Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production, and more particularly to a handheld tobacco leaf punching and sampling device. Background Art

[0002] Tobacco leaf quality inspection involves testing various physiological indicators, such as photosynthesis and respiration, as well as DNA and protein analysis. Before testing, tobacco leaf sampling is required. However, in practice, this is often done manually by tearing the leaves into pieces or using a cylindrical sampling knife to repeatedly rotate the leaves and cut into circular pieces.

[0003] Tobacco leaf sampling plays an important role in subsequent biological research. Under any circumstances, the collection of samples is a problem faced by scientific researchers, especially the collection of tobacco leaves. It is necessary to ensure randomness and freshness, and also to ensure that the sample amount collected can carry out subsequent biological research. And some existing samplers are used for tobacco leaf sampling, but the small pieces taken out by some existing samplers are inconvenient to store. Generally, the staff needs to take samples and then put the taken small pieces into a sample storage bottle for storage, which will undoubtedly affect work efficiency, and a certain degree of pollution and damage will be produced to the sample tobacco leaves, and certain interference will be caused to the experimental data in the back, affecting the control of tobacco leaf growth. Moreover, such an operating method will not only reduce the efficiency of operation, but also make the whole operating process more cumbersome, and even need two people to cooperate sometimes, which has reduced the feasibility of single-person operation, and can not ensure that the leaf sample taken out can be put into the test tube bottle in time, causing the loss or confusion of the leaf sample. At the same time, when using a cylindrical sampling knife to repeatedly rotate the leaves to cut off circular leaves, the sample tobacco leaves are easily embedded in the tube and difficult to remove, which may also cause the leaf samples to be out of order or missed.

[0004] Therefore, in response to the current problems, how to provide a handheld tobacco leaf punching sampling device that can ensure simple structure, easy use, strong portability, and convenient storage of sample tobacco leaves, which is conducive to field sampling, and at the same time, a tobacco leaf quality inspection sampling device that is convenient for removing samples, is a problem that technical personnel in this field urgently need to solve.

The function of the pressure ring 62 is to fix the blade and press the blade first. Then continue to press the upper pressing plate 1, and the telescopic sleeve 61 will shrink. At this time, the sampling ring knife 32 will touch the blade to achieve the cutting of the blade. At the same time, push the sliding rod 41 by hand so that the push plate 42 can push the cut blade into the sampling bottle 5. After the cutting is completed, release the upper pressing plate 1 by hand, and the upper pressing plate 1 will automatically rebound. The telescopic sleeve 61 loses pressure and automatically stretches to its natural state due to gravity. In this way, the pressure ring 62 can not only fix the blade in advance when cutting, but also protect the sampling ring knife 32 in the uncut state to avoid accidental scratches.
