Description

Technical Field

[0001] This application belongs to the field of nickel ore sampling technology, specifically a rapid sampler for the surface layer of laterite nickel ore. Background Technology

[0002] Lateritic nickel ore is a nickel deposit formed by long-term weathering, leaching, and deposition of ultrabasic rocks in tropical or subtropical climates. It mainly contains nickel hydroxide and iron oxides. Because it contains iron oxides, it is mostly reddish-brown and is an important raw material for nickel extraction. Surface sampling is used to preliminarily assess the economic value of the resources, analyze the grade and distribution of elements such as nickel and iron, understand the mineral composition to determine the smelting process, refer to the physical properties of the surface ore to assist in mining planning, monitor harmful elements such as heavy metals in the environment, and track the weathering and quality changes of the deposit. The surface sampling depth is usually 0.2-0.5 meters. Common sampling methods include spiral sampler sampling, which uses a high-strength, corrosion-resistant metal spiral drill rod to rotate and drill into the ore layer to collect samples.

[0003] When sampling loose mineral layers such as laterite nickel ore, existing spiral samplers rely mainly on operators holding the sampler with both hands and applying pressure to drive it to rotate and drill into the mineral layer. Due to the lack of external support structure, the sampler is prone to tilting or deviating when encountering complex situations such as uneven mineral layer hardness. This not only makes it difficult to accurately control the sampling depth, but also causes the obtained sample to deviate from the target layer, resulting in a decrease in sample representativeness. At the same time, the uneven force on the spiral blades in the tilted state exacerbates equipment wear and reduces service life. Therefore, a rapid sampler for the surface layer of laterite nickel ore is provided. Utility Model Content

[0004] The purpose of this application is to provide a rapid sampler for the surface layer of laterite nickel ore in order to solve the problems mentioned above.

[0005] The technical solution adopted in this application is as follows: a rapid sampler for the surface of laterite nickel ore, including a sampling tube, a sealing top cover fixedly installed at the top of the sampling tube by a set bolt, a spiral sampling rod provided inside the sampling tube, and a driving mechanism connected to the spiral sampling rod provided on the top surface of the sealing top cover.

[0006] A connecting ring is provided on the outer surface of the sampling tube near the bottom end. Two sliding grooves are symmetrically opened on the outer surface of the sampling tube, and sliding blocks are slidably connected inside the two sliding grooves. A spring rod is fixedly installed on the top surface of the inner side of the sliding groove. The bottom end of the spring rod is fixed to the top surface of the sliding block.

[0007] In a preferred embodiment, the drive mechanism includes a handheld electric drill, a spline connecting shaft, and a spline connecting groove. The handheld electric drill is fixedly installed on the top surface of the sealing top cover. The spline connecting shaft is fixedly installed on the drive end of the handheld electric drill. The top surface of the spiral sampling rod has a spline connecting groove corresponding to the spline connecting shaft. The spline connecting shaft is inserted into the inside of the spline connecting groove.

[0008] In a preferred embodiment, a discharge pipe is fixedly installed on the outer surface of the sampling cylinder, and a sampling collection bucket is threadedly connected to the end of the discharge pipe away from the sampling cylinder.

[0009] In a preferred embodiment, a connecting tube is provided at the bottom end of the sampling tube, and multiple breaking teeth are installed in a circumferential array on the bottom surface of the connecting tube. A fixing rod is symmetrically fixedly installed near the outer surface of the bottom end of the spiral sampling rod, and one end of the fixing rod is fixed to the inner wall surface of the connecting tube.

[0010] In a preferred embodiment, an installation ring is fixedly installed on the inner wall of the sampling cylinder, a bearing seat is fixedly installed on the top surface of the installation ring, and the spiral sampling rod is fixedly installed in the middle of the bearing seat near the outer surface of the top end.

[0011] In a preferred embodiment, the sampling collection bucket is made of transparent acrylic material, and the outer surface of the sampling collection bucket is fixedly equipped with a scale.

