Description

Technical Field

[0001] The present invention relates to the technical field of soil sampling, and in particular to a soil environment detection sample sampling device. Background Art

[0002] In order to obtain soil samples for testing, it is necessary to drill into the stratum, and after drilling to the designated location, samples are taken through a sampling tube;

[0003] The existing drilling device is supported by a stable frame. The drill rod is driven by hydraulic telescopic drive and motor rotation drive to drive the drill rod and drill barrel downward for drilling. After drilling, another set of hydraulic drive and rotation drive are continued to make the sampling barrel downward for sampling.

[0004] However, when the sampling tube follows the drill tube downward, the following problems arise:

[0005] 1. When the sampling tube moves downward with the drill tube, it is exposed to the outside, and soil can easily enter the inside of the sampling tube, resulting in a large error in the test results;

[0006] Second, after the soil is taken from the sampling tube, it is necessary to squeeze it out from the sampling tube manually, which increases the labor force;

[0007] In response to the above problems, we propose a sample sampling device for soil environment testing. Summary of the Invention

[0008] In response to the above problems, the present invention provides a sample sampling device for soil environment testing, which surrounds the blocking drill barrel with four blocking drill plates to prevent soil at different positions from entering the sampling barrel when the drill barrel moves downward. At the same time, the present invention provides a bidirectional screw, a bracket 1 threadedly connected to the bidirectional screw, and a bracket 2 slidingly connected to the bidirectional screw in a key-strip manner, so that the sampling barrel can be rotated and moved downward under the drive of a driving motor, thereby avoiding waste of resources. The blocking drill plates are formed into a cone shape to prevent soil from entering the sampling barrel during the downward movement of the sampling barrel. Finally, a top plate is provided on the bidirectional screw to effectively squeeze out the sampled soil in the sampling barrel, thereby avoiding the inconvenience of manual soil collection in the later stage.

[0009] The present invention provides a sample sampling device for soil environment detection, which includes a stabilizing frame and a drill rod. The drill rod movably passes through the stabilizing frame. A drill barrel is fixedly connected to the lower end surface of the drill rod. The inner cavity of the drill barrel is a regular quadrilateral. A bidirectional screw is provided in the drill barrel. The bidirectional screw is connected to the drill barrel, and a top plate is coaxially fixed on the bidirectional screw.

[0010] The drill barrel is also provided with a blocking mechanism, which is threadedly connected to the bidirectional screw, and the blocking mechanism includes a telescopic bracket mechanism and a blocking drill plate. The telescopic bracket mechanism is threadedly connected to the bidirectional screw, and the blocking drill plate is rotatably connected to the lower end wall of the telescopic bracket mechanism. A pushing frame is fixedly connected to the inner wall of the drill barrel. When the blocking drill plate moves into the pushing frame, the pushing frame pushes the blocking drill plate to rotate; the telescopic bracket mechanism includes a moving frame one and a moving frame two. The moving frame one is threadedly connected to the bidirectional screw, and the moving frame two is spring-loaded and slidably provided on the moving frame one, and the blocking drill plate is rotatably connected to the lower end surface of the moving frame two. The blocking drill plate is provided with four, which are respectively rotatably provided on the four end surfaces below the moving frame two. When the blocking drill plate slides into the pushing frame, the pushing frame pushes the four blocking drill plates to rotate, and the four blocking drill plates form a pyramid shape to block the inner cavity of the drill barrel.

[0011] A sampling mechanism is also provided in the drill barrel, which is threadedly connected to the bidirectional screw and is slidably arranged inside the sealing mechanism. The sampling mechanism includes bracket one, bracket two, and a sampling barrel. The lower end of the bidirectional screw surface is a smooth and non-threaded structure. Bracket two is connected to the smooth and non-threaded structure of the bidirectional screw in a key-like manner for sliding up and down, and is also slidably connected to the telescopic bracket mechanism. Bracket two is rotatably arranged on the lower end surface of bracket one, and bracket two is connected to the bidirectional screw in a key-like manner for sliding up and down. The sampling barrel is fixed to the lower end surface of bracket two, and the top plate is arranged in the sampling barrel.

