Specifically, the above content is disclosed through the following examples.

As shown in the figure, Fig. 1-Fig. 10 is the first embodiment of the present invention, in Fig. 3 and Fig. 4 of this embodiment:

The inner cylinder 220 is located in the outer cylinder 210, and the bottom of the outer cylinder 210 is fixedly connected with a drill bit 212. The drill bit 212 is in a ring structure, and its bottom is in a sawtooth state, so as to drill the soil when rotating; the inner cylinder 220 includes a fixed ring 221, fixed The ring 221 is fixedly arranged on the top of the drill bit 212, the top of the fixed ring 221 is fixedly connected with a connecting shaft 223, and the top of the connecting shaft 223 is fixedly connected with a ring cover 222, and the top of the ring cover 222 is fixedly connected with the output shaft of the driving motor 113. A collar 224 is arranged vertically and rotated on the outer wall of the connecting shaft 223. Under normal circumstances, the fixed ring 221, the ring cover 222 and the collar 224 form a cylindrical structure, and the sleeve 231 limits the collar 224, so that The collar 224 cannot be displaced. When the drill bit 212 rotates, the soil is drilled into the cylindrical structure to complete the sampling work. When the casing 231 is separated from the outer wall of the collar 224, the driving motor 113 drives the ring cover 222 to rotate, and the ring cover 222 drives the drill bit 212 to rotate through the connecting shaft 223 and the fixed ring 221. At this time, under the action of inertia, part of the collar 224 will shake in the installation cavity 211 with the connecting shaft 223 as the axis (as shown in Figures 9 and 10 ), the shaken collar 224 is misaligned with other collars 224, and the sample inside the collar 224 is cut into multiple sections at this time.

In FIGS. 4-7 , the stopper 230 includes a connecting plate 233 and a plurality of bushings 231, and the number of the bushings 231 corresponds to the number of the collars 224, which means that the outer wall of each collar 224 is provided with a Sleeve 231, the sleeve 231 is slidingly sleeved on the outer wall of the collar 224, and there are multiple connecting plates 233, and the multiple connecting plates 233 are all rotatably arranged on the inner wall of the outer cylinder 210, specifically, the multiple connecting shafts 223 are arranged in an annular array set, and a plurality of connecting plates 233 are connected by a ring, and the inner wall of the outer cylinder 210 is provided with a rotating groove, and the ring is rotated and arranged in the rotating groove to realize the rotation of the connecting plates 233; at the same time, in order to meet the requirements of the casing 231 Reset, the outer wall of the casing 231 is fixedly connected with a slider 232, the connecting plate 233 is provided with a chute 234 close to the side wall of the sleeve 231, the slider 232 is longitudinally slidably arranged in the chute 234, and every two adjacent chute Return springs 235 are arranged between the grooves 234; but in order to realize the truncation of the sample, multiple sleeve pipes 231 need to be divided into two groups, and the return springs 235 cannot be arranged between the proximal ends of the two groups of sleeve pipes 231 (as shown in Figure 7). Shown), when working, the tension of the return spring 235 pushes the plurality of sleeves 231, so that each sleeve 231 slides to the outer wall of the corresponding collar 224. At this time, the inner sleeve 231 of the collar 224 is limited, and cannot Rotate through connecting shaft 223, so just can drill to a complete columnar sample, when sleeve pipe 231 is pushed by connecting block 242, return spring 235 is compressed, forces part of sleeve pipe 231 to move to the outer wall of other collar 224, cancels The limit of part collar 224 is fixed.

