[0001] This utility model relates to the field of sampling device technology, specifically to a rapid stratification sampling device for powdered materials. Background Technology

[0002] In industries such as metallurgy, chemicals, pharmaceuticals, and food, the quality of powdered materials is crucial, necessitating sampling and subsequent testing. Currently, most methods involve using forklifts or manual labor to move materials into piles and sample in sections and layers. This approach is inconvenient and results in significant waste of manpower and equipment costs. Furthermore, manual sampling is susceptible to sampling bias and subjective bias. Utility Model Content

[0003] This invention proposes a rapid stratified sampling device for powdered materials, which solves the problem of using forklifts or manual labor to transport materials and then sample them in sections and layers in related technologies. This is not only inconvenient for sampling, but also results in a significant waste of manpower and equipment costs. In addition, manual sampling is also easily affected by sampling deviations and subjective biases.

[0004] The technical solution of this utility model is as follows: A rapid stratification sampling device for powdery materials, the key feature of which is: comprising,

[0005] A sampling tube, one end of which is an open end for feeding, and the other end of which is a closed end. The sampling tube has sampling ports on its side wall, and there are multiple sampling ports, all of which are arranged along the length of the sampling tube.

[0006] An operating handle is provided around the sampling tube, and all the sampling ports are located between the open end of the sampling tube and the operating handle.

[0007] A transmission rod is rotatably disposed inside the sampling tube and is coaxially disposed with the sampling tube;

[0008] A helical blade is disposed on the transmission rod and near the open end of the sampling tube;

[0009] A rotary drive mechanism is connected to the end of the transmission rod away from the helical blade.

[0010] It also includes an inner rotating tube, which is located between the transmission rod and the sampling tube. The inner rotating tube is coaxially arranged with the transmission rod and fixedly connected. The outer wall of the inner rotating tube is in contact with the inner wall of the sampling tube. The side wall of the inner rotating tube has a material passage hole, which is arranged one-to-one with the sampling port. After the material passage hole and the sampling port are coaxial, it is used to take out the sample in the inner rotating tube.

[0011] The helical blades are located outside the inner rotating tube.

[0012] Both the material passage and the sampling port are elongated holes, with the length direction of the elongated holes being the same as the length direction of the sampling tube. The length of the sampling port is greater than the length of the material passage, and the width of the sampling port is greater than the width of the material passage.

[0013] The end of the spiral blade away from the rotary drive mechanism extends to the outside of the sampling tube.

[0014] The rotary drive mechanism is located outside the closed end of the sampling tube and is coaxially arranged with the transmission rod.

[0015] The end face of the open end of the sampling tube is beveled.

[0016] A scale line is provided on the outer wall of the sampling tube, and the scale line is arranged along the length direction of the sampling tube.

[0017] It also includes,

[0018] A support base is provided on the operating handle and located on the side of the operating handle away from the spiral blade; the rotary drive mechanism is provided on the support base and located on the side of the support base away from the operating handle.

[0019] A protective cover is provided on the support base and covers the periphery of the rotary drive mechanism.

[0020] It also includes a buffer layer disposed between the protective cover and the rotary drive mechanism.

[0021] The working principle and beneficial effects of this utility model are as follows: One end of the sampling tube is an open end for feeding, and the other end is a closed end. Multiple sampling ports are located on the side wall of the sampling tube, arranged along its length. An operating handle is located around the periphery of the sampling tube, with all sampling ports situated between the open end and the operating handle. A transmission rod is rotatably mounted inside the sampling tube and coaxially with it. Spiral blades are mounted on the transmission rod and positioned near the open end of the sampling tube. A rotary drive mechanism is connected to the end of the transmission rod furthest from the spiral blades. The operator holds the operating handle around the periphery of the sampling tube and uses the rotary drive mechanism to rotate the transmission rod, which in turn rotates the spiral blades. When the open end of the sampling tube is close to the pile of powdery material, the rotating spiral blades penetrate the powdery material like a drill. Material at different depths is continuously fed into the sampling tube under the pushing action of the spiral blades. By extracting material at different levels through the sampling ports, samples of different layers can be obtained, thus achieving the collection of powdery materials at different levels. With its simple structure and convenient operation, it can complete multi-layer sampling of powdery materials in a short time, improving work efficiency, reducing the labor intensity of operators, and minimizing waste of manpower and equipment costs. Furthermore, it reduces human intervention, is less susceptible to sampling bias and subjective bias, lowers sampling error, and increases sampling accuracy, ensuring that the samples are representative and providing a reliable basis for subsequent analysis and testing.

