Description

Technical Field

[0001] This utility model relates to a mining exploration sampling device, specifically an adjustable sampling length mining exploration sampling device, belonging to the field of mining exploration sampling technology. Background Technology

[0002] Mining exploration sampling is a core part of mineral resource evaluation and development. Appropriate methods should be selected based on the characteristics of the ore body, the exploration stage, and the purpose of testing. Mining sampling involves collecting representative samples from the ore body, surrounding rock, and mine products according to specific specifications and requirements based on the needs of mineral exploration, mining, and quality management.

[0003] The utility model patent CN216116829U relates to a rock sampling device for mining geology. It includes a square frame drag handle, a pull rod, a hollow sleeve column, a fixed handle, a connecting rod, a hollow fixed column, a mechanical claw, a limiting rod, a movable rod, and a spring. The movable pull rod can be positioned to move up and down, so that the mechanical claw opens and closes under the linkage of the crank of the connecting rod and the movable rod to release and pick up the sample. It has the advantages of simple structure, good fixed anti-slip effect, large expansion range, high working efficiency and safety, and is suitable for application in the mining and metallurgical geology industry.

[0004] When sampling in mine exploration, it is necessary to grasp the ore. Although the sampling device in the aforementioned patent improves the firmness of the grasp, it is not suitable for large mechanical claws. When grasping larger ores, the mechanical claws do not have enough flexibility, which can easily lead to poor gripping effect on larger ores. To address this issue, we provide a mine exploration sampling device with adjustable sampling length to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a mine exploration sampling device with adjustable sampling length to solve the above-mentioned problems, thereby addressing the issue of poor ore gripping effect in the prior art.

[0006] This utility model is achieved through the following technical solution: a mining exploration sampling device with adjustable sampling length.

[0007] The device includes a connecting compartment, at the bottom of which are equidistantly arranged gripping mechanisms. Each gripping mechanism includes a clamping rod and a linkage rod. An extension rod is slidably connected inside the clamping rod. A power mechanism is located in the middle of the connecting compartment. The power mechanism includes a lifting rod. Both ends of the linkage rod are rotatably connected to the lifting rod and the clamping rod, respectively.

[0008] Preferably, a connecting sleeve is fixedly connected to the top of the connecting chamber, the top of the clamping rod is rotatably connected to the connecting chamber, and a positioning clamp finger is fixedly connected to the bottom of the extension rod. The connecting chamber is fixedly connected to the delay rod or the lifting rope through the connecting sleeve, which facilitates the sampling of ore on the ground or inside the pit.

[0009] Preferably, the clamping rod is internally rotatably connected to an adjusting screw, and the extension rod is provided with an internal thread corresponding to the adjusting screw. The adjusting screw is threadedly connected to the extension rod. The length of the adjusting screw is greater than the length of the clamping rod. By rotating the adjusting screw, the extension rod is moved to extend out of the clamping rod. The relatively long length of the adjusting screw provides support and fixation for the extension rod when it is extended, thereby improving the load-bearing capacity of the extension rod.

[0010] Preferably, a first bevel gear is fixedly connected to the top end of the adjusting screw, the first bevel gear is meshed with a second bevel gear, and the second bevel gear is rotatably connected to the clamping rod. The first bevel gear is rotated by controlling the rotation of the second bevel gear, which drives the adjusting screw to rotate, so as to facilitate the adjustment of the position of the extension rod.

[0011] Preferably, a connector is fixedly connected to the middle of the second bevel gear, one end of which is bolt-shaped and located outside the clamping rod, making it convenient for workers to control the rotation of the second bevel gear with a wrench; the surface of the extension rod is provided with scale lines, making it convenient to adjust and observe the length of the extension rod extending out of the clamping rod.

[0012] Preferably, a limiting tube is sleeved on the outside of the lifting rod, and the limiting tube is fixedly connected to the connecting chamber. An adjusting block is fixedly connected to the top of the lifting rod. The lifting rod is fixed by the limiting tube. The lifting rod is square, so that the lifting rod can only slide up and down, avoiding rotation of the lifting rod and improving the stability of the lifting rod.

[0013] Preferably, the adjusting block is externally threaded with a rotating sleeve, and the bottom end of the rotating sleeve is rotatably connected to the connecting chamber. The connecting chamber is internally fixedly connected with a motor, and the output end of the motor is fixedly connected to the rotating sleeve. The rotating sleeve is controlled to rotate by the motor, so that the adjusting block drives the lifting rod to move up and down.

