[0024] Example 1

[0025] like Figs. 1 to 4 As shown in the figure, this embodiment illustrates a combined adjustable rock exploration sampling device, including a base 7. The center of the base 7 is provided with an axially penetrating cylindrical hole, which is used to provide a linear movement channel for the drill rod and ensure the smooth passage of the rock core sample. It is also provided with an adjustable drive unit and a sampling unit. The adjustable drive unit is detachably mounted on the base 7, and the adjustable drive unit adjusts the sampling unit to adapt to different sampling depths.

[0026] Specifically, a level 8 is installed on one side of the foundation 7, near the front, to monitor and adjust the level of the foundation in real time, ensuring that the sampling device remains stable during operation.

[0027] In this embodiment, the adjustable drive unit includes a motor 1, a bracket 2, a smooth sleeve rod 3, an electric push rod 5, and a threaded base 6;

[0028] Two threaded bases 6 are arranged in a mirror-symmetrical manner on both sides of the top surface of the support 7. Each threaded base 6 is equipped with a telescopic electric push rod 5 above it. The outer wall of the threaded base 6 is threadedly connected to the inner wall of one end of the electric push rod 5. Two brackets 2 are arranged in a mirror-symmetrical manner on both sides of the motor 1. One end of the hollow smooth sleeve rod 3 is located below the bracket 2. The other end of the electric push rod 5 relative to the support 7 can be inserted into the smooth sleeve rod 3 to fix the motor 1 through the bracket 2. The extra stroke provided by the electric push rod 5 can be used to drill downwards, obtaining longer core samples in one go and reducing repeated operations.

[0029] Specifically, the two threaded bases 6 are symmetrical to the axis of the cylindrical hole, the motor 1 is located above the electric push rod 5 and is supported by the two side supports 2, and the smooth sleeve rod 3 below the support 2 is used to connect the top end of the electric push rod 5 to stably support the motor 1.

[0031] One end of the rotating rod 4 is connected with the output shaft of the motor 1, and the other end extends into the drill rod 13, a plurality of cylindrical insertion slots are arranged between the connecting part of the rotating rod 4 and the drill rod 13, and the cylindrical insertion slots are in communication, the cylindrical insertion slots are in ring shape and equidistantly distributed, the rotating rod 4 and the drill rod 13 are connected by inserting the cylindrical plug 15 into the cylindrical insertion slot, the drill bit 14 is arranged at the end of the drill rod 13 away from the rotating rod 4, and the length of the drill rod 13 can be replaced according to requirements to adapt to different sampling depths.

[0032] It should be noted that the cylindrical insertion slots of the rotating rod 4 and the drill rod 13 correspond to each other one by one, and the length of the one-time drilling sampling and the size of the sample diameter can be adjusted by adjusting the maximum retractable length of the electric push rod 5 and by installing drill rods 13 with different lengths and diameters.

[0033] The support part includes a threaded sleeve 9, a support foot rod 10, a threaded rod 11 and a sharp end 12.

[0034] A plurality of threaded sleeves 9 are arranged at the corner positions on one side of the bearing platform 7, each threaded sleeve 9 is connected with a corresponding support foot rod 10, the end of the support foot rod 10 is provided with a sharp end 12 in the shape of a cone, which can be stably inserted into the ground to fix the entire device.

[0035] Specifically, each threaded sleeve 9 is located at a position inward from the corner of the bearing platform 7 by a certain distance, i.e. adjacent to the corner, if the threaded sleeve 9 is directly located at the outermost edge of the bearing platform 7, i.e. immediately adjacent to the corner, when bearing external load, stress may be concentrated at these positions, which may increase the risk of fracture or damage of the middle structure of the bearing platform 7, by arranging the threaded sleeve at a position 20-50 mm inward from the corner, the load can be effectively dispersed, the local stress concentration can be reduced, and the durability and reliability of the entire structure can be improved, the upper part of the support foot rod 10 is a threaded rod 11, the threaded rod 11 is connected with the threaded sleeve 9 through threads, so as to adjust the height of the support foot rod 10 by rotating, so as to keep the bearing platform 7 horizontal, and the sharp end 12 can be inserted into the target area to fix the position, and the bearing platform 7 is kept horizontal by adjusting the rotation amount of the threaded rod 11 relative to the threaded sleeve 9 and observing the level 8.

[0036] The target area can be rock or soil on the ground.

[0037] In the specific implementation, before sampling, the instrument is assembled first, four threaded rods 11 are distributed and screwed into four threaded sleeves 9, the threaded rods 11 are fixed below the bearing platform 7, the bottoms of two groups of electric push rods 5 are fixed on the bearing platform 7 above the left and right symmetrical positions through threaded bases 6, the motor 1 is installed, the rotating rod 4 of the motor 1 is extended below the bearing platform through the center of the bearing platform 7, then the direction of the motor 1 is adjusted, the brackets 2 connected on the left and right sides are aligned with the two groups of electric push rods 5 respectively, the tops of the electric push rods 5 are inserted into the smooth sleeve rods 3 at the bottoms of the brackets 2, so as to fix the position of the motor. The rotating rod 4 of the motor 1 is inserted into the top of the drill rod 13, and the drill rod 13 is connected at the bottom of the rotating rod 4 through the plug 15, so that the drill rod 13 can rotate with the rotating rod 4 when the motor works.

[0038] After the instrument is assembled, the sampling work is carried out, the instrument is placed at the specified sampling site, the sharp ends 12 at the bottoms of the supporting foot rods 10 are inserted into the ground to play a position fixing role, then the amount of rotation is adjusted, and the level 8 is observed to keep the bearing platform 7 horizontal. The motor 1 starts to work, and at the same time, the brackets 2 on the left and right sides of the motor 1 are pushed downward, the electric push rods 5 are driven to shrink downward by the brackets 2, and then the drill rod 13 is indirectly pushed to drill into the ground to drill rock samples. In theory, the length of one-time drilling sampling and the size of the sample diameter can be adjusted by adjusting the maximum length of the electric push rod 5 that can be lifted and shrunk and the length and diameter of the drill rod 13.
