[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1-Figure 3 After the drill bit 3 enters the soil, the drill pipe 2 will follow and enter, and the inner sleeve of the drill pipe 2 is provided with a collector 4. The collector 4 includes a collecting rod and a partition. The number of partitions is several, and the several partitions are fixedly connected to the outer side of the collecting rod in a linear array in the up and down directions. The outer wall of the partition fits with the inner wall of the drill pipe 2, and the bottom end of the drill pipe 2 is divided into multiple sampling spaces. The front side surface of the drill pipe 2 is provided with a sampling port 5, and the front side surface of each sampling space is provided with a sampling port 5. The following structures are all arranged in the first sampling port 5 at the top.

[0035] Reference Figure 4-Figure 6 The right side of the inner bottom surface of the sampling port 5 is rotatably connected with a rotating rod 6, the top of the rotating rod 6 passes through the drill rod 2, and the outer side of the rotating rod 6 is fixedly connected with a sealing arc plate 7. When the rotating rod 6 rotates, it can drive the sealing arc plate 7 to move synchronously. In the initial state, the sealing arc plate 7 can seal the inside of the sampling port 5 to prevent the soil above from entering the space where the soil below needs to be sampled when the drill bit 3 enters the soil for drilling, thereby affecting the detection results. The outer wall of the sealing arc plate 7 fits the inner wall of the sampling port 5.

[0036] The top of the sealing arc plate 7 is provided with a limiting unit, which is used for the fixed limit of the sealing arc plate 7. The limiting unit includes a groove 71, which is opened on the inner top surface of the sampling port 5. The inner bottom surface of the groove 71 is fixedly connected to a spring 72, and the bottom end of the spring 72 is fixedly connected to a sealing plate 73. The sealing plate 73 can seal the inner upper end of the groove 71 to prevent soil from entering therein, thereby preventing soil from adhering to the spring 72 and affecting its use. The outer wall of the sealing plate 73 fits with the inner wall of the groove 71. When the sealing plate 73 moves upward, it can squeeze the spring 72, so that the spring 72 is compressed to generate elastic potential energy. The bottom end of the sealing plate 73 is fixedly connected to a block 7 The top of the sealing plate 73 is fixedly connected to the connecting rod 75. When the connecting rod 75 moves upward, the sealing plate 73 can be driven to move synchronously. The top of the connecting rod 75 passes through the drill pipe 2. The tops of the connecting rod 75 and the rotating rod 6 are fixedly connected to handles. The staff can use the handles to quickly and conveniently operate the connecting rod 75 and the rotating rod 6. A circular hole 76 is provided on the upper surface of the sealing arc plate 7. The blocking block 74 is clamped inside the circular hole 76. The back of the sealing arc plate 7 is fixedly connected to the limiting cylinder 8. The blocking block 74 enters the limiting cylinder 8 to clamp and fix the sealing arc plate 7, so that the sealing arc plate 7 is stably maintained in the state of opening the sampling port 5.

[0037] When the drill rod 2 is in the state of initialization, the card block 74 is located inside the circular hole 76 to clamp and fix the sealing arc plate 7, which can seal the interior of the sampling port 5 to prevent the soil above from entering the sampling space below when the drill rod 2 enters the soil. When the sampling port 5 needs to be opened for sampling, the rotating rod 6 can be rotated to drive the sealing arc plate 7 to rotate forward to open the sampling port 5. At the same time, the left end of the opened sealing arc plate 7 will flip forward and move to the outside of the sampling port 5. At this time, when the drill rod 2 rotates, it can drive the sealing arc plate 7 to move to scrape the soil and quickly enter the sampling space to prevent the soil from being too hard to enter the drill rod 2 through the sampling port 5 in large quantities, thereby affecting the sampling volume. The bottom end of the drill rod 2 can be set to the inside of the sampling port 5 at the bottom, and be rotatably connected to the inner bottom surface of the sampling port 5 at the bottom. When the drill rod 2 rotates, it can drive the sealing arc plates 7 at all sampling ports 5 to move.

[0038] Reference Figure 2 and Figure 7 , the front side of the upper surface of the drill rod 2 is fixedly connected with a magnetic plate 9, the front side of the upper surface of the drill rod 2 is fixedly connected with a limit rod 10, the outer side of the limit rod 10 is rotatably connected with a scraper 11, the scraper 11 can rotate around the limit rod 10, and the left surface of the scraper 11 fits with the outer wall of the collector 4. When the sampling is completed, the collector 4 moves upward and the scraper 11 can be rotated to enter the sampling space and rotate the collector 4. After the staff manually fixes the scraper 11 and rotates the collector 4, the scraper 11 can completely scrape the soil in the sampling space for collection and processing. The operation is simple and the limit rod 10 The top of the limit plate 12 is fixedly connected to the limit plate 12, and the limit plate 12 can limit the scraper 11 to prevent the limit plate 12 from being stuck and unable to move due to the upward and downward deviation when scraping the soil in the sampling space. The bottom end of the right surface of the limit rod 10 is fixedly connected to an iron sheet 13, and the bottom surface of the iron sheet 13 and the upper surface of the magnetic plate 9 are located in the same horizontal plane. During the sampling process, the scraper 11 can be rotated toward the back so that the iron sheet 13 moves to fit the upper surface of the magnetic plate 9. At this time, the magnetic plate 9 can limit and fix the iron sheet 13 and the scraper 11 to prevent the scraper 11 from shaking during the sampling process, which may affect the operation of the staff.

[0039] Working principle: Place the casing 1 on the ground, rotate the drill rod 2 to move downward so that the drill bit 3 enters the soil, and at the same time, after the drill rod 2 follows and enters the soil, pull the connecting rod 75 upward to drive the block 74 to move upward to release the clamping fixation of the sealing arc plate 7, loosen the connecting rod 75, rotate the rotating rod 6 to drive the sealing arc plate 7 to move forward to open the sampling port 5. During the rotation of the sealing arc plate 7, the block 74 can move downward under the elastic potential energy of the spring 72 and enter the limiting cylinder 8 to limit the sealing arc plate 7, so that the sealing arc plate 7 can be stably maintained in the state of opening the sampling port 5. At this time, when the drill rod 2 is rotated, the sealing arc plate 7 can scrape the soil, so that the soil can better enter the sampling space.
