Description

Technical Field

[0001] The utility model relates to the technical field of sampling tubes, in particular to a powder sampling tube with a layered sampling structure. Background Art

[0002] Powder sampling is a common operation in industry. The purpose is to take a representative sample from a large amount of powder materials for subsequent quality inspection, analysis or research. Powder sampling methods are divided into direct sampling method, quartering method, rotary sampling method and vibration sampling method. However, no matter which sampling method is adopted, it is necessary to ensure the representativeness of sampling, that is, the sample taken can reflect the average properties of the whole batch of powder.

[0003] The existing powder sampling tube is composed of a sampling tube body, a powder sampling component and a powder temporary storage cavity. A powder temporary storage cavity is reserved inside the sampling tube body, and a powder sampling component is installed on the upper side of the powder sampling tube. During use, the powder sample is taken and sent to the powder temporary storage cavity through the powder sampling component for temporary storage. However, this powder sampling tube cannot perform layered sampling on the powder, which will cause the obtained powder samples to be mixed in the powder temporary storage cavity, affecting the subsequent detection work of the powder sample. Content of the Utility Model

[0004] The purpose of the utility model is to provide a powder sampling tube with a layered sampling structure to solve the problem that the existing powder sampling tube cannot perform layered sampling on the powder, which will cause the obtained powder samples to be mixed in the powder temporary storage cavity as mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A powder sampling tube with a layered sampling structure, including a sampling tube body, a sampling port and a top plate.

[0006] Sampling ports are equidistantly arranged inside the sampling tube body. One end of a column is connected to the top of the sampling tube body, and the other end of the column is connected to the top plate.

[0007] Preferably, a layered sampling mechanism is arranged at the bottom of the top plate. The layered sampling mechanism is composed of an adjusting plate, a mounting rod, a reserved slot, a limiting plate, a connecting rod, a sealing plate and a plugging slot. The adjusting plate is arranged at the bottom of the top plate.

[0008] Preferably, the mounting rod is connected to the bottom of the adjusting plate. The outer side of the mounting rod is inserted into the sampling tube body, and the bottom of the sampling tube body is inserted into the reserved slot through the limiting plate.

[0009] Preferably, the sealing plate is connected to the outer side of the mounting rod through the connecting rod. The sealing plate is inserted into the sampling port, and the top of the sealing plate is inserted into the plugging slot opened inside the sampling tube body.

[0010] Preferably, a control box and a storage battery are installed inside the sampling tube body. A partition layer is provided inside the sampling tube body, and a vibration motor is installed inside the partition layer.

[0011] Preferably, a stable powder sampling mechanism is provided at the bottom of the top plate. The stable powder sampling mechanism consists of a guiding groove, an electric telescopic rod, a groove, a control button, and a return spring. The inside of the adjusting plate is inserted into the column through the guiding groove.

[0012] Preferably, the bottom of the adjusting plate is connected to the sampling tube body through an electric telescopic rod. A groove is formed at the top of the top plate, a control button is installed inside the groove, and a return spring is installed inside the reserved groove.

[0013] Compared with the prior art, the beneficial effect of the present utility model is as follows: for the powder sampling tube with a layered sampling structure, the sampling tube body is inserted into the powder to be sampled. While pushing the top plate downward, it is necessary to ensure that the position of the adjusting plate remains unchanged. After the sampling tube body is inserted to an appropriate depth, the adjusting plate is pulled upward. At this time, the adjusting plate drives the mounting rod to move upward, and at the same time, the sealing plate connected to the mounting rod through the connecting rod will move upward accordingly and be inserted into the insertion slot opened inside the sampling tube body, thereby opening the sampling port, solving the problem that the powder sampling tube cannot perform layered sampling on the powder, which will cause the obtained powder samples to be mixed in the powder temporary storage chamber.

[0014] 1. For the powder sampling tube with a layered sampling structure, to facilitate the accuracy of powder sample sampling and prevent the samples from mixing with each other, first insert the sampling tube body into the powder to be sampled. While pushing the top plate downward, it is necessary to ensure that the position of the adjusting plate remains unchanged. After the sampling tube body is inserted to an appropriate depth, the adjusting plate is pulled upward. At this time, the adjusting plate drives the mounting rod to move upward, and at the same time, the sealing plate connected to the mounting rod through the connecting rod will move upward accordingly and be inserted into the insertion slot opened inside the sampling tube body, thereby opening the sampling port. The vibration motor installed inside the partition layer is controlled by the control box to drive the powder near the sampling tube body to vibrate and loosen, and flow into the sampling chamber through the sampling port. The powder sampling tube with a layered sampling structure is provided with a layered sampling mechanism, which can complete layered rapid sampling and prevent sample mixing;

[0015] 2. For the powder sampling tube with a hierarchical sampling structure, in order to enable the sampling tube to perform stable sampling, an electric telescopic rod is used instead of manually lifting the adjustment plate. When sampling, press the control button inside the groove of the top plate to control the start of the electric telescopic rod. At this time, the electric telescopic rod opens upward and pushes the adjustment plate to move upward along the column through the guide groove, so that the sealing plate can be smoothly opened. At the same time, by controlling the opening and closing of the electric telescopic rod, the opening size of the sampling port can be adjusted to suit different sampling situations. The powder sampling tube with a hierarchical sampling structure can effectively control the flow rate and the amount of powder sampling by controlling the opening size of the sampling port through the electric telescopic rod.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a powder sampling tube with a hierarchical sampling structure, including a sampling tube body 1, a sampling port 2 and a top plate 3,

