[0003] After searching, Chinese patent publication number: CN218156969U discloses a sampling device for geological survey, which includes two rotating shafts and a hollow cylinder between the two rotating shafts. A spiral auger and a drill bit are provided on the lower rotating shaft. During the drilling process of the drill bit, due to the strip holes provided on the side of the hollow cylinder, the soil sample can enter the hollow cylinder during the rotation process. In this way, the rotation of the rotating shaft and the deposition of the soil sample will not be affected, and the sampling process is more reliable.

[0004] However, during actual use of the above-mentioned geological survey sample collector, when the drill bit is screwed into the soil to drill a hole, the soil on the inner wall of the hole will be squeezed, which will cause the soil inside the hole to harden. As the hollow cylinder enters the hole, the soil at the required sampling position is not loose enough to slide naturally, and it will be impossible to enter the hollow cylinder to complete the sampling, which affects the sampling effect. Therefore, a geological survey sample collector is proposed to solve the above problem. Utility Model Content

[0023] Reference Figure 1The present invention provides an embodiment of a geological survey sample collector, comprising a mounting base 1, a movable frame 2 is slidably connected to the interior of the mounting base 1, and a motor 3 is fixedly connected to the upper surface of the movable frame 2. The bottom output end of the motor 3 passes through the movable frame 2, and the bottom output end of the motor 3 is fixedly connected to a sampling tube 4. The bottom end of the sampling tube 4 is fixedly connected to a drill bit 5. When the motor 3 is started, it can drive the sampling tube 4 and the drill bit 5 to rotate. When sampling is required, the movable frame 2 can be pressed down and the motor 3 can be started, so that the drill bit 5 moves downward to drill into the soil. A spiral auger is fixedly connected to the connection between the drill bit 5 and the sampling tube 4 above the drill bit 5, which can expand the edge of the hole and discharge the soil sample upward. This is a prior art means in this field and will not be described in detail here.

[0024] Reference Figure 2-Figure 4 A sampling port 6 is provided on the right surface of the sampling tube 4. When the drilling is completed and the sampling tube 4 reaches the desired position, the soil to be sampled can enter the interior of the sampling tube 4 through the sampling port 6. A scraper 7 is provided inside the sampling port 6. The outer wall of the scraper 7 fits the inner wall of the sampling port 6, and the rear end of the scraper 7 is chamfered. In the initial state, the scraper 7 is located inside the sampling port 6, and the sampling port 6 can be sealed to prevent the soil in the upper layer from entering the sampling tube 4 during the process of the sampling tube 4 entering the hole, thereby affecting the sampling accuracy.

[0025] A rotating unit is provided on the outside of the scraper 7, and the rotating unit includes a driving motor 71 and a rotating rod 72. The driving motor 71 is fixedly connected to the upper surface of the sampling tube 4, and the rotating rod 72 is rotatably connected to the bottom surface of the sampling port 6. The upper end of the rotating rod 72 passes through the scraper 7, and the rotating rod 72 is fixedly connected to the scraper 7. When the rotating rod 72 rotates, it can drive the scraper 7 to move synchronously. The bottom output end of the driving motor 71 passes through the sampling tube 4, and the bottom output end of the driving motor 71 is fixedly connected to the upper end of the rotating rod 72. When the driving motor 71 is started, the scraper 7 can be driven to rotate through the rotating rod 72, and the opening and closing of the sampling port 6 can be controlled.

[0026] A pointed cone 8 is fixedly connected to the right side of the right surface of the scraper 7, and an inclined plate 9 is fixedly connected to the bottom of the left surface of the scraper 7. When the scraper 7 is rotated and opened, the pointed cone 8 can be driven to penetrate the inner wall of the hole. At this time, the motor 3 is started to drive the sampling tube 4 to rotate clockwise, so that the pointed cone 8 loosens the soil in the inner wall of the hole that has hardened due to the screwing of the drill bit 5. Then the motor 3 is started to drive the sampling tube 4 to rotate counterclockwise. At this time, the scraper 7 can scrape the soil at the inner wall of the hole, so that the soil falls onto the inclined plate 9 and slides along the inclined surface of the inclined plate 9 into the interior of the sampling tube 4 to complete the sampling, thereby avoiding the situation where the sampling tube 4 cannot enter the sampling tube 4 for sampling after entering the hole due to the soil being not loose enough.