[0012] Beneficial effects of the present invention: The present invention provides a soil environment detection sampling device:

[0013] First, the present invention is provided with a bidirectional screw, a bracket 1 threadedly connected to the bidirectional screw, and a bracket 2 key-strip slidingly connected to the bidirectional screw, so that the sampling tube can be rotated and moved downward under the drive of a driving motor, thereby avoiding waste of resources;

[0014] Second, the four blocking drill plates surround the blocking drill tube to prevent soil from entering the sampling tube when the drill tube moves downward, and the blocking drill plates are formed into a pyramid shape, which facilitates drilling when the drill tube moves downward;

[0015] 3. A top plate is set on the bidirectional screw. When the sealing drill plate is formed into a cone and the sampling tube continues to move upward, the top plate enters the sampling tube, effectively squeezing out the sampling soil in the sampling tube, avoiding the inconvenience of manual soil collection at a later time.

[0031] according to Figures 1-11 The sample sampling device for soil environment detection shown in the figure includes a stabilizing frame 1 and a drill rod 2. The drill rod 2 moves through the stabilizing frame 1. The lower end of the stabilizing frame 1 is connected to a locking wheel, which facilitates the movement and locking of the device. A drill barrel 3 is fixedly connected to the lower end surface of the drill rod 2. The inner cavity of the drill barrel 3 is a regular quadrilateral, and the end surface of the drill barrel 3 away from the drill rod 2 is serrated, which is convenient for drilling the stratum. A drive motor 19 is fixedly connected to the top of the inner wall of the drill barrel 3, and the output end of the drive motor 19 is fixedly connected to a bidirectional screw 4 arranged in the drill barrel 3. A coaxial fixing sleeve is provided on the bidirectional screw 4, and a coaxial fixing sleeve is provided on the bidirectional screw 4.

[0032] The drill tube 3 is also provided with a blocking mechanism 6, which includes a telescopic support mechanism 7 and a blocking drill plate 8. The telescopic support mechanism 7 is threadedly connected to the bidirectional screw 4, and the blocking drill plate 8 is rotatably connected to the lower end wall of the telescopic support mechanism 7. A pushing frame 9 is fixed to the inner wall of the drill tube 3. The telescopic support mechanism 7 includes a moving frame 14 and a moving frame 2 15. The moving frame 14 is threadedly connected to the bidirectional screw 4, and the moving frame 2 15 is spring-loaded and slidably arranged on the moving frame 14. The blocking drill plate 8 is rotatably connected to the lower end surface of the moving frame 2 15. The blocking drill plate 8 is provided with four, which are respectively rotated on the four end surfaces below the moving frame 2 15. When the blocking drill plate 8 slides into the pushing frame 9, the pushing frame 9 pushes the four blocking drill plates 8 to rotate. The four blocking drill plates 8 are surrounded by a pyramid shape to block the inner cavity of the drill tube 3. The four blocking drill plates 8 are surrounded by a pyramid shape, which is also convenient for drilling the stratum.

[0033] The specific manner in which the spring-type sliding of the movable frame 2 15 is arranged on the movable frame 14 is as follows: a vertical rod 16 is fixedly connected to the lower end surface of the movable frame 14, a vertical rod hole 17 is provided on the upper end surface of the movable frame 2 15, the vertical rod 16 extends into the vertical rod hole 17, a spring 18 is provided in the vertical rod hole 17, and the spring 18 is arranged at the lower end of the vertical rod 16.