[0023] The inside of the sampling tube body 1 is equidistantly provided with sampling ports 2. The top of the sampling tube body 1 is connected to one end of a vertical column 101, and the other end of the vertical column 101 is connected to a top plate 3. A layered sampling mechanism 4 is arranged at the bottom of the top plate 3. The layered sampling mechanism 4 is composed of an adjusting plate 401, a mounting rod 402, a reserved slot 402a, a limiting plate 402b, a connecting rod 403, a sealing plate 404, and a plugging slot 405. The adjusting plate 401 is arranged at the bottom of the top plate 3;

[0024] The bottom of the adjusting plate 401 is connected to the mounting rod 402. The outer side of the mounting rod 402 is inserted into the sampling tube body 1. The bottom of the sampling tube body 1 is inserted into the reserved slot 402a through the limiting plate 402b. The outer side of the mounting rod 402 is connected to the sealing plate 404 through the connecting rod 403. The sealing plate 404 is inserted into the sampling port 2. The top of the sealing plate 404 is inserted into the plugging slot 405 opened inside the sampling tube body 1. A control box 5 and a storage battery 501 are installed inside the sampling tube body 1. A partition layer 6 is arranged inside the sampling tube body 1, and a vibration motor 601 is installed inside the partition layer 6.

[0025] During specific implementation, to facilitate the accuracy of powder sample sampling and prevent the samples from mixing with each other, first insert the sampling tube body 1 into the powder to be sampled. While pushing the top plate 3 downward, ensure that the position of the adjusting plate 401 remains unchanged. After inserting the sampling tube body 1 to an appropriate depth, pull the adjusting plate 401 upward. At this time, the adjusting plate 401 drives the mounting rod 402 to move upward. At the same time, the sealing plate 404 connected to the mounting rod 402 through the connecting rod 403 will move upward accordingly and be inserted into the plugging slot 405 opened inside the sampling tube body 1, thereby opening the sampling port 2. Then, control the start of the vibration motor 601 installed inside the partition layer 6 through the control box 5 to drive the powder near the sampling tube body 1 to vibrate and loosen, and the powder flows into the sampling chamber through the sampling port 2 to complete the layered sampling;

[0026] At the same time, the sampling chamber is an arc-shaped chamber, which can guide the outflow of the samples inside the sampling tube body 1 and avoid the samples from accumulating in the arc-shaped chamber. The bottom of the mounting rod 402 is connected with a limiting plate 402b, and the limiting plate 402b is located inside the reserved slot 402a, which can assist in limiting the movement of the mounting rod 402. This powder sampling tube with a layered sampling structure is provided with a layered sampling mechanism 4, which can complete layered and rapid sampling and prevent the samples from mixing.

[0027] Refer to Figure 1 and Figure 4It can be seen that a stable powder sampling mechanism 7 is provided at the bottom of the top plate 3. The stable powder sampling mechanism 7 is composed of a guide groove 701, an electric telescopic rod 702, a groove 703, a control button 704 and a return spring 705. The inside of the adjusting plate 401 is inserted into the column 101 through the guide groove 701. The bottom of the adjusting plate 401 is connected to the sampling tube body 1 through the electric telescopic rod 702. A groove 703 is formed at the top of the top plate 3. The control button 704 is installed inside the groove 703. The return spring 705 is installed inside the reserved groove 402a.

[0028] During specific implementation, in order to enable the sampling tube to perform stable sampling, the electric telescopic rod 702 is used to replace manual lifting of the adjusting plate 401. When sampling, press the control button 704 inside the groove 703 of the top plate 3 to control the start of the electric telescopic rod 702. At this time, the electric telescopic rod 702 opens upward and pushes the adjusting plate 401 to move upward along the column 101 through the guide groove 701, and the sealing plate 404 can be smoothly opened. At the same time, by controlling the opening and closing of the electric telescopic rod 702, the opening size of the sampling port 2 can be adjusted to be suitable for different sampling situations. At the same time, the return spring 705 installed in the reserved groove 402a can assist the adjusting plate 401, the mounting rod 402, the limiting plate 402b, the connecting rod 403 and the sealing plate 404 to reset. The operation is stable. The powder sampling tube with a layered sampling structure can effectively control the powder sampling flow rate and the sampling amount by controlling the opening size of the sampling port 2 through the electric telescopic rod 702.

[0029] In summary, when using the powder sampling tube with a layered sampling structure, first insert the sampling tube body 1 into the powder to be sampled, and start the electric telescopic rod 702. At this time, the electric telescopic rod 702 opens upward and pushes the adjusting plate 401 to move upward along the column 101 through the guide groove 701, and the sealing plate 404 can be smoothly opened. Start the vibration motor 601 installed in the partition layer 6 through the control box 5 to drive the powder near the sampling tube body 1 to vibrate and loosen, and it can flow into the sampling chamber through the sampling port 2. Among them, the storage battery 501 is used to provide power for the electric telescopic rod 702, the control box 5 and the vibration motor 601.
