed in the first group of hexagonal shaft parts 51 and is located on the side of the arc-shaped rotary cutter 2 away from the cutting cylinder 1;

[0074] The pin shaft is fixedly penetrated through the rotary screw clamping hole 54.

[0075] A further optimized solution further includes:

[0076] The rotary shaft 4 is coaxially and fixedly connected to the power input end of the cutting cylinder 1, and the rotary shaft 4 is detachably connected to the output shaft of the engine through a flange structure.

[0077] The overall working principle of this application is as follows:

[0078] Start the diesel engine to drive the rotary shaft 4, and the rotary shaft 4 drives the rotation of the core drilling cylinder (not shown in the figure); conduct core drilling sampling on the sampling ground. When the core drilling cylinder drills to a certain depth, remove the core drilling cylinder and replace it with the cutting cylinder 1 in the initial state, and place it inside the core sample just drilled by the core drilling cylinder; adjust the clamping plate control board 34 of the rotary controller 3 to the left card slot of the concave chute, and then adjust the angle of the arc-shaped rotary cutter 2, that is, adjust the arc-shaped rotary cutter 2 towards the direction close to the core sample, and perform rotary cutting. After rotary cutting dozens of times, adjust the angle of the arc-shaped rotary cutter 2 again, and then perform rotary cutting; after rotary cutting dozens of times, repeat several times, the part connecting the bottom of the core sample and the foundation can be cut open, and then lift out the cutting cylinder 1. At this time, the arc-shaped rotary cutter 2 maintains the cutting angle, and the cut core sample can be taken out; adjust the clamping plate control board 34 of the rotary controller 3 to the right card slot, and restore the arc-shaped rotary cutter 2 to the bottom edge of the cutting cylinder 1, and the core sample can be taken out from the cutting cylinder 1.
