Description

Technical Field

[0001] The invention relates to the technical field of ore sand drilling equipment, in particular to a sand ore drilling sampling device. Background Art

[0002] In the field of sand mining sampling, it is common practice to use specialized sampling equipment and techniques to extract representative samples from sand mines. These samples will be used to analyze the composition and quality of the ore sand. The sampling process needs to take into account accuracy and representativeness to ensure that the samples taken can truly reflect the characteristics of the entire ore body. Deep drilling is carried out using a drill rig to obtain ore sand samples from different depths. This method can provide continuous samples from the surface to the deep inside of the ore body, which helps to evaluate the vertical distribution of the ore body in detail.

[0003] Traditional drilling sand sampling methods often rely on more manual operations, such as manual drilling, sampling and sample processing. This not only increases the complexity of the operation, but also increases the labor intensity of the staff. At the same time, it faces the problem of inefficiency in the sampling process, especially in the environment of hard rock or complex geological structure, the sampling speed will be greatly reduced, and manual sampling is difficult to ensure that homogeneous and representative samples are obtained from each sampling point, which leads to deviations in sample data and affects the accuracy of the final analysis results. It usually lacks advanced stable control systems, which causes equipment failure or operational risks in complex or unstable terrain. Traditional sand sampling methods usually do not contain highly automated and intelligent elements, which limits their application in large-scale or continuous sampling operations.

[0015] Working principle: First, use the excavation mechanism to excavate a hole in the area where the excavation mechanism is needed to test the sand mine, then place the equipment in the hole, and lower the equipment by loosening the cable fixed on the magnetic suspension seat. The drill sleeve included in the excavation mechanism is inserted between the working barrel and the external sleeve. When the drill sleeve is driven to rotate, the excavation drill installed on the drill sleeve starts to rotate and break the soil and rock formation in the area to be tested. The excavated mineral material to be tested will penetrate into the working barrel along the excavation groove set by the excavation drill bit and the drill sleeve, and the excavation stabilization mechanism is activated. After the hydraulic drive assembly fixed at the bottom of the fixed ring is started, the traction ring fixed at its output end is pulled to slide upward along the side wall of the working barrel. At the same time, the traction ring slides and moves When the hydraulic drive component 1 is started, the hydraulic drive component 2 is also started, and the traction and drag ring 2 fixed at its output end is pulled upward along the side wall of the working cylinder. When the traction and drag ring 2 slides and moves, the three groups of linkage rods 2 installed on it are driven to move upward, and the other side end of the linkage rod 2 is rotatably installed in the middle part of the rotating rod 2, so that the three groups of linkage rods 2 are lifted up and rotated outward along the end of the fixed ring at the same time. The rubber pulleys installed at the outer ends of the three groups of rotating rods 1 contact the inner wall of the predetermined sampling slot at the same time, so as to stabilize in the drilling and excavation hole slot for sampling. When the hydraulic drive component 1 is started, the hydraulic drive component 2 is also started, and pulls the traction and drag ring 2 fixed at its output end to slide upward along the side wall of the working cylinder. When the traction and drag ring 2 slides and moves, it drives the three groups of linkage rods 2 installed on it to move upward, and the other side end of the linkage rod 2 is rotatably installed in the middle part of the rotating rod 2, so that the three groups of linkage rods 2 are lifted up and rotated outward along the end of the fixed ring at the same time. The three sets of rotating rods are lifted up and rotated outward along the ends of the connecting hinge seats at the same time, and the contact arc panels installed at the outer ends of the three sets of rotating rods simultaneously contact the inner wall of the predetermined sampling slot hole, thereby stabilizing the drilling and excavation hole slot for sampling. The sampling device is quickly fixed to the inner wall of the predetermined sampling slot hole in a triangular support manner. When it is necessary to sample slag and stones in a specific area, the motor arranged inside the motor box starts and drives the spiral conveying rod fixed at its output end to rotate inside the guide cylinder. The rotating spiral conveying rod forms an upward guiding suction force, which guides the samples to be taken in the sampling area into the working cylinder and the guide cylinder at the same time and gradually rises until it reaches the contact groove set on the side wall of the guide cylinder, and falls and gathers along the contact groove. In the aggregate pool, while the sand extraction mechanism is guiding the sampling, the impurity crushing mechanism is also activated. After the motor box 2 fixed to the bottom of the working cylinder by the bottom fixing ring 2 is started, it drives the crushing impeller 2 with its output shaft fixed to rotate along the bottom wall of the component cylinder. While the crushing impeller 2 rotates, its rotating shaft located in the component cylinder also drives the secondary bevel gear to rotate, and the secondary bevel gear then drives the auxiliary bevel gear meshing with it to rotate, and the auxiliary bevel gear guides the rotating torque to the main bevel gear meshing at the top again, so that the main bevel gear also rotates and rotates in the opposite direction to the secondary bevel gear, and the main bevel gear also guides a group of crushing impellers 1 with fixed rotating shafts to rotate along the top wall of the component cylinder, and the crushing impeller 1 and the secondary bevel gear form a rotating crushing ability in the opposite direction,The large-particle samples in the sampling are intensively crushed to reduce the possibility of the predetermined sampling slot being blocked by the accumulation of debris, and the sampling is completed smoothly; after the sampling is completed, the sampling equipment is pulled out of the predetermined sampling slot again through the cable on the magnetic suspension seat, and the sand extraction mechanism is activated at the same time. The start-up of the two sets of lifting motors drives a set of driving screws to rotate inside a set of extension boxes respectively, and the nut auxiliary block attached to the thread of the driving screw also drives the rotation of the screw and rises accordingly. The top fixing ring 2 fixed to the nut auxiliary block also drives the guide cylinder and the motor box 1 to rise, so that the motor box 1 slides upward on the inner wall of the working cylinder using the top fixing ring 1, and at the same time, the magnetic suspension seat that blocks the predetermined sampling slot is lifted and separated from the predetermined sampling slot. Through the opened magnetic suspension seat, the aggregate pool can be extended out of the working cylinder for sampling and recovery.

[0016] The present invention provides a sand mine drilling sampling device, which has the following beneficial effects: 1. The present invention has an efficient sampling and fixing mechanism: through the design of hydraulic drive components and multiple groups of linkage rods and rotating rods, the sampling device can be quickly positioned and fixed in the hole slot. This triangular support method not only improves the stability of the equipment, but also allows efficient sampling under complex or loose geological conditions. The entire sampling process has a high degree of automation, from drilling into the formation, fixing equipment, sampling to extracting samples, and then to sample processing and collection. The entire process does not require human intervention, which significantly improves work efficiency and safety. By using hydraulic drive components and mechanical linkage mechanisms, the entire sampling process is automated and mechanized, reducing the need for manual operation and potential errors, and improving work efficiency and safety.

[0017] 2. Impurity treatment and sample purification effects of the present invention: Utilizing the internal crushing mechanism, large particle impurities in the collected samples can be processed in real time, reducing the risk of blockage and equipment damage, while improving the purity and quality of the samples. The modular design of the system allows for rapid adjustment or replacement of the device in different sampling environments, improving the adaptability and versatility of the equipment.

[0018] 3. Stability and precise positioning effect of the present invention: Rubber pulleys, contact arc panels and other components are used to accurately position and stabilize the inside of the hole groove, ensuring that the sampling equipment can work stably in complex geological environments, thereby improving the accuracy and reliability of sampling. The design of the entire sampling equipment allows continuous operation, from excavation, sampling to sample processing and impurity separation, forming a complete operation chain, reducing the possibility of operation interruption and improving operation efficiency.
