[0002] In exploration design, it is necessary to understand the soil conditions. Among them, the drilling equipment is the core equipment in the exploration, mainly used to drill holes in the soil and obtain soil samples. Its main body includes components such as drive device and auger bit. Different drilling tools can be selected according to different strata.

[0003] Existing small drilling devices include a lifting assembly and a drive assembly. The auger head installed on the outside of the drive assembly can be used to drill through soil layers. The existing auger heads are mostly connected by threads. The auger head can be extended and replaced by the cooperation of the upper and lower threaded sleeves and the threaded head. However, the threaded connection method has some inconveniences. For example, when connecting the upper and lower auger blades, it is necessary to ensure that the threaded heads are accurately aligned to prevent thread misalignment. Moreover, the threaded connection requires rotating the drill rod a lot during use, and the splicing time is long when extending the drill rod, which is especially obvious when using multiple drill rod sections. It is also more troublesome to install and disassemble.

[0004] In view of this, we propose a drilling device for exploration and design. Utility Model Content

[0008] A plug rod is slidably connected to the inner wall of the connecting shaft, and a baffle is fixedly installed on the outer surface of the plug rod.

[0009] In the above technical solution, further, the outer surface of the connecting shaft is slidably connected to the interior of both the positioning ring and the moving ring, and the outer surface of the positioning rod is slidably connected to the inner wall of the positioning cylinder.

[0010] In the above technical solution, further, the inner wall of the positioning cylinder is provided with a sliding groove and a positioning groove, the sliding groove and the positioning groove are interconnected, and the outer surface of the positioning block is slidably connected to the inner wall of the sliding groove and the positioning groove.

[0011] In the above technical solution, the outer surface of the insertion rod is slidably connected to the inner wall of the positioning groove, the outer surface of the insertion rod is in contact with the outer surface of the positioning block, and the adjacent outer surfaces of the insertion rod and the positioning block are chamfered.

[0012] In the above technical solution, further, multiple sets of insertion holes are opened inside the connecting shaft, the insertion rod moves linearly inside the insertion hole, and the baffle is located between the positioning cylinder and the insertion hole.

[0013] In the above technical solution, the inner wall of the moving ring contacts one end of the insertion rod, the outer surfaces of the moving ring and the insertion rod that are in contact are both chamfered, and the baffle contacts the positioning cylinder when the moving ring contacts one end of the insertion rod.

[0014] In the above technical solution, the upper and lower connecting shafts 2 and the spiral blades are connected by connecting shaft 1 and connecting shaft 2, and one end of each connecting shaft 2 in the same group is provided with connecting shaft 1.

[0015] The beneficial effects of this utility model are:

[0016] 1. This drilling device for exploration and design, through the cooperation between the positioning cylinder, positioning rod, and insertion rod, connects connecting shaft one and connecting shaft two through the positioning cylinder and positioning rod. At this time, connecting shaft one and connecting shaft two are aligned. Rotating the positioning rod causes the positioning block to limit the position of the positioning rod. Then, rotating the moving ring causes the moving ring to press against one end of the insertion rod. At this time, the insertion rod enters one side of the positioning block, which can limit the positioning block and positioning rod. At this time, the whole is fixed, which is convenient for installation. There is no need to repeatedly connect and rotate the drill rod to connect. It realizes the quick connection and disassembly of the drill rod in the drilling device, which is convenient for the installation of multiple sets of drill rods in depth sampling.

[0017] 2. The drilling device used for this exploration and design, by setting baffles and other components, with the baffles set on the upper and lower outer surfaces of the insertion rod, can position the insertion rod. At this time, the insertion rod will not lose contact between the insertion hole and the positioning cylinder, thus ensuring the stability of the insertion rod when it is fixed.

[0026] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0027] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0028] Example 1: This example provides a drilling device for exploration and design, including a support 1, a drive assembly 2 is installed on the outside of the support 1, a set of output ends of the drive assembly 2 are fixedly installed with a rotating disk 3, a connecting shaft 4 is fixedly installed on the lower surface of the rotating disk 3, and a positioning cylinder 5 is fixedly installed on the inner wall of the connecting shaft 4.

