A pushing assembly 22 for providing power to the water intake cylinder 15 is provided in the drum 13. A threaded assembly 23 for providing power to the pushing assembly 22 is provided on the mounting ring 10. A lifting ring 24 for cooperating with the output shaft of the motor 12 is provided on the upper side of the drum 13. A rotating assembly 25 and a one-way assembly 26 for providing power to the threaded assembly 23 are provided on the lifting ring 24; the lifting component includes a telescopic assembly 30 arranged on the lifting ring 24, and a centrifugal assembly 31 for providing power for the lifting and lowering of the lifting ring 24 is provided on the output shaft of the motor 12.

[0030] Specifically, the outside of the boom here is connected to engineering machinery, the most common of which are engineering vehicles, excavators, etc. There is no specific restriction, as long as it can provide downward force for the boom and can move on relatively wet ground. The connection between the engineering machinery and the boom here is existing technology and will not be elaborated here. Of course, the boom here and the mounting ring 10 can also be fixed by means of mechanical claws. The method here is not unique, as long as a stable effect can be formed between the mounting ring 10 and the boom. The motor 12 here is a servo motor 12, and its speed is different when it is rotated forward and reversed. This is existing technology and will not be elaborated here. The model of the motor 12 is adapted according to the depth of the drum 13 driven into the ground, and is not limited here.

[0031] Furthermore, the guide assembly 20 includes an annular groove 201 provided on the mounting ring 10, the guide ring 21 cooperates with the annular groove 201, and the outer side wall and the lower side wall of the guide ring 21 are provided with balls 202 that cooperate with the annular groove 201; the ejection assembly 22 includes three L-shaped grooves 221 provided on the guide ring 21, the L-shaped groove 221 extends into the rotating drum 13, a slide plate 222 is slidably connected in the L-shaped groove 221, and a plurality of push plates 223 are fixedly connected to the slide plate 222, and the plurality of inner grooves 14 are divided into three rows, and the L-shaped groove 221 is connected to the inner groove 14 through a connecting groove, and the plurality of push plates 223 all extend into the inner groove 14 and are fixedly connected to the water intake cylinder 15, and the lower end of the rotating drum 13 is conical, and a reaming ring 224 is fixedly connected to the lower end of the rotating drum 13.

[0032] Among them, the setting of the ball 202 can reduce the friction resistance between the guide ring 21 and the inner wall of the annular groove 201, and extend the service life of the guide ring 21. The L-shaped groove 221 here can also be multiple, but not less than three, and there are no less than three water collection tubes 15 in a row, so that sampling can be carried out at multiple positions and multiple different depths to ensure the breadth and accuracy of sampling. Elastic rubber is provided in the inner groove 14 here, which can seal the upper end of the water collection tube 15 to prevent leakage of samples after sampling.

[0033] Preferably, the threaded assembly 23 includes three damping shafts 231 that penetrate and are rotatably connected to the mounting ring 10. The lower ends of the three damping shafts 231 are fixedly connected to a reciprocating screw 232. The guide ring 21 is provided with an annular opening 233. A transmission ring 234 is provided in the annular opening 233 without contact. The transmission ring 234 is slidably connected to the inner wall of the annular groove 201. The transmission ring 234 is threadedly connected to the reciprocating screw 232. The L-shaped groove 221 penetrates and is slidably connected to the transmission ring 234. The matching L-shaped plate 235 is elastically connected to the inner wall of the L-shaped groove 221 through a first spring 236. The front and rear side walls of the L-shaped plate 235 are provided with an oblique groove 237. The slide plate 222 is fixedly connected to a U-shaped plate 238. The U-shaped plate 238 is fixedly connected to a lever 239 that cooperates with the oblique groove 237. The projected length of the oblique groove 237 is greater than the length of the push plate 223, and the projected width of the oblique groove 237 is less than the distance from the U-shaped plate 238 to the bottom inner side of the L-shaped groove 221.

[0034] It should be noted that there are no less than three damping shafts 231 here, which drive the movement of the transmission ring 234 from three positions, so that the movement of the transmission ring 234 is more stable, and the L-shaped plate 235 is misaligned with the reciprocating screw 232, so that the reciprocating screw 232 and the L-shaped plate 235 will not collide. A guide block is provided on the L-shaped plate 235 here, and a guide groove that cooperates with the guide block is provided on the inner wall of the L-shaped groove 221, so as to guide the L-shaped plate 235 when it moves up and down.