[0015] 1. In this application, due to the adoption of the above-mentioned scheme, the operator presses down on the sampling cylinder to push it downwards. The crushed ore is continuously conveyed upwards along the inner wall of the sampling cylinder under the action of the spiral blades. During this process, the connecting ring compresses the spring rod, which can adaptively extend and retract according to the ore resistance. When the predetermined sampling depth is reached, the operator can install the threaded sampling collection bucket at the end of the discharge pipe. The transparent and graduated sampling collection bucket allows the operator to observe the sampling volume in real time. After the sample collection is completed, the electric drill is turned off, and the sampling collection bucket is unscrewed to obtain a complete sample. The device can form a support structure through the connecting ring, sliding block, spring rod, support rod and support ring, which can minimize the tilting and tipping of the sampler. Through the cooperation of the drive mechanism and the spiral sampling rod, the effects of stable transmission, efficient ore conveying and accurate collection are achieved.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] refer to Figures 1-5As shown, a rapid surface sampler for laterite nickel ore includes a sampling cylinder 1. A sealing top cover 2 is fixedly installed at the top of the sampling cylinder 1 by bolts. A spiral sampling rod 3 is installed inside the sampling cylinder 1. An installation ring 16 is fixedly installed on the inner wall of the sampling cylinder 1. A bearing seat 17 is fixedly installed on the top surface of the installation ring 16. The spiral sampling rod 3 is fixedly installed in the middle of the bearing seat 17 near the outer surface of the top end. A connecting cylinder 13 is provided at the bottom end of the sampling cylinder 1. Multiple breaking teeth 14 are installed in a circumferential array on the bottom surface of the connecting cylinder 13. The spiral sampling rod 3 is symmetrically fixed near the outer surface of the bottom end. A fixing rod 15 is installed, with one end of the fixing rod 15 fixed to the inner wall of the connecting cylinder 13. The bearing seat 17 and the spiral sampling rod 3 are matched to effectively reduce the frictional resistance of the spiral sampling rod 3 during rotation, ensuring its stable rotation. The connecting cylinder 13 and the crushing teeth 14 at its bottom can crush the hard lumps on the surface of laterite nickel ore, significantly improving the sampling efficiency. The fixing rod 15 makes it easy to firmly connect the spiral sampling rod 3 and the connecting cylinder 13, ensuring that the two rotate synchronously during operation and avoiding structural damage due to uneven force.

[0024] refer to Figures 1-5 As shown, the top surface of the sealed top cover 2 is provided with a drive mechanism 4 connected to the spiral sampling rod 3. The drive mechanism 4 includes a handheld electric drill 401, a spline connecting shaft 402, and a spline connecting groove 403. The handheld electric drill 401 is fixedly installed through the top surface of the sealed top cover 2. The spline connecting shaft 402 is fixedly installed at the drive end of the handheld electric drill 401. The top surface of the spiral sampling rod 3 is provided with a spline connecting groove 403 corresponding to the spline connecting shaft 402. The spline connecting shaft 402 is inserted into the inside of the spline connecting groove 403. Through the spline connection method, torque can be transmitted efficiently, preventing slippage during power transmission and ensuring that the spiral sampling rod 3 obtains a stable driving force. With the handheld electric drill 401 as the power source, there is no need to rely on an external power source, which is convenient for flexible operation in complex environments such as the field. At the same time, the detachable spline structure facilitates the later maintenance and replacement of parts. The handheld electric drill 401 is an existing structure and a common handheld electric drill on the market, which can be directly purchased and will not be described in detail.