[0029] One end of connecting shaft 1 4 is slidably connected to connecting shaft 2 6. One end of connecting shaft 2 6 is fixedly installed with a spiral blade 7. A positioning rod 8 is fixedly installed on the inner wall of connecting shaft 2 6. A positioning block 9 is fixedly installed on the outer surface of positioning rod 8. A positioning ring 10 is fixedly installed on the outer surface of connecting shaft 2 6. A moving ring 11 is threadedly connected to the outer surface of positioning ring 10.

[0030] A plug rod 12 is slidably connected to the inner wall of the connecting shaft 4, and a baffle 13 is fixedly installed on the outer surface of the plug rod 12.

[0031] Among them, the drive assembly 2 mainly consists of a motor and a threaded rod responsible for up and down movement. The threaded rod is connected to a mounting bracket by an external thread. Another set of rotary motors is installed outside the mounting bracket. Preferably, a gasoline engine or a diesel engine can also be selected as the drive device outside the mounting bracket. The rotating disk 3 is connected to the output end of the rotary motor and rotates. When the spiral blade 7 is installed, it can drive the spiral blade 7 to rotate for drilling.

[0032] When connecting shaft 4 and connecting shaft 6, the positioning rod 8 is inserted into the positioning cylinder 5, and the positioning block 9 moves inside the positioning cylinder 5. When the positioning block 9 reaches the top position, the positioning rod 8 and connecting shaft 6 are rotated. At this time, the up and down movement and one set of circumferential rotation directions of connecting shaft 6 are limited. Then, the moving ring 11 is rotated to press against the insertion rod 12. At this time, the insertion rod 12 enters one side of the positioning block 9. The insertion rod 12 can limit the other circumferential rotation direction of the positioning block 9. At this time, the clockwise and counterclockwise rotation of connecting shaft 6 are both limited. The connection of connecting shaft 4 and connecting shaft 6 is completed, making installation more convenient.

[0033] During disassembly, first rotate the moving ring 11 and then rotate the connecting shaft 6 in the opposite direction. At this time, the positioning block 9 can press the insertion rod 12, and the positioning rod 8 can rotate inside the positioning cylinder 5. Then, the connecting shaft 6 can be moved vertically to disassemble, making disassembly more convenient.

[0034] Example 2: This example provides a drilling device for exploration and design. In addition to the technical solutions of the above examples, it also has the following technical features: the outer surface of the connecting shaft 4 is slidably connected to the interior of the positioning ring 10 and the moving ring 11, and the outer surface of the positioning rod 8 is slidably connected to the inner wall of the positioning cylinder 5.

[0035] Among them, the positioning rod 8 and the positioning cylinder 5 can quickly connect the connecting shaft 4 and the connecting shaft 6, which facilitates the connection.

[0036] During installation, the positioning rod 8 is inserted into the positioning cylinder 5. At this time, the axes of connecting shaft 1 4 and connecting shaft 2 6 are aligned, reducing the problem of misalignment of the drill rod axes and making drilling more stable.

[0037] Example 3: This example provides a drilling device for exploration and design. In addition to the technical solutions of the above examples, it also has the following technical features: the inner wall of the positioning cylinder 5 is provided with a sliding groove 14 and a positioning groove 15, which are interconnected. The outer surface of the positioning block 9 is slidably connected to the inner wall of the sliding groove 14 and the positioning groove 15.

[0038] Among them, the positioning block 9 can move inside the slide groove 14 and the positioning groove 15, and can position the positioning rod 8.

[0039] The inlet of the slide 14 has rounded corners. When the positioning rod 8 enters the positioning cylinder 5, it is easier for the positioning block 9 to enter the slide 14 along the rounded corners. After the positioning block 9 moves to the top of the slide 14, the connecting shaft 6 rotates to allow the positioning block 9 to enter the positioning groove 15. At this time, the vertical movement of the connecting shaft 6 and the positioning rod 8 is limited by the positioning groove 15 and the positioning block 9.