[0035] Furthermore, the rotating assembly 25 includes a fixed ring 251 fixedly connected to the lifting ring 24, a plurality of clamping blocks 252 are provided on the fixed ring 251, a support plate 253 is fixedly connected to the damping shaft 231, and an extension block 254 that cooperates with the clamping block 252 is fixedly connected to the support plate 253; the one-way assembly 26 includes a receiving groove 261 set on the support plate 253, the extension block 254 is elastically connected to the inner wall of the receiving groove 261 through a second spring 262, and the extension block 254 and the clamping block 252 are provided with cutting edges 263 that cooperate with each other.

[0036] It should be noted that the setting of the cutting edge 263 here is that when the two cutting edges 263 are against each other, the extension block 254 will enter the accommodating groove 261 under the action of the extrusion force, and when the non-cutting edge 263 of the extension block 254 is against the non-cutting edge 263 of the clamping block 252, the lifting ring 24 drives the fixing ring 251 to rotate, and then drives the support plate 253 to rotate.

[0037] During use, when sampling harder soil, the motor 12 is turned on, and the output shaft of the motor 12 rotates clockwise (looking down at the direction of the motor 12, the same below) to drive the drum 13 to rotate. When the drum 13 rotates, the guide ring 21 moves in the annular groove 201 to guide the drum 13. After the rotation speed of the drum 13 stabilizes, the cone at the bottom of the drum 13 contacts the ground, and the movable arm provides downward pressure to drive the drum 13 into the ground. At this time, under the action of the extrusion force, the soil will enter the drum 13, and then the motor 12 stops. To stop the rotation, the boom lifts the mounting ring 10 to drive the guide ring 21 upward, and then drives the rotating drum 13 upward. When the rotating drum 13 moves to the upper side of the ground, the soil in the rotating drum 13 can be taken out. During this process, when the output shaft of the motor 12 rotates to drive the lifting ring 24 to rotate (in this embodiment, the output shaft of the motor 12 is fixed to the lifting ring 24), the cut edge 263 of the clamping block 252 on the fixing ring 251 cooperates with the cut edge 263 on the extension block 254, and will not drive the support plate 253 to rotate, and will not cause the damping shaft 231 to rotate;

[0038] When it is necessary to sample underground mud or water, the drum 13 is first moved to the required depth in the above manner. During this process, the expansion ring 224 acts to make the hole drilled by the drum 13 larger than the diameter of the drum 13, so as to prevent the surrounding soil from squeezing the water sampling cylinder 15 too much, causing the water sampling cylinder 15 to deform. When the drum 13 moves to the required position, the output shaft of the motor 12 is reversed. At this time, the lifting ring 24 rotates, driving the non-cutting edge 263 of the clamping block 252 on the fixing ring 251 to resist the non-cutting edge 263 of the extension block 254 on the support plate 253, which will drive the support plate 253 to rotate, and then drive the damping shaft 231 to rotate, so that the reciprocating screw 232 rotates, and drives the transmission ring 234 to move up and down. When the transmission ring 234 moves downward, it squeezes the L-shaped plate 235, so that the first The spring 236 is compressed, and when the L-shaped plate 235 moves downward, the lever 239 cooperates with the inclined slot 237. Here, the inclined slot 237 is higher on the left and lower on the right. When the L-shaped plate 235 moves downward, the lever 239 moves toward the L-shaped plate 235, the U-shaped plate 238 moves toward the L-shaped plate 235, and the slide plate 222 moves toward the L-shaped plate 235, so that the push plate 223 moves outward, driving the sampling tube to move outward to sample water or mud. It is worth noting that when the sampling tube moves outward, the inner end of the sampling tube is always in the inner groove 14, which will not cause mud to enter the inner groove 14 and affect the problem of resetting the sampling tube. At the same time, a bevel is provided on the sampling tube. At this time, the rotating drum 13 still rotates at a certain angle, and the bevel cooperates with the rotation to make the mud better enter the sampling tube.

