[0042] Existing tobacco sampling tools use a clamping mechanism that moves up and down to remove a portion of tobacco from the tobacco box before testing it. This facilitates sampling and protects fingers. However, during use, due to the significant differences in tobacco quality at various locations within the tobacco box, and the large volume of the tobacco box storing the tobacco, the tobacco sampled by the clamping mechanism can produce deviations in the test results, affecting the tobacco sampling test results. To address this issue, the present embodiment provides an automated tobacco sampling device that can stir the tobacco in the box 2 before sampling. This addresses the problem of existing sampling tools failing to stir the tobacco in the box 2 during use, resulting in deviations in the test results.

[0043] like Figure 1-Figure 5As shown, in this embodiment, the automatic tobacco sampling device includes a support 1, a housing 2, a drive assembly 3, a sampling assembly 4, and a stirring assembly 5. Among them, the housing 2 is arranged on the support 1 and is used to contain tobacco. The drive assembly 3 is arranged on the support 1. The sampling assembly 4 is arranged below the drive assembly 3. The sampling assembly 4 can move in a vertical direction under the action of the drive assembly 3 and is used to collect tobacco in the housing 2. The stirring assembly 5 includes a first push rod 51, a first rotating disk 52, and a baffle 53. The first rotating disk 52 is located below the sampling assembly 4. The fixed end of the first push rod 51 is connected to the sampling assembly 4, and the telescopic end of the first push rod 51 is connected to the first rotating disk 52. The baffle 53 is arranged on the first rotating disk 52. The first rotating disk 52 can slide in a vertical direction relative to the sampling assembly 4 under the action of the first push rod 51, so that the baffle 53 opens or blocks the sampling port of the sampling assembly 4. The baffle 53 is used to stir the tobacco in the housing 2. Specifically, a housing 2 for holding tobacco is provided at the bottom of a support 1. A drive assembly 3 is supported on both sides of the top of the support 1. A sampling assembly 4 is provided below the drive assembly 3. The drive assembly 3 is used to drive the sampling assembly 4 to rise and fall vertically, allowing the sampling assembly 4 and the stirring assembly 5 to extend into or out of the tobacco in the housing 2. When extending into the tobacco in the housing 2, the sampling assembly 4 and the stirring assembly 5 can rotate to stir and sample the tobacco. A first turntable 52 is provided with a through hole. The first turntable 52 is driven by a first push rod 51 to move upward vertically relative to the sampling assembly 4, allowing the sampling assembly 4 to pass through the through hole and extend into the tobacco. When the blocking piece 53 completely blocks the sampling port of the sampling assembly 4, the tobacco in the housing 2 can be stirred before sampling. This solves the problem that existing sampling tools do not stir the tobacco in the housing 2 during use, resulting in deviations in the sampling results, thereby affecting the accuracy of the sampling test. Under the action of the first push rod 51, the first turntable 52 can continue to move upward in the vertical direction relative to the sampling component 4, so that the sampling port of the sampling component 4 exceeds the baffle 53, that is, the baffle 53 can open the sampling port, and the tobacco that has been fully stirred will randomly pass through the sampling port and be stored in the sampling component 4. After the sampling is completed, the sampling component 4 and the stirring component 5 are separated from the tobacco in the box body 2 by the driving component 3, so as to facilitate the test personnel to sample the tobacco and conduct relevant tests, thereby achieving the randomness of the test samples, the scientific nature of the test process and the accuracy of the test results.

[0044] Further, continue to refer to Figure 1-Figure 5The sampling assembly 4 includes a motor 41, a second turntable 42, and a sampling tube 43. The motor 41 is disposed in the drive assembly 3, and the output end of the motor 41 is connected to the second turntable 42 to drive the second turntable 42 to rotate. One end of the sampling tube 43 is connected to the second turntable 42, and the other end of the sampling tube 43 is movably arranged on the first turntable 52. The sampling tube 43 can be inserted into the housing 2 under the action of the drive assembly 3. Specifically, the sampling assembly 4 is inserted vertically into the tobacco in the housing 2 under the action of the drive assembly 3. Subsequently, the second turntable 42 rotates under the drive of the motor 41, driving the sampling tube 43 to rotate along the circumferential direction of the second turntable 42. When the baffle 53 blocks the sampling port of the sampling tube 43, the sampling tube 43 stirs the tobacco. When the baffle 53 opens the sampling port of the sampling tube 43, the sampling tube 43 samples the tobacco.