[0031] Example, refer to Figures 1-2 This invention provides a rapid stratification sampling device for powdered materials, comprising a sampling tube 1, an operating handle 2, a transmission rod 3, a spiral blade 4, and a rotary drive mechanism 5. One end of the sampling tube 1 is open for feeding, and the other end is closed. Multiple sampling ports 6 are located on the side wall of the sampling tube 1, arranged along its length. The operating handle 2 is positioned around the sampling tube 1, with all sampling ports 6 located between the open end of the sampling tube 1 and the operating handle 2. The transmission rod 3 is rotatably mounted inside the sampling tube 1 and coaxially aligned with it. The spiral blade 4 is mounted on the transmission rod 3 and close to the open end of the sampling tube 1. The rotary drive mechanism 5 is mounted on the sampling tube 1 and is connected to the end of the transmission rod 3 away from the spiral blade 4.

[0032] In this embodiment, the operator holds the operating handle 2 located around the sampling tube 1, allowing for convenient control of the entire device's position and angle. The rotary drive mechanism 5 provides power as needed, driving the transmission rod 3 to rotate, which in turn drives the spiral blades 4 to rotate. When the opening of the sampling tube 1 is close to the powdery material pile, the rotating spiral blades 4 penetrate the powdery material like a drill bit. Material at different depths is continuously transported into the sampling tube 1 under the pushing action of the spiral blades 4. Different layers of material are then extracted through the sampling port 6, thus obtaining samples from different layers and enabling the collection of powdery materials from different layers. The rotary drive mechanism 5 can control the drilling speed of the spiral blades 4 and the amount of material collected. By adjusting the insertion angle and depth of the sampling tube 1, combined with sampling ports 6 at different locations, targeted sampling can be performed on different parts and layers of the material pile. The rotary drive mechanism 5 and the sampling tube 1 are detachably connected, as are the transmission rod 3, facilitating disassembly and maintenance.

[0033] Compared to traditional methods of sampling by manually moving materials from piles using forklifts or by hand, this device directly drills into the material pile using the spiral blades 4, eliminating the need for large-scale material handling and greatly improving sampling convenience. Operators simply need to align the open end of the sampling tube 1 with the material pile and activate the rotary drive mechanism 5 to take a sample, reducing the tedious procedures and time consumption associated with material handling and lowering the workload for operators.

[0034] Traditional methods involve using forklifts and other machinery for material handling, as well as significant manual labor, resulting in high labor and equipment costs. This device, however, has a relatively simple structure, with operation primarily relying on a rotary drive mechanism 5 and a manually operated handle 2. This reduces reliance on large machinery, significantly lowering labor and equipment costs and saving overall expenses.

[0035] Traditional manual sampling is susceptible to sampling bias and subjective bias, resulting in samples that cannot accurately represent the overall characteristics of the material. This device automatically collects material at different depths using spiral blades 4 and performs layered sampling through multiple sampling ports 6 arranged along the length of the sampling tube 1. This method is less affected by sampling bias and subjective bias, enabling more scientific and accurate acquisition of material samples from different layers. It reduces the interference of human factors on sampling results, improves the accuracy and objectivity of sampling, and provides more reliable data support for subsequent material testing and quality analysis.

[0036] Furthermore, such as Figure 1 and Figure 2As shown, it also includes an inner rotating tube 7, which is located between the transmission rod 3 and the sampling tube 1. The inner rotating tube 7 and the transmission rod 3 are coaxially arranged and fixedly connected. The outer wall of the inner rotating tube 7 is in contact with the inner wall of the sampling tube 1. The side wall of the inner rotating tube 7 has a material passage hole 8, which is arranged in a one-to-one correspondence with the sampling port 6. After the material passage hole 8 and the sampling port 6 are coaxial, they are used to take out the sample in the inner rotating tube 7.

[0037] When the transmission rod 3 rotates, the inner rotating tube 7 rotates accordingly. During sampling, the material passage 8 separates from the sampling port 6. The sampling tube 1 can seal the material passage 8 on the inner rotating tube 7, allowing the material to remain in the inner rotating tube 7. After sampling, when the material needs to be removed, the inner rotating tube 7 is rotated to make the material passage 8 coaxially connected with the sampling port 6. The material can then be extracted in layers through the sampling port 6 and the material passage 8 to obtain the sample. This avoids accidental leakage or contamination of the sample during the sampling process. Simultaneously, the cooperative design of the inner rotating tube 7 and the sampling tube 1 allows the sample to be extracted more accurately from a specific position, corresponding to the sampling port 6, further ensuring the accuracy and representativeness of the sampling, and improving the flexibility and controllability of the sampling. The inner rotating tube 7 and the sampling tube 1 are detachably connected, facilitating disassembly and maintenance.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, the spiral blade 4 is located outside the inner rotating tube 7, which can better ensure the integrity of the sample inside the inner rotating tube 7.

