Description

Technical Field

[0001] This utility model belongs to the field of powder sampling technology, specifically a powder sampler. Background Technology

[0002] In numerous industrial sectors, such as chemical, pharmaceutical, and food processing, the handling of powdered materials is extremely common. In chemical production, accurate sampling is essential for the quality inspection and process monitoring of various powdered raw materials (such as catalyst powders and chemical additive powders). The pharmaceutical industry has even stricter requirements for sampling powdered pharmaceutical raw materials (such as drug powders and excipient powders), as this relates to the consistency and safety of drug quality. In food processing, powdered products such as flour, sugar powder, and milk powder require appropriate sampling at every stage from raw materials to finished products to ensure quality. The handling of large quantities of powdered materials in these industries necessitates sampling that can represent the overall characteristics of the material, which has driven the development of powder sampler technology.

[0003] Traditional powder sampling methods have many problems. Manual scooping is one of the most primitive methods, but this method is highly prone to error. For example, operators cannot guarantee consistency in the depth, location, and quantity of each scoop, which can easily lead to samples that do not reflect the true properties of the overall material. For unevenly distributed powders, such as chemical powders containing agglomerated particles or food powders with different particle size distributions, manual scooping may only collect one type of particle, causing bias in the results.

[0004] Therefore, this utility model provides a powder sampler. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A powder sampler of this utility model includes a drill bit; multiple support rods are fixedly connected to the top of the drill bit; threaded rods are fixedly connected to the tops of the multiple support rods; one end of each support rod is connected to the top of the drill bit and the other end is connected to the bottom of the threaded rod; a hollow tube is fixedly connected to the top of the threaded rod; the bottom of the hollow tube communicates with the threaded rod. This device can achieve consistency in the depth, position, and quantity of powder sampling each time, thereby reducing uneven powder sampling and preventing the sample from failing to reflect the true properties of the overall material.

[0007] Preferably, a circular column is fixedly connected to the top of the threaded rod; the circular column is located in the middle of the hollow tube; and multiple stirring blades are fixedly connected to the outside of the circular column. When the powder is collected inside the hollow tube, the stirring blades on the outer wall of the circular column can rotate to stir the powder, thereby ensuring uniform powder distribution and improving the representativeness of the sample.

[0008] Preferably, a top block is fixed to the top of the circular column; a sealing gasket is provided on the outer wall of the top block; the sealing gasket is located at the bottom of the outer wall of the top block and connected to the hollow tube; multiple screws are fixed to the top of the sealing gasket. This device can effectively prevent powder leakage during the sampling process, avoiding environmental pollution, material loss, and health hazards to operators caused by powder leakage.

[0009] Preferably, a telescopic rod is fixedly connected to the top of the top block; a circular rod is fixedly connected to the inner wall of the telescopic rod; and a handrail is fixedly connected to the top of the circular rod. When it is necessary to sample powder at different depths, the length of the telescopic rod can be flexibly adjusted within a large range according to the actual sampling needs through its compression function, thereby enabling sampling at different depths and improving the convenience and accuracy of sampling.

[0010] Preferably, a motor is mounted on the top of the drill bit; the motor is located near the center of the top of the drill bit; the top of the motor is connected to a threaded rod. By rotating the threaded rod, the drill bit can quickly cut into and collect the powder, greatly shortening the sampling time, and significantly improving work efficiency, especially when a large amount of powder needs to be sampled.

[0011] Preferably, an elastic cloth is fixed to the outer wall of the telescopic rod; the bottom of the elastic cloth is connected to the handrail; and the elastic cloth is wrapped around the middle of the telescopic rod. This arrangement can reduce the problem of powder falling into the middle of the telescopic rod during the sampling process, thus reducing the impact on the telescopic rod's extension and retraction, and improving the stability of the telescopic rod at the bottom of the circular rod.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The powder sampler described in this utility model can achieve consistency in the depth, position and quantity of powder sampling each time through the threaded rod, thereby reducing uneven powder sampling and preventing the sample from failing to reflect the true properties of the overall material.

[0014] 2. The powder sampler described in this utility model can effectively prevent powder leakage during the sampling process through a sealing gasket, thus avoiding environmental pollution, material loss, and harm to the health of operators caused by powder leakage. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 2 As shown in the embodiment of this utility model, a powder sampler includes a drill bit 1; a plurality of support rods 11 are fixedly connected to the top of the drill bit 1; threaded rods 12 are fixedly connected to the top of the plurality of support rods 11; one end of each support rod 11 is connected to the top of the drill bit 1 and the other end is connected to the bottom of the threaded rod 12; a hollow tube 13 is fixedly connected to the top of the threaded rod 12; the bottom of the hollow tube 13 communicates with the threaded rod 12. During operation, the device is first placed in the powder to be sampled. At this time, the top of the drill bit 1 contacts the powder. Then, by controlling the rotation of the threaded rod 12, the powder is collected from the outer wall of the threaded rod 12 into the interior of the hollow tube 13. This device ensures consistency in the depth, position, and quantity of powder sampling each time, thereby reducing uneven powder sampling and preventing the sample from failing to reflect the true properties of the overall material.