[0040] Example 4: This example provides a drilling device for exploration and design. In addition to the technical solutions of the above examples, it also has the following technical features: the outer surface of the insertion rod 12 is slidably connected to the inner wall of the positioning groove 15, the outer surface of the insertion rod 12 is in contact with the outer surface of the positioning block 9, and the adjacent outer surfaces of the insertion rod 12 and the positioning block 9 are chamfered.

[0041] Among them, the insertion rod 12 can limit one side of the positioning block 9 and fix the positioning rod 8;

[0042] When the positioning block 9 moves to one side wall of the positioning groove 15, the insertion rod 12 contacts the positioning block 9. Since the insertion rod 12 can only move horizontally, the positioning block 9 will be limited by the circumference of the insertion rod 12. When the position of the insertion rod 12 is fixed, the circumferential rotation of the positioning block 9 is limited. When the positioning rod 8 is rotated, the insertion rod 12 and the positioning block 9 make oblique contact. At this time, under the action of the component force in one direction, the insertion rod 12 moves linearly, and the positioning block 9 can rotate.

[0043] Example 5: This example provides a drilling device for exploration and design. In addition to the technical solutions of the above examples, it also has the following technical features: multiple sets of insertion holes 16 are opened inside the connecting shaft 4, the insertion rod 12 moves linearly inside the insertion hole 16, and the baffle 13 is located between the positioning cylinder 5 and the insertion hole 16.

[0044] The insertion rod 12 can move inside the insertion hole 16, and the movement trajectory of the insertion rod 12 can be limited.

[0045] One end of the insertion rod 12 slides inside the insertion hole 16. At this time, the insertion rod 12 will move horizontally under the action of the insertion hole 16, making it more stable when limiting the positioning block 9.

[0046] Example 6: This example provides a drilling device for exploration and design. In addition to the technical solutions of the above examples, it also has the following technical features: the inner wall of the moving ring 11 is in contact with one end of the insertion rod 12; the outer surfaces of the moving ring 11 and the insertion rod 12 are both chamfered; when the moving ring 11 is in contact with one end of the insertion rod 12, the baffle 13 is in contact with the positioning cylinder 5.

[0047] Among them, the movable ring 11 can fix one end of the insertion rod 12 and further fix the positioning rod 8;

[0048] When connecting shaft 4 and connecting shaft 6 are connected, the control ring 11 rotates, causing the inner wall of the moving ring 11 to press against one end of the insertion rod 12. At this time, the insertion rod 12 moves into the interior of connecting shaft 4 under the oblique push, and the moving ring 11 can limit one end of the insertion rod 12. When the insertion rod 12 is fixed to the positioning block 9, the baffle 13 contacts the positioning cylinder 5. The baffle 13 ensures that the insertion rod 12 is always limited, preventing the insertion rod 12 from falling out of the interior of connecting shaft 4.

[0049] Example 7: This example provides a drilling device for exploration and design. In addition to the technical solutions of the above examples, it also has the following technical features: the upper and lower connecting shafts 6 and the spiral blades 7 are connected by connecting shaft 4 and connecting shaft 6, and one end of each connecting shaft 6 in the same group is provided with connecting shaft 4.

[0050] Among them, a set of connecting shaft 1 4 is installed at the lower end of connecting shaft 2 6 as an extension component. A set of small connecting shafts and plate structures are set at the bottom end of the overall spiral plate 7, which can set a tip and plate at the bottom end of the overall drill rod, making it convenient to cover the insertion hole 16 and carry out overall soil breaking operation.

[0051] Working principle: When connecting the upper and lower connecting shaft 4 and connecting shaft 6, the control positioning rod 8 enters the interior of the positioning cylinder 5. At this time, the positioning block 9 moves inside the slide groove 14. When the positioning block 9 moves to the top of the slide groove 14, the positioning rod 8 is rotated to make the positioning block 9 enter the interior of the positioning groove 15. Then, the moving ring 11 is rotated to make the moving ring 11 contact one end of the insertion rod 12, causing the insertion rod 12 to move towards the positioning cylinder 5, so that the insertion rod 12 enters the interior of the positioning groove 15 and is located on one side of the positioning block 9. At this time, the rotation of the positioning block 9 is restricted, and the connecting shaft 4 and connecting shaft 6 will not easily rotate after the whole assembly.

[0052] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
