Description

Technical Field

[0001] The utility model relates to the field of core sampling devices, in particular to a drilling core cutting and splitting sampling device. Background Art

[0002] In geological exploration and civil engineering, it is often necessary to obtain core samples from underground for analysis to understand the structure and physical properties of the strata. Traditional core sampling methods usually include semi-automatic cutting and splitting processes. However, the diameters of the cylindrical centers drilled by mechanical core drills during prospecting are uneven. When a single-size splitting tube is used for cutting, when the diameter of the splitting tube differs greatly from that of the core, it is easy to cause danger during cutting and may cause harm to the operator.

[0003] The patent with announcement number CN220548483U discloses a core sawing and cutting device for hard rock, which mainly includes a frame, a motor, a cutting device, a splitting device and a water supply device. The frame serves as the main supporting structure, and a cutting frame and a splitting frame are provided on its workbench. The motor is arranged at the lower part of the workbench, and the power is transmitted to the cutting saw blade of the cutting device through the cooperation of the active pulley and the belt. The cutting saw blade is used to split the core of hard rock. In order to ensure the safety of the operator, the outer circumference of the cutting saw blade is covered with a protective cover, and a water supply interface is also provided at the front of the protective cover. The splitting device is assembled on the splitting frame, and the position of the cutting saw blade is just in the vertical plane of the core axis of the hard rock. When the core of the hard rock is moved from top to bottom, the rotating cutting saw blade cuts the core of the hard rock into two halves.

[0004] In addition, the splitting device in the patent has good adaptability and can replace the splitting tube according to the cores of hard rocks of different diameters. The splitting tube seat is provided with different size specifications. When the splitting tube is applied to the cores of hard rocks of different diameters, the splitting tube seat of the corresponding specification needs to be replaced to perform the core sawing and splitting operation. However, the existing splitting tube seat cannot realize the fixing process of multiple splitting tubes of different sizes at the same time, which leads to a small scope of application and the replacement process of the splitting tube seat is cumbersome. This undoubtedly increases the complexity of the operation and affects the work efficiency.

[0005] In view of this, how to change the current situation that the existing split tube seat cannot be applied to split tubes of various sizes has become a technical problem that technical personnel in this field need to solve urgently. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] Reference Figure 1-4 The utility model provides a drilling core cutting and splitting sampling device, which comprises a workbench 1, a cutting assembly, a splitting tube 2 and two groups of splitting tube seats. The workbench 1 serves as the basic platform of the entire device. The cutting assembly is arranged on the workbench 1 and is responsible for cutting the core. The splitting tube 2 is designed with a saw blade groove 3 that is transparent from top to bottom along its axial direction, so that the cutting assembly can smoothly pass through the saw blade groove 3 to achieve accurate cutting of the core. The two groups of splitting tube seats are respectively located at the two ends of the splitting tube 2 and are arranged on the workbench 1. Each group of splitting tube seats comprises a positioning plate 4, a driving ring 5 and a clamping rod 7. The positioning plate 4 is fixedly connected to the workbench 1 and is designed with a through hole to enable the splitting tube 2 to pass through. The driving ring 5 is coaxially rotatably connected to the through hole, and a protrusion 6 is arranged on the end face of the driving ring 5. The number of the clamping rods 7 is several, and the several clamping rods 7 are distributed in a circular array along the center of the through hole. One end of each clamping rod 7 is fixedly connected to the positioning plate 4, and a sliding groove 8 is provided in the middle thereof, and these sliding grooves 8 cooperate with the protrusions 6 on the driving ring 5 to achieve a one-to-one corresponding sliding connection. When the driving ring 5 rotates, the other end of the clamping rod 7 can be driven to move toward or away from the center of the through hole, thereby selectively clamping the outer tube wall of the split tube 2.