[0014] This utility model provides a mine exploration sampling device with adjustable sampling length, which has the following beneficial effects: 1. This adjustable sampling length mining exploration sampling device uses a linkage rod to move a clamping rod, allowing the clamping rod to grip the ore. When larger ores need to be gripped, the length of the clamping rod can be extended using an extension rod, increasing the ore gripping range of the sampling device and improving its practicality. A lifting rod moves one end of the linkage rod upward, causing the other end of the linkage rod to bring the bottom of the lifting rod closer together to grip the ore. The combination of extension and expansion makes the gripping of rocks more effective.

[0015] 2. This adjustable sampling length mining exploration sampling device, through a connecting sleeve, fixes the connecting chamber to the extension rod or lifting rope together, facilitating the sampling of ore from the ground or inside pits. By rotating the adjusting screw, the extension rod is moved, extending out of the clamping rod. The adjusting screw is relatively long, providing support and fixation for the extension rod when it is extended, improving its load-bearing capacity and ensuring sufficient mechanical strength to clamp the ore when extended. The second bevel gear controls the rotation of the first bevel gear, which in turn drives the adjusting screw to rotate, facilitating the adjustment of the extension rod's position.

[0016] 3. This adjustable sampling length mining exploration sampling device, through a connector, allows workers to easily control the rotation of the second bevel gear using a wrench. By observing the scale markings at the bottom of the clamping rod, it is easy to position the extension length of the expansion rod, thus ensuring that multiple expansion rods have equal adjustable lengths. The lifting rod is fixed by a limiting tube, and the square shape of the lifting rod allows it to slide only up and down, preventing rotation and improving the stability of the lifting rod. The rotating sleeve is controlled by a motor to rotate, causing the adjusting block to move the lifting rod up and down. After the adjusting block is adjusted, the rotating sleeve and connecting chamber rotate to provide support for the rotating sleeve. The self-locking capability of the threaded connection between the adjusting block and the rotating sleeve prevents the adjusting block from moving arbitrarily. Attached Figure Description

[0019] This utility model provides a mining exploration sampling device with adjustable sampling length.

[0020] Please see Figure 1 , Figure 2 and Figure 3 The device includes a connecting compartment 1, at the bottom of which are equidistantly arranged gripping mechanisms 3. Each gripping mechanism 3 includes a clamping rod 301 and a linkage rod 305. An extension rod 302 is slidably connected inside the clamping rod 301. The linkage rod 305 drives the clamping rod 301 to move, allowing the clamping rod 301 to grip the ore. When it is necessary to grip larger pieces of ore, the extension rod 302 can be used to extend the length of the clamping rod 301, increasing the ore gripping range of the sampling device and improving its practicality.

[0021] The top of the connecting chamber 1 is fixedly connected to the connecting sleeve 2. The top of the clamping rod 301 is rotatably connected to the connecting chamber 1. The bottom of the extension rod 302 is fixedly connected to the positioning clamp finger 303. The connecting chamber 1 is fixedly connected to the delay rod or the lifting rope through the connecting sleeve 2, which facilitates the sampling of ore on the ground or inside the pit. The ore is clamped and fixed through the positioning clamp finger 303.

[0022] An adjusting screw 306 is rotatably connected inside the clamping rod 301, and the adjusting screw 306 is threadedly connected to the extension rod 302. The length of the adjusting screw 306 is greater than the length of the clamping rod 301. By rotating the adjusting screw 306, the extension rod 302 is moved, extending out of the clamping rod 301. Since the adjusting screw 306 is relatively long, it maintains thread engagement with the extension rod throughout the entire extension process. Together with the radial guidance support of the inner wall of the clamping rod, it provides stable axial load-bearing and radial fixation for the extension rod, improving its load-bearing capacity and ensuring that the extension rod 302 can provide sufficient mechanical strength to clamp the ore when extended.

[0023] The top end of the adjusting screw 306 is fixedly connected to a first bevel gear 307, which is meshed with a second bevel gear 308. The second bevel gear 308 is rotatably connected to the clamping rod 301. The first bevel gear 307 is rotated by the second bevel gear 308, which drives the adjusting screw 306 to rotate, so as to facilitate the adjustment of the position of the extension rod 302.

