Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices for exploration, and particularly relates to a sampling device for geological and mineral exploration. Background Technique

[0002] Geological exploration is an investigation and detection activity of geology through various means and methods to determine a suitable bearing stratum, determine the foundation type according to the foundation bearing capacity of the bearing stratum, and calculate the foundation parameters. During the process of geological exploration, it is necessary to sample and study mineral resources.

[0003] In the prior art, when sampling for geological and mineral exploration, it is often necessary to drill holes to explore deep minerals. Such a device, such as a sampling device for geological and mineral exploration with the application number 202221454272.5, can drill holes for geological and mineral exploration sampling during use. However, this device can only sample vertically downward and cannot sample horizontally as needed. For example, when sampling deep in a mine, its use effect is limited. Therefore, an improved sampling device for geological and mineral exploration is needed to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sampling device for geological and mineral exploration to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A sampling device for geological and mineral exploration, including a workbench. A drilling mechanism for drilling and sampling is arranged at the upper end of the workbench. The drilling mechanism includes a fixed frame, a rotating frame, a slide rail, a movable frame, a first motor, a connector, and a drill rod. A fixed frame is fixedly arranged on one side of the upper end of the workbench. The upper end of the fixed frame is movably arranged with a rotating frame through a rotating shaft. A slide rail is fixedly arranged at the upper end of the rotating frame. The outer surface of the slide rail is movably engaged with a movable frame. A first motor is fixedly arranged at the upper end of the movable frame. The output shaft end of the first motor is fixedly arranged with a connector through a coupling. A drill rod is fixedly arranged at one end of the connector away from the first motor. A transmission mechanism for driving the rotation of the rotating frame is arranged on the upper end of the workbench on one side of the fixed frame.

[0006] Preferably, the transmission mechanism includes a worm gear, a second motor, and a worm. One end of the rotating shaft where the rotating frame is located is fixedly provided with a worm gear. A second motor is fixedly arranged on the upper end of the workbench on one side of the worm gear. The output shaft end of the second motor is fixedly arranged with a worm through a coupling. Through the transmission mechanism, it is convenient to drive the rotation of the rotating frame, so as to drive the rotation of the rotating frame and all the components above the rotating frame.

[0007] Preferably, a hydraulic cylinder is fixedly arranged inside the slide rail, and the movable end of the hydraulic cylinder is fixedly connected to the movable frame. A through groove is opened in the middle of the surface of the slide rail, and the movable frame and all components on the surface of the movable frame can be driven to translate along the slide rail through the extension and contraction of the hydraulic cylinder, and the through groove can facilitate the connection between the movable frame and the movable end of the hydraulic cylinder without causing motion interference.

[0008] Preferably, the worm wheel and the worm are meshingly connected to each other, and the helix lead angle of the worm is smaller than the equivalent friction angle between the meshing teeth of the worm and the worm wheel. By making the helix lead angle of the worm smaller than the equivalent friction angle between the meshing teeth of the worm and the worm wheel, the worm wheel and the worm can play a self-locking role, ensuring that the worm wheel rotates only when the screw rotates, and the worm and the worm wheel will not rotate if the worm does not rotate, thereby ensuring the stability of the rotating frame.

[0009] Preferably, supporting feet are fixedly provided at the four corners of the lower end surface of the workbench, and the supporting feet can provide a stable supporting force for the workbench.

[0010] Preferably, a telescopic rod is movably provided on the surface of the workbench through a rotating shaft, and the movable end of the telescopic rod is movably connected to the slide rail through the rotating shaft, so that the left and right stability of the slide rail can be ensured by the telescopic rod; at the same time, both ends of the telescopic rod are movably connected through the rotating shaft, which will not affect the rotation of the slide rail and the rotating frame.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model can sample vertically or horizontally as needed or can be adjusted within the vertical and horizontal range. During adjustment, the worm can be driven to rotate by the motor, and then the worm can drive the worm wheel to rotate, thereby driving the rotating frame and all the components on the upper end of the rotating frame to rotate, so that the angle of the first motor and the drill rod can be adjusted. In this way, vertical sampling can be carried out as needed, thereby facilitating drilling and sampling of the underground. Correspondingly, horizontal sampling can also be carried out as needed, which can improve the sampling effect of the device.