When the sample needs to be truncated, the collar 224 corresponding to the truncated part needs to be swung, which means that the sleeve 231 needs to be separated from a part of the collar 224. The way of detachment can be to use a hook tool to pull up or press down the corresponding sleeve 231 , but in order to control the sliding distance of the casing 231, please refer to Fig. 7 and Fig. 8, in this embodiment, the adjusting member 240 includes a threaded rod 241, and the outer wall of one end of the threaded rod 241 is rotated to be provided with a fixed plate 114, the fixed plate 114 is plugged and arranged on the outer wall of the hood, the other end of the threaded rod 241 penetrates into the installation cavity 211, and the outer wall of the threaded rod 241 is rotated to be provided with two connecting blocks 242, and one end of the connecting block 242 is in contact with the inner wall of the outer cylinder 210 to prevent When the threaded rod 241 rotates, the connecting block 242 is also rotated, and the other end is close to the outer wall of the collar 224, so that the sleeve pipe 231 on the outer wall of the collar 224 can be pushed to move when the connecting block 242 moves, so that the position of the sleeve pipe 231 is adjusted. At the same time, the threads on the outer walls at both ends of the threaded rod 241 are symmetrical. In this way, by turning the threaded rod 241, the two connecting blocks 242 are relatively moved, and the sleeve 231 is pushed during the movement, so that the limit of the collar 224 located in the middle part is canceled, which means that this part The collar 224 can deviate from the position of the collar 224 that is limited and fixed, so that the sample can be cut off, and the moving distance of the connecting block 242 can be known through the number of turns of the threaded rod 241, thereby improving the accuracy of the cut-off length of the sample. sex.

In addition, considering that the adjusting member 240 is located in the fixing ring 221 , in order to reduce the influence of the adjusting member 240 on the shaking of the collar 224 , the threaded rod 241 is arranged opposite to the connecting shaft 223 .

That is to say, by limiting the states of the multiple collars 224, the limit to the collars 224 is cancelled, and the collars 224 shake by the rotation of the ring cover 222 under the action of inertia, so that the multiple collars The position between 224 deviates, and when the deviation occurs, the sample is forced to be truncated, thereby avoiding the dependence on cutting equipment and reducing the number of tools carried.

But also can encounter a kind of situation in adopting process, just need the end soil of sample two ends exactly, the position in the middle does not need to use, for this reason, Fig. 4, Fig. 11 and Fig. 12 have shown the first method of the present invention In the second embodiment, in this embodiment, the unused soil is quickly processed to further increase the work efficiency of sampling personnel. Wherein, the bottom of connecting plate 233 is fixedly connected with rotating ring 250, and rotating ring 250 is arranged on the outer wall of fixed ring 221, and the outer wall of rotating ring 250 is fixedly provided with a plurality of material guide plates 251, and a plurality of material guide plates 251 are spiral And the annular array is arranged on the outer wall of the swivel ring 250. When part of the collar 224 continues to shake, the soil sample located in the collar 224 will gradually fall to the place of the installation cavity 211 under the action of continuous shaking, and then the fixed plate 114 is separated from the hood, and the fixed plate 114 is rotated. At this time, the fixed plate 114 drives the threaded rod 241 to move in a circular path in the installation cavity 211. The threaded rod 241 contacts the connecting plate 233 and drives the connecting plate 233 during the movement. movement, the connecting plate 223 drives the swivel 250 to rotate, so that the material guide plate 251 crushes the soil sample to the bottom of the installation cavity 211, and then a discharge port 252 is opened on the outer wall of the outer cylinder 210, so that the soil at the bottom of the installation cavity 211 is under the centrifugal force Under the upward action, it is discharged through the discharge port 252. At the same time, in order to discharge the extruded soil and prevent the soil from continuously accumulating on the outer wall of the outer cylinder 210, resulting in the phenomenon that the subsequent soil cannot be discharged, a spiral plate 253 is arranged on the outer wall of the outer cylinder 210. At this time, in conjunction with the rotation of the outer cylinder 210, the soil on the outer wall of the outer cylinder 210 is discharged to the ground under the promotion of the rotation of the spiral plate 253.

It can be seen that by continuously acting on the collar 224, the swing time of the collar 224 is lengthened, forcing the sample in the collar 224 to fall into the installation cavity 211, and then the action of the material guide plate 251 and the spiral plate 253 will no longer need to be used. The sample is squeezed to the soil surface, allowing quick disposal of unused samples.

