Description

Technical Field

[0001] This utility model relates to the field of sampler technology, and in particular to a sampler for tobacco root and stem diseases. Background Technology

[0002] Tobacco root and stem diseases refer to a class of important diseases that mainly infect the root and stem parts of tobacco plants. They usually overwinter in the soil or on diseased plant debris and are spread through water flow, agricultural operations, diseased soil, diseased seedlings, or insects, posing a serious threat to tobacco production and often leading to plant wilting, death, a significant drop in yield, and a marked reduction in quality.

[0003] However, in the existing technology, most existing disease sample collectors cannot cut tobacco roots and stems, requiring additional cutting tools to cut the roots and stems for sampling. Furthermore, most existing samplers cannot accurately collect the diseased parts, requiring secondary cutting. In addition, most existing samplers are not extendable to achieve a larger storage space. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a sample collector for tobacco root and stem diseases.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tobacco root and stem disease sample collector, comprising: a collection tube body, a collection mechanism disposed inside the collection tube body, a telescopic mechanism disposed at the rear end of the collection mechanism, the collection tube body including a sealing cap, a rotating shaft disposed at the rear end of the sealing cap, a first collection tube disposed at the lower end of the rotating shaft, a second collection tube disposed at the lower end of the second collection tube, the collection mechanism including a fixed guide rail, a sealing plate disposed at the rear end of the fixed guide rail, a telescopic push-pull rod disposed at the upper end of the sealing plate, a semi-circular fixing member disposed on the outer side of the telescopic push-pull rod, a trapezoidal pushing member disposed at the rear end of the semi-circular fixing member, a cutting member disposed at the rear end of the trapezoidal pushing member, a storage groove disposed at the lower end of the cutting member, a fixing buckle disposed at the left end of the storage groove, a semi-annular sealing member disposed at the lower end of the fixing buckle, and an elastic buckle disposed on the outer side of the semi-annular sealing member.