[0013] 2. When the utility model is used, the angle of the movable frame can be easily adjusted and fixed. Since the helix angle of the worm is smaller than the equivalent friction angle between the meshing teeth of the worm and the worm wheel, the worm wheel and the worm can play a self-locking role, ensuring that the worm wheel rotates only when the screw rotates, while the worm and the worm wheel will not rotate if the worm does not rotate, thereby ensuring the stability of the rotating frame after each angle adjustment.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a sampling device for geological and mineral exploration, including a workbench 1, a drilling mechanism for drilling and sampling is arranged at the upper end of the workbench 1. The drilling mechanism includes a fixed frame 2, a rotating frame 3, a slide rail 4, a movable frame 5, a first motor 6, a connector 7, and a drill pipe 8. A fixed frame 2 is fixedly arranged on one side of the upper end of the workbench 1. The rotating frame 3 is movably arranged at the upper end of the fixed frame 2 through a rotating shaft. A slide rail 4 is fixedly arranged at the upper end of the rotating frame 3. A movable frame 5 is movably engaged on the outer surface of the slide rail 4. A first motor 6 is fixedly arranged at the upper end of the movable frame 5. A connector 7 is fixedly arranged at the output shaft end of the first motor 6 through a coupling. A drill pipe 8 is fixedly arranged at one end of the connector 7 away from the first motor 6. A transmission mechanism for driving the rotation of the rotating frame 3 is arranged on one side of the fixed frame 2 at the upper end of the workbench 1.

[0021] The transmission mechanism includes a worm gear 9, a second motor 10, and a worm 11. The worm gear 9 is fixedly arranged at one end of the rotating shaft where the rotating frame 3 is located. The second motor 10 is fixedly arranged on the upper end of the workbench 1 on one side of the worm gear 9. The output shaft end of the second motor 10 is fixedly arranged with a worm 11 through a coupling. The transmission mechanism can conveniently drive the rotating frame 3 to rotate, thereby driving the rotating frame 3 and all the components on the upper end of the rotating frame 3 to rotate;

[0022] A hydraulic cylinder 12 is fixedly arranged inside the slide rail 4, and the movable end of the hydraulic cylinder 12 is fixedly connected to the movable frame 5. A through groove 13 is opened in the middle of the surface of the slide rail 4. The movable frame 5 and all parts on the surface of the movable frame 5 can be driven to translate along the slide rail 4 through the extension and contraction of the hydraulic cylinder 12, and the through groove 13 can facilitate the movable frame 5 to pass through the slide rail 4 and the movable end of the hydraulic cylinder 12 for connection without motion interference;

[0023] The worm wheel 9 and the worm 11 are meshed and connected with each other, and the helix lead angle of the worm 11 is smaller than the equivalent friction angle between the meshing teeth of the worm 11 and the worm wheel 9. By making the helix lead angle of the worm 11 smaller than the equivalent friction angle between the meshing teeth of the worm 11 and the worm wheel 9, the worm wheel 9 and the worm 11 can play a self-locking role, ensuring that the worm wheel 9 is driven to rotate only when the screw rotates, and the worm 11 does not rotate and the worm wheel 9 does not rotate, thereby ensuring the stability of the rotating frame 3;

[0024] The four corners of the lower surface of the workbench 1 are fixedly provided with supporting feet 14, which can provide a stable supporting force for the workbench 1;

[0025] A telescopic rod 15 is movably provided on the surface of the workbench 1 through a rotating shaft. The movable end of the telescopic rod 15 is movably connected to the slide rail 4 through the rotating shaft. The left and right stability of the slide rail 4 can be ensured by the telescopic rod 15. At the same time, both ends of the telescopic rod 15 are movably connected through the rotating shaft, which will not affect the rotation of the slide rail 4 and the rotating frame 3.

[0026] Working principle: When the device is used, the first motor 6 is rotated to drive the drill rod 8 to rotate, and then the first motor 6 and the drill rod 8 are pushed to translate along the slide rail 4 by the extension of the hydraulic cylinder 12, so that the area to be sampled can be drilled and sampled;

[0027] When sampling, vertical sampling, horizontal sampling or adjustment within the vertical and horizontal ranges can be performed according to needs. When adjusting, the motor drives the worm 11 to rotate, and then the worm 11 drives the worm gear 9 to rotate, so as to drive the rotating frame 3 and all the components at the upper end of the rotating frame 3 to rotate, thereby adjusting the angles of the first motor 6 and the drill pipe 8. In this way, vertical sampling can be carried out according to needs, which is convenient for drilling and sampling the ground. Correspondingly, horizontal sampling can also be carried out according to needs, so as to improve the sampling effect of the device;

[0028] At the same time, when the device is in use, the angle of the movable frame 5 is convenient to adjust and fix. Since the helix angle of the worm 11 is smaller than the equivalent friction angle between the meshing teeth of the worm 11 and the worm gear 9, the worm gear 9 and the worm 11 can play a self-locking role, ensuring that only when the screw rotates, the worm gear 9 is driven to rotate, and the worm 11 does not rotate and the worm gear 9 will not rotate, so as to ensure the stability of the rotating frame 3 after each angle adjustment.
