Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0024] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0025] Such as Figures 1-4As shown in the figure, the embodiment of the present utility model provides an oil distribution sampler for oil exploitation, including a U-shaped frame 1. Two cylinders 2 are embedded at the top of the inner wall of the U-shaped frame 1. The bottom end of the output shaft of the cylinder 2 is fixedly installed with a rectangular plate 3. The rectangular plate 3 is movably arranged between the left inner wall and the right inner wall of the U-shaped frame 1. A first sampling cylinder 4 is arranged below the rectangular plate 3, and a second sampling cylinder 5 is arranged below the rectangular plate 3.

[0026] In one embodiment, two mounting holes 8 are opened at the top of the inner wall of the U-shaped frame 1. The inner walls of the two mounting holes 8 are fixedly connected to the outer sides of the cylinders 2. Through the opened mounting holes 8, it is convenient to fix the cylinders 2 on the top of the inner wall of the U-shaped frame 1.

[0027] In one embodiment, guide blocks 7 are fixedly installed on both the left side and the right side of the rectangular plate 3. Guide holes 6 are opened on both the left inner wall and the right inner wall of the U-shaped frame 1. The outer sides of the guide blocks 7 are in movable contact with the inner walls of the guide holes 6. Through the cooperation of the provided guide holes 6 and the guide blocks 7, the movement of the rectangular plate 3 is guided.

[0028] In one embodiment, a first transmission shaft 9 is fixedly installed on the upper surface of the first sampling cylinder 4, and a second transmission shaft 10 is fixedly installed on the upper surface of the second sampling cylinder 5. The first transmission shaft 9 and the second transmission shaft 10 are both rotatably installed inside the rectangular plate 3 through bearings. The tops of the first transmission shaft 9 and the second transmission shaft 10 both extend above the rectangular plate 3. First transmission wheels 16 are fixedly sleeved on the outer sides of the first transmission shaft 9 and the second transmission shaft 10. A motor 11 is fixedly installed on the upper surface of the rectangular plate 3. The bottom end of the output shaft of the motor 11 is fixedly installed with a third rotating shaft 15. The third rotating shaft 15 is rotatably installed inside the rectangular plate 3 through a bearing. A second transmission wheel 19 is fixedly sleeved on the outer side of the third rotating shaft 15. A transmission belt 18 is connected in transmission between the second transmission wheel 19 and the two first transmission wheels 16. By starting the motor 11 to drive the third rotating shaft 15 to rotate, the third rotating shaft 15 drives the transmission belt 18 to move, the transmission belt 18 drives the first transmission shaft 9 and the second transmission shaft 10 to rotate, the first transmission shaft 9 drives the first sampling cylinder 4 to rotate, and the second transmission shaft 10 drives the second sampling cylinder 5 to rotate, so that it is convenient to separately sample soils at different depths simultaneously.

[0029] In one embodiment, a push plate 12 is movably provided inside the first sampling tube 4 and the second sampling tube 5, and a connecting rod 13 is fixedly installed on the upper surface of the push plate 12. The top ends of the two connecting rods 13 extend to above the first transmission shaft 9 and the second transmission shaft 10, and a cross bar 14 is fixedly installed on the top ends of the two connecting rods 13. The outer sides of the two push plates 12 are in movably contact with the inner walls of the first sampling tube 4 and the second sampling tube 5 respectively. After the sampling is completed, the cross bar 14 is pushed downward to drive the two connecting rods 13 to move downward, and the two connecting rods 13 drive the two push plates 12 to move downward. Under the setting of the two push plates 12, the soil inside the first sampling tube 4 and the second sampling tube 5 is pushed out.

[0030] In one embodiment, a through hole 17 is provided on the upper surface of the first transmission shaft 9 and the second transmission shaft 10, and the inner wall of the through hole 17 is in movable contact with the outer side of the connecting rod 13. Through the through hole 17, the two connecting rods 13 can move inside the first transmission shaft 9 and the second transmission shaft 10 respectively.

[0031] When the utility model is working, the sampler is placed at the position where sampling is to be performed, and power is provided to the cylinder 2 and the motor 11 through an external power supply, and the two cylinders 2 are started, so that the two cylinders 2 push the rectangular plate 3 to move downward, and the rectangular plate 3 drives the two guide blocks 7 to move downward along the guide hole 6, and the downward movement of the rectangular plate 3 also drives the first sampling tube 4 and the second sampling tube 5 to move downward, and when the lower surface of the first sampling tube 4 contacts the ground, the motor 11 is started, so that the motor 11 drives the third rotating shaft 15 to rotate, and the rotation of the third rotating shaft 15 drives the second The transmission wheel 19 rotates, and the second transmission wheel 19 drives the transmission belt 18 to move. Since the two first transmission wheels 16 and the second transmission wheel 19 are connected by the transmission belt 18, the two first transmission wheels 16 rotate while the transmission belt 18 moves. The two first transmission wheels 16 respectively drive the first transmission shaft 9 and the second transmission shaft 10 to rotate. At the same time, the first transmission shaft 9 drives the first sampling barrel 4 to rotate, and the second transmission shaft 10 drives the second sampling barrel 5 to rotate. The first sampling barrel 4 and the second sampling barrel 5 rotate and move downward at the same time to sample the soil.

[0032] During the sampling process, when the soil enters the interiors of the first sampling cylinder 4 and the second sampling cylinder 5, it pushes the push plate 12 to move upward. At the same time, the push plate 12 also drives the connecting rod 13 to move upward. The two connecting rods 13 push the cross bar 14 to move upward. Since the lengths of the first sampling cylinder 4 and the second sampling cylinder 5 are different, it is convenient to separately sample soils at different depths simultaneously. After the sampling is completed, reverse-start the two cylinders 2. The cylinders 2 drive the rectangular plate 3 to move upward. The rectangular plate 3 drives the first sampling cylinder 4 and the second sampling cylinder 5 to move upward until the first sampling cylinder 4 and the second sampling cylinder 5 are completely removed from the soil interior. Subsequently, place the sample placement boxes respectively below the first sampling cylinder 4 and the second sampling cylinder 5, and push the cross bar 14 downward, so that the cross bar 14 drives the two connecting rods 13 to move downward. The two connecting rods 13 push the two push plates 12 to move downward. Under the action of the push plates 12, the samples inside the first sampling cylinder 4 and the second sampling cylinder 5 are pushed out, making it convenient to push out the collected soil samples and improving the portability during use.

Any person skilled in the art in the technical field disclosed by the present utility model can easily think of various changes or substitutions within the technical scope disclosed by the present utility model, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
