[0032] The present invention will now be described in detail with reference to the embodiments, but the present invention is not limited to these embodiments.

[0033] This utility model embodiment provides a sampling device for engineering exploration, such as... Figures 1 to 2 As shown, the device includes:

[0034] The sampling cylinder 1 has a through hole at the top and a through sampling port 9 on its cylinder wall;

[0035] The screw 4 is fitted into the through hole of the sampling cylinder 1 and connected to the sampling cylinder 1. The screw 4 can rotate inside the sampling cylinder 1.

[0036] A scraper 10 is placed on the sampling port 9, and its bottom end is rotatably connected to the lower edge of the sampling port 9.

[0037] The transmission structure is threadedly connected to the screw 4 and rotatably connected to the scraper 10; it can drive the scraper 10 to rotate around the lower edge of the sampling port 9 when the screw 4 rotates.

[0038] In this embodiment, the screw 4 and the sampling cylinder 1 are coaxially arranged.

[0039] Specifically, the size of the scraper 10 can be matched with the sampling port 9 to close the sampling port 9.

[0040] Specifically, the scraper 10 can rotate in the forward direction or in the reverse direction. When the sampling cylinder 1 is placed in the exploration hole and sampling is required, the transmission structure drives the scraper 10 to rotate in the forward direction, and the top of the scraper 10 moves away from the sampling cylinder 1, so that the sampling port 9 opens to facilitate sampling. After sampling is completed, the transmission structure drives the scraper 10 to rotate in the reverse direction, and the top of the scraper 10 moves towards the sampling cylinder 1, so that the sampling port 9 closes to facilitate the removal of the sampling cylinder 1 from the exploration hole.

[0041] Specifically, such as Figure 3 As shown, the transmission structure may include:

[0042] The lifting sleeve 5 is sleeved on the screw 4 and threadedly connected to the screw 4, and can move along the axial direction of the screw 4 when the screw 4 rotates;

[0043] The connecting rod 7 is rotatably connected at one end to the lifting sleeve 5 and at the other end to the scraper 10. When the lifting sleeve 5 moves, it can drive the scraper 10 to rotate around the lower edge of the sampling port 9.

[0044] In this embodiment, the connecting rod 7 is rotatably connected to the lifting sleeve 5 via the first hinge seat 6, and rotatably connected to the scraper 10 via the second hinge seat 8.

[0045] Specifically, the lifting sleeve 5 can be located above or below the scraper 10, both of which can control the opening and closing of the scraper 10.

[0046] Specifically, there can be multiple sampling ports 9, which are evenly distributed around the wall of the sampling cylinder 1.

[0047] Correspondingly, there can be multiple scrapers 10 and connecting rods 7. Multiple scrapers 10 correspond one-to-one with multiple sampling ports 9, and multiple connecting rods 7 correspond one-to-one with multiple scrapers 10. Multiple connecting rods 7 are evenly distributed around the edge of the lifting sleeve 5.

[0048] In this embodiment, there are four sampling ports 9, four scrapers 10, and four connecting rods 7.

[0049] Specifically, the bottom end of the screw 4 can be rotatably connected to the bottom of the sampling cylinder 1 to restrict the screw 4 from moving along its axial direction. Alternatively, a component for rotatably connecting with the screw 4 can be provided inside the sampling cylinder 1.

[0050] In this embodiment, the device may further include:

[0051] The base frame 3 is a hollow structure and is set inside the sampling cylinder 1, with its edge fixedly connected to the cylinder wall; the bottom end of the screw 4 is rotatably connected to the base frame 3.

[0052] By setting the base frame 3, it is possible to ensure that the screw 4 can rotate around its axis while restricting its movement along its axis. In this way, when the screw 4 rotates, the lifting sleeve 5 can move along the axis of the screw 4 to drive the scraper 10 to rotate.

[0053] Specifically, by setting the base frame 3 as a hollow structure, the soil entering the sampling tube 1 can pass smoothly through the hollow structure of the base frame 3 and fall to the bottom of the inner cavity of the sampling tube 1, thereby avoiding the accumulation of soil on the base frame 3.

[0054] In this embodiment, the base frame 3 is cross-shaped, and the four ends of the base frame 3 are fixedly connected to the wall of the sampling tube 1. Soil falls into the bottom of the inner cavity of the sampling tube 1 through the gap between the base frame 3 and the wall.

[0055] Specifically, the sampling cylinder 1 has an opening at the bottom; the device may also include:

[0056] Cylinder cover 2, placed over the opening to seal it.

[0057] Specifically, the cap 2 is threadedly connected to the edge of the opening of the sampling cylinder 1.

[0058] Specifically, the device may also include:

[0059] The insertion tube is sleeved on the outer wall of the screw 4 and connected to the top of the sampling tube 1; the top end of the screw 4 extends out from the insertion tube.

[0060] By setting up the insertion tube, the sampling personnel can hold the insertion tube and move it to place and retrieve the sampling tube 1, which facilitates the operation of the sampling personnel; at the same time, the insertion tube is sleeved on the screw 4, which can also protect the screw 4.

[0061] Specifically, the insertion tube has an upper section 12 and an lower section 11 connected to each other, with the outer diameter of the upper section 12 being larger than the outer diameter of the lower section 11. The larger outer diameter of the upper section 12 makes it easier for the sampling personnel to hold.

[0062] Specifically, the device may also include:

[0063] A handle 13 is attached to the top of the screw 4. By setting the handle 13, the sampling personnel can rotate the screw 4 by turning the handle 13, which facilitates the operation of the sampling personnel.

[0064] The following describes how to use this embodiment:

[0065] (1) Hold the insertion tube and insert the sampling tube 1 into the exploration hole;

[0066] (2) Hold the handle 13 and rotate the screw 4 in the forward direction to make the lifting sleeve 5 move downward; the lifting sleeve 5 drives the connecting rod 7, and the connecting rod 7 pushes the scraper 10 to rotate in the forward direction around the lower edge of the sampling port 9, so that the sampling port 9 opens.

[0067] (3) Hold the insertion tube and pull it upwards. The scraper 10 scrapes the soil on the inner wall of the exploration hole into the sampling tube 1.

[0068] (4) Hold the handle 13 and rotate the screw 4 in the opposite direction to make the lifting sleeve 5 move upward; the lifting sleeve 5 drives the connecting rod 7, and the connecting rod 7 pulls the scraper 10 to rotate in the opposite direction around the lower edge of the sampling port 9, so that the sampling port 9 is closed.

[0069] (5) Hold the insertion tube and pull the sampling tube 1 out of the exploration hole;

[0070] (6) Open the tube cover 2 and pour out the soil in the sampling tube 1 to complete the sampling.

[0071] This invention uses a rotating screw 4 to drive a transmission structure, which in turn drives a scraper 10 to rotate around the lower edge of the sampling port 9, thus pushing the scraper 10 outward or pulling it inward. This invention places the sampling cylinder 1 inside the exploration hole. After the scraper 10 is pushed outward, soil is scraped for sampling. After the scraper 10 is pulled inward, the sampling cylinder 1 is removed from the exploration hole. This improves the convenience and efficiency of soil sampling within the exploration hole.

[0072] The above description is merely a few embodiments of this application and is not intended to limit this application in any way. Although this application discloses preferred embodiments as described above, it is not intended to limit this application. Any changes or modifications made by those skilled in the art without departing from the scope of the technical solution of this application using the disclosed technical content are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
