9. the receipts of the automatic collecting device of wheel animalcule High Density Cultivation described in a kind of claim 1 to 8 any claim and its ovum
Set method, it is characterised in that: wheel animalcule is trained in the water between the cultivation flume (1) inner wall and outer filter net (2) outer surface
Health is living, is detached from the ovum of polypide and newly hatched larvae enters outer filter net (2) through the outer filter net (2) and internal layer filters
It between net (3), then enters in collecting chamber (10) from the drainage hole (9), enters collecting tank through the collecting pipe (11)
(502), ovum and newly hatched larvae cannot penetrate the filter screen of the collecting tank (502) bottom；Liquid in the collecting tank (502)
After position rises triggering liquid-level switch (505), the motor-driven valve (504) is opened, and ovum and larva are sucked away under differential water pressures effect, into
Enter later collection device, liquid level decreases, and completes primary automatic collection process.