[0024] like Figure 2 As shown, a circular column 2 is fixedly connected to the top of the threaded rod 12; the circular column 2 is located in the middle of the hollow tube 13; and multiple stirring blades 21 are fixedly connected to the outside of the circular column 2. When the powder is collected inside the hollow tube 13, the stirring blades 21 set on the outer wall of the circular column 2 can rotate to stir the powder. This arrangement can make the powder evenly distributed and improve the representativeness of the sample.

[0025] like Figure 3As shown, a top block 3 is fixedly connected to the top of the circular column 2; a sealing gasket 31 is provided on the outer wall of the top block 3; the sealing gasket 31 is located at the bottom of the outer wall of the top block 3 and connected to the hollow tube 13; multiple screws 32 are fixedly connected to the top of the sealing gasket 31. Before the sampling operation begins, the sealing gasket 31 is connected to the inner wall of the hollow tube 13 through the screws 32, and the sealing gasket 31 is fully compressed by tightening the screws 32 to achieve a good sealing effect. This device can effectively prevent powder leakage during the sampling process, avoiding environmental pollution, material loss, and health hazards to operators caused by powder leakage.

[0026] like Figures 3 to 4 As shown, a telescopic rod 4 is fixedly connected to the top of the top block 3; a circular rod 41 is fixedly connected to the inner wall of the telescopic rod 4; and a handrail 42 is fixedly connected to the top of the circular rod 41. When it is necessary to sample powder at different depths, the telescopic rod 4 can be extended or retracted towards the drill bit 1 to allow the threaded rod 12 to reach the required depth. Then, the telescopic rod 4 can be stopped extending or retracting to perform sampling. The compression function of the telescopic rod 4 allows its length to be flexibly adjusted within a large range according to actual sampling needs, enabling sampling at different depths and improving the convenience and accuracy of sampling.

[0027] like Figure 5 As shown, a motor 5 is mounted on the top of the drill bit 1; the motor 5 is located near the center of the top of the drill bit 1; the top of the motor 5 is connected to the threaded rod 12. During operation, the motor 5 mounted on the top of the drill bit 1 is rotated, and the rotation of the motor 5 directly drives the threaded rod 12 to rotate. The rotation of the threaded rod 12 makes the sampling process more efficient. Compared with traditional sampling tools, the rotating threaded rod 12 can quickly cut into and collect powder, greatly shortening the sampling time, especially when a large amount of powder needs to be sampled, significantly improving work efficiency.

[0028] like Figures 1 to 4 As shown, an elastic cloth 6 is fixed to the outer wall of the telescopic rod 4; the bottom of the elastic cloth 6 is connected to the handrail 42; the elastic cloth 6 is wrapped around the middle of the telescopic rod 4. By providing an elastic cloth 6 on the outer wall of the telescopic rod 4, the telescopic rod 4 can automatically expand and contract when it extends and retracts at the bottom of the circular rod 41. This setting can reduce the problem of powder falling into the middle of the telescopic rod 4 during the sampling process, which would affect the extension and retraction of the telescopic rod 4, and improve the stability of the telescopic rod 4 when it extends and retracts at the bottom of the circular rod 41.

[0029] The working principle is as follows: First, the device is placed in the powder to be sampled. At this time, the top of the drill bit 1 contacts the powder. Then, the threaded rod 12 is rotated to collect the powder from the outer wall of the threaded rod 12 into the hollow tube 13. When the powder is collected into the hollow tube 13, the stirring blades 21 set on the outer wall of the circular rod 2 can rotate to stir the powder. Then, the sealing gasket 31 is connected to the inner wall of the hollow tube 13 by the screw 32. By tightening the screw 32, the sealing gasket 31 is fully compressed to achieve a good sealing effect. When it is necessary to sample powder at different depths, the telescopic rod 4 can be extended or retracted towards the drill bit 1 to make the threaded rod 12 reach the required depth. Then, the telescopic rod 4 is stopped to perform sampling. The rotation of the motor 5 installed on the top of the drill bit 1 is controlled. The rotation of the motor 5 directly drives the threaded rod 12 to rotate. The rotation of the threaded rod 12 makes the sampling process more efficient. Finally, the elastic cloth 6 is provided on the outer wall of the telescopic rod 4, which allows the telescopic rod 4 to automatically expand and contract when it extends or retracts at the bottom of the circular rod 41.
