Description

Technical Field

[0001] This utility model belongs to the field of tobacco detection technology, specifically relating to a quantitative sampling device for tobacco dust samples. Background Technology

[0002] The tobacco dust samples used in tobacco experiments are usually made by equilibrating tobacco leaves or shredded tobacco in a constant temperature and humidity environment of (22±1)℃ and (60±2)% for more than 48 hours, and then pulverizing them into tobacco dust using a high-speed universal pulverizer with a 60-80 mesh sieve. The tobacco dust samples have a fine texture, and the weight is difficult to control during fine sampling. For example, in thermogravimetric analysis experiments, the required sample amount is 10-20 mg. Due to the lack of an effective quantitative sampling device, repeated weighing is required in actual sampling, which seriously affects the experimental efficiency and increases the labor intensity of the operators. In addition, the tobacco dust samples have a large amount of dust, and repeated weighing and sampling will increase the probability of spillage on the test bench, which requires the operators to clean up, increasing the labor intensity of the operators.

[0003] Therefore, how to design a quantitative sampling device for tobacco dust samples to better achieve quantitative sampling of tobacco dust samples and reduce the labor intensity of operators has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative sampling device for tobacco dust samples to solve the aforementioned technical problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A quantitative sampling device for tobacco dust samples includes a metering container, a handheld plate, and a scraper. The lower end of the handheld plate is perpendicularly connected to one side of the metering container, and the upper part of the handheld plate is rotatably connected to the upper part of the scraper. The lower side of the scraper is used to fit against the end face of the metering container opening. A leakage hole is provided at the lower part of the handheld plate, and the leakage hole is close to the metering container.

[0007] Preferably, the material leakage hole is an oblong hole extending in the vertical direction.

[0008] Preferably, the measuring container is a cylindrical container.

[0009] Preferably, the upper end of the handheld plate and the upper end of the scraper are both arc-shaped structures.

[0010] Preferably, a screw is vertically arranged on the upper part of the handheld plate, and a threaded hole for cooperating with the screw is provided on the upper part of the scraper.

[0011] Preferably, a pin is vertically arranged on the upper part of the handheld plate, and a mounting hole is provided on the upper part of the scraper for rotating with the pin. A limiting block is provided on the end of the pin away from the handheld plate for blocking the scraper.

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

[0013] This utility model discloses a quantitative sampling device for tobacco dust samples. In use, after scooping tobacco dust samples from a storage container using a quantitative container, a rotating scraper scrapes the portion of the tobacco dust sample above the opening of the quantitative container into the storage container. Simultaneously, the scraper also scrapes tobacco dust samples adhering to the lower end of the hand-held plate through a leakage hole into the storage container. This ensures that the sample volume taken each time is the same as the amount of tobacco dust sample in the quantitative container, thus achieving effective quantitative sampling of tobacco dust samples. This reduces the labor intensity of operators and improves experimental efficiency. Attached Figure Description

[0019] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0020] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0021] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0022] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0023] like Figure 1 As shown in the figure, this utility model embodiment provides a quantitative sampling device for tobacco dust samples, which includes a quantitative container 11, a hand plate 21, and a scraper 31. The lower end of the hand plate 21 is vertically connected to one side of the quantitative container 11, and the upper part of the hand plate 21 is rotatably connected to the upper part of the scraper 31. The lower side of the scraper is used to fit against the end face 12 of the container opening of the quantitative container. The lower part of the hand plate 21 is provided with a leakage hole 22, which is close to the quantitative container 11.

[0024] The quantitative sampling device for tobacco samples provided in this embodiment of the invention involves using a quantitative container 11 to scoop tobacco samples from a storage container. Then, a scraper 31 is rotated to scrape the portion of the tobacco sample above the opening of the quantitative container into the storage container. Simultaneously, the scraper also scrapes tobacco samples adhering to the lower end of the handheld plate through the leakage hole 22 into the storage container, preventing tobacco samples outside the quantitative container from entering the sample container. This ensures that each sampling volume is the same as the amount of tobacco sample in the quantitative container, thus achieving better quantitative sampling of tobacco samples. This reduces the workload of operators and improves experimental efficiency.

[0025] Furthermore, the discharge hole 22 is an oblong hole extending in the vertical direction, which makes it easy for the tobacco sample to fall out of the discharge hole.

[0026] Preferably, the measuring container 11 is a cylindrical container.

[0027] Specifically, the upper end of the handheld plate 21 and the upper end of the scraper 31 are both arc-shaped structures 23, which can better prevent the operator from being scratched.

[0028] In one embodiment, a screw is vertically disposed on the upper part of the handheld plate, and a threaded hole for engaging with the screw is disposed on the upper part of the scraper. This design utilizes the threaded engagement between the threaded hole and the screw to achieve connection while effectively preventing the scraper from detaching from the screw. It also allows for rotation of the scraper, conveniently enabling a rotatable arrangement of the scraper on the handheld plate.

[0029] In another embodiment, a pin 41 is vertically disposed on the upper part of the handheld plate 21, and a mounting hole for rotatably engaging with the pin is disposed on the upper part of the scraper 31. A limiting block for engaging with the scraper is disposed on the end of the pin away from the handheld plate. With this design, the limiting block prevents the scraper from detaching from the pin, and the rotatable engagement between the mounting hole and the pin allows the scraper to rotate around the pin, thus achieving a rotatable connection between the scraper and the handheld plate. Preferably, the pin is threaded to the upper part of the handheld plate.

[0030] Understandably, the capacity of the quantitative sampling container can be designed according to the sampling amount to meet the quantitative sampling needs of different sampling amounts.

[0031] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