[0039] The diameter of the fixed ring 251 here is much larger than the diameter of the support plate 253, and the number of the blocking blocks 252 on the fixed ring 251 is much larger than the number of the extending blocks 254 on the support plate 253. Therefore, when the reciprocating screw 232 drives the transmission ring 234 to reciprocate, the rotation angle of the lifting ring 24 is small, which will not cause excessive collision between the sampling tube and the underground soil. At the same time, the distance between the outer wall of the reaming ring 224 and the outer wall of the rotating cylinder 13 is less than the width of the sampling tube.

[0040] In summary, by setting up drilling components and transmission components, the forward and reverse rotation of the motor 12 can drive the drum 13 to sample harder soil, and through the pushing component 22, the sampling barrel can be automatically pushed out after the drum 13 enters the underground to sample mud or water, integrating the sampling of harder soil, mud and water into one, making the sampling range wider and the usage scenarios more extensive.

[0041] Example 2, reference Figures 1 to 7, which is the second embodiment of the present invention. Different from the previous embodiment, based on embodiment 1, this embodiment provides a lifting component of a deep water and soil sampling device for wetlands, which solves the problem of how to avoid the extension block 254 and the clamping block 252 from constantly colliding and causing large wear. It includes a telescopic assembly 30, including a cylinder 301 fixedly connected to the rotating drum 13, and a connecting column 302 is slidably connected inside the cylinder 301. The upper end of the connecting column 302 is fixedly connected to the lifting ring 24, and the connecting column 302 is elastically connected to the inner wall of the cylinder 301 through a third spring 303. The centrifugal assembly 31 includes a rigid rope 311 fixedly connected to the output shaft of the motor 12, and a counterweight ball 312 is fixedly connected to the rigid rope 311. The lifting ring 24 is provided with two strip openings 313 that cooperate with the rigid rope 311. The width of the strip opening 313 is smaller than the diameter of the counterweight ball 312, and the inner wall of the lifting ring 24 does not contact the output shaft of the motor 12.

[0042] Specifically, the width of the strip opening 313 is smaller than the diameter of the counterweight ball 312, so that when the counterweight ball 312 moves, the counterweight ball 312 will not move to the upper side of the lifting ring 24. At the same time, the diameter of the lifting ring 24 here is sufficient, and the counterweight ball 312 will not move to the outside of the lifting ring 24. In this embodiment, the inner wall of the lifting ring 24 does not contact the output shaft of the motor 12, thereby ensuring that the lifting ring 24 can perform lifting and lowering movements.

[0043] During use, when the output shaft of the motor 12 rotates clockwise, it is worth noting that the speed of the output shaft of the motor 12 is very fast when it rotates clockwise, and the speed is slow when the output shaft of the motor 12 rotates counterclockwise. Therefore, when the output shaft of the motor 12 rotates rapidly, the rigid rope 311 is driven to rotate rapidly around the output shaft of the motor 12. Under the action of centrifugal force, the rigid rope 311 slowly tends to be horizontal from tilt and maintains the stability of the horizontal state. In this process, the lifting ring 24 is driven upward, the connecting column 302 is driven upward, and the third spring 303 is extended, so that the fixing ring 251 is upward, and the block 252 is separated from the extension block 254, so that during the rotation process , the block 252 has no contact with the extension block 254, avoiding the block 252 and the extension block 254 from colliding with each other, reducing the wear between the block 252 and the extension block 254, and extending the service life of the block 252 and the extension block 254. It is worth noting that the motor 12 here rotates in a full circle, and the number of blocks 252 is large, so that when the lifting ring 24 is reset, the block 252 can continue to cooperate with the extension block 254. Here, the cylinder 301 is fixed to the rotating drum 13, so that the counterweight ball 312 rotates with the lifting ring 24, and the two are relatively stationary, thereby avoiding wear between the counterweight ball 312 and the lifting ring 24.

[0044] In summary, by setting up a lifting component, when the output shaft of the motor 12 rotates, under the action of centrifugal force, it can also drive the rigid rope 311 to slowly change from an inclined state to a horizontal state, so that the lifting ring 24 moves upward, driving the clamping block 252 on the fixed ring 251 to separate from the extension block 254, avoiding the clamping block 252 and the extension block 254 from constantly colliding, and extending the service life of the clamping block 252 and the extension block 254.

[0045] Example 3 is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a sampling method for engineering machinery, which includes:

[0046] S1: Fix the mounting ring 10 to the boom on the construction machinery (construction crawler vehicle, etc.);

[0049] S4: If the soil fluidity is low, the drum 13 can be directly pulled out;