[0039] Furthermore, such as Figure 1 and Figure 2 As shown, both the material passage 8 and the sampling port 6 are elongated holes, with their lengths aligned with the length of the sampling tube 1. The sampling port 6 is longer than the material passage 8, and its width is greater than that of the material passage 8. During sampling, as the inner rotating tube 7 rotates, the material passage 8 can move relative to the sampling port 6. When a sample needs to be retrieved, the rotation angle of the inner rotating tube 7 is precisely adjusted to ensure that the material passage 8 and the sampling port 6 are completely aligned or reach a suitable degree of alignment, ensuring smooth sample passage and increasing sampling accuracy and operability. The larger sampling port 6 provides more space for adjusting the material passage 8, and also facilitates observation and operation, improving sampling accuracy and success rate.

[0040] Furthermore, such as Figure 1 and Figure 2As shown, the end of the spiral blade 4 away from the rotation drive mechanism 5 extends to the outside of the sampling tube 1, which can better contact the material pile and more effectively roll the material into the sampling tube 1. Especially for some densely packed or non-flowing powdery materials, it can better achieve material collection, improve sampling efficiency and integrity, and enhance the ability to collect powdery materials.

[0041] Furthermore, such as Figure 1 and Figure 2 As shown, the rotary drive mechanism 5 is located outside the closed end of the sampling tube 1 and is coaxially arranged with the transmission rod 3. The output shaft of the rotary drive mechanism 5 is directly connected to the transmission rod 3, making power transmission more direct and stable, reducing energy loss and interference during transmission. At the same time, placing the rotary drive mechanism 5 outside the closed end of the sampling tube 1 helps protect the rotary drive mechanism 5 from material contamination and damage, extends the service life of the rotary drive mechanism 5, and facilitates maintenance and repair.

[0042] Furthermore, such as Figure 1 As shown, the end face of the open end of the sampling tube 1 is a bevel. When the sampling tube 1 is inserted into the pile of powdery materials, the bevel can play a certain guiding role, reduce the insertion resistance, make it easier for the sampling tube 1 to enter the material, reduce the operational difficulties caused by excessive resistance at the open end, improve work efficiency, and also reduce the wear on the sampling tube 1 and the spiral blade 4.

[0043] Furthermore, such as Figure 1 and Figure 2 As shown, scale lines 9 are provided on the outer wall of the sampling tube 1, arranged along the length of the sampling tube 1. Operators can visually understand the depth to which the sampling tube 1 is inserted into the material pile through the scale lines 9, thereby accurately controlling the sampling position and layer, ensuring that the sample accurately reflects the characteristics of different layers of the material pile. Simultaneously, it facilitates standardization and comparative analysis of multiple sampling operations, improving the reliability and repeatability of experimental data.

[0044] Furthermore, such as Figure 3As shown, the device also includes a support base 10 and a protective cover 11. The support base 10 is mounted on the operating handle 2 and located on the side of the operating handle 2 away from the spiral blade 4. The rotary drive mechanism 5 is mounted on the support base 10 and located on the side of the support base 10 away from the operating handle 2. The protective cover 11 is mounted on the support base 10 and covers the rotary drive mechanism 5. The support base 10 allows the rotary drive mechanism 5 to be properly mounted on the operating handle 2, ensuring stable operation of the rotary drive mechanism 5 when the operator operates the sampling tube 1, preventing shaking or displacement from affecting the sampling effect. It also facilitates the operator's grip and operation of the entire device, improving comfort and convenience. The protective cover 11 protects the rotary drive mechanism 5 from interference and damage from external factors such as dust and debris, extending its service life. It also provides safety for the operator, preventing accidental contact with rotating parts during operation and reducing safety risks, thus meeting the requirements of safe production.

[0045] Furthermore, such as Figure 3 As shown, it also includes a buffer layer 12, which is disposed between the protective cover 11 and the rotary drive mechanism 5. During the operation of the device, the buffer layer 12 can absorb and buffer the impact force generated by vibration or other external forces, reducing damage to the rotary drive mechanism 5. This improves the stability and durability of the device, protects the internal parts of the rotary drive mechanism 5 from damage, and extends the overall service life of the device. At the same time, it also helps to reduce the noise of the device during operation and improve the working environment.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