[0024] A connector 309 is fixedly connected to the middle of the second bevel gear 308, and a scale line 304 is fixedly connected to the surface of the extension rod 302. The scale line 304 is slidably connected to the inner wall of the clamping rod 301. Through the connector 309, it is convenient for the operator to control the rotation of the second bevel gear 308 with a wrench. By observing that the scale line 304 is located at the bottom of the clamping rod 301, it is convenient to locate the extension length of the extension rod 302, so that the adjustment lengths of multiple extension rods 302 are equal.

[0025] Please refer to it again. Figure 1 , Figure 2 ,and Figure 4 A power mechanism 4 is provided in the middle of the connecting chamber 1. The power mechanism 4 includes a lifting rod 401. The two ends of the linkage rod 305 are rotatably connected to the lifting rod 401 and the clamping rod 301, respectively. The lifting rod 401 drives one end of the linkage rod 305 to move upward, so that the other end of the linkage rod 305 drives the bottom end of the lifting rod 401 to move closer to each other, thereby clamping the ore.

[0026] A limiting tube 402 is fitted around the lifting rod 401, and the limiting tube 402 is fixedly connected to the connecting chamber 1. An adjusting block 403 is fixedly connected to the top of the lifting rod 401. The lifting rod 401 is fixed by the limiting tube 402. The lifting rod 401 is square, so it can only slide up and down, thus limiting the circumferential and radial movement of the power mechanism, preventing rotation and swaying of the lifting rod, and improving the stability of the lifting rod 401. The threaded pair between the adjusting block and the rotating sleeve has a self-locking characteristic, which can maintain the position of the lifting rod after the motor stops, thereby maintaining the clamping force and preventing the clamp from loosening.

[0027] The adjusting block 403 is externally threaded with a rotating sleeve 404, and the bottom end of the rotating sleeve 404 is rotatably connected to the connecting chamber 1. The connecting chamber 1 is internally fixedly connected with a motor 405, and the output end of the motor 405 is fixedly connected to the rotating sleeve 404. The rotating sleeve 404 is rotated by the motor 405, which causes the adjusting block 403 to drive the lifting rod 401 to move up and down. After the position of the adjusting block 403 is adjusted, the rotating sleeve 404 can be supported by rotating with the connecting chamber 1. The self-locking capability of the threaded connection between the adjusting block 403 and the rotating sleeve 404 can prevent the adjusting block 403 from moving arbitrarily.

[0028] Motor 405 is a small motor, which can be an RC520 type motor. Motor 405 is connected to an external remote control via radio. The matching remote control can control the operation or stop of motor 405. A resistance sensor is fixedly connected to the output end of motor 405. When the positioning gripper 303 clamps the ore, the rotation of motor 405 is automatically stopped to avoid overload operation of motor 405 and damage to motor 405, thereby improving the stability of motor 405 operation.

[0029] Working principle: When it is necessary to grab ore from the ground or the top of the mine, the rod is screwed to the connecting sleeve 2 for easy grabbing of ore. When it is necessary to sample ore from deep underground, the connecting sleeve 2 is screwed to the connecting buckle at one end of the rope for easy sampling of deep ore via the rope. When sampling large ore, the connecting head 309 is rotated by the wrench, causing the second bevel gear 308 to control the first bevel gear 307 to rotate, which in turn drives the adjusting screw 306 to rotate. By checking the scale line 304, the multiple extension rods 302 are adjusted to the appropriate length. The rotating sleeve 404 is controlled by the motor 405. The adjustment block 403 drives the lifting rod 401 downward, and the linkage rod 305 squeezes the clamping rod 301, causing the positioning clamping fingers 303 to move away from each other and move the device above the ore. The motor 405 controls the rotating sleeve 404 to rotate, causing the adjustment block 403 to drive the lifting rod 401 upward, and the linkage rod 305 pulls the clamping rod 301, causing the positioning clamping fingers 303 to move closer to each other and grab the ore. By moving the connecting chamber 1, the ore grabbing and sampling operation is completed. By adjusting the length of the clamping rod 301, it can meet the sampling and grabbing work of ores of various sizes and shapes, increasing the tension range of the device and improving the practicality of the sampling device.