[0045] Further, continue to refer to Figure 1-Figure 5 There are multiple sampling tubes 43, and the multiple sampling tubes 43 are spaced apart along the circumference of the second turntable 42. The angle between the openings of the sampling ports of two adjacent sampling tubes 43 is less than or equal to 90° and greater than or equal to 30°. Specifically, if the first turntable 52 is not provided with a baffle 53, the sampling tubes 43 extend into the tobacco of the housing 2. When the motor 41 drives the second turntable 42 and the sampling tubes 43 to rotate clockwise, the back surfaces of all the sampling ports generate a driving force on the tobacco, stirring it, and preventing the tobacco from passing through the sampling ports into the sampling tubes 43. When the motor 41 drives the second turntable 42 and the sampling tubes 43 to rotate counterclockwise, the fully stirred tobacco passes through the sampling ports into the sampling tubes 43. In this embodiment, the angle between the openings of the sampling ports of two adjacent sampling tubes 43 is 90°, minimizing the time it takes for the tobacco to pass through the sampling ports and improving sampling efficiency.

[0046] Further, continue to refer to Figure 1-Figure 5 A plurality of baffles 53 are provided corresponding to the number of sampling tubes 43 , and each baffle 53 can block the sampling port of the corresponding sampling tube 43 . Specifically, there are four sampling tubes 43 , and the number of corresponding baffles 53 is also four. The four baffles 53 are respectively provided below each through-hole of the first turntable 52 , so as to facilitate blocking or opening the sampling port of the respective sampling tube 43 .

[0047] Further, continue to refer to Figure 1-Figure 5The driving assembly 3 includes a top plate 31, a driving mechanism 32, a telescopic rod 33 and a bottom plate 34. The bottom plate 34 is arranged between the top plate 31 and the sampling assembly 4. The two ends of the telescopic rod 33 are respectively connected to the top plate 31 and the bottom plate 34. The driving mechanism 32 is arranged on the top plate 31. The driving mechanism 32 is used to drive the bottom plate 34 to move away from or closer to the top plate 31. Specifically, in order to ensure the reliability of the device during use, the bracket 1 and the top plate 31 are connected by welding, and the bracket 1 and the top plate 31 are made of stainless steel, which can make the connection between the top plate 31 and the bracket 1 reliable and not prone to breakage. The number of telescopic rods 33 is set to four, and the telescopic rods 33 are connected to the top plate 31 and the bottom plate 34 by welding, which can make the connection between the telescopic rods 33 and the top plate 31 and the bottom plate 34 reliable and not prone to breakage, thereby making it less likely for the bottom plate 34 to malfunction when moving up and down. The driving mechanism 32 is started, and under the action of the telescopic rod 33, the bottom plate 34 moves away from the top plate 31, so that the sampling component 4 and the stirring component 5 extend into the tobacco in the box body 2. After the tobacco is stirred and sampled, under the action of the driving mechanism 32 and the telescopic rod 33, the bottom plate 34 gradually moves closer to the top plate 31, so that the sampling component 4 and the stirring component 5 are detached from the box body 2, making it convenient to obtain the tobacco in the sampling tube 43 for random inspection testing.

