Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0026] The utility model discloses a drilling rig drill barrel capable of complete layered sampling, which is mainly used in the scene of geological sampling.

[0027] Reference Figure 1 and Figure 2 A drilling rig drill barrel capable of complete stratified sampling comprises: a mounting frame 1, a hydraulic cylinder 2 is arranged on the top of the mounting frame 1, a shell 3 is fixedly connected to the bottom of the hydraulic cylinder 2, connecting plates 6 are fixedly connected to both sides of the shell 3, a groove 7 is provided inside the mounting frame 1, one side of the connecting plate 6 is slidably connected to the inside of the groove 7, a fixing component is arranged inside the mounting frame 1, a motor 13 is arranged inside the shell 3, a sleeve 14 is rotatably connected to the bottom of the shell 3, and a sampling component is arranged at the bottom of the sleeve 14.

[0028] In the above technical scheme, considering the problem that the soil is easy to fall during extraction and cannot meet the use requirements, in order to solve such problems, the specific operations are as follows: by setting a sampling component, the soil can be collected through the sampling component, and an anti-drop mechanism is provided in the sampling component to prevent the collected soil from falling. At the same time, the sampling component adopts a splicing type, which is convenient for disassembly and is conducive to taking out the collected soil intact. By setting a fixing component, the mounting frame 1 can be fixed to avoid shaking of the device during the sampling process, which affects the collection of the soil.

[0029] Reference Figures 3 to 7 In a preferred embodiment, the sampling assembly includes a mounting block 15, which is slidably connected to the inside of the sleeve 14, and the first drill tube 4 and the second drill tube 11 are respectively arranged at the bottom of the mounting block 15, and the drill bit 5 is threadedly connected to the bottom of the first drill tube 4 and the second drill tube 11, and a bolt 17 is arranged between the sleeve 14 and the mounting block 15, and a positioning groove 19 is opened on one side of the first drill tube 4, and a positioning block 18 is fixedly connected to one side of the second drill tube 11, and the positioning block 18 and the positioning groove 19 are both arranged in a T-shape, and a fixing plate 20 is fixedly connected to the inside of the drill bit 5 at an equal distance, and a baffle 21 is rotatably connected between one side of the fixing plate 20, and a limiting block 16 is arranged on one side of the fixing plate 20 and at the bottom of the baffle 21;

[0030] In the above technical scheme, the problem that the collected soil is easy to fall is taken into consideration. In order to solve such problem, the specific operation is as follows: the soil is collected into the drill barrel through the through hole at the bottom of the drill bit 5. At this time, the baffle 21 is in an open state under the push of the soil. When the soil collection is completed, the soil in the drill barrel is pressed against the baffle 21 under the action of gravity. The baffle 21 can be supported by the limit block 16. At this time, the baffle 21 is in a closed state, which can prevent the soil from falling. Then the bolt 17 is removed, so that the mounting block 15, the first drill barrel 4, the second drill barrel 11 and the drill bit 5 are removed and placed horizontally. Then the mounting block 15 and the drill bit 5 are removed by threading, and then the second drill barrel 11 is placed on it, and the second drill barrel 11 is pushed to slide to separate it from the first drill barrel 4. In this way, the soil can be taken out completely and the sampling work is completed. A complete soil sample can provide more accurate test results, which is conducive to accurate evaluation and decision-making of scientific research and engineering projects.

[0032] In the above technical solution, the problem that the device may shake during the sampling process is taken into consideration. In order to solve such a problem, the specific operation is as follows: by pressing the pressing block 9 with the hand, the positioning rod 12 is driven to come out of the through hole 10, so that the tip of the bottom of the sliding rod enters the ground, and then the device is fixed to the ground, which can ensure that the device remains stable during the sampling process and avoid affecting the accuracy and integrity of the sampling due to movement or shaking.

[0033] Working principle: When in use, first place the device in the sampling area, press the pressing block 9 by hand to drive the positioning rod 12 out of the through hole 10, so that the tip of the bottom of the sliding rod enters the ground, and then fix the device on the ground, and start the hydraulic cylinder 2 and the motor 13 at the same time, drive the drill bit 5 close to the ground and rotate quickly to collect and sample the soil. At this time, the baffle 21 is in an open state under the push of the soil. When the soil collection is completed, the soil in the drill tube is pressed against the baffle 21 under the action of gravity, and the baffle 21 can be closed by using the limit block 16 Support is provided, at this time the baffle 21 is in a closed state, which can prevent the soil from falling down, and then the bolts 17 are removed, so that the mounting block 15, the first drill tube 4, the second drill tube 11 and the drill bit 5 are removed and placed horizontally, and then the mounting block 15 and the drill bit 5 are threadedly removed, and then the second drill tube 11 is placed on top, and the second drill tube 11 is pushed to slide to separate it from the first drill tube 4, so that the soil can be taken out completely, and the soil sampling work is completed, the operation is simple, convenient and fast, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