[0025] refer to Figures 1-5As shown, a connecting ring 5 is provided on the outer surface of the sampling cylinder 1 near the bottom. Two symmetrical grooves 6 are opened on the outer surface of the sampling cylinder 1, and sliding blocks 7 are slidably connected inside the two grooves 6. An arc-shaped push plate 18 is fixedly installed on the bottom surface of the sliding block 7, and a spring rod 8 is fixedly installed on the top surface of the inner side of the groove 6. The bottom end of the spring rod 8 is fixed to the top surface of the sliding block 7, and one end of the sliding block 7 is fixed to the inner wall surface of the connecting ring 5. The spring rod 8 can effectively buffer vibration during the sampling process, reduce the shaking of the equipment caused by uneven force, and reduce the risk of component damage. The sliding block 7 can facilitate the reset of the connecting ring 5 and the up and down movement of the arc-shaped push plate 18, and push out the debris inside the groove 6 to prevent the debris from accumulating and clogging the groove 6. By setting the symmetrically distributed grooves 6 and sliding blocks 7, the force of the subsequent sampler can be balanced during operation, further enhancing the stability of the sampling process.

[0026] refer to Figures 1-5 As shown, a support rod 9 is fixedly installed on the bottom surface of the connecting ring 5. Multiple support rods 9 are installed in a circular array on the bottom surface of the connecting ring 5, and all support rods 9 are made of high-strength metal material. A support ring 10 is fixedly installed at the bottom end of each support rod 9. The multiple support rods 9 and support rings 10 can form a stable support structure, which can effectively prevent the sampler from tilting during the subsequent rotation sampling process. The high-strength metal support rods 9 can improve the deformation resistance and are suitable for sampling work under different geological conditions. The support rings 10 increase the contact area with the ground, reduce the pressure of the sampler on the ground, and prevent it from sinking into soft mineral layers.

[0027] refer to Figures 1-5 As shown, a discharge pipe 11 is fixedly installed on the outer surface of the sampling cylinder 1. A sampling collection bucket 12 is threadedly connected to the end of the discharge pipe 11 away from the sampling cylinder 1. The sampling collection bucket 12 is made of transparent acrylic material, and a scale is fixedly installed on the outer surface of the sampling collection bucket 12. The threaded connection of the sampling collection bucket 12 facilitates quick disassembly and cleaning, effectively avoiding cross-contamination between different samples. The transparent acrylic material allows operators to intuitively observe the sample collection situation and monitor the sampling progress in real time. The scale on the bucket can accurately measure the sample volume, providing convenience for subsequent mineral composition analysis and reducing additional measurement procedures.

[0028] The implementation principle of this application's embodiment of a rapid surface sampler for laterite nickel ore is as follows: During use, the operator places the sampler at the target sampling point. At this time, the support ring 10 is in close contact with the ground, forming a stable support structure to ensure the sampler's vertical stability. Then, the operator starts a handheld electric drill 401, which connects to the splined connecting groove 403 of the spiral sampling rod 3 via the splined connecting shaft 402, achieving efficient torque transmission and driving the spiral sampling rod 3 to rotate. Simultaneously, the crushing teeth 14 at the bottom of the connecting cylinder 13 simultaneously crush the surface ore. Then, the operator presses down on the sampling cylinder 1 to push it downwards. The crushed ore is continuously conveyed upwards along the inner wall of the sampling cylinder 1 under the action of the spiral blades. During this process, the connecting ring 5 compresses the spring rod 8. The device adapts to the resistance of the ore and expands automatically. When the predetermined sampling depth is reached, the threaded sampling collection bucket 12 can be installed at the end of the discharge pipe 11. The transparent and graduated sampling collection bucket 12 allows the operator to observe the sampling volume in real time. After the sample is collected, the electric drill is turned off, and the sampling collection bucket 12 can be unscrewed to obtain a complete sample. The device can form a support structure through the connecting ring 5, sliding block 7, spring rod 8, support rod 9 and support ring 10, which can minimize the tilting and tipping of the sampler. Through the cooperation of the drive mechanism 4 and the spiral sampling rod 3, stable transmission, efficient ore conveying and accurate collection are achieved, realizing the rapid, stable and accurate collection of surface samples of laterite nickel ore.