[0048] Further, continue to refer to Figure 1-Figure 5 The drive mechanism 32 includes a second push rod 321 and a sliding frame 322. The fixed end of the second push rod 321 is connected to the top plate 31, and the telescopic end of the second push rod 321 is connected to the sliding frame 322. A slide rail 6 is provided on the bottom plate 34, and the slide rail 6 is arranged at an angle relative to the bottom plate 34. The sliding frame 322 is slidably connected to the slide rail 6. Under the action of the second push rod 321, the sliding frame 322 slides along the length of the top plate 31, so that the bottom plate 34 drives the sampling assembly 4 in the vertical direction. Specifically, under the action of the second push rod 321, the sliding frame 322 slides rightward along the guide rail 7 of the top plate 31. At the same time, the two sides of the sliding frame 322 slide in cooperation with the slide rail 6, thereby moving the bottom plate 34 downward along the telescopic rod 33, and the sampling tube 43 moves downward and is inserted into the tobacco in the box 2 for stirring and sampling. After sampling is completed, the second push rod 321 retracts, and the sliding frame 322 slides leftward along the guide rail 7. Simultaneously, the sliding of the sliding frame 322 cooperates with the movement of the bottom plate 34 upward along the telescopic rod 33, allowing the sampling tube 43 to be removed from the tobacco in the box 2. Optionally, the first push rod 51 and the second push rod 321 are hydraulically or electrically driven.

[0049] Further, continue to refer to Figure 1-Figure 5The sliding frame 322 includes a frame body 3221 and a slider 3222 disposed on the frame body 3221. The top plate 31 is provided with a guide rail 7. The frame body 3221 is slidably disposed on the guide rail 7. The slider 3222 is located within the slide rail 6 and can slide relative to the length of the slide rail 6 to allow the sampling assembly 4 to extend into the box body 2. Specifically, to prevent the slider 3222 from malfunctioning while sliding within the slide rail 6, the slider 3222 is fixedly connected to the frame body 3221. The slider 3222 is cylindrical in shape, which ensures that the slider 3222 is evenly stressed and less likely to become stuck. The frame body 3221 is provided with a slide groove, the guide rail 7 of the top plate 31 is set as a convex structure, and the slide groove is correspondingly set as a convex groove. The guide rail 7 is located in the slide groove and can slide relative to the slide groove. The frame body 3221 slides relative to the top plate 31. At the same time, the slider 3222 slides relative to the slide rail 6, so that the bottom plate 34 is close to or away from the top plate 31 under the action of the telescopic rod 33, thereby driving the stirring component 5 and the sampling component 4 to move in the vertical direction.

[0050] Further, continue to refer to Figure 1-Figure 5 There are two slide rails 6, which are respectively arranged on both sides of the bottom plate 34. The first end of the slide rail 6 is fixedly connected to the bottom plate 34, and the second end of the slide rail 6 is suspended, and the second end of the slide rail 6 is higher than the first end of the slide rail 6. There are two sliders 3222, which are respectively arranged on both sides of the frame body 3221 and slide in cooperation with the corresponding slide rail 6. Specifically, slide rails 6 are provided on both sides of the bottom plate 34, and the inner wall of the slide rail 6 is slidably connected to the outer circumference of the slider 3222. Optionally, the angle between the slide rail 6 and the bottom plate 34 ranges from 35 to 45 degrees. In the initial state, the slider 3222 is located at the second end of the slide rail 6, that is, when the slider 3222 is at the highest point relative to the slide rail 6, the telescopic rod 33 is in a retracted state, and the sampling tube 43 does not extend into the box body 2. The driving mechanism 32 is started, and the second push rod 321 pushes the sliding frame 322 to slide along the guide rail 7. The slider 3222 slides from the second end of the slide rail 6 to the first end, that is, the slider 3222 is at the lowest point relative to the slide rail 6, the telescopic rod 33 is in an extended state, and the sampling tube 43 is extended into the tobacco in the box body 2 for stirring and taking materials.

[0051] Further, continue to refer to Figure 1-Figure 5 The automatic tobacco sampling device further includes a plurality of anti-slip strips 8, which are protruding from both sides of the bracket 1. Specifically, the plurality of anti-slip strips 8 are provided on both outer sides of the bracket 1. During the handling process, the anti-slip strips 8 provide greater friction when the hand contacts the bracket 1, thereby making the handling safer and more reliable for the operator and preventing the bracket from falling out of the hand.

[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
