Description

Technical Field

[0001] The utility model relates to the technical field of nematodes, in particular to a device for separating nematodes from grass seeds. Background Art

[0002] Grain nematodes are a type of plant parasitic nematode with strong host specialization. They typically infect monocotyledons and form galls on the host's seeds, stems (base, tips, and trunk), and leaves. When the plant matures, the galls fall off and become mixed with the seeds. The long-distance transportation of infected seeds is a key route of grain nematode transmission. Important grain nematode species, such as the bentgrass grain nematode and the lethal grain nematode, are listed as quarantine pests in many countries.

[0030] As a technical optimization solution of the present invention, the filter bag 4 made of non-woven fabric has the advantages of good filtering effect, wear resistance and stretch resistance.

[0031] The working principle and use process of the utility model are as follows: when in use, the operator puts the filter bag 4 into the cylinder 2, and the sieve plate 3 can support the bottom of the filter bag 4. Then the operator puts in the pressing plate 5 and the supporting column 7, so that the pressing ring 8 fits with the filter bag 4. Then the operator rotates the turning handle to drive the first threaded rod 13 to rotate, so that the first threaded rod 13 is threadedly connected with the sleeve 12.

Then, when the operator needs to separate the nematodes of forage seeds such as orchard grass seeds, tall fescue seeds, and bentgrass seeds, , pour the grass seed sample into the filter bag 4, and add water until the grass seed is completely immersed; after 24 hours, open the electromagnetic discharge valve 25, collect the water in the cylinder 2 into the collection box 26, and then conduct subsequent detection of nematodes; use the crushing rod 20 to break up the remaining wet grass seeds until most of the grass seeds are only one-quarter of their original size. If the grass seeds contain galls, they will be broken by the crushing rod 20, so that the nematodes will escape from the broken galls, thereby separating more nematodes. After the grass seeds are broken, continue to add water until the grass seeds are completely immersed. After soaking for 24 hours, open the electromagnetic discharge valve 25, collect the water in the cylinder 2 into the collection box 26, and then conduct subsequent detection of nematodes. At this time, more accurate detection data that is more in line with reality can be obtained;

[0032] By setting the pressure plate 5, the bottom of the inner wall of the filter bag 4 can be prevented from contacting the crushing rod 20 and being damaged. By setting the support column 7, the side of the inner wall of the filter bag 4 can be prevented from contacting the crushing rod 20 and being damaged. By setting the pressure ring 8, the filter bag 4 can be pressed and fixed.
