Description

Technical Field

[0001] The utility model relates to the field of pine wood nematode separation, in particular to a pine wood nematode rapid detection device. Background Art

[0002] The pine wood nematode detection device is a device used to detect the presence of pine wood nematodes. Since the spread of pine wood nematodes is very destructive, especially for pine forestry and wood trade, early detection and control of the spread of pine wood nematodes is crucial. When the pine wood nematode detection device is used, a centrifugal device is required to fully mix the wood sample with the detection liquid. The centrifugal device in the prior art cannot fix test tubes of different specifications. When centrifuging test tubes of different sizes, different specifications of clamps are required to clamp the test tubes. The staff also needs to replace the clamps one by one, which is inconvenient to operate and cannot meet the detection needs.

[0003] According to the Chinese application number: CN202322184194.2, a pine wood nematode rapid detection device is provided. The solution is provided with a sample placement component, an air supply component and a drive component. Under the cooperation of the sample placement component, the air supply component and the drive component, when the rotating frame drives the test tube to rotate, the two clamping blocks can jointly press the test tube in the inner tube, and can fix the test tubes of different diameters, providing convenience for the use of the pine wood nematode detection device.

[0004] However, it is not convenient to separate pine wood nematodes during the detection process, and the pine wood nematodes need to be separated in advance, which is not conducive to the detection of pine wood nematodes. Therefore, we propose a rapid detection device for pine wood nematodes. Utility Model Content
