[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a technical solution: an automatic core sampling machine for rock core preparation, including a base 1, a support column 3, a guide rail 4, a cooling assembly 8, and a bracket 9. The base 1 has four casters 2 on its top surface, facilitating flexible movement of the equipment within the work area and allowing for quick position adjustments according to different operational needs. The support column 3 is vertically positioned on one side of the top of the base 1, with a limit block at its top. The limit block extends above a slider 5, effectively limiting the upward movement range of the slider 5 and preventing it from detaching from the guide rail 4 during operation, thus ensuring the safety and stability of the equipment. A guide rail 4 is installed on one side of the support column 3, and a slider 5 slides on the guide rail 4. The guide rail 4, through the slider 5, slides in conjunction with a driver 6, allowing the driver 6 to move horizontally along a predetermined vertical direction. The drive unit moves steadily up and down, thus precisely controlling the lifting position of the drill bit 7 to meet the requirements of coring rocks at different depths. The drill bit 7 is installed at the bottom of the drive unit 6. The drive unit 6 serves as the power source for rotating the drill bit 7. The drill bit 7 directly acts on the rock surface to perform coring operations. The output power and speed can be adjusted according to the hardness characteristics of different rocks to ensure that the drill bit 7 can effectively cut and drill on various rock materials. A support rod 11 is installed on the other side of the support column 3 to provide auxiliary support and enhance the stability of the entire structure. It can share some of the lateral force and torque generated by the force on the drill bit 7, preventing the support column 3 from deforming or being damaged due to excessive force on one side. This further ensures the reliability and durability of the equipment during long-term, high-intensity coring operations.
[0022] There are two supports 9, which are vertically installed at both ends of the support column 3. These supports effectively expand the vibration isolation function, absorbing the vibrations generated by the high-speed rotation of the drill bit 7 cutting the rock during core sampling. This prevents the vibrations from being transmitted to the base 1 and the entire equipment structure, reducing loosening and wear of equipment parts caused by vibration, and minimizing adverse effects on core sampling accuracy. This ensures the stability and reliability of the equipment operation and also reduces noise generated during operation. Furthermore, the supports enhance the lateral support range and stability of the equipment. Spring vibration isolators 10 are installed at the bottom of the supports 9. The spring isolator 10 utilizes the elastic deformation of a spring to interrupt the transmission of vibration. When the equipment vibrates, the spring isolator 10 compresses and rebounds, converting the mechanical vibration into heat energy and dissipating it, thereby achieving the effect of vibration reduction. In this utility model, the spring isolator 10 is located in a suspended ZH spring isolator. The cooling component 8 includes a water storage tank 801, which is installed on one side of the top surface of the base 1. It can cool the drill bit 7 during the core extraction process, preventing the drill bit 7 from overheating and causing accelerated wear or affecting the core extraction quality. The top of the water storage tank 801 is connected to a water supply pipe 802. The water storage tank 801 is rectangular. The container is box-shaped. A water inlet is located at the top of the water storage tank 801. One end of a water pipe 802 is connected to the water inlet. The water pipe 802 consists of a C-shaped pipe and a straight pipe. The top surface of the C-shaped pipe is installed below two supports 9, which are bent right-angle rods. Two spring vibration isolators 10 are installed vertically at the bottom of the two supports 9. A drill bit 7 is located between the two supports 9. A row of nozzles 803 is connected to the water pipe 802. A row of through holes is opened at both opposite ends of the C-shaped pipe on the water pipe 802. The tops of several nozzles 803 are connected to... Connected to a row of through holes, water can be sprayed evenly onto the drill bit 7, providing all-around cooling and preventing the drill bit 7 from overheating, which could lead to accelerated wear, reduced hardness, or even damage. This ensures the service life and cutting performance of the drill bit 7, thereby improving the efficiency and quality of coring operations. It ensures that water can be sprayed onto the drill bit 7 from multiple directions and angles, achieving a highly efficient cooling effect and keeping the drill bit 7 in good working condition throughout the coring process. It also helps to promptly wash away rock cuttings generated during the coring process, preventing rock cuttings from accumulating around the drill bit 7 and affecting the continuation of the coring operation.
[0023] During operation, the automatic coring machine is moved to the coring position using the four movable wheels 2 on the top surface of the base 1. Through the sliding cooperation of the guide rail 4 and the slider 5, the driver 6 is controlled to move smoothly in the vertical direction, so that the drill bit 7 is lowered to the rock surface to start coring. Then, the driver 6 is started, so that it adjusts the output power and speed according to the rock hardness characteristics, driving the drill bit 7 to rotate. During the coring process, the water in the water tank 801 enters the water supply pipe 802 through the water supply hole, and then sprays the drill bit 7 from a row of nozzles 803 through the through holes at both ends of the "C" shaped pipe, cooling the drill bit 7 and washing away the rock cuttings. At the same time, the spring vibration isolator 10 at the bottom of the support 9 absorbs the vibration generated by the operation of the drill bit 7, preventing the vibration from affecting the stability of the equipment and the coring accuracy. The support rod 11 on the other side of the support column 3 shares the force of the drill bit 7, ensuring that the equipment operates reliably for a long time.