[0034] A sampling mechanism 5 is also provided in the drill tube 3, and the sampling mechanism 5 includes a bracket 10, a bracket 2 11, and a sampling barrel 12. The bracket 10 is threadedly connected to the bidirectional screw 4 and is slidingly connected to the movable frame 14. The movable frame 14 is fixed with a guide rail for the bracket 10 to move up and down. The lower half of the guide rail is in contact with the movable frame 2 15. The bracket 2 11 is rotatably arranged on the lower end surface of the bracket 10. The lower part of the surface of the bidirectional screw 11 is a smooth and non-threaded structure. The bracket 2 11 and the bidirectional screw 4 are smoothly and non-threaded and are connected to each other in a key-like manner for sliding up and down. The sampling barrel 12 is fixed to the lower end surface of the bracket 2 11. When the drive motor 19 does not start sampling, the top plate 13 is arranged at the lower end of the sampling barrel 12. When sampling, the top plate 13 moves to above the sampling barrel 12.

[0035] Principle of the present invention:

[0036] When in use, the stabilizing frame 1 is pushed to the designated position, the locking wheel is locked to prevent the stabilizing frame 1 from moving, and the hydraulic telescopic drive and the motor rotation drive drive the drill rod 2 and the drill barrel 3 to move downward to drill the formation. After drilling to the designated position, the hydraulic telescopic drive and the motor rotation drive stop running;

[0037] The driving motor 19 is started, driving the bidirectional screw 4 to rotate, driving the mobile frame 14 and the vertical rod 16 to move upward. After the vertical rod 16 moves a certain distance, the vertical rod 16 drives the mobile frame 2 15 to move upward, driving the blocking drill plate 8 to move upward. When the four blocking drill plates 8 move upward, they leave the pushing frame 9. The four blocking drill plates 8 are in a loose state and rotate under the action of gravity, leaking out of the inner cavity of the drill tube 3. When the bidirectional screw 4 rotates, it also drives the bracket 10 to move downward. Since the bidirectional screw 4 is connected to the bracket 2 11 in a key-strip sliding manner, when the bidirectional screw 4 rotates, it drives the bracket 2 11 to rotate, and the bracket 2 11 is rotationally connected to the bracket 10. Therefore, the bracket 2 11 is rotated and moved downward, thereby driving the sampling barrel 12 to rotate and move downward. The sampling barrel 12 passes through the space leaked by the four blocking drill plates 8 to perform rotational sampling of the soil.

[0038] After sampling, the driving motor 19 starts to reverse, driving the bidirectional screw 4 to rotate in the opposite direction, driving the sampling tube 12 to rotate and move upward, and the sampling tube 12 passes through the space leaked by the four blocking drill plates 8 and enters the internal cavity of the drill tube 3, and continues to rotate and move upward. When the sampling tube 12 continues to move upward, the top plate 13 enters the sampling tube 12, squeezing the sampled soil in the sampling tube 12 out of the sampling tube 12 and falling into the upper space blocked by the four blocking drill plates 8 (when the bidirectional screw 4 rotates, the movable frame 14 moves downward, under the action of gravity and the spring 18 Under the extrusion pressure, the movable frame 15 and the blocking drill plate 8 move downward, the blocking drill plate 8 extends into the pushing frame 9, and the four blocking drill plates 8 are closed. After closing, the movable frame 14 continues to move downward, and the movable frame 2 15 stops moving downward. The extrusion force of the spring 18 becomes larger until the movable frame 14 and the movable frame 2 15 are fitted together, so that the four blocking drill plates 8 are tightly attached. When the movable frame 14 continues to move downward and the movable frame 2 15 does not move downward, the top plate 13 enters the sampling tube 12, and the sampled soil in the sampling tube 12 is squeezed and falls onto the surface of the four blocking drill plates 8).

[0039] After sampling is completed, the hydraulic telescopic drive and the motor rotation drive drive the drill rod 2 and the drill barrel 3 to move up and reset. After resetting, a collection box is placed at the lower end of the drill barrel 3, and the drive motor 19 starts to rotate forward. The sealing drill plate 8 is no longer sealed, and the sampled soil falls into the collection box and is placed.

[0040] Although the present invention has been disclosed above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the authorization requirements.