[0027] The interior of the sampling tube 4 is sleeved with a movable plate 10, which can perform linear motion in the up and down directions inside the sampling tube 4. A movable unit is provided inside the movable plate 10, which includes a pull rod 101, which is fixedly connected to the left side of the upper surface of the movable plate 10, and the upper end of the pull rod 101 passes through the sampling tube 4. The upper end of the pull rod 101 is fixedly connected to a circular plate 102. The staff can pull the pull rod 101 and the movable plate 10 upward through the circular plate 102. The bottom surface of the movable plate 10 is fixedly connected to an elastic member 103, and the bottom end of the elastic member 103 is fixedly connected to the inner bottom surface of the sampling tube 4. When the soil enters After entering the sampling tube 4, it will accumulate on the movable plate 10, squeezing the movable plate 10 downward and squeezing the elastic member 103. After collecting enough samples, when pulling the sampling tube 4 out of the hole, the circular plate 102 can be pulled upward to drive the movable plate 10 to move upward, so that the upper surface of the movable plate 10 and the bottom surface of the sampling port 6 are at the same horizontal plane, which is convenient for taking out the samples. The collected samples will enter the space below the sampling port 6 inside the sampling tube 4 and cannot fall out of the sampling port 6. This can prevent the soil from falling out of the sampling port 6 while entering the sampling tube 4 during sampling, thereby affecting the sampling efficiency.

[0028] Reference Figure 4-Figure 5 , a U-shaped tube 11 is provided on the front side of the interior of the sampling cylinder 4. The U-shaped tube 11 can be made of transparent PVC material, and the interior of the U-shaped tube 11 can be directly observed. Liquid is stored in the U-shaped tube 11, and the liquid is a colored solution. The front end of the U-shaped tube 11 passes through the sampling cylinder 4, and a rubber plug 12 is inserted into the upper end of the front side of the U-shaped tube 11. The rubber plug 12 can seal the upper end of the front side of the U-shaped tube 11 to prevent impurities from falling into the U-shaped tube 11 when not in use. A rubber piston 13 is inserted into the upper end of the rear side of the U-shaped tube 11, and the upper surface of the rubber piston 13 is fixedly connected to a connecting rod 14. The upper end of the connecting rod 14 is fixedly connected to the bottom surface of the movable plate 10. When the movable plate 10 is moved downward When moving, the rubber piston 13 can be driven to move synchronously by the connecting rod 14. When the soil enters the sampling tube 4 and squeezes the movable plate 10, the movable plate 10 moves downward to drive the rubber piston 13 to move synchronously. At this time, the rubber piston 13 moves downward inside the U-shaped tube 11, squeezing the colored solution in the U-shaped tube 11, so that the liquid level at the front end of the U-shaped tube 11 moves upward. The staff can judge the moving distance of the movable plate 10 by observing the changes in the liquid level in the U-shaped tube 11, and then judge the sampling amount entering the sampling tube 4, to avoid the situation where the sampling tube 4 is taken out when the soil sample in the sampling tube 4 does not meet the standard.

[0029] Working principle: When collecting samples, the movable frame 2 can be pressed down and the motor 3 can be started. At the same time, the rubber plug 12 can be removed to drive the drill bit 5 to screw down into the soil. When the sampling tube 4 moves to the desired position, the motor 3 is stopped and the downward pressure is stopped. Then, the drive motor 71 is started to drive the scraper 7 to rotate to open the sampling port 6, and the sharp cone 8 is inserted into the inner wall of the hole. The motor 3 is started to drive the sampling tube 4 to rotate clockwise, so that the sharp cone 8 loosens the soil on the inner wall of the hole that has hardened due to the screwing of the drill bit 5. Then, the motor 3 is started to drive the sampling tube 4 to rotate counterclockwise, driving the scraper 7 to scrape the soil on the inner wall of the hole. , so that the sample soil enters the sampling tube 4 along the inclined surface of the inclined plate 9. As the soil enters, the movable plate 10 is squeezed, causing the movable plate 10 to move downward. As the movable plate 10 moves downward, the rubber piston 13 is driven to squeeze the colored solution in the U-shaped tube 11. The staff can judge the moving distance of the movable plate 10 by observing the changes in the liquid level in the U-shaped tube 11, and then judge the amount of sample entering the sampling tube 4. After the sampling is completed, the drive motor 71 is started to drive the scraper 7 to rotate and close the sampling port 6, and then the movable frame 2 is lifted upward to drive the sampling tube 4 to leave the hole. The operation is simple and easy.
