Description

TECHNICAL FIELD

[0001] The utility model belongs to nematode sample processing technical field, concretely relates to a nematode sample impurity removal device. BACKGROUND

[0002] Bursaphelenchus xylophilus is a kind of nematode parasitized on pine trees and other coniferous trees. It is small in size and in the form of a worm. This nematode is transmitted by media such as Monochamus and invades pine trees, which can destroy the transport tissues of pine trees, block the transport of water and nutrients in pine trees, and cause pine trees to wither and die rapidly. It is a major destructive disease pathogen of pine trees. Therefore, the existing method is to detect and process the disease of pine wood by detecting the sample of bursaphelenchus xylophilus.

[0003] Before detecting the nematode sample, the nematode sample needs to be separated from the broken pine wood, that is, the nematode sample needs to be impurity-removed. The common method for processing the nematode sample in the existing market is shallow plate separation method. The shallow plate separation method mainly uses the active mobility of nematodes and the suspension characteristics of nematodes in water. After being stimulated by water, nematodes will actively swim out of the tissue and enter the water. Since the density of nematodes is slightly larger than that of water, they will slowly sink in still water. In this way, nematodes can be separated by collecting water.

[0004] However, in the above scheme, after the separation of nematodes is completed, a large amount of debris and other impurities from pine wood will be suspended on the surface of the water. When the shallow plate with a sieve hole is used to extract and separate nematodes, the impurities will inevitably be collected together with nematodes. If the impurities floating on the water surface need to be removed, manual operation is usually needed to complete the cleaning work at the present stage. However, this method not only has low efficiency, but also has complex operation process, increases the inconvenience and labor intensity of work, and seriously affects the efficient development of subsequent processing work after the separation of nematodes.
