[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0027] In order to make the above-mentioned purposes, characteristics and advantages of the present application more apparent, obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0028] In the calcium carbonate related industry, from ore mining to processing to final product manufacturing, the quality control of calcium carbonate raw materials is extremely critical. Among them, accurately understanding the composition, particle size and other characteristics of calcium carbonate pile at different depths is crucial for optimizing the production process and ensuring product quality. A device that can effectively detect and sample different depths of calcium carbonate pile has become an urgent need for industry development.

[0029] The structure of this detection and sampling device is delicate and complex, and each part works together to achieve accurate sampling of calcium carbonate piles at different depths. The main frame is made of high-strength, corrosion-resistant alloy material, ensuring that it remains stable in structure even in harsh industrial environments and frequent deep calcium carbonate pile operations, providing a solid foundation for reliable operation of the entire device. At the front end of the frame, a telescopic sampling rod is connected. The sampling rod is composed of multiple nested sections and can be flexibly adjusted in length according to actual needs to meet the sampling requirements of calcium carbonate piles at different depths. For example, when facing a shallow calcium carbonate pile, the sampling rod can be retracted to a shorter length for operation; when sampling a deep calcium carbonate pile, the sampling rod can be gradually extended to the specified depth.

[0030] At the end of the sampling rod, the core sampling component, the sampling drill bit, is installed. This drill bit is made of special hard alloy material, with extremely high hardness and wear resistance, capable of easily penetrating the hard surface of the calcium carbonate pile. The shape of the drill bit is carefully designed to be spiral, and during the rotary drilling process, the spiral structure can continuously draw the surrounding calcium carbonate powder into the sampling cavity inside the drill bit. The sampling cavity has a specific capacity and is equipped with a sealing device to ensure that the collected calcium carbonate sample does not leak during sampling, while also preventing external impurities from mixing in, ensuring the purity and representativeness of the sample.

[0031] To drive the sampling rod and drill bit, the device is equipped with a set of power system. The power system is mainly composed of motor and reduction gear. The motor provides powerful power output, through the reduction gear, the high-speed rotation of the motor is converted into low-speed large torque output suitable for sampling operation, so as to drive the sampling rod to rotate stably, and push the drill bit to drill into the calcium carbonate pile with appropriate force and speed. The reduction gear also plays a role in protecting the motor, avoiding damage to the motor under overload conditions, prolonging the service life of the equipment.

[0032] In the process of sampling in the calcium carbonate pile, in order to monitor the depth and position of sampling in real time, the device integrates an advanced positioning and depth measurement system. This system uses high-precision sensors such as laser ranging sensors and inclination sensors to accurately measure the extension length of the sampling rod and the angle with the vertical direction, and calculates the actual depth and spatial position of the sampling drill bit in the calcium carbonate pile through complex algorithms. These data will be fed back to the operation panel in real time, and the operator can accurately control the depth and position of sampling according to the displayed information, ensuring that the collected samples are representative.

[0033] In practical application scenarios, this detection sampling device shows significant advantages. In calcium carbonate ore mining sites, it can sample and analyze different depth layers of ore, help mining personnel understand the composition distribution of ore, reasonably plan the mining scheme, and improve the mining efficiency and utilization rate of ore. In calcium carbonate processing enterprises, by sampling and detecting different depths of raw material pile, the quality change of raw material can be grasped in time, and the processing process parameters can be adjusted to ensure the stability of product quality. For example, when detecting that the particle size of deep calcium carbonate raw material is large, the enterprise can appropriately increase the intensity of the crushing process in the processing process to ensure that the particle size of the final product meets the standard.

[0034] Compared with traditional sampling methods, this device has many obvious improvements. Traditional sampling methods often rely on manual operation, which not only has high labor intensity and low efficiency, but also due to the subjectivity and limitations of manual operation, it is difficult to ensure the accuracy and representativeness of sampling. This detection sampling device realizes automatic operation, greatly reducing the work burden of the operator, and improving the accuracy and efficiency of sampling. Its precise positioning and depth measurement function makes the collected samples truly reflect the characteristics of different depths of calcium carbonate pile, providing a reliable data basis for subsequent detection and analysis.

[0035] However, the device also faces some challenges in development and application. On the one hand, due to the need to penetrate different depths of calcium carbonate pile, the device will be subjected to greater resistance and wear during operation, which puts high requirements on the durability of the equipment. Although high-strength materials and advanced manufacturing processes are currently used, component wear and damage may still occur after long-term frequent use, requiring regular maintenance and replacement, increasing the cost and difficulty of use. On the other hand, for some special properties of calcium carbonate pile, such as calcium carbonate pile containing a large amount of impurities or having viscosity, the sampling process may be hindered, affecting the sampling effect. For example, calcium carbonate with strong viscosity may adhere to the sampling drill bit, causing the sampling chamber to be blocked and unable to normally collect samples.

[0036] Looking to the future, with the continuous progress of science and technology, this detection and sampling device is expected to make greater breakthroughs and developments. In terms of material research and development, new high-strength, wear-resistant, corrosion-resistant materials will be continuously explored and applied to further improve the durability and reliability of the device and reduce maintenance costs. In terms of technological innovation, more advanced sensing technology and automation control technology may be introduced to achieve more intelligent sampling operations. For example, through artificial intelligence algorithms, sampling parameters can be automatically adjusted according to the real-time situation of the calcium carbonate pile to improve the adaptability and accuracy of sampling. In terms of application expansion, in addition to playing a greater role in the existing calcium carbonate industry, it may also be applied in other similar mineral resource exploitation and industrial raw material detection fields to provide more powerful technical support for the development of related industries and promote the entire industry to develop in a more efficient and precise direction.
