Description

TECHNICAL FIELD

[0001] The present scheme belongs to the technical field of geological exploration detection, and particularly relates to a geological core splitting machine. BACKGROUND

[0002] In the geological field, the cylindrical rock sample drilled by using a ring-shaped drill bit and other coring tools is called a core; the core is important physical geological data for studying and understanding the underground geology and mineral conditions; in geological mineral exploration, when the core is analyzed and studied, it is usually split into two halves, one half is used for sampling and testing to understand and analyze the geological conditions, and the other half is stored for sample preservation, so the core splitting machine is used for use.

[0003] At present, the existing geological exploration core splitting machine with the publication number CN114486446A includes an operation table, a guide plate is fixedly installed inside the operation table, two moving plates are interactively connected to the surface of the guide plate, a fixed assembly is arranged on one side of each of the two moving plates, a lead screw is rotationally connected inside the operation table, and the thread rotation directions of the lead screw at both ends are opposite; the present application has the advantages of being convenient for fixing the two ends of the core, avoiding the phenomenon of splashing of the core during splitting, and ensuring the personal safety of the workers; the core splitting machine can be used for splitting cores of different lengths, and is more convenient to use and operate.

[0004] However, there is a problem that debris may fly out during splitting, which may easily injure people. CONTENT OF THE INVENTION

[0005] The present scheme provides a geological core splitting machine to solve the problem that debris may fly out during splitting, which may easily injure people.

[0006] The present scheme provides a geological core splitting machine, which includes:

[0007] a base;

[0008] a driving system for driving the splitting knife to move;

[0009] a splitting knife, which is slidingly connected with the base;

[0010] a fixing mechanism for fixing the sample, which cooperates with the base;

[0011] a protective plate, which is fixedly connected with the base and cooperates with the splitting knife.

[0012] The principle of the present scheme is that the base provides a foundation support structure for the entire device, providing mounting locations and necessary stability for other components. The drive system is responsible for powering the sample splitting knife, enabling it to move along a predetermined track to complete the cutting operation. The sample splitting knife is slidingly connected to the base and is driven by the drive system to accurately cut the core sample fixed on the fixing mechanism. The fixing mechanism is used to firmly hold the core sample, ensuring that the sample does not shift or rotate during cutting, thereby ensuring the flatness and accuracy of the cutting surface. The protective plate is fixedly connected to the base. Its main function is to protect the safety of the operator.

[0013] The beneficial effects of the present scheme are that the protective plate avoids the splashing of debris that may occur during cutting, causing injury, and effectively prevents the spread of dust generated during cutting, keeping the working environment clean.

[0014] Further, the drive system includes a hydraulic cylinder and a hydraulic pump, the hydraulic cylinder includes a cylinder body, a piston and a connecting rod, the cylinder body is fixedly connected with the base, the piston is slidingly and sealingly connected with the cylinder body, the hydraulic pump is in communication with the cylinder body, one end of the connecting rod is fixedly connected with the piston, and the other end is fixedly connected with the sample splitting knife.

[0015] When the sample splitting knife needs to move, the hydraulic pump is started, causing oil to enter the cylinder body, pushing the piston to move, which in turn drives the connecting rod to move, and the connecting rod drives the sample splitting knife to move. The hydraulic system can provide very smooth and fine control, so that the sample splitting knife can accurately cut according to the preset path, improving the cutting accuracy.

[0016] Further, it further includes a sliding block and a guide rail, the guide rail is fixedly connected with the base, the cylinder body of the hydraulic cylinder and the hydraulic pump are fixedly connected with the guide rail, the sliding block is slidingly connected with the guide rail, and the sample splitting knife is fixedly connected with the sliding block.

[0017] The sliding block can smoothly slide back and forth on the guide rail, providing accurate guidance for the sample splitting knife. In this way, during cutting, the sample splitting knife can move along the preset straight line path, avoiding deviation or shaking. By using the combination of sliding block and guide rail, the movement path of the sample splitting knife is well controlled, significantly improving the flatness and accuracy of the cutting surface, which is helpful for subsequent geological analysis work.

[0018] Further, the fixing mechanism includes a fixed plate and a spring, one end of the spring is fixedly connected with the protective plate, and the other end is fixedly connected with the fixed plate, the fixed plate cooperates with the sample, and the fixed plate is slidingly connected with the base.

[0019] The fixed plate is directly in contact with the sample and is responsible for physically clamping the core sample. The fixed plate is slidingly connected to the base to accommodate different sizes of samples. One end of the spring is fixedly connected to the protective plate, and the other end is fixedly connected to the fixed plate. The presence of the spring provides elastic support force for the fixed plate, allowing the fixed plate to automatically adjust its position according to the actual size of the sample and apply appropriate pressure to ensure the sample is stable and does not shift.

[0020] The elasticity of the spring and the sliding characteristics of the fixed plate make this design adaptable to core samples of different sizes and shapes without the need for frequent replacement or adjustment of the clamp, improving the versatility and efficiency of the equipment.

[0021] Further, it further includes an adjusting mechanism, which includes a steel cable, a first pulley and a second pulley, the first pulley is rotatably connected with the cylinder body, the second pulley is rotatably connected with the protective plate, one end of the steel cable is fixedly connected with the piston, and the other end is fixedly connected with the fixed plate through the first pulley and the second pulley.

[0022] When the sample splitting knife is retracted, the hydraulic pump is started to extract the oil in the cylinder, causing the piston to retract, which in turn causes the sample splitting knife to retract. When the piston retracts, it pulls the steel cable, which pulls the fixed plate through the first pulley and the second pulley, causing the spring to compress, making it easier for the operator to place the sample on the base.

[0023] When the sample needs to be split, the operator only needs to start the hydraulic pump to pump oil into the cylinder, causing the piston to extend. At this time, under the action of the spring, the fixed plate will automatically reset and clamp.

[0024] This mechanism achieves the effect of automatically opening the fixed mechanism when not splitting the sample and automatically clamping the sample when splitting the sample through the adjusting mechanism. This reduces the number of steps and improves efficiency.

[0025] Further, it further includes a controller and a start-stop switch, the controller is electrically connected with the hydraulic pump, and the start-stop switch is electrically connected with the controller. The start-stop switch usually also includes the function of an emergency stop button. Once an abnormal situation occurs (such as sample rupture, equipment failure, etc.), the operator can immediately press the button to stop the equipment from running, effectively preventing accidents and protecting the safety of personnel and equipment.

[0026] Further, it further includes a handle, the handle is fixedly connected with the guide rail. When it is necessary to adjust the position of the entire device or move the parts during maintenance, the handle provides a convenient operating point. The user can easily push and pull the device or its components by holding the handle, improving the convenience of operation. BRIEF DESCRIPTION OF DRAWINGS