Considering that when coring, it is also a problem to take out the drilled sample from the soil, some soil will rub against the inner wall of the collar 224 when drilling, and the rotating collar 224 will reduce the diameter of the soil sample , resulting in a gap between the soil sample and the collar 224, so that the collar 224 drives the sample out of the soil. For this reason, Figures 13-16 are the third embodiment of the present invention, which is based on the second embodiment Carrying out the embodiment is mainly to increase the frictional force between the sample and the collar 224 to improve the efficiency of taking out the sample. In this example:

A filter screen 260 is arranged in the discharge port 252 to block the pebbles in the soil discharged through the discharge port 252. The outer wall of the fixed ring 221 is provided with a feed port 261, and the top of the swivel ring 250 is fixedly provided with a retaining ring. 262, there is a gap between the retaining ring 262 and the swivel ring 250, and a guide is provided between the swivel ring 250 and the fixed ring 221, and the guide will drive the swivel ring 250 to rise when the fixed ring 221 rotates, so that the swivel ring 250 and the retaining ring 250 The gap between the rings 262 moves to the feed port 261 .

The guide includes a guide groove 263 and a guide block 264. The guide groove 263 is set on the outer wall of the fixed ring 221. The guide groove 263 is in a spiral structure, and the top is an annular through groove. The guide block 264 is slidably arranged in the guide groove 263. The guide block 264 is fixedly arranged on the inner wall of the swivel ring 250. When the fixed ring 221 rotates, the swivel ring 250 rises and enters the annular through groove through the guidance of the guide groove 263, and the swivel ring 250 is in a static state. The ring 221 is in a rotating state, so the small stones that are blocked at the bottom of the installation cavity 211 (the small stones need to be piled up at a height greater than the rising height of the swivel ring 250, otherwise the small stones cannot contact the material guide plate 251) rotate at a high speed in the fixed ring 221 (The fixed ring 221 needs to maintain a relatively high rotational speed to allow small stones to rise through the slope of the material guide plate 251) under the action of contact with the material guide plate 251, and rise to the gap through the slope of the material guide plate 251. At the same time, the swivel ring 250 Drive the gap to rise to the feed inlet 261, some small stones will enter the inner wall of the fixed ring 221 through the gap and the feed inlet 261, and fill the gap, so that the friction between the sample and the fixed ring 221 becomes larger, so that The sample is clamped on the inner wall of the fixing ring 221, so that the sample is taken out from the soil. And in order to cooperate with the rise of the swivel ring 250 , a straight rod 265 is fixedly connected to the bottom of the connecting plate 233 , and one end of the straight rod 265 penetrates into the retaining ring 262 and is slidably connected with the retaining ring 262 .

To sum up, the small stones in the discharged soil are collected, and the small stones are sent to the gap with the rotation of the fixed ring 221. The small stones enter the inside of the fixed ring 221 through the gap and the feed port 261 to clean the outer wall of the sample. Filling increases the frictional force between the sample and the fixed ring 221, so that the sample is stuck on the inner wall of the fixed ring 221, thereby quickly taking the sample out of the soil.

The second object of the present invention is to provide a method for geological and mineral resource exploration rotary cutting sampling device, including the following method steps:

S1. The output shaft of the driving motor 113 drives the rotary cutting part 200 to rotate, the drill bit 212 drills the core to the ground, and then cooperates with the extension of the movable end of the hydraulic rod 112 to drive the driving motor 113 to move down. At this time, the driving motor 113 also drives the drill bit 212 down. This allows the inner barrel 220 to drill soil samples at different depths.

S2. The threaded rod 241 in the rotating state moves the two connecting blocks 242 relative to each other, and pushes the sleeve 231 during the movement, so that the sleeve 231 is separated from the collar 224. At this time, the position of the collar 224 of the disengagement part is limited got canceled;

S3. When the casing 231 is separated from the outer wall of part of the collar 224, the driving motor 113 drives the ring cover 222 to rotate, and the ring cover 222 drives the drill bit 212 to rotate through the connecting shaft 223 and the fixed ring 221. At this time, under the action of inertia, part of the collar 224 will shake in the installation cavity 211 with the connecting shaft 223 as the axis, and the shaken collar 224 and other collars 224 are misaligned with each other. At this time, the samples inside the collar 224 are cut into multiple sections.