[0043] Preferably, the other end of the clamping rod 7 is designed with a hinged clamping seat 9, and the end surface of these clamping seats 9 away from the clamping rod 7 is arc-shaped, which is used to clamp the outer tube wall of the split tube 2. The outer wall of the driving ring 5 extends in a direction away from the through hole to form a protrusion 10, and a threaded sleeve 11 is rotatably connected to the protrusion 10. At the same time, a positioning sleeve 12 is also rotatably connected to the positioning plate 4, and a threaded rod 13 is rotatably connected to the positioning sleeve 12. The threaded rod 13 is connected to the threaded sleeve 11 through a threaded connection, so that the position of the clamping seat 9 can be adjusted by rotating the threaded rod 13 to move toward or away from the center of the through hole.

[0044] In order to improve the clamping effect and enable the positioning sleeve 12 to quickly move toward or away from the center of the through hole, the clamping rod 7 and the sliding groove 8 are both designed to be arc-shaped.

[0045] In addition, a positioning block 14 is fixedly connected to the workbench 1 and is located below the split tube 2. The positioning block 14 is designed with a movable head of a bolt 15, and the screw of the bolt 15 can selectively penetrate the saw blade groove 3 and be threadedly connected with the nut 16, further ensuring the stability and accuracy of the operation.

[0046] When in use, first, pass the split tube 2 through the through holes of the two groups of split tube seats; then, by turning the bolt 15, the bolt 15 passes through the saw blade groove 3 and is threadedly connected to the nut 16; secondly, by rotating the threaded rod 13, the clamping seat 9 moves toward the center of the through hole, thereby clamping the clamping seat 9 on the outer wall of the split tube 2; finally, release the nut 16 on the bolt 15, and flip the nut 16 to remove it from the saw blade groove 3. Through the above operations, the bolt 15 can pass through the axis of the split tube 2, and can ensure that the saw blade groove 3 after installation is transparent from top to bottom. Compared with the traditional positioning of the split tube 2, the positioning process of the saw blade groove 3 is more accurate, reduces the operation of repeated adjustments, and improves work efficiency.

[0047] The specific structure of the cutting assembly includes a flip base 17, a vertical side wall 20, a drive motor 18, a transmission shaft 21 and a cutting saw blade 24. Among them, one end of the flip base 17 is hinged to the workbench 1, and a drive motor 18 is installed thereon to provide cutting power; the vertical side wall 20 is perpendicular to the flip base 17, and the vertical side wall 20 is fixedly connected to the flip base 17, and a transmission shaft 21 is rotatably connected thereto.

A driven pulley 22 is also installed on the transmission shaft 21, and the two are connected by a belt 23 to ensure the effective transmission of power.

[0048] In addition, the cutting assembly also includes a slide rail 25 fixedly connected to the workbench 1, a sliding block 26 slidably connected to the slide rail 25 along the axial direction of the dissecting tube 2, and a first connecting rod 27 connecting the sliding block 26 and the lower surface of the flip base 17. By sliding the sliding block 26 along the slide rail 25, the inclination angle of the flip base 17 can be adjusted, and at the same time, the cutting saw blade 24 can selectively penetrate the saw blade groove 3.

[0049] In addition, the cutting assembly also includes a mounting plate 28 and a driving screw 29. The mounting plate 28 is vertically fixedly connected to the slide rail 25, and the middle part is rotatably connected to the driving screw 29. The driving screw 29 is arranged parallel to the splitting tube 2, and one end of the driving screw 29 is threadedly connected to the sliding block 26. By rotating the driving screw 29, the position of the sliding block 26 can be accurately controlled; the other end of the driving screw 29 passes through the mounting plate 28 and is fixedly connected to a hand wheel 30 for the convenience of manual adjustment by the operator. By rotating the hand wheel 30, the driving screw 29 can be rotated, further driving the sliding block 26 to slide along the slide rail 25, and further changing the inclination angle of the flip base 17.

[0050] For dust protection and safety considerations, the cutting assembly further includes a dust cover 31, which is designed to cover the upper area of ​​the cutting saw blade 24. The dust cover 31 is fixedly connected to the vertical side wall 20 through a second connecting rod 32.
