Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco leaf sampling technology, and in particular to a plant leaf sampling device. Background Technology
[0002] Tobacco is an annual or short-lived perennial herb belonging to the Solanaceae family. The plant is covered with glandular hairs, and the stem is 0.7–2 meters tall. The petioles are inconspicuous or winged. The panicles are terminal. The calyx is tubular or tubular-campanulate, and the corolla is funnel-shaped with a pink apex. Sampling devices are needed to sample tobacco leaves when studying their oil content and softness.
[0003] Existing tobacco sampling equipment is typically inefficient and cumbersome to operate, making it difficult to select tobacco leaves from different parts of the plant in a single operation. For example, operators need to manually place the tobacco leaves at specific locations for cutting, a complex process that easily leads to leaf loss. Furthermore, existing sampling methods are inefficient in effectively collecting the cut tobacco leaves.
[0004] Chinese utility model patent CN216410702U discloses a sampling and slitting device for reconstituted tobacco leaves produced using a papermaking method. This device utilizes an operating wheel and a moving rack, along with multiple operating components and slitting components simultaneously mounted on a rotating rod, to obtain multiple samples in a single sampling operation, thus improving sampling efficiency. However, the multiple operating components and independent sampling plates make the device complex and bulky. Furthermore, a single row of samplers is insufficient for effectively slitting the tobacco leaves as a whole, and it also fails to efficiently collect the cut tobacco leaves.
[0005] Therefore, there is an urgent need for a tobacco sampling device that can improve the speed and efficiency of tobacco sampling and facilitate sampling of tobacco leaves from different parts. Utility Model Content

[0031] Example 1
[0032] See Figure 1-4This embodiment provides a plant leaf sampling device, including a base 1, a support frame 2, a driving component, and a sampling and cutting assembly 3. The support frame 2 is mounted above the base 1, and the sampling and cutting assembly 3 is located above the base 1. The driving component is mounted on the support frame 2 and connected to the sampling and cutting assembly 3. The sampling and cutting assembly 3 includes a mounting plate 301, a mounting cylinder 302, and a cutting ring 304. Multiple mounting cylinders 302 are evenly distributed in multiple rows and columns on the bottom surface of the mounting plate 301. A push rod 305 is connected to the bottom end of the mounting cylinder 302, and the cutting ring 304 is sleeved on the push rod 305 and slidably connected inside the mounting cylinder 302.
[0033] The upper surface of the base 1 is a tobacco leaf placement platform, on which a tobacco leaf fixing device is provided to fix the tobacco leaves on the tobacco leaf placement platform for subsequent cutting.
[0034] The upper part of the base 1 has multiple evenly distributed collection holes 308, which are positioned one-to-one with the mounting cylinder 302 and aligned with the cutting ring 304 and the push rod 305 to facilitate the collection of cut tobacco leaves. The diameter of the collection holes 308 is the same as that of the cutting ring 304, while the diameter of the push rod 305 is smaller than that of the collection holes 308. This allows the push rod 305 to push the cut tobacco leaves into the collection holes 308, facilitating sampling and collection of the tobacco leaves.
[0035] See Figure 2 and Figure 3 The bottom of the mounting cylinder 302 has a circumferential sliding groove, and a spring telescopic rod 303 is installed in the sliding groove. One end of the spring telescopic rod 303 is connected to the top of the sliding groove, and the other end is connected to the top of the cutting ring 304. The upper part of the cutting ring 304 is slidably connected in the sliding groove through the spring telescopic rod 303.
[0036] During use, the driving component drives the mounting plate 301 to move downward, which in turn moves the mounting cylinder 302 downward. When the mounting cylinder 302 moves downward, it drives the cutting ring 304 to cut the tobacco leaves on the base 1. The bottom end of the cutting ring 304 contacts the tobacco leaves. As the mounting cylinder 302 moves downward, the upper part of the cutting ring 304 slides upward in the sliding groove and squeezes the spring telescopic rod 303. The spring telescopic rod 303 can improve the cutting effect of the cutting ring 304 on the tobacco leaves. At the same time as the cutting ring 304 moves upward, the mounting cylinder 302 drives the push rod 305 to push the cut tobacco leaves downward, so that they fall into the collection hole 308.
[0037] See Figure 4A pull-out storage assembly 309 is provided inside the base 1, located below the collection holes 308. The storage assembly 309 includes a collection component and a placement plate 3091 slidably connected within the base 1. The collection component includes multiple upward-facing collection slots 3094 corresponding to the positions of the collection holes 308, and a connecting plate 3093 located in the center. The collection slots 3094 are connected as a whole by connecting blocks and the connecting plate 3093. The placement plate 3091 has mounting slots 3092 adapted to the collection component, and the collection component is installed in the mounting slots 3092. The connecting plate 3093 is located between the two rows of collection slots 3094 in the middle, and has two handle openings for easy retrieval and placement of the entire collection component.
[0038] In use, after cutting, the tobacco leaves fall into the collection trough 3094 through the collection hole 308, which can collect the tobacco leaves. Then, the placement plate 3091 is pulled to one side from the base 1 to open, and the collection piece is moved upward through the handle to be taken out from the installation groove 3092, which makes it convenient to select tobacco leaf samples in the collection trough 3094.
[0039] The tobacco leaf placement platform has a tobacco leaf fixing area 101 in the middle. The tobacco leaf fixing device includes multiple positioning holes and positioning nails 1011 on both sides of the tobacco leaf fixing area 101. The tobacco leaves are fixed on the tobacco leaf placement platform by the positioning nails 1011 and the positioning holes.
[0040] When cutting tobacco leaves, the central vein of the tobacco leaf is aligned with the tobacco leaf fixing area 101. Then, the positioning pin 1011 is inserted through the tobacco leaf into the positioning hole to fix the tobacco leaf. This makes it convenient for the cutting ring 304 to cut the upper, middle and lower parts of the tobacco leaf on both sides, so as to facilitate subsequent research on the oil content of the tobacco leaf. The positioning pin 1011 can also fix different positions of the tobacco leaf, so that the cutting ring 304 can cut the middle of the tobacco leaf, so as to facilitate subsequent research on the integration softness of the tobacco leaf.
[0041] Example 2
[0042] The content of this embodiment is basically the same as that of Embodiment 1 above, except that:
[0043] The aforementioned driving component includes a threaded rod 306 and a guide rod 307. The support frame 2 has one threaded hole and two guide holes. The guide holes are located on both sides of the threaded hole. The threaded rod 306 is threadedly connected to the support frame 2 through the threaded hole. The bottom end of the threaded rod 306 is connected to the mounting plate 301 by a bearing, so that the mounting plate 301 moves up and down with the threaded rod 306 but does not rotate with it.
[0044] The guide rod 307 is slidably connected to the support frame 2 through the guide hole, and its bottom end is also fixedly connected to the mounting plate 301 to ensure that the mounting plate 301 remains stable during movement and to prevent the mounting plate 301 from tilting or shifting.
[0045] When cutting tobacco leaves, rotating the threaded rod 306 causes the mounting plate 301 to move downwards. As the mounting plate 301 moves downwards, it causes the two guide rods 307 to move downwards along the guide holes. The mounting plate 301 causes the mounting cylinder 302 and the cutting ring 304 to move downwards to cut the tobacco leaves. When the threaded rod 306 rotates, the two guide rods 307 can limit the mounting plate 301. When the mounting plate 301 moves downwards, the two guide rods 307 can guide and support it, which facilitates rapid cutting and sampling of tobacco leaves and improves the effectiveness of the device.
[0046] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
