Description

Technical Field

[0001] This utility model belongs to the field of drilling tool technology, specifically a drilling tool for geological exploration. Background Technology

[0002] In the early stages, surface observation relied on tools such as geological hammers and compasses, combined with geophysical exploration, geochemical prospecting, and basic methods such as elemental analysis and drilling sampling.

[0003] In the existing technology, CN219344621U describes a drilling tool suitable for geological exploration of pegmatite-type lithium deposits. It includes a disc with a drilling assembly installed at its center. Four grooves are formed on the arc surface of the disc, and an adjustment structure is installed on the inner wall of each groove. The adjustment structure includes a rotating shaft with both ends rotatably connected to the inner wall of the groove. A slide rail is fixedly connected to the arc surface of the rotating shaft, and a slider is slidably connected inside the slide rail. A fixing block is fixedly connected to one side of the slide rail near its upper end, and an adjusting screw is rotatably connected inside the fixing block. A handle is fixedly connected to the upper end of the adjusting screw, and the lower end of the adjusting screw passes through the fixing block and is threadedly connected to it. A support assembly is installed at the lower end of the slider. This application has the advantage of stable drilling on weathered and soft surfaces during geological exploration of pegmatite-type lithium deposits.

[0004] Existing drilling tools for geological exploration typically require drilling rigs to rotate the drill bit at high speeds for drilling operations. However, common drilling rigs cannot be intelligently controlled to start when drilling is required. Therefore, a new drilling tool for geological exploration is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background art, this utility model proposes a drilling tool for geological exploration.

[0007] Preferably, a drilling motor is fixedly connected to the bottom of the built-in rod; the drilling motor is electrically connected to a pressure switch; and a drill bit is fixedly connected to the output end of the drilling motor.

[0008] Preferably, a connecting rod is fixedly connected to the outer wall of the drilling body; a fixing frame is fixedly connected to the bottom of the connecting rod.

[0009] Preferably, a servo motor is mounted on the side of the mounting bracket; the output end of the servo motor is fixedly connected to a double-threaded screw.

[0010] Preferably, the outer wall of the double-threaded screw is threaded with a sliding block; the bottom of the sliding block is rotatably connected with a rotating support rod.

[0011] Preferably, an auxiliary block is rotatably connected to the bottom of the rotating support rod; a sliding rod is fixedly connected to the top of the auxiliary block.

[0012] Preferably, an outer block is slidably connected to the outer wall of the sliding rod; the outer block is fixedly connected to the outer wall of the fixing frame.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a drilling tool for geological exploration. By setting a hydraulic device to drive the trigger body to move downward, and setting an internal rod that can slide on the inner surface of the trigger body, the internal rod can abut against a pressure switch to trigger the tool, making the starting of the drilling tool more intelligent.

[0015] This utility model provides a drilling tool for geological exploration. By setting a servo motor to drive the double-threaded screw to rotate, the sliding blocks move closer to each other. This allows the auxiliary block to be stopped by the sliding rod and then pushed down by the rotating support rod, so that the drilling tool can better adapt to the environment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-4 This utility model provides a drilling tool for geological exploration, including a drilling body 1; a hydraulic device 2 is installed on the top of the drilling body 1; a trigger body 8 is fixedly connected to the output end of the hydraulic device 2; a pressure switch 9 is installed on the inner wall of the trigger body 8; a fixing block 10 is fixedly connected to the outer wall of the trigger body 8; an internal rod 11 is slidably connected to the inner wall of the trigger body 8; a connecting block 12 is fixedly connected to the outer wall of the internal rod 11; a damping rod 13 is fixedly connected to the top of the connecting block 12; the damping rod 13 is slidably connected to the inner wall of the fixing block 10; a return spring 14 is fixedly connected to the fixing block 10 through the connecting block 12; during operation, after the hydraulic device 2 is started, the trigger body 8 can drive the drill bit 7 to descend synchronously. At this time, the internal rod 11 will slide on the inner wall of the trigger body 8, and at the same time, the damping rod 13 will slide with the fixing block 10, thereby causing the return spring 14 to be in a compressed state until the internal rod 11 abuts against the pressure switch 9, so that the pressure switch 9 is activated and the drilling structure is opened.

[0027] Furthermore, such as Figure 2 and Figure 4As shown, a drilling motor 6 is fixedly connected to the bottom of the built-in rod 11; the drilling motor 6 is electrically connected to the pressure switch 9; a drill bit 7 is fixedly connected to the output end of the drilling motor 6; a connecting rod 3 is fixedly connected to the outer wall of the drilling body 1; a fixing frame 4 is fixedly connected to the bottom of the connecting rod 3; a servo motor 5 is mounted on the side of the fixing frame 4; a double-threaded screw 15 is fixedly connected to the output end of the servo motor 5; a sliding block 20 is threadedly connected to the outer wall of the double-threaded screw 15; a rotating support rod 16 is rotatably connected to the bottom of the sliding block 20; an auxiliary block 17 is rotatably connected to the bottom of the rotating support rod 16; a sliding rod 19 is fixedly connected to the top of the auxiliary block 17; an external block 18 is slidably connected to the outer wall of the sliding rod 19; and the external block 18 is fixedly connected to the outer wall of the fixing frame 4. During operation, after starting the servo motor 5, the double-threaded screw 15, which has a mirrored thread along the middle part, rotates and drives the sliding blocks 20 to move closer to each other. At the same time, because the rotating support rod 16 is rotatably connected between the sliding block 20 and the auxiliary block 17, the auxiliary block 17 can move smoothly downward under the limit of the external block 18 and the sliding rod 19.

[0028] Working principle: After the hydraulic unit 2 is started, the trigger body 8 can drive the drill bit 7 to descend synchronously. At this time, the built-in rod 11 will slide on the inner wall of the trigger body 8, and at the same time, the damping rod 13 will slide with the fixed block 10, thereby causing the return spring 14 to be in a compressed state until the built-in rod 11 abuts against the pressure switch 9, so that the pressure switch 9 is activated and the drilling structure is opened. After the servo motor 5 is started, the double threaded screw 15 with a mirror thread along the middle part can rotate and drive the sliding blocks 20 to move closer to each other. At the same time, because the rotating support rod 16 is rotatably connected between the sliding block 20 and the auxiliary block 17, the auxiliary block 17 can move smoothly downward under the limit of the outer block 18 and the sliding rod 19.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
